Abstract (en)

A ribbon winding side ribbon and a ribbon supply side ribbon holder (13) are provided for supplying an inked ribbon (12) to a thermal printer. A ribbon tension detection plate (17,28) is rotatably supported on a frame so as to be rotated in dependency on tension of the inked ribbon. A ribbon tension adjusting means is provided to be responsive to angular position of the ribbon tension detecting plate for applying a load on the ribbon holder so that the tension of the inked ribbon is adjusted. <IMAGE>
