ABSTRACT:
A cleaning cassette for cassette recorders in which movement of either spindle of the cassette recorder operates a cleaning element within the cassette casing. Transmission of the rotary movement is achieved by a pair of rotatably mounted reel hubs and a pair of exterior toothed wheels, one integral with each hub, with the reel hubs coupled together by a third intermediate exterior toothed wheel to form a permanent gear train. For driving a cleaning element, such as a felt tab, the intermediate wheel drives a cam and lever. By rotating either toothed wheel, the intermediate wheel causes the lever to move the tab alternately back and forth substantially parallel to the front edge of the cassette casing.
