ABSTRACT:
A replaceable cartridge containing an endless loop ink ribbon for use in printing units. The ribbon storage area inside of the cartridge is configured to guide the ribbon so that a large amount of ribbon may be stored in the allowed space while retaining favorable ribbon feed characteristics. The ribbon is guided by ledges formed on the inside surfaces of the cartridge between the ribbon inlet and outlet openings. The cartridge is to be constructed in halves and is designed with such symmetry that the halves are identical and so may be produced by the same tool or machine.
