[Action]

According to the present invention, the user can change the telephone number of the automatic callee from the place where he / she is going to go by a simple key operation with the remote control, and when changing the telephone number of the automatic callee with the remote control, It is possible to confirm whether the telephone number of the automatic callee has been changed correctly.

〔Example〕

In this embodiment, the following procedure is used when changing the telephone number of the automatic call destination from the outside. In the following operation, the command signal for performing the remote control is assumed to be a touch tone signal generated by a push-pong key operation.

(1) First, an answering machine (hereinafter simply referred to as a device)
Dial the telephone number of the telephone installed at.

(2) As a result, the device receives the call and closes the line, and first, the response message is reproduced.

(3) During the reproduction of this response message, a predetermined personal identification number is transmitted by key operation. This personal identification number is represented by, for example, a three-digit number.

(4) The device detects the above-mentioned personal identification number, confirms that the user is the user himself, then enters the remote control mode, and waits for a command signal.

(5) Next, as shown in FIG. 1, for example, when the "*" and "9" keys are pressed to send the command signal for the first time, the device enters the telephone number change mode of the automatic call destination.

(6) Then, a new automatic call destination telephone number is sent to the device by key operation and stored.

(7) After the transmission of the new telephone number is completed, a second command signal "*" or "9" is transmitted to notify the completion of the transmission.

(8) Then, in order to confirm the new telephone number that has just been input, the same telephone number is again key-operated and sent.

(9) The device collates this telephone number with the previously stored telephone number, and if there is an error on the way, immediately issues an error tone (for example, pi, pi, pi, pi, pi) to the user. Inform.

(10) When this error tone is received, the operation returns to the initial state, and the operation is started by sending the command signal for the first time again.

(11) When the confirmation of the new telephone number is completed, the command signal “*” “9” is sent for the third time.

(12) As a result, the device ends the telephone number changing mode and automatically turns on the automatic call function.

(13) Next, the command waiting tone (pi, pi, pi) is emitted to enter the command signal waiting state.

When making a call from a local telephone, so-called extension, to an outside line, dial "0" in Japan and "9" in the United States before dialing the outside line telephone number. in this case,
When dialing "0" or "9", the exchange in the premises first prepares to connect to the outside line, but this preparation operation takes time. If the device is installed on the local telephone, it is necessary to set "0" or "9" at the beginning of the telephone number of the automatic call destination. At this time, call "0" or "9". It is necessary to set the pause time required for the preparatory operation between the number and the number. In this embodiment, "0" or "9"
By pressing the key operation of "#" next to, the pause time of about 4 seconds is set.

In the state of waiting for a command signal at the stage (4) or (13) of the above-mentioned series of procedures, the above “*” “9”
In addition, by sending a predetermined command signal, the device can be operated by remote control in various modes. While waiting for the command signal, press the "*" and "7" keys to turn off the automatic call function or to "*".
It is also possible to turn on the automatic calling function by operating the "8" key. As described in (12) above, the automatic call function is turned on after the telephone number is changed.

FIG. 2 shows a circuit system of a portion relating to the change of the telephone number of the automatic call destination in the answering machine.

A telephone number signal for calling a telephone, the command signal, the above-mentioned changed telephone number signal and the like are input from the telephone line terminal 1 and detected by the touch tone detecting circuit 3 through the incoming circuit 2. Based on this detection, the microcomputer 4 operates the device in a predetermined mode or stores the changed telephone number.

When making an absence recording, the voice signal of the calling party is
The tape is recorded on the tape 7 by the head 6 through the incoming circuit 2 and the recording / reproducing circuit 5. During reproduction, the reproduction signal of the tape 7 is applied to the speaker 8 through the recording / reproduction circuit 5. The recording of the response message can be performed using the microphone 9. There are two types of answering machine, one for recording the response message and the message on one common tape and the other for recording separately on the two tapes. It can be applied to any of the two types.

The microcomputer 4 can also send various signals to the caller through the dial calling circuit 11, the receiving circuit 2 and the terminal 1 based on the operation of the keyboard 10.

3 and 4 show flowcharts relating to the microcomputer 4. FIG. 3 relates to the above-mentioned automatic call destination telephone number change, and FIG. 4 relates to automatic call.

The flowchart of FIG. 3 is executed according to the procedure described in (1) to (13) above.

First, when the device is in the incoming call waiting state, it is detected in step (1) whether or not the telephone is called, and when there is an incoming call, the line is closed in step (2). Next, in step (3), the response message is reproduced and transmitted to the calling party, and the end of this response message is detected in step (4). During the reproduction of the response message, the personal identification number from the user is detected in step (5). When the personal identification number is detected, the process proceeds to step (6) to wait for a command signal. Next, in step (7), when the command signals of "*" and "9" are detected, the process proceeds to step (8) to accept the input of the telephone number for changing the automatic call destination and store it. To do. When the second command signal "*" and "9" is detected in step (9), the second telephone number input for confirmation is accepted in step (10). This telephone number and the one stored previously are collated in step (11), and if both are the same, the process proceeds to step (12). If they do not match, the procedure goes to step (13) at an incorrect time point, an error tone is sent to the calling party, and the procedure returns to step (6).

If you proceed to step (12) above, the third "*"
When the command signal of "9" is detected, step (1
After turning on the automatic call function in 4), the process returns to step (6) and waits for the next command signal.
As described above, the change of the telephone number of the automatic call destination is completed.

While waiting for the command signal in step (6),
If the command signals "*" and "9" are not detected in step (7), the process proceeds to step (15) to detect other command signals. If another command signal is detected, the mode corresponding to the command signal is set in step (16). In this case, the detection of "*" and "9" command signals and other command signals described above is performed within 30 seconds in step (17), and if no command signal is detected after 30 seconds, After releasing the line by (18), it returns to the next incoming call waiting state.

When the response message is completed in step (4), the process proceeds to step (19) and the message of the calling party is recorded. When the end of the message recording is detected in step (20), the line is released in step (21) and the next incoming call waiting state is set.

Next, when the message recording is performed, the device automatically dials the automatic call destination, and this procedure is executed according to the flowchart of FIG. In addition, steps (1), (2), (3), (4) and (19) (2 in FIG. 3 described above.
The message recording routine according to 0) and (21) substantially overlaps with the routine according to steps with the same numbers in FIG.

In Fig. 4, when the message recording is completed by the above-mentioned message recording routine and the line is opened in step (21), it is checked in step (22) whether the automatic call function of the device is ON or OFF. , OFF, return to step (1). If it is ON, proceed to step (23) to dial the set automatic call destination telephone number. This automatic call lasts up to 60 seconds. That is, step (24) (2
According to 5), if the other party answers the callee's telephone and the personal identification number is entered within 60 seconds, step (6) in FIG.
And goes to the state of waiting for a command signal. If the personal identification number is not entered within 60 seconds, the line is released in step (26) and the process returns to step (1).

In the state of waiting for the command signal, for example, when there is a command signal for message reproduction in step (15) of FIG. 3, the recorded message is reproduced and used in the next step (16). Communicated to others.

Next, in the present embodiment, the above step (2
4) In (25), if the personal identification number is not detected within 60 seconds, the call is recalled after 1 hour, and if there is no response after this recall, the automatic call for the message is stopped. I am trying to do it.

Therefore, in the incoming call waiting state of step (1) in FIG. 4, whether there is a response at the time of the first automatic calling in step (27), that is, whether or not the personal identification number is detected in step (25) above. Looking at If the personal identification number has not been detected, the step (28) is followed by 60 from the point when the line is released in the step (26).
Check to see if minutes have passed. When 60 minutes have passed, the automatic call function is turned ON or OF depending on step (29).
If it is ON, go to step (23) above and recall again.

According to the above-described embodiment, the user calls the answering machine from the place where he / she goes, sends the personal identification number and confirms that he / she is the person himself, and then presses a key such as "*" or "9". The automatic call destination change mode is set by operation, and the telephone number of the automatic call destination can be easily changed by keying and sending the telephone number to be changed next. Further, since the change is confirmed, the automatic call destination change can be surely performed. Furthermore, since the automatic calling function can be turned on / off from the place where the user is away, the automatic calling function can be appropriately used depending on the situation. Moreover, since the call is further recalled, the user can be surely informed of the requirement. It should be noted that the recalling may be performed after a predetermined time other than one hour after the initial calling, and in some cases, the recalling may be performed three times or more.

〔The invention's effect〕

According to the present invention, since the user can change the telephone number of the automatic call destination from the place where he / she is going, etc. by a simple key operation with the remote control, the range in which the user can listen to the recorded message while he / she is away is conventionally. It is possible to use the automatic calling function to the full extent.

Also, when changing the telephone number of the automatic call destination using the remote control, it is possible to confirm whether the telephone number of the automatic call destination has been changed correctly, so messages such as messages can be transferred to the wrong call destination. Therefore, it is possible to prevent the contents of the message from being listened to without permission, and further, it is possible to prevent unnecessary trouble from calling the wrong call destination.
