第１項記載の印字ハンマ駆動用電磁石。[Claims for Utility Model Registration] 1. A rotor having two protrusions protruding in the radial direction is formed of a magnetic material and is provided so as to be rotatable by being biased in the return direction together with the printing hammer, and one of the protrusions is attached to one end of the yoke. An electromagnet for driving a printing hammer, characterized in that a core is provided for holding a coil and has a suction surface facing the protrusion of the yoke, and a suction surface facing the other protrusion is formed at the other end of the yoke. 2. The center of the radius of the arc between the end face of at least one of the protrusions facing each other and the one suction surface is eccentric from the center of rotation of the rotor, and the gap between the protrusion and the suction surface is gradually reduced by the suction operation. An electromagnet for driving a printing hammer according to claim 1 of the utility model registration claim, characterized in that:
