Abstract
A book scanner with a minimized scan margin scans an open book, which has a first inner surface, a second inner surface and a binding section. The book scanner includes a book supporting structure and a scanning module. The book supporting structure is composed of a transparent first portion and a second portion, which define a first angle smaller than 180 degrees and a ridge. The scanning module scans the first inner surface of the book contacting the first portion. The scanning module can scan a scan region of the first inner surface and a distance from the scan region to the ridge is substantially shorter than 4 millimeters.
