PURPOSE:To prevent any skew of a paper form by installing the third roller in free advance and retreat in relation to the first roller and attaching the third roller on the first roller after the rear edge of the paper form held on a holding member intrudes between the first and third rollers. CONSTITUTION:Paper forms transported while being guided by the first guide member 402 are sucked by the first and second rollers 10 and 11 and held by a holding member 14. In this case, the third roller 2 is positioned in its retreat position. The rear edge of a sucked paper form is scraped up by a blade roller member 10c, and shifted from between the rollers 10 and 11 to a space between the rollers 10 and 2. Then, the roller 2 is positioned in its operation position, and the rear edge of the paper form is bitten into a gas between the rollers 10 and 2. Accordingly, the biting of paper form is made uniform, and the generation of skew on the paper form is prevented, and the paper form is discharged into the second guide member 403, and then the roller 2 is returned to its retreat position. |
