Abstract

Perfeccionamiento en dispositivos de medición, del tipo que comprenden, una caja y una cinta enrollable alargada, un elemento de medición obligado hacia un estado enrollado en la caja con un extremo fijado a la caja y un extremo libre destinado a moverse hacia la caja y en sentido contrario para recorrer una distancia que se desea medir: caracterizado porque se dispone una serie de marcas ópticas a intervalos constantes a lo largo de la cinta para indicar el paso de distancia cuando las marcas son irradiadas y la cinta se mueve con relación a la caja; un dispositivo sensor fotoeléctrico llevado por la caja y que funciona asociado con las marcas en la cinta para generar señales de salida a incremento constantes de distancia durante el movimiento de la cinta; y un dispositivo de lectura que funciona conectado al dispositivo sensor para convertir las señales en una indicación de la distancia recorrida por la cinta.
