ABSTRACT:
A self-developing camera utilizes a fixed cam surface and a resilient deflector strip to introduce a local longitudinal bend in a film unit as it proceeds over a relatively short portion of a film processing path from the nip of a pair of processing rollers to an exit slot. The deflector strip is secured near the end of the cam surface adjacent the exit slot with a free edge positioned to intercept the film unit proceeding from the rollers across the cam surface. The strip itself deflects upon engagement with the film unit to exert a spring force that produces in the film unit the local longitudinal bending which enhances distribution of a fluid photoprocessing composition within the film unit over its entire image-forming photosensitive area and in a layer of generally uniform thickness. The strip, however, is spaced sufficiently from the rollers and is sufficiently resilient so that it does not impede the ejection, through the same processing path, of a relatively stiff dark slide which is packaged with the film units for protection and optical shielding prior to exposure.
