Abstract
A photographic film processor for conveying exposed film along a serpentine film path through a series of processing racks in a respective series of processing tanks, each processing rack including a sprocket-driven endless timing belt mounted for rotation on the rack and having outer teeth for engagement with an apertured film leader card to move the film leader card along a part of the path of the timing belt, the outer teeth being laterally expandable for positive engagement with the leader card, and contractible for disengagement from it. Alternatively, the outer teeth are laterally contractible for positive engagement with the leader card, and expandible for disengagement from it. In another embodiment, the endless timing belt has spaced flexible edge tabs to pass through the apertures of a leader card to engage the card. One of the sprockets includes radial edge projections in spatial synchronism with the edge tabs of the belt to contact and flex the tabs radially outward in a position to pass through an aperture of a leader card to engage or disengage the card.
