Abstract

PROBLEM TO BE SOLVED: To smoothly shift to an energy conservation mode by changing display on a display part corresponding to the kind of transmission or reception information when transmission or reception information is stored in a memory when shift to the energy conservation mode is selected. SOLUTION: In the state of conserving energy only a control circuit 38 executes control. At the time of an energy conserving mode, the circuit 38 turns on energy conservation LED 28 and sets the state of supplying 5VS and at the same time detects a calling signal, some key operation and the existence of an original. At the time of detecting one of these, the circuit 38 starts +5V, +12V and +24V, stops the supply of +5VS after then and informs a main circuit 20 of a starting factor through a signal wire 20g. When an energy conservation key 32 is depressed, the similar operation is given but at the time of shifting to an operating state LED 28 is turned off. In addition three minutes after shifting instruction to the energy conserving mode is given through the signal wire 20g in the operating state, +5VS is started. After then the supply of +5V, +12V and +24V are stopped and LED 28 is turned on.

Here, when there is the memory transmission data or the memory reception data, the image data is stored in the DRAM memory circuit 18, and therefore the operation state is set. At this time, when the shift to the energy-saving state is selected by pressing the energy-saving key 32, if the DRAM memory circuit 18 stores reception information such as substitute reception, forced reception, and confidential reception, "quick print When the print operation is selected, the message "I want you to do" is displayed on the display unit (LCD) 26, and immediately after printing, the mode shifts to the energy saving mode.

In step S86, timer memory transmission, memory reception, etc. are performed in step S82 to determine whether the DRAM memory circuit 18 has information. If yes, the process proceeds to step S100 (FIG. 5), and if not, step S88. Go to.

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

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

On the other hand, in step S100 (FIG. 5), it is judged whether or not the time for timer memory transmission or timer broadcast transmission has come, and when that time comes, step S10
2, the timer memory transmission or the timer broadcast transmission is executed, and if it is not that time, the routine proceeds to step S104.

In step S104, it is determined whether the proxy reception, the forced memory reception, or the output of confidential reception information is selected. If selected, the process proceeds to step S106 to perform the proxy reception, the forced memory reception, or the confidential reception. Information is output and if not selected, the process proceeds to step S108.
In step S108, the information of the signal line 32a is input,
It is determined whether or not the energy saving key 32 is pressed. If the energy saving key 32 is pressed, the process proceeds to step S110, and if not, the process returns to step S100.

In step S110, the data of the timer memory transmission and the timer broadcast transmission is the DRAM memory circuit 18
If there is information in the DRAM memory circuit 18, that is, if there is information on alternate reception, forced memory reception, or confidential reception, the processing proceeds to step S112.
Proceed to step S116 (FIG. 6).

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

Steps S116 and S118
In FIG. 6, it is determined which information of the proxy reception, confidential reception, and forced memory reception is stored in the DRAM memory circuit 18, and if the proxy reception is performed, step S is performed.
In step 120, "Please output the proxy reception data as soon as possible" is displayed on the display unit 26 via the signal line 20f. If confidential reception is being performed, the process proceeds to step S122, and in the signal line 20f " If the forced memory reception is being performed, the content of "Please output confidential reception data as soon as possible" is displayed.
The content of "Please output the forced memory reception data early" is displayed on the display unit 26 via 0f.

As described above, according to the above embodiment, when the shift from the operation mode to the energy saving mode is selected,
