Abstract
The device for automatically cleaning operating parts of a cassette tape deck is provided. The apparatus is enclosed in the frame of a standard cassette. Tape head cleaning is accomplished by a cleaning pad reciprocally moved across the tape head. An arm on which the pad is located is driven by cams powered by the take-up spindle of the tape deck. Capstan and pinch roller cleaning occurs when a second cleaning pad is spring biased against them as they turn. Solvents can be added to the cleaning pads to dislodge deposits.
