を加えることになってしまう。SUMMARY OF THE INVENTION The above-mentioned prior art is configured to correct the conveyance deviation while conveying the paper in a plane. In order to correct the conveyance misalignment without buckling the paper in such a state, for example, the conveyance force of the diagonal feed roller should be set within a delicate range, a deep and narrow guide groove should be provided, or the movable side plate should be moved. Measures such as maintaining a high degree of accuracy are required, making the process complicated and expensive. Furthermore, since it is necessary to secure a space for conveying the paper in a planar manner, this imposes restrictions on downsizing of the main body of the image forming apparatus.

Reversing conveyance path 1a
be led to. On the way of this reversing conveyance path 1a, there is a sheet conveyance misalignment correction device according to the first embodiment of the present invention using diagonal feed rollers 26 and 28, and an intermediate conveyance device that guides the sheet that has passed through this correction device to registration rollers 10. Rollers 30 and 32 are installed. A curved portion 36 is set in the reversing conveyance path 1a between the diagonal feed rollers 26, 28 and the intermediate conveyance rollers 30, 32, which curves at least a portion of the paper being fed by the diagonal feed rollers 26, 28 downward. has been done. This curved portion 36 has a sliding surface whose upper surface is curved downward, and the paper is curved along this sliding surface by being fed in sliding contact with this sliding surface.

ており、搬送抵抗の減少に寄与している。Next, the paper conveyance deviation correcting device of this embodiment will be explained in detail with reference to FIGS. 2 and 3. First, in FIG. 2, the paper sent from the direction of arrow A to the reversing conveyance path is separated from the reference surface 34a of the reference wall 34, which is a reference element, as shown by the solid line, and a conveyance deviation occurs. Suppose that The sheet with the conveyance misalignment is sent in the direction of arrow B by the diagonal feed rollers 26 and 28, and one edge of the sheet comes into contact with the reference surface 34a as shown by the dashed line in the figure, so that the conveyance misalignment is corrected. . Thereafter, the paper is sent out in the direction of arrow C by the feed rollers 30 and 32 along the reference surface 34a. The reversing conveyance path 1a between these feed rollers 30, 32 and the curved portion 36 is set in a straight line, contributing to a reduction in conveyance resistance.

屈を防止することができる。At this time, as shown in FIG. 3, since a portion of the paper is curved along the longitudinal direction by the curved portion 36 set in the reversing conveyance path 1a, the paper is aligned with the reference surface 34.
Even while the paper continues to be in contact with the paper and receives the conveyance force in the direction of arrow B, the curved paper continues to be conveyed in the direction of arrow C by the next conveyance means, intermediate conveyance rollers 30 and 32. Buckling of the paper in the width direction can be prevented by the stiffness of a portion of the paper.

第２実施例を、図４及び図５を参照して説明する。[0017] Furthermore, if a curved part is set on the entrance or exit side of the paper conveyance misalignment correction device, the paper will rotate due to paper conveyance resistance and the correction accuracy will deteriorate, so it is necessary to set a flat part over a wide range. Therefore, it is necessary to perform a conveyance deviation correction operation. This results in a large device, but if the curved part is set near the center of the device as in this example, the effect of preventing buckling is great, so it is possible to increase the conveying force of the diagonal feed roller. This allows the device to be made compact without compromising accuracy in correcting conveyance deviations. Next, a second embodiment of the paper conveyance misalignment correcting device according to the present invention will be described with reference to FIGS. 4 and 5.

こともできる。In the apparatus of the first embodiment, a reference wall, which is a reference element, is installed on one side of the reversing conveyance path, and the paper is brought into contact with this reference wall using a diagonal feed roller. It is also possible to set a reference line, which is a reference element, at the center of the reversing conveyance path, and to align the center of the sheet with this reference line, as shown in FIG.

A first movable side plate 50 is installed on the left side of this reference line 38 when viewed from the direction of arrow D. On the other hand, on the right side of this reference line 38, a presser plate 54 is connected via two springs 52.
A second movable side plate 56 is installed. These movable side plates 50, 56 are movable in the direction of the arrow, that is, in the width direction of the gist, by driving means (not shown). As shown in FIG. 5, these first and second movable side plates 5
In front of the paper conveyance misalignment correction area formed by 0 and 56, feed rollers 40 and 42 are provided to feed the paper into this correction area. Further, behind this correction area, conveyance rollers 44 and 46 are arranged to further convey the paper whose conveyance deviation has been corrected in the direction of arrow E. In the correction area, a paper conveyance path is formed such that the paper has a curved portion 58 .

The conveyance deviation is corrected using the reference line 38 as a reference by the movable side plates 50 and 56. At this time, the paper is pressed against the first movable side plate 50 by the elasticity of the two springs 52, but as shown in FIG.
8, the conveyance deviation is corrected without buckling. Thereafter, the paper is transported in the direction of arrow E by transport rollers 44 and 46, and sent to the next process.
