Abstract

PURPOSE:To reduce the relative motion between a gate and a sheet and to prevent the sheet from being damaged by setting the moving direction of the gate where the sheet is brought into contact to correct skewing of the sheet same as the transport direction of the sheet transported by transport rollers. CONSTITUTION:A sheet 1 supplied in direction of an arrow A is clamped between a pair of transport rollers 2a, 2b and transported in the direction of an arrow B. The sheet 1 is brought into contact with a pair of gates 3a, 3b arranged side by side along the perpendicular direction to a side guide 4, whereby the skewing of the sheet is corrected. In this case, the leading edge portion 1a of the sheet 1 is detected by a photo sensor 6, and on detection, the respective gates 3a, 3b are moved in the same directions Z1, Z2 as the direction B of transporting the sheet 1 synchronously with the movement of the sheet 1. The side edge portion 1b of the sheet 1 is brought into contact with the side guide 1 to position the sheet laterally, and then the respective guides 3a, 3b are retreated downward C not to interfere with the sheet 1 in moving to the left.

Normally, in an image forming apparatus, especially in an apparatus such as a copying machine that is configured to obtain an image by transferring a toner image formed on a drum onto a sheet of paper conveyed through a paper conveyance path, the sheet of paper is conveyed diagonally. If the paper is transported with a misalignment in the width direction, the image may be transferred to the paper in a misaligned position before it is transferred to the drum, or the image may be transferred to the paper with a misaligned position regardless of whether it is transferred before or after transfer. The paper gets caught in the conveyance path, causing problems during conveyance such as paper jams.

By the way, in the conventional paper aligning device described above, after the paper 1 is brought into contact with the gates 3a and 3b to correct the skew of the paper, the paper 1 is further moved in the direction of arrow B to position the paper 1 in the width direction. Therefore, the gates 3a and 3b move from the initial position shown by the solid line to the position shown by the eclipse with the arrows x1. In the x2 direction,
It is configured to move in synchronization with the movement of the paper 1.

It slides against a and 3b, and a frictional force is generated there. It has been confirmed through experiments that the frictional force at this time is a relatively large value of about 202. Therefore, in order to overcome the frictional force and transport the paper, not only is a large conveying force required, but there is also a risk that the frictional force may cause problems such as the edges of the paper to be bent or damaged.

Now, the paper 1, which has been conveyed from the right side in the figure along the left direction of the arrow, is being held between the transport rollers 2a and 2b and moving along the arrow B.
transported in the direction. Next, the paper 1 comes into contact with a pair of gates 3a and 3b which are waiting at the initial position shown by solid lines. At this time, the gate is connected to the side guide 4 as described above.
Since they are juxtaposed along the direction perpendicular to
As shown by the solid line in the figure, the skew of the paper 1 is corrected. On the other hand, when the paper 1 comes into contact with the gates 1-33, 3b, the photo sensor 6 detects the front edge 1a of the paper 1, and the gates 3a, 3b are activated to prevent the movement of the paper 1 from damage. Further, in order to prevent the paper 1 from being skewed again, the paper 1 starts moving in the directions indicated by the arrows Zl and Z2, respectively, in synchronization with the movement of the paper 1. At this time, since the moving direction of paper 1 (direction of arrow B) and the moving direction of each game 1-32, 3b (direction of arrow z1, z2) are almost the same, each game 3a, 3b and its corresponding There is almost no relative movement between the front edge 1a of the sheet and the leading edge 1a of the sheet. As each gate 3a, 3b and the paper 1 continue to move, the side edge 1b of the paper 1 comes into contact with the side guide 4, and the paper is fed to an element related to image formation such as a drum (not shown) located on the left side of the figure. Positioning in the width direction of the paper is performed when printing. Gate 3a.
