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.
