Abstract

Un lecteur 1 est prévu pour lire des lignes de données parallèles formant, avec son substrat (2), une bande de données (3). Le lecteur (1) comprend des moyens d'allignement (5) pour maintenir la bande et des moyens d'analyse sur un chassis qui se déplace tout en analysant de façon synchrone les lignes de données. Une source de lumière infrarouge illumine la ligne de données à analyser et des lentilles cylindriques disposées en croix, focalisent des bits analysés individuels sur un détecteur infrarouge correspondant.
