ABSTRACT:
A motor-driven film winder for use with a camera having a film winding mechanism has a motor, a first system for transmitting rotative power from the motor to the film winding mechanism, a second system for transmitting rotative power from the motor to a mounting screw for threaded engagement in a tripod screw hole of the camera, and a switching control assembly for selectively operating the first or second system. The second system includes first and second selector gears angularly movable about the axis of a main gear and rotatable about their own axes in opposite directions. One of the first and second selector gears is selectively coupled, at a time, to the mounting screw by the switching control assembly.
