ユー補正機構。[Scope of Claim for Utility Model Registration] (1) A paper stopper that has a paper stop surface perpendicular to the paper traveling direction and that can be projected onto the paper travel path and retracted; A skew correction mechanism includes a paper conveying means that can convey paper from a paper suction and discharge port toward a paper stopper with a force that does not cause the paper to bend between the paper suction and discharge port. (2) The paper conveying means includes a feed roller rotated by a drive mechanism, a paper press roller that approaches and leaves the feed roller to open and close, and pinches the paper when pressed by the feed roller, and a paper press roller that shares a central axis with the paper press roller. It has a larger outer diameter than the paper presser roller, and when the paper presser roller is completely closed and is pressed by the feed roller, it does not prevent the paper presser roller from contacting the paper surface, and the paper presser roller A claim comprising: an auxiliary roller that is in contact with the paper when it is not pressed against the feed roller when it is closed and is not pressed against the feed roller, and is capable of transporting the paper toward the paper stopper with a force that does not cause the paper to bend between the part in contact with the paper and the paper stopper. 1. The skew correction mechanism according to 1. (3) When the paper press roller is completely closed, the peripheral edge of the auxiliary roller protruding from the paper press roller can be distorted to a position approximately equal to the diameter of the paper press roller, and the paper press roller is partially closed. 3. The skew correction mechanism according to claim 2, wherein the feed roller, in which the leading edge of the paper being conveyed sometimes hits the paper stopper, presses the paper with such force that it can slide on the surface of the paper.
