Abstract

PURPOSE: To prevent a mulfunction from being generated due to an instantaneous cut-off, by monitoring an elapsed time from the time when a service interruption is detected, and inhibiting the output of a power source turn-on signal when recovering the power, until a prescribed time elapses.
CONSTITUTION: The power source controlling circuit 10 of a processor 18, etc. operated by an AC input is constituted of a service interruption detecting part 11, a power source on/off part 12 and an initializing part 13. Also, a power recovery restart securing circuit 14 provided with a counter 15 for a timer measuring a prescribed time lapse after a service interruption, the battery support part and power source part 17 of the processor 18 are provided. In this state, when the power source control circuit 10 detects a service interruption by its service interruption detecting part 11, a service interruption detecting signal is sent to the power recovery restart securing circuit 14. By this securing circuit 14, in case of an instantaneous cut-off being shorter than a timer set time, the power source is turned on again to the processor 18 after the timer set time elapsed, and in case of the power recovery after the service interruption being longer than the set time, the power source is turned on again immediately.
