Abstract: An improved, disposable inexpensive feed mechanism is uniquely incorporated in a cassette having a flexible or movable wall (2a) driven by contact with a moving printer carriage or the like. Friction facing (7) of the moving wall cooperates with a fixed friction facing (9) on an interiorly placed portion (10) of a cassette wall (2b) with a ribbon (15) between the two friction faces. The friction facing of the movable part has angled fiber elements that engage the ribbon in one direction but slip easily over the ribbon in the opposite direction. The moving printer carriage (13) or the like contacts a movable portion (2f) of the cassette wall (2a) in each pass and indexes the ribbon slightly to provide a fresh supply across a platen. The entire mechanism is disposable, is contained in a single clean package and is very low cost. No rollers, feed roll drives or motors are required.
