PURPOSE:To obtain a micro-miniature head and prevent choking of its head by abruptly gasifying liquid and letting the same spout from the nozzle. CONSTITUTION:An ink jet printer head part 97 communicates with an ink orifice part 98 and ink 102 is supplied to an ink pressure chamber 99 from a 101 through replenishing port 100. The liquid in the pressure chamber 103 where the liquid is filled is in contact with a heating element 104. Injection of the ink is accomplished by gasifying the liquid with the heating element 104 to increase the internal pressure, letting a pressure transmission plate 105 be deformed in the dotted line form 106 thereby pressing the pressure chamber 103 and letting ink particles 107 be injected. |
