Abstract

A sheet post-processing apparatus having a sheet tray, a sheet transportation path for guiding a sheet into the sheet tray, a bypass path bypassing a part of the sheet transportation path for guiding a sheet into the sheet tray, a post-processing mechanism for performing a post-processing operation on one set of sheets retained in the sheet tray, and a sheet transportation mechanism for feeding the sheet into the sheet tray. During the post-processing operation performed on the one set of sheets previously fed into the sheet tray, the first sheet of the next sheet set is once stopped in one of the transportation path and the bypass path, and the second sheet of the next sheet set is introduced into the other of the bypass path and the transportation path. Upon completion of the post-processing operation performed on the one sheet set, the first and second sheets of the next sheet set are fed into the sheet tray.
