发明名称 Photographic print sorter with sensor to detect presence of prints in conveyor lines
摘要 A photographic print cutting and sorting apparatus cuts photographic prints from a continuous roll of processed photographic print paper and sorts the individual prints into good, remake and reject prints. The print sorter includes a main conveyor line or chute for good prints, a first branch conveyor line or chute for remake prints, and a second branch conveyor line or chute for reject prints. First and second diverters are provided for diverting the remake and reject prints into the first and second branch conveyor lines. The operation of the diverters is based upon remake and reject indicia marked on photographic prints and sensed by an indicia sensor. A print sensor located near the discharge ends of the main conveyor line and the first and second branch conveyor lines provides a signal when a trailing edge of a print passes the print sensor. A control circuit receives signals from the indicia sensor and the print sensor and controls the operation of the cutter and the first and second diverters. If the print being conveyed and sorted is a remake or reject print, the control circuit prevents the cutter from cutting another print until a signal is received from the print sensor for that print. If, on the other hand, the print being conveyed and sorted is a good print, the control circuit permits another print be cut prior to receiving a signal from the print sensor.
