ワイヤ印字ヘツド。[Scope of claim for utility model registration] An armature with a printing wire fixed to the tip,
A core provided opposite to the armature, a leaf spring to which the armature is joined and supported in a cantilevered manner, and a magnetic flux is generated to resist the elastic force of the leaf spring to move the armature to the core. In a wire printing head consisting of a permanent magnet that attracts the magnet, and a coil that is wound around the core and generates magnetic flux from the core when energized, canceling the magnetic flux of the permanent magnet and releasing the armature, (a) the board The spring is disposed to face the end surface of the core, and (b) a protrusion is formed at the free end of the leaf spring to protrude from the joint with the armature and elastically abut against the end surface of the core. wire print head.
