PROBLEM TO BE SOLVED: To suppress deterioration of record quality while giving anti-bending strength to a record medium in a configuration including plural liquid jet heads.SOLUTION: Six heads 10 are arrayed in zigzag in a primary scanning direction. Jet surfaces 10a of the heads 10 are arranged in two columns 10aR1, 10aR2 along the primary scanning direction. A waveform provision part 50 is disposed between the columns 10aR1, 10aR2. The waveform provision part 50 is configured so as to provide a sheet P with at least a waveform along the primary scanning direction on the upstream side of a transport direction of the column 10aR2 and includes a roller pair 51, 52. Contact points 51x, 52x of the roller pair 51, 52 with the sheet are arranged at mutually different positions in relation to the primary scanning direction, transport direction and vertical direction. |
