Abstract

DISPOSITIVO PARA IMPRIMIR CARACTERES ALFABETICOS Y NUMERICOS SOBRE UN DOCUMENTO ALIMENTADO A SU PASO (1) DE TRANSFERENCIA DE PAPEL, COMPRENDIENDO AL MENOS UNOS MEDIOS PARA DETECTAR EL DOCUMENTO, DOTADOS DE UN FOTOEMISOR (U1) Y UN FOTODETECTOR (Q1) SITUADOS EN EL PASO (1) DE MODO QUE UN DOCUMENTO ALIMENTADO A UN CAMINO DE PROPAGACION DE LA LUZ ENTRE EL FOTOEMISOR (U1) Y EL FOTODETECTOR (Q1) ORIGINE UN CAMBIO EN LA CANTIDAD DE LUZ RECIBIDA POR EL FOTODETECTOR (Q1). LA ALIMENTACION DEL DOCUMENTO SE DETECTA CON MEDIOS OPTICOS (2; 3) MONTADOS EN EL CAMINO DE PROPAGACION DE LA LUZ ENTRE EL FOTOEMISOR (U1) Y EL FOTODETECTOR (Q1), Y SITUADOS DE MODO QUE HAGAN QUE LA LUZ SE PROPAGUE VARIAS VECES POR EL PASO (1) ANTES DE INCIDIR SOBRE EL FOTODETECTOR (Q1).DEVICE TO PRINT ALPHABETICAL AND NUMERICAL CHARACTERS ON A DOCUMENT FEED AT ITS STEP (1) OF PAPER TRANSFER, INCLUDING AT LEAST ONE MEANS TO DETECT THE DOCUMENT, EQUIPPED WITH A PHOTOEMISOR (U1) AND A PHOTO SENSOR (U1) 1) SO THAT A DOCUMENT SUPPLIED TO A LIGHT PROPAGATION PATH BETWEEN THE PHOTO EMITTER (U1) AND THE PHOTODETECTOR (Q1) ORIGINATES A CHANGE IN THE AMOUNT OF LIGHT RECEIVED BY THE PHOTODETECTOR (Q1). THE FEEDING OF THE DOCUMENT IS DETECTED WITH OPTICAL MEANS (2; 3) MOUNTED ON THE PATH OF PROPAGATION OF LIGHT BETWEEN THE PHOTO EMITTER (U1) AND THE PHOTODETECTOR (Q1), AND SITUATED SO THAT THEY PROPAGATE LIGHT SEVERAL TIMES BY STEP (1) BEFORE IMPACTING ON THE PHOTODETECTOR (Q1).
