ABSTRACT:
A duplicating camera, especially, a diffusion transfer type duplicating camera including an exposure box in which a scanner for scanning across the surface of an original in the form of a slit is incorporated and a transfer box in which a sheet of photosensitive material is exposed to light so that a set of slit images from the exposure box can be formed on the photosensitive material, and in which the image recorded on the photosensitive material is transferred to an image receiving material. These exposure and transfer boxes are arranged in an adjustable manner so that the scan axis of the scanning unit can be aligned with the transfer axis of the photosensitive material. In the exposure stage, an exposure table on which the photosensitive material is transferred is positioned above conveyor rollers disposed on both sides of the exposure table, so that a nominal rise occurs in the photosensitive material traveling above the exposure table.
