The primary side oscillates to supply power to the secondary side via the, and the main power supply 16 rises and operates.

When the PS signal is at the H level, the transistor 46 is turned off, the IN1 of the IC44 is set to the H level, and accordingly, the output port OUT1 of the IC44 is set to the L level, the FET 43 is turned off, and the oscillation on the primary side is generated. And the main power supply 16 stops operating. For example, when the hooking switch 31 is pressed during standby, an ON signal is output from the key matrix circuit 26,
The microcomputer 17 recognizes the pressing of the hooking switch 31 and sets the output OUT5 to the L level, that is, the PS signal to the L level to activate the main power supply 16, and sends the information to the CPU 2 through the serial interface sI / O.

FIGS. 5 and 6 are explanatory views showing the 7-segment clock display section of the pictographic LCD 25. Both figures show 10:20, but the "second" of each time
The parts are different from each other. That is, in FIG.
The colon ":" 62 that divides the "hour" display portion 63 and the "minute" display portion 64 is lit, but in FIG.
2 is off. In this way, by turning on or off the colon ":" 62, it is possible to recognize that the timepiece is operating at least every one second, and thus it is possible to confirm that the device body is operating by at least 1 second. It can be recognized every second.

The operation of the facsimile apparatus having the above configuration will be described. FIG. 7 is a flowchart showing a processing procedure in the standby state of the facsimile device 1. When commercial AC input is started (step S
1) First, the main power supply 16 starts up (step S
2) Initialize the microcomputer 17 (step S
Along with 3), the CPU 2 is initialized (step S
4) At the same time, charging of the secondary battery 19 is started (step S5). When the initialization of the microcomputer 17 is completed, the facsimile machine 1 is in the standby state. The secondary battery 19 is continuously charged while the standby state continues.

It is determined whether or not the charging is completed (step S6), and when the charging is completed, that is, the voltage detection circuit 2
When the output of 8 becomes H level, the IN of the microcomputer 17
13, the microcomputer 17 accordingly sets the output OUT5, that is, the PS signal to the H level to stop the operation of the main power supply 16 (step S7), and the output RE of the voltage detection circuit 60 becomes the L level accordingly. Then, the CPU 2 is reset (step S8). And
Power supply by the secondary battery 19 and the solar battery 23 is started (step S9). On the other hand, when the charging time of one hour has passed by the timer built in the microcomputer 17, the one hour is detected and the microcomputer 17 sets the output OUT5, that is, the PS signal to the H level to stop the operation of the main power supply 16. (Step S7), and accordingly the voltage detection circuit 60
The output RE becomes L level and the CPU 2 is reset (step S8).

In any case, the secondary battery 19 is charged with the surplus power of the power supplied by the solar battery 23 at this time (step S10). After that, the mode shifts to the sleep mode (step S11).

In the sleep mode, only the timer interrupt is accepted while the execution of the program is stopped. Also, in this sleep mode, the pictogram LCD

FIG. 8 shows the clock 1 in the sleep mode.
It is a flow chart which shows a processing procedure when a second timer interruption occurs. In the sleep mode of FIG. 7, when the 1-second timer interrupt for the clock occurs, the time of the clock counter is advanced by 1 second (step S21). And
The display of the "hour" display portion 63 is controlled (step S22),
The display of the "minute" display unit 64 is controlled (step S23),
The display of the colon ":" 62 is controlled (step S2).
4).

Further, discharge detection of the secondary battery 19 which will be described later is performed (step S25), and when discharge is not detected, key and document detection which will be described later are performed (step S2).
6) If no key or original is detected, off-hook detection of the handset described below is performed (step S2).
7) If no off-hook is detected, a call signal (CI signal) described later is detected (step S28),
When the call signal is not detected, the process returns to the sleep mode (step S11).

FIG. 9 is a flow chart showing the processing procedure of the display control of the colon ":" 62 in step S24 of FIG. First, it is determined whether or not the second of the clock counter is 0 second (step S31), and when the second of the clock counter is 0 second, the colon ":" 62 is turned on (step S3).
2) Return. When the second of the clock counter is not 0 second, it is determined whether or not the colon ":" 62 is lit (step S33). When the colon ":" 62 is lit, the colon ":" 62 is turned off. (Step S34) Return. On the other hand, in step S33, a colon ":" 62
When is turned off, the colon ":" 62 is turned on (step S32), and the process returns.

In this way, by turning on or off the colon ":" 62 every 1 second, it is possible to recognize that the clock is operating at least every 1 second, and the apparatus main body is operating. Can be recognized at least every 1 second.

Since the colon ":" 62 is turned on or off every second, visually accurate one second can be measured. At 0 second, the colon ":" 62 always lights up, so that the minute switching time can be easily identified. Since it is not necessary to provide a special "second" display section, the display section can be made as small as necessary.
