Abstract
A document scanning apparatus is disclosed which provides a scan and rescan motion to a scan carriage using only mechanical drive components. Motion of a rotating photoreceptor is transferred, via drive pulley components to a main drive shaft having, in a first embodiment, a pair of pulleys fixedly mounted at the ends. The pulleys drive cables which, in turn, drive the scan carriages of the disclosed system in a scan or rescan direction, dependent upon the drive pulley rotation. The drive pulley rotation is controlled by a movable hub assembly on a drive shaft and by a linkage mechanism which is periodically engaged by the scan carriage at a beginning or end of scan position. Mechanical engagement of the scan carriage with the linkage mechanism causes a reversal of the drive pulley rotation and hence a reversal of the scan carriage direction of travel. In a second embodiment, a rack and gear arrangement is used to drive the scan carriage.
