ツド。 A plurality of printing wires, a swingable armature with one end of which the printing wires are abutted or fixed and the other end is a fulcrum, and an intermediate portion of the armature between the printing wire abutting or fixed end and the fulcrum. Printing having an opposing electromagnet, a yoke for connecting and holding the armature fulcrum and the electromagnet, and a biasing means held at one end by the yoke to constantly bias the armature and printing wire toward the recording medium. In a head wire drive device, a permanent magnet is fixed to the armature portion facing the electromagnet, a magnetic material is fixed to the end face of the permanent magnet on the electromagnet side, and the end face of the permanent magnet orthogonal to the main magnetic flux is closer to the end face of the magnetic core of the electromagnet. is also large, and the end face of the magnetic body on the magnetic core side is formed smaller than the end face on the permanent magnet side,
A printing head for a wire printer, characterized in that the main magnetic flux of a permanent magnet is aligned with the magnetic core of an electromagnet.
