SUMMARY OF THE INVENTION In order to improve the above-mentioned prior art, the present invention provides a small-sized battery pack having a thickness W1 of the first dimension, which has a charging terminal on the lower surface, and a charging terminal on the lower surface. In a charging device for charging in a state where at least one of a portion having a thickness W1 having a first dimension and a large battery pack having a thickness W2 larger than the first thickness W1 is attached to a device body, , A storage unit large enough to store a large battery pack attached to the device body, a charging terminal provided at the bottom of the storage unit, and a lower portion of a reference plane perpendicular to the bottom. A first convex portion that fits into a portion having a thickness of the first dimension of a large-sized battery pack, and a second convex portion that is also provided above the reference surface and abuts against the back surface of the device body to regulate the position. Characterized by having a section That.

Further, the present invention has a small-sized battery pack having a first dimension and a thickness W1 provided with a charging terminal on the lower surface, and at least a thickness W1 having a charging terminal provided on the lower surface and having a first dimension. Part and thickness W greater than the first thickness W1
In a charging device for charging any of the large battery packs having two, a storage part having a size capable of storing the large battery pack, a charging terminal provided at the bottom of the storage part, and a charging terminal provided at the bottom. It is characterized in that it has a convex portion which is provided below the vertical reference plane and which fits into a portion having a thickness of the first dimension of a large-sized battery pack.

[0007]

When the battery pack is charged with the battery pack attached to the device body, the position of the device body is regulated by the first and second convex portions and the reference surface, and the charging is performed by the charging terminal.

When only the battery pack is charged, the position of the battery pack is regulated by the convex portion and the reference surface,
Reliable charging is performed.
