Abstract
A photographic slide mounter cuts photographic film transparencies from a photographic film strip and inserts the transparencies into slide frames. The slide mounter includes a slide advance device which advances a slide frame from a slide holder along a slide track to a position where an insertion opening in the slide frame is widened. The film strip is advanced by a film advance device, which inserts the transparency into the insertion opening in the slide frame. The transparency is then severed from the strip by a knife. As the next slide is advanced from the slide holder along the slide track, it ejects the previous slide. During ejection of the previous slide, the severed transparency is inserted the final distance into the slide frame to align the photographic image on the transparency with the aperture in the slide frame. Operation of the slide advance device, film advance device, and the knife is achieved by an operating lever which is movable by an operator in a first direction through a closed path during an operating cycle. An anti-reverse mechanism prevents the operating lever from moving in a second, reverse direction in the closed path, and therefore prevents jamming and destruction of film caused by accidental reversal of motion of the operating lever.
