Zusammenfassung: | The invention relates to a sheet stacking apparatus, including: a movable stack portion on which sheets are to be stacked; a detection portion configured to detect whether or not a topmost sheet of sheets stacked on the stack portion is positioned at a predetermined position; and a control portion configured to position the topmost sheet at the predetermined position based on a detection result of the detection portion, wherein in a case where the control portion moves the stack portion at a first speed so that a topmost sheet on the stack portion deviates from the predetermined position, the control portion moves the stack portion at a second speed lower than the first speed to position the topmost sheet at the predetermined position. The invention also relates to an image forming device.
本发明涉及种片材堆叠装置,包括:片材将堆叠于其上的可移动的堆叠器件(33);检测器件(100、200),其用于检测堆叠在堆叠器件(33)上的片材中的最顶部片材是否定位在预定位置处;和控制器件(50B),其用于根据检测器件(100、200)的检测结果而将所述最顶部片材定位在预定位置处,其中,在控制器件(50B)以第速度移动堆叠器件(33)以使得堆叠器件(33)上的最顶部片材偏离预定位置的情况下,控制器件(50B)以小于第速度的第二速度移动堆叠器 |
