Abstract
A sheet treating apparatus capable of stacking discharged sheets in the shape of bundle, including a sheet stacking device so positioned that the downstream side in the discharging direction is higher than the upstream side and serving to stack the sheets, a sheet receiving member so provided as to project from the sheet stacking device and serving to receive the upstream end of the sheets on the sheet stacking device, a sheet advancing device for advancing the sheet onto the sheet stacking device, an elastic annular sheet trailing end aligning member rotatably provided in the vicinity of the sheet advancing device and serving to move the sheets stacked on the sheet stacking device toward the sheet receiving member, and a pivotally movable regulating member provided in a vertically pivotable manner in the vicinity of the sheet advancing device and provided with an inclined face adapted to descend after the sheets are discharged onto the sheet stacking device and to guide, in the descended state, the trailing end of the sheet in the floating state toward the sheet stacking device, wherein the leading end of the inclined face in the descended state of the pivotally movable regulating member protrudes externally from the external periphery of the sheet trailing end aligning member while the lower end is positioned lower than the center of the sheet trailing end aligning member when it is in a truly circular state and the lower end is in the vicinity of the external periphery of the sheet trailing end aligning member.
