Abstract
Perfeccionamientos en los sistema de control electrónicos para aparatos de grabación y/o reproducción del tipo reversible, en los que un relé controla el accionamiento mecánico de la inversión del sentido de avance de la cinta, caracterizados porque el sistema comprende: un detector del movimiento del disco, teniendo como su salida un nivel de lógica de 0 o 1 según al estado de reposo o de movimiento del disco, un primer bloque de lógica, que responde a la salida de dicho detector del movimiento de dicho disco, y que tiene como su salida un nivel de lógica de 1 o 0 según si el disco está parado pero antes giraba, o según si el disco está parado pero antes ya estaba parado y un multi vibrador mono estable que responde a la salida de dicho primer bloque de lógica y es pato para proporcionar como su salida en cada transición de su entrada de 1 a 0 un impulso de control para dicho relé de inversión del sentido de avance de la cinta, siendo tal la disposición que se obtiene una inversión del sentido de avance de la cinta cada vez que el disco se detiene porque la cinta llega al final de su recorrido.
