Abstract
A book scanner includes a scanning table assembly having a full-speed scanning table and a half-speed scanning table moving on a pair of rails in association with each other. A first mirror mounted on the full-speed scanning table reflects light from a document to second and third mirrors to be incident on a CCD unit. The full-speed and half-speed scanning tables are supported at three points of the rails whereas some of the mirrors are supported at four points of a corresponding table. A stable image can be obtained due to substantially no distortion in the mirror surface which results from the stable posture of the tables supported at three points thereof.
