A ribbon drive mechanism for a typewriter or similar machine in which the supply spool and a first ribbon guide are fixed with respect to the machine frame, and the take-up spool and a second ribbon guide are vertically moveable with respect to the machine frame. The ribbon is fed past the print point when the take-up spool and the second ribbon guide adjacent thereto are in their raised position. Means are also provided for feeding a constant increment of ribbon, regardless of the amount of ribbon on the take-up spool.
