RIBBON CARTRIDGE CAPABLE OF PROVIDING A TENSION FORCE TO A RIBBON AT ONE END OF A RIBBON-FEEDING BAY

摘要

A ribbon cartridge provides a tension mechanism to a ribbon inside the cartridge. By installing a frictional piece on one end of a ribbon-feeding bay of the ribbon cartridge, a feeding roller contacts the frictional piece and the frictional piece provides a frictional force for applying sufficient tension on the ribbon.
