。A vacuum suction means 10 is installed in Job' and is oriented in the vertical direction. In the case of single-sided copying, this vacuum suction means 1o
The lower suction surface 10b sucks in the air and removes the paper tray 1.
The sheets 2 stacked on top are adsorbed to the bottom surface of the endless belt 9 of the conveying means 3, and the sheets 2 adsorbed by the endless belt 90 rotations.
It performs the normal operation of sending out the material to the conveyor belt 5 side. In the case of double-sided copying, the paper 2 in the paper tray 1 is first fed out by the above operation, and a copy is made on one side of the paper 20. The paper 2 on which one side has been copied is discharged by a carry-out roll 11 into a double-sided copying tray 12 provided above the conveyance means 3.

複写が行なわれるようになる。Thereafter, upon input of the double-sided copying signal, the vacuum suction means 10 sucks air from the upper suction surface 10α, and at the same time, a reversing clutch (not shown) is connected, and the endless belt 9 is rotated in the opposite direction to that when feeding the paper. ing. In addition, an air nozzle 13 is provided below the carry-out roll 11 to deflect the leading edge of the paper 2 downward.
The paper 2 in the paper 2 is sent out by the conveying means 3, and the remaining sides are copied.
