Abstract

PROBLEM TO BE SOLVED: To wash off foreign matter in an ink jet head by washing after cutting. SOLUTION: In a washing method, the vibration plate forming one of the walls of an ink chamber is displaced to pressurize the ink in a pressure chamber to jet ink from the nozzles communicating with the pressure chamber. An ink jet head is arranged in a washing soln. container 4 housing a washing soln. so that nozzles are turned downwardly and a tube 5 comes to an ink supply port through a jig 10 and the washing sol. container 4 is put in an ultrasonic washing machine 9 and the washing soln. in the washing soln. container 4 is passed through the ink jet head by a liquid feed pump 7 while ultrasonic waves are applied to the ink jet head and the ink jet head is washed while the waste washing soln. is sent to a waste soln. container 8.

Description of the Related Art A vibrating plate forming one of the walls of an ink chamber is displaced by utilizing displacement in the thickness direction of a laminated piezoelectric element to pressurize ink filled in the pressure chamber and communicate with the nozzle. An inkjet head 1 that ejects more ink is shown in FIG. The outline of the structure is as shown in FIG. 7, in which a laminated piezoelectric material is bonded onto a rigid member 109 and grooves are formed on the surface of the laminated piezoelectric material to form a plurality of laminated piezoelectric elements 107 that can be independently driven, and ink is formed. A nozzle 111 for displacing a vibrating plate 103 forming one wall of the chamber 102 to pressurize the ink filled in the ink chamber 102 to communicate with the ink chamber 102.
More ink droplets are ejected. This structure is intended to increase the amount of displacement in the thickness direction by stacking piezoelectric bodies and consequently to arrange the ink chambers at a high density. Further, the laminated piezoelectric element 107 is electrically connected to the electrode pattern 108 formed on the vibrating plate 103 and the rigid member 109 for the purpose of facilitating driving from the outside.
