    • 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.
    • 片材处理设备包括布置在片材输送路径上的第一输送辊对和第二输送辊对以及布置在第一输送辊对和第二输送辊对之间的冲压单元。 当检测到沿着从第一输送辊对朝向通过第一输送辊对的第二输送辊对的方向被输送的纸张的尾端时,其驱动第二输送辊对以相反的方向移动, 纸回落 此外,它使得止动件出现在由纸张的尾端的预定距离的向后移动限定的位置处,并且使得纸张抵靠止动器并且校正歪斜(如果有的话)。 在纠正偏斜之后,它通过冲压单元在纸张上切开一个孔。
