Abstract

PURPOSE:To reduce the unevenness of irradiation to an original and to carry out exposure in the wide range of a photosensitive material by disposing a cylindrical halogen lamp in which the light quantity in both end parts is made larger than the light quantity in a center part on both sides of an original platen. CONSTITUTION:Shades 8a and 8b whose angles can be freely changed are respectively installed on both sides of the original platen 4. And light source supporting members 9a and 9b consisting of arms which move following the original platen 4 are equipped and the cylindrical halogen lamps 8 for illuminating the original, in which the light quantity in both ends is made larger than that near the center part, are mounted on the light source supporting members 9a and 9b. In the used halogen lamp 8, filaments 14 and 15 inside a bulb 13 are densely arranged in both end parts and roughly arranged in the center part. Thus, ideal lighting without unevenness of irradiation can be attained and the projection and exposure of the original in a wide area can be executed.
