PURPOSE:To enable a sheet, even generating a curl or the like, also to be well aligned, by providing a rotary paddle, which gives the sheet retractive force in the crossing direction of two planes crossing at a right angle, and an auxiliary rotary paddle, which transfers the sheet to the direction of one of the planes with retractive force weaker than that of the former paddle. CONSTITUTION:A paddle 61, retracting a sheet of paper toward the direction of guides 3 and 4, while a paddle 62, retracting the sheet toward the direction of the guide 4, enable the sheet 5 to be surely positioned and aligned by the guides 3 and 4. The retaining action of a curl by pressing force of the paddle 62 is provided particularly for the sheet even if it is curled, positioning a side of the sheet 5 surely to the guide 4. While another side of the sheet 5 in its lateral direction is positioned to the guide 3 by the action of the paddle 61. Further an angle formed by the retractive direction of the paddle and the advancing direction of the sheet is preferable such that the paddle 61 is tilted at 45 deg. while the paddle 62 is placed at 0 deg. with respect to the advancing direction of the sheet, here retractive force in the lateral direction is too strong if the paddles are both titled at 45 deg. while too weak if the paddle 61 is titled at 30 deg. and the paddle 62 is placed at 0 deg.. |
