Abstract
A cable drive system is provided in which a fixedly mounted reversible motor imparts translational motion to a plurality of pairs of elements such as the right and left pairs of paper moving tractors in a high-speed printer. By means of a continuous cable loop routed around passive rotational elements, each element of a pair of elements, each of which is rigidly attached to the cable, can be translated the same distance in the same direction as the other while the relative alignment of one element with respect to the other element is maintained. Means for selectively translating one pair of elements independently or a plurality of pairs of elements simultaneously while maintaining the distance between the pairs are provided.
