Abstract

PURPOSE: To obtain a simply structured type wheel with low cost by forming a vibration damping ring formed of webs curved within a plane of printing motion by injection molding positioned on about half a diameter of a length of spokes. CONSTITUTION: The type wheel 1 has a center hole 2 which is fixed on a rotation positioning axis and has a hole 3 for a driving finger near the boss. The spoke 4 has a face 5 for a character at the free end and may have a wedge for centering if necessary. The webs 6 are formed as a ring on the middle of the spoke 4 connecting all spokes 4. The curved web part 6 between spokes 4 works as a hard spring actually to damp the vibrations in both directions of typing and adjacent spokes effectively. The waved part 6 is bent instead of the adjacent spokes by the spokes 4 when it is driven for typing.
