PROBLEM TO BE SOLVED: To easily regulate transferring and agitating performances of ink without adhering the ink to a rotary shaft of an ink transfer conveyor of an ink supplying unit by a simple method. SOLUTION: A rotary shaft 1 of an ink transfer conveyor adopts a square pipe. A T-shaped blade body 8 is mounted at a predetermined angle 6 to an axial center via a predetermined interval in an axial direction on a flat surface of an outer periphery by welding. The body 8 is assembled symmetrically at a lateral side at an oblique angle θ and at 90 degrees of an interval of a pitch in a circumferential direction and at a mounting pitch S of an axial direction with a lengthwise center of the shaft 1 as a reference with a supply port of an ink pump corresponding to a center of the shaft. |
