A drive system to raise and transport both print and correction ribbons on typewriters or like machines is powered by a single bidirectional stepping motor. In one direction of rotation the motor acts via a special action clutch to first drive mechanisms for raising a print ribbon and then to establish gear connections for driving mechanisms for transporting the print ribbon. In the other direction, the motor acts to establish gear connections for driving mechanisms for raising and transporting a correction ribbon.
