みが用紙面に当接する。In a device such as a printer or an image scanner of an OCR (optical character reading device) that needs to accurately set a printing position or a reading position of information, all sheets having different widths are fixed to a paper feed table. A structure is adopted in which a reference side guide provided at a position guides and feeds paper. In this case, since the position of the roller pieces on the roller shaft is set according to the width of each sheet from the reference side guide, the intervals between the roller pieces on the roller shaft are unequal. In the paper feeding device having such a structure, all roller pieces are in contact with the paper surface when feeding the paper of the maximum width that can be fed, and when feeding a narrow paper, the rollers within the paper width are fed. Only the piece touches the paper surface.

ーが発生しやすくなる。In order to feed a sheet without skew in the sheet feeding device having the above structure, a plurality of roller pieces arranged within the sheet width have the same pressure. It must be pressed against the paper surface. For example, as shown in FIG. 3, when the parallelism between the roller shaft 1 and the paper feed table 3 is deviated due to an assembly error between the roller shaft 1 and the paper feed table 3, one side of the roller piece may be a sheet of paper. It is pressed against the surface strongly, the roller piece on the other side floats up from the paper surface or the pressing force becomes small, the balance of the paper feeding force is lost, and it is easy for paper misfeeds and paper skew to occur in the lower-layer paper. .

決している。In the present invention, a plurality of roller pieces 2 each having a short length are fixed to one roller shaft 1 and these roller pieces 2 are stacked on a sheet feeding table 3. 2. Description of the Related Art In a paper feeding device that performs a paper feeding operation by rotating in contact with the upper surface of a sheet, a window cut out from the paper feeding table or a top surface of the paper feeding table is provided at each of the portions of the paper feeding table 3 facing the plurality of roller pieces 2. The above problem is solved by forming the concave portion 4 in which the concave portion is formed.

る。In a sheet feeding device capable of feeding a plurality of types of sheets having different sheet widths, three sheets or more, usually 4 to 6 sheets.
Although about one roller piece 2 is provided, in the structure of the present invention, many types of paper are used, and accordingly, the number of roller pieces mounted on one roller shaft 1 is large and the arrangement thereof is unequal. Devices that are spaced or asymmetrical are more effective.

ラピースと用紙との押接力も増大する。When such a window or recess 4 is provided so as to face each roller piece 2, when the sheet 5 is strongly pressed by a part of the roller pieces 2, the sheet 5 is opened through the window or recess 4. It locally bends to the side to relieve the pressing force of the roller piece 2. Further, since the space between the roller shaft 1 and the upper surface of the paper feed table becomes narrower than the case where the window or the recess 4 is not provided due to the above-mentioned bending of the paper 5, the pressing force between the roller piece and the paper, which tended to float up, is pushed. The contact force also increases.

押圧力を平準化するように働く。This action is not limited to the case where the pressing force of the left and right roller pieces varies because the roller shaft 1 is inclined with respect to the surface of the paper feed table. When the pressing force of the roller piece 2 varies randomly due to an error, or when the roller shaft is bent by the biased reaction force acting on the roller shaft when feeding a paper having a small width, the pressing force is generated. With respect to all of the variations of the above, it works so as to equalize the pressing force of all the roller pieces that come into contact with the paper.

作用も大である。Therefore, the structure of the present invention is particularly applicable to a sheet feeding device in which a wide variety of paper widths are used, and therefore, the number of roller pieces 2 is large and the arrangement of the roller pieces 2 is unequal and asymmetric. It is valid. Further, in the structure in which such a window or recess 4 is formed in a planar U-shape on the front edge portion of the paper feed tray 3, the bent paper is sent to the window or recess 4 side as it is, and therefore the paper No local resistance load is generated in the bent portion, and the leading edge portion of the paper is bent, so that the bent portion is easily bent. Therefore, the leveling action of the pressing force of the roller piece 2 is large.
