ABSTRACT:
A compact ribbon cassette for dispensing and storing a ribbon or tape. The supply and take-up rolls of ribbon or 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 to be presented for storage upon the take-up roll. The ribbon cassette also includes a partition disposed between the supply and take-up rolls for preventing ink particles in the take-up portion of the housing from migrating and thereby contaminating the printing ribbon.
