Full Text FIELD OF THE INVENTION
The present invention relates to a cartridge which is
drawably provided in a stapler and equipped with a storage
chamber detachably accommodating a staple refill.
BACKGROUND OF THE INVENTION
Conventionally, for example, as disclosed in Japanese
Patent Application Laid-open No. 2002-200573 (Patent
Document 1), the cartridge provided in the stapler is
drawably attached to a stapler main body. The cartridge
includes a storage chamber, and the staple refill is
detachably attached to the storage chamber. A sheet-like
connected staple wound in a roll shape is stored in the
staple refill, and a leading end portion of the sheet-like
connscted staple is discharged from a discharge port of the
staple refill. Accordingly, in usage of the stapler, the
cartridge is drawn from the stapler main body to mount the
staple refill on the cartridge, and the cartridge on which
the staple refill is mounted is pressed into the stapler
main body.
In the conventional cartridge, even if the sheet-like
connected staple remains in the staple refill, the staple
refill can be taken off. Therefore, the staple refill can
be taken off from the cartridge while the sheet-like
connected staple is partway discharged from the discharge


port of the staple refill. In this case, the sheet-like
connected staple is broken, which results in a problem that
an obstacle such as clogging is generated.
In view of the foregoing, an object of the invention
is to provide a cartridge in which the staple refill cannot
be detached when the sheet-like connected staple remains
and the sheet-like connected staple can be drawn from the
staple main body while the staple refill is mounted when
the obstacle such as the clogging is generated.

A cartridge 70 is drawably provided in a stapler main
body 62. A storage chamber 82, an engaging member 85, and
a lock member 95 are provided in a cartridge main body 70A.
A staple refill 1 is detachably stored in the storage
chamber 82, the engaging member 85 engages one side of the
staple refill 1 stored in the storage chamber 82, and the
lock member 95 locks the engaging member 85.
The lock member 95 includes an abutting portion 97
which abuts on a sheet-like connected staple S, discharged
from a discharge port 4 6 of the staple refill 1, when the
staple refill 1 is stored in the storage chamber 82. When
the abutting portion 97 abuts on the sheet-like connected
staple S, the lock member 95 locks the engaging member 85
to prevent disengagement of the staple refill 1. When the
abutting portion 97 does not abut on the sheet-like
connected staple S, the lock member 95 unlocks the engaging
member 85 to enable the staple refill 1 to be disengaged.
The lock member 95 is oscillatably provided in the
cartridge main body 70A. The abutting portion 97 is formed


at one end and a latch portion 98 is formed at the other
end. The abutting portion 97 emerges to the inside of the
storage chamber 82 to abut on the sheet-like connected
staple S through a through-hole 74 formed in the cartridge
main body 70A. In the latch portion 98, when the abutting
portion 97 abuts on the sheet-like connected staple S, the
lock member 95 oscillates in a latch direction of the latch
portion 98 to latch the engaging member 85. When the
abutting portion 97 does not abut on the sheet-like
connected staple S, the lock member 95 oscillates in an
unlatch direction of the latch portion 98 to unlatch the
engaging member 85.
The cartridge 70 includes the storage chamber 82, the
engaging member 85, and the lock member 95. The storage
chamber 82 is attached to a stapler 61 which binds sheets
of paper with a staple,' and the staple refill 1 in which
the staple is accommodated is detachably stored in the
storage chamber 82. The engaging member 85 engages the
staple refill 1 stored in the storage chamber 82 to prevent
the disengagement from the storage chamber 82. The lock
member 95 latches the engaging member 85 to prevent the
release between the staple refill 1 and the engaging member
85. The lock member 95 includes the abutting portion 97
which abuts on the staple accommodated in the staple refill
1. The engaging member 85 is latched by the abutment
between the abutting portion 97 and the staple in the
staple refill 1, which prevents the release of the


engagement between the engaging member 85 and the staple
refill 1.
The staple refill stored in the cartridge and the
stapler main body in which the cartridge is drawably
provided will be described before the detailed description
of the cartridge. Fig. 10 is an overall perspective view

sectional perspective view of Fig. 10. Fig. 13 is a
sectional side view of Fig. 10. Fig. 14 is a set of six
drawings showing the staple refill of Fig. 10. Fig. 15 is
a sectional view showing a main part of Fig. 10. Fig. 16
is an explanatory view showing an operation of the staple
refill. Fig. 17 is an overall perspective view showing
another embodiment of a staple refill. Fig. 18 is an
exploded perspective view of Fig. 17.
The staple refill 1 is detachably attached to the
cartridge 70 provided in the stapler main body 62. As
shown in Figs. 12 and 13, a refill main body 2 of the
staple refill 1 includes a storage portion 40, the
discharge port 46, and a delivery passage 45. The sheet-
like connected staple S wound in a roll shape is stored in
the storage portion 40. The discharge port 46 discharges
the sheet-like connected staple S stored in the storage
portion 40. The delivery passage 45 delivers a leading end
portion S1 of the sheet-like connected staple S stored in
the storage portion 40 to the discharge port 46.


The delivery passage 45 is curved upward from the
discharge port 46 toward the inside of the storage portion
40 so as to deliver the leading end portion S1, located on
the upper side of the sheet-like connected staple S, to the
discharge port 46. A backward movement preventing member
31 which prevents the sheet-like connected staple S from
moving toward the reverse side of the discharge port 4 6
(toward the side of storage portion 40) is provided in the
delivery passage 45. The backward movement preventing
member 31 is integrated with refill main body 2.
The backward movement preventing member 31 is formed
such that a leading edge 31a slides 'on the side of a lower
surface S3 of the sheet-like connected staple S to latch a
connecting recess portion between the staples. The
delivery passage 45 includes a first guide passage 43 and a
second guide passage 42. The first guide passage 43
substantially formed in a linear shape is communicated with
the discharge port 46. The second guide passage 42 curved
upward is communicated with the storage portion 40. The
backward movement preventing member 31 is provided in the
second guide passage 42 while being exposed.
The delivery passage 45 includes an upper guide
surface 47 and a lower guide surface 48. The upper guide
surface 47 guides an upper surface S2 of the sheet-like
connected staple S, and the lower guide surface 48 guides
the lower surface S3 of the sheet-like connected staple S.
An upper guide surface 13a of the second guide passage 42


is coupled to an inner surface 41 of the storage portion
40. A lower guide surface of the second guide passage 42
is formed by curved one surface 26 (on the side of the
discharge port 46) of a guide projection portion 25
projected into the storage portion 40. The backward
movement preventing member 31 is formed so as to be
projected from one surface 26 (on the side of the discharge
port 46) of the guide projection portion 25. The other
surface 27 (on the side of the storage portion 40) of the
guide projection portion 25 is curved so as to guide the
sheet-like connected staple S stored in the storage portion
40.
Projection strips 20 and 35 are provided in the inner
surface of the storage portion 40 of the refill main body
2. The projection strips 20 and 35 slide on the outer
surface of the sheet-like connected staple S wound in a
roll shape, and smoothly rotate the sheet-like connected
staple S. An opening 8 communicated with the storage
portion 40 is formed in the refill main body 2.
Further, the staple refill will be described in
detail. As shown in Figs. 10 and 11, the refill main body
2 of the staple refill 1 includes an upper case 3 and a
lower case 5 which is detachably fixed to the upper case 3.
The upper case 3 is integrally formed by a synthetic resin,
and includes an upper wall 6, a left wall 7 provided in the
left end of the upper wall 6, and a right wall 9 provided
in the right end of the upper wall 6.


The upper wall 6 includes an upper semi-cylindrical
wall 11, a vertical wall 12 whose upper end is coupled to a
front end of the upper semi-cylindrical wall 11, a curved
wall 13 whose one end is coupled to a lower end of the
vertical wall 12, and a horizontal wall 15 whose rear end
is coupled to the other end of the curved wall 13. The
left wall 7 and the right wall 9 include circular walls 7a
and 9a and lower walls 7b and 9b respectively. The lower
walls 7b and 9b extending in a substantially horizontal
direction are coupled to lower ends of the circular walls
7a and 9a, respectively. The lower walls 7b and 9b are
projected downward from the horizontal wall 15. Latch holes
14 and 14 are formed in the lower walls 7b and 9b.
Further, an engaging shaft 16 is formed near the latch hole
14 in the rear side in the lower walls 7b and 9b.
A grip arm 18 extending backward is formed in the
upper portion of the upper semi-cylindrical wall 11. A rib
19 reinforcing the curved wall 13 is formed in the upper
surface of the curved wall 13. The opening 8 is formed in
the rear portion of the upper semi-cylindrical wall 11.
Further, the guide projection strip 20 guiding the sheet-
like connected staple S is provided in the inner surface of
the upper wall 6 of the upper case 3, i.e., in the inner
surfaces of the upper semi-cylindrical wall 11, the
vertical wall 12, the curved wall 13, and the horizontal
wall 15.
As shown in Figs. 12 and 13, similarly to the upper


case 3, the lower case 5 is integrally formed by a
synthetic resin, and includes a lower wall 21. The lower
wall 21 includes an arc wall 22 and a linear wall 23. The
arc wall 22 is formed in a substantially quarter arc shape,
and the rear end of the linear wall 23 is coupled to the
front end of the arc wall 22. The mound-shaped guide
projection 25 is formed in the linear wall 23. One surface
26 (on the side of the discharge port 46) of the guide
projection (guide projection portion) 25 is curved such
that a substantially constant gap is formed with the lower
surface 13a of the curved wall 13 of the upper case 3. The
other surface 27 (on the side of the storage portion 40) of
the guide projection 25 is curved so as to form the arc
like the arc wall 22. A top portion 29 of the guide
projection 25 is formed in a semi-circular shape.
A notch portion 30 is formed in a substantially
intermediate portion of the guide projection 25. The pawl-
shaped backward movement preventing member 31 is integrally
provided in the linear wall 23. The backward movement
preventing member 31 is located in the notch portion 30,
and is projected from the curved one surface 26. In the
linear wall 23, a substantially U-shaped notch recessed
portion 32 is formed in the front portion, and the rear
portion is formed so as to extend beyond the arc wall 22.
The guide band (projection strip) 35 guiding the sheet-like
connected staple S is projected in the inner surface of the
lower wall 21 of the lower case 5, i.e., in the inner


surfaces of the arc wall 22, the guide projection 25, and
the linear wall 23. Latch pawls 36 and 36 are formed on
both sides of the lower wall 21, and are detachably latched
in the latch holes 14 and 14 of the upper case 3.
In the staple refill 1, when the lower case 5 is
fitted between the lower wall 7b of the left wall 7 and the
lower wall 9b of the right wall 9 of the upper case 3, the
latch pawls 36 and 36 of the lower case 5 are latched in
the latch holes 14 and 14 of the upper case 3 to assemble
the refill main body 2. In the assembly, as shown in Fig.
12, the sheet-like connected staple S is placed in the
lower case 5, when the sheet-like connected staple S is
stored in the upper case 3 such that the leading end
portion SI of the sheet-like connected staple S wound
counterclockwise is located in the upper portion of the
upper case 3.
In the refill main body 2, the cylindrical storage
chamber 40 is formed by the upper semi-cylindrical wall 11
and vertical wall 12 of the upper wall 6, the arc wall 22
and the other surface (on the side of the storage portion
40) 27 of the guide projection (guide projection portion)
25 of the lower case 5, and the left wall 7 and right wall
9. The sheet-like connected staple S is positioned on the
lowest linear wall 23 by the arc wall 22 of the lower case
5 and the other surface 27 of the guide projection 25.
In the refill main body 2, the second guide passage
42, which is curved smoothly upward, is formed by the lower


surface 13a of the curved wall 13 of the upper case 3, one
surface (on the side of the discharge port 46) 26 of the
guide projection 25 of the lower case 5, and the left wall
7 and right wall 9. The second guide passage 42 is
upwardly curved toward the side of the storage portion 40,
and is communicated with the storage portion 40. In the
refill main body 2, the substantially linear first guide
passage 43 is formed by a lower surface 15a of the
horizontal wall 15 of the upper case 3, an upper surface
23a of the linear wall 23 of the lower case 5, and the left
wall 7 and right wall 9. That is, the delivery passage 45
is formed by the first guide passage 43 and the second
guide passage 42. The discharge port 4 6 is formed at the
front end of the delivery passage 45, and the sheet-like
connected staple S is sequentially discharged from the
leading end portion S1.
The delivery passage 45 includes the upper guide
surface 47 guiding the upper surface S2 of the sheet-like
connected staple S and the lower guide surface 48 guiding
the lower surface S3 of the sheet-like connected staple S.
The upper guide surface 47 is formed by the lower surface
15a of the horizontal wall 15 of the upper case 3 and the
lower surface 13a of the curved wall 13 of the upper case
3. The lower guide surface 4 8 is formed by the upper
surface 23a of the linear wall 23 of the lower case 5 and
one surface (on the side of the discharge port 46) 26 of
the guide projection 25. In the upper guide surface 47 of


the delivery passage 45, the two guide projection strips 20
are provided along a moving direction of the sheet-like
connected staple S. The guide projection strip 20 is a
strip-shaped projection portion which is slightly projected
from the upper guide surface 47 toward the side of the
sheet-like connected staple S. The guide projection strip
20 reduces a contact area between the upper guide surface
47 and the sheet-like connected staple S to decrease slide
resistance in moving the sheet-like connected staple S, and
thereby the sheet-like connected staple S is smoothly drawn
forth. The notch recessed portion 32 is provided at a
position facing the horizontal wall 15 of the upper guide
surface 47 of the lower guide surface 48. The notch
recessed portion 32 is a portion which brings a feeding
pawl (feeding roller) of the stapler main body 50 into
contact with the lower surface S3 of the sheet-like
connected staple S. The sheet-like connected staple S is
drawn from the storage portion 40 by the notch recessed
portion 32, and the sheet-like connected staple S is fed to
the discharge port 46.
The backward movement preventing member 31 is
projected toward the inside of the second guide passage 42,
and the leading edge 31a extends to a neighborhood of the
lower surface 13a of the curved wall 13. The backward
movement preventing member 31 can be bent due to elasticity
of the synthetic resin material. The leading edge 31a of
the backward movement preventing member 31 slides on the


lower surface S3 of the sheet-like connected staple S to
latch the connecting recess portion between the staples of
the sheet-like connected staple S, which prevents the
backward movement of the sheet-like connected staple S to
the side of the storage portion 40. The shape of the
backward movement preventing member 31 is not particularly
limited. For example, the backward movement preventing
member 31 can obliquely be provided as shown in Fig. 15A,
the backward movement preventing member 31 can be provided
in a substantially L-shape as shown in Fig. 15B, and the
backward movement preventing member 31 can be provided in a
substantially n-shape as shown in Fig. 15C. As described
above, the backward movement preventing member 31 is formed
in a pawl shape, and the leading edge 31a strongly presses
the sheet-like connected staple S (particularly drawn-forth
portion S5) against the side of the lower surface 13a of
the curved wall 13 during transportation. Therefore, there
is no possibility that the sheet-like connected staple S is
drawn from the staple refill 1 due to the excessive shock
or the like. In the case where the staple refill 1 is set,
the portion projected from the lower wall 21 is returned
into the refill, which rotates the backward movement
preventing member 31 counterclockwise. The rotation
displacement slightly retreats the leading edge 31a of the
backward movement preventing member 31 from the lower
surface 13a of the curved wall 13 to decrease the pressing
force to the sheet-like connected staple S. Therefore,


moving resistance of the sheet-like connected staple S
toward the feeding direction is decreased to perform the
staple feeding more smoothly.
The staple refill 1, in which the leading end portion
S1 of the sheet-like connected staple S is previously drawn
to the discharge port 46, is usually used. However, in the
staple refill 1 in which the leading end portion S1 is not
previously drawn from the discharge port 46, a drawing-
forth tape (not shown) provided in the leading end portion
S1 of the sheet-like connected staple S is drawn from the
discharge port 46. When the drawing-forth tape is pulled,
the sheet-like connected staple S provided in the storage
chamber 40 of the staple refill 1 is rotated and the
leading edge of the drawing-forth tape is positioned at the
discharge port 46. The staple refill 1 is attached to the
cartridge 70 which is detachably mounted to the stapler
main body 62, and the cartridge 70 is amounted to the
stapler main body 62. When the stapler main body 62 is
driven, the leading end portion S1 of the sheet-like
connected staple S is intermittently drawn toward the
driver side by feeding means (for example, feeding pawl and
feeding roller). A roll winding portion S4 of the sheet-
like connected staple S is not placed on a drawn-forth
portion S5, so that a load applied onto the feeding means
is decreased. The whole outer surfaces of the roll winding
portion S4 of the sheet-like connected staple S do not come
into contact with the inner surface of the storage chamber


(storage portion) 40, but a part. of. the roll winding
portion S4 comes into contact with the guide projection
strip 20 and/or the guide band (projection strip) 35, so
that the contact area becomes small. Therefore, frictional
resistance is reduced to further decrease the load applied
onto the feeding means.
When the leading end portion S1 of the sheet-like
connected staple S is drawn forth by feeding means 100 of
the stapler main body 62, as shown in Fig. 16A, the drawn-
forth portion S5 is brought into close contact with the
upper guide surface (the lower surface 13a of the curved
wall 13) of the delivery passage 45, and the leading edge
31a of the backward movement preventing member 31 slides
slightly on the drawn-forth portion S5 of the sheet-like
connected staple S. Therefore, the sheet-like connected
staple S can securely be delivered while little load is
applied onto the feeding means. When the leading end
portion S1 of the sheet-like connected staple S is drawn
back by a weight of the roll winding portion S4 in the
storage portion 40, as shown in Fig. 16B, the drawn-forth
portion S5 comes into close contact with one surface 26 of
the guide projection 25, and the leading edge 31a,
projected from one surface 26, of the backward movement
preventing member 31 securely latches the sheet-like
connected staple S.
In the staple refill 1, the roll winding portion S4
is decreased as the sheet-like connected staple S is drawn


forth. As shown in Fig. 16C, the sheet-like connected
staple S is delivered to the delivery passage 45 after the
drawn-forth portion S5 of the sheet-like connected staple S
is lifted by the top portion 29 of the guide projection 25,
so that the staple refill 1 also functions in the same
manner described above. The top portion 29 of the guide
projection 25 is formed in a semi-circular shape, so that
the guide projection 25 can smoothly guide the sheet-like
connected staple S.
Thus, the staple refill 1 can store the sheet-like
connected staple S wound in a roll shape in the storage
portion 40 of the refill main body 2 while the leading end
portion S1 is placed in the upper portion of the storage
portion 40, and the roll winding portion S4 is not placed
on the drawn-forth portion S5 when the sheet-like connected
staple S is fed from the discharge port 46. Therefore, the
load applied onto the feeding means is decreased.
In the conventional staple refill, a backward
movement preventing member slides on a linearly extended
portion of the sheet-like connected staple, and it is
difficult to adjust the contact pressure of the backward
movement preventing member in the slide. On the contrary,
in the staple refill 1, since the drawing-forth of the
sheet-like connected staple is caused to differ from the
drawing-back of the sheet-like connected staple in the
latching force of the backward movement preventing member
31 by utilizing the curved delivery passage 45 as described


above, the latching force of the backward movement
preventing member 31 is increased in drawing back the
sheet-like connected staple rather than in drawing forth
the sheet-like connected staple. Therefore, it is not
necessary to adjust the contact pressure of the backward
movement preventing member 31.
In the staple refill 1, similarly to the feeding
means of the stapler main body 62, the backward movement
preventing member 31 is pressed to engage the lower surface
S3 of the sheet-like connected staple S, where a bonding
agent is not applied and a bonding tape does not adhere in
a lengthwise direction. Therefore, the backward movement
of the sheet-like connected staple S can securely be
prevented, and the backward movement preventing member 31
can be arranged substantially in the center of the lower
surface S3, so that the sheet-like connected staple S can
be latched in a well-balanced manner.
In the staple refill 1, since the backward movement
preventing member 31 is integrally formed, it is not
necessary to install the backward movement preventing
member made of a metal material in the refill main body
unlike the conventional staple refill. Therefore, the
assembly of the staple refill 1 can easily be performed,
and weight reduction and cost reduction of the refill main
body 2 can be achieved. Disposal of the staple refill 1 is
easy to perform because it is not necessary to separate the
staple refill 1 into each material.


In the refill main body 2, since the opening 8 is
formed in the rear portion of the upper semi-cylindrical
wall 11 as described above, the sheet-like connected staple
S stored in the storage chamber 40 can be fixed so as not
to move during the transportation by mounting a pressing
member such as a cushion material from the opening 8 in
packaging the staple refill 1, which allow the leading edge
position of the sheet-like connected staple S not to be
shifted. In the usage of the staple refill 1, a state such
as a remaining amount of sheet-like connected staple S can
also be confirmed by utilizing the opening 8.
In the staple refill 1, the backward movement
preventing member 31 is integrated with the lower wall 21
of the lower case 5. Alternatively, as shown in Figs. 17
and 18, substantially L-shaped engaging projections 53 and
53 are formed on both sides of a plate-shaped lower wall 52
of a lower case 57, both ends of an insertion plate 56
including backward movement preventing members 55, which
are formed substantially in an inverse U-shape and
separately formed by a synthetic resin, are engaged to the
engaging projections 53 and 53, and the backward movement
preventing member 55 may be provided in the lower wall 52
of the lower case 57. The backward movement preventing
members 55 which are formed substantially in an inverse U-
shape are projected from long holes 60 formed in curved one
surface 59 of a substantially mound-shaped guide projection
58, and press the sheet-like connected staple S.


The stapler main body 62 of the stapler 61 is
attached to a motor-driven stapler, a copying machine, and
the like. As shown in Fig. 9, a cartridge storage portion
63 is formed, and the cartridge 70 is drawably provided in
the cartridge storage portion 63. Engaging recessed
portions 65 and 65 which are opened backward are formed on
both sides of the cartridge storage portion 63. Arm
members 66 and 66 biased clockwise by elastic members (not
shown) are provided on both sides of the cartridge storage
portion 63, and the engaging recessed portion 65 and 65 are
closed by leading end portions 67 and 67 of the arm members
66 and 66.
In the stapler main body 62, a forming plate and an
extruding driver are arranged in the front portion of the
cartridge storage portion 63. The forming plate forms the
linear staple located at the leading edge of the sheet-like
connected staple S in a U-shape, and the extruding driver
extrudes the staple deformed in a U-shape. A driving
device which intermittently feeds the sheet-like connected
staple S onto the driver side is provided in the lower
portion of the cartridge storage portion 63.
As shown in Figs. 1 and 2, the cartridge main body
70A of the cartridge 70 includes a bottom plate 71, a right
guide plate 72 provided in a right-end front portion of the
bottom plate 71, a right side plate 73 provided in a right-
end rear portion of the bottom plate 71, a left guide plate
75 provided in a left-end front portion of the bottom plate


71, a left side plate 76 provided in a left-end rear
portion of the bottom plate 71, a substantially U-shaped
rear plate 77 provided in the rear end of the bottom plate
71, and a substantially U-shaped front plate 79 provided in
the front end of the bottom plate 71. In the cartridge
main body 70A, the storage chamber 82 whose upper portion
is opened is formed by the bottom plate 71, the right guide
plate 72, the right side plate 73, the left guide plate 75,
the left side plate 76, the rear plate 77, and the front
plate 79.
As shown in Fig. 5, a rectangular opening 78 is
formed in the front portion of the bottom plate 71. As
shown in Fig. 3, a staple punch-out guide 80 is provided in
the front portion of the cartridge 70. A latch portion 81
which latches the front portion 2a on the side of the
discharge port 46 of the staple refill 1 is formed in the
staple punch-out guide 80.
As shown in Figs. 4 and 5, the engaging member 85
bend in a substantially U-shape and the long and thin lock
members 95 and 95 are provided in the cartridge main body
70A. The engaging member 85 includes a movable plate 86, a
left engaging plate 87 provided at the left end of the
movable plate 86, and a right engaging plate 88 provided at
the right end of the movable plate 86. Engaging
projections 89 and 89 are formed in the left engaging plate
87 and the right engaging plate 88, respectively. Latch
grooves 90 and 90 are formed on both sides of the movable


plate 86. The left engaging plate 87 is attached inside
the left side plate 76 while being rotatable by a support
shaft 91. As shown in Fig. 1, the right engaging plate 88
is attached inside the right side plate 73 while being
rotatable by the support shaft 91. The movable plate 86 is
located on the backside of the bottom plate 71, and
integrally attached to the lower ends of the left engaging
plate 87 and right engaging plate 88 which are projected
from the openings formed on the both sides of the bottom
plate 71. In the engaging member 85, the movable plate 86
is pressed by one end of each of elastic members 92 and 92,
and biased in the engaging direction (in the clockwise
direction) of the engaging projections 89 and 89.
The lock members 95 and 95 are oscillatably provided
on the both sides in the backside of the bottom plate 71 of
the cartridge main body 70A by pivots 96 and 96. In the
lock member 95, the abutting portion 97 is formed at one
end and the latch portion 98 is formed at the other end.
The abutting portion 97 emerges to the inside of the
storage chamber 82 to abut on the sheet-like connected
staple S through the through-hole 74 formed in the bottom
plate 71 in the cartridge main body 70A. The through-holes
74 and 74 are formed near the discharge port 4 6 when the
staple refill 1 is stored in the storage chamber 82, and
the through-holes 74 and 74 are formed on the both sides of
the bottom plate 71. The latch portions 98 and 98 include
latch projections 99 and 99 which can be latched in the


latch grooves 90 and 90 of the movable plate 8 6
respectively.
In the lock member '95, the side of the latch portion
98 is heavier than the side of the abutting portion 97.
The lock member 95 is biased clockwise about the pivot 96.
Accordingly, in the cartridge 70, in an initial state in
which the staple refill 1 is not stored in the storage
chamber 82, the abutting portion 97 of the lock member 95
is projected to the inside of the storage chamber 82, and
the latch projection 99 of the latch portion 98 is
separated from the latch groove 90 of the movable plate 86.
The feeding means 100 is provided in the backside of the
bottom plate 71, and the feeding means 100 includes a
feeding pawl which intermittently feeds the sheet-like
connected staple S from the opening 78. As shown in Fig.
3, a cover 83 is detachably attached to the backside of the
bottom plate 71 by fixing means such as a latch pawl and a
screw. The pivot 96 of the lock member 95 is pivoted to
the cover 83, and the other end of the elastic member 92 is
held by the cover 83.
As described above, the rear plate 77 of the
cartridge main body 70A is formed in a substantially U-
shape. As shown in Fig. 1, the rear plate 77 includes a
rear face plate 77a, a left bent plate 77b provided at the
left end of the rear face plate 77a, and a right bent plate
77c provided at the right end of the rear face plate 77a.
The left bent plate 77b is bonded to an outer surface of


the left side plate 7 6, and the right bent plate 77c is
bonded to the outer surface of the right side plate 73.
Attachment shafts 112 are formed in the upper portions of
the left bent plate 77b and right bent plate 77c, and guide
shafts 113 are provided in the lower front portions of the
attachment shafts 112.
As shown in Fig. 9, an operation lever 105 is
rotatably attached to the cartridge 70. The operation
lever 105 includes a handle portion 106 and arms 107 and
107 provided at both ends of the handle portion 106. The
lower portions of the arms 107 and 107 are rotatably
attached to the attachment shafts 112 and 112. Bent
engaging pieces 109 and 109 are integrally formed in the
lower ends of the arms 107 and 107, respectively.
Intermediate portions 111 and 111 of the arms 107 and 107
are recessed toward the inside, and the intermediate
portions 111 and 111 are latched by substantially L-shaped
latch portions 115 and 115 formed in the rear portions of
the left side plate 76 and right side plate 73,
respectively. When the arms 107 and 107 are latched by the
latch portions 115 and 115, the operation lever 105 is not
rotated clockwise.
In the cartridge 70 having the above-described
configuration, when the staple refill 1 is stored in the
storage chamber 82, the front portion 2a of the staple
refill 1 is latched by the latch portion 81. The engaging
shafts 16 and 16 of the staple refill 1 press the engaging


projections 89 and 89, formed in the left engaging plate 87
and right engaging plate 88 of the engaging member 85,
against the elasticity of the elastic members 92 and 92.
When the engaging shafts 16 and 16 climb over the engaging
projections 89 and 89, the engaging shafts 16 and 16 are
engaged by the engaging projections 89 and 89 returned to
the original positions by the elastic members 92 and 92.
Thus, the staple refill 1 is fixed in the storage chamber
82 of the cartridge main body 70A.
When the cartridge 70 is pressed into the cartridge
storage portion 63 of the stapler main body 62 as shown in
Fig. 9, the guide shafts 113 and 113 of the cartridge 70
engage the engaging recessed portions 65 and 65 while
rotating the arm members 66 and 66 counterclockwise against
the elasticity of the elastic member, and the guide shafts
113 and 113 are fixed by the engaging recessed portions 65
and 65 and the leading end portions 67 of the arm members
66 and 66 returned to the original positions. Thus, the
cartridge 70 is attached to the stapler main body 62. As
shown in Fig. 6, the engaging pieces 109 and 109 engage the
arm members 66 and 66 to be rotated counterclockwise as
shown in Fig. 6, and the operation lever 105 is held in a
substantially vertical state.
When the stapler main body 62 is driven, the sheet-
like connected staple S in the refill main body 2 is drawn
from the discharge port 46 by the feeding means 100, the
leading end portion S1 of the sheet-like connected staple S


abuts on the abutting portions 97 and 97 of the lock
members 95 and 95. The lock members 95 and 95 are rotated
counterclockwise, and the latch projections 99 and 99 of
the latch portions 98 and 98 latch the latch grooves 90 and
90 of the movable plate 86 to lock the engaging member 85.
Because the left engaging plate 87 and the right engaging
plate 88 cannot be rotated, the engaging shafts 16 and 16
of the refill main body 2 are fixed by the engaging
projections 89 and 89 formed in the left engaging plate 87
and the right engaging plate 88, and the staple refill 1
cannot be detached from the cartridge 70 in a period during
which the sheet-like connected staple S abuts on the
abutting portions 97 and 97 of the lock members 95 and 95,
i.e., in the period during which the sheet-like connected
staple S remains in the refill main body 2,.
In the case where all the' sheet-like connected
staples S are discharged from the refill main body 2, the
abutting portions 97 and 97 of the lock members 95 and 95
do not abut on the sheet-like connected staple S, so that
the abutting portions 97 and 97 of the lock members 95 and
95 are projected into the storage chamber 82 through the
through-holes 74 and 74. The lock members 95 and 95 are
rotated clockwise, and the latch projections 99 and 99 of
the latch portions 98 and 98 are separated from the latch
grooves 90 and 90 of the movable plate 8 6 to unlock the
engaging member 85. The left engaging plate 87 and the
right engaging plate 88 can be rotated against the


elasticity of the elastic member 92, so that the staple
refill 1 can be detached from the cartridge 70. In the
case where the staple refill 1 is detached from the
cartridge 70, as shown in Figs. 6 and 8, only the grip arm
18 of the staple refill 1 can be grasped to pull up the
staple refill 1 while the cartridge 70 is mounted on the
stapler main body 62. As shown in Fig. 4, when the staple
refill 1 is pulled up, the engaging shafts 16 and 16 of the
refill main body 2 press the engaging projections 89 and 89
formed in the left engaging plate 87 and right engaging
plate 88 of the engaging member 85 against the elasticity
of the elastic members 92 and 92. The staple refill 1
disengages the cartridge 70 when the engaging shafts 16 and
16 climb over the engaging projections 89 and 89. As shown
in Fig. 8, the staple refill 1 can be stored in the storage
chamber 82 of the cartridge 70 even if the cartridge 70 is
mounted on the stapler main body 62.
As described above, the staple refill 1 cannot be
detached from the cartridge 70 when the sheet-like
connected staple S remains in the refill main body 2.
However, the cartridge 70 can be taken from the stapler
main body 62. When the operation lever 105 provided in the
cartridge 70 is rotated clockwise, the engaging pieces 109
and 109 counterclockwise press down the arm members 66 and
66 against the elasticity of the elastic member to open the
engaging recessed portions 65 and 65. In this state of
things, the guide shafts 113 and 113 disengage the engaging


recessed portions 65 and 65 by pulling the operation lever
105, which allows the cartridge 70 to be taken from the
stapler main body 62.
Thus, in the cartridge 70, the engaging member 85
engages the engaging shaft 16 of the staple refill 1 when
the staple refill 1 is stored in the storage chamber 82.
When the abutting portion 97 of the lock member 95 abuts on
the sheet-like connected staple S discharged from the
discharge port 46 of the staple refill 1, the lock member
95 locks the engaging member 85 to hold the engaging state,
and the release of the staple refill 1 is prevented. When
all the sheet-like connected staples S of the staple refill
1 are discharged, since the abutting portion 97 does not
abut on the sheet-like connected staple S, the lock member
95 unlocks the engaging member 85 to enable the release of
the staple refill 1. In the cartridge 70, the staple
refill 1 cannot be detached unless all the sheet-like
connected staples S of the staple refill 1 are discharged,
so that the breakage of the sheet-like connected staple S
can be prevented. As a result, the obstacle such as the
clogging caused by the breakage can be eliminated.
[Effects of the Invention]
In the cartridge according to the invention, when the
staple refill is stored in the storage chamber, the
engaging member engages one side of the staple refill.
When the sheet-like connected staple is discharged from the
discharge port of the staple refill by the feeding means of


the stapler, because the abutting portion of the lock
member abuts on the sheet-like connected staple discharged,
the lock member locks the engaging member to hold the
engaging state of the engaging member, which prevents the
release of the staple refill. When all the sheet-like
connected staples are discharged from the staple refill,
because the abutting portion of the lock member does not
abut on the sheet-like connected staple, the lock member
unlocks the engaging member to enable the release of the
staple refill. Thus, in the cartridge according to the
invention, the staple refill cannot be detached unless all
the sheet-like connected staples are discharged from the
staple refill, so that the breakage of the sheet-like
connected staple can be prevented. As a result, the
cartridge according to the invention has the effect that
the obstacle such as the clogging caused by the breakage
can be eliminated.
In the cartridge according to the invention, the lock
member is oscillatably provided in the cartridge main body.
When one of abutting portions of the lock member emerges
into the storage chamber to abut on the sheet-like
connected staple through the through-hole formed in the
cartridge main body, the other latch portion of the lock
member oscillates in the latching direction to latch the
engaging member. When the abutting portion does not abut
on the sheet-like connected staple, the latch portion
oscillates in the unlatching direction to unlatch the


engaging member. Thus, the cartridge according to the
invention has the effect that the lock member locks the
staple refill when the lock member detects the existence of
the sheet-like connected staple while the lock member
unlocks the staple refill when the lock member does not
detect the existence of the sheet-like connected staple.
