ABSTRACT:
A plurality of current patterns with regard to driving current which flows in a driving motor for a ribbon winding shaft are set in advance. The driving motor is driven based on the current pattern selected from a plurality of current patterns on an operation panel. The plurality of current patterns are set in advance so that the tension applied to the ink ribbon, which is between a printing head and a ribbon winding shaft, is an approximate predetermined value from the start to the end of ribbon winding according to the kind of the ink ribbon installed on a ribbon supply shaft.
