Abstract
Document scanner having a drive cable system constructed to provide desired alignment between the cables. The drive cables are wound around cylindrical drive members in a spiral fashion from two securing locations. One end segment of the cable spirals toward the center of the drive member in one direction and the other end segment of the cable spirals toward the center in the opposite direction. During the rotation of the drive member, the cable end segments add and subtract turns without changing the overall axial length or position of the cable winding or the alignment of the cable portions leaving the drive member.
