Abstract: A cassette for a strip such as a tape or film, having a pair of spools between which the strip is wound and unwound, is provided with apparatus for counting and limiting the number of times the cassette is played. A feeler assembly is mounted for swinging movement on the cassette cover, between the rolls of strip on the spools, and has two feelers one of which rides on the outer periphery of one roll and the other of which rides on the outer periphery of the other roll. Upon winding and rewinding of the strip, therefore, the feeler assembly oscillates, and in doing so, it actuates an escapement which turns a toothed wheel. The toothed wheel, turning one unit of angular movement with each play of the cassette, records the number of plays by the rotated position of the wheel, which can be read through a window of the cassette, in the form of numerals on the wheel.
