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 change level and reverse direction and be presented for storage upon the take-up roll. A partitioning plate in the ribbon cassette separates the supply roll from the take-up region of the cassette. Ink particles are thereby prevented from migrating from the post-printing, take-up region of the cassette to the pre-printing, supply region thereof.
