Abstract
Abstract Apparatus which is used for rapidly increasing and controlling the speed and stopping rotating reels in a tape deck assembly. The speed of the rotating wheels being regulated by a system of motors and a braking system which is made effective by an electrical control system which is actuated by a mechanical switch. The mechanical switch being part of a console housing the tape deck.
