Abstract
A reciprocating printer shuttle which includes a printhead constrained to move with a linear motion and driven by a drive link attached to a belt which runs continuously in one direction around two spaced pulleys. The printhead motion is parallel to the run of the belt between the two pulleys. Printhead motion reverses each time the point of attachemnt of the drive link passes around one of the pulleys. A counterbalance which has the same mass as the printhead, and is constrained to move parallel to it, is also driven by a drive link attached to the belt. The counterbalance drive link is attached halfway around the belt from the printhead; the counterbalance's decelerations and accelerations at each end of the reciprocating motion are, therefore, exactly opposite to those of the printhead.
