Abstract

Sistema de lectura de caracteres codificados y materializados sobre un documento por sucesiones de agrupaciones de segmentos de anchura constante alineados a lo largo de un trayecto de lectura y separados entre sí, para definir un carácter dado, por intervalos elegidos dentro de un conjunto de n longitudes predeterminadas y reconocibles electrónicamente por detección de un fenómeno físico, principalmente magnético, por un tipo de captador apropiado, del tipo que comprende al menos una cabeza de lectura que incluye al menos un captador ya citado dispuesto frente a dicho trayecto de lectura así como un medio de arrastre que asegura un movimiento relativo entre dicha cabeza de lectura y dicho documento.
