Abstract

PURPOSE:To normally re-execute the program at the time of restoration of power failure by saving auxiliary storage information which is being executed on a main storage device to an auxiliary storage device in the case of service interruptin and inhibiting a power source disconnection caused by overdischarge of a battery, and thereafter, stopping the program. CONSTITUTION:At the time of disconnection of a commercial power source 11, first of all, a program is processed by feeding a battery 12 immediately, and whether the power source disconnection is caused by an instantaneous service interruption or a service interruption which is connected only for a prescribed time t6 is monitored only for a prescribed time t3, and at the time of t3>t6, it is decided to be an instantaneous service interruption, and at the time of t3<t6, it is decided to be a service interruption. Subsequently, information of an auxiliary storage device which is being executed on a main storage device is saved to the original auxiliary storage device, and prepared for stop/operation of the program. Also, in order to inhibit the power source disconnection caused by overdischarge of the battery 12, a battery feed stopping signal is outputted and feed of the battery 12 is stopped. In such a way, a breakdown of the information of the auxiliary storage device is prevented, and the program after restoration of power failure is re-executed normally.
