ABSTRACT:
A compact ribbon cassette for dispensing and storing a ribbon or tape. The supply and take-up rolls of ribbon and tape are disposed upon a common rotatable shaft mounted for rotation within the housing. A unique chevron disposed adjacent the take-up roll and on the post-printing portion of the cassette causes the dispensed ribbon to reverse direction and change level and be presented for storage upon the take-up roll. Ink particles are removed by a wiper from the ribbon prior to printing.
