ABSTRACT:
An auto sheet feed device for an office automation system uses: a paper loading plate which moves upwardly and downwardly according to the quantity of paper loaded thereon; a loading pick up device for picking up paper loaded on an upper part of the paper loading plate according to a control signal; a pressurizer for maintaining the paper loading plate and the pick up device in close adherence to each other; a resistance plate for separating the paper picked up by the pick up device from the paper loading plate; and a resistance plate varying device for maintaining an entry angle between the resistance plate and the paper as paper is picked up by the pick up device. Preferably, the resistance plate varying device includes a rack gear formed on the paper loading plate, an idle gear contacting the rack gear and driver thereby, and a fan shaped gear rotated by movement of the idle gear to adjust the angle between the resistance plate and paper in the paper loading plate.
