PURPOSE:To realize an exposure of pictures in both the going and coming-back movements of an original, by using two rocking mirrors plus an optical path passing a fixed mirror of the 1st reflection system in the going movement of the original and then rocking the two mirrors and using an optical path passing the 2nd reflection system in the coming-back movement of the original respectively. CONSTITUTION:When an original 2 which is irradiated by a lamp 1 moves right, an original image is reflected by the 1st rocking mirror 5 to be sent to the 1st reflection system 8 comprising fixed mirrors 6 and 7. Then the original image is reflected again by the 2nd rocking mirror 9 to reach a drum 10. When the original 2 moves to the left, both the mirrors 5 and 9 rock toward the 2nd direction. The original image is reflected by the mirror 5 and then by a fixed mirror 11 of the 2nd reflection system 12 and reflected again by the mirror 9 to reach the drum 10. |
