The present invention discloses a new CIS information reading apparatus which employs rolling elements interposed between a sheet table and a CIS module for allowing the CIS module to roll over the bottom surface of the sheet table in linear direction. The CIS module is mounted on a pair of supports which uplift the CIS module in a manner that the CIS module presses tightly on the rolling elements to roll over the bottom surface of the sheet table. The pair of supports move along a pair of U grooves for guiding the CIS module along the sheet table. Since the rolling elements and the sheet table remain point or line contacts, so the friction between the CIS module and the sheet table will be very small. This helps to improve the picture duality of the images generated by the CIS module.
