Zusammenfassung:PURPOSE: To provide a film cassette capable of preventing an exposed film from being loaded. CONSTITUTION: The film cassette 1 is provided with a shell for storing the film and an indicator/lockout means 101. In the case of inserting the film cassette 1 with the indicator/lockout means 101 which lies at non-exposure position into the loading chamber of the camera, a cam surface 127 occupying half the cassette is not covered with a lockout rib 121. Thus, the film cassette 1 is inserted into the loading chamber. On the contrary, in the case of inserting the film cassette 1 with the indicator/lockout means 101 which lies at a partial exposure position, or at a complete exposure position, the cam surface 127 is covered with the lockout rib 121. Thus, the film cassette 1 is prevented from being inserted into the loading chamber.
