Abstract
Photographic apparatus for consecutively transporting and processing a cassette of self-processable film units. The apparatus includes an integrally molded plastic housing section having a film exit slot, a pair of rotatable pressure-applying rollers mounted therewith, and a specially contoured camming surface positioned intermediate the rollers and the exit slot to intercept a film unit as it emerges from the rollers and bend it toward the exit slot as it is being advanced to the exterior of the apparatus. The location of the camming surface and its contour are specially chosen to provide the film unit with a complex curvature after it emerges from the rollers to influence the distribution of a processing fluid being spread within it as it is advanced to the exterior of the apparatus.
