PROBLEM TO BE SOLVED: To contribute to reduction in device cost while suppressing decrease in sheet discharge efficiency. SOLUTION: A multi tray part 30 includes a sheet discharge path 310 for conveying a sheet P2 to be discharged, a plurality of sheet discharge trays 32 disposed along the sheet discharge path 310, a plurality of switching guides 40 provided in the sheet discharge path 310 corresponding to the respective sheet discharge trays 32, and having guide fins 42 capable of changing its attitude between a retracting attitude S1 for letting the sheet P2 go during conveyance and a distributing attitude S2 for distributing the conveyed sheet P2 to the sheet discharge tray 32, and an attitude changing means 50 for changing the attitude of the guide fins 42. The attitude changing means 50 is composed to set the attitude of a guide fin 42 corresponding to a sheet discharge tray 32 which is not chosen by driving of one driving motor 71 in the retracting attitude S1 before changing the attitude of a guide fin 42 corresponding to one chosen sheet discharge tray 32 from the retracting attitude S1 to the distributing attitude S2.
