ABSTRACT:
A power-driven rewind device for rewinding a film taken up on a take-up spool shaft onto a supply spool shaft comprises a first gear coupled to and rotatable with the supply spool shaft, a second gear operatively associated with the rotation of a motor when the film is rewound, a third gear meshing with both of the first and second gears and thereby displaceable between a coupled position and a disengaged position, and change-over means operatively associated with the rotation of the second gear to displace the third gear to the coupled position.
