Abstract

PROBLEM TO BE SOLVED: To permit a user to easily know how many times telephone calls are made from the same calling side. SOLUTION: When an incoming call arrives in an automatic answering mode, a response is automatically made and a line with the calling side is connected. Message data which is sent is recorded in a recording medium by associating it with the telephone number Nx of the calling side. At the time of the incoming call, the number of incoming call times is counted at every telephone number Nx. When the reproduction operation of a message exists (ST31), the number of incoming call times Mx is reported at every telephone number Nx of the calling side and the message is reproduced (ST32 and ST33). When the plural messages at different time exist from the same calling side, they are continuously reproduced. Thus, the user can efficiently grasp the message without the message of the other calling side.

The telephone 10 has an operation unit 36 for the user to perform various key operations, a display unit 37 composed of a liquid crystal display element and the like, registration of telephone directory data, and a calling side in an answering machine mode. A non-volatile memory 38 used for recording a message sent from the control unit 11 and a ring tone output unit 3 for outputting a ring tone under the control of the control unit 11 when an incoming call is received.
9. The operation unit 36, the display unit 37, the non-volatile memory 38, and the ringing tone output unit 39 are connected to the control unit 11, respectively.

Here, the operation unit 36 includes a numeric keypad for inputting a telephone number and the like, a speaker key for setting a use mode of the speaker 24, an operation key for registering telephone directory data, and searching for telephone directory data. Key, an operation key for instructing a call, an operation key for setting and canceling the answering machine mode, an operation key for playing a message recorded in the answering machine mode, and the like. . The display unit 37 displays, in addition to the state of the system, the telephone directory data selected in the search of the telephone directory data, the telephone number input with the ten keys, and the like.

Next, the operation of the telephone 10 shown in FIG. 1 will be described. After the handset 25 is set to the off-hook state, or after pressing the speaker key of the operation unit 36 to close the line, the telephone number of the other party is input by operating the keys of the operation unit 36, or When a call operation is performed in a state in which the book data is searched and desired telephone directory data is displayed on the display unit 37, a call operation is performed.

That is, the changeover switch 34 is connected to the f side under the control of the control unit 11. The control unit 11 supplies a DTMF modulator 31 with a DTMF signal code corresponding to the telephone number data of the other party, and the DTMF modulator 31 outputs a DTMF signal corresponding to the telephone number data of the other party. Then, the DTMF signal is supplied to the 4-wire side (transmission) of the conversion circuit 19 through the f side of the changeover switch 34.
And transmitted to a switch (not shown) through a telephone line. As a result, the line with the other party is connected, and a call is made possible.

When a call signal is transmitted through the telephone line in a standby state, an incoming call is detected by the incoming call detecting unit 16, and a ringing tone is output from the ringing tone output unit 39 under the control of the control unit 11. Is done. Ring output section 3
While the ringing tone is being output from handset 9, handset 2
A response can be made by setting 5 to an off-hook state or pressing a speaker key of the operation unit 36. By this response operation, the hook switch 20 or the connection switch 21 is turned on, and the line is in a DC closed state. As a result, the line with the other party is connected, and a call is made possible. When the line is connected and the telephone is in a callable state, the line is disconnected by setting the handset 20 to an on-hook state or pressing a speaker key of the operation unit 36.

Next, using the flowchart of FIG.
The control operation of the control unit 11 at the time of an incoming call when the answering machine mode is set will be described.

First, in step ST11, it is determined whether there is an incoming call. If there is an incoming call, step ST12
Then, the connection switch 21 is turned on, that is, an off-hook state is answered, and the line with the calling side is connected.

Next, in step ST13, the modem circuit 1
From the output data of No. 8, the telephone number of the caller (caller number) N
x is detected, and it is determined whether or not this telephone number Nx is the first time. In this case, R is associated with the telephone number Nx of the caller.
The number of incoming calls Mx is recorded in the AM 13 or the non-volatile memory 38, and when the value is equal to or more than "1", it is determined that it is not the first time, and otherwise, it is determined that it is the first time.

If it is determined that the calling party's telephone number Nx is the first time, the RAM 13 or the non-volatile memory 3 is associated with the calling party's telephone number Nx in step ST14.
8, the number of incoming calls Mx = “1” is recorded. Then, in step ST15, a first response message for prompting transmission of the message is transmitted to the transmitting side. In this case, the switch 34 is connected to the f side, and the voice synthesizer 32 outputs the synthesized voice signal SCOMP corresponding to the first response message. The synthesized voice signal SCOMP is output via the adder 33 and the changeover switch 34. And supplies it to the conversion circuit 19. The first response message may be, for example, "Please give me a message if you hear a beep. If you don't need it, just hang up the phone."

Next, in step ST16, it is determined whether or not the line has been disconnected on the calling side based on the detection output of the line disconnection detecting unit 17, and in step ST17, a predetermined time has elapsed until a beep sound is output. It is determined whether or not. If there is a line disconnection on the calling side, the connection switch 21 is turned off, that is, on-hook state to disconnect the line with the calling side in step ST18, and thereafter, the process returns to step ST11.

When a predetermined time has elapsed without disconnecting the line on the calling side, at step ST19,
The voice synthesizing unit 32 outputs a synthesized voice signal SCOMP of a beep sound and transmits it to the transmitting side. Then, step ST20
Then, recording of a message (voice message in the present embodiment) sent from the calling side in the nonvolatile memory 38 in association with the calling party's telephone number Nx is started. At this time, the recording start time is also recorded.

Next, in step ST21, it is determined whether or not a predetermined time set in advance since the start of recording has elapsed, or whether or not a line disconnection on the transmitting side has occurred based on a detection output of the line disconnection detecting unit 17. I do. If the predetermined time has elapsed or the line on the calling side has been disconnected, step ST2
At 2, the recording is ended, and then, at step ST18, the connection switch 21 is turned off to disconnect the line with the calling side, and the process returns to step ST11.

If it is determined in step ST13 that the telephone number Nx of the caller is not the first time, the process proceeds to step S13.
At T23, the number of incoming calls Mx recorded in association with the telephone number Nx is incremented. Then, in step ST24, the telephone number N is stored in the nonvolatile memory 38.
It is determined whether there is an unplayed message recorded in association with x. When there is no unplayed message, the process proceeds to step ST15, and transmits the first response message prompting the transmitting side to transmit the message as described above, and then proceeds to step ST16. As a result, the transmitting side transmits a message to the non-volatile memory 38.
The message can be recorded in the message.

On the other hand, if there is an unplayed message recorded in association with the caller's telephone number Nx in step ST24, the caller is notified of the existence of the unplayed message in step ST25, A second response message for prompting addition is transmitted, and thereafter, the process proceeds to step ST16. As a result, the transmitting side can confirm that there is an unplayed message, and can transmit an additional message and record the message in the nonvolatile memory 38.

In this case, the changeover switch 34 is connected to the f side, and the voice synthesizer 32 outputs the synthesized voice signal SCOMP corresponding to the second response message, and the synthesized voice signal SCOMP is added to the adder 33 and the changeover switch. The signal is supplied to the conversion circuit 19 via. As the second response message, "The message at the hour and the minute has not been played yet. If there is another message, please wait after the beep. If you do not need it, hang up the phone."
And so on. By adding “○ hour ○ minute” to the second response message, the transmitting side can easily know when the recorded message has not been played back.

Next, using the flowchart of FIG.
The control operation of the control unit 11 at the time of the playback operation when the answering machine mode is set will be described.

First, in step ST31, it is determined whether or not there is a reproduction operation. If there is a reproduction operation, in step ST32, the telephone number N associated with the earliest incoming call time recorded in the RAM 13 or the non-volatile memory 38.
The number of incoming calls Mx of x is notified by voice from the speaker 24.
In this case, while the changeover switch 26 is connected to the a side,
The voice synthesizer 32 outputs a synthesized voice signal SCOMP corresponding to the number of incoming calls Mx, and supplies the synthesized voice signal SCOMP to the speaker 27 via the low-frequency amplifier 23 and the switch 26.

In this case, not only the number of incoming calls Mx but also the telephone number Nx may be notified by voice. When the telephone number Nx is registered in the telephone directory data, the telephone number Nx is registered with the telephone number Nx or the telephone number Nx.
Alternatively, the name may be notified by voice. When notifying the phone number Nx and the name by voice in this way,
The voice synthesizer 32 outputs the synthesized voice signal SCOMP corresponding to the number of incoming calls Mx and the name, and supplies the synthesized voice signal SCOMP to the speaker 27 via the low frequency amplifier 23 and the changeover switch 26.

Further, in step ST32, the message recorded in the non-volatile memory 38 is reproduced in association with the telephone number Nx of the earliest incoming time. In this case, the message reproduced from the nonvolatile memory 38 is supplied to the speaker 24 via the low frequency amplifier 23 and the changeover switch 26. Thereby, the speaker 24
Thus, a message voice is output. When there is only an incoming call and the message is not recorded, the message is not reproduced as a matter of course. In this case, a synthesized voice such as “There is no message” may be output from the speaker 24.

Since the recording start time is recorded together with the message as described above, the recording start time is indicated by the speaker 24 before or after the message is reproduced.
You will be notified by voice. Also, in the nonvolatile memory 38,
When there are a plurality of messages recorded at different times in association with the telephone number Nx, the plurality of messages are reproduced together. For example, 13:10, 1
At 4:30 and 17:10, there was a message recorded in association with the telephone number Nxa, and at 13:30 and 14:00
If there is a message recorded in association with the telephone number Nxb at 0 minutes, the message recorded in association with the telephone number Nxa is reproduced at 13:10, 14:30, 1:30
The message recorded at 7:10 is played continuously.

Next, in step ST33, it is determined whether or not there is an incoming call related to another telephone number Nx. If there is an incoming call related to another telephone number Nx, the process returns to step ST32 to notify the number of incoming calls Mx of the telephone number Nx related to the next oldest incoming time and to store the message related to the telephone number Nx in a nonvolatile manner. The data is reproduced from the memory 38. Less than,
While there is an incoming call related to another telephone number Nx, step S
The operation of T32 is repeatedly executed.

If it is determined in step ST33 that there is no incoming call related to another telephone number Nx, the process proceeds to step ST33.
Proceed to 34. In step ST34, each incoming call count Mx recorded in association with the telephone number Nx is cleared. That is, Mx = "0". Then, in step ST35, the setting of the answering machine mode is released, and in step ST36, the normal standby state is set.

In the embodiment described above,
When there is an unplayed message related to the telephone number Nx of the caller at the time of the incoming call, a second response message is transmitted to the caller and the fact is notified. Therefore, it is possible to easily confirm whether or not the message has been reproduced on the transmitting side, thereby avoiding the inconvenience of recording the same message many times.

Also, in the present embodiment, when there is a message reproducing operation, the number of incoming calls Mx is notified for each telephone number Nx of the calling side, and the user can determine how many times the same calling side has called. You can easily find out.

In the present embodiment, when there are a plurality of messages recorded at different times in association with the telephone number Nx, the plurality of messages are reproduced together. Therefore, a plurality of messages from the same sender are continuously reproduced without intervening messages from other senders, and the user can efficiently grasp the messages.

The control operation at the time of the incoming call of the telephone shown in the flowchart of FIG. 2 can be applied to the control operation at the time of the incoming call of the answering machine service center as it is.

FIG. 4 is a diagram showing a case where a call is received from a user (related to message reproduction) corresponding to the case where the control operation at the time of incoming call (related to message input) shown in the flowchart of FIG. 2 is performed.
3 shows the control operation.

First, in step ST41, it is determined whether there is an incoming call from the user. The answering machine service center determines, for example, whether or not the user is a user based on a caller number notified when a call is received. If there is an incoming call from the user, it automatically responds to the incoming call in step ST42, and then determines in step ST43 whether there is a message addressed to the user. In the description of the flowchart of FIG. 2, messages are recorded in association with the calling party's telephone numbers Nx, respectively.
In the case of an answering machine service center, a message is recorded on a recording medium for each user.

If there is a message addressed to the incoming call, the process proceeds to step ST44. This step ST4
In No. 4, a voice signal indicating the number of calls Mx of the telephone number Nx associated with the earliest incoming time is transmitted to the transmitting side, and a message recorded on the recording medium in association with the telephone number Nx is reproduced and transmitted. Send to the side. In this case, not only the number of incoming calls Mx but also a voice signal indicating the telephone number Nx may be transmitted to the transmitting side. Also, as described above, since the recording start time is recorded together with the message, an audio signal indicating the recording start time is transmitted to the user before or after reproduction of the message.

Here, when a plurality of messages recorded at different times in association with the telephone number Nx exist on the recording medium, the plurality of messages are reproduced collectively. For example, 13:10, 14:30, 17
At 10:00, there is a message recorded in association with the telephone number Nxa, and at 13:30 and 14:00, the telephone number Nxa is recorded.
When there is a message recorded in association with xb, when the message recorded in association with telephone number Nxa is reproduced, the messages recorded at 13:10, 14:30, and 17:10 are continuously reproduced. Is done.

Next, in step ST45, it is determined whether or not there is an incoming call related to another telephone number Nx. When there is an incoming call related to another telephone number Nx, the process returns to step ST44, and transmits a voice signal indicating the number of incoming calls Mx of the telephone number Nx related to the next oldest incoming call to the calling side,
The message related to the telephone number Nx is reproduced from the recording medium and transmitted to the calling side. Hereinafter, while there is an incoming call related to another telephone number Nx, the operation of step ST44 is repeatedly executed.

If it is determined in step ST45 that there is no incoming call related to another telephone number Nx, the process proceeds to step ST45.
Proceed to 46. In step ST46, the number of incoming calls Mx recorded in association with the telephone number Nx is cleared. That is, Mx = "0". Then, in step ST47, the line to the calling side is disconnected, and the process returns to step ST41.

If it is determined in step ST43 that there is no message addressed to the user associated with the incoming call, the process proceeds to step ST48.
Then, a response message indicating that there is no message is transmitted to the user. Thereafter, in step ST47, the line to the calling side is disconnected, and the process returns to step ST41.

In the above-described embodiment, an example in which a voice message is recorded has been described. However, it is needless to say that the present invention can be similarly applied to an apparatus in which a character message is recorded. Further, in the above-described embodiment, the case where the number of incoming calls Mx is notified for each telephone number Nx of the caller when there is a message playback operation has been described. , Calling party's phone number N
The number of incoming calls Mx may be reported for each x.

[0055]

According to the present invention, the number of incoming calls is counted for each telephone number of the calling side, and the number of incoming calls is reported for each telephone number of the calling side when, for example, a message is reproduced. The user can easily know how many calls have been made from the same calling side, and the convenience is improved. Further, according to the present invention, a plurality of messages recorded at different times are reproduced collectively for each telephone number of a caller, and a plurality of messages from the same caller are messages from another caller. Are continuously reproduced without any intervention, and the user can efficiently grasp the message.
