を特徴とするシート送り装置。[Claims for Utility Model Registration] A driving roller having an axial width corresponding to at least the maximum sheet width to be conveyed, and at least one small-width driven roller rolling in contact with the driving roller, and between these two rollers. In a sheet feeding device that pinches and feeds a sheet, a roller holding member that rotatably supports the driven roller is provided, and an arm portion that extends from a roller shaft fulcrum of the roller holding member toward an upstream side of sheet advancement, Due to the roller tangential force generated on the driven roller due to contact rolling with the drive roller at startup, the arm is moved so that the plane perpendicular to the rotation axis at the width center of the driven roller becomes parallel to the plane perpendicular to the rotation axis of the drive roller. A sheet feeding device characterized in that a portion near an end of the portion is swingably supported on a plane perpendicular to a rotation axis centered in the width direction of the driven roller and within a contact plane with a driving roller.
