The support portion 12 is arranged in a battery storage space in the exterior body 11 in a predetermined arrangement to form storage regions respectively corresponding to three types of batteries of a single type, a single type, and an AA type. When a battery of the type corresponding to this storage area is stored in the area,
It is impossible to store batteries in other overlapping battery storage areas, so batteries can be selected from three types and used, and different types of batteries can be mixed in a series of overlapping storage areas. In addition, since different types of batteries are not connected to each other even if another type of battery is inserted into another storage area, the use of different types of batteries is prevented beforehand, and the adverse electrochemical effects of the combined use are completely prevented. Can be eliminated. Furthermore, by limiting the direction of insertion of the battery into the battery storage space only in the direction of the battery cylinder axis by the support portion 12,
After storing the battery in the corresponding storage area, the stored battery does not shift to the other storage area to which it communicates, it can be securely supported and fixed in the storage area, the storage workability is improved, and different types of batteries are mixed. Hateful.

In the battery storage section according to the embodiment, four batteries are stored.
In addition, it is also possible to adopt a configuration in which two, three, or five or more batteries are stored by changing the arrangement of each battery storage area in the battery storage space.

In the battery storage section according to the embodiment, the storage area is divided by the support section 12 after inserting a certain type of battery into the predetermined storage area, except for the storage area that directly interferes. It is configured so that another type of battery that is different from the above can be inserted into the storage area. It is also possible to arrange the support portion 12 so as to prevent interference of different types of batteries so that only batteries of the same type can be inserted, and to completely mix and store batteries of different types. This prevents any user from getting confused when inserting the batteries, and ensures that the same type of batteries can be stored and quickly put into a usable state.

Further, in the battery housing portion according to the embodiment, a battery housing space large enough to store any one of three types of batteries in a parallel arrangement is secured inside the exterior body 11, A support portion 1 that protrudes from the exterior body 11 in the battery storage space and contacts and supports each peripheral side surface of the battery.
2, the battery is inserted into or taken out of the battery storage space by moving the battery in the axial direction of the battery cylinder. However, the present invention is not limited to this, and the battery storage section 2 is formed as shown in FIG. The exterior body 21 is formed in such a manner that a plurality of three types of batteries can be inserted in a cylindrical axis direction in the internal battery storage space in a one-by-one arrangement in a cylindrical axial direction so that the battery can be stored. The battery can be integrally formed with the exterior body 21 so as to be able to make surface contact with the peripheral side surface of the battery, and as described above, after the battery is stored, the battery does not shift to another battery storage area and is securely supported in the storage area. In addition, the storage operation is excellent, and the electrical connection is not completed until all the predetermined number of batteries are stored, and the battery is not consumed due to erroneous power supply. further,
As shown in FIG. 8, an exterior body 31 forming the battery storage unit 3 is formed in a shape capable of storing a plurality of three types of batteries in series in the internal battery storage space by inserting any one of the three types of batteries from above. At the same time, the support portion 32 may be formed integrally with the exterior body 31 so as to be in surface contact with the peripheral surface of the battery along the battery storage space, and the battery can be used from a plurality of types as described above. In addition, in the battery storage state, the feature that different types of batteries are not mixed is maintained as it is, and the structure can be simplified to reduce the cost.

[0034]

As described above, according to the present invention, the support portion is provided in a predetermined arrangement so that a plurality of different types of batteries can be stored in the battery storage space, and the support portion is provided in a predetermined battery storage area of the battery storage space. When a battery of the type corresponding to this storage area is stored, it becomes impossible to store the corresponding battery in another overlapping type of battery storage area, so that the battery as a power source is not limited to one type. It can be used from multiple types, it is easy to use, and in a series of overlapping storage areas, different types of batteries can not be mixed, the same type of battery can be used exclusively, and the electrochemistry associated with the use of different types of batteries together There is an effect that the safety of the electric equipment using the battery can be ensured without being adversely affected.

According to the present invention, the battery can be inserted into and removed from the battery storage space in the cylindrical axis direction of the battery, and the direction in which the battery can be moved is limited only in the cylindrical axis direction by the support portion. After being inserted into the corresponding storage area and stored, the stored battery does not shift to another type of battery storage area that communicates, it can be securely supported and fixed in the storage area, and the battery storage even if the storage area is inclined This is advantageous in that the storage operation is excellent and that different types of batteries are less likely to be mixed in the battery storage space.

Further, according to the present invention, a plurality of storage areas for the same type of battery are arranged in parallel in the battery storage space, and the contact pieces independently disposed for each storage area are provided with predetermined wiring. Connected to each other for the same type of battery,
By using multiple batteries of the same type in series connection, even if batteries of different types are mixed and stored in the battery storage space by mistake, the contact pieces that come into contact with one type of battery are of different types. The battery is not electrically connected to the contact piece corresponding to the battery, so that different types of batteries are not electrically connected to each other, and the battery can be maintained in a safe state. In addition, since the electrical connection is not completed until a predetermined number of batteries of the same type are completely stored in the corresponding storage area, the batteries may be erroneously turned on while the batteries are being stored and may be consumed. Therefore, there is an effect that the battery can be handled more easily.
