Abstract
Abstract A battery accommodating structure for accommodating first and second batteries in such a way that they are fixed in its accommodating portions by two pressing plates different from each other. A moving member which allows the two different pressing plates to be detached is provided to move in response to the movement of a power switch of an appliance which uses the accommodating structure. When the moving member is located at a position where the power switch is turned on, it prevent both of the first and second batteries from being removed from the accommodating portions, but when it is located at another position where the power switch is turned off, it allows one of the first and second batteries to be removed from the corresponding accommodating portion.
