Claim:
A book scanner for scanning a book having a first inner surface, a second inner surface, and a ridge connecting the first inner surface to the second inner surface in an open state, the book scanner comprising: a transparent platen for supporting the first inner surface of the book; a housing having a housing platen for supporting the second inner surface of the book, wherein the housing platen is connected to the transparent platen to define a first angle smaller than 180 degrees; a scanning module, which moves along a direction substantially parallel to the ridge and is for scanning the first inner surface of the book, wherein the scanning module comprises a lighting device, which comprises: a first sector substantially parallel to the transparent platen; and a second sector, substantially parallel to the housing platen, having a first end connected to the first sector and a second end, wherein the first and second sectors define a second angle smaller than 180 degrees, and the first end is closer to a first plane containing the transparent platen than the second end is so that even light rays are provided to enhance an edge image quality; and a reflective layer, which is arranged on an inner surface of the housing platen, for reflecting the light rays outputted from the second sector of the lighting device to the vicinity of the ridge of the book.
