徴とする給紙装置。 A friction feed roller that rotates while being in pressure contact with the paper placed on the paper feed table; a friction separation roller that rotates while being in pressure contact with the leading edge of the paper to separate and feed the paper one by one; a separation member that presses the paper against the friction separation roller; a delivery roller that is provided at a position separated from the friction separation roller by a predetermined distance and sends out the paper along a conveyance path; and a connection between the delivery roller and the separation member. A sensor is provided in between to detect the presence or absence of paper, which is provided close to the separation member, and when the sensor detects paper at the start of paper feeding, the friction feed roller and the friction separation roller are operated until the sensor no longer detects the paper. A paper feeding device comprising a reversing drive means for reversing the paper.
