Abstract

APARATO PARA COMPROBAR LA CALIDAD DE IMPRESION DE EQUIPOS PREFERIBLEMENTE IMPRESORES DE MATRIZ O DE CHORRO DE TINTA. COMPRENDE UN DIODO FOTOEMISOR (7) UNA FILA DE FOTODIODOS (8) QUE SON LEIDOS POR UN MECANISMO DE CONTROL (12) INCLUIDO EN UN ORDENADOR (6). LA SEÑAL DESDE CADA FOTODIODO ES TRANSFERIDA A UNOS COMPARADORES (5) EXISTIENDO UN AMPLIFICADOR DE CORRIENTE CONTINUA (F) UNA FUENTE DE TENSION DE REFERENCIA (R) Y UN AMPLIFICADOR DIFERENCIAL (D). FINALMENTE EXISTE UN CONTADOR (9) UN REGISTRO (10) DE PUNTOS Y UN CIRCUITO DE SEÑALES (11) PARA DAR UNA SEÑAL DE ALARMA.
