Title: Sheet processing apparatus with open/close switchable sheet discharging member

Abstract: A sheet processing apparatus includes a sheet conveying path for receiving a sheet conveyed from the outside and conveying the sheet therethrough to be discharged, a stack tray for stacking a plurality of the conveyed sheets for stapling, a stapler for stapling the plurality of the sheets stacked on the stack tray, and an output tray for receiving the discharged sheets. The sheet conveying path includes a first conveying path for guiding the conveyed sheet to the stack tray for stapling, and a second conveying path for guiding the conveyed sheet to the output tray bypassing the stack tray. The sheet processing apparatus further includes a discharging member for discharging the conveyed sheet or the sheets guided by the first conveying path or second conveying path, a discharging member switching device which selectively switches the discharging member to a closed condition for discharging the sheet or sheets by sandwiching them or to an open condition for discharging the sheet or sheets without sandwiching them, and a controller configured to control the discharging member switching device to switch the discharging member to the open condition before a tip end of the sheet being conveyed through the first conveying path reaches the discharging member.
