摘要:
An improved print hammer (10) incorporating crossed- spring support wires (20, 22) having a round cross section so as to render the hammer relatively flexible in a direction lateral to hammer travel during printing. The spring wires are connected between a lower body portion (18) and a foot section (24). The lower body portion and foot section are designed so that the spring wires enter them substantially perpendicularly, thereby reducing stress. The foot section incorporates a pair of mounting pegs (36, 38) which serve to accurately locate the hammers in a hammer bank assembly. A pair of weights (52) can be included on the spring wires in orderto dampen recoil motion which occurs after the hammer impacts against a print character. The crossing point (21) of the spring is positioned so that the springs are flexed by a constant bending moment, thereby reducing stress on the springs.
