字ヘツド。[Claims for Utility Model Registration] A leaf spring having one end fixed; an armature fixedly supported on the free end side of the leaf spring and having a printing wire attached to its tip; and a leaf spring provided at the bottom of the armature. It is equipped with an electromagnet consisting of a core and a coil, and a permanent magnet that supplies magnetic flux between the armature and the core, and by turning the electromagnet ON and OFF, the armature is released from or attracted to the core and the printing wire is driven. In the wire printing head, when the armature supported by the leaf spring is attracted to the core, the armature first comes into direct contact with the core, and the free end side tip of the leaf spring comes into contact with the armature and the core. A wire print head configured to be located within a gap formed by a wire print head.
