PROBLEM TO BE SOLVED: To achieve a thinner designing of a product by bending a tip part of a positive terminal in the diametrical direction of a battery at the tip of a battery removing member to remove the battery, facilitating the exchange of the battery while eliminating an insulation plate for the removal of the battery. SOLUTION: In the replacing of a battery, firstly, a battery lid 8 mated with a hole 7a for exchanging a lower case battery provided in a lower case 7 is taken off. Then, the tip of a battery removing member, for example, a mechanical pencil is forced into a gap on plane in the diametrical direction of a battery 6 to expand the gap until it hits the hole 7a for exchanging, so that a repulsion force of a positive terminal 3 is released as holding the side of the battery 6 being pressed thereon. The battery 6 is only under a repulsion force of a negative terminal 4 pressing the bottom of the battery 6 thereon and is lifted to be removed easily. It is desired that the repulsion force of the negative terminal 4 is set larger than the weight of the battery 6 and the repulsion force of the positive terminal 3 is set larger than the repulsion force of the negative terminal 4. |
