Abstract
Photographic apparatus for use with a fully automatic camera adapted to sequentially expose and process a film supply in the form of a disposable cassette. Upon insertion of the cassette within a cassette receiving chamber formed in the base of the camera, a loading door assembly is closed to secure the cassette within the chamber, and as a function of the closure of the noted door assembly, a latch and switch function occur substantially simultaneously to lock the loading door and energize a photographic system electronic network which includes a sequence control function and various other subsystems responsive to sequence commands. The switch and latch are structured to provide an interlock function so that the system is inoperative if the loading door assembly is not in a closed position. A manually operative latch release button is provided to disengage the loading door from its locked position.
