Claims

[Scope of utility model registration request]

An outer rail and an inner rail are formed in the vicinity of parallel edges of the exposure aperture formed in the camera body, and when the film pressure plate is brought into contact with the outer rail, the film pressure plate In a pressure support structure for a film pressure plate in which a gap for film passage is formed between the film pressure plate and the inner rail, a support shaft is installed toward the rear at a portion of the film pressure plate that is inside a portion corresponding to the outer rail. a support part that is fitted into the camera body and is slidable a predetermined amount in the optical axis direction; a pressing part that presses a portion of the film pressure plate that corresponds to the outer rail; The fitting part that is fitted and supported by the support shaft implanted in the back cover has a plate spring member that is integrally or integrally formed with the fitting part, and the pressing force accompanying the closing of the back cover is applied to the plate spring member. The film is characterized in that the spring force is converted into a spring force and transmitted to the pressing part through the fitting part, and the spring force acts intensively on a portion of the film pressure plate corresponding to the outer rail. Pressure plate support structure.
