接させたことを特徴とするドツ・ト印字ヘッド。A printing wire, an armature that supports the printing wire at its tip, a leaf spring that supports the armature, a yoke that guides magnetic flux between the armature and the core, a permanent magnet that supplies magnetic flux between the armature and the core via the yoke, and the core. In a dot print head equipped with a coil that generates magnetic flux between the armatures in a direction that cancels out the magnetic flux of the permanent magnet, when the leaf spring is vibrated, the position near the position where the amount of displacement in the vibration direction is minimum. A dot/dot printing head characterized in that the length of the armature and the mounting position to the leaf spring are set so that the rear end of the armature is located, and the upper corner of the rear end of the armature is brought into contact with a stopper.
