Abstract
A card body 2 has two battery holding sections (13, 14) inside, and two battery holders (9, 10) each containing a battery are housed therein. The two housed battery holders (9, 10) engage locking portions (22a, 22b) of a stopper (11), thereby setting them unremovable. When the stopper (11) is slid toward one battery holding section (14), the battery holder (10) therein is still kept unremovable, while the other battery holder (9) can be made removable. Thus, even during battery change, at least one battery always remains in the card body to keep supplying a backup voltage to a volatile memory.

A portable information device comprising:
- a body casing for containing a circuit board and having first and second battery insertion slots in one end thereof;
- and
- a battery holding frame arranged in an internal space of said body casing, wherein:
- said battery holding frame comprises a partitioning member, a first battery cover and a second battery cover that are integrally formed,
- said partitioning member is formed at a central portion of the battery holding frame and positioned in a boundary area between said first and second battery insertion slots of the body casing,
- said first battery cover is formed at a left-hand portion of the battery holding frame, while said second battery cover is formed at a right-hand portion of the battery holding frame,
- a locking member is arranged in the battery holding frame at a position opposing said partitioning member for keeping said first and second battery covers closed,
- bare batteries are placeable in the battery holding frame by movement in a direction perpendicular to the direction of the thickness thereof after passing through said battery insertion slots, and
- said first and second battery covers come into contact with the circumferential surfaces of the bare batteries placed in the battery holding frame when closed.
