Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data communication device for automatically calling a predetermined destination when a voice message or image data is communicated in response to an incoming call.

[0002]

2. Description of the Related Art Conventionally, as this type of apparatus, for example, a facsimile machine having an answering machine function and automatically calling a pre-registered destination when recording a voice message or receiving an image. The device is known. In this facsimile machine, an answering machine is connected via a network control unit (NCU). When the answering machine automatically responds to the ringing signal from the line and records the voice message of the other party, the facsimile machine detects that the answering machine has opened the line, and in response to this detection, the inside of the facsimile machine is detected in advance. Auto dial the phone number stored in. Thus, the user of the answering machine can know that a message has been input to his or her answering machine by ringing the pager by setting the auto-dial number to his or her pager number.

[0003]

However, in the above-mentioned conventional example, a user who knows that a message has been input to the answering machine by pager calling makes a call from another terminal to call the answering machine for remote control. When the line was disconnected after playing the recorded message on the answering machine, the fax machine paged again with the call. Therefore, there is a problem that the user of the answering machine will always be paged when listening to a message addressed to him / herself by remote control, although no new message is input immediately after that.

[0004]

According to the present invention, in a data communication device that automatically makes a call to a predetermined destination when data communication such as a voice message or image data is performed in response to an incoming call, the incoming call is received. By providing a means for detecting a signal for remote operation when there is, and a means for determining whether or not there is detection by the detecting means, and selecting whether to perform the automatic call operation based on the determination, for example, By selecting not to call the pager when the remote answering signal is detected while the line is being picked up after the answering machine automatically answers, it is possible to prevent the inconvenience of the pager calling after the user remotely controls the answering machine.

In step S1, the flag INHP for prohibiting pager calling is cleared, and the process proceeds to step S2.
In step S2, the DTMF signal is detected. DTMF
If no signal is detected, the process proceeds to step S3, and steps S2 to S3 are looped until the answering machine releases the line. During this time, the answering machine records a message from the other party. If the line is released without receiving the DTMF signal, the INHP flag is 0 in step S5, and thus the step S5 is executed.
Go to step 6, call the pager and return to standby.

When the other party sends a DTMF signal to remotely control the answering machine while looping through steps S2 to S3, this is detected in step S2, and the process proceeds to step S4.

In step S4, the INHP flag is set to 1 (pager call prohibition), the process returns to step S3, steps S2 to S3 are looped again, and when the line is released, the process proceeds to step S5.

In step S5, the INHP flag is tested. Since the INHP flag is 1, the pager call is not performed and the process returns to the standby.

As described above, while the answering machine is answering D
When the TMF signal is received, the pager call is not made after the line is released. Therefore, there is no inconvenience that the user of the answering machine makes a pager call caused by the call after the recorded content is reproduced by remote control from another terminal.
