Abstract

La présente invention a trait à un appareil d'impression dans lequel plusieurs éléments d'impression oblongs 14 montés dans un châssis 12 sont déplacés dans le sens de longueur par un dispositif électromagnétique pour effectuer une impression sur un support d'enregistrement placé côté extrémité d'impression des éléments d'impression 14. Des supports d'éléments d'impression 26, 29, 28, 27 montés dans le châssis 12 orientent les éléments d'impression 14 de telle sorte que leurs axes soient pratiquement dans le même plan et parallèles les uns aux autres sur une partie de leur passage à travers le châssis entre le support 27 et le palier 36 afin d'eliminer la pression latérale appliquée aux éléments d'impression par le palier d'extrémité 36 de la tête d'impression matricielle.
