ABSTRACT:
A battery housing device which includes a battery housing chamber which houses a battery, and a cover for closing the battery housing chamber. The cover includes an electrically conductive plate and a spring plate. The electrically conductive plate electrically contacts either the positive electrode or the negative electrode of a battery housed in the chamber. The spring plate is secured to the cover and supports the electrically conductive plate to be movable in a direction linking the positive electrode and the negative electrode of the battery together, to compensate for movement of the battery inside the chamber. The electrically conductive plate can have a protuberance which allows the electrically conductive plate to electrically contact the positive electrode when the battery is correctly inserted into the chamber, but which will not allow the electrically conductive plate to electrically contact the negative electrode of the battery when the battery is incorrectly inserted into the chamber.
