PURPOSE:To prevent continuous ON/OFF operation of a power supply section by inhibiting reoperation thereof until a predetermined time elapses after stopping operation thereof for such machines as may fail through continuous ON/ OFF operation of the power supply. CONSTITUTION:The power supply controller comprises a switch 3 inserted into an AC power input circuit for a main power supply section 4, a charging circuit including a diode 9 and a resistor 10 for charging a charging/discharging capacitor connected with the main power supply section 4, and a discharging circuit including a diode 12 being connected with the charging/discharging capacitor 11 upon interruption of the the main power supply section 4, a switch 8 and a resistor 7. When a voltage is fed from the switch 8 to a voltage monitoring port and the input voltage thereto drops below a predetermined level, a microcomputer 6 delivers a control signal for turning the switch 3 ON in response to an operational signal received from a remote control light receiving section 5. |
