Abstract

PURPOSE:To improve the radiation of heat and to reduce the vibration by a method wherein a armature and a magnet are separately constituted to facilitate machining accuracy control and parts change, further, the magnet bank being molded by epoxy resin having a good thermal conductivity. CONSTITUTION:For the printing head of a matrix printer which is printed by a plurality of print wires, one solid frame is formed by a flange type slender part 1a and a flange part 1b, at the periphery of the flange 1b thereof, the base 3a of the armature 3 is radially fixed respectively, separately a magnet bank 9 being formed with a plurality of magnet assembly 4 having a permanent magnet 4a and a magnet coil 4C to separate the frame side 1 and the magnet bank side 9. Further, the magnet bank 9 is molded with the epoxy resin having a good thermal conductivity including positioning a plurality of magnet assembly 4.
