PURPOSE:To attain a picture reading/recording device with a simple constitution, without producing any step difference of recording density at the boundary of adjacent reading regions, even at the reading and recording of multi-gradation, by using a light source forming an equal illuminance band over longitudinal and lateral width of a plane of an original to be read, and a reading/recording section combining integrally heads recording image on a recording medium. CONSTITUTION:When a center of the reading/recording section 20 is moved from a point A1 to a point B1, the picture information of an original plane S1 shown in broken lines for the boundary section is read and recorded, and then when the center of the reading/recording section 20 is moved from a point B2 to a point A<2>, the picture information of the original plane S2 is read and recorded, the reading/recording of original planes S3, S4 is attained similarly. Since the light source 3 is scanned reciprocatingly in longitudinal direction of the plane S of original to be read while forming the equal illuminance band over the entire lateral width of the plane S of original to be read, the uneven illuminance of the boundary section of the reading original planes S1, S2, S3, S4 to be split is eliminated and the recording without density difference is attained even if multi- gradation of reading/recording is performed. |
