ABSTRACT:
A photographic print stacking device is positioned proximate the discharge end of the conveyor system which conveys photographic prints from a photographic print cutter. The print stacking device includes upper and lower print receiving elements, which are yieldably urged toward one another. The lower print receiving element is movable generally downward and away from the upper print receiving element as the prints are deposited on the lower print receiving element. The conveyor system delivers the prints to the stacking device with sufficient force to carry the prints between the upper and lower print receiving elements until their front edges engage a stop element. As a result, the rear edges of the prints are all substantially in alignment at a location proximate the discharge end of the conveyor system. The stop element preferably is releasably latched in an operative upstanding position and may be moved out of the way by the operator when removing an accumulated stack of prints.
