PROBLEM TO BE SOLVED: To keep suction pressure and a flow rate for sucking various widths of recording paper sheets onto a platen face, within respective proper ranges thereof, without regulating suction. SOLUTION: The first suction area 51 with the same width same to the minimum paper sheet width L of the recording paper sheet 12a is provided in the width-directional central part of the platen face 25a opposed to an inkjet head 22 of a rolled paper sheet printer 1, and the second suction areas 52, 53 are provided in both right and left sides of the first suction area 51. The first suction area 51 is partitioned grid-likely by longitudinal ribs 41 and 42 and lateral ribs 43, and a bottom portion of each grid-like partitioned chamber 44 is made to serve as the first suction hole 45 communicated with a suction passage sucked by a suction fan 26a. The second suction areas 52, 53 are partitioned by longitudinal ribs 46, 47 and lateral ribs 48, 49, and the second suction holes 54, 55 are formed in a section separated from the first suction area 51. A front end position H1 of the first suction area 51 is retracted by one stage to an upstream along a recording paper sheet conveying direction B from a front edge position H2 of the second suction areas 52, 53.
