In the case of reproduction, when the reproducing key of the key 8 is pushed, the inputs of the identification and personal code numbers are successively waited for by the microcomputer 10 similarly to the writing case, and when corresponding numbers are successively inputted by the key 7, the personal code number is collated. When it is correct, the speaking contents are reproduced. Thus, the unnecessary records are not reproduced, and the privacy of each user is protected.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to telephones.

0002

2. Description of the Related Art As telephones become more multi-functional, telephones with a recording function have appeared. That is, in a telephone having this recording function, when a recording key is pressed during a call, the call is subsequently recorded in a recorder built into the telephone. After the call, you can play the recording as many times as you like.

[0003] Therefore, with the telephone having this recording function, when taking notes during a call, for example, the user does not have to search for a memo pad or miss important matters.

0004

[Problem to be solved by the invention] However, with conventional telephones, calls are simply recorded as they are.
Problems arise when multiple users use it. For example, if Mr. A records a phone call and does not erase the recording, the next time Mr. B records, Mr. B's recording will be recorded after Mr. A's recording. Ru. Therefore, when Mr. B plays back his own recording to listen to it, Mr. A's previous recording is also played back, allowing Mr. B to listen to Mr. A's recording.

[0005] This invention attempts to solve these problems.

[0006]

[Means for Solving the Problems] Therefore, in the present invention, the reference numerals of each part correspond to the embodiments described later. A recording medium 21 and a key 7 are provided, and the recording medium 21 has the following functions:
A plurality of recording areas are provided which are divided from each other, and one of the plurality of areas is selected using a key 7, and the content of the call is recorded and reproduced in the selected recording area.

[0007]

[Operation] The content of the call is recorded in the recording area specified by the key 7 among the plurality of recording areas of the recording medium 21. Further, the contents of the call are played back from the recording area specified by the key 7.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the example shown in FIG. 1, ten users can each record one call.

In FIG. 1, 1 is a transmitter, 2 is a receiver, and 3 is a line interface. This interface 3 has a 4-wire/2-wire conversion circuit, a hook switch, etc., and is connected to an outside line L. has been done.

Further, 4 is a detection circuit for a ring tone signal at the time of incoming call, and 5 is a dial signal at the time of dialing, that is, D
A TMF signal forming circuit, 6 a switch for detecting on-hook/off-hook, 7 a dial key, 8 various operation keys, and 9 a ringer.

Furthermore, 10 is a microcomputer for system control, 11 is its CPU, 12 is a ROM in which various programs are written, and 13 is a RAM for a work area. Note that the program of the flowchart shown in FIG. 2 is also written in the ROM 12.

Further, 21 is a memory for recording telephone calls, and 23 is its memory controller. In this case, for example, as shown in FIG. 4, the memory 21 has address areas #0 to ## for recording calls for 10 people, that is, 10 calls.
It has 9. Further, the controller 23 has a microcomputer, and controls reading and writing of the memory 21 and manages its addresses by accessing command signals with the microcomputer 10.

When making a call, when the handsets 1 and 2 are removed from the telephone, the switch 6 is turned off, for example, from on, and this is detected by the microcomputer 10. Then, the microcomputer 10 puts the interface 3 into an off-hook state, and the switch circuit 33 is connected to the state shown in the figure.

When the telephone number of the other party is entered from the dial key 7, the key output is supplied to the forming circuit 5 through the microcomputer 10, and the forming circuit 5 outputs a DTMF signal corresponding to the telephone number of the other party. The DTMF signal is output to the outside line L through the interface 3. Therefore, a call and a dial have been made.

When the other party answers the call, the other party's voice signal Sr is supplied to the receiver 2 from the outside line L through the interface 3 → switch circuit 33 → amplifier 34. Also, the audio signal St from the transmitter 1 is transmitted to the amplifier 3.
1 and interface 3 to an outside line L. Therefore, you can talk to the other party.

Further, when a call is received, a ring tone signal from the outside line L is detected by the detection circuit 4, and the detection signal is supplied to the microcomputer 10.
is controlled and a ringing sound is produced.

When the handsets 1 and 2 are removed from the telephone, the switch 15 is turned from, for example, on to off, and this is detected by the microcomputer 10. As a result, the ringer 9 is stopped by the microcomputer 10, and the interface 3 is placed in an off-hook state. Further, the switch circuit 33 is also connected in the state shown in the figure. Therefore, you can talk to the other party on the phone from now on.

[0018] Furthermore, when a call is ended, when the handsets 1 and 2 are placed on the telephone, the switch 6 is turned on from off, this is detected by the microcomputer 10, and the microcomputer 10 places the interface 3 in an on-hook state. Therefore, the conversation is over.

On the other hand, during a call, the audio signal St from the amplifier 31 is supplied to the adder circuit 41, the audio signal Sr from the interface 3 is supplied to the adder circuit 41, and these added signals Si are sent to the adder circuit 41. The digital signal Si is supplied to the A/D converter 43 through A/D converter 42 for A/D conversion, and the digital signal Si is supplied to the memory 21.

During such a call, when the recording key of the keys 8 is pressed, this is detected by the microcomputer 10, and the routine shown in FIG. 2 is executed from step 101 to record the call.

That is, when the processing of the microcomputer 10 starts from step 101, in step 102,
Waiting for input of identification number. This identification number is to distinguish between users in this example, since up to ten users can record calls.

Then, the user inputs, for example, a one-digit identification number N using the numeric keys of the dial key 7. Then,
The process proceeds to step 103, and in step 103, the user waits for input of a password. This password is for preventing other users from listening to a recorded call made by a certain user, and is, for example, a four-digit number, which is input using the number keys of the dial key 7. Furthermore, if this password is not required, for example, the "*" key of the dial key 7 is pressed.

Then, when the password or the "*" key is input, the process proceeds to step 104, and in this step 104, for example, as shown in FIG.
3, the personal identification number PASN input in step 103 or the code "*" is written in the area AN corresponding to the identification number N input in step 102.

Next, in step 105, a command signal instructing the start of writing (recording) and the identification number N input in step 102 are supplied from the microcomputer 10 to the controller 23.

Then, in the controller 23, as shown in FIG. 4, an address pointer PNTR is set to the first address of area #N corresponding to the identification number N among areas #0 to #9 of the memory 21. Writing is allowed.

Therefore, in the memory 21, the pointer P
The voice signal Si during the call is written starting from the first address of area #N indicated by NTR.

While this writing is being performed, the processing of the microcomputer 10 is performed from step 105 to step 1.
The process advances to step 06, and in this step 106, the input of the recording end key among the keys 8 is awaited. Therefore, the current call continues to be recorded in memory 21 until the recording end key is pressed.

When the recording end key is pressed, the process proceeds to step 107, where the microcomputer 10 supplies the controller 23 with a command signal to end the recording, and the controller 23 prohibits writing of the recording into the memory 21. Address E of memory 21 at the end of this recording
NDN is supplied from the controller 23 to the microcomputer 10. Then, this end address ENDN is
As shown in FIG. 5 in step 08, the data is written in the area AN corresponding to the identification number N of the RAM 13, and the process ends in step 109.

In this way, when the recording key of the keys 8 is pressed during a call, the contents of the call at that time are recorded in the memory 21.

[0030] Also, when you are not talking (handset 1,
2 is in the on-hook state), when the memo recording key of keys 8 is pressed, the routine shown in FIG. .

FIG. 3 shows an example of a processing routine of the microcomputer 10 when reproducing a telephone conversation recorded in the memory 21.

That is, when the playback key of the keys 8 is pressed, the processing of the microcomputer 10 starts from step 111. In step 112, the switch circuit 33 is connected in the opposite direction to the diagram, and then in step 113, the identification You will be waiting for your number to be entered.

Then, enter the identification number N by dial key 7.
, then in step 114 the RAM
It is checked whether the data written in the area AN corresponding to the identification number N of No. 13 is a password or a code of "*".

If it is a PIN number, the process proceeds to step 115, and in step 115, the system waits for input of the PIN number, and the PIN number is entered on the dial key 7.
, the password entered in step 115 is compared with the password written in the area AN corresponding to the identification number N of the RAM 13 in step 116.

[0035] When the correct password is input, the process proceeds to step 117, and this step 11
7, the command signal instructing the start of reading (playback), the identification number N, and the end address ENDN are
It is supplied from the microcomputer 10 to the controller 23.

Then, in the controller 23, as shown in FIG. 4, an address pointer PNTR is set to the first address of area #N corresponding to the identification number N among areas #0 to #9 of the memory 21. , reading is permitted.

Therefore, from the start address of area #N of the memory 21, the audio signal Si written during the call is
is read out.

[0038] Then, this read audio signal Si
is supplied from the memory 21 to the D/A converter 51 and converted into an analog audio signal Si.
is supplied to the receiver 2 through the signal line of the amplifier 52 → switch circuit 33 → amplifier 34.

[0039] Therefore, the audio signal S recorded during the call
i, that is, the other party's audio signal Sr and one's own audio signal St can be heard.

During this playback, the memory controller 23 checks the read address of the memory 21, and when the read address reaches the end address ENDN, it stops reading the memory 21 and ends the read. Microcontroller 1 sends a command signal indicating that
Supply to 0.

Then, the command signal for ending the reading is detected in step 118, the switch circuit 33 is connected to the state shown in FIG. 1 in step 119, and the playback routine is ended in step 121.

Note that in step 114, RAM1
When the data written in the area AN corresponding to the identification number N of 3 is a code of "*", the process proceeds from step 114 to step 117, and reproduction is performed without inputting the password.

If it is determined in step 116 that the password entered in step 115 is incorrect, the process proceeds from step 116 to step 119, and no reproduction is performed.

[0044] Thus, according to the present invention, call recording areas are assigned to each of a plurality of users, so that, for example, when Mr. B plays back his own recording, Mr. B's The previous recording of Mr. A will not be played back, and each person's privacy can be protected. Or you don't have to play unnecessary recordings.

Furthermore, if a password is set when recording a call, the recorded content can be played back only when the correct password is entered, so privacy can be protected from this point as well.

Furthermore, when recording calls, it is possible to classify and record them by purpose or usage.

[0047] In the above description, each user can record one call, but if each user is allowed to record multiple calls, then And what is necessary is just to do as shown in FIG.

That is, in this case, for all areas A1 to A9 of the RAM 13, in FIG.
As represented by area AN, storage areas for a plurality of sets of password numbers PASN and end addresses ENDN are prepared for one area AN.

[0049] Then, when recording a call, step 1 in Fig. 2
05, the end address ENDN of the recording of the previous call is sent from the area AN corresponding to the identification number N of the RAM 13.
is retrieved and the ending address E of this previous call recording is retrieved.
NDN, a command signal instructing to start writing (recording), and an identification number N are supplied from the microcomputer 10 to the controller 23. In addition, in the identification number N, the first
During the second recording, the address one address before the start address of area #N is supplied as the end address ENDN. Then, in the memory controller 23, writing is performed from the address next to the recording end address ENDN of the previous call supplied from the microcomputer 10, and the call at that time is recorded in the memory 13.

When the recording of the call is finished, in step 108, the ending address ENDN in the memory 21 at that time is stored in the PIN number or "*" key used at that time together with the code as shown in FIG. ,R
They are sequentially written to AM13. When playing back the call, the identification number N is input in step 113 of FIG. The system waits for the input of a number specifying whether the Then, enter the recorded number using the dial key 7.
Enter from.

Then, the process proceeds sequentially from step 123, and then proceeds to step 126 following step 116 or step 114.

[0052] Then, in this step 126, R
Among the multiple sets of data of area #N corresponding to the identification number N of AM13, the pin number (or code of "*") of the area corresponding to the recording number input in step 123 and the end address ENDN are extracted. , the extracted data and the read command signal are sent from the microcomputer 10 to the controller 2 in the next step 117.
3.

Then, in the controller 23, among the areas #0 to #9 of the memory 21, the area #N corresponding to the identification number N and corresponding to the recording number one before the recording number input in step 123 is selected. Area end address E
The address pointer PNTR is set to the next address of NDN, and reading is permitted.

Therefore, the audio signal Si written in the area corresponding to the recording number is read out and can be heard on the receiver 2.

Therefore, in this example, each user can make multiple recordings while maintaining privacy.

In the example shown in FIG. 8, it is possible to record not only the contents of a telephone call but also a so-called answering machine for each user.

That is, 22 indicates a memory for reproducing OGM (response message when the answering machine mode is set), and this memory 22 is also controlled by the controller 23 in the same way as the memory 21. Also, 61 is DTMF
It is a signal decoder.

When recording a call, the switch circuits 32 and 33 are connected to the state shown in the figure, and when playing back the switch circuit 33 is connected to the state opposite to that shown in the figure, and the call is recorded and played back in the same way as described above. will be held.

Furthermore, the recording operation as an answering machine is performed as follows by setting the answering machine recording key of the keys 8.

That is, when there is an incoming call from the outside line L, the ring tone signal is detected by the detection circuit 4, and the detection signal is supplied to the microcomputer 10. Then, a command signal is supplied from the microcomputer 10 to the controller 23, the controller 23 permits reading of the memory 22, and the OGM signal is read from the memory 22. Then, this OGM signal is supplied to the D/A converter 51 and converted into an analog signal, and this converted OG signal is
The signal M is output to the external line L through the signal line of the amplifier 52 → switch circuit 32 → interface 3.

[0061] Therefore, the person on the other end of the phone call can hear the OGM. In this case, this OGM is, for example,
``If you have a message for A, please press the ``1'' key on the dial before speaking. If you have a message for B, please press the "2" key on the dial before speaking. '', the content instructs each person to press a specific number key on the dial key.

[0062] Then, when the person on the other end of the call presses the number key on the dial key according to the OGM, the DTMF
A signal is supplied from the outside line L to the decoder 61 through the interface 3, decoded into a signal indicating the numeric key of the dial key, and this signal is supplied to the microcomputer 10.

The microcomputer 10 regards this supplied signal as the above-mentioned identification number N, and thereafter executes the processes from step 102 onward in FIG. Note that step 103
Regarding the input of the password or the "*" key, when the other party inputs it from the telephone, it is decoded by the decoder 61 and supplied to the microcomputer 10.

[0064] Then, when the other party speaks an ICM (message of message or business) after inputting the dial key,
The ICM signal is transmitted from external line L to interface 3 →
A/D through the signal line of adder circuit 41 → amplifier 42
The signal is supplied to the converter 43, converted into a digital signal, and then supplied to the memory 21. Therefore, that ICM
The signal is written into the memory 21.

[0065] Then, when the other party hangs up, this is detected by the microcomputer 10 through the interface 3,
A command signal is supplied from the microcomputer 10 to the controller 23 to stop writing to the memory 21, that is, stopping recording of the ICM. Further, at this time, the address pointer ENDN is updated as shown in FIG. 7, for example.

In addition, the playback operation as an answering machine is performed by switching the switch circuit 33 to the opposite state as shown in FIG.
This is done as described above according to the routine.

[0067] Thus, according to this example, it is possible to record and play back telephone calls, and also realize the function of an answering machine. Moreover, even in the case of this answering machine, the IC address for each person is
Since M is recorded in the area assigned to each person in the memory 21, privacy can be protected.

[0068] In the above, in step 106, it is detected that the end key is pressed and the recording is ended, but in step 105, it is detected whether or not a certain recording time has elapsed, and when it has elapsed, You may end the recording at any time. Also, a tape recorder can be used instead of the memory 21. Furthermore, instead of the transmitter 1 and the receiver 2, a microphone and a speaker exclusively for recording and reproduction may be provided.

[0069]

[Effects of the Invention] According to the present invention, since call recording areas are assigned to each of a plurality of users, for example, when Mr. B plays back his own recording, Mr. B's The previous recording of Mr. A will not be played back, and each person's privacy can be protected. Or you don't have to play unnecessary recordings.

Furthermore, if a password is set when recording a call, the recorded content can be played back only when the correct password is entered, so privacy can be protected from this point as well.

Furthermore, when recording calls, it is possible to classify and record them by purpose or usage.
