Abstract

A battery apparatus and electronic equipment, in which the battery apparatus having a characteristic compatible with the electronic equipment can be suitably attached to the electronic equipment, and which are advantageous in miniaturizing themselves and improving their operability. In a battery apparatus (100), an identification section (18) of the battery apparatus (100) serves to identify a characteristic of the battery apparatus (100), and which is provided on an end surface (1022) and on both sides of a battery-side terminal (14) in the width direction (W) of the battery apparatus (100). The identification section (18) is configured with identification recesses (1802), (1804) formed in a manner open to the end surface (1022), and at least one of the positions, cross-sectional shapes, and lengths on the end surface (1022) of the identification recesses (1802), (1804) is formed on the basis of the characteristic of the battery apparatus. In the identification (18), the cross-sectional shape and length of the identification recess (1802) is formed on the basis of the characteristic of the battery apparatus (100).

Claims

1. A battery apparatus, comprising:

a case having a width, a thickness, and a length;

a battery cell accommodated inside the case;

a battery-side terminal provided on an end surface positioned at one of ends of the case in a length direction and electrically connected to the battery cell;

at least one locking piece on each side of the case and extending a distance in the width direction from the case, each locking piece forming a locking recess between the locking piece and an overhanging surface of the case; and

a strengthening projection located in each locking recess and extending from each respective locking piece to the overhanging surface of the case, each strengthening projection extending from the case in the width direction a shorter distance than the distance the respective locking piece extends from the case in the width direction,

wherein a bottom surface positioned on one side of the case in the thickness direction is aligned with an attachment surface of a battery attachment section of an electronic device to attach the battery apparatus by sliding the case along the length direction thereof, and the battery-side terminal comes in contact with an attachment section-side terminal of the battery attachment section.

6. The battery apparatus according to claim 1, wherein

the battery-side terminal is provided approximately in the middle of the end surface of the case in the width direction.

17. The battery apparatus according to claim 1, further comprising:

a convex portion projecting in the length direction from the end surface of the case and extending in the width direction along the end surface of the case.

18. The battery apparatus according to claim 17, wherein the convex portion extends in the width direction above the battery-side terminal.

19. The battery apparatus according to claim 1, further comprising:

a cutout portion formed in an end portion of the bottom surface of the case, the cutout portion configured to receive a locking device of the battery attachment section.

20. The battery apparatus according to claim 19, wherein

the battery-side terminal is provided at an opposite end portion in the length direction of the bottom surface.

21. The battery apparatus according to claim 1, wherein the bottom surface also includes a recess portion.

22. The battery apparatus according to claim 21, further comprising:

a convex portion in the recess portion; and

a machine name plate located in the recess portion and including a positioning groove receiving the convex portion of the recess portion.

23. The battery apparatus according to claim 1, wherein the strengthening projection has beveled edges.

24. The battery apparatus according to claim 1, wherein

a first and a second locking piece are located on each side of the case in the width direction.

25. The battery apparatus according to claim 24, wherein

a first strengthening projection connected to the first locking piece extends in the length direction a greater distance than a second strengthening projection connected to the second locking piece.

26. The battery apparatus according to claim 25, wherein

the first locking piece is closer to the battery-side terminal than the second locking piece.

27. The battery apparatus according to claim 24, wherein

a first locking piece extends in the length direction a greater distance than the second locking piece.

28. The battery apparatus according to claim 27, wherein

the first locking piece is closer to the battery-side terminal than the second locking piece.
