Abstract
A ribbon lift device for selectively positioning a print ribbon and a correction ribbon to a print position for printing or correction of a character includes a first cam having a cam groove formed therein for lifting the print ribbon to the print position and a second cam having a cam profile for lifting the correction ribbon to the print position. Means are provided for coupling the first and second cams such that forward rotation of the first cam will not rotate the second cam but reverse rotation of the first cam will rotate the second cam in the same direction, and a bidirectional electric motor is coupled to the first cam whereby rotation of the motor will lift the print ribbon or the correction ribbon, depending upon the direction of rotation.
