  • DOCUMENT CONVEYING APPARATUS CAPABLE OF CORRECTING DOCUMENT SKEW
    Publication number: 20240140747
    Abstract: A document conveying apparatus includes a correction roller, a correction portion, a biasing portion, and a regulating portion. The correction roller has a rotating shaft, and a pair of contact portions arranged spaced apart on the rotating shaft, each including contact pieces extending in radial directions from the same circumferential positions, and each capable of coming in contact with a leading edge of a document conveyed on a conveying path. The correction portion allows the correction roller to rotate only when the leading edge of the document comes in contact with both of the pair of contact portions and the skew of the document is corrected. The biasing portion biases the correction roller in a rotational direction of the correction roller. The regulating portion regulates rotation of the correction roller biased by the biasing portion so as to retract the contact pieces of the contact portions from the conveying path.
