Title: Ink-jet line head
Inventor: KOEDA SHUJI
IPC: B41J2/16
Filed: 2001-02-15
Abstract: PROBLEM TO BE SOLVED: To prevent ink discharge characteristics from deteriorating by securing proper pitch of nozzle holes at a connecting part when a line ink jet head is formed by connecting a plurality of ink jet heads, and improve the yield, enable a flow at a manufacturing apparatus for small-diameter wafers, and reduce manufacturing costs and equipment investment for a line head provided with a considerably large number of nozzle holes. SOLUTION: A pitch of discharge chambers 21 is reduced to be smaller than the pitch of nozzle holes 11, whereby a thickness increase of a diaphragm of the head joint part 50 is absorbed. When the pitch of the nozzle holes is represented by P1, the number of nozzle holes of a single head chip 100 is represented by N, a thickness of the diaphragm 27 of a general part is represented by T1, and a thickness of the diaphragm of the head joint part 50 including an adhesive layer 28 is represented by T2, P2=P1-(T2-T1)/N is satisfied because the pitch P2 is reduced by a length obtained by dividing the thickness increase of the diaphragm generated at both ends of the head chip 100 by the number N of nozzle holes.
