摘要： A sheet post-processing apparatus discharges and conveys a sheet from a process tray to a storage tray, and decelerates a bundle hook and a paper discharge roller when the bundle hook reaches a discharge start position of a bundle of sheets. At this time, a tangential speed of the paper discharge roller is faster than a movement speed of the bundle hook. Subsequently, the sheet post-processing apparatus stops the paper discharge roller in accordance with a rotation position of the bundle hook, and then decelerates the movement speed of the bundle hook. After the sheets are stacked on the storage tray, the bundle hook accelerates to return to a home position. Additionally, the sheet post-processing apparatus includes a spool 17 having a sheet pressing guide member 16 with a bent portion 16A. When the sheets are conveyed to a process tray 13, the spool 17 is rotated forward to longitudinally align the sheets and then is backwardly rotated to press the sheets using elastic force of the sheet pressing guide member 16, thereby preventing a gap from occurring between the sheets or preventing the sheets from being misaligned.
摘要翻译：纸张后处理装置将纸张从处理托盘排出并传送到存储托盘，并且当捆钩到达一束纸张的排出开始位置时，使捆钩和排纸辊减速。此时，排纸辊的切线速度比束钩的移动速度快。随后，纸张后处理装置根据捆钩的旋转位置停止排纸辊，然后使捆钩的移动速度减速。在将纸张堆叠在存储托盘上之后，捆钩加速以返回到原始位置。此外，片材后处理装置包括具有弯曲部16A的片材按压引导构件16的卷轴17。当纸张被输送到处理托盘13时，卷轴17向前旋转以纵向对准纸张，然后向后旋转以使用片材挤压引导部件16的弹力来挤压纸张，从而防止在纸张或防止纸张不对准。
