Abstract

Cette imprimante à matrice en points comprend une armature 17 reliée à une aiguille 14 dont l'extrémité vient en contact, en service, avec la surface d'une bande de papier. Un ressort 25 pré-chargé agit sur l'armature et un dispositif électro-magnétique, lorsqu'il est excité, déplace cette armature contre l'action du ressort. L'armature se déplace sous l'action du ressort lorsque le dispositif électromagnétique n'est plus excité, et entraîne l'aiguille vent le papier. La course de l'armature, sous l'action directe du ressort est limitée de sorte que seules son inertie et celle de l'aiguille provoquent le choc de l'aiguille sur le papier.
