A film patrone which permits a film to be securely delivered from and rewound in the film patrone, and which applies low resistance to the film, thereby decreasing the rewinding load. The film patrone has a case body having shielding properties, a spool rotatably contained in the case body, a film wound in a roll around the spool, a fixed flange integrally formed on the periphery of the spool at at least one end thereof, a movable flange formed in a shape which can freely be fitted to the fixed flange so as to be movable relative to the fixed flange, and a cam unit radially provided on the fixed flange and the movable flange so as to move the movable flange along the direction to thrust the spool.
