Next, the operation of this embodiment configured as described above will be described. FIG. 2 is a general flow chart showing an outline of the operation of this embodiment, and FIG. 3 is a flow chart showing in detail the pager call processing (step S16) in FIG. First, there is a call and the incoming call detection circuit 3
When this is detected and a detection signal is sent, it is determined in step S1 whether or not the recording mode is set. When it is set, a signal is sent to the switch circuit 7 via the OR circuit 6. The switch circuit 7 is turned off for a very short time and an off-hook signal is sent to the exchange (step S2). After that, in step S3, the transfer destination memory 1
The transfer destination is determined from the stored contents of 9. That is, it is determined whether or not the transfer destination telephone number or pager calling number is stored in the transfer destination memory 19 (if the telephone number and the pager calling number are determined, the pager calling number is determined. Since the first half of the number is a fixed number that calls the relay station of the service company, this is done depending on the presence or absence of this number.) When the telephone number is stored, the transfer destination is the telephone of that telephone number. If the pager's calling number is stored, it is determined that the transfer destination is the pager with the calling number, and if nothing is stored, it is determined that there is no instruction from the transfer destination. Then, a predetermined signal is sent to the response message storage unit 14 in accordance with the result of the judgment, a predetermined response message is sent to the speech circuit 8, and a corresponding voice signal is output from the speech circuit 8 to the telephone line side ( Steps S4 to S6).
That is, when the transfer destination is a telephone or pager, the response message (1) is sent in step S4 or step S5, respectively.
Alternatively, if (2) or the transfer destination is not designated, the response message (3) is transmitted from the response message storage section 14 to the speech circuit 8 in step S6. The response messages (1) and (3) are "I am absent now. If you hear a beep, please tell me what you need." And the response message (2) is "I am absent now. If you hear a beep, please tell us what you need. If you are in a hurry, please enter your home telephone number with the push button and press the # mark button at the end. " When any one of the above steps S4 to S6 is completed, a signal is sent to the recording unit 13 so that the telephone line, the bridge rectifier circuit 4, the switch circuit 7,
The recording of the voice signal sent through the speech circuit 8 is started and the timer in the control unit 1 is started to measure the elapse of a certain time (step S7). Then, after that, it is judged whether or not the DTMF signal is sent (for example, whether the other party inputs the home telephone number in response to the request of the response message (2)) (step S8), and the signal is sent. If not, it is judged whether or not there is an end signal sent from the exchange on the basis of the on-hook of the other party (step S18). If there is no end signal, the timer further finishes measuring the elapse of a certain time. It is determined (step S19), and when the predetermined time has not elapsed, the operation of returning to step S18 is repeated. When there is the above-mentioned termination signal, the process proceeds from step S18 to step S20 to stop the timer measuring operation and proceeds to step S21 to stop the recording operation of the recording unit 13 and proceeds to step S14. If the above timer measured the passage of a certain time before,
The process proceeds from step S19 to step S21, the recording stop operation is executed, and then the process proceeds to step S14. On the other hand, D
When the TMF signal is sent, the process proceeds from step S8 to step S9, the recording operation by the recording unit 13 and the elapsed time measurement operation by the timer are stopped, and the DTMF signal sent at step S10 is It is determined whether the control code is for monitoring the answering machine or the telephone number of the other party's home. Then, in the case of the former control code, the corresponding processing is performed and the operation accompanying this call is ended (step S22), but in the case of the latter telephone number, the end code (the response message (2) described above is DTMF that is sent until the code that is sent according to the operation of the desired # mark button) is sent.
The operation of sequentially storing the signal (that is, the telephone number of the other party's home) in the reception data memory 18 is repeated (steps S11 and S12).

When the end code is sent, the process proceeds from step S12 to step S13 and the control unit 1
The flag is set to 1 to store the fact that the receiving data memory 18 stores the telephone number of the other party's home who is in urgent business and who is seeking telephone contact. After the processing of step S13 or the processing of step S21 described above is finished, a signal is sent again to the switch circuit 7 via the OR circuit 6 to turn off the switch circuit 7 for a short time and send an on-hook signal to the exchange ( Step S14). Then, in step S15, the transfer destination is determined based on the stored contents of the transfer destination memory 19 similarly to the operation in step S3 described above, and when the transfer destination is the telephone number of the destination, the off-hook signal is transmitted in the same manner as described above. After being sent to the exchange, the telephone number is read from the transfer destination memory 19 and is converted into a corresponding DTMF signal by the DTMF signal encoder 11 and sent to the exchange through the speech circuit 8, the switch circuit 7 and the bridge rectification circuit 4, Call the phone, then recording section 1
The received message that was recorded in No. 3 is the speech circuit 8,
A telephone calling process for sending out via the switch circuit 7 and the bridge rectifying circuit 4 is executed (step S17). If the transfer destination is not stored in the transfer destination memory 19 and the transfer is not instructed in step S15, the operation of this time is ended. On the other hand, when the transfer destination is the pager receiver, the process proceeds to step S16, that is, the pager calling process in FIG. That is, in step S30, a signal is sent to the switch circuit 7 via the OR circuit 6 to send an off-hook signal to the exchange (step S30), and thereafter, the caller number of the pager to be called is read from the transfer destination memory 19, and Is converted into a DTMF signal by the DTMF signal encoder 11 and is sent to the exchange through the speech circuit 8, the switch circuit 7, and the bridge rectification circuit 4 to execute an automatic dialing process (step S31).

Thereafter, the completion of the response message prompting the input of the transmission message sent from the exchange side is waited for (step S32), but when this is completed, 1 is set to the flag in the control section 1 described above. It is determined whether or not the received data memory 18 stores the telephone number requested for telephone contact (step S3).
3). When the flag is set to 1, the telephone number is read from the reception data memory 18 and sent to the DTMF signal encoder 11 for DTMF signal.
The MF signal is made to be sent out to the telephone line side through the speech circuit 8, the switch circuit 7, and the bridge rectification circuit 4, and 0 is set in the flag in preparation for the next call (step S34). On the other hand, if it is determined in step S33 that the flag is not set to 1,
There is a telephone call during absence, and a specific code indicating that the message is recorded in the recording unit 13 is sent to the DTMF signal encoder 11, where the specific code is changed into a DTMF signal, and then the speech circuit 8 , Switch circuit 7,
The data is sent to the telephone line side via the bridge rectification circuit 4 (step S35). Step S34 or Step S3
After the processing of step 5 is completed, an on-hook signal is sent to the exchange in the same manner as described above (step S36), and the series of operations associated with the current call is completed.

The telephone number or the specific code sent to the service center of the pager as described above is wirelessly sent to the pager carried by the owner of the answering machine, and the carrier needs to make a telephone contact. Knowing that, the telephone number of the telephone number that has been sent is called or the telephone answering machine at home is called to listen to the message stored in the recording unit 13. The present invention is not limited to the above embodiments, and various modifications can be applied without departing from the present invention. For example, in the present embodiment, the received message is separately stored in the recording unit 13, and the telephone number of the contact is stored in the received data memory 18, respectively.
Both of them may be stored together in a recording unit composed of a tape or an IC. In this case, as shown in FIG. 4, when a call is made in the answering machine mode, an off-hook signal and a response message are output. (Step S4
1) The recording unit starts recording or recording all incoming data, and further starts measuring time elapsed with a timer (step S42). It continues until the time is measured, and when there is an end code, 1 is set to a predetermined flag (steps S43 to S46), after which recording and timer operations are stopped and an on-hook signal is sent (step S47). Then, the transfer operation for transferring the data of the recording section according to the transfer destination set (steps S48 to S48).
50) may be performed.
