According to the present invention, a regulating plate having a leading edge approaching the flat reflecting mirror is provided, and the leading edge cuts off a portion of the light directed from the document surface toward the flat reflecting mirror on the regulating plate side. Since the part of the light incident on the plane reflecting mirror from the surface and reflected from the plane is cut off on the regulating plate side, the light reaching the exposure surface can be made into a thin strip. Therefore, with an extremely simple structure in which the leading edge of the regulating plate is disposed close to the plane reflecting mirror, good original exposure can be achieved.
