Document Type and Number:
Japanese Patent JP4358808
Kind Code:
B2
Abstract:
A sheet processing apparatus comprises a first conveyer roller pair and a second conveyer roller pair arranged on a sheet conveyance route along with a punch unit arranged between the first conveyer roller pair and the second conveyer roller pair. When it detects the tail end of a sheet of paper being conveyed in the direction from the first conveyer roller pair toward the second conveyer roller pair passing the first conveyer roller pair, it drives the second conveyer roller pair to rotate reversely and move the sheet of paper backward. Additionally, it causes a stopper to appear at a position defined by a predetermined distance of backward movement of the tail end of the sheet of paper and so as to make the sheet of paper abut the stopper and correct the skew, if any. After correcting the skew, it cuts a hole in the sheet of paper by means of the punch unit.
