Abstract
In order to provide an approximately straight line of light on an original document that is to be read, for example, by an image reading system, a light-supplying optical device includes a light source that produces a bow-shaped (i.e., curved) line of light in order to nullify the line bow phenomenon caused by an optical member such as, for example, a toric mirror that reflects the light towards the original document.
