ABSTRACT:
The impact tip of the print hammer is provided with a curved face in one direction and shaped in a cylindrically-arcuate configuration. The impact tip is formed with the surface curvature in a direction perpendicular to the direction of character height and in a convexly curved or rounded manner as viewed from the type character. This structure of the impact tip together with an optimum chamfer angle of the type character permits closer spacing of the characters.
