Battery cartridge having a recess for detecting misuse and/or recessed terminals
First Claim
1. A battery pack comprising:
- a casing for housing batteries, said casing having an upper portion and a bottom portion;
a plurality of electrodes formed in said bottom portion of said casing for electrical connection with said batteries, said electrodes functioning as charging electrodes when said battery pack is connected to a battery charger and said electrodes functioning as power supply electrodes when said battery pack is connected to an electrical apparatus; and
a detection recess formed along a center line on a bottom surface of said bottom portion of said casing for detecting when said pack is positioned correctly in an appropriate battery charger or electrical apparatus, wherein columnar batteries are accommodated in said casing in two rows extending along opposite sides of said center line of said bottom surface and wherein said detection recess is formed along said center line in between said two rows.

Abstract
A battery pack having a detection recess formed along a center line of a bottom surface arranged such that the detection recess is engaged with a convexed portion of a battery charger. Therefore, whether or not the battery pack is properly attached to the battery charger can easily be detected by the inclination of the battery pack about the center line. Further, a battery pack is arranged such that an aperture is formed on an outer surface of the battery pack and an output terminal is inwardly disposed on the aperture. Therefore, damage to the batteries in the battery pack caused by a short-circuit resulting from products made of conductive metal material such as a key ring, necklace, or chain contacting both of the output terminals, as occurs when terminals are disposed on the outer surface of the battery pack, can be prevented. Furthermore, the battery pack includes apertures with output terminals disposed therein for discharging dust or the like away from the terminals into the interior of the casing or out of the casing through a hole. Therefore, the accumulation of dust or the like within the apertures and upon the output terminals is prevented.

19. A battery pack having a battery accommodated therein comprising:
-
a casing for housing said battery, said casing having an upper portion and a bottom portion, a bottom surface of said bottom portion having a concave portion at one end thereof; a plurality of electrodes formed in said bottom portion of said casing for electrical connection with said battery, said electrodes functioning as charging electrodes when said battery pack is connected to a battery charger and said electrodes functioning as power supply electrodes when said battery pack is connected to an electrical apparatus; a marker slidably disposed on said concave portion of said bottom surface, said marker forming a sliding plate and said marker having an enlarged protruding section at one end thereof; a hole formed in said concave portion for receiving the sliding plate of said marker opposite the protruding section; and an aperture formed adjacent to said concave portion in said bottom portion for viewing the position of said sliding plate;
whereby said sliding marker slides into said hole when said pack is connected to an electrical apparatus and said aperture visually showing such position thereby indicating that the battery has been used, and said sliding marker is moved in the opposite direction to an opposite position by said protruding section when said pack is removed from a battery charger and said aperture visually showing such position thereby indicating that the battery has been charged. - View Dependent Claims (20, 21, 22)

23. A battery pack having a battery means accommodated therein comprising:
-
a casing for housing said battery means inside, said casing having an upper portion and a bottom portion; a plurality of electrodes formed in a plurality of corresponding apertures, said apertures being disposed within said casing at a side of said bottom portion of said casing for electrical connection with said battery means, said electrodes functioning as charging electrodes when said battery pack is connected to a battery charger and said electrodes functioning as power supply electrodes when said battery pack is connected to an electrical apparatus, wherein each of said plurality of apertures extends from said side of said bottom portion of said casing to the inside of said casing, whereby any dust accumulating on said electrodes may be discharged through each of said apertures into said casing. - View Dependent Claims (24, 25, 26)
