ドツト印字ヘッド。・A permanent magnet in which a plurality of armatures having printed wires are fixed to a leaf spring, the armatures are attracted to the core of the electromagnet by the magnetic flux of the permanent magnet, and the electromagnet is selectively excited to act on the predetermined armature. In a dot type print head, the armature is released from the core by canceling the magnetic flux of the dot, and a predetermined printing wire is driven together with the armature by the force of a leaf spring to perform printing. By forming a contact part and an arm part by a U-shaped groove in a thin plate and placing them in contact with each other on the core, the contact part resists the spring force of the arm part as the armature is attracted. A dot print head that rotates while in contact with the core and makes surface contact with the bottom of the armature.・
