Abstract

PURPOSE:To previously prevent a failure of ink jet operation and a drop of ink jet performance by collecting bubbles in the ink feed system effectively and by detecting a fixed quantity of collected bubbles and removing them. CONSTITUTION:Ink from the tank 38 passes through a small hole 54 of the bubble trap 53, ascends and advances to the filter 33. Mixed bubbles are flated and stored in the upper part of the trap 53. Also, the production and growth of bubbles from dissolved air in the ink are promoted and bubbles attached to the inside of trap are floated by the diaphragm 61 with multiple grooves and the electrostriction vibrator 62 beneath the diaphragm, which are attached to the inner bottom of the outer case 51. When a fixed quantity or more of bubbles is stored, the trap ascends, the detector 65 detects it. The stored bubbles are sucked up by the injector through the tube 36.
