Abstract: The overlapping regions L are formed by overlapping the outer cylinder vent holes and the inner cylinder vent holes. If the suction port of the inner cylinder receives a suction force from the blower, air is sucked toward the suction port from the suction chamber facing the overlapping region L of the inner cylinder vent hole and the outer cylinder vent hole, out of the plurality of suction chambers, via the overlapping region L. The outer cylinder and the inner cylinder are so configured that the overlapping region L becomes narrower in the rotation direction Dr from the center toward the both ends in the axial direction Da.

Abstract: The present invention is a position adjustment method for head units arrayed in a predetermined width direction attachably to and detachably from a base member. A position of a second head unit in the width direction and a rotation direction are respectively adjusted while the second head unit is engaging a tip part of a reference pin. More particularly, a width direction adjuster moves the second head unit in the width direction with a first head unit kept fixed to the base member. In this way, the gap between the first head unit and the second head unit is adjusted. Further, a rotation direction adjuster moves the second head unit in the orthogonal direction at a separation position distant from the reference pin. In this way, a rotation direction position of the second head unit with respect to the tip part of the reference pin is adjusted.

Abstract: An image is printed on the front surface M1 by discharging the inks to the front surface M from the discharge heads 321 (first head) facing the front surface M1 (recording surface) of the printing medium M from above. Thus, the inks discharged from the discharge heads 321 partially become mist to possibly produce ink mist. Accordingly, the ink cover 51 (first cover) is arranged between the discharge heads 321 and the front surface M1 of the printing medium M before the discharge heads 321 discharges the inks to the printing medium M. By providing the ink cover 51 for the front surface M1 of the printing medium M before printing in this way, the adhesion of the ink mist to this front surface M1 can be suppressed.

Abstract: The printing medium M after color printing is performed on the front surface M1 (recording surface) by the color printing unit 32 can be conveyed while the front surface M1 and the back surface M2 of the printing medium M are inverted twice by the only rollers 471 to 478 (rotary bodies) in contact with the back surface M2 (non-recording surface) of the printing medium M (inverting conveying part 47). In this way, without providing air turn bars, a time to convey the printing medium M from the color printing unit 32 to the white printing unit 33 can be secured while the printing medium M is firmly supported by the rollers 471 to 478 in contact with the back surface M2 of the printing medium M.

Abstract: An inkjet printing apparatus is selectively composed of a plurality of transportation units, i.e., an inlet unit, a first intermediate unit, a second intermediate unit, and an outlet unit, having a transport path with slopes in side view of a transportation direction from a paper feeder to a take-up roller. When the transportation units are connected, a connecting part of the transportation unit is an inclination change point VP of the transport path. This achieves maintained tension to the print medium. As above, the inkjet printing apparatus may be selectively composed of a plurality of transportation units. Accordingly, the inkjet printing apparatus is constructible by combination of the units for various type productions, leading to a suppressed stock.
