Abstract
L'INVENTION CONCERNE UN APPAREIL DE COMMANDE D'OBJECTIF. ELLE SE RAPPORTE A UN APPAREIL QUI COMPREND DEUX ORGANES MAGNETIQUES 12, 12 DONT UNE EXTREMITE EST RELIEE PAR UN AIMANT 11 CREANT UN FLUX MAGNETIQUE QUI PASSE DANS UN ORGANE MOBILE 15. DEUX ENROULEMENTS 14, 14 SONT FORMES SUR LES EXTREMITES DES ORGANES MAGNETIQUES 12, 12 QUI SE TROUVENT EN FACE DE L'ORGANE MOBILE 15 SI BIEN QUE DES COURANTS CIRCULANT DANS LES ENROULEMENTS PROVOQUENT UN DEPLACEMENT DE L'ORGANE 15. UN OBJECTIF EST SOLIDAIRE DE L'ORGANE 15 ET SA POSITION EST AINSI REGLEE. APPLICATION A LA CORRECTION DE L'ERREUR D'ALIGNEMENT DE L'OBJECTIF D'UN APPAREIL DE LECTURE DE VIDEODISQUES.
