Abstract
In a photographic apparatus of the type which includes a pair of motor driven cylindrical processing rollers and a film advancing mechanism for consecutively transporting and processing a stacked array of flexible, integral type self-processable film units, an improved roller mounting arrangement is provided by which the cylindrical processing rollers are mounted with their axes of rotation crossed in a predetermined manner to operate in conjunction with a post-roller film deflecting plate to assure that the film unit's processing fluid is distributed over preselected portions of the film unit in a substantially uniform thin layer, the improvement operating to correct inherent nonuniformities in the thickness of the processing fluid layer which would occur if the rollers were not cross-mounted and the deflecting plate were not present.
