PURPOSE:To feed sheets of copying paper of a both-side copying machine, sheet by sheet, securely by providing the 1st copying paper conveyance path, the 2nd copying paper conveyance path, and an intermediate stock part and equipping the intermediate stock part with an intermediate tray, a movement stopping means, a matching means, a feeding means which is placed in the 1st operation state wherein copying paper is pressed relatively gently or in the 2nd operation state wherein copying paper is pressed relatively strongly, and an operating mechanism. CONSTITUTION:When plural sheets of copying paper are stacked on the intermediate tray 48, a feed roller 58 is pressed against the uppermost copying paper in the stack state and feeds the uppermost copying paper toward a preventing mechanism 86 for prevention against copying paper multiple feeding. When the copying paper on the intermediate tray 48 becomes less as the copying paper is fed, the 1st rocking member 68 is swiveled through the operation of a spring member in the 2nd operation state. Therefore, the feed roller 58 is pressed against the top surface of the uppermost copying paper with relatively large necessary pressure at any time without reference to the quantity of sheets of copying paper on the intermediate tray 48, and consequently copying paper is fed securely as necessary. |
