PURPOSE:To obtain the titled printer easy to manufacture with a limited noise, by electromagnetically driving individual impact chips between a screw wire forming a screw tooth and an ink wire to reduce mechanical driving. CONSTITUTION:A wire 11 is wound on a platen 10 with a screw groove to form a screw tooth and an impact chip 1 in which the impact point moves horizontally with one rotation of the platen is set. Individual impact chips are driven electromagnetically according to the detection signal from a timing plate 15 synchronizing the rotation of the platen to perform a cross dot printing with the wire 11 and an ink wire 9. |
