Laminated ink jet recording head
摘要:
Nozzle openings 18-1, 18-2, 18-3, . . . are formed so as to stagger, and pressure generating chambers 7-1, 7-2, 7-3, . . . , communicating holes 10-1, 10-2, 10-3, . . . , and ink supply ports 12 are arranged at uniform positions relative to one another with respect to the pressure generating chambers 7-1, 7-2, 7-3, . . . so as to match a mode of arraying nozzle openings 18-1, 18-2, 18-3, . . . . As a result of this construction, a bonding area is increased by shifting the positions of the nozzle openings 18-1, 18-2, 18-3, . . . , whose diameter is particularly small, in an axial direction of the pressure generating chambers.
