Abstract: An input scanner is provided with a housing adapted for support on a level surface, having a first external surface supporting a platen at a first angle with respect to the level surface and a second surface adjacent to the first surface and forming an angle with the first surface forming a book supporting surface; a scanning element supported with the housing for scanning motion past the platen, the scanning element supporting a linear array of photosensitive elements substantially in parallel with the platen, for image acquisition during scanning motion past the platen; and a drive arrangement, coupled to the scanning element, to drive the scanning element in scanning motion. Optionally provided is an adjustable housing support, normally in a first condition supporting the housing in a fashion maintaining the first angle relationship between the platen and the level surface, and adjustable to a second position to bring the platen into a parallel relationship with the level surface.
