Abstract

When a multi-feed of a document is detected, an image reading device acquires a document width from image data generated by a reading unit reading a leading end portion of the document. The document width is a length of the document in a width direction intersecting a transport direction. When, based on the document width, the size of the document corresponds to a specific size of a plastic card or an instant film, the image reading device does not execute error processing in response to an occurrence of the multi-feed, and when the size of the document does not correspond to the specific size, the image reading device executes the error processing.
