ABSTRACT:
A paper shredder paper feed mechanism, characterized in having a paper insert opening structured from two movable paper feed tubes, which are configured above paper shredding cutters. Two ends of each of the paper feed tubes are respectively positioned in W-shaped embed grooves of positioning plates of a frame. The two paper feed tubes are ordinarily closed together, thereby enhancing safety and preventing dust and miscellaneous objects from falling into the paper shredder. When paper is inserted into the paper insert opening, the thickness of the paper opens the two paper feed tubes, thereby guiding the paper smoothly guided into the paper shredding cutters.
