Abstract
This invention provides a flat-bed scanner capable of scanning a thick book without any distortion at the protruding binding edge. The scanning window forms an obtuse angle with the frame of the scanner supporting the scanning window. The obtuse angle allows the binding edge of the book to rest snugly over the window. The slanted structure of the frame also makes room for the image reading head to scan to the very edge of the page of the document.
