Abstract

SE DESCRIBE UN APARATO DE MEDIDA DE RECORRIDO, DE ANGULO O ROTACION OPTOELECTRONICO, CON UN PORTADOR DE CODIGO DE ILUMINACION PROPIA O ALUMBRADO, EQUIPADO AL MENOS DE UNA PISTA DE CODIFICACION CON CAMPOS OSCUROS Y CLAROS SOBRE EL PORTADOR DE CODIGO, DE UN DISPOSITIVO DE DIAFRAGMA DISPUESTO JUNTO AL PORTADOR DE CODIGO EN FORMA DE UNA PLACA CON LA ZONA TRANSPARENTE A LA LUZ DISPUESTA EN LA PISTA DE CODIGO Y UN SENSOR OPTOELECTRONICO SOBRE LA CARA APARTADA DEL PORTADOR DE CODIGO DEL EQUIPO DE DIAFRAGMA CON LA SUPERFICIE DE SENSOR SENSIBLE A LA LUZ Y DIRIGIDA HACIA ELLA. EL EQUIPO DE DIAFRAGMA DEJA PASAR LA LUZ INFLUENCIADA POR LA PISTA DE CODIGO, CON LO QUE EL DISPOSITIVO DE DIAFRAGMA EN FORMA DE PLACA SOBRE LA CARA DIRIGIDA AL PORTADOR DE CODIGO DISPONE DE UN CHIP SEMICONDUCTOR OPTOELECTRONICO COMO SENSOR CON EL LUGAR DE CONTACTO DIRIGIDO A LA PLACA. EL EQUIPO DE DIAFRAGMA ADEMAS PORTA SOBRE SU CARA LOS LUGARES DE CONTACTO DE LAS PISTAS CONDUCTORAS ELECTRICAS QUE HACEN CONTACTO CON LOS LUGARES DE CONTACTO CORRESPONDIENTES DEL CHIP SEMICONDUCTOR.
