ABSTRACT:
An instant photography camera can contain a combination of improved features including cleaning pads for continuous cleaning of spread rollers throughout the life of the camera, a flexible non-coiled film shade for preventing light piping along a film unit which is exiting the camera, and a dual independent spread control feature on a film cassette so that the same film cassette can be used in different cameras. The film cassette includes first and second spread control features for providing even spreading of processing liquid across a film unit; the first spread control feature used in a straight film track configuration, and the second spread control feature being used in a chute film track configuration.
