Abstract
PURPOSE: To let the device suited for high-speed lighting scanning and increase condensing light quantity by so constituting the device that the moving axis of a scanning reflecting mirror and the moving axis of the main lighting system have mutually different inclinations.
CONSTITUTION: In the slit exposure lighting system which radiates the luminous flux emitted from the main lighting system 3 consisting of a light source 1 and main reflecting mirror 2 through a scanning reflecting mirror 4 and moves the main reflecting mirror 2 and scanning reflecting mirror 4 both diagonally, the scanning reflecting mirror 4 is moved not in the AA', BB' directions parallel to the moving direction CD of the main lighting system 3 but in parallel to the AA" line and BB" line. In this case, the length AA'>AA" of the segment and therefore the scanning distance of the scanning reflecting mirror 4 becomes short, high-speed scanning becomes possible and condensing characteristic becomes good.
