Abstract
An optical reader and the driving motor of a scanner are integrally mounted on a movable module, which can slide back and forth along a track to scan an image. The driving motor exerts a force on a fixed rack attached to the frame of the scanner through a pinion. The reaction to the force causes the movable module to slide. The rack and pinion mechanism can be replaced with a friction tape and roller combination, or a steel wire wrapped around a wheel attached to the movable module.
