けたことを特徴とする摩擦ローラ分離給紙装置。A feed roller that rotates in the paper feed direction based on the paper feed signal,
a separation roller supported via a means for partially transmitting torque to a shaft that pinches and presses against the paper path and constantly rotates in the opposite direction of paper feeding, and the shaft that supports the separation roller is A pressure lever is pivotally supported near one end of the pressure lever, which is swingable around a pressure drive shaft having a pressure gear that meshes with a gear provided on the feed roller. The above-mentioned separation roller is used in a friction roller separation paper feeding device that is always biased in the direction of pressure contact and separates double feeding by utilizing the difference between the frictional force between the roller and the paper and the frictional force between the paper sheets. is in pressure contact with the feed roller with a predetermined pressure that can prevent double feed separation and bottom feed, and the pressure lever contacts and rotates in the direction to further increase the pressure. A friction roller separation paper feeding device characterized by being provided with a stopper for regulating the friction roller separation.
