摘要

PROBLEM TO BE SOLVED: To provide an inkjet head which can realize a stable discharge of ink droplets, and to provide an inkjet discharging device, an inkjet recording device, and an inkjet discharging method.;SOLUTION: This inkjet recording device is equipped with a holding means 21 which holds a liquid, a sound wave generating means, and a sound wave converging means. In this case, the sound wave generating means is provided in a manner to be confronted with the liquid surface of the liquid being held by the holding means 21 through the liquid, and individually emits a plurality of sound waves to the liquid. The sound wave converging means converges respective sound waves to a plurality of positions of which the distances from the sound wave generating means are different. Liquid droplets are made to fly from the liquid surface of the liquid by individually converging respective sound waves by the sound wave converging means.;COPYRIGHT: (C)2007,JPO&INPIT
