Abstract: PURPOSE:To ensure that paper is fed sheet by sheet by sucking a sheet of paper at the bottom with the vacuum suction of a drum, feeding the paper to a paper feed path while being kept in a flexible state, and delivering surplus sheets of paper to a surplus paper recovery path after separation of the surplus sheets, when sheets of paper are pulled out together. CONSTITUTION:Paper 15a is pulled out to a paper feed path 14a by friction with a feed roller 12 which rotates forward in an arrow B direction by a hopper 11, and the paper 15a is arranged in the paper feed path 14a. Then the paper is vacuum-sucked onto the peripheral surface with vacuum suction perforations of a paper suction drum 21 which rotates in a paper feed direction shown by an arrow A. Next, the paper is sent to a continuous paper feed path 14b in a flexible state, and surplus sheets of paper 15b which are puled out by the feed roller 12 together with the paper 15a are not vacuum-sucked onto the peripheral surface of the paper suction drum 21.
