AUTOMATIC PAPER FEED-SENSING APPARATUS FOR A PAPER SHREDDER, PAPER-FEEDING APPARATUS COMPRISING SAME, AND PAPER SHREDDER COMPRISING THE AUTOMATIC PAPER FEED-SENSING APPARATUS AND THE PAPER-FEEDING APPARATUS

摘要

The present invention relates to an automatic paper feed-sensing apparatus for a paper shredder, to a paper-feeding apparatus comprising same, and to a paper shredder comprising the automatic paper feed-sensing apparatus and the paper-feeding apparatus. The automatic paper feed-sensing apparatus of the present invention comprises: a sensor fixed at one end of a sensor bracket arranged at one side of a paper inlet of the paper shredder; and a rotating lever rotatably interposed between the paper inlet and the sensor to open and shut the front of the sensor. The paper-feeding apparatus of the present invention comprises: a paper feed unit, the top of which is covered by a cover, and which has a predetermined space for accommodating paper to be shredded; a paper inlet opening through the center of the bottom of the paper feed unit and in communication with a cutter unit arranged below the paper inlet; paper feed rollers which face each other at both sides of the paper inlet to feed paper in the paper feed unit to the paper inlet; and a press unit which moves vertically toward the paper inlet in accordance with the opening/shutting operation of the cover to press the center of the paper to be shredded such that the paper is folded in half, wherein the center of the bottom of said paper feed unit gradually becomes V-shaped to easily fold the center of the paper to be shredded. The paper shredder of the present invention comprises a cutter unit having a plurality of cutter blades arranged below the paper-feeding apparatus, and a shredding unit with a driving motor for driving the cutter unit.
