Claims

[Scope of utility model registration request]

It is equipped with a plurality of electromagnets arranged in a ring and a printing wire arranged corresponding to a plate fixed to the armature tip of each electromagnet, and the plate material at the armature tip of the electromagnet and the printing wire are separated. In addition, the end of the printing wire on the plate side is equipped with a wire button larger than the diameter of the printing wire, and each electromagnet is selectively driven to cause the printing wire to protrude from the tip of the print head, thereby printing the recording medium. A wire dot type print head that forms characters by combining dots by applying pressure is equipped with a wire button guide in which a wire button is directly guided in addition to guide means for guiding the print wire, and the wire button guide is A wire dot type print head, comprising a guide hole surrounding the outer periphery of each wire button, and configured to prevent the wire button from moving in a direction perpendicular to its axis.
