Abstract

Sistema de transporte de cinta magnética, empleado en un magnetófono o registrador de casete para uso juntamente con casetes normalizadas, las denominadas "casetes compactas". Los medios de accionamiento de cinta para el transporte del a cinta magnética en la casete, comprenden dos ejes de arrollamiento, los cuales cooperan con los dos cubos de arrollamiento. Uno de esos ejes de arrollamiento acciona a un dispositivo de impulsos a través de una correa, cuyo dispositivo consiste en un disco en el cual hay formadas aberturas. Una fuente de radiación, en forma de una lampara de incandescencia, está dispuesta en uno de los lados del disco y un elemento sensible a la radiación, en forma de un fototransistor, en el otro lado.
