ABSTRACT:
Function controlled raising and transporting mechanism for the selective control of a print ribbon or correction tape by means of a power drive and freewheeling clutches operative to effect print ribbon or correction tape transport incident to carriage motion in print direction only. In certain commanded functions such as spacing, tabulating, etc., both the print ribbon and correction tape transports are disabled by moving output elements of the freewheeling clutches to intermediate clutch disabled positions to thereby realize optimum utilization of the ribbon and tape capacities.
