ABSTRACT:
A cleaning cassette for a tape unit includes a supply reel and a take-up reel, with a cleaning ribbon mounted therebetween. The cleaning ribbon extends around various support surfaces in the cassette, and passes two cleaning stations. The first cleaning station utilizes a spring biased plunger to force the cleaning ribbon against a pinch roller being cleaned. A traction sleeve is positioned between the capstan and the pinch roller to enhance the frictional engagement between the capstan and the pinch roller. At the second cleaning station, the cleaning ribbon passes between the capstan and the pinch roller. Once again, a traction sleeve is provided between the capstan and the pinch roller, and in this case the traction sleeve is offset with respect to the cleaning ribbon. Funnel-shaped openings and distribution channels are provided in the said shell to introduce a liquid such as a cleaning solvent onto the cleaning ribbon near the cleaning stations. A ratchet mechanism is provided on the take-up reel to insure that the only motion of the ribbon is from the supply reel to the take-up reel.
