摘要： Streak defects are reduced by making correction for each unit head even if there is variation in jet characteristic of ink droplet among unit heads and even if there is variation in arrangement accuracy of the unit heads. A liquid jet device comprises a line head (10) where (unit) heads (11) having liquid jet portions are arranged are arranged side by side. The liquid jet device further comprises jet direction changing means for changing the direction of jet of a liquid droplet jetted from a nozzle of each liquid jet portion into one of directions parallel to the direction of the arrangement of the liquid jet portions and reference direction setting means for setting one main direction used as a reference out of the jet directions of the liquid droplet changeable by the jet direction changing means individually for each unit head (11). The jet direction of the third liquid jet portion in each of the “N-1”-th and “N+1”-th heads (11) is the main direction, and the jet direction of the second liquid jet portion of the “N”-th head (11) is the main direction.

摘要： A line head that minimizes the influence of strain due to generation of thermal stress and minimizes the influence on printing results even when only the head chips are suddenly heated is provided. First strain-reducing portions 31 are formed in a nozzle plate by arranging at least one line of a plurality of holes in a direction perpendicular to an arrangement direction of nozzles 18 in regions near outer edges of end portions of head chips 11 in a longitudinal direction thereof. Second strain-reducing portions 32 are formed in the nozzle plate by arranging at least one line of a plurality of holes in the arrangement direction of the nozzles 18 from positions near the outer edges of the end portions of the head chips 11 in the longitudinal direction thereof toward central portions of the head chips 11 in the longitudinal direction thereof.

摘要： Even when ejection characteristics of ink droplets are dispersed between unit heads and when arrangement accuracies of unit heads are dispersed, stripe unevenness is alleviated by correction corresponding to each unit head. In a liquid ejection apparatus having a line head (10) arranged by juxtaposing a plurality of (unit) heads (11) of liquid ejection parts so as to connect the head (11) to the adjacent head (11), the liquid ejection apparatus includes ejection direction changing means for enabling the ejection direction of liquid droplets ejected from a nozzle of each liquid ejection part to change in a plurality of directions in the arranging direction of liquid ejection parts and reference direction setting means for individually setting one reference principal direction for each head (11) among a plurality of ejection directions of liquid droplets by the ejection direction changing means. In the (N-1)th and the (N+1)th head 11, the third ejection direction from the left is established as the principal direction while in the Nth head 11, the second ejection direction from the right is established as the principal direction.
