Abstract

PURPOSE:To keep the variation in the pressing force between the first period of continuous printing and the following dot printing period almost constant in a wide temperature range by stopping a print wire and an armature at the restoration positions by a kind of dynamic damper. CONSTITUTION:After the dot printing, a print wire 6 is retreated and an armature 3 is also turned in the direction of arrow 29 by the repulsion of a recording paper and an ink ribbon and the force of a returning spring 10, and when reaching the restoration positions, they collide against a laminated member 20 and stop at the restoration positions while making damping oscillation. The member 20 given the kinetic energy of the wire 6 and the armature 3 is gradually stopped while being vibrated becauce the kinetic energy is gradually lost by mainly the viscosity of an elastomer 26. The amplitude of oscillation during the restoration of the wire 6 is determined by mainly the repulsion of the member 20 when being collided by the armature 3, and the magnitude of the repulsion is almost governed by the mass ratio in a movement system including the member 20 and the armature 3, but little by temperature.
