Abstract
A processor for processing undeveloped photographic film discs mounted on a spindle assembly has a conveyor to intermittently convey the spindle assembly along a generally horizontal conveyor path. The spindle assembly is conveyed to a plurality of processing stations on the conveyor path, with each processing station having a processing tank. During processing, the processing tanks pivot between an upward process position and a downward dump/transport position. In their upward process position, selected processing tanks are filled with processing fluids. When the spindle assembly is positioned at one of the selected processing tanks and that tank is in its upward process position and filled with processing fluid, portions of the film discs on the spindle assembly are contacted by the procesing fluid. The spindle and discs are then rotated to uniformly contact the photographic images on the film discs with the processing solution. While the conveyor advances the spindle assembly to a next processing station, the processing tanks are pivoted to their downward dump/transport position and the processing fluid is dumped from the selected processing tanks.
