US 4,392,730 A · Motor driven rewind device for camera

Abstract

A motor driven rewind device for a camera operating in such a manner that an actuation of a rewind control member initiates an energization of an electric motor, and driving torque of this motor brings a rewind shaft into operative connection with a spool shaft of the film patrone so that a film rewinding operation is initiated, wherein the rewind control member is made lockable in each operative position, and a compressed spring is provided between a rewind coupler engaging the aforesaid spool shaft and the aforesaid rewind shaft receptive of the driving torque of the motor to exert an absorbing action in the rotative and axial directions of said coupler, whereby the film rewind control is made more reliable.
