Abstract

Tête d'impression de dimensions et de complexité réduites pour une imprimante à matrice de points dont les marteaux sont montés côte à côte entre seulement deux aimants primaires. La tête d'impression comprend des marteaux incluant chacun un corps dans lequel est montée une bobine pourvue d'une surface latérale en regard de la surface latérale correspondante de la bobine d'un marteau adjacent. Chaque bobine comprend un fil pourvu de deux parties extrêmes et d'une partie intermédiaire relativement éloignée des parties extrêmes, la partie intermédiaire formant une partie d'une spire intérieure de la bobine et les parties extrêmes partant de spires différentes de la bobine. Application aux imprimantes à matrice de pointsPrinthead of reduced dimensions and complexity for a dot matrix printer whose hammers are mounted side by side between only two primary magnets. The print head comprises hammers each including a body in which is mounted a spool provided with a side surface facing the corresponding side surface of the spool of an adjacent hammer. Each spool comprises a wire provided with two end parts and an intermediate part relatively distant from the end parts, the intermediate part forming part of an inner turn of the spool and the end parts starting from different turns of the spool. Application to dot matrix printers
