Abstract
A document scanner for scanning an open book includes a housing and a wedge-shaped transparent platen supported by the housing. The platen defines an upper surface configured to support a book in a face-down position, and a lower surface opposite the upper surface. The platen includes a first platen portion and a second platen portion joined at a vertex to thereby define the wedge-shape of the platen. The document scanner further includes a scan head moveably supported by the housing. The scan head is configured to move generally parallel to the first platen portion and the second platen portion.
