Abstract
An image reading apparatus, including a feed tray, a conveyance guide, a feed roller, a separator, a reading sensor, and a controller, is provided. The feed tray supports sheets for being fed and has a movable plate movable between a standby position and a feedable position. The feed roller is movable and feeds the sheets to be conveyed along the conveyance guide. A positional relation between the feed roller and an uppermost sheet in the sheets is maintained within a predetermined range by the movable plate located at the feedable position. The controller controls at least rotating-and-stopping movements of the feed roller and the separator and ascending-and-descending movements of the movable plate. While the feed roller feeds the sheets, the controller conducts a vibrating action, in which the movable plate located at the feedable position is moved to ascend and descend for a plurality of times.
