An image reading apparatus includes a main body, a rotation unit supported on the main body so as to be rotatable around a rotation axis, an imaging unit that is mounted on the rotation unit at an outward position in a radial direction of the rotation axis and images a medium to be read that is placed on a placement surface located under the rotation unit in the vertical direction, and a light source that irradiates the medium to be read with light. The light source and the imaging unit can be arranged with a relative positional relationship capable of suppressing specular reflected light of light that is emitted from the light source and reflected by the medium to be read from being incident on the imaging unit.
