ABSTRACT:
A pivotally journalled ink ribbon cassette and an ink ribbon fork are coupled to the carriage of a printing head and arranged so as to be displaceable transversely to the line direction, in a simple manner such that both a multi-color and a single-color mode of operation are obtained. The ink ribbon fork is arranged at its free end so as to be pivotable and longitudinally displaceable on a guide rod journalled in guide arms of the ink ribbon cassette, and in that with respect to the position of the printing roller and of the printing head both means for transverse displacement of the ink ribbon fork and means for oblique positioning of the ink ribbon cassette with ink ribbon are provided.
