Abstract

Mecanismo de accionamiento para una impresora de matriz de puntos, que comprende una armadura, un alambre púa fijado con la armadura para moverse con ella, un muelle pre cargado para actuar sobre la armadura y un medio electromagnético que cuando es excitado mueve la armadura contra la acción de dicho muelle, moviéndose la armadura , cuando es des-excitado el medio electromagnético bajo la acción de dicho muelle con el fin de que el alambre o púa se desplace hacia el papel, limitándose la amplitud del recorrido de la armadura bajo la acción del muelle de tal modo que solamente la inercia de la armadura y el alambre o púa produzca el impacto del alambre o púa con el papel.
