PROBLEM TO BE SOLVED: To obtain an ink jet reorder in which bubbles are prevented from flowing into an ink jet head by separating bubbles contained in ink efficiently and assembling work is facilitated by simplifying the structure for separating bubbles. SOLUTION: Since a supply opening 24b is opening into ink on the inside of a third wall 29, ink is supplied from a large capacity tank into a buffer tank 20 without entraining air. After ascending along the third wall 29 and a first wall 27, the ink descends between the first wall 27 and a second wall 28, and then it is stored in a chamber between the second wall 28 and an exhaust opening 24 before being supplied from the exhaust opening 24 to an ink jet head. When the ink changes the direction in order to ascend and descend, bubbles are separated efficiently and stored along the ceiling part of the chamber on the upstream side of the second wall 28. |
