PURPOSE:To arrange the end of paper and one side of side edges at the specified position and thereby stack sheets of paper, by conveying these sheets of paper to be discharged one by one to a duplex tray of a duplex copying machine, toward a front stop plate and a basic wall by means of a tilting roller. CONSTITUTION:A stacking device of a duplex tray for a duplex copying machine is provided with a front stop plate 9 serving as a reference surface in order to arrange the end of paper 1, a basic side wall 10 to arrange a side edge with a side edge at the reference side of the paper, and a tilting roller 11 to convey the paper discharged inside the duplex tray 5 toward the front stop plate 9 and the basic side wall 10 one by one. The tilting roller consisting of sponge rubber is installed in and around a corner angle of the duplex tray 5 at the side where the basic side wall 10 is installed in a way of being tilted toward the basic side wall 10 with a forward direction of the paper. The paper 1 that finished its fixation for one-side copying is turned over via a conveyor belt 2 and a turn roller 3, and is discharged to the inside of the duplex tray 5 from a discharging roller 4 one by one, thus the paper 1 follows the front stop plate 9 and the side wall 10 and arranged in order after its topmost paper alone is conveyed with dead load of the tilting roller 11. |
