Abstract

Dispositivo de lectura de caracteres impresos compuestos por una pluralidad de elementos separados por espacios de un primero y de un segundo tipos según un código dado de los caracteres, dispositivo que comprende una cabeza de lectura concebida para detectar la presencia de los elementos de un carácter colocados sucesivamente delante de la cabeza, y un circuito de identificación que comprende medios de identificación del comienzo y del final de un carácter, y de los dos tipos de espacio entre elementos consecutivos, caracterizado porque la cabeza de lectura comprende tres detectores de elementos de los que un primero y un segundo están separados por una distancia igual al primer tipo de espacio, y de los que el primero y un tercero están separados por una distancia igual al segundo tipo de espacio, estando unidos respectivamente los medios de identificación del comienzo y del final de un carácter con el primer detector y, con el primero y tercer detectores, y estando respectivamente unidoslos medios de identificación de los dos tipos de espacio con el primero y segundo detectores, y, con el primero y tercer detectores, dispositivo de lectura que comprende además unos medios de memorización de una información codificada que representa un carácter leído, estando unidos estos medios al conjunto de los medios de identificación, de modo que la información codificada memorizada en los medios apropiados resulte de la detección de un primer elemento de un carácter por el primer detector, de los elementos consecutivos del carácter simultáneamente por el primero y el segundo detectores, y por el primero y el tercer detector, y de la detección de un último elemento del carácter por el tercer detector.
