Here, in the energy saving state, only the control circuit (slave) 38 executes control, and in the operation state, the control circuit (main) 20 mainly executes control.

The control circuit (slave) 38 turns on the energy saving LED 28 in the energy saving mode, sets the supply state of 5vS, and simultaneously detects a call signal, detects any key operation, and detects the presence of a document. When any of them is detected, + 5v, 12v, and + 24v are activated, then the supply of + 5vS is stopped, and the activation factor is notified to the main control circuit 20 via the signal line 20g.

When the energy-saving key 32 is pressed, the energy-saving state and the operation state are switched. The switching from the energy-saving state to the operation state is performed by the slave control circuit 38 as described above. Switching from the operation state to the energy saving state is performed by an instruction to shift to the energy saving mode from the main control circuit 20 via the signal line 20g.

Here, when there is memory transmission data or memory reception data, since the image data is stored in the DRAM memory circuit 18, the apparatus enters an operation state. At this time, when the shift to the energy saving state is selected by pressing the energy saving key 32, if the reception information such as the alternate reception, the forced reception, the confidential reception, etc. is stored in the DRAM memory circuit 18, the "print early" Message is displayed on the display unit (LCD) 26, and when the print operation is selected, immediately after printing, the mode is shifted to the energy saving mode.

If yes, the process proceeds to step S100 (FIG. 5); Proceed to.

In step S88, the time of the timer α is set in the timer. In step S90, it is determined whether or not the timer has timed out. If the timer has timed out, the process proceeds to step S94, and if not, the process returns to step S92.

In step S92, information on the signal line 32a is input, and it is determined whether or not the energy saving key 32 has been pressed. If so, the process proceeds to step S94, and if not, the process proceeds to step S90. In step S94, the shift to the energy saving mode is notified to the slave control circuit 38 via the signal line 20g, and in step S96, the signal line 20f
This routine is ended without displaying anything on the display unit 26 via.

On the other hand, in step S100 (FIG. 5), it is determined whether or not the time for timer memory transmission or timer broadcast transmission has come.
Then, the process proceeds to step S2, where timer memory transmission or timer broadcast transmission is executed, and if not, the process proceeds to step S104.

In step S104, it is determined whether or not alternate reception, forced memory reception, and output of confidential reception information are selected. If the selection is made, the flow advances to step S106 to perform alternate reception, forced memory reception, or confidential reception. The information is output, and if not selected, the process proceeds to step S108.
In step S108, information on the signal line 32a is input,
It is determined whether or not the energy saving key 32 has been pressed. If the key has been pressed, the process proceeds to step S110. If not, the process returns to step S100.

In step S110, the data of the timer memory transmission and the timer broadcast transmission are stored in the DRAM memory circuit 18.
Is determined, and if so, the process proceeds to step S112. If there is no information, that is, if the information of the alternate reception, the forced memory reception, or the confidential reception is present in the DRAM memory circuit 18,
Proceed to step S116 (FIG. 6).

In step S112, the display unit 26 displays the content of "immediately shift to the energy saving mode after the completion of the timer memory transmission or the timer broadcast transmission" via the signal line 20f. Here, either timer memory transmission or timer broadcast transmission may be correctly specified. In step S114, since the mode immediately shifts to the energy saving mode after the output of the timer memory transmission, the timer broadcast transmission, the substitute reception, the forced memory reception, and the confidential reception, the timer α is set to 5 seconds.

Steps S116 and S118
In FIG. 6, it is determined which information of the alternate reception, the confidential reception, and the forced memory reception is stored in the DRAM memory circuit 18.
120, the display section 26 displays "Please output the alternate reception data quickly" via the signal line 20f, and if confidential reception is being performed, the flow proceeds to step S122, and ""Please output confidential reception data quickly" is displayed on the display unit 26. If the forced memory reception is being performed, the process proceeds to step S124, and the signal line 2
