Abstract
PURPOSE: To perform film winding surely and make possible rewinding of film without making any special operation by so defining the free end of the driven gear side of a kick spring as to be turnable only in one direction.
CONSTITUTION: A gear 13 driven in association to film winding operation and a driven gear 15 cooperating to a take-up spool 3 are connected by a kick spring 16 and the power transmission to the gear 15 is accomplished as the spring 16 is wound and tightened when the gear 13 turns. In addition, a forward and backward rotatable sprocket gear 30 intermeshing with the perforations of the film is provided and when the gear 30 has turned the specified quantity, the free end of the gear 13 side of the spring 16 is detained, by which the power to the gear 15 is cut off. Hence, the film of the specified amount may be surely fed by one winding operation.
