The automatic paper supply apparatus includes a paper loading stand for loading paper sheets to be shredded, the paper sheets being loaded while facing the shredding part; a supporting jaw installed at a front end of the paper loading stand so as to keep and support the paper sheets to be shredded; a lifting board included in the paper loading stand in such a manner that the lifting board can be rotated toward an upper direction; a feed sensor which is positioned at a lower part of the lifting board so as to sense if paper sheets to be shredded are supplied; a feed roller positioned at an upper part of the lifting board, the feed roller being driven when the feed sensor senses paper sheets so as to carry the paper sheets to be shredded to the shredding part; a pressing spring which elastically supports the lifting board and allows the paper sheets to be shredded, which has been put on the paper loading stand, to face the feed roller of an upper part of the paper shredder; and a catching board which is positioned above an upper part of the paper loading stand while being spaced from the paper loading stand, and allows a sheet of paper at an upper layer of stapled paper sheets to be released from the stapled part of the paper sheets. The present invention can shred stapled paper sheets without need to previously remove the staple thereof, increases the user's safety, and prevents damage to the apparatus.</p> |
