PROBLEM TO BE SOLVED: To realize a liquid droplet delivering apparatus which can obtain stable delivering performance without causing ink feeding insufficiency, clogging, etc. to any nozzle even when the nozzles different in nozzle diameter are equipped. SOLUTION: A plurality of nozzle groups which deliver a liquid, and an intake 31 for the liquid for each nozzle group are equipped in a cavity unit 10. A plurality of filter hole parts 51 are integrally continuously formed in connection in a filter body 50 attached to cover a plurality of the intakes 31. Many apertures 53 are formed penetrating in the filter hole part 51 correspondingly to an opening region of each intake 31. At least a part of the plurality of nozzle groups is different in nozzle diameter from the other nozzle groups. When the nozzle diameter of the nozzle group corresponding to each filter hole part 51 is large, an aperture diameter of the filter hole part 51 of the filter 50 is set large. When the nozzle diameter is smaller than the large nozzle diameter, the aperture diameter is set smaller than the large aperture diameter. COPYRIGHT: (C)2007,JPO&INPIT |
