いては、給電端子は省略してある。 Conventionally, this type of battery case structure has a boat-shaped concave surface 2 that encloses a cylindrical battery 1, as shown in FIGS. It is common to have a holding part for In addition, as shown in FIGS. 3a and 3b, a hole 7 is provided at the bottom of the battery case body 62.
There is also a battery case structure in which the outer edge of the battery 1 directly contacts the inner surface of the main body case 51. In FIG. 3a, the power supply terminal is omitted.

[Problem that the invention attempts to solve]

欠点がある。 The structure shown in FIGS. 2a and 2b is disadvantageous in making the device smaller and thinner because the device main body case 51 and the battery case 61 have a completely double structure. Also,
Although the structure shown in Figures 3a and 3b has a thinner device body, the battery case is structurally weak due to its frame shape, and when the battery 1 is mounted, the terminals and the spring strength of the terminals cause deformation. There are problems with strength, such as damage. It also prevents leakage of electrolyte that occurs when batteries are left mounted for long periods of time.
Since the structure shown in FIG. 3 has no bottom, the electrolyte penetrates into the electrical circuit mounting portion of the main body of the device, which not only damages individual components but also impairs the functionality of the device.

本考案は上述の様な欠点を除去し、電池の漏液
に対する配慮がなされ、しかも機器本体の小形，
薄形化に適した電池ケース構造を提供するもので
ある。 The present invention eliminates the above-mentioned drawbacks, takes into consideration battery leakage, and has a compact device body.
This provides a battery case structure suitable for thinning.

[Means for solving problems]

本考案による電池ケース構造は、電池を内包す

電池ケース本体と、肉薄突起部に嵌合する凹部を
もつ小形機器用本体ケースとを含む。 The battery case structure according to the present invention includes a battery case main body in which a thin protrusion is formed on the bottom outer surface of a boat-shaped case that houses a battery, and a main body case for a small device that has a recess that fits into the thin protrusion.

〔Example〕

次に、本考案について図面を参照して説明す

内面には、突起部８が嵌合する凹部９が設けられ
ている。 Figures 1a and 1b are an external perspective view and a sectional view of essential parts, respectively, showing an embodiment of the present invention. Terminals 3 and 4 are held on the inner surfaces of the boat-shaped battery case body 63 facing each other at both ends, respectively. The structure of this holding section is the same as that of the conventional one, and power is supplied from the battery 1 to the internal mounting circuit section through terminals 3 and 4. Ship-shaped case body 6
The bottom surface of 3 has a concave surface 2 on the inside that matches the radius of curvature of the battery 1, and a protrusion 8 on the outside that forms an arc concentrically with the concave surface 2 through a thin part. The inner surface of the main body case 52 is provided with a recess 9 into which the protrusion 8 fits.

[Effect of idea]

信頼性をも増すという効果が得られる。 As explained above, the battery case structure according to the present invention has a small distance in the height direction because a part of the outer protrusion of the case 63 containing the battery is absorbed into the recess 9 provided on the inner surface of the main case 52. Become,
The overall thickness of the device can be set to be thinner, which greatly contributes to making it smaller and thinner. Furthermore, since the battery case body 63 is boat-shaped with a bottom, it not only has sufficient strength, but also prevents the electrolyte from flowing out to the circuit mounting portion even if the battery leaks. Therefore, the effect of increasing the reliability of the device can be obtained.
