Claims

[Claims for Utility Model Registration] (1) In a film cartridge with a built-in spool for winding the film, the cartridge body is made of synthetic resin, and the cartridge body consists of a pair of halves connected via a hinge along a generatrix. The two semi-cylindrical portions are formed of a cylindrical portion, and step portions that closely fit each other are formed on the end faces of the generatrix direction edges connected by the hinge portions of the two semi-cylindrical portions, and the diameters of the side walls of the two semi-cylindrical portions are Fitting portions that closely fit each other are formed on the direction end faces, and serrated engagement claws that engage with each other are formed at both ends of the generatrix direction edges constituting the film drawer openings of the two semi-cylindrical portions. Film patrones are characterized by the fact that they are formed individually. (2) The film cartridge according to claim (1), wherein one of the fitting portions is a convex strip and the other is a concave groove. (3) The film cartridge according to claim (1), wherein one of the fitting portions is a stepped convex strip, and the other is a stepped groove. (4) The film cartridge according to claim (1) for utility model registration, wherein the mating portions of the two fitting portions are stepped portions. (5) The film cartridge according to claim (1) of the utility model registration, wherein the mating portions of the two fitting portions are a combination of juxtaposed convex stripes and concave grooves.
