PURPOSE:To give an ink feed smoothly to produce a picture with regularity by a method wherein a plurality of outlets are perforated in one row in the ink feed pipe disposed in the ink chamber to allow the injected ink to diffuse in the ink chamber. CONSTITUTION:An ink jet printing multi-nozzle head comprises a multi-nozzle unit 9, a vibrating plate unit 11 positioned in facing thereto and an ink chamber 9b. A plurality of ink outlets 8a are provided in one row for the pipe 8 which feeds the ink into one or two ink chambers disposed within the ink chamber 9b of the multi- nozzle head, allowing the outlet 8a to face to the direction not to cross with the vibration transmission range to permit the ink injected from the ink outlet 8a to diffuse entirely. This enables to eliminate the ink sediment in the ink chamber 9b, preventing the degradation of the ink and preventing the solid matter within the ink from sticking to the vibrating plate. |
