Abstract
An image reading apparatus including: an image sensor unit having a light source that irradiates light onto an original document transferred to a predetermined image reading position, and a light receiving element that receives reflected light of the light; a white reference member for shading correction, provided so as to oppose the image sensor unit across a transferring path for the original document; an actuator that adjusts a position or an angle of the white reference member; and a control device that sets a position or angle of the white reference member and controls the actuator so as to adjust the white reference member to the set position or to the set angle, so that light reflected from the white reference member is received on the light receiving element when correcting shading, and so that the reflected light is not received on the light receiving element when reading an image.
