Abstract
A top loading ribbon cartridge having a threaded ribbon guide for directing ribbon in the cartridge out of and back into the cartridge which is mountable on one side of a machine printing point. The threaded ribbon guide is movable relative to the cartridge from a retracted position away from the printing point to an extended position to expose ribbon in front of the printing point incident to typing actions. The movement of the ribbon guide is in a lateral direction which permits the mounting of a similar cartridge on the opposite side of the printing point which may contain error correction ribbon or ribbon of a different color in readiness for operation under operator control.
