Abstract:
A sheet post-processing apparatus comprising:a post-processing tray for stacking the discharged sheets;a post-processing portion for performing post-processing for the stacked sheets,an output tray for receiving the sheets discharged after post-processing;a conveying means for conveying sheets from the lower part of the post-processing tray arranged upright and discharging the sheets after post-processing to the output tray; anda sheet guiding means disposed opposing the post-processing tray which presses particular portions of the sheet when the sheet is introduced into the post-processing tray so as to align the stacked sheets onto the post-processing tray, with the sheets being stacked substantially upright;wherein the sheet guiding means can rotate about an axle located near the upper part of the post-processing tray so that the lower part of the sheet guiding means rotationally moves toward the post-processing tray; and the sheet guiding means guides the sheet upward with respect to the post-processing tray when the sheet is introduced into the post-processing tray and presses the sheet against the post-processing tray face when the sheet is discharged to the post-processing tray.
