Abstract
A method for correcting a direction of a side of a transferred sheet in which according to a first step the sheet is driven forward at a driven portion thereof other than a forward end thereof when a pair of feed rollers contacting with each other to form a contacting line therebetween is rotationally stopped, until the forward end of the sheet contacts with the pair of feed rollers near to the contacting line and a curvature of the sheet is formed between the forward end and the driven portion with a clearance over a guide for the sheet so that a rigidity of the sheet against the curvature thereof generates a pressing force between the forward end of the sheet and the pair of feed rollers. In accordance with a second step in which thereof, after the first step, the pair of feed rollers is rotated in the backward direction so that the forward end of the sheet is urged backward and the curvature of the sheet is maintained with the clearance over the guide for the sheet, and a third step in which after the second step, the pair of feed rollers is rotated in the forward directing so that the sheet is fed forward.
