Claims

[Scope of utility model registration request]

A self-processing film unit equipped with a bag for storing processing liquid is clamped to split the bag and spread the processing liquid onto the photosensitive surface of the film unit.A pair of rollers locks one corner of the film unit. In the instant camera, at least one of the pair of developing rollers is arranged such that the gap between the developing rollers is at the center in the longitudinal direction of the rollers. The roller is formed into a shape that is large and becomes smaller near the end of the roller that comes into contact with the periphery of the side edge of the image forming surface of the film unit, and the diameter of the end of the roller is made smaller on the feeding side by the film feeding mechanism. The roller structure of an instant camera is characterized by its asymmetrical formation.
