ABSTRACT:
The spools of a tape recorder are rotated to wind the tape in one direction or the other using a single motor. A reversible lever carries two friction wheels, one on either side of its pivot, and a band runs round these wheels and a driving pulley on the axis of the motor. The friction wheels are each mounted close to one of the spools. The lever is mounted so that it can pivot on its axis with less friction than there is in the bearings of the friction wheels, so that when the band reverses its direction of movement, the lever pivots to bring a different one of the friction wheels to bear against its respective spool, whereupon that spool is driven by friction between it and the friction wheel.
