Abstract:
1. A paper shredder, comprising a paper support part comprising a first paper support part having a first length, a second paper support part having a second length greater than the first length, and a paper feed slot between the first paper support part and the second paper support part; a first roller in which a portion thereof is exposed upward from the second paper support part through an opening defined in the second paper support part; a second roller in which a portion thereof is exposed upward from the first paper support part through an opening defined in the first paper support part; a cutter disposed below the paper feed slot to shred an introduced paper; and a motor operating the first roller, the second roller, and the cutter, wherein the first paper support part comprises a first proximal portion adjacent to the paper feed slot and a first distal portion at an end of the first paper support part opposite from the proximal portion. wherein the second paper support part comprises a second proximal portion adjacent to the paper feed slot and a second distal portion at an end of the second paper support part opposite from the second proximal portion, wherein a height of the first paper support part, measured with respect to a bottom portion of the paper shredder, is smallest at the first proximal portion, gradually and continuously increases as the first distal portion is approached from the first proximal portion, and is greatest at the first distal portion, wherein a height of the second paper support part, measured with respect to a bottom portion of the paper shredder, is smallest at the second proximal portion, gradually and continuously increases as the second distal portion is approached from the second proximal portion, and is greatest at the second distal portion.
