Claims

[Scope of utility model registration request]

Each armature has a plurality of electromagnets arranged in a ring, a plate fixed perpendicularly to the armature surface at the armature tip of each electromagnet, and a printing wire arranged corresponding to the plate. The plate material and the printing wire are separated, and 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 move the printing wire. In a wire dot type print head that forms characters by combining dots by protruding from the tip of the print head and pressurizing the recording medium, the plate material is folded double at the position corresponding to the wire button of the plate material. A wire dot type print head characterized by an enlarged area of the part that makes contact with the wire button.
