Refer to Fig. 2a. "The paper feeding device of this creation is suitable for one thing ^ ^" such as a printer or scanner, which includes a paper picking roller R, take, axis L, a movable baffle 30, a The cam 4, a paper cassette 5 and the upper cover 6 °, as shown, the movable baffle 30 is connected to a torsion spring 31, so that the broadcasting plate 3 can be rotated between a first position 3 and a second position 3, ; 'The pickup roller R is fixedly connected to the pickup shaft L, and the cam 4 can rotate around the pickup shaft l' and has a recessed portion 410, and the baffle 30 abuts against the cam 4 when the baffle 30 is in the recessed portion 410 and The baffle 30 is positioned at the first position 3 described above. In addition, the cam 4 can rotate around the paper picking axis L in a clockwise direction and drive the shutter 30 to the second 'position 3'. Among them, the paper to be fed can be placed in the paper tray 5 in advance, and when the carrier 30 is located at the second position 3, the paper can be driven forward by the paper picking roller r to complete the paper feeding action. Next, please refer to FIG. 2b, the paper take-off shaft L is disposed between the paper take-up roller R and the center of the cam 4. The paper take-out shaft [also connected to the upper cover 6 as shown in the figure. The paper roller r is separated from the lower plate 3 at the same time. At this time, the paper plate r is located at the second position 3, and the plate 3 can be restored upward by the elastic force of the torsion spring 3 丨 and is located at the first position 3 (as indicated by the arrow direction).

Among them, the baffle 3 quickly descended from the first position 3 (2C picture) to the second position 3 '(2d picture In the process of the paper s, the front end of the paper s and the baffle 3 have an instantaneous change due to the drop, so the position energy of the paper S is instantly converted into a kinetic energy. At this time, the paper located above is due to the Small friction, and a large sliding distance can be generated at the moment of falling of the fascia 3, so that it can not only drive the paper S forward naturally but be located under the pickup roller r, to avoid the iniss-feed ), While the paper S is sliding on the surface of the baffle 3, the effect of staggering and separating between the upper paper and the lower paper can be more effectively (as shown in Figure 2d). Therefore, it can be greatly improved. Know the problem of multiple paper feed (mu 11 ip 1 efe ed). Figure 2e is a schematic diagram showing that the baffle 30 can be rotated between the first position 3 and the second position 3 'by a torsion spring 31. Among them, the torsion spring 3 1 can be seen: for a reply The elastic force causes the stretcher 3 to return in the clockwise direction to be positioned at the first position 3 described above.
