A sheet post-processing device is provided which includes a post-processing tray on which sheets of paper supplied from an image forming device are stacked, and a post-processing section for applying a post-processing operation to edges of one side of the sheets of paper stacked on the post-processing tray. The device further includes a first feed-out opening for discharging, to outside, the sheets of paper having been subject to the post-processing operation, a first discharge transport path for transporting the sheets of paper from the post-processing tray to the first feed-out opening, and a feed-out section for discharging the post-processed sheets of paper from the post-processing tray to the first discharge transport path.

Sheet post processing device with feed out

A sheet post-processing device comprises a feed-in opening through which sheets of paper fed out of a copying machine are supplied, a staple tray on which the sheets of paper to be stapled are stacked, a stapler for stapling the sheets of paper stacked on the staple tray, a feed-out opening for discharging the stapled sheets of paper, and a plurality of paths for transporting the sheets of paper from the feed-in opening, to the staple tray, and further to the feed-out opening. The sheet post-processing device is further characterized in that the feed-in opening is positioned not higher than a position of an upper edge of the post-processing tray and not lower than a position of a lower edge of the post-processing tray. With this arrangement, the sheet post-processing device can be arranged so as to have smaller limitation on positions of the post-processing tray and the feed-in opening in the sheet post-processing device.
