Abstract
A small-size-sheet stacking unit is attached on a printed sheet tray of a printing machine so as to receive printed sheets of small size, and is detached from the printing machine after such sheets are printed. The sheet stacking unit comprises a guide plate, a plurality of carriers for supporting side edges of a printed sheet and moving the printed sheet upward, a position sensor for detecting whether or not the printed sheet is at a position where the sheet is ready to be carried by the carriers, a driver for actuating the carriers, and a sheet receptacle for receiving the printed sheets.
