Abstract
A book scanner for scanning a book having first and second inner surfaces and a ridge. The scanner includes a transparent platen for supporting the first inner surface, a housing, and a scanning module. The housing has a housing platen for supporting the second inner surface, and the housing and transparent platen are connected to define a first angle smaller than 180 degrees. The module is moved along a direction parallel to the ridge to scan the first inner surface. The module includes a lighting device having first and second sections. The two sections define a second angle smaller than 180 degrees; and the second section has a second end, and a first end closer to a first plane containing the transparent platen than the second end. The bent second section may provide extra light rays to compensate the brightness and thus enhance the edge image quality.
