Title:
PRINTING ACTUATOR
Document Type and Number:
Japanese Patent JP2788867
Kind Code:
B
Abstract:
PURPOSE: To improve printing speed largely by maintaining collision force and a moving stroke.
CONSTITUTION: When the holding of a plate spring 78 by a rear magnetic unit 68 is released, the plate spring 78 passes a neutral point and comes into contact with magnetic poles 92 and 94 of a front magnetic unit 86. By this contact, the plate spring 78 receives the reaction force, and kinetic energy in the returning direction is generated. The initial kinetic energy is generated in a pole contact piece 80 by the synthesized force of the reaction force and the restoring force stored in the plate spring 78. Furthermore, the force is largely accelerated energization of a coil 72. That is to say, since the initial speed is largely increased by the reaction force in comparison with the conventional device, the time of the returning path is largely shortened.
