Abstract

a. Appareil de commande à miroir mobile suivant deux axes pour magnétoscope à disque. b. Dispositif caractérisé par un premier moyen magnétique fixé au miroir solidaire en pivotement de celui-ci, ainsi qu'un second moyen magnétique fixé rigidement à l'organe de support et écarté du premier moyen magnétique en etant polarisé par rapport au premier moyen magnétique pour créer un champ magnétique de verrouillage destiné à attirer le premier moyen magnétique pour pousser le miroir contre le support en évitant que le miroir ne tourne dans une troisième direction sur le support.
