ABSTRACT:
A cartridge for an endless band printer ribbon includes a chamber for storing the ribbon in a convolute therewithin. One or more segments of the ribbon are maintained exteriorly of the cartridge to overlie and close the open end of a corresponding depression(s) formed in the cartridge's periphery to form a protrudent member-receiving compartment. The number of depressions corresponds to the number of protrudent ribbon guides (rollers, posts, etc.) in the printer. The protrudent member-receiving compartments are positionable so that their corresponding guides may be simultaneously received therein. After such reception, the cartridge is moved away from the guides, which thereupon engage and withdraw the ribbon from the convolute by unwinding it until the cartridge is mounted to the printer and a portion thereof is properly adjacent a printing location on a platen. The cartridge may also contain a one-way clutch to effect unidirectional ribbon movement and a ribbon re-inker.
