Abstract

Dispositif de commande d'une tête d'impression par points. Il comprend une aiguille 10 d'impression fixée à une armature 12 qui est soumise à des forces magnétiques produites par des bobines 14 et 15, et à une force mécanique produite par un ressort 18. Les forces magnétiques et la force mécanique coopèrent pour projeter l'aiguille 10 en position d'impression. Un aimant permanent 16 exerce un champ magnétique dont le sens provoque le retour de l'armature et de l'aiguille 10 en position de repos. Domaine d'application : imprimantes par points.
