Abstract
A sheet processing apparatus has a tray supported in a vertically movable manner and adapted to support sheets discharged from the main body of the sheet processing apparatus, and an elevate/lower unit for elevating or lowering the tray and having a detector for outputting a detection signal by detecting an uppermost one from among the sheets discharged in succession and stacked on the tray and a controller for controlling the elevate/lower unit so as to lower the tray in response to the detection signal inputted from the detector. The controller, after the input of the detection signal from the detector, if the input of the detection signal is not terminated even after lowering of the tray by a predetermined amount, executes a serial control of lowering the tray until the input of the detection signal is terminated, then elevating the tray until the detection signal is inputted, and lowering the tray until the detection signal is terminated.
