Abstract
A copying machine in a casing has a window in the casing for visually recognizing a printing position and image pickup position, so that the printing position and image pickup position may be adjusted through the window. An illumination apparatus to be used in the copying machine is located in the casing, and the light from a light source is led onto the imaging surface by an optical guide member, which illuminates the illuminating position such as the image pickup position. Since the light from the light source can be shielded by the casing, the illuminating position can be recognized visually through the window.
