ABSTRACT:
A film processing apparatus is provided for use with cassette holding a processing sheet roll yieldably carrying, on one surface thereof, a substantially uniformly distributed supply of film processing liquid which is adapted to be applied to a surface of an exposed photographic film unit to initiate film processing. The cassette has a vapor and gas impervious housing including a film entry opening and an exit opening through which the exposed film unit and the processing sheet are advanced in superposed relation to apply the liquid to the film surface during a film processing mode of operation. To protect the processing sheet from prolonged contact with the ambient atmosphere during a non-processing mode, the apparatus is provided with system for sealing the cassette entry and exit openings.
