Abstract
Apparatus for scanning a light beam over an image surface includes a carriage assembly, including structure for directing a light beam over the image surface. A pad assembly, which is rotatably mounted to the carriage assembly, includes a pad surface. A slideway engages the pad surface to support the carriage. In use, a drive force is applied to the pad assembly so that the pad surface slides along the slideway in a given direction of movement as the light beam scans the image surface. A rotational force is applied to the pad assembly to cause the pad surface to pitch back on the slideway relative to the given direction of movement.
