ABSTRACT:
A battery loading mechanism requires that a battery is inserted with a positive electrode terminal inserted first into a battery chamber. The battery chamber is formed with a space into which the battery is inserted from an insertion port opened outside. A positive-side electrical contact is provided in an inner part, opposite to the insertion port, of the battery chamber, and a negative-side electrical contact is provided on a side of the insertion port of the battery chamber. The positive-side electrode has a contact point contacting the positive electrode terminal of the battery and a preventive portion contacting the non-conductor portion when the battery is inserted with the negative electrode terminal first. The contact point does not contact the negative electrode terminal when the preventive portion contacts the non-conductor portion to reduce accidental discharge of the battery.
