Abstract
A moving-side roller reliably separates from a stationary-side roller so as to enable appropriate document transport. An image reading apparatus causes a roller support member supporting the moving-side roller to come into contact with the stationary-side roller. A contact state and a separation state can be switched. The image reading apparatus includes an external force providing portion to exert a third external force on the roller support member in a direction for restraining warping that is generated in the roller support member by a first external force that a cam exerts on the roller support member and by a second external force that an urging device exerts on the roller support member.
