Abstract
A processor for processing undeveloped photographic film discs carried on a rotatable spindle includes a conveyor for conveying the spindle intermittently from a first end of the processor along a generally horizontal conveyor path to each of a plurality of stations along the conveyor path. The intermittent conveying of the spindle by the conveyor is cyclical, with each cycle of the conveyor having a transport portion during which the spindle is conveyed from one station to another and a processing portion during which the spindle is positioned at one of the stations for processing. The spindle and film discs mounted thereon are rotated when positioned for processing at each station, and a rotation sensor at each station senses a failure of the spindle to be rotated. The processor also has a spindle sensor which senses the presence of the spindle adjacent the first end of the processor. An indicator responsive to the spindle sensor, the conveyor and the rotation sensor identifies any station at which the spindle is located and at which the rotation sensor senses the failure of the spindle to be rotated.
