Abstract

PURPOSE:To improve cooling efficiency and to miniaturize a blowing means by providing a varying means for varying the direction of the wind of the blowing means corresponding to the movement of a scanning optical system. CONSTITUTION:A lighting lamp 3 and a mirror 4 are equipped on the 1st mirror board 28 of the scanning optical system and provided so that they can move by means of a wire 29. And a cross flow fan 27 and a flapper 27b which changes the direction of the wind are provided in a fan device 27. In the mirror board 28, a moving distance and a scanning speed can be altered according to the size of original and reduction magnification and the flapper 27 is controlled so as to turn to the direction of the mirror board 28, for example, by a flapper driving plate, etc., corresponding to the movement of the mirror board 28. Since cool wind is blown to the direction where the scanning optical system is positioned, the heat generated by the lighting lamp 3 can be effectively removed and an air cooling equipment can be miniaturized.
