Abstract

La présente invention a trait à un appareil d'impression comportant un ensemble de supports 30, montés librement dans un châssis 12 et supportant des éléments d'impression 14 déplacés axialement à travers celui-ci par un dispositif électromagnétique 92, 94, 98 pour effectuer une impression sur un support d'enregistrement adjacent Les supports 30, 50 peuvent se déplacer librement par rapport au chassis 12 à la suite du déplacement non axial des éléments d'impression 14 pour en sortir la flexion ou les vibrations et réduire ainsi, voire éliminer, la rupture par fatigue qui en résulte.The present invention relates to a printing apparatus comprising an assembly of supports 30, freely mounted in a frame 12 and supporting printing elements 14 moved axially therethrough by an electromagnetic device 92, 94, 98 to effect printing on an adjacent recording medium The mediums 30, 50 can move freely relative to the frame 12 as a result of the non-axial movement of the printing elements 14 to remove bending or vibration therefrom and thereby reduce or even eliminate , the resulting fatigue failure.
