Abstract

PROBLEM TO BE SOLVED: To simplify the taking out work of a charging battery and enhance the safety by providing, on the lid member side of an opening part provided on a body case, a part of a connecting passage for supplying a power from the pattern of a wiring board having the charging battery loaded thereon to a load. SOLUTION: A lid member 10 has a switch 11 constituting a part of a connecting passage from the pattern of a wiring board 4 having a charging battery 7 loaded thereon to a motor which is a load. To remove the charging battery 7 from an equipment, the lid member 10 is removed by holding a switch operation button 6 to pull the lid member 10 under the OFF state where the operation button 6 is protruded from the lid member 10, and the wiring board 4 is bent off along a cutting line 16, whereby the charging battery 7 can be thus taken out from a case opening part 5. Since the switch 11 is taken out together with the charging battery 8, the removing work of the charging battery 7 can be safety performed without having a danger of sparking.

Description of the Related Art In recent years, rechargeable razors and various other small electric appliances have been becoming mainstream because rechargeable batteries can be repeatedly used as a power source compared to dry batteries. Since harmful substances such as cadmium are used, it is not preferable to dispose of the entire device everywhere in terms of pollution prevention. Therefore, it is necessary to remove and collect the rechargeable battery from the inside of the device before disposal.

とができない。However, unlike dry batteries, rechargeable batteries cannot be easily removed from equipment. When using a contact terminal plate such as a coil spring or a leaf spring as in the case of a dry battery,
The contact resistance increases with the lapse of time and the rechargeable battery cannot take advantage of a large current. Therefore, it is absolutely necessary that the rechargeable battery be firmly connected and fixed to the circuit in the device by soldering or the like. In such an attached state of the rechargeable battery, the rechargeable battery cannot be removed from the device unless the soldered portion is removed or the lead wire is cut with a blade or the like.

In particular, in the case where the removal of the rechargeable battery is performed by an actual general user rather than by a service person of the device, it has been extremely difficult since no special removal jig is provided.
