ABSTRACT:
Mechanism to raise and transport print and correction ribbons in typewriters and similar machines as a function of the direction of a rotation of a motor. The required motions are brought about by means of a cam wheel containing different cams and by appropriate cam followers, and provision is made to maintain ribbon raised to the typed line level so that during rapid printing only transport steps need to be carried out. It is also possible with the mechanism to effect transport steps of different size, to meet the requirements of the ribbon type used.
