Abstract
PURPOSE: To let adequate lighting be effected for both modes of copying mode and original read mode by integrating a light source lamp and an oval reflecting mirror to permit relative movement with the original rest part and providing a shield plate for illuminance distribution adjustment.
CONSTITUTION: An oval reflecting mirror 2 is integrated and provided so as to nearly enclose a light source lamp over the length direction of the light source lamp 1 and a shield plate 4 for illuminance distribution adjustment has a shape wherein the central part bows so that the illuminance distributions of the lighted part become large on both end part sides of the light source lamp 1 and small near the central part. To change over from the position of I indicating photoreceptor exposure to the position for original read scanning, the oval reflecting mirror 2 and light source lamp 1 are parallel moved as illustrated in II so as to go away from the original rest glass 3, then the reflected light condenses in the slit form region of an extremely fine width on the original, lighting said region with high luminous intensity.
