When such a connection terminal member is momentarily separated from the pole portion of the dry battery, a so-called momentary interruption in which the power supply is momentarily interrupted occurs in the electronic device, and normal operation is continued. There is a risk that it will not be possible.

In order to prevent such a momentary disconnection, it is necessary to increase the spring constant of the leaf spring forming the connection terminal member so as to increase the pressing force of the connection terminal member against each pole portion of the dry battery. Conceivable.

However, if the spring constant of the leaf spring forming the connection terminal member is increased, it becomes difficult to insert and remove the dry battery into and from the battery storage portion, and the spring constant of the leaf spring is increased. However, it is not possible to prevent plastic deformation of the spring due to aging, so-called fatigue.

Further, in the battery housing having the connection terminal member composed of the leaf spring, so-called reverse connection in which the dry battery is housed with the direction of the anode part and the direction of the cathode part being opposite to the normal direction is prevented. Can not do it.

Therefore, the present invention is proposed in view of the above situation, and is an electronic device in which power is supplied by a battery housed in a housing, and the operation of housing and taking out the battery is easy. In addition, it is possible to provide an electronic device in which the occurrence of instantaneous interruption due to vibration or shock is prevented, the durability is good, and the reverse connection of the battery can be prevented. To aim.
