<p>A cleaning device for a cassette-type tape recorder wherein a cassette shell (1) is provided with a longitudinally reciprocating bar (25) adjacent the edge of the shell normally aligned with the heads of the recorder in use, the reciprocating bar being provided with a number of cleaning pads (19) which contact and clean the heads and drive rollers in the tape recorder in a reciprocating manner. In the preferred form of the invention three cleaning pads (19) are provided to clean the erase head, the record/playback head, and the capstan and pinch roller respectively. The bar is reciprocated by a cam drive (14, 15, 16) from a hub member (3) rotated by a drive spindle in the tape recorder. In the preferred form of the invention two hub members (3, 8) are provided, one being engaged with the forward take-up spindle and the other with the reverse take-up spindle of the tape recorder so that the cleaning device can operate either way up or in conjunction with an auto-reverse tape recorder regardless of the playing direction engaged.</p> |
