An image reading apparatus having a sheet path, which includes two ejection paths, is provided. The sheet path is switchable between the two ejection paths by a switchable member. An outlet cover arranged on a casing of the image reading apparatus is movable between a closed position and an open position to open and close an outlet of the second ejection path. When the outlet cover moves from the closed position to the open position, and before the switchable member switches the sheet path from the first ejection path to the second ejection path, switching of the sheet path from the first ejection path to the second ejection path is detectable.
