Abstract
A ribbon feeding mechanism for a typewriter or printer includes a pivotally mounted platform for removably receiving a fabric or carbon ribbon cassette. A manually operable lever carries ribbon feeding components including a toothed wheel for engaging the carbon ribbon takeup unit in the carbon ribbon cassette and a gear for engaging a driven gear of a fabric ribbon cassette. The ribbon feeding components are rotated about a common axis by a cam-driven pawl and rachet mechanism.
