ABSTRACT:
An apparatus in combination with a photographic printer indicates the position of a selected film frame at a print gate aperture relative to other film frames in a disc-like film unit having a plurality of film frames. The apparatus includes a disc-like film unit holder for rotationally indexing selected film frames to the print gate aperture having a first gear. A second gear provides motive force through a suitable actuating mechanism for rotationally indexing the disc-like film unit on the holder assembly. A third gear having indicia for indicating relative positions of the film frames in the disc film unit is rotatably positioned between the first and the second gear and cooperates with the first and the second gear to rotationally index the disc-like film unit on the holder assembly. Only the indicia that indicates the selected film frame positioned at the print gate aperture is viewable.
