发明名称 Film transportation device for camera
摘要 A film transporation device for a camera having an operating member adapted upon changeover thereof to a rewinding position to render a sprocket freely rotatable so that rewinding of a film is possible and a locking member for holding the operating member in the rewinding position, wherein a member is provided upon winding-up of the camera to move forward as it is operatively connected to a winding system and upon termination of the winding operation to move backward under the action of a bias force of a spring member as the operative connection is severed, whereby the backward movement of this member operates to release the operating member from the connection with the locking member, thereby enabling superimposition of a number of photographs.
