Abstract

Dispositif pour le montage du phonocapteur d'un tourne-disques à l'aide d'un court bras porteur prévu pour la tête de lecture en cas de guidage tangentiel. Le dispositif comporte des organes magnétiques 7, 8 qui, en exerçant des forces magnétiques, empêchent le bras 1, supporté mécaniquement en un point 4 seulement, de se mouvoir dans un plan vertical s'étendant dans la direction d'un rayon du disque, alors que le bras 1 peut, sans guides mécaniques, se mouvoir librement dans un plan vertical tangentiel aux sillons et dans un plan parallèle au disque. L'invention est applicable une manière générale à des tourne-disques.
