Abstract

PURPOSE: To omit a power supply for a power supply control circuit and to simplify the power supply of a device by commonly using a power supply circuit of the power supply control circuit which controls the power supply of the device and another power supply circuit which feeds a load circuit.
CONSTITUTION: When a power supply switch 5 is turned on by an operator, a power supply circuit 1 is energized to feed a load unit 10. In such a case, a contact 51 of the switch 5 is closed and therefore a relay 6 is energized with its contact 61 turned on. While the switch 5 is turned off when the power supply is turned off and the contacts 51 and 52 of the switch 5 are opened. In such a case, however, the circuit 1 is energized as it is since the contact 61 is kept closed and feeds continuously the unit 10. A power supply control circuit 4 uses an interruption signal W for a program under execution to carry out a power supply cutting routine and to start a timer 41. The timer 41 cuts off the relay 6 after a prescribed time to turn off the circuit 1.
