<p>PROBLEM TO BE SOLVED: To provide a paper re-feeding device capable of preventing stretching noise caused by the limitation of deflection of paper resulting from the reverse rotation of a paper re-feeding roller. SOLUTION: This paper re-feeding device 52 comprises a reverse rotating means 11 and 12 for feeding out sheets from an image forming means 51 forming images on the sheets fed by a paper feeding means 50 by switching back the sheets one by one and a paper re-feeding roller part 4 re-feeding the paper to the image forming means 51 while holding the sheets from the reverse rotating means. A one-way clutch 9 is installed on the rotating shaft 19 of the paper re-feeding roller part 4. The rotation of the paper re-feeding roller part 4 in the direction reverse to a sheet re-feeding direction is prevented by the one-way clutch 9.</p> |
