Abstract

PURPOSE:To obtain a miniaturized, low-cost and high-speed drive apparatus, by arranging an auxiliary magnet at an end of an armature so as to face toward the back side and to promote the rotary motion of the armature. CONSTITUTION:In a dot printer wire head drive apparatus provided with a wire head 1 biased to the nonprinting direction by a return spring 4, driving magnets 22 for driving the wire head 1 toward the printing direction and others, an auxiliary magnet 31 is provided at an end of an armature 30 so as to face toward the back side. Energizing the magnet coil 22 makes the rotation side of the armature 30 an N pole and therefore repulsion force from the auxiliary magnet 31 promotes the rotary motion of the armature 30. Stopping the supply of current to the magnet coil 22 makes the attraction force of the auxiliary magnet 31 effective on the armature 30. Therefore high-speed rotary motion of the armature 30 and thus high-speed printing operation are obtained.
