Abstract

PURPOSE: To provide a printing lever for an impact type printer which is fast in response speed, stable in response operation and long in life, and of which hammer member to be fixed to a leaf spring member, which supports the print lever by cantilever system, so as to oppose a platen is made of ceramic.
CONSTITUTION: It is possible to obtain a good result that the wear ratio of a hammer member 6 made of ceramic (specific gravity; 3.8, Vickers hardness; 1800HV) is less than 1 after printing 30 million characters. The displacement (a) of the hammer member 6 and the displacement (b) of the leg 5c of a spring smoothly response without causing disturbance and deviation of phase at all. Especially the rise characteristic of the hammer member 6 is excellent and it operates sharply and the time t3 which it takes to impact against a platen 18 and time t4 which it takes to return to its rest position are shortened together.
