ABSTRACT:
In a printer in which a shuttle is driven in reciprocating fashion by a rotating cam, a counterbalance assembly disposed on the opposite side of the cam from the shuttle and having a cam follower disposed along a common axis extending through the cam and a cam follower of the shuttle includes a mass in the form of a generally rectangular block mounting the cam follower at one of a pair of opposite ends thereof. Reciprocating movement of the block in response to rotation of the cam is provided by a pair of tapered flex pivots coupled to opposite ends of a base and extending upwardly and coupled to the opposite ends of the block. The end of the block opposite the cam follower receives a spring disposed against a reference surface to bias the cam follower against the cam.
