Mechanism for producing vacuum pressure and air flow for drawing recording paper of various widths to the platen surface of a printer enables such pressure and air flow to be held in a suitable range without adjusting the suction. A first suction area with the same width as the minimum width of the recording paper is disposed width-wise in the middle of the platen surface that opposes the inkjet head of the printer, and second suction areas are disposed on the left and right sides of the first suction area. The first suction area is divided into a grid by intersecting ribs to form first chambers, each having a first suction hole formed in a bottom thereof that communicates with a vacuum channel. The second suction areas are also segmented to form second chambers. Second suction holes are selectively formed in some, but not all, of the second chambers and are appropriately spaced from the first suction holes. The front edge of the first suction area is offset slightly from the front edge of the second suction areas. |
