ABSTRACT:
A neghold assembly permits withdrawal of a disc-like film unit from a clamping aperture assembly stationarily positioned on the photographic printer that holds a selected film frame at the print gate aperture. The disc-like film unit is held on a movable film transport assembly which engages a switching mechanism that actuates the clamping aperture assembly to an open position, releasing the disc-like film unit before the transport assembly can be moved from a print exposure cycle position. 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.
