Claim One:
1. An image reading apparatus comprising: an image capturing device for capturing an image of a document; a light source; a movable light reflecting surface having a white color; a driving device for moving the light reflecting surface between a first position at which the light reflecting surface reflects light from the light source and a second position at which the light reflecting surface does not reflect light from the light source; and a control circuit for controlling the driving device to move the light reflecting surface, wherein the control circuit determines whether an image obtained by the image capturing device is a white reference image and determines, as the first position, a position where the white reference image is detected when the control circuit moves the light reflecting surface from the second position to the first position; and determines, as the second position, a position where the light reflecting surface is moved by a predetermined distance from the first position without using an image obtained by the image capturing device, when the control circuit moves the light reflecting surface from the first position to the second position.
