Patent ID: 10516794

Abstract:
An image reading apparatus includes an image reading unit, a document pressing unit, a first position detection unit, a second position detection unit, and a controller. The image reading unit reads an image of a document. The document pressing unit presses the document against a document placement component. The first position detection unit detects a first closed position at which the document pressing unit is not in contact with the document placement component. The second position detection unit detects a second closed position that is closer to the document placement component than the first closed position is. The controller performs first width detection on the document and further performs second width detection. The first width detection is performed in accordance with detection performed by the first position detection unit on a closing operation of the document pressing unit. The second width detection is performed after elapse of a predetermined time in accordance with detection performed by the second position detection unit on the closing operation of the document pressing unit. If the controller receives an image reading instruction before the elapse of the predetermined time, the controller performs the second width detection without waiting for the elapse of the predetermined time and starts an image reading process.
