The invention relates to a paper shredding mechanism which comprises paper shredding tools, a paper placing mechanism, a paper pressing mechanism and a driving motor; the paper shredding tools are arranged in two parallel rows, and a shredded paper conveying notch is formed between the two rows of paper shredding tools, and is formed at the position at one side of the paper placing mechanism and close to the middle part; the paper shredding tools are in parallel to the plane in which paper is placed, and the top ends of the paper shredding tools are slightly higher than the plane in which the paper is placed; and the paper pressing mechanism is arranged on the paper, and the direction of force (of the paper pressing mechanism) pressing to the paper is vertical to the planes of the paper breaking tools. According to the paper shredding mechanism, the paper can be shredded from the sides in which the contact surfaces of the paper and the tools are positioned, and paper conveying and paper shredding are carried out at the same time, the traditional paper shredding mode that the paper enters from one end or the paper is conveyed to tool parts through the paper conveying mechanism (or wheels) and then are shredded is changed; the paper shredding efficiency is improved greatly; the rapid is fast; the paper shredding amount is high; and the paper is not clamped.

The invention discloses a double face paper advancing device, which is used for various scanning devices such as fax machines, printers, scanners and multi-function printers. The double face paper advancing device comprises a paper taking module which is used for guiding papers to advance into a first paper advancing channel; a paper control scroll module which is used for providing a first clipping force to advance the papers to the outer part of the double face paper advancing device and a second clipping force to advance the papers into the inner part of the double face paper advancing device; a paper in-and-out module which provides a third clipping force to advance into or out the papers. The double face paper advancing device of the invention can control the moving precision of the papers thereby avoiding paper jamming.

The invention provides a paper which contains a preaggregated filler having an average particle diameter as determined by laser diffractometry of 10-80 mu m and obtained by treating a filler with a combined acrylamide copolymer comprising (A) an anionic polysaccharide and (B) a cationic and / or ampholytic acrylamide copolymer, in such an amount that the paper has an ash content of 3-40 wt.% on a solid basis. This paper is satisfactory in paper strength including strength and stiffness, has high smoothness, and attains excellent print quality.

Disclosed is a paper shredding mechanism, comprising paper shredding cutters (4), a paper placing mechanism (2), a paper compressing mechanism (3) and a driving electrical motor (1), wherein the paper shredding cutters (4) form two parallel rows, a shredded paper conveying gap (7) is provided between two paper shredding cutters (4), mounted at a position close to the centre at one side of the paper placing mechanism (2), the paper shredding cutters (4) are parallel to the plane of paper placement, with the top end being slightly higher than the plane of paper placement, and the paper compressing mechanism (3) is placed on the sheets of paper and the force of compression thereof on the sheets of paper is perpendicular to the plane of the paper shredding cutters (4). The paper shredding mechanism can begin to shred paper from the face of the sheets of paper in contact with the cutters, conveying the paper and shredding the paper simultaneously, changing the traditional paper shredding method which requires feeding paper at one end or conveys paper via a paper conveying mechanism to the cutter position and then shreds paper, thus significantly improving paper shredding efficiency, being fast, shredding a large volume of paper, and not jamming with paper.
