A sheet storing apparatus for stacking sheets discharged from a printer and storing the sheets therein, the apparatus having a plurality of trays, separate driving systems of the trays, and a detector for detecting failure in sheet storing operation on each of the trays. When the detector detects failure in sheet storing operation on one of the trays, successive sheets are transported to another tray. Further, each of the trays has a mechanism for moving the tray horizontally and a mechanism for moving the tray vertically, and the movements of the trays are independent. When it is detected that one of the trays has trouble in its horizontal movement mechanism and/or vertical movement mechanism, sheets are received on the other trays.
