イヤドツト印字ヘツド。[Claims for Utility Model Registration] A magnetic circuit is formed by an armature with a wire fixed to the tip, a core around which a coil is wound, a permanent magnet, and a core yoke, and the armature is connected to the core by a spring. The core is attracted by the magnetic flux of the permanent magnet while being biased in the direction of separation, the magnetic flux of the permanent magnet is erased by energizing the coil, and the elastic force of the spring causes the core to be attracted to the core. A wire dot printing head that prints with a wire of the armature by separating the armature from the core, and an auxiliary magnet that generates magnetic flux in the opposite direction to the magnetic flux of the permanent magnet inside the armature.
A wire dot printing head characterized in that it is provided outside the magnetic circuit.
