Abstract
An auxiliary support plate is connected, by a leaf spring, to a middle portion of a lower end of a sheet holder, in a sheet width direction, so that a lower end part of the auxiliary support plate rotates and retracts below an upper surface of the sheet holder. A sheet feed roller, facing an upper surface of the auxiliary support plate, is rotatably supported by an arm, which can rotate about a drive shaft disposed upstream in a sheet advance direction.
