An image reading apparatus includes a support section in contact with a mounting surface on which the apparatus is mounted, an apparatus body including a reader, the apparatus body, and a position holding section. The position of the apparatus body can be switched between a first position in which the apparatus body is not in use and a second position in which the apparatus body reads a document using the reader, and in which a projected area of the apparatus body on the mounting surface is larger than that in the first position, and the center of gravity of the apparatus body is lower than or equal to a rotation axis center of the apparatus body in a vertical direction viewed in a rotation axis direction of the apparatus body when the apparatus body is in the first position or in the second position.
