ABSTRACT:
A scanning system is provided for sequentially scanning both sides of a duplex document and projecting images onto a light sensitive linear array. In a first configuration, the platen and scan/illumination stations are fixed and the document is moved across the platen in a scan and reverse scan direction. The scan/illumination stations are sequentially energized and images of both sides of the document are directed along separate optical paths until they are redirected by a movable mirror assembly into a common lens. In a second configuration, both sides of a duplex document are sequentially scanned by movable scan/illumination stations and directed into a common lens which sequentially projects the document images onto the linear array.
