タの印字ヘツド。[Scope of Claim for Utility Model Registration] (1) In the printing head of a wire dot printer, which prints by attracting a movable piece of iron using an electromagnet and striking a wire against the round platen through the movable piece of iron, the wire dot printer prints according to the curvature of the round platen. 1. A print head for a wire dot printer, characterized in that means is provided for varying the value of each air gap corresponding to each wire disposed facing the round platen. (2) The printing head for a wire dot printer as set forth in claim (1) of the utility model registration, characterized in that the value of the air gap is varied by changing the thickness of the movable iron piece. (3) The wire described in claim (1) of the utility model registration claim, characterized in that the value of the air gap is varied by changing the height dimension of the surface of the electromagnet to which the movable iron piece is attracted. Print head of dot printer. (4) The utility model registered in claim (1) is characterized in that the value of the air gap is made different by changing the plate thickness of the portion corresponding to the position of each movable iron piece of the damper. Print head of wire dot printer.
