ABSTRACT:
A disc film and lens supporting unit (10) is assembled on a structural base plate (11). An exposure aperture (96) extends through the unit (10), and a film suporting spindle (25) is provided rotatably to support a disc film (33) such that the image frames (95) therein may be successively indexed into alignment with the exposure aperture (96). A disc film support and translational transport mechanism (18) is provided to move the spindle (25) between a load/unload position and a processing position in response to movement of a transport plate assembly (13) that is operatively connected both to the structural base plate (11) and the disc film support and translational transport mechanism (18). A film engaging mechanism (85) is presented from a film flattening assembly (75) to flatten at least that portion of the disc film (33) in register with the exposure aperture (96). A first interlocking arrangement (45, 61 and 70) is provided to disengage the film engaging mechanism ( 85) before the disc film (33) can be moved between the load/unload position and the processing position. A second interlocking arrangement (125, 150 and 151) is provided to disengage the film engaging mechanism (85) before the disc film (33) can rotated by the rotational translation mechanism (125) to index the disc film (33) and thereby bring successive image frames (95) into register with the exposure aperture (96).
