Abstract
Leaf spring 1 keeps print hammer 2 in its waiting position. Leaf spring 1 is shaped and supported at its two ends such that as print hammer 1 is accelerated in the direction marked by arrow 3, the spring tension decreases, permitting print hammer 1 to fly freely. Thus, there is a negative spring characteristic. Having impacted the platen, the rebounding print hammer is decelerated by the spring tension to be finally kept in its waiting position by the special shape of leaf spring 1.
