Abstract
An image reading apparatus may be in a state where a foreign material detection process cannot be completed for all reading position candidates before a sheet arrives at a conveyance roller. In such a state, the image reading apparatus performs the foreign material detection process and a position determination process only on reading position candidates which are part of all reading position candidates. The image reading apparatus determines a reading position candidate with fewest foreign material images from among the reading position candidates for which the foreign material detection process has been completed, as a sheet reading position.
