Abstract: PURPOSE:To make it possible to obtain printing by the weak impact output of a hammer without lowering printing grade, by moving the heated part of a ribbon heated by a heater to a position where typing is performed by the hammer at the time of printing. CONSTITUTION:The one-character part 9A of a taken-out ink ribbon is heated by a heater 10. The taking-out and taking-up of the ink ribbon 9 are controlled so that the heated one character part is always guided to a printing position. When the one-character part 9A of the ribbon 9 was heated, said ink ribbon 9 is taken out by the input of a printing key until the one character part 9A arrives the printing position where printing is carried out. The ink ribbon 9 is taken out simultaneously with the completion of printing to be brought to an one-character taken-up state. By repeating this feed operation of the ink ribbon 9 at every printing operation, high grade printing can be succeedingly kept by small impact force of a hammer while the heated part of the ribbon 9 is efficiently suppressed to a min. degree.
