Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention relates to a camera that includes a cartridge chamber into which a film cartridge containing all film is loaded, and a lid member on the side of the cartridge chamber.

(Background of the Invention) In recent years, the work of setting the leader part of the film that protrudes from the film cartridge onto the take-up spool has become cumbersome, and if the leading edge of the film is pulled carelessly, the film becomes exposed and becomes unusable. The film was completely stored inside (
A method was proposed that uses a film cartridge (with the film leader wound inside), which is inserted into a cartridge chamber equipped with a camera, and the film is pushed out from within the housing by a fork drive (U.S. Patent 484]
3] No. 9, etc.).

When loading such a film cartridge into a camera, it is preferable to open a small lid and insert it from the top or bottom of the camera, since there is no film leader section like in the past. This is because the fork and film cartridge can be easily engaged with each other, and the lid can also be made smaller. However, when loading from the bottom side, the camera must be turned upside down, and if there is no place to put the camera, it is very cumbersome to hold the camera upside down and open the lid. There is a risk of dropping the camera. Therefore, it is preferable to open the lid provided on the top of the camera and drop the film cartridge in while the camera is hanging from the strap around the neck. However, since the camera is quite small and has various buttons and other operating elements on the top surface of the camera, it is difficult to reserve a relatively large amount of lid space for the film cartridge.

Therefore, since the central axis does not move when opening and closing around the hinge axis, such as the wiring for the back cover date, if the flexible wiring is placed near the central axis, it will absorb most of the flexible board. Focusing on the fact that such a structure is not necessary, we designed the lid for the film cartridge described above to have such a structure.In other words, a hinge shaft is provided on the top of the camera, and it opens and closes around this shaft. It is conceivable that the wiring with the control section of the camera body be conducted through the vicinity of the hinge axis.

However, the lid that rotates around the hinge shaft only needs to have a very thick shaft, but such a thick shaft is not possible on the top of the camera, so when loading a cartridge, it is difficult to touch the tip of the opened lid with your fingers. This configuration cannot be used because there is a high risk of it being pushed and broken. In this regard, even if you insert the film cartridge with a sliding lid roughly and press the lid firmly, the camera body is under the lid.
This configuration is desirable because it will not break. but,
At this time, a major issue is how to wire the operating member and the control section of the camera body.

(Object of the Invention) An object of the present invention is to solve the above-mentioned problems, to facilitate loading of a film cartridge, to prevent damage to the lid member, and to effectively utilize the limited space on the top surface of the camera. The purpose is to provide cameras.

(Features of the Invention) In order to achieve the above object, the present invention includes a sliding lid member disposed on the top surface of the camera and closing the cartridge chamber;
Various operating members attached to the lid member are arranged at positions where they come into contact with the operating members attached to the lid member when the lid member is closed, and electrical connections between the operating members and the camera control circuit are arranged. a conductive member for connection, and a lid member for loading the film cartridge is provided on the top surface of the camera;
