Abstract
PURPOSE: To obtain the light source unit of good utilization rate of light and easy removal of heat from lamp by making use of the total reflection characteristics of the inside surface of a glass plate as the light transmitting means of the optical system for original exposure.
CONSTITUTION: A pair of rail-form glass holders 2a, 2b provided on the inside surface of side plates 1a, 1b are holding a glass plate 3. A long mirror 5 in trough form is fixed to the side plates by means of holders 4a, 4b. The mirror 5 is so designed that its sectional shape becomes elliptical and a bar-form lamp 6 is disposed along its linearily long first focus. The linearily long second focus is placed near the end face 3a of the glass plate. The glass plate transmits light under the same principle as that of an optical fiber and its end face 3b is disposed near the exposure plane. Since the glass plate interposes as an intermediate light transmitting means, the original exposure plane and the lamp are kept apart and the removal of the heat of the lamp is easy.
