Abstract
A sheet feeding device comprises a cassette for holding a stack of sheets, feeding means for longitudinally advancing the uppermost sheet of the stack from the cassette in pressing contact with the sheet at approximately the longitudinal medial axis of the sheet with respect to the feeding direction, separating pawl members for separating the uppermost sheet from the other sheets by engaging the uppermost sheet at its leading opposite corners to thereby temporarily restrain the uppermost sheet from advancing, and pressure members for pressing the uppermost sheet at its opposite side portions to a predetermined extent. The pressure members are retractable from the pressing position in accordance with the resilient force of the sheet when the advancing sheet is buckled by engagement with the separating pawl members.
