When the coil is not energized, the armature is attracted to the yoke by the magnetic field of the permanent magnet, and when the coil is energized, the magnetic field of the permanent magnet is canceled and the spring is released, and the restoring force of the spring causes the tip of the wire to A spring-charged wire dot matrix printer head that prints by colliding with a platen is characterized by the provision of an elastic member that comes into contact with the rear end of the wire when the excitation of the coil is stopped and the wire returns to its original position. printer head. (2) The printer head according to claim 1, wherein a wire guide for guiding the rear end of the wire is provided in front of the elastic member so as to be in contact with the elastic member.
