Abstract: PURPOSE:To have assured ON and OFF of a power supply and to avoid destruction of the stored information, by securing linkage between the open/close of a cover member for an inserting hole of an external memory unit and a ON/OFF switch of the power supply. CONSTITUTION:When a cover for the inserting hole of an external unit of a main body device is opened, a switch SW2 and then a switch SW1 are turned off in response to the opening of the cover. Thus the supply of power is cut off. Then the cover is closed after the external memory unit is loaded, and therefore the switch SW1 is turned on. Thus the power is supplied to the main body unit of a CPU, etc. Then the power supply is applied to the external memory unit by the switch SW2 which is turned on after the SW1. Therefore the power supplied to the external memory unit only when the cover is completely closed with assured loading of the memory unit. In the same way, the power supply is turned on and off automatically and assuredly also for removal of the external memory unit. This prevents destruction of the stored information of the external memory unit, etc. due to the fact that the power supply is not turned off mistakenly.
