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 discloses an automatic paper feeding structure of a shredder. The automatic paper feeding structure comprises a frame and a paper feeding channel formed above the frame, wherein the paper outlet of the paper feeding channel is positioned above the paper inlet of a shredding roll set of the shredder. The automatic paper feeding structure is characterized in that: a plurality of paperdistributing needle stands rotating around a fixing shaft are distributed on the fixing shaft of the frame along the axial direction; a paper distributing needle is inserted into each paper distributing needle stand; the paper distributing needles are distributed in sequence in a stepped form in the height direction along the axial direction of the fixing shaft; the needle point of each paper distributing needle faces the paper discharging direction of the paper feeding channel; the frame is provided with a camshaft which is parallel to the fixing shaft; cams which can rotate synchronously along the camshaft and are matched with the paper distributing needle seats one by one are distributed on the camshaft along the axial direction; and the cams act on the paper distributing needle seats to drive corresponding paper distributing needles to rotate towards the paper inlet of the shredding roll set in sequence. Compared with the prior art, the automatic paper feeding structure has the advantages of high paper feeding reliability and capabilities of realizing graded paper feeding and increasing the working efficiency of the shredder.

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.

The invention discloses a paper folding machine which comprises a rack, a paper folding mechanism and a driving device. The paper folding mechanism comprises an upper paper folding device (1), a lower paper folding device (2) and a synchronous belt wheel device, the upper paper folding device (1) comprises an upper paper folding baseplate (15), an upper paper pressing cam (102) and an upper paper pushing cam (101), the lower paper folding device (2) comprises a lower paper folding baseplate (25), a lower paper pressing cam (202) and a lower paper pushing cam (201), the synchronous belt wheel device comprises an upper synchronous belt wheel (30), a lower synchronous belt wheel (31) and a synchronous belt (32), two cams in the upper synchronous belt wheel (30) and the upper paper folding device (1) are coaxially and fixedly connected, two cams in the lower synchronous belt wheel (31) and the lower paper folding device (2) are coaxially and fixedly connected, and the upper synchronous belt wheel (30) and the lower synchronous belt wheel (31) is connected with the driving device. The paper folding machine can automatically fold paper to be in the shape of an accordion blade in positive and negative directions.

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.

The present invention provides a mathod of loading recording paper of printer. A rolled sheet 10 is loaded in a rolled sheet loading section 6 of a rolled-sheet printer 1. If the recording paper 10a is pulled out from the section 6 and inserted toward a nip part 19 of a paper-feed roller 17, the recording paper 10a is detected by photosensors 21, 22, then the operation of feeding the paper by the paper-feed roller 17 starts. The recording paper 10a is conveyed only by the 1st feeding rate L1 equal to the distance from the nip part 19 to a cutting position 24 of a manual cutter 23, and the recording-paper tip edge 10d is positioned in the cutting position 24. If the black mark 10c is detected by the photosensors 21, 22 before the feed rate reaches the 1st feeding rate L1, a normal feed-controlling based on the black mark is performed, then the recording-paper tip edge 10d is positioned in the cutting position 24.
