ABSTRACT:
An ink ribbon cassette apparatus which eliminates slack in an ink ribbon when the ink ribbon cassette is loaded on a printer. The ink ribbon is supplied from a supply reel and taken up on a take-up reel both supported on the cassette. A detector detects when the cassette is loaded on the cassette apparatus and in turn drives the take-up reel to draw a short length of the ink ribbon onto the take-up reel. The rotatable supply member is restrained by spring tension from rotating and from supplying the ribbon, providing a back tension on the ink ribbon and preventing slack.
