Abstract
An apparatus for scanning a transparent platen including a relatively rigid plate of transparent material. In use, an original document sheet from which data are to be acquired by examination of the document through the plate is retained against the bottom side of the rigid plate of transparent material, by suction, which is applied to the interface between the original document sheet and the plate about the perimeter of the original document sheet, near the outer the edge of the relatively rigid plate. Alternatively, the original may be placed on an exchangeable, elastic support plate of transparent material retained to the relatively rigid plate by suction. Since the support plate is removable, it can be mounted on a light board, thus allowing a digitizer to determine the area to be scanned. The support plate is preferably rather thin so that it can sealingly abut originals of varying thickness.
