Abstract

This invention provides a flat-edge scanner capable of scanning a thick book without any distortion at the protruding binding edge. The binding edge of the book is placed at the corner of a scanning glass window and the frame supporting the glass window so that the book can lie snugly over the window. The scanning window area is extended to the edge of the frame supporting the scanning window. All the optical system and the driving mechanism lie inside the boundary of the scanning window to increase the scanning range.
