機器内から充電池を取り外して回収する必要がある。2. 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.

ないため、困難極まりなかった。In addition, since it is difficult to determine from which part of the device the rechargeable battery is stored inside the device, it is necessary to break the device together when removing it, but such destruction is not an easy task. 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.

る。In the rechargeable small-sized electric device according to the present invention, a case opening is provided in a part of a main body case in which a load is stored, and at least a part of a wiring board stored in the main body case is formed in the opening. The rechargeable battery is placed facing the opening, and the rechargeable battery mounted on the wiring board is housed facing the opening with both terminals of the rechargeable battery connected and fixed to the pattern of the wiring board. It is covered with a possible lid material,
On the side of the lid member, there is provided a part 11 which constitutes a part of a connection path for supplying power of the rechargeable battery to the load from the pattern of the wiring substrate. and component 11, in contact when mounting the lid to the case opening portion 5, to supply electric power of the rechargeable battery to the load
The wiring board and the cover material are arranged so as to face each other so that the connection path for the connection path can be energized , detached when the cover material is removed , and cut off the connection path .
