Abstract

A photographic print sorter has a series of print slides along which the photographic prints are driven by drive rollers. Deflectors which are movable into the flow path are positioned between the print slides selectively deflect the prints into good, reject and remake print trays. Each print slide has a recess below each drive roller. The radius of each drive roller is betwen about 0.005 inches and about 0.045 inches greater than the distance from the axis of the drive shaft to the transport plane defined by the top surface of the print slide. This creates an interference fit between the drive rollers and the photographic print as the print is driven over the print slide.
