ABSTRACT:
A thermal ink ribbon cassette for holding an inked ribbon of indefinite length for is in a thermal transfer printing mechanism is disclosed in which the cassette holds a spool of fresh ink ribbon which passes out of the cassette and across a thermal printing head, and then back into the cassette into a used ribbon chamber. A ribbon drive mechanism is mounted in the cassette adjacent the location on the cassette where the used ribbon normally enters the cassette so that if the ribbon breaks, the free broken end can be manually fed into the drive mechanism so that the remaining portion of the unused ribbon can be used. The cassette may also be provided with a removable front wall so that replacement ribbons can be inserted by a user, and a disposable container can be put into the ribbon take up chamber of the cassette so that a user does not have to handle the rumpled ink ribbon when changing to a new ribbon.
