Claims (8)

  1. Tête d'enregistrement du type à jets d'encre ayant plusieurs buses (190-197) destinées à projeter des gouttelettes d'encre, dans laquelle
    les buses (190-197) sont disposées de manière qu'elles soient positionnées sur des droites (L1, L2) avec un intervalle, les droites étant inclinées mutuellement en sens opposés par rapport à une direction de balayage principal (x) qui correspond à une direction de transport de la tête d'enregistrement, et des arrangements de buses sont formés avec une configuration pratiquement en V, dans laquelle :
    un arrangement au moins de buses positionnées sur l'une des droites inclinées (L2) subit un décalage de position dans la direction de balayage principal (x) par rapport à l'autre arrangement de buses,
    caractérisée en ce que
    l'amplitude de décalage (d2) entre le premier arrangement de buses et l'autre arrangement de buses dans la direction de balayage principal est réglée à un nombre entier du pas d'impression (P1) de chaque buse dans la direction de balayage auxiliaire (y) perpendiculairement à la direction de balayage principal (x).
  2. Tête d'enregistrement du type à jets d'encre selon la revendication 1, dans laquelle l'amplitude de décalage (d2) dans la direction de balayage principal (x) est réglée afin que chaque buse (190, 192, 193, 194) de l'autre arrangement de buses soit placée entre les buses (191, 195, 196, 197) du premier arrangement de buses.
  3. Tête d'enregistrement du type à jets d'encre selon la revendication 1 ou 2, dans laquelle l'amplitude de décalage (d2) dans la direction de balayage principal est égale à 2,5 fois l'intervalle (d1) entre les buses (190-197) dans la direction de balayage principal ou est égale à cet intervalle.
  4. Tête d'enregistrement du type à jets d'encre selon l'une quelconque des revendications 1 à 3, dans laquelle l'une des buses (2) a une position séparée par un espace d'une partie de bord d'une chambre d'encre (17) sur la droite inclinée sur le côté de la partie courbée.
  5. Tête d'enregistrement du type a jets d'encre selon l'une quelconque des revendications 1 à 4, dans laquelle des chambres d'encre (170-177) qui communiquent avec les buses (190-197) sont réalisées avec une surface courbe à gradin près des buses (190-197) telle que le diamètre de la surface courbe est plus petit près des buses (190-197).
  6. Tête d'enregistrement du type à jets d'encre selon l'une quelconque des revendications 1 à 5, dans laquelle les arrangements de buses sont disposés avec une forme de losange.
  7. Tête d'enregistrement du type à jets d'encre selon l'une quelconque des revendications 1 à 6, dans laquelle la tête d'enregistrement du type à jets d'encre est du type empilé tel que les positions entre les chambres d'encre (170-177) et les buses (190-197) sont variables.
  8. Tête d'enregistrement du type à jets d'encre selon l'une quelconque des revendications 1 à 7, dans laquelle les chambres d'encre (170-177) sont placées perpendiculairement à chacune des droites (L1, L2).
