PURPOSE:To form many original images on a single form by providing a lens array which forms plural original images at vertically different positions in an original scanning direction and a repetitive exposing means which forms original images on a photosensitive body at different positions in the original scanning direction. CONSTITUTION:The lens array 1 consists of three lenses 1a-1c, which are arrayed on a plane optically parallel to an exposure point of an original and an exposure point on the photosensitive drum. The lens 1a forms an original image 15a1 on the photosensitive drum, the lens 1b forms an original image 15b1, and the lens 1c forms an original image 15c1 respectively. Then when the original drum 3 makes one turn and the front end of the original reaches the exposure point, the photosensitive drum 2 begins to rotate again to form original images 15a2-15c2 at the different position in the original scanning direction. Further, when the original drum 3 makes one turn, original images 15a3-15c3 are formed on the photosensitive drum at successive position sin the original scanning direction. |
