Abstract: In a disk film projector, a desired frame of an image recorded on a rotary disk of film is selectively placed at a projecting position for reproducing a selected frame in the form of a visible image. The disk film is designed to be rotatably driven to the projecting position by either manual or electrical driving devices.

Abstract: A disc film holder holds a generally disc-like photographic film unit having a plurality of image frames and indexes and disc-like photographic film unit to position selected image frames at a predetermined position, such as a print gate aperture in a photographic printer. The disc-like film unit is held coaxially about a central post and is rotationally indexed about a central axis. When the film unit is rotated for indexing a selected image frame to the print gate aperture, the film unit is biased upwardly to an indexing position so that both the top and bottom surfaces of the film is maintained out of contact with any surface during rotation. When the disc has been indexed so that the selected image is in alignment with the print gate aperture, the film unit is forced downwardly to a non-indexing position and the frame to be printed is clamped at the print gate aperture for transferring an image to photographic print paper.

The film transport assembly includes a film transport base that is slidably attached to the printer and is positionable in the print exposure cycle position. A disc film holder, positioned on the transport base, holds the disc-like film units and rotationally indexes selected film frames to the print gate for clamping by the clamping mechanism.
