Abstract: Disclosed is a battery device including a battery enclosure incorporating a battery cell. The battery device further includes an output terminal that outputs power of the battery cell. The battery enclosure includes a first surface, a second surface, a first step surface, a second step surface, a first engaging portion, a second engaging portion, a first groove, and a second groove formed in the second step surface and the second engaging portion, and a recess is provided in at least one of the first step surface and the second step surface.

Abstract: In a battery loading and unloading mechanism, a battery formed in a flat rectangular parallelepiped and having an almost square main surface is loaded and unloaded to and from a device. The battery is formed with projecting portions at longitudinal both ends of a back surface thereof and along the back surface, whereby the battery can be prevented from being erroneously inserted into the device. The projecting portion has an inclined surface acutely inclined with respect to the back surface, and when the battery is unloaded from the device, unloading of the battery from the device is accelerated by the inclined surface undergoing contact pressure of the retaining means. The device is formed with a notched portion which is adapted to expose the other projecting portion of the battery when the battery is loaded, thereby facilitating unloading of the battery.

Abstract: Provided are a pack main body of a substantially rectangular parallelepiped shape in which a battery cell is embedded, and a terminal portion provided on a front face of the pack main body. The pack main body includes bevelled portions at corner portions formed by a top face and a bottom face and opposite side faces. The terminal portion is provided, in a protruding manner, on the front face at a position biased with respect to centre lines in a width direction and a height direction. The corner portions on one side have a chamfered shape and the corner portions on the other side have a rounded shape.
