ヘツド。[Claim for Utility Model Registration] Printing fixed to the tip of the armature by attracting the armature with the magnetic flux of a permanent magnet to bend the leaf spring, and then canceling the magnetic flux of the permanent magnet with an electromagnet to release the armature. In the dot printing head that drives the wire, the rear end of the armature extends closer to the support part of the leaf spring than the fixed point of the primary vibration caused by the leaf spring, and has a contact point at the rear end of the armature, and when the armature is attracted , a magnetic damper plate having a magnetic damper piece that moves by the uplifting force of the rear end of the armature that rises with the fixed point as a rotational fulcrum is installed in a state where the magnetic flux of a permanent magnet can pass through the magnetic damper piece, and the magnetic flux A dot printing head characterized by applying a restoring force to the magnetic damper piece, thereby applying a biasing force to the rear end of the armature to reduce the uplift speed.
