Abstract:
A preexposure apparatus for photosensitive films, comprising:a movable index table comprising a plurality of holding means for holding a photosensitive film shielding container; a film supply station (ST1), (ST1a) for arranging said shield container (14), (404) containing the photosensitive film (12), (402) wound and accommodated therein; a film-drawing station (ST3), (ST3a) for automatically drawing said photosensitive film (12), (402) from said shield container (14), (404) held by a holding means (20), (410); an exposure station (ST5), (ST4a) for relatively positioning said drawn photosensitive film (12), (402) and an exposure section (32), (436), and exposing a predetermined portion of said photosensitive film with an image by the aid of said exposure section; a winding station (ST6), (ST5a) for automatically rewinding said photosensitive film (12), (402) after said exposure into said shield container (14), (404); and a withdrawing station (ST8), (ST6a) for withdrawing said shield container (14), (404) containing said photosensitive film (12), (402) wound and accommodated therein again; wherein the movable index table is arranged with respect to the film supply, film-drawing, exposure, winding, and withdrawing stations so that movement of the index table transports one of the photosensitive film-shielding containers from one of the stations to another of the stations.
