Abstract
A camera film locating feed system for processing of film strips utilizing locating holes in the film that have or tend to undergo trailing edge damage due to mishandling of the camera when the film is being advanced from one frame setting to the next. In feeding such film in the processing device a selectable control means detects film positioning by reference to the leading edge of each locating hole with the film in one orientation in the processor, and by the lagging edge with the film inverted or oppositely oriented in the processor, and rejects false detection control signals from certain kinds of locating hole damage by the delaying action of a control means gate.
Claims7
Processing apparatus comprising in combination with feed means for longitudinally advancing camera film strip and the like longitudinally therein with either end leading, processing means at a processing station for performing a processing operation on the strip at each of successive positions of advancement thereof by said feed means, said strip having locating elements successively spaced lengthwise along the strip each with opposing first and second longitudinally spaced terminal edges, corresponding first ones of such edges occupying predetermined longitudinal positions on the strip and the corresponding opposing edges longitudinal positions subject to variation, edge detector means operable in predetermined positional relation to the processing station to scan the advancing strip locating elements and provide therefrom first signals from detection of the respective leading ones of such edges and second signals from detection of the respective lagging edges thereby scanned, and control means selectively operable to actuate the processing means in response to each of the leading edge signals with the strip being advanced with one end leading, and alternatively operable to actuate such operating means in response to the lagging edge signals with the strip being advanced with its other end leading.
