Abstract:
1. A sheet storing apparatus, comprising: a sheet bundle placement device on which bundle-shaped sheets are placed; a stack tray which is arranged at a downstream side of a discharging port of the sheet bundle placement device; a tray lifting-lowering device which lifts and lowers a sheet placement face of the stack tray in a stacking direction; and a control device which controls the tray lifting-lowering device, wherein the stack tray includes a sheet placement tray which forms a lifting and lowering sheet placement face, a sheet tailing end regulating face which regulates a position of a tailing end of a sheet stacked on the sheet placement face, and a tailing end supporting member which temporarily supports a sheet bundle dropping onto the sheet placement face through the discharging port, the tailing end supporting member includes a sheet supporting face which is capable of being moved between an operating position located above the sheet placement face of the sheet placement tray and a retracting position retracting from a side above the sheet placement face, the sheet supporting face is arranged at a middle position in a sheet drop direction between the discharging port and a face of an upmost sheet on the sheet placement face, a first height difference between the discharging port and the sheet supporting face is set to be larger than a maximum allowable sheet bundle thickness, and a second height difference between the sheet supporting face and the upmost sheet on the sheet placement face is set to be smaller than the first height difference.
