PURPOSE:To simplify a film feeding mechanism and to maintain the flatness of a film securely by short-circuiting a rewinding motor earlier than short-circuiting of a winding motor. CONSTITUTION:When winding and photographing operation is performed, a motor M1 rotates a take-up spool 1 to take up a film 3, and the rewinding motor M2 idles. The projection part 8b of a brake lever 8 engages a groove 7a by almost one turn of an index plate 7, and switch contacts 10 and 11 move to stop the motor M2 earlier than the motor M1. Consequently, the film 3 never sags between the spool 1 and cartridge exit. The rewinding lever 19 is moved to the left as shown by an arrow during rewinding operation. When the riser part 19a of a lever 19 rotates the side 8c of the lever 8, the switches 10 and 11 move and the motor M1 reverses while the motor M2 rotates, rewinding the film. |
