There are only two types of batteries that are used separately: large and small.
There has never been a device that allows two to be selectively inserted and used in one storage case.

The present invention provides a large battery that is shaped like a rectangular parallelepiped and has a large width and height; Two types of batteries, large and small, consisting of a small battery that is smaller than the battery and a small battery that is larger than 1/2 of the height of the battery, can be selectively inserted and stored in one storage case from the depth direction. Moreover, in doing so, the dead space inside and outside the storage case can be minimized, and the partition plate used when inserting the small battery can be easily handled, and the partition plate can be prevented from being lost. It also makes it possible to prevent this.

E. Means for Solving Problems The present invention consists of a large battery that is shaped like a rectangular parallelepiped and has a large width and height; and a small battery whose height is smaller than the height of the large battery are selectively inserted and stored in one storage case from the depth direction, the storage case having a substantially convex cross section. In this storage case, there is a first battery corresponding to the width and height of the large battery.
A storage space, and a pair of left and right second storage spaces corresponding to the width and height of the small battery arranged on both left and right sides with reference to the substantially central part in the left and right direction of the first storage space, A rotatable partition plate is provided approximately at the center in the left-right direction of the first storage space to partition the pair of left and right second storage spaces, and the partition plate is locked in an upright state from a horizontal state. A lock lever is provided, and when the large battery is inserted into the storage case, it is inserted into the first storage space with the partition plate laid down horizontally, and one small battery is inserted into the first storage space. Or, when inserting and storing two pieces in the storage case, the partition plate is erected vertically and locked by the lock lever, and then inserted into the second storage space on both the left and right sides of the partition plate. A pair of left and right lock levers that lock the small battery inserted into the second storage space are provided on the upper side of the first storage space so as to be vertically movable. In this battery storage device, a pair of left and right push buttons for unlocking are arranged in a pair of left and right recesses provided at the corners of the top plate and left and right side plates of the storage case, which has a substantially convex cross section.

F Function The present invention utilizes the inside of the first storage space as effectively as possible, arranging a pair of left and right second storage spaces, and placing them in the corners between the top plate and the left and right side panels of the storage case, which are almost convex. By effectively utilizing the left and right pair of wasted recesses, a pair of left and right push buttons are arranged, and when a small battery is stored in the left and right pair of second storage spaces, the first one becomes wasted space. A pair of left and right lock levers are placed on the upper side of the storage space, so
The dead space inside and outside the storage case was minimized.

In addition, in this invention, a partition plate that partitions the left and right pair of second storage spaces is rotatably mounted inside the storage case, and a lock lever is provided for the partition plate, so that when storing a large battery, the partition plate can be held horizontally. When storing one or two small batteries at the same time, the partition plate is simply rotated vertically and locked using the lock lever, so for example, when storing large batteries, The partition plate is removed outside the storage case, and when storing a small battery, the partition plate is inserted into the storage case.Compared to the method where the partition plate is inserted and removed, the partition plate can be used to indicate when it is in use and when it is not in use. It is very easy to handle and change the operation. In addition, if the partition plate is inserted and removed, it is very easy to lose the partition plate, but if the partition plate is rotatably attached inside the storage case, there is no risk of losing the partition plate.
