される。Next, its operation will be explained. When the main power switch (2) is open, current flows through the photodiode circuit (8) and the photodiode (9) emits light, and the capacitor (10) becomes charged, and the light emission from the photodiode (9) causes the phototransistor to Current flows through the circuit (13), and the input terminal (21) of the microcomputer (18) is at H level. When the main power switch (2) is turned on in this state, power is supplied to the remote control receiver (17) and through it to the terminal (19) of the microcomputer (18). On the other hand, when the switch (2) is closed, the photodiode circuit (8)
However, the photodiode (9) continues to emit light for a period of time determined by the CR time constant of the capacitor (10) and resistor (11). During this time, the microcomputer (1
8) is reset by supplying power to it and is in a standby state. Due to the extinction of the photodiode (9),
The phototransistor circuit (13) is also turned off and the terminal (2
1) changes from H level to L level. The microcomputer (18) detects this level change and outputs a signal for closing the sub power switch (5) to the terminal (22).
) is closed and the main body (6) is energized. In this way, the auxiliary power switch (5) is automatically turned on without operating the remote control (3) to send out the operation signal for closing the auxiliary power switch.

If an operation signal is input to the microcomputer (18) by operating the , the sub power switch (5) can be opened. Since the opening/closing operation of the main open/close switch (2) is not accompanied by the opening/closing operation, the open/close detection circuit (7) does not detect any signal and no level change occurs at the terminal (21) of the microcomputer (18). ) is never injected. That is, the sub power switch (5) is automatically closed only when the main power switch (2) is turned on, but is controlled by the remote control (3) after the main power switch (2) is turned on.
