Abstract: A battery storage mechanism has a plurality of holders for holding batteries. The holders has a plurality of cut sections for assisting a removal of battery. A movable switch plate is installed in the vicinity of the cut sections. The switch plate covers at least one of the cut sections, and uncovers a desired cut section by changing a position where the switch member stops. Each holder has a rib which locks the switch plate when a battery is removed from the holder. When a battery is stored in the holder, the rib comes into contact with the battery and changes the position of the rib to unlock the switch plate. If one of the batteries is removed from battery storage section, the switch plate is locked and prohibits the removal of other batteries. If this battery storage mechanism is used in an electronic device having a memory function, it is possible to prevent data in the memory from being lost by a suspension of power supply.
