るワイヤドツト印字ヘッド。A printing element is attached to one end of the hammer, a vibration spring is attached to the other end, and a permanent magnet is fixed in the center of the hammer.A core pole with a coil is placed opposite the permanent magnet with a predetermined gap, and the magnetic flux of the permanent magnet In wire dot print heads, the hammer is attracted to the core pole side against the elastic force of the vibration spring, the magnetic flux of the permanent magnet is erased by energizing the coil, and the hammer is projected by the elastic force of the vibration spring to perform printing. A protrusion is formed at the lower end of the core pole, and the core pole is supported in a vibrating manner by an upper pole support plate formed protruding from the frame and a lower pole support plate that locks the protrusion of the core pole. A wire dot print head featuring a wear-resistant resistive sheet placed in contact with the upper end.
