Abstract

PURPOSE: To keep the setting property of an armature constant in an impact type printer, by supporting a mass member for absorbing the kinetic enerby of the armature by a leaf spring, and providing a buffering member behind the leaf spring.
CONSTITUTION: The armature 3 with a wire fixed thereto is repulsed from a paper sheet after the printing, and strikes the mass member 17 to be stopped. The mass member 17 is fixed to one end of the leaf spring member 16 the other end of which is connected to a fitting member 12, and when the mass member 17 is given the kinetic energy of the armature 3, while it is pressing the buffering member 18 snuged in a fitting hole 13 in the fitting member 12, its energy is dissipated, and it is restored to its original position to be incontact with the armature 3. In this case, since the mass member 17 is supported by the leaf spring member 16, even when the buffering member 18 is deformed, the contact state of the mass member 17 and the armature 3 would not be changed. The adjustment of the displacement of the armature 3 is effected by an adjusting screw 15.
