Abstract
An ink ribbon feeder having a pair of rotatable ratchet wheels for driving ribbon spools. A control member rockable toward either ratchet wheel carries a ratchet wheel drive member movable on the control member for driving a respective one of the ratchet wheels to which the control member has been rocked. When ribbon from a spool has run out so that ribbon tension prevents further driving of a particular ratchet wheel, the control member rocks toward the other ratchet wheel to bring the ratchet wheel drive member into position to drive the other ratchet wheel and feed the ribbon in a reverse direction.
