Abstract
Hammer actuators are mounted on a support. Instead of moving the entire massive support to traverse the paper for each line, only a low inertia member, which positions the impact ends of the print wires, is moved. The internal structure of the member facilitates minor curvature of the print wires as the member moves. The member is rapidly reciprocated relative to the support, but 'dwells' for a short time at each extreme to permit indexing of the paper. Ehnanced graphic capability is possible because each print wire can print a plurality of dots for each line.
