A plurality of cores to which excitation coils are attached are arranged radially around the outer periphery of an annular yoke, and a plurality of armatures are provided, each with its base end facing the suction surface of the core. In a dot printer head, which is rotatably supported facing each other, the armature is rotated by the suction force of the core, and the free end of the armature drives the print wire. A dot printer head characterized in that the armature is supported by the torsion spring in a direction away from the suction surface of the core. 2. The dot printer head according to claim 1, wherein cooling fins are in direct contact with the outer periphery of the excitation coil.
