Battery pack

A battery pack includes first to fifth terminal portions sequentially arrayed at one side surface of a housing, wherein the first terminal portion formed on one end side of the one side surface is a positive electrode terminal, the fifth terminal portion formed on the other end side is a negative electrode terminal, the fourth terminal portion formed adjacently to the fifth terminal portion is an ID terminal, and the fourth terminal portion and the fifth terminal portion are proximate to each other; and a guide portion for guiding the loading and unloading of the battery pack into and from a battery mounting portion is formed substantially in the center of the one side surface in array with the terminal portions, and the third terminal portion arranged centrally is formed at a position deviated toward the one end side or the other end side.

A battery pack is loaded and unloaded to and from a battery mounting portion on the electronic apparatus side by sliding a housing thereof on the battery mounting portion. A lock recess is formed in each of side surfaces adjacent to a mount surface for mounting to the battery mounting portion through a pair of side edges parallel to the sliding direction of the mount surface, and a detection recess is formed in one or each of the side surfaces according to the kind of the battery pack; and the lock recess includes an inclined surface portion, and a clamped portion to be clamped between a bottom surface of the battery mounting portion and the lock protrusion, and the thickness of the clamped portion in a height direction is set to be larger than the depth of the detection recess in the same direction.

In the present invention, there is provided a battery pack wherein a lock recess for engagement with a lock protrusion formed to protrude from the battery mounting portion side and a detection groove for engagement with a detection protrusion formed to protrude from the battery mounting portion side so as to detect the kind of the battery pack are formed in one or each of mutually opposite side surfaces adjacent to a mount surface for mounting to the battery mounting portion, according to the kind of the battery pack, and the detection groove is formed to be deeper than the lock recess in a direction in the plane of the mount surface.

Battery pack having a detection groove

A battery pack is loaded and unloaded to and from a battery mounting portion while sliding one surface thereof in the battery mounting portion. The one surface is provided with a pair of insertion guide grooves extending along the sliding direction and spaced from each other in the sliding direction. Each of the insertion guide grooves has an end portion fronting on a side surface of a battery main body.

A battery pack includes a circuit board disposed on the inner side of a mount surface to be mounted to a battery mounting portion, and a terminal portion at one surface adjacent to the mount surface. The battery pack is mounted into the battery mounting portion by sliding the mount surface on the battery mounting portion. A recess is formed at one or each of a pair of edge portions which are formed between the mount surface and both side surfaces adjacent to the mount surface through a pair of side edges parallel to the direction of sliding of the mount surface in the battery mounting portion, according to the kind of the battery pack.

A charger configured to charge batteries includes a housing including a plurality of battery storage chambers accommodating the batteries, the battery storage chambers being aligned in a horizontal direction such that depth directions of the battery storage chambers are parallel to each other; openings formed on first ends of the battery chambers in the depth direction, the batteries being attached to and detached from the battery storage chambers through the openings; and charger-side terminals provided on the battery storage chambers, the charger-side terminals being connect to and disconnect from battery-side terminals of the batteries stored in the battery storage chambers.
