  • Publication number: 20080211166
    Abstract: An exemplary embodiment of the invention provides a sheet feeding device in which the vibration and noise can largely be reduced in a rotating shaft of a pressing roller while multi feed is sufficiently prevented. A top-most sheet P stacked on a sheet stacking member is drawn by a feed roller and separated one by one between the feed roller and the separating member, and the sheet is fed toward a first sheet guide member. A pair of conveying rollers conveys the sheet while nipping the sheet, and the conveying rollers draws the sheet from a nip between the pressing roller and the separating member. A projection of a second sheet guide member is projected toward a position below a tangent line, so that a force with which the sheet pushes up the pressing roller is eliminated to suppress generation of vibration and noise in the pressing roller.
