Description

ABSTRACT:
A ribbon cartridge for a printer provides an unsupported length of ribbon between a pair of spaced guide means to provide for easy threading. In addition, continuous rotation of the ribbon is made possible by storing the ribbon as an endless loop in a random fashion in the principal cavity of the cartridge. A secondary cavity prevents an accidental loop from coming out of the cartridge which would otherwise result in slack in the unsupported length.
