PROBLEM TO BE SOLVED: To surely guide the motion of an ink tube to feed an ink to an ink jet head, which follows the motion of the ink jet head, in a manner not to go out of control. SOLUTION: One side of an ink tube 8 is engaged with one of cursor running paths and the other side is bent into a U-shape and connected to a cursor 4 which reciprocates along a Y rail 2, and the ink tube 8 follows the movement when the cursor 4 reciprocates along the Y rail 2. A steel belt 20 of which the cross section is curved is superposed with the ink tube 8, and one side of the steel belt 20 is engaged with one side of the cursor running path, and the other side is connected to the cursor 4. Between the steel belt 20 and the ink tube 8, a tube guide 14 comprising a band-shape elastic body of approx. the same length with them is arranged, and the tube guide 14 and the steel belt 20 are connected with fixing utensils 18 relatively movably with each other in the longitudinal direction, and the tube guide 14 and the ink tube 8 are connected with fixing utensils 16 relatively movably with each other in the longitudinal direction. |
