Abstract
A drive mechanism for conveying a photosensitive material in a processing tank filled with processing solution such as a developer, wherein a driving force from a driving source disposed outside the processing tank is transmitted to conveyor rollers located inside the processing tank through a pair of magnetic members. One of the magnetic members is located inside the processing tank and the other is located outside the processing tank so that the magnetic members face each other with the wall surface of the processing tank between them. Accordingly, the outside magnetic member is rotated by the driving force from the driving source. The rotation is transmitted to the inside magnetic member by means of a magnetic force, which rotates the conveyor rollers. The driving force is transmitted without a driving shaft or the like through the wall of the processing tank. Further, the processing tank can be made sufficiently airtight, thereby reducing degradation of the processing solution by oxidation.
