Abstract

PURPOSE:To ensure a high-speed reading with a high image resolution, by reading the fixed range overlapping partially in the direction of the secondary scanning of the original along with the reference mark put on the conveyer belt and then giving a correction to cut the picture signals on the overlapped lines. CONSTITUTION:The picture images of original 1 arriving at the position of one image pickup range P overlap successively and partially with every conveying step. The signals of partial line among those composing picture signal (a) which is delivered from image sensor 7 are delivered in overlap. In this case, not only the screen of original 1 but reference mark 2a on conveyer belt 2 is read simultaneously, and thus the signals of some lines contain the component of mark 2a. And when signal (a) is used as the reproduced picture signal, the overlap of the images occurs in the reproduced picture. And at the same time, the component of mark 2a is also reproduced. Accordingly, the signals of the overlapped lines are cut by signal process circuit 8, and also a correction is given to eliminate the component of mark 2a out of the signal of each line.
