<P>PROBLEM TO BE SOLVED: To provide an inkjet head capable of preventing the occurrence of a crosstalk at ejection of an ink droplet. <P>SOLUTION: The inkjet head includes a plurality of drive columns arranged in parallel through a groove and functioning as a piezoelectric driving mechanism, and a plate having a plurality of diaphragms bonded to a pillar end surface of each drive column with adhesives. Then, the inkjet head vibrates a diaphragm to eject the ink droplet. The drive column includes a receiving means for receiving surplus adhesives generated when the diaphragm and the drive column are bonded to a pillar end. Accordingly, the wet spreading of the adhesives to the adjacent piezo element is prevented, and the adhesives are controlled so as to be wet and spread in a direction without an adjacent piezo element, and thereby the occurrence of the crosstalk is prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
