ABSTRACT:
The drive includes a cable attached to opposite sides of the print head carrying carriage, looping on one side in several loops around a drive drum, and on the other side around a deflection pulley. The deflection pulley is mounted on a spring-biased pivot lever to tension the cable in an adjustable manner. The drum is connected to the drive motor in a compact fashion by means of a belt drive.
