ABSTRACT:
A compact ribbon cassette for dispensing and storing a ribbon or tape upon integrally formed dispensing and storage spools. The dispensing and storage spools are disposed upon a common rotatable shaft mounted for rotation within the housing. An integral, self-adjusting friction plate bears upon the ribbon on the dispensing spool and provides a predetermined, varying drag to maintain uniform ribbon taughtness.
