PURPOSE:To both increase rigidity of a sheet and prevent distortion of data on the sheet, by providing a conveying roller group which comprises rollers for forming a flat part and folded parts to the conveyed sheet. CONSTITUTION:A conveying roller group comprising rollers 1X, 1Y, which form a flat part 2A and folded parts 2B respectively in a central part and both edge parts of a sheet 2 while interposing and conveying the sheet 2, is provided. When the sheet 2 is conveyed at a prescribed speed, the flat part 2A and the folded parts 2B are formed by the rollers 1X, 1Y respectively in the central and both edge parts of the sheet 2, and rigidity in the direction of arrow heads A, B in the point end part of the sheet 2 carried in the direction of an arrow head C can be remarkably increased, while distortion of data of the sheet 2 can be prevented by the flat part 2A. |
