A sheet sorting device having a plurality of bin trays has a resilient member for imparting to a bin tray support member a force in the direction opposite to the direction of gravity and reducing a load applied to a bin tray drive source. A detecting device for stopping the driving of the drive source detects the movement of the drive source when the drive source moves up or down relative to the bin trays. Drive source has two lead portions, smooths the movement of the bin group and makes the amount of opening between the bins always constant.

Sheet sorting device

A sheet sorting device having a plurality of bin trays has a resilient member for imparting to a bin tray support member a force in the direction opposite to the direction of travity and reducing a load applied to bin tray driving means. Detecting means for stopping the driving of the driving means detects the movement of the driving means when the driving means moves up or down relative to the bin trays. Cam means has two lead portions, smoothes the movement of the bin group and makes the amount of opening between the bins always constant.

An automatic original conveying apparatus in which originals loaded on an original stacking unit are conveyed to a predetermined position one by one. Abnormal stacking of the original on the original stacking unit is detected, and continuation of operation is prohibited in response to the detection of such abnormal stacking of the originals.
