2. Description of the Prior Art
A telephone apparatus having a memory for recording and reproducing sound signals with a protection function are known. In such a prior art telephone apparatus, it is required to input an identification code with ten-keys to reproduce the sound signal.
In a convention telephone apparatus having a recording function, when sound data recorded is played back or reproduced, a person requesting reproduction of the sound data inputs an ID code to the telephone apparatus by using ten-keys or the like, the inputted ID code is compared with an ID code of a subscriber stored in a memory of the telephone apparatus, and the telephone apparatus judges whether or not the person agrees with the subscriber. However, when an ID code inputted by a third party different from the subscriber coincidentally agrees with that of the subscriber, the sound data of the subscriber is undesirably reproduced in response to a reproduction request of the third party. Therefore, a problem arises in that the sound data of the subscriber can be reproduced by the third party without ensure subscriber's privacy. An object of the present invention is to provide, with due consideration to this problem of the conventional telephone apparatus, a telephone apparatus in which privacy of a subscriber (or operator) who records sound data is ensured.

Hereinbelow will be described a first embodiment of this invention.
Fig. 1 is a block diagram of a telephone apparatus of the first embodiment.
The telephone apparatus of the first embodiment comprises a telephone circuit 10 including a speaker 14 and a microphone 15 for providing communication between a network and an operator, a sound data conversion circuit 3 for converting sound signals from the microphone 15 and from the network to sound data and converting sound data into another sound signal reproduced by the speaker 14, a control circuit 2 comprising a microprocessor, a memory 4, a memory cord receiving unit 13 including an interface circuit 13b comprising contacts to be coupled to a memory
card 1 and a memory card detector 13a, and an operation panel 14, having a display 14a and ten-keys 14b, a recording command key 14c for receiving a recording command operation, and a reproducing command key 14d for receiving a reproducing command operation. The ten-keys 14b receives the conventional dialing operation to the telephone circuit 10.
An operator can communicate with a third party through the microphone 15, the speaker 14, the telephone circuit 10, and the network. If the operator calls the third party, the operator dials with the operation panel 14.
The memory card receiving unit 13 having a slot 13c can receive a memory card 1 having a predetermined size. That is, when the operator inserts the memory card 1 into the slot 13c, the memory card detector 13a detects the presence of the memory card 1 and the memory card 1 is coupled to the control circuit 2 through the interface circuit 13b having the contacts, so that the control circuit 2 can read an identification code 6 stored in the memory card 1. Then, the control circuit 2 registers the identification code in an identification code registering memory 7 therein if the recording operation is executed.
When the control circuit 2 receives a recording command from the operation panel 14 (recording mode), the control circuit 2 controls the sound data conversion
circuit 3, the memory 4, the telephone circuit 10 to record the sound data from the telephone circuit 10 only when the memory card 1 is inserted. Similarly, when the control circuit 2 receives a reproducing command from the operation panel 14 (reproducing mode), the control circuit 2 controls the memory 4, the sound data conversion circuit 3, and the telephone circuit 10 to reproduce the sound data from the memory 4 using the speaker 14 only when the memory card 1 is inserted.
In the recording mode, that is, the recording command is inputted when the memory card 1 is inserted, a sound signal from the microphone 15 and from the network is a/d-converted by the sound data conversion circuit 3 and the control circuit 2 stores the identification code 6 from the memory card 1 and the sound data in a data format 9 at a storing area in the memory 4. The control circuit 2 having an address control table 2a stores the top and end addresses of the storing area of the stored sound data.
In the reproducing mode, that is, the reproducing command is inputted when the memory card 1 is inserted, the sound data is read from the memory 4 with address data from the address control table 2a and the read sound data is supplied to the speaker 14 through d/a-conversion by the sound data conversion circuit 3 and the telephone circuit 10.
Fig. 2 depicts a flow chart of the first embodiment showing the operation of the control circuit 2.
The control circuit 2 checks whether the recording command is present in step s1. If there is no recording command in step s1, the control circuit 2 checks whether the reproducing command is present in step s2. If there is no reproducing command in step s2, processing returns to step s1.
If there is the recording command in step s1, the control circuit 2 checks whether there is the memory card 1 in the memory card receiving unit 13 in step s3. If there is no memory card in the memory card receiving unit 13 in step s3, the control circuit 2 informs the operator of an erroneous operation on the display 14a in step s4. If there is the memory card 1 in the memory card receiving unit 13 in step s3, the control circuit 2 reads the identification code 6 from the memory card 1 and stores the sound data in the memory 4 having the data format 9 at the storing area. That is, the sound data 9b is stored together with the identification code 6 from the memory card 1 as the Identification code 9b. In other words, the sound data 9b is stored with a correspondence with the identification code 9a. The control circuit 2 stores the top and end address in the address control table in step s6. In the following step s16, the control circuit 2 registers

the identification code 6 from the memory card 1 in the identification code registering memory 2. After steps s4 and s16 processing proceeds to step s2.
If there is the reproducing command in step s2, the control circuit 2 checks whether there is the memory card 1 in the memory card receiving unit 13 in step s7. If there is no memory card in the memory card receiving unit 13 in step s7, the control circuit 2 informs the operator of an erroneous operation on the display 14a in step s8. If there is the memory card 1 in the memory card receiving unit 13 in step s7, the control circuit 2 reads the identification code 6 from the memory card 1 and compares the read identification code 6 with the identification code 9a stored together with the desired sound data 9b in the memory 4. If the identification code 6 from the memory cared 1 agrees with the identification code 9a in the memory 4, the control circuit 2 reads the sound data 9b stored together with the identification code 9a in the memory 4 and reproduces it by the speaker 14 through the sound data conversion circuit 3 and the telephone circuit 10 in step sll. If the identification code 6 form the memory card 1 disagrees with the identification code 9a in the memory 4, the control circuit 2 informs the operator of an erroneous operation or an inhibited operation in step s12. After steps s8, sll, and s12 processing returns to
step s1.
In the first embodiment, it is inhibited to reproduce the sound data when the identification code disagrees with the registered identification code which have been registered on the recording operation.
In the above operation the identification code 6 is checked during the reproducing operation. However, this operation may be omitted. That is, after the step s9, processing directly proceeds to step sll. This means the checking operation is executed only by checking the presence of the memory card 1. In this case, it is inhibited to reproduce the sound data 9b in the memory 4 when the memory card 1 is not inserted.
In this embodiment the sound data is stored in the memory 4 via the control circuit 2. However, it is also possible to stored the sound data from the sound data conversion circuit 3 In the memory 4 directly through the DMA method.
As described above, in the telephone apparatus with recording and production functions according the first embodiment, the control circuit 2 checks whether there is the memory card 1 in the memory card receiving unit 13. Therefore, if there is no memory card in the memory card receiving unit 13, the control circuit 2 can prohibit sound data from being recorded or reproduced. Further, the control circuit 2 reads the identification code 6 from the memory card 1 in response to a reproduction command and compares the read identification code 6 with the identification code 6 stored together with the desired sound data 9b in the memory 4. Therefore, when a third party different from an operator (or subscriber) intends to reproduce the sound data 9b recorded in response to a recording command of the subscriber, the control circuit 2 can prohibit the sound data 9b from being reproduced in response to a reproduction command of the third party. Accordingly, privacy of the subscriber can be reliably ensured.
A second embodiment will be described.
The telephone apparatus of the second embodiment has substantially the same structure as that of the first embodiment. The difference is that the control circuit 2 stores the sound data in the recording mode in consideration of the space in the memory 4.
Fig.3 depicts a flow chart of the second embodiment
showing the operation of the control circuit 2.
The operation in Fig. 3 is substantially the same as that in Fig. 2. The difference is that steps s13 to s15 are added.
In the recording mode, after step s3, the control circuit 2 checks whether there is a space for recording the sound data in step s13. If there is a space for recording the sound data in step s13, processing proceeds to step s5 and reads the identification code 6 and stores the sound data with the identification code 6 as similar to the first embodiment.
In step s13, if there is no space for recording the sound data, the control circuit 2 collates the identification code 6 from the memory card 1 with the identification codes in the identification code registering memory 7. If there is an identification code in the identification code registering memory 7 agreeing the identification code from the memory card 1, the control circuit 2 reads the top and end addresses of the storing area of the sound data storing the identification code from the address control table 2a and stores the sound data from the sound data conversion circuit 3 at the detected storing area, that is, the control circuit 2 writes the new sound data over the sound data which have been written at the detected storing area.
In step s14, if there is no identification code in the identification code registering memory 7 agreeing the identification code 6 from the memory card 1, processing proceeds to step s4 to inform the user of an erroneous operation (no space in the memory 4) in step s4.
In the second embodiment, it is inhibited to write new sound data over the old sound data in the memory 4 if the identification code in the memory card 1 disagrees with the identification codes registered in the identification code registering memory 7. That is, only recording command from the person who has recorded the sound data in the memory 4 can be received.
A third embodiment will be described.
Fig. 4 is a block diagram of a telephone apparatus of the third embodiment.
The telephone apparatus of the third embodiment has substantially the same structure as that of the first embodiment. The difference is that the memory card 1 has a memory 20, the control circuit 22 has a serial interface circuit 23 for sending sound data to and receiving sound data from the memory card 1, and the memory 4 is omitted.
Moreover, an address control table 24 is generated in the memory card 1 in response to the first recording command. Then, in response to the following recording command, the address control table 24 is renewed by the

control circuit 22. Further, the reproduction command is inhibited if the identification code 6 in the memory card disagrees with any one of the identification codes which have been registered in the identification code registering memory 7.
When the control circuit 22 receives the recording command from the operation panel 14, the control circuit 22 controls the sound data conversion circuit 3, the serial interface circuit 23, the telephone circuit 10 to record the sound data from the telephone circuit 10 when the memory card 1 is inserted and there is a space in the memory card 1. Then, the identification code in the memory card 1 is read from the memory card 1 and registered in the identification code registering memory 7.
Similarly, when the control circuit 22 receives the reproducing command from the operation panel 14, the control circuit 22 controls the serial interface circuit 23, the sound data conversion circuit 3, and the telephone circuit 10 to reproduce the sound data 25 from the memory card 1 using the speaker 14 only when the memory card 1 is inserted and the identification code registered in the identification code registering memory 7 agrees with the identification code 6 from the memory card 1.
In recording mode, that is, the recording command is inputted while the memory card 1 is inserted, a sound
signal from the microphone 15 and from the network is a/d-converted by the sound data conversion circuit 3 and the control circuit 22 stores the sound data 25 in the memory 20 of the memory card 1. Then, the control circuit 22 sends and stores the top and end addresses of the storing area of the stored sound data to the memory card 1. If the following recording command comes from the memory card 1 of which identification code 6 has been registered, the control circuit reads the address control table 24 at first to renew the address control table 24.
In reproducing mode, that is, when the reproducing command is inputted while the memory card 1 is inserted and the identification code 6 in the memory card 1 has been registered in the identification code registering memory 7, the sound data is read from the memory card 1 with address data from the address control table 24 and the read sound data is supplied to speaker 14 through d/a-conversion by the sound data conversion circuit 3 and the telephone circuit 10.
Fig. 5 depicts a flow chart of the third embodiment showing the operation of the control circuit 22 in Fig. 4.
The control circuit 22 checks whether the recording command is present in step s1. If there is no recording command in step s1, the control circuit 2 checks whether the reproducing command is present in step s2. If there is
no reproducing command in step s2, processing returns to step s1.
If there is the recording command in step s1, the control circuit 22 checks whether there is the memory card 1 in the memory card receiving unit 13 in step s3. If there is no memory card in the memory card receiving unit 13 in step s3, the control circuit 22 informs the operator of an erroneous operation on the display 14a in step s4. If there is the memory card 1 in the memory card receiving unit 13 in step s3, the control circuit 22 reads the address table 24 from the memory card 1 through the serial interface circuit 23 in step s17. in step e17. In the following step s13, the control circuit 22 checks whether there is a space for recording the sound data in step s13 by checking the address control table 24. If there is a space for recording the sound data in step s13, processing proceeds to step s5 where the control circuit 22 reads the identification code 6 in the memory card 1 and stores the sound data in the memory 20 in step s26. In the following step s16, the control circuit registers the identification code 6 from the memory card 1 in the identification code registering memory 7.
In step s13, if there is no space for recording the sound data, the control circuit 22 collates the identification code 6 from the memory card 1 with the
identification codes in the identification code registering memory 7. If there is an identification code in the identification code registering memory 7 agreeing the identification code from the memory card 1, the control circuit 22 reads the top and end addresses of the storing area of the sound data storing the identification code from the address control table 24 and stores the sound data from the sound data conversion circuit 3 at the detected storing area of the memory card 1, that is, the control circuit 22 writes the new sound data over the sound data which have been written at the detected storing area of the memory card 1 in step s15.
After the steps s15 and s16, the control circuit 2 stores the top and end address in the address control table in step s18, that is, the control circuit 2 renews the address control table 24 in the memory 20 of the memory card 1 in step s18.
In step s14, if there is no identification code in the identification code registering memory 7 agreeing the identification code from the memory card 1, processing proceeds to step s4 to inform the user of an erroneous operation (no space) in step s4.
If there is the reproducing command in step s2, the control circuit 22 checks whether there is the memory card 1 in the memory card receiving unit 13 in step s7. If
there is no memory card in the memory card receiving unit 13 in step s7, the control circuit 22 informs the operator of an erroneous operation on the display 14a in step s8. If there is the memory card 1 in the memory card receiving unit 13 in step s7, the control circuit 22 reads the identification code 6 from the memory card 1 and compares the read identification codes with the identification code in the identification code registering memory 7 in step s!9. If the identification code from the memory cared 1 agrees with one of the identification codes in the identification code registering memory 7, the control circuit 22 reads the sound data in the memory card 1 and reproduces It by the speaker 14 through the serial interface circuit 23, the sound data conversion circuit 3 and the telephone circuit 10. If the identification code from the memory card 1 disagrees with any of identification codes in the identification code registering memory 7, the control circuit 22 informs the operator of an erroneous operation in step s!2. After step s8, sll, and s!2 processing returns to step si.
In the third embodiment, it is inhibited to reproduce the sound data in the memory card 1 when the memory card is not inserted. Moreover, it is inhibited to reproduce the sound data when the identification code 6 from the memory card 1 disagrees with any one of the
registered identification codes which have been registered on the recording operation, so that it is inhibited to reproduce the sound data which have been recorded in another telephone apparatus.
