Claims

[Claims for Utility Model Registration] A coil bobbin having a shaft support hole formed in the center and an excitation coil wound around the outer periphery, and a coil bobbin that is inserted into the shaft support hole and abuts the end surface of the coil bobbin at the rear end. a bearing member having a stepped portion; a printing hammer movably supported within the bearing member; a spring means mounted within the bearing member and elastically returning the impact-driven printing hammer to its initial position; an impact receiver that contacts the rear end surface of the bearing member and that the non-impact side end of the printing hammer contacts when the printing hammer returns to its initial position; and an elastic member that is elastically deformable as the impact receiver moves. and a support means for movably supporting the impact receiver, the bearing member to which the printing hammer and the spring means are attached is inserted into the coil bobbin and prevented from coming off through the impact receiver by the support means. A printing hammer device featuring:
