Based on this request, the facsimile circuit unit 14 performs a receiving operation of the connected FAX data via the communication line L1, and stores it in the memory (S24).

After the receiving operation is completed, the facsimile circuit unit 14 and the communication management control unit 16
The communication management control unit 16 exchanges data such as an X number, a reception date, a reception start time, a reception number, and a reception number, and stores the management data in a memory (S24). Accordingly, the communication management control unit 16 can manage the FAX data transmitted to the communication device 1.

In step S4, the power is turned off.
When the mode has shifted from the power-on mode to the power-on mode, the communication device notifies the communication management control unit 16 that the status has shifted to the power-on mode (S5).

Next, the communication device requests the communication management control section 16 to determine whether or not facsimile data for the communication device is stored in the facsimile machine 14 (S).
6) When stored, the facsimile circuit unit 1
A request is made to retransmit the data stored in No. 4 to the communication device body (S7).

The communication management control unit 16 having received this request,
Based on the management data, the facsimile circuit unit 14 is requested to transfer predetermined facsimile data stored in the memory to the communication device main body. Based on the request from the unit 16, the facsimile circuit unit 14 transfers predetermined FAX data, the communication device receives the transferred data (S9), executes a recording operation (S10), and ends the processing.

In the above embodiment, when the data transmitted through the communication line L1 is re-transferred to the communication device when the power of the communication device is turned off, an image common to the communication device and the facsimile device is used. The retransmission operation is performed via the bus. For example, the facsimile circuit unit 14 may use the communication line L2 to connect to the communication line L1, and retransmit the FAX data to the communication device.

Further, in the above embodiment, the communication management apparatus 13 has a facsimile function, but a normal facsimile is connected to a communication management apparatus having no facsimile function, and the transfer setting for this facsimile is performed. May be used, a communication device may be connected to the communication line L1 using the communication line L2, and FAX data may be transferred.

Further, in the above-described embodiment, the facsimile circuit unit 14 outputs the data without retransmitting the facsimile data to the communication device without retransmitting the facsimile data to the communication device. You may do so.

In the above embodiment, the power supply is turned off at night or on holidays.
Even in the FF state, reception of facsimile etc. is performed without any inconvenience, and the output operation can be completed at the time designated by the user, so unnecessary power consumption can be eliminated at night or on holidays, and further safety It is possible to provide a system that can ensure the performance.

[0095]

According to the present invention, even when the power is turned off at night or on holidays, a facsimile or the like can be received without any inconvenience, and the output operation can be completed at a time designated by the user. Therefore, it is possible to prevent unnecessary consumption of electric power at night or on holidays, and to ensure safety.
