Abstract

PURPOSE:To eliminate image slippage by incorporating a unidirectionally rotating clutch means in either a capstan or a pinch roller and varying a position for a film when the operation is preliminarily winding up or photographing. CONSTITUTION:When unphotographed film F is wound up on a supply reel 12 from a loaded winding reel 17, a solenoid 20 is turned off, and the pinch roller 19 retreats from a capstan roller 15 due to a spring 21. The roller 15 rotates clockwise, and the entire film is wound up on the reel. When photographing starts, the solenoid 20 is turned on, and the pinch roller 19 pressure-contacts the unphotographed film F with the capstan roller 15 to drive the roller 15. When the exposed film F is wound up on the reel 17, it cannot retrograde because the rotation of the pinch roller 19 and that of the capstan roller 15 are reversed. Thus image slippage can be eliminated.
