Abstract
An image scanning apparatus includes a paper thickness detection unit arranged to detect a paper thickness of an original document based on a reception signal, and a multiple-feeding detection unit arranged to detect, based on the reception signal, whether or not the original document that is being transported has been multiply fed. Based on a detection result obtained by the paper thickness detection unit and the multiple-feeding detection unit, the transportation speed is adjusted.
