PURPOSE:To make quick rewinding motion possible by driving a rewinding shaft and a spool in such a way that the film releasing speed of a winding spool is higher than the film winding speed of a film patrone shaft during rewinding. CONSTITUTION:A driving motor 8, transmission mechanisms 12-16, 18, 26, 20, 24, 30a, 31, 10, 34 which can transmit the driving force of said motor 8 to a film winding spool 2 and a rewinding shaft 6 connected to a film patrone shaft and operate the spool 2 and the shaft 6 in such a way that the film releasing speed of the spool 2 is higher than the film winding speed of the film patrone shaft connected to the shaft 6, and disconnecting means 12a, 16, 18, 26, 20, 24, 30a, 31, 32, 35, 4a which free the sprocket 4 are provided. |
