ABSTRACT:
A printing apparatus employing a print ribbon provided with at least two print zones divided in width direction thereof wherein the print zones are cyclically located opposedly to a print position on a platen.
A single drive power source is used to drive a ribbon holder rocking mechanism and a ribbon winding mechanism. The drive force of the drive power source to rock the ribbon holder is transmitted to the ribbon winding mechanism through a gear train. The gear train is arranged such that the drive force is transmitted therethrough only during a predetermined range of the stroke of the rocking motion of the ribbon holder.
The rocking motion of the ribbon holder is controlled to vary the amount thereof depending upon the width of characater or symbol to be printed so as to vary the winding volume of the ribbon.
