ABSTRACT:
An optical film printer has a projector station and a camera station each of which interchangeably receive a complete 16 mm, regular 8 mm, or super-8 mm film transport unit, including drive sprocket wheels and incremental film advance mechanism. A lens is disposed between the stations. A pair of output members of a power transmission system rotate responsive to a drive motor. Each film transport unit incrementally advances film past an aperture responsive to rotation of an input member that engages one of the output members and when received by the corresponding station. Each film transport unit advances the same number of frames per unit angular displacement of the output members. The unit at the projector station is movable toward and away from the camera station, and the lens is adjustable in three directions. The power transmission system permits each output member to be independently driven in both directions or to be driven in synchronism. The power transmission system, film drive motor, reel drive motors, and control electronics are all housed in an enclosed chassis having a top panel on which the reels and the film transport units are all mounted.
