2. Description of the Related Art Conventionally, there is known a wired communication system which is connected to a communication line by a wire (telephone line) and comprises other terminals including general home telephones and wired communication terminals for mutually communicating voice and data. ing. In addition, in recent years, wireless communication terminals (for example, mobile phones, PHS terminals: Personal Handy Phone System terminals, which are carried by users and which mutually communicate voice and data with other terminals including general home telephones,
Pager, PDA: Personal Digital Assistant, etc.)
And a base station that is connected to a communication line and wirelessly communicates with the wireless communication terminal, and that connects the wireless communication terminal to the communication line. In such a communication system, the communication terminal is capable of accumulating various data such as the telephone number of the other party, an address book, a schedule, memos in text / voice, and the like via the telephone network. Terminals and information (voice, voice data,
Text data, image data, etc.) can be exchanged.

By setting the answering mode when the user is absent, the above communication terminal automatically goes off-hook when an incoming call is received from the other terminal and connects the line to the other terminal. On the other hand, there is a function of transmitting a response message and recording a message message input from the partner terminal in response to the response message.

[0004]

By the way, in the above-mentioned communication terminal, if the answering mode is set in the absence recording mode, the response message stored in the non-volatile memory of the main body is automatically set when the call arrives in the absence. It is possible to send to the caller and record the message from the caller in response to the reply message in the non-volatile memory. However, in a conventional communication terminal, even if it is a response message used only by a specific user, that is, a personal response message, although it is used by its owner or a plurality of other users. Since the data is recorded in the non-volatile memory of the main body shared by the users, there are the following problems.

(A) The capacity of the recording area is immediately consumed, and there is a problem that the recording function (for example, recording time, number of recordings) is likely to be restricted. (B) If there is only one recording area in the non-volatile memory of the main unit, or if the recording area has expired, delete the user's previously used response message. , I had to record my own response message, which caused a problem of complicated operations. (C) Furthermore, if the response message already recorded is recorded by another user, it is necessary to confirm whether or not the response message may be deleted.
Furthermore, there was a problem that the procedure became complicated.

Further, the communication terminal has a function of recording, in addition to the message from the caller in the above-mentioned message recording mode, the contents of the call and a voice memo for the user himself / herself in the nonvolatile memory of the main body. ing. However,
As described above, the conventional communication terminal has the following problems because the security function for the recorded message is not taken into consideration despite being used by a plurality of users.

(D) Even a personal recorded message is reproduced by another user, and there is a problem that information is leaked. (E) In addition, since it is recorded in the non-volatile memory of the main unit that is shared by multiple users, if you forget to delete the recorded messages that are no longer needed, the recording area capacity will be consumed immediately, There is a problem that the recording function (for example, recording time, number of recordings) is likely to be restricted. (F) Furthermore, if the recorded message that has already been recorded is recorded by another user, it is necessary to confirm whether or not the recorded message can be deleted.
There was a problem that the procedure became complicated.

E-3. Recording Mode Next, in the PHS terminal 4 according to the present embodiment, depending on the recording mode, the message returned from the destination in response to the response message, the contents of the call, the voice memo, etc. are recorded as a recorded message in the EEPROM 27 of the main body. The operation when the ID chip 28 is to be removed after recording (recording function) will be described. Here, FIG. 8 and FIG. 9 are flowcharts showing an operation example of the recording mode of the PHS terminal according to the present embodiment. It is assumed that the user has recorded the above-described recording message in the EEPROM 27 of the main body before executing the flowchart shown in FIG.

(1) Processing when removing the ID chip First, in FIG. 8, in step S60, it is determined whether or not the user has used the recording function. Then, if the recording function is not used, the determination result in step S60 is "NO", the process is ended, and another process is performed. On the other hand, when the recording function is used, the determination result in step S60 is "YES", and the process proceeds to step S62. In step S62, the ID attached to the mounted ID chip 28 is stored in the recorder ID of the recorded message. Next, in step S64,
It is determined whether or not the user is removing the ID chip 28. If the ID chip 28 is not about to be removed, the determination result in step S64 is "N
"O", the process is terminated and another process is performed.

On the other hand, if the user is removing the ID chip 28, the process proceeds to step S66, and a warning sound is output. The warning sound is generated by the ringer 30. The user knows that he / she should not remove it due to the above warning sound. Next, in step S68, the display unit 2
A message for confirming to the user whether or not the recorded message may be deleted, such as "Recording deletion OK?" Next, in step S70, it is determined whether or not the instruction is to erase the recorded message. Here, if the user gives an instruction to delete the recorded message, the determination result in step S70 is "YE.
S ”, the process proceeds to step S72, the recording message is erased, and the recording device is initialized. Next, in step S86 shown in FIG. 9, the display unit 26 displays a message notifying the user that the ID chip 28 may be removed.
After that, the process is terminated and another process is performed. Therefore, in this case, the user is the EEPROM of the main body.
The recorded message recorded (stored) in 27 is deleted.

On the other hand, when the user gives an instruction to hold the recorded message, the determination result in step S70 becomes "NO", and the process proceeds to step S74. Step S7
In 4, the display unit displays a message for confirming to the user whether or not the recorded message is to be heard by another user, such as "is the content to be heard by another terminal user?". Next, in step 76, it is determined whether or not it is an instruction to let another user hear the recorded message.
Here, if the user instructs not to listen, the determination result in step S76 is "NO", the process is ended, and another process is performed. So in this case,
Only the recorder ID is attached to the recorded message.

On the other hand, if the user has instructed another user to listen, the result of the determination in step S76 is "YES", and the process proceeds to step S78 shown in FIG.
Ask them to enter the ID of the user they want to hear. Here, when the user wants to listen to a recorded message to a specific user, he / she inputs the ID, and when not wanting to limit it to a specific user, when he / she wants to listen to the recorded message to an unspecified number of users. Is a predetermined special code (or key input unit 2
2 specific key). Next, in step S80, it is determined whether or not the input ID is a specific ID, and if the specific ID is input, step S8
The determination result in 0 is “YES”, and step S8
Go to 2. In step S82, the input ID is stored as the player ID shown in FIG. 3 for the recorded message. Next, as described above, in step S86, after displaying a message notifying the user that the ID chip 28 may be removed on the display unit 26, the process is ended, and another process is performed. So in this case,
The recorded message is attached with a recorder ID and a player ID indicating a user who can reproduce the recorded message.

On the other hand, when the special code is input,
The decision result in step S80 is "NO", and the flow advances to step S84 to store a special code as the player ID shown in FIG. 3 for the recorded message. next,
As described above, in step S86, after the message notifying the user that the ID chip 28 may be removed is displayed on the display unit 26, the process is ended, and another process is performed. Therefore, in this case, the recording message is attached with the recording person ID and the special code indicating that the recording message can be reproduced by an unspecified user.

(2) Processing when mounting the ID chip Next, the operation when the user mounts the ID chip 28 on the PHS terminal 4 will be described. Here, FIG. 10 is a flowchart showing an operation example when the ID chip is mounted in the PHS terminal according to the present embodiment. First, Fig. 1
In step S90 shown in 0, it is determined whether or not the ID chip 28 is mounted. If the ID chip 28 is not mounted, the process is ended as it is, and another process is executed. On the other hand, when the ID chip 28 is attached, step S
The determination result in 90 is "YES", and step S
Proceed to 92. In step S92, the ID specifying the user (owner) of the ID chip 28 is compared with the recorder ID1 to IDn of the recording message R1 to Rn shown in FIG.

Next, in step S94, the same ID
Or not. If the IDs are not the same, it is determined that the user who recorded the sound and the user who currently wears the ID chip 28 are different people, and step S96.
Proceed to. In step S96, the ID of the ID chip 28
And the player ID 1 of the recorded messages R1 to Rn shown in FIG.
~ Compare with IDn. Next, in step S98, it is determined whether the IDs are the same or the reproducers ID1 to IDn are special codes. Then, the ID of the ID chip 28 and the player ID 1 of the recorded message R1 to Rn
~ If IDn does not match or it is not a special code,
The determination result in step S98 is "NO", and the process proceeds to step S100. In step S100, the recording message R1 stored in the EEPROM 27 of the main body is recorded.
~ Rn is made unreproducible, the process ends, and another process is performed. If the storage area of the recorded message has expired, it may be overwritable. Therefore, whether the recorder ID of the recorded message is different from the ID of the user who currently wears the ID chip 28, and the reproducer ID of the recorded message and the ID of the current user are different, or If it is also not a chord, the recorded message cannot be played.

On the other hand, as a result of comparing the ID of the ID chip 28 with the reproducer ID1 to IDn of the recorded messages R1 to Rn shown in FIG. 3, if the ID is the same or a special code, the recorded message. Judge that the user is good to hear. That is, although the user who recorded the recorded message is different from the user who currently wears the ID chip 28, the current user is the user who wants to hear the recorded message or the recorded message is unspecified. It is determined that the message is a recorded message that the person wants to hear, and the process proceeds to step S102. In step S102,
Display the number of recorded messages that can be played and recorded 2
Display in 6. Next, in step S104, it is determined whether or not the user has instructed the reproduction of the recorded message. If the reproduction has been instructed, the process proceeds to step S106 to reproduce the recorded message. On the other hand, when the reproduction is not instructed, the process is finished as it is, and another process is performed. Therefore, although the recorder ID of the recorded message is different from the ID of the user who currently wears the ID chip 28, the reproducer ID of the recorded message and the ID of the current user match, or If it is a code, it is possible to play the recorded message.

On the other hand, when the ID chip 28 is attached and the ID of the ID chip 28 and the recorder ID attached to the recorded message match, the recorded user and the current ID It is determined that the user wearing the chip 28 is the same person, and the process proceeds to step S102 described above. In step S102, the number of recordable recorded messages that can be reproduced is displayed on the display unit 26, and then in step S104, it is determined whether or not the user instructs reproduction of the recorded message. Then, if reproduction is instructed, the process proceeds to step S106, and the recorded message is reproduced. On the other hand, if reproduction is not instructed, the process is ended and another process is performed. Therefore, if the recorded person ID of the recorded message and the ID of the user who currently wears the ID chip 28 match, the recorded message can be reproduced unconditionally.

As described above, in the operation example of the recording mode described above, when the ID chip 28 is to be removed after the recording message is recorded, that is, when the user changes, the recording message processing method (storing, saving, If you want the user to set (Delete) and save it, keep the recorded user ID as the recorder ID, and if you want to ask another user, keep the user ID. As a result, the recorded message which is troubled by other users will not be leaked, and depending on the setting, the recorded message can be left as a message to other users. Since the storage area can be used efficiently, it is possible to reduce restrictions on the recording function (recording time, number of recordings, etc.). In the recording mode described above, when the user who recorded the sound does not set anything, although the setting is requested by the warning sound when the ID chip 28 is about to be removed, The recorded message may be automatically deleted by a timer. Further, although the present invention is applied to the wireless communication system in the above-described embodiments, it is needless to say that the present invention can also be applied to the wired communication system.
