ABSTRACT:
A tape cassette playback machine with a playback head utilizes a forward drive pinion, a pressure roller and capstan to drive audio tape in a cassette in forward direction past the playback head to cause the intelligence on the audio tape to be played out by the playback machine. It utilizes a reverse drive pinion to rewind the audio tape within the cassette. These drive pinions mesh with forward and reverse cassette drive sprockets, respectively, which are integral with the forward and reverse tape takeup reels within the cassette. The outer case of a cassette phrase retriever is situated over the tape cassette in the playback machine, and has a rotatably mounted reverse drive spider or pinion extending downwardly from it into driving relationship with respect to the cassette reverse drive sprocket. Manually operable mechanism is provided in the retriever for selectively driving the reverse drive spider in rewind direction through any one of several preselected angular distances thus to cause the tape within the cassette to back up past the playback head in the playback machine for any one of a plurality of preselected linear distances. This manually operable mechanism is disengaged from the reverse drive spider when not in operation, thus to let the spider turn freely with the cassette reverse drive sprocket during normal forward or rewind movement of the tape through the playback machine.
