JPH09105994A - Camera and cover closing device for camera - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a cover from being inadvertently opened so as to protect the inside such as light shielding for film at ordinary time and to easily open the cover if necessary so as to improve workability by providing a 2nd cover with which an operation means is covered. SOLUTION: A back cover 107 largely opens/closes the back surface of the body of a camera, so that a film traveling path inside a camera is exposed. By operating a back cover closing member 108 locking the back cover 107 in a closed state and releasing the locking in a perpendicular direction to a paper surface, its engagement and disengagement with/from a pawl part 107a formed on the back cover 107 is executed. The operation part 108a of the member 108 is exposed on the side wall of a cartridge chamber 102b. In the case of opening the back cover 107, the operation part 108a of the member 108 exposed to the chamber 102b is operated after opening the cover of the chamber 102b which is opened/closed to load or take out a cartridge, whereby the engagement with the back cover 107 is released and the back cover 107 is opened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a camera cover opening / closing device.

[0002]

2. Description of the Related Art Conventionally, films used for cameras are
The front end of the film was pulled out from the film cartridge in advance, and the film was loaded into the camera for shooting.

On the other hand, in recent years, a cartridge in which the leading end of the film has not come out of the cartridge is loaded in the camera, and the spool in the cartridge is rotationally driven to feed the film out of the cartridge so that the leading end of the film and the body of the camera are pressed. It has been proposed to guide the film to a slit formed between the film and the aperture of the camera, and then wind the film around a film take-up spool of a camera to complete automatic loading of the film.

[0004]

In this type of camera, the film cartridge can be loaded and unloaded along the longitudinal direction (spool axis direction) of the film cartridge as it is. Since the opening for taking out is also small, it is not necessary to open and close the back cover as in the conventional case. From this, the user of the camera inadvertently operates the locking member,
It is possible to eliminate the conventional back cover, which has a risk of exposing the photographed film.

However, in the case of such a structure, the following problems newly occur.

Compared with a conventional camera whose back cover can be easily opened and closed, for example, when the film is entangled inside the camera and cannot be fed, the back cover is easily opened to take out the entangled film. I will not be able to.

The present invention has been made in view of the above circumstances. An object of the present invention is to prevent the camera cover from being opened unintentionally for internal protection such as light shielding of a film, and when necessary. An object of the present invention is to provide a camera or a cover opening / closing device for a camera, which can easily open the cover to improve workability.

[0008]

In order to achieve the above object, the present invention comprises a first cover of a camera, an operating means for permitting an opening operation of the cover, and a second cover for covering the operating means. And a camera having.

Further, in order to achieve the above object, the present invention provides a cover opening / closing device for a camera, which has an operating means for allowing the opening operation of the first cover of the camera and a second cover for covering the operating means. To do.
