Abstract
A sheet post-processing apparatus 100 includes bundle discharge rollers 6, a sheet detection sensor 31, a main tray 11, and a sheet hold device 32 having a plurality of hold portions 34a to 34c. When a sheet bundle is discharged from the bundle discharge rollers 6, the hold portions 34a to 34c rotate to a release position where the hold portions 34a to 34c stop holding the sheet bundle P stacked on the main tray 11, the main tray 11 moves downward to a wait position H2, and then, the hold portions 34a to 34c rotate to the lowest position, then the main tray 11 moves up to a hold position H1.
Claims7
A sheet post-processing apparatus, comprising:
- a discharge member for discharging a sheet;
- a discharge tray being movable up and down and for stacking sheets discharged from the discharge member successively thereon;
- a sheet detector for detecting that a sheet is discharged from the discharge member;
- and
- a sheet hold member being capable of changing its state between a hold state in which the sheet hold member holds the top surface of sheets discharged to the discharge tray and a release state in which the hold is released,
- wherein the discharge tray is capable of moving up and down between a hold position where the top surface of the sheets is held by the sheet hold member which is in the hold state and a wait position which is lower than the hold position and where the top surface of the sheets is not held by the sheet hold member which is in the hold state, and when the sheet detector detects sheet discharge, the sheet hold member changes its state from the release state to the hold state and the discharge tray moves down from the hold position to the wait position, then, the discharge tray moves up to the hold position, thereby the top surface of the sheets is held by the sheet hold member.
