Abstract

PURPOSE:To obtain the titled device which is easy to assemble and efficient in forming ink droplets by providing a jetting nozzle in an ink chamber other than an ink supply passage in such a manner that it is not positioned on one straight line with a nozzle serving as a passage of ink flowing in and out. CONSTITUTION:A nozzle 8 is provided in the ink chamber 9 serving as the ink supply passage, while another nozzle 10 serving as the passage of ink flowing in and out is provided in a pressure chamber 11 applying pressure to ink, and the jetting nozzle 12 is provided in the ink chamber 9 in such a manner that it is not positioned on one straight line with the nozzle 10. Ink droplets can be formed even when the flow of ink branches from the pressure chamber 11 and thus assembling technologies of high precision is made unnecessary.
