ABSTRACT:
A housing adapted to be secured to a camera contains a battery-driven motor coupled to a gear. The gear supports a leaf spring which, when the gear is rotated, lifts a pin from within the housing into an auxiliary shutter-releasing socket within the camera, thereby operating the shutter. The gear also supports a lever which is moved during gear rotation into operating relationship with a winder mechanism extending from within the housing into the camera's film winding socket. Actuation of the winder mechanism causes the film to be advanced. Electrical circuitry is provided within the housing for controlling the operation of the motor through the selective energization of a relay.
