Abstract

EL OBJETO DE LA INVENCION ES UN DISPOSITIVO DE PALPACION OPTICO PARA LA LECTURA DE SIMBOLOS DE CODIGOS DE BARRAS, EN EL CUAL UN RAYO LUMINOSO EMISOR QUE PARTE DE UN EMISOR DE LUZ ES DIRIGIDO MEDIANTE UN DISPOSITIVO DE ENFOQUE A UN POLIGONO DE MULTIPLES FACETAS Y DESDE ESTE ES ORIENTADO A UNA MANCHA DE LUZ PEQUEÑA SOBRE UN PLANO DE LECTURA, DESDE EL QUE, DEBIDO A LA DIFERENTE REFLEXION DE LAS BARRAS Y DEL FONDO DE UN SIMBOLO DE CODIGO DE BARRAS, LLEGA UN RAYO RECEPTOR QUE PRESENTA UNA MODULACION DE POTENCIA A TRAVES DE UNA OPTICA DE RECEPCION A UNA UNIDAD DE EVALUACION, EN DONDE TIENE LUGAR LA INVERSION, TANTO DEL RAYO LUMINOSO EMISOR COMO TAMBIEN DEL RAYO LUMINOSO RECEPTOR, A TRAVES DE LA MISMA FACETA DEL POLIGONO Y EN DONDE EL DISPOSITIVO DE ENFOQUE (5) ESTA DISPUESTO PERIODICAMENTE DESPLAZABLE A LO LARGO DEL RAYO LUMINOSO EMISOR (3).
