PROBLEM TO BE SOLVED: To improve the heat radiation effect at a heating part of a liquid droplet ejector. SOLUTION: The liquid droplet ejector 1 includes a waste liquid tank 71 which stores waste liquid of a liquid discharged from an ejection head unit 2 so as to recover the ejection function of the ejection head unit 2, a line 72 arranged to extend from the waste liquid tank 71 and return to the waste liquid tank 71 passing through the heating part of the ejection head unit 2, and a circulating means 18 which circulates the waste liquid of the waste liquid tank 71 to the pipe. Heat generated from the heating part of the ejection head unit 2 is radiated by the waste liquid which circulates through the line. COPYRIGHT: (C)2009,JPO&INPIT |
