摘要： A sheet feeding device includes a stacking unit configured to allow sheets to be stacked thereon; side end regulating members configured to make contact with both side ends of the stacked sheets so that positions of the side ends are regulated; a feeding unit configured to feed one sheet at a time from the stacked sheets; an air supply unit; and an air blow unit including a blow port from which air supplied from the air supply unit is blown against a side end of the stacked sheets, the air blow unit being housed in each of the side end regulating members. Each side end regulating member has an opening for exhausting the air that is blown from the blow port unit to the stacked sheets. An orientation of the blow port is adjustable about an axial line perpendicular to a plane corresponding to a surface of the stacked sheets.

摘要： In the present invention, when a status of clogging a paper due to some cause occurs, controls of inverting a conveyance roller and returning the jammed paper in a paper feeding tray is performed. At this time, the position of a paper damming up member is lowered by an actuator when the jammed paper is returned to the paper feeding tray and the conveyance roller is inverted so as to avoid a state in which the paper damming up member 33 hinders the returning of the paper and the paper cannot be returned to the paper feeding tray. The paper damming up member is lowered to a position that is lower than a conveyance guide plate at a downstream side in a paper conveying direction. Then, the paper is returned to the paper feeding tray without damage. The returned paper can be reused.
