PURPOSE:To prevent the generation of an impact noise at a printing operation by the constitution wherein the pressure between the transfer material with a pressure sensitive ink layer and a recording paper is added in the direction of increasing the pressure and as a result a printing operation is performed. CONSTITUTION:A printing wire presses together an ink ribbon 19 having an ink layer, which is provided with both of the pressure sensitivity and the thermal sensitivity, and a recording paper 8 with a pressure which does not transfer the ink of a transfer material on a recording paper. The printing wire is driven in the direction of an arrow 28 by impressing a voltage to a bimorph 26 at the printing time and a printing operation is performed, wherein the ink of an ink ribbon 19 remains on a printing paper 8 due to the increased pressure between the ink ribbon 19 and the printing paper 8 and also due to the heat given by a positive characteristic thermister 18. |
