Abstract
An image reading apparatus includes a first unit, a second unit that is pivotable against the first unit, and a controller. The first unit includes a platen, a member, and a movable first reader. The second unit includes an original tray, a conveyance unit that conveys an original from the original tray, a static second reader. The controller determines an opening/closing state of the second unit against the first unit based on read data obtained when the second reader reads the member. The first reader reads the first side of an original conveyed by the conveyance unit and the second reader reads the second side of the original when the original placed on the original tray is read. The first reader reads the first side while moving under the original when the original placed on the platen is read.
