Abstract
The power-supply unit, while directing externally supplied power to the control unit and the like, accumulates an amount of power that is required by the control unit to save data from the volatile memory to the non-volatile memory. When an external power supply has started, the control unit restores data of the non-volatile memory in the volatile memory; and when the external power supply has stopped, the control unit saves data from the volatile memory to the non-volatile memory.
