ABSTRACT:
A manually operated photographic processing system is provided for use with a film cassette containing, in stacked relationship, a dark slide and a plurality of self-processable film units that are adapted to be consecutively exposed and then processed by being advanced from the cassette after exposure, and then processed, as they are being transported through a pressure generating nip formed by a pair of juxtaposed rollers that are resiliently biased toward each other. The mechanism of the processing system is lanyard operated such that the pull force exerted by the user is utilized first to drive a film advance means that moves a film unit from the cassette into the nip between the rollers and is then transferred to drive at least one of the rollers which, in turn, provide a traction force to further transport the film unit through the rollers and process it as a function of its movement through the rollers.
