ABSTRACT:
A film rewinding device in a camera in which depression of a sprocket shaft causes a clutch mechanism between a winding mechanism and a sprocket to be disengaged. This action causes a locking member to lock the sprocket shaft, to maintain the sprocket in rewinding state. The film rewinding device comprises a winding button linked to the sprocket shaft and appearing in a recess formed in an outer housing member of said camera. A bearing member is provided for the rewinding button and has a groove in the upper surface thereof. Hence, depression of said rewinding button to the depth of the groove in said bearing member will cause the sprocket shaft to be depressed to the disengagement position of the clutch mechanism provided between the winding mechanism and the sprocket. This maintains the clutch mechanism in a disengagement state by means of the locking member thereby to permit the film to be rewound.
