Abstract

PROBLEM TO BE SOLVED: To reduce dead space due to a battery housing chamber in a battery- used apparatus, such as a camera whose exterior is made of a thin material like a metal. SOLUTION: This battery housing chamber 11 is designed such that a battery 13 can be stored in a manner inclined at a specific angle, so that the depth side of the chamber 11 is made closer to an exterior 17 than an insertion port side 21. Consequently, a wasted space can be reduced as compared to the case where the battery 13 is housed in parallel to the exterior 17, thereby improving the availability the space inside the apparatus.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device using a battery, such as a camera, having a battery storage room.

[0002]

2. Description of the Related Art In recent years, in order to reduce the size and weight of a camera, a thinly processed metal has tended to be used for the exterior of the camera instead of plastic, which is thicker in material. When metal is used, the exterior can be extremely thin compared to plastic.However, if the battery compartment is placed adjacent to the metal exterior, the edge of the metal exterior will be inserted into the insertion opening of the battery compartment. Because of the exposure, there is a problem in safety such as sharpness, and a problem in that the edge of the battery and the metal exterior are rubbed when the battery is taken in and out. In order to solve the problem, a plastic material thicker than the exterior is provided in the battery insertion opening.

FIG. 4 shows an example of such a case. A battery compartment 30 is formed along a camera exterior 31 and parallel to the exterior 31. The insertion member 33 made of a plastic material
Are provided integrally. However, in this conventional structure, a dead space 35 exists between the battery 34 and the outer case 31 by the difference in thickness between the metal outer case 31 and the insertion port member 33. At first glance, it is a small dead space, but it is not a negligible dead space in a battery-powered device such as a camera which is required to be extremely small.

[0004]

SUMMARY OF THE INVENTION The present invention has been made based on the above awareness of the problem with a battery-equipped device having a battery storage room, and uses a thin material such as metal for the exterior and provides a battery-equipped device along the exterior. It is an object of the present invention to reduce a dead space inside the device.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a battery-equipped device provided with a battery storage room along the exterior of the device, wherein the battery insertion opening of the battery storage room protrudes inward from the exterior wall surface. A meat insertion port member is provided, and the battery storage chamber is inclined from the insertion port member toward the exterior wall surface so as to be non-parallel to the exterior wall surface.

[0006] By configuring the battery storage room in this way, the dead space between the exterior and the battery can be reduced, and the space occupied by the battery storage room inside the device can be reduced. Therefore, the space inside the camera can be saved, and the space efficiency is improved.

The battery compartment can be provided along a corner of the exterior, that is, along a pair of exterior wall surfaces that are substantially orthogonal to each other. In this case, the battery storage room is provided with respect to the pair of exterior wall surfaces. It is preferable that each be non-parallel.

At present, it is practical that the exterior is made of a metal material and the insertion opening member is made of a plastic material. Is also possible.

1 to 3 show an embodiment in which the present invention is applied to a camera. The camera shown in this embodiment is a small and lightweight compact camera using a thinly processed metal for the exterior 17. As shown in FIGS. 1 and 2, a battery storage chamber 11 for storing a cylindrical battery 13 is provided at a corner on the upper right rear side (upper part of the spool chamber 25) when viewed from the front of the camera. Opening 21 which is opened and closed with
Is located at the upper end of the right side of the camera, on the back side. The exterior 17 includes an upper wall surface 17U and a rear wall surface 17B that are orthogonal to each other.
The battery chamber 11 has an upper wall surface 17U.
And the rear wall surface 17B.

Since the exterior 17 is made of a thinly processed metal, its tip is sharp, and there is a problem in terms of safety when the exterior 17 is used as an insertion opening of the battery housing 11. Therefore, the exterior 17
An insertion port member 19 made of a plastic material that is thicker than the exterior 17 and protruding inward from the exterior 17 is integrally provided at the tip of the insertion port 21.

In this embodiment, by utilizing the difference in thickness between the exterior 17 and the insertion member 19, the battery storage chamber 11 is moved from the insertion member 19 to the upper wall 17U and the rear wall 17U of the exterior 17.
It is inclined toward B (to approach both wall surfaces). The battery storage room 11 has an upper wall 1
7U, the rear wall surface 17B and the wall surface 23 provided in the camera are formed non-parallel to both the upper wall surface 17U and the rear wall surface 17B. Thus, the battery storage room 11, the upper wall surface 17U, and the rear wall surface are formed. 17B is formed non-parallel to reduce the dead space in the conventional structure.

When the battery 13 is inserted through the insertion slot 21, the battery 13 is guided by the inner wall 23 of the battery storage chamber 11, and is stored with its tip inclined in a direction approaching the exterior 17. In this structure, the tip of the battery 13 in the insertion direction is housed in a state of being in contact with or close to the inner surface of the exterior 17 at the innermost part of the battery housing chamber 11. Therefore, the battery 13 is
7, the battery 13 and the exterior 17
The space between and becomes smaller.

In the figure, the angle formed between the battery storage room 11 and the upper wall surface 17U and the angle formed between the battery storage room 11 and the rear wall surface 17B are exaggerated. For example, each is about 1.5 degrees. Of course, the invention is not limited to this angle.

The space between the battery chamber 11 and the spool chamber 25 generated by tilting the battery chamber 11 as described above includes:
For example, it can be used effectively, for example, by arranging a circuit board for a strobe light.

In the illustrated embodiment, the battery storage chamber 11 is arranged to be inclined with respect to both the upper wall surface 17U and the rear wall surface 17B of the exterior 17, but may be arranged to be inclined only to one of the wall surfaces. .

Further, in this embodiment, the case where the shape of the battery housed in the battery housing chamber is cylindrical is shown, but the present invention is not limited to the battery shape. Of course, the battery-powered device is not limited to a camera.

[0017]

As described above, according to the battery-equipped device having the battery storage chamber of the present invention, the dead space in the device can be reduced, the efficiency of the arrangement of members inside the device, and the size of the device can be reduced.
