Reference numeral 3 is a control circuit composed of a microprocessor, which controls each part, and 14 is a memory which stores the program of the control circuit 13, the secret code, and the telephone number data of the transfer destination. In this embodiment, the memory 14 can store three pieces of transfer destination telephone number data, but the number is not limited to this number. In addition, the personal identification number may be written in advance at the time of shipping the product, or the user may be able to write it using a ten-key pad or the like.

With these configurations, the control circuit 13 automatically dials the transfer destination when the message of interest is recorded,
If the personal identification number by the DTMF signal is input within the predetermined time, the remote mode operation is performed, and if the personal identification number is not input, the transfer operation is performed again according to the stored dial number data of the transfer destination.

The present invention will be described in more detail below.

First, a method of registering a transfer destination telephone number will be described.

With the handset 3 on hook,
The control circuit 13 writes the transfer destination telephone number in the memory 14 by inputting in the order of # → transfer destination telephone number → # → 1 to 3. At this time, the numbers 1 to 3 are the registration area destinations in the memory 14.

When the transfer destination telephone number is deleted, for example, when the transfer telephone number in the area 2 is deleted, # → # → 2
If input in this order, the control circuit 13 performs the erasing process on the memory 14.

The control circuit 13 stores in the built-in mode flag which mode of the home mode or the answering machine is set, and controls the switching circuit 11 in the home mode. The speech network circuit 1 and the handset 3 are connected. If an incoming call is detected in this mode, a bell or the like is driven to notify that there is an incoming call. When the handset 3 is off-hook, the telephone line L is closed to allow the handset 3 to talk.

In the answering machine mode, the control circuit 13 controls the switching circuit 11 to connect the speech network circuit 1 and the input / output amplifier 6. If an incoming call is detected in this answering machine, a bell or the like is driven in the same manner, but if a call is detected three times, the telephone line L is automatically closed, and the voice synthesizing circuit 9 is controlled to call a response message. It is sent to the line L. When the completion of sending the response message is detected, the recording / reproducing device 5 is driven in the recording mode. As a result, the message from the telephone line L can be recorded. Incidentally, after a predetermined time has passed, the control circuit 13 releases the telephone line L, and the recording / reproducing device 5
Drive will be stopped.

2 to 4 are flowcharts of the main program in the answering machine written in the memory 14 for operating the control circuit 13, and the operation will be described based on this.

First, in the answering machine, when an incoming call is received, the control circuit 13 automatically responds to the incoming call based on the output of the incoming call detection circuit 2, and then, in the voice synthesis circuit 9, predetermined response message data, For example, "I am absent now. Please send me a message after this" is output to the telephone line L via the speech network circuit 1 (S1-3). After that, the data from the DTMF receiver circuit 8 is monitored, and if the personal identification number data is not input, the message is recorded (S4, 5). When personal identification number data is input through the DTMF receiver circuit 8, remote control control is performed based on the data from the subsequent DTMF receiver 8 (S4, 8). For example, when 123 data is detected, the recording / playback circuit 5 is put into a playback state,
The message recorded via the input / output amplifier 6, the switching circuit 11 and the speech network circuit 1 is transferred to the telephone line L.
To send to.

When the message recording process or the remote control process is completed (in the case of the message recording process, after a predetermined time has passed from the closing of the telephone line L, in the case of the remote control process, after the completion data is detected), the control is performed. The circuit 13 releases the telephone line L (S6, 9), but in the case of the message recording process, the transfer process is performed to inform the user that the message has been recorded (S7).

In the transfer process, the control circuit 13 operates as shown in FIG.
As shown in (1), first, 1 is stored in the built-in flag n, and then it is determined whether or not the transfer telephone number is stored in the area 1 of the memory 14 (D1, 2). If not registered, area 2 and area 3 are sequentially determined, and if all are not registered, the transfer process ends (D7, D12, D1).
3).

If the transfer telephone number is stored in the area 1, the dialing process in the registration is performed (D3). In this dialing process, as shown in FIG. 4, after the telephone line L is closed, dialing is performed based on the transfer telephone number data stored in the area 1 of the memory 14 (T1,
2). When the dial transmission is completed, the control circuit 13 controls the voice synthesizing circuit 9 to send out a transfer message "Transfer. Please enter your PIN" on the telephone line L (T.
3). After this, while repeatedly transmitting the transfer message, the input of the personal identification number via the telephone line L is monitored for 40 seconds (T4). If the personal identification number is input within 40 seconds, the process proceeds to S8 in FIG. 2 and the remote control process described above is performed (T3). After this remote control process is performed, the telephone line L is released, the process returns to S1 without performing the transfer process again, and a new incoming call is detected.

If the personal identification number is not input within 40 seconds, the telephone line L is released, and the incoming and outgoing telephone numbers are monitored for change and deletion (D4, D5). If there is an incoming call, the transfer process is terminated, the process proceeds to S2 via S1, the telephone line L is closed, and then the above-described processes are performed. That is, in the absence mode, a message is recorded or a remote operation is performed when there is an incoming call. Therefore, in the former case, a new message message is recorded and the transfer process is performed again. In the latter case, the user responds to the transfer. If so, the process returns to S1 without performing the transfer process again. It should be noted here that in the present embodiment, the transfer process is terminated when there is an incoming call. However, since the caller may go on-hook before making an automatic answer, after making an automatic answer,
The transfer process may be terminated.

If the transfer telephone number is changed or deleted, the transfer process is terminated and the process proceeds to S1 to detect a new incoming call. That is, since the transfer destination is changed during the transfer process, it is not necessary to continue the transfer.

If there is no incoming call or registration change for 20 seconds, the process proceeds to D7 to determine whether or not the transfer telephone number is stored in the area 2, and if not stored, as described above, D12. If it is stored, the same processing as the transfer of the area 1 described above is performed for the transfer telephone number of the area 2 (D8 to 11).

After the transfer processing of the transfer telephone number in the area 2, D1
If the transfer telephone number is stored in the area 3 in the case of shifting to the area 2, after dialing the area 3, D1
However, if the transfer telephone number is stored in either the area 1 or the area 2 even if the transfer telephone number is not stored in the area 3, the process proceeds to D15 and the flag n is set.
Is incremented by 1 (D14 to 15). Next, the flag n is 4
If it is not 4, if it is not 4, the incoming call, the change of the registration, etc. are monitored for 30 minutes, the process returns to D2, and if it is 4, the transfer process is ended (D16 to D19). That is, if there is no reason to end the transfer process, the dial process for the areas 1 to 3 is repeated three times to end the transfer process.

As described above, the three types of transfer telephone numbers can be registered. When a user moves, if the user has registered several telephone numbers of the moving destination, each of the moving destinations can be registered. It is possible to transfer, and in recent years, there are cases where multiple types of phones such as ordinary phones and mobile phones are mixed, and multiple phone numbers may be registered by one person.Be sure to register all these phone numbers as transfer phone numbers. This is because it can be reliably transferred.

FIGS. 5 to 7 show another embodiment of the transfer processing with the pager transfer added, which will be described below.

In this process, the process in the answering machine is the same as the process shown in FIG. 2, and the telephone transfer dial process is the same as the process shown in FIGS. 3 and 4. Therefore, the description of these processes will be given here. Omit it.

The method of registering a telephone number for telephone transfer is as follows:
As described above, the input may be made in the order of # → destination telephone number → # → 1 to 3. The pager transfer telephone number may be registered in the order of * → transfer destination telephone number → * → 1 to 3.

However, in this embodiment, in addition to the transfer destination telephone number data, data indicating the mode of pager transfer or telephone transfer can be stored in each registration destination of the memory 14.

In the transfer process, the control circuit 13 sets the flag n to 1 and determines whether or not the transfer telephone number is stored in the area 1 of the memory 14 (D10).
1, 102). If the transfer telephone number is stored in the area 1, the mode of the telephone number is determined, and if it is the telephone transfer mode, the same processing as the transfer processing in the above-described embodiment is performed. In the pager transfer mode, the pager transfer is performed. Dial processing will be performed (D102 to 108).

As shown in FIG. 7, the pager transfer dial processing uses the tone transmission function of the dial transmission circuit 10 after the telephone line L is closed, dial transmission is performed according to the telephone number data in the area 1. DT corresponding to own dial number (stored in memory 14 in advance)
Send the MF signal to the telephone line L (P101-10
3). When the transmission of the DTMF signal is completed, the telephone line is released and the incoming call, the registration change, and the deletion are monitored for 10 minutes (P104 to 107). If there is an incoming call, the transfer process is terminated and the message recording process or the remote control process is performed through S1 to 4 in FIG. The transfer process is also terminated when the registration is changed. The reason for waiting 10 minutes in this way is that the owner of the pager considers the time to call after receiving.

After that, similar to the transfer process (FIG. 2) of the above-described embodiment, the above process is repeated up to three times for the transfer telephone number in each area of the memory 14 to complete the transfer process ( D109-D125).

[0036]

As described above, according to the present invention, when the DTMF signal cannot be detected after dialing the transfer destination or within a predetermined time after the end of the transfer operation, the transfer operation is restarted after the end of the transfer operation. When the DTMF signal is detected,
The transfer operation is prohibited again, and there is a high probability that the transfer destination is notified that there is a message recording.
