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 using a film cartridge in which an outlet for film feeding is shielded by opening and closing a light shielding lid.

[0002]

2. Description of the Related Art Conventionally, it has been proposed for a film cartridge and a camera cartridge storage mechanism disclosed in JP-A-3-279947 and a film cartridge opening / closing mechanism for a camera disclosed in JP-A-6-347883. However, in order to dispose the light-shielding lid opening / closing device for shielding the exit of the film, a space for disposing the light-shielding opening / closing device is required on the rear side of the camera.

[0003]

The conventional camera described above has a problem that the thickness of the entire camera increases because the light-shielding lid opening / closing device is laid out in the space on the rear side of the film cartridge chamber. FIG.
FIG. 4 is a schematic cross-sectional view of the conventional camera described above. The camera body 2 is provided with a taking lens 7, a cartridge chamber 2a in which a film cartridge 9 is loaded, and a spool shaft 10. A spool chamber 2b is provided. A pressure plate 12 is arranged at the rear of the camera body 2.
Then, the film 8 is wound around the spool shaft 10 from the cartridge 9 via the film feeding path.

The camera body 2 is covered with an exterior body 11, but a light-shielding lid opening / closing arm 3d, which is a light-shielding lid opening / closing device, is provided at the rear of the cartridge chamber 2a so as to project therefrom. The depth of the outer casing 11 was widened by a gap Z corresponding to the protruding dimension, and the entire camera was thickened. However, if it is avoided to make the rear surface of the camera exterior body flat as described above, only the opening / closing device has an outer shape that makes a business trip, resulting in an unnatural shape.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a camera using a film cartridge having a light-shielding lid, which is thin and has a good grip.

[0006]
