Claims (1)

[Scope of Claim for Utility Model Registration] A sheet aligning and feeding mechanism having a conveyance path having a reference surface that regulates the running direction of the sheet, and a feed roller that conveys the sheet parallel to the reference surface on the conveyance path, at least two or more aligner rollers provided on the conveyance path so as to be in pressure contact with each other; a support member that rotatably supports each of the aligner rollers independently; and an aligner roller of each support member that is independently rotated in the direction of the reference plane. and a plurality of sensors that detect the passage of the sheet on the conveyance path, and calculates the presence or absence of detection between the sensors and the detection time difference, and calculates the skew direction and amount of the sheet. The method is characterized in that the drawing timing and drawing order of each aligner roller are selected based on the detection result, and the sheet is drawn to the reference surface by the friction of each aligner roller drawn in this selection. Sheet alignment and feeding mechanism.
