Abstract
In a line-type printer head, a plurality of head chips are arranged side by side in a printing direction, and each of the head chips has a plurality of discharging portions aligned in the printing line direction so as to discharge ink droplets. A plurality of discharging portions of the adjoining head chips are placed in an overlapping section, and the landing interval between ink droplets discharged from the discharging portions in the overlapping section of one of the adjoining head chips and the landing interval between ink droplets discharged from the discharging portions in the overlapping section of the other head chip are different from each other.
Claims28
A printer head in which a line head is constituted by a plurality of head chips arranged side by side in a printing line direction, and each having a plurality of discharging portions aligned in the printing line direction so as to discharge an ink droplet, wherein a plurality of discharging portions of a first head chip and a second head chip placed at an adjoining portion therebetween are placed so as to overlap, and the landing interval between ink droplets discharged from said discharging portions in an overlapping section of said first head chip and the landing interval between ink droplets discharged from said discharging portions in an overlapping section of said second head chip are different from each other.
