PURPOSE: To obtain the camera winding device by which film is surely wound to spool by controlling the turning of the film-winding spool by way of a clutch which is changed over to a non-transmission state according to fixed length detection.
CONSTITUTION: The turning force by a winding lever 11 is transmitted to a spool 15 by way of a clutch mechanism 13 and friction mechanism 14 and when the spool 15 turns, the film is wound. This causes a sprocket 16 to be turned by way of the perforations of the film. A fixed length mechanism detects the fixed length feed rate of the film and releases the coupling of the mechanism 13. Thence, the turning of the spool 15 is blocked and the automatic winding by way of a winding motor M is also accomplished in a similar manner, thus the film is surely wound to the spool which is controlled of turning according to the winding, whereby the winding of the film is accomplished.
