Abstract

L'INVENTION CONCERNE UN APPAREIL POUR POSITIONNER ET AJUSTER VERTICALEMENT UNE TETE MAGNETIQUE PAR RAPPORT A UNE SERIE DE PISTES HORIZONTALES PARALLELES FORMEES SUR UN SUPPORT D'ENREGISTREMENT TEL QU'UNE BANDE MAGNETIQUE VIDEO. UNE TETE MAGNETIQUE EST MONTEE A UNE EXTREMITE D'UNE COLONNETTE-SUPPORT MOBILE VERTICALEMENT DONT L'AUTRE EXTREMITE EST EN CONTACT CONTINU AVEC L'UN DES GRADINS HORIZONTAUX PLANS FORMES SUR LA SURFACE D'UNE CAME MONTEE ROTATIVE. UN DISQUE INDICATEUR DE POSITION EST FIXE A LA CAME ET EST RELIE A UNE ALIMENTATION ELECTRIQUE ET A DES MOYENS DE DETECTION, LE DISQUE COMPORTANT AU MOINS DEUX TRAJETS DE SIGNALISATION ET UN CIRCUIT LOGIQUE AGENCE POUR COMMANDER LA ROTATION VERS L'AVANT ET L'ARRIERE DE LA CAME, CE QUI PERMET DE COMMANDER AVEC PRECISION LA POSITION DE LA TETE MAGNETIQUE.
