发明名称 LIQUID EJECTION HEAD AND LIQUID EJECTOR
摘要 PROBLEM TO BE SOLVED: To provide a liquid ejection head which can eject desirable ink liquid droplets formed in minute liquid droplets, and to provide a liquid ejector. SOLUTION: A second nozzle 51B is set by separating a predetermined interval on an ink ejection direction side of a first nozzle 51A. A space between a surface where the first nozzle 51A is formed and a surface where the second nozzle is formed is made a lead-in channel 55. When the ink in a pressure chamber 52 is pressurized by operating a piezoelectric element 58 prepared in the pressure chamber, a part of the ink out of the first nozzle 51A is absorbed in the lead-in channel 55, and ink liquid droplets turned to be minute liquid droplets are ejected from the second nozzle. After the ink liquid droplets turned to be the minute liquid droplets are ejected from the second nozzle 51B, the ink absorbed in the lead-in channel 55 is returned via the first nozzle 51A into the pressure chamber 52. Ink recovery from the lead-in channel 55 to the pressure chamber is promptly carried out by performing liquid repelling processing to the lead-in channel 55. COPYRIGHT: (C)2009,JPO&INPIT
