ABSTRACT:
A small, compact apparatus for processing individual rolls of an exposed composite self-developing transparency film structure. The apparatus includes two housings pivotally connected at one end to each other for movement from a film cassette loading position to a film processing position. The other end of each housing includes a recess for receiving the open end of a lighttight, linearly extendable chamber. Mounted within the housings is a pair of motor driven elongate rollers for spreading a processing liquid across the film to initiate the formation of visible images therein while simultaneously advancing the film from its cassette and into the lighttight chamber. The two housings and the open end of the chamber carry elements which, when the chamber is coupled in lighttight relation to the housings, function as a closed electrical switch located in series with the motor, thereby insuring that the film can be processed only when the lighttight chamber is properly coupled to the housings.
