Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery case in which a battery such as a rechargeable battery (secondary battery) made exclusively for each model can be used in both models.

[0002]

2. Description of the Related Art For example, a portable device such as a small-sized disc player capable of recording and reproducing uses a long-life lithium ion rechargeable battery (secondary battery) by simple charging once. Batteries such as rechargeable batteries used in this portable device are related to the size of the entire set of portable devices, and therefore the number of batteries adapted to the set is increasing.

[0003]

However, when a set of portable devices using a dedicated battery such as the above rechargeable battery is operated by a dry battery (primary battery), the conventional dedicated battery cannot be used. This may be put in an external battery case and connected to the above set, but when there are a plurality of types of dedicated batteries, a plurality of external battery cases are also required, resulting in a high cost.

When a battery such as a dedicated rechargeable battery is newly produced for a set of a certain model, the owner and stock of the battery can be used for other than the set unless the battery is subsequently adopted by another model. Will have no batteries. When this is used, an external battery case may be designed, but when there are a plurality of dedicated batteries, a plurality of battery cases must be designed as in the above case, resulting in high cost.

Therefore, the present invention provides a battery case in which a plurality of batteries of different sizes can be housed and used in one case body.

[0006]

[Means for Solving the Problems] A case body in which various kinds of batteries of different sizes can be stored, respectively, and a plurality of kinds of batteries which are provided at predetermined positions in the case body and come into contact with terminals of the batteries. It is provided with a connecting terminal and a guide which is provided at a predetermined position in the case body and presses each of the batteries in a predetermined direction in the case body.

[0007]

When the batteries are housed in the case body, the terminals of the batteries come into contact with the battery connection terminals provided in the case body. Further, when the batteries are housed in the case body, the batteries are pressed in a predetermined direction in the case body by the guide and do not rattle.
