Claims

[Claim for Utility Model Registration] An armature with a printing wire fixed to one end and a leaf spring fixed to the other end is attracted to a core wrapped with a coil by the magnetic flux of a permanent magnet, and strain energy is transferred to the leaf spring. Wire dot printing that prints by protruding the printing wire by canceling the magnetic flux of the permanent magnet by storing electricity in a coil corresponding to the printing data, and releasing the strain energy of the leaf spring to release the armature. In the head, at least two openings are provided in the permanent magnet surrounding the core, a connector portion of the board on which the coil is fixedly wired protrudes from the opening, and a ring-shaped yoke is laminated on the permanent magnet. A wire dot printing head featuring:
