PROBLEM TO BE SOLVED: To prevent the discharge failure of an ink from occurring by stabilizing the discharge operation of the ink, in an inkjet recording device. SOLUTION: In the inkjet recording device, an air bubble removing space 28 for accumulating an air bubble; air bubble removing passages 2a and 25b for establishing the communications of the air bubble removing space 28 with the outside; and a float 29 for guiding the air bubble trapped in a common liquid chamber 27 to the air bubble removing space 28, are provided in the common liquid chamber 27 inside an inkjet head 3 for discharging the ink from a nozzle 2 in the form of ink droplets. In addition, the air bubble is sucked from the air bubble removing space 28 by a suction part through the degassing passages 2a and 25b. Thus it is possible to stabilize the discharge operation of the ink and prevent the discharge failure of the ink from occurring. COPYRIGHT: (C)2005,JPO&NCIPI |
