PRINTING HEAD

PURPOSE:To eliminate the backlash of fulcrum shafts and an abrasion-resistant sheet, to prevent the generation of abrasion, to stabilize the behavior of a lever during long-term use and to eliminate the deterioration of printing quality by mounting a means fixing all of the fulcrum shafts. CONSTITUTION:An elastic sheet 14 is a part showing a feature and a fulcrum shaft 19 has a diameter slightly larger than the thickness of a positioning plate 13 and is fixed in the state held between an abrasion-resistant sheet 12 and the elastic sheet 14. Since the elastic sheet 14 presses all of fulcrum shafts in a close contact state by the elastic deformation of the sheet even when the diameter dimensions of the fulcrum shafts 19 are not uniform, the fulcrum shafts can be certainly fixed. At a stand-by time, a lever 18 is pushed by the return spring 21 held to a spring holding member 20 and pressed to a damper 22. A printing wire 10 is fixed to the leading end of the lever 18 and held by a plurality of wire guides 24 so as to be slidable in the axial direction thereof.
