ABSTRACT:
An auto-process camera film processing apparatus comprising first and second film unit processing rolls, the first roll being in fixed location, the second roll being moveable towards or away from the first roll, and one or both the rolls being driveable by a motor or similar device. The second roll is normally urged by a spring towards the first roll as far as permitted by a stop, which may be fixed or adjustable, and prevent the second roll from contacting the first roll, but permit the rolls to be brought into sufficient proximity to ensure efficient spreading of processing solution through a film unit passed between the rolls. Upon initial engagement of a film unit with the rolls the second roll is moved slightly away from the first roll by the leading edge portion of the film unit, thus avoiding jamming or damage to the film unit, after which the spring returns the second roll to a position to ensure correct processing of the film unit.
