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.

Method and device for correcting attitude of transferred sheet

A paper sheet handling apparatus including a plurality of sheet accumulating portions and a sheet conveyor. A pointed separator is mounted on the conveyor for movement into a stack of paper sheets accumulated in one sheet accumulating portion to divide the stack into two parts with a gap formed therebetween. Gripping fingers mounted on the conveyor are moved into gripping engagement with one of the divided parts of the stack and then retracted to transfer the gripped part of the stack onto the conveyor. Holding members on the conveyor are movable into the gap to hold the paper sheets of the other part of the stack. The conveyor is movable to convey the gripped paper sheets to another sheet accumulating portion. The gripping fingers are again moved to transfer the thus conveyed sheets to the other sheet accumulating portion. Sensors are mounted on the conveyor to determine whether or not the paper sheets to be transferred are directly positioned relative to the sheet transferring members of the sheet accumulating portions and, if not correctly positioned, corrective action is effected in response to the determined incorrect positioning.
