Abstract

EL TECLADO CONSTA DE UNA MATRIZ DE TECLAS (1), UNA SERIE DE DIODOS ELECTROLUMINISCENTES (2), Y UNA SERIE DE FOTODIODOS (3). A CADA DIODO SE HALLA ASOCIADA UNA COLUMNA, A LO LARGO DE LA CUAL LA RADIACION LUMINOSA SE PROPAGA EN UN CANAL HUECO (20). A CADA FOTODIODO (3) SE HALLA ASOCIADA UNA LINEA, A LO LARGO DE LA CUAL LA RADIACION LUMINOSA SE PROPAGA EN UNA BARRA (30) DE MATERIAL TRANSPARENTE. CADA BARRA (30) CONSTA DE ELEMENTOS DE DEFLEXION (4) DE LA RADIACION DE LOS DIODOS ELECTROLUMINISCENTES (2) HACIA EL FOTODIODO (3) CORRESPONDIENTE. HACIA ARRIBA DE CADA ELEMENTO DE DEFLEXION (3), EN EL TRAYECTO DEL HAZ LUMINOSO, Y EN RELACION DIRECTA CON EL DIODO ELECTROLUMINISCENTE (2) CORRESPONDIENTE, UNA COMPUERTA (5) DE INTERRUPCION DE LA RADIIACION ES CONTROLADA POR CADA TECLA (1). LOS DIODOS ELECTROLUMINISCENTES (2) SON CONTROLADOS DE MANERA SECUENCIAL Y CICLICA. EL TECLADO DEL INVENTO PERMITE, POR EJEMPLO LA ENTRADA MANUAL DE VALORES DADOS EN UNA MAQUINA DE TRATAMIENTO DE LA INFORMACION.
