Original Abstract Submitted

A sheet feeding apparatus includes: a conveying roller; a separating roller which forms a nip portion by pressing the conveying roller and separates a sheet conveyed by the conveying roller one by one in the nip portion; a moving portion configured to move a stacking portion from a first position at which a sheet stacked in the stacking portion and a feeding roller are separated from each other to a second position at which the sheet stacked in the stacking portion abuts on the feeding roller; and a cover member which is movable between a third position to cover a rotation shaft of the separating roller and a fourth position to expose the rotation shaft of the separating roller, in which the cover member placed in the fourth position moves to the third position along with movement of the stacking portion from the first position to the second position.
