Photographic film cassette.

摘要

A film cassette has a cassette and a roll of film wound on a spool and contained in the cassette. When the spool is rotated, the roll of film is rotated together with it in order to feed a film leader outside the cassette body through a film passage mouth. To rotate the spool together with the roll of film together, the cassette has means for pressing an end portion of the outermost periphery of the roll of film or its peripheral surface. Where the end portion of the outermost periphery of the roll of film is to be pressed, at least one of a pair of flanges of the spool is elastically deformed to clamp both side edges of the outermost periphery of the roll of film. Where the surface of the outermost periphery of the roll of film is to be pressed, a projection and an elastic member are provided within the cassette.
