Claims

[Scope of Claim for Utility Model Registration] A pair of left and right flap members provided on the downstream side in the paper conveyance direction, and each flap member is held independently so that it can open and close horizontally and vertically at the same time in the conveyance direction. a holding means attached to the flap member and having a biasing force set to produce a resistance force that is weaker than the conveying force of the paper, and biasing the flap member in the upper closing direction; In response to the biasing force, the flap member is always held in the closing direction at an upper position where it can come into contact with the leading edge of the paper;
and positioning means for symmetrically positioning the flap member, and when one of the flap members comes into contact with the leading edge of the sheet, the flap member is pressed by the conveying force, and
A resistance force based on the above-mentioned biasing force takes a correcting posture in which the paper is rotated from side to side, and as both flap members come into contact with the leading edge of the above-mentioned paper, the flap member is pressed by the above-mentioned conveying force and both of them are lowered. A paper skew correction device characterized by: taking a retracted position in an opening direction at .
