Abstract
DISPOSITIVO PARA HACER PIVOTAR, BAJO CONTROL ELECTRODINAMICO, UN ESPEJO DE UN REPRODUCTOR OPTICO DE DISCOS DE VIDEO. EL DISPOSITIVO EN CUESTION ES POCO SUSCEPCIBLE A CAMPOS MAGNETICOS EXTERIORES Y COMPRENDE UN BASTIDOR (4) CON PESTAÑA (5) PROVISTA DE ABERTURA (6) PARA MONTAJE DEL DISPOSITIVO EN UN REPRODUCTOR. EL ESPEJO (1) PIVOTA ALREDEDOR DEL EJE (7) POR MEDIO DE UN APOYO (8) PEGADO A LA BASE (2) DEL ESPEJO Y UN SOPORTE (9), CON RANURAS (10, 11) ENSAMBLADO A DICHO APOYO (8). LAS RAMAS (10, 11) PENETRAN EN LA ABERTURA (13) DEL BASTIDOR DE MODO QUE EL REBORDE (14) SE APLIQUE A LA RANURA (12). EL SOPORTE (9) QUEDA FIJADO AL BASTIDOR, MEDIANTE PLACA (15), AL DEFORMAR LAS RAMAS (10, 11) UNA VEZ INTRODUCIDA LA PLACA (15) EN ESTAS.
