Abstract: A sheet stacking apparatus which is capable of efficiently stacking sheets of various sizes while efficiently using space therein to thereby realize compactness thereof, and maintaining a high availability. Stacker trays for stacking sheets discharged from an image forming apparatus can be separately removed. It is detected whether any of the stacker trays is removed. When large-size sheets are stacked, a stacker control section causes the stacker trays to operate as one tray to stack the sheets in a state extending on the stacker trays, whereas when small-size sheets are stacked, the section causes one of the stacker trays to stack the sheets. Further, when one stacker tray is removed to make it impossible to stack the large-size sheets, the section causes a display section to display a guide message advising setting of the removed stacker tray.

Abstract: A sheet processing apparatus capable of reliably superposing a sheet to be buffered and a following sheet in a manner displaced by an allowable displacement amount, thereby making it possible to suppress generation of misalignment. A sheet discharged from an image forming apparatus is temporarily held back, and a following sheet is superposed on the held-back sheet in a state displaced in a conveying direction. A length in the conveying direction of the sheet to be held back and a length in the conveying direction of a sheet bundle of the superposed sheets are measured. A displacement amount provided between the superposed sheets, computed as a difference between the measured length of the sheet and the measured length of the sheet bundle, is adjusted such that the displacement amount becomes a target displacement amount.

In accordance with results of detection by lateral registration detection sensors performed when a sheet reaches a lateral registration detection sensor unit, the sensor unit is moved in a width direction for sheet end detection. Based on a moving distance of the sensor unit from a standby position to a position where the sheet end is detected, a shift amount to be shifted the sheet in the width direction, i.e., a lateral registration error, is computed.
