Sheet processing apparatus and image forming apparatus

摘要

A sheet processing apparatus (3) includes a pressing lever (46) turnable between a first position where the pressing lever (46) abuts with the sheet bundle on a stacking tray (34) and a second position where the pressing lever (46) is displaced on a side of a discharging part (44) side from the first position. The discharging part (44) has an upper roller (56) and a lower roller (57). The lower roller (57) abuts with a lowermost sheet of the sheet bundle and an upper roller (56) is configured to separate upward from the lower roller (57) during the shifting and to be displaced in a direction approaching the lower roller (57) during the discharging. The pressing lever (46) is configured to project upward from above an apex portion of the lower roller (57) at the second position and to turn into the second position during the shifting.

主权项

1. A sheet processing apparatus applying a post-processing on a conveyed sheet comprising:
a processing tray on which a plurality of sheet are loaded into a sheet bundle; a shifting unit configured to shift the sheet bundle in a width direction intersecting with a conveying direction of the sheet on the processing tray; a discharging part configured to discharge the sheet bundle from the processing tray; a stacking tray on which the sheet bundle discharged by the discharging part is stacked; and a pressing lever turnable between a first position where the pressing lever abuts with the sheet bundle on the stacking tray and a second position where the pressing lever is displaced on the discharging part side from the first position; wherein the discharging part includes a lower roller abutting with a lowermost sheet of the sheet bundle and an upper roller configured to separate upward from the lower roller during the shifting and to be displaced in a direction approaching the lower roller during the discharging of the sheet bundle; and the pressing lever is configured to project upward from above an apex portion of the lower roller at the second position and to turn into the second position during the shifting.
