Abstract
A processor for processing undeveloped photographic film discs mounted on a spindle assembly has a conveyor to intermittently convey the spindle assembly from a first end to a second end of the processor along a generally horizontal conveyor path. The spindle assembly is conveyed to a plurality of processing stations along the conveyor path, with each processing station having a processing tank. During processing, the processing tanks move between an upward process position and a downward dump and transport position. A fluid dispenser at each processing station dispenses processing fluid to the processing tank at that processing station when a spindle assembly is positioned at that processing station. A spindle sensor at the first end of the processor provides a signal indicative of the presence of the spindle assembly in the processor. The operations of the conveyor, processing tank movement and fluid dispensers are controlled by a control apparatus as a function of the spindle sensor signal.
