Abstract

PURPOSE:To miniaturize a camera by disposing an electrical part for operating a camera for an automatic exposure, automatic focusing, etc., between a battery chamber in the lower part of a photographic lens and a film chamber. CONSTITUTION:The electric part for operating the camera 10 is disposed between the battery chamber 30 formed in the lower part of a photographic lens optical system 20 and housing a battery 31 as a power source required for the operation of the camera and the film chamber 40 provided on the back side of a camera main body and having the passage of a film 41. Thus, it is unnecessary that a space for housing the electrical part 10 is separately provided in the upper part of the camera and the camera can be miniaturized as a whole.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera, and more particularly to a camera structure having an improved arrangement of control circuits used for exposure control, focus control and the like.

[0002]

2. Description of the Related Art As one direction for popularization of cameras, miniaturization of the cameras is desired, and various compact cameras have been developed and put into practical use. In such a background, there is also known an ultra-small camera in which a film used for shooting is a special small film, but when the film becomes small, the resolution of the image is deteriorated, and a sharp photograph cannot be obtained. Since such a special film is not widely used, it is difficult to obtain it when necessary.

Therefore, there is a demand for the development of a compact camera which uses a roll film housed in an ordinary cartridge and has a size as small as possible.

[0004]

On the other hand, from the viewpoint of facilitating the operation of the camera, exposure adjustment, shutter speed adjustment,
A camera has been developed that automatically performs operations such as focusing during shooting, and initial film feeding and rewinding, and the number of electrical parts for controlling these camera parts is increasing. Is an obstacle to the miniaturization of the.

The present invention has been made in view of the above circumstances, and by improving the arrangement of increased electric parts,
It is an object of the present invention to improve the space efficiency inside the camera and provide a more compact camera.

[0006]

In the camera of the present invention, an electric part for operating the camera, which is provided on the upper part of the camera where various operation parts are concentrated, is installed on the lower part of the taking lens having a relatively large space. By arranging the battery compartment between the battery compartment and the film compartment, the space efficiency is improved and the camera is downsized.

That is, the camera of the present invention has a battery chamber formed below the photographing lens as described in claim 1,
It is characterized in that an electric part for operating the camera is arranged between a film chamber provided on the back side of the camera body and through which the film passes.

Here, the electrical parts for operating the camera are
For example, it means electric parts such as a control circuit for AE, AF, strobe light amount control, zoom lens expansion / contraction control, and film feeding system control.

[0009]

According to the camera of the present invention, the parts such as the finder optical system, the shutter button, the remaining film number display means, and the film feeding system are provided on the upper part of the camera. The electric parts for operating the camera are arranged in a space, which has a comparatively large space between the battery room and the film room under the photographing lens, so that the electric parts for operating the camera can be accommodated. The space provided at the top can be reduced and the camera can be made smaller.

Embodiments of the camera of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective perspective view showing the external appearance of the camera of the present invention and the internal main parts thereof, and FIG. 2 is a view of the camera I- shown in FIG.
It is sectional drawing which shows the I line cross section. The camera shown in the figure has a cartridge chamber 50 for accommodating a film 41 containing a cartridge and a cartridge chamber 50 for accommodating a film 41 with a cartridge in the left and right sides of the camera body 1 with a photographing lens optical system 20 composed of a movable lens barrel 22 having a photographing lens and a fixed lens barrel 21 interposed therebetween. A battery, which is a power supply necessary for operating the camera, is provided below the photographing lens optical system 20 and is provided with a film winding chamber 60 that winds up and stores 41 by a winding shaft (not shown).
An electric component 10 for operating the camera is arranged between a battery chamber 30 accommodating 31 and a film chamber 40 through which a film 41 provided on the back side of the camera body 1 passes.

Here, a part of the partition wall forming the battery chamber 30
30A is formed integrally with the fixed lens barrel 21, and the other part 30B of the partition wall is configured so as to also serve as a partition wall of the electrical component chamber that houses the electrical component 10 for operating the camera.

Further, as the electric parts 10 for operating the camera, there are, for example, control circuits for AE, AF, strobe light quantity control, zoom lens expansion / contraction control, film feeding system control, and the like.

In this way, the electric part 10 for operating the camera is
By arranging it in the space with a relatively large space between the battery chamber 30 and the film chamber 40 under the photographing lens optical system 20, it is not necessary to separately provide a space for accommodating the electric component 10 above the camera. The camera can be downsized as a whole.

Further, a part of the partition walls of the fixed lens barrel 21 and the battery chamber 30.
30A is integrally formed, and part of the partition wall 30B of the battery chamber 30 is also used as the partition wall of the electric component chamber, whereby the number of components can be reduced and the manufacturing cost can be reduced.

As shown in FIG. 1B, the battery chamber
By forming 30 in the same shape as the round peripheral surface of the battery 31, the electric component 10 can be housed in the space 32 between the arc-shaped partition wall of the battery chamber 30 and the fixed lens barrel 21. Therefore, the space can be used more effectively.
