Abstract
In an image scanning apparatus, documents on a document tray are transferred one by one, and an upper surface height of the documents is lowered to turn off a height detection sensor. Different kinds of control modes are performed according to a document scanning mode. In an image-quality-priority scanning mode, a transfer unit suspends transfer of the document, the document tray is elevated until the upper surface height reaches a target height that is higher by a predetermined distance after the height detection sensor is turned on, and the transfer unit resumes the transfer of the document. In a speed-priority scanning mode, while the transfer of the document is continued by the transfer unit, the document tray is elevated until the document tray reaches the target height.
