Abstract
A sheet post-processing device of the present invention conducts post processing on sheets and then ejects the sheets on an offset tray. Upon the ejection, the sheets are sorted by a sorting drive section reciprocating the offset tray horizontally. The sheets are aligned at the trailing edges thereof by a plurality of sheet edge stopper columns erected freely rotatable. The offset tray is moved vertically along the sheet edge stopper columns by, for example, a lifting and lowering motor. Friction rollers are provided as linking means for rotating the sheet edge stopper columns in accordance with a horizontal movement of the offset tray. As to the horizontal movement and a vertical movement of the offset tray, the friction rollers transmit a driving force to the sheet edge stopper columns only when the offset tray is moved horizontally. Consequently, the stack disturbance of the sheets can be prevented both when the offset tray is moved horizontally and when the offset tray is moved vertically.
