放型プＩＪ＜トヘッド。[Scope of Claim for Utility Model Registration] Consisting of an armature with printed wire attached to the tip and arranged radially, a permanent magnet arranged at the other end forming the radial periphery of the armature, and an iron core wrapped with a coil. There is a print head that forms a magnetic path with an electromagnetic mechanism and attracts the armature to the iron core with the magnetic flux of the permanent magnet against the spring force applied to the armature, and energizes the coil. The armature is released from attraction with the iron core through the magnetic flux lines of the permanent magnet, and is placed in a release-type print head that prints by hitting the platen with the printing wires and ears at the tip of the armature due to the spring force. An open type IJ head, characterized in that a magnetic material is disposed on the outer periphery of the permanent magnet to form a bypass in a magnetic path formed by the armature and the iron core.
