Abstract

L'invention concerne un mécanisme de frappe pour imprimante. Elle se rapporte à un mécanisme qui comprend deux pièces polaires 46 et 56, délimitant des entrefers avec un organe élastique 16 de frappe au niveau des faces polaires 48 et 60, les deux pièces polaires étant reliées par un aimant permanent 54 et un organe 44 de couplage. Un enroulement 50 formé autour de la pièce polaire 46 permet la libération de l'élément 16 de frappe qui est normalement maintenu au contact de la pièce polaire 46 du fait du champ magnétique créé par l'aimant permanent 54. Application à la réalisation d'imprimantes par ligne.
