Claims

[Claim for Utility Model Registration] Consisting of a permanent magnet, an electromagnet, and a leaf spring that supports an armature with wires attached, the electromagnet is selectively excited to generate magnetic flux in the opposite direction to the permanent magnet, thereby making the leaf spring permanent. In the wire vibration damping mechanism of a dot printing head, which prints by releasing the wire from the magnetic force of the magnet and printing, it consists of a flat peripheral material with a hole in the center, a head inserted into the hole in the center, and a wire surrounding it. A wire vibration damping mechanism in a dot printing head, characterized in that a vibration damping material consisting of a columnar core material forming a gap through which the wire passes is placed in the middle of the wire.
