Abstract
The invention concerns a mechanism for raising and feeding different types of ink ribbons in typewriters and similar machines. With a simple design and using only one motor under programmed control, the mechanism is capable of utilizing ink ribbons economically, e.g. printing alternately in several printing zones of a ribbon or in several colors. It also feeds ribbon by a length which corresponds to the type of ribbon, or type of operation, e.g. proportional typing. The starting point for the various functions is a basic position to which the mechanism is positioned by the motor.
