PURPOSE:To record a synthetic picture by providing two systems of exposure mens and by performing exposure while overlaying necessary information from the 1st system and fixed-form pattern information from the 2nd system with each other. CONSTITUTION:After a photosensitive drum 3 is charged by an electric 7, the 2nd exposure means B exposes optical picture information on an original, wherein a fixed-form pattern is entered, set on an original placing plate 4 at the position (b) of the drum 3 successively. At this time, a shutter 7 is kept open. When the drum 3 is turned next, the 1st exposure means A exposes optical picture information on documents, etc., at the position (a) of the drum 3 successibely. In this case, exposure timing is so determined that an exposed part by the 1st exposure means A and that by the 2nd means are overlaid with each other. At this time, the shutter 7 is held closed to shield the inside from external light passed through a convergent optical transmitter array 6. |
