Abstract: A processor for photographic plates or like elements comprising a housing through which the plates being processed travel and further including a plurality of work stations at least comprising a developer station, a scrubbing station and a wash-off station. The scrubber station comprises a rotatably mounted brush or like scrub element disposed in engaging relation to plates passing along the path of travel defined in the housing. A flexible backup element preferably in the form of a continuous flexible belt is disposed on the opposite side of the path of travel relative to the rotating brush wherein plates being processed, when passing between the brush and the backup element will undergo a scrubbing action on the surface exposed to the brush while receiving sufficient support from the backup element to allow the scrubbing action to take place.
