A Study for the Design of a New Mechanism of Wire Dot Print Head
Summary :
The mechanisms of the conventional spring driving types of the wire dot print heads having been studied, a new mechanism is proposed. The new mechanism is designed on the principle of the center of percussion of a body, and has the merits of good characteristics and low cost. In order to design the new mechanism reasonably, the collision vibrations are analyzed by the wave equation. It is shown in the analysis that impact printing characteristics of the new mechanism are determined by three parameters: printing medium stiffness, armature stiffness and mass ratio of the armature to the wire. The design targets are also represented by these three parameters. The relation between the center of percussion and the center of rotation of the armature is clarified on a standpoint of the collision vibration. This analysis can be applied to various mechanisms of wire dot print heads. Calculated results agree with experimental results. The new mechanism was proved to be much better than that of the conventional leaf spring by experiments.
