ABSTRACT:
The present invention provides a sheet separating and conveying apparatus for separating stacked sheets and for conveying a separated sheet, comprises a sheet convey means for conveying the sheet, a friction means disposed in a confronting relation to the sheet convey means, a biasing means for urging the sheet convey means and the friction means against each other, a preliminary convey means adapted to be urged against the sheet convey means at an upstream side of a contact position between the sheet convey means and the friction means in a sheet conveying direction, and a friction releasing means for separating the sheet convey means and the friction means from each other, and wherein, when the sheet convey means and the friction means are separated from each other by the friction releasing means, the preliminary convey means is maintained in a condition that the preliminary convey means is urged against the sheet convey means.
