<p>The vacuum pressure and air flow for pulling recording paper of various widths to the platen surface can be held in a suitable range without adjusting the suction. A first suction area 51 with the same width as the minimum width L of the recording paper 12a is disposed in the middle of the width of the platen surface 25a that opposes the inkjet head 22 of the printer 1, and second suction areas 52 and 53 are disposed on the left and right sides of the first suction area 51. The first suction area 51 is divided into a grid by longitudinal ribs 41 and 42 and lateral ribs 43, and the bottom parts of the grid chambers 44 render a first suction hole 45 that communicates with the vacuum channel through which air is pulled by a vacuum fan 26a. The second suction areas 52 and 53 are segmented by longitudinal ribs 46 and 47 and lateral ribs 48 and 49, and second suction holes 54 and 55 are formed in chambers separated from the first suction area 51. The front edge H1 of the first suction area 51 is removed slightly to the upstream side in the recording paper transportation direction B from the front edge H2 of the second suction areas 52 and 53.</p> |
