Abstract: An image reading apparatus includes an output tray that receives a medium which is output thereon; an output roller pair that outputs the medium onto the output tray; an output-tray posture switching portion that switches a posture of the output tray with respect to the apparatus body; and an output-direction switching portion that switches an output direction of the medium by using the output roller pair. The output roller pair includes an output driving roller, and an output driven roller that nips the medium between the output driven roller and the output driving roller and that follows the rotation of the output driving roller. The output-direction switching portion switches the output direction of the medium by displacing a rotation center of the output driven roller around a rotation center of the output driving roller.
