Abstract

PURPOSE:To simplify the correction of revolution of picture, by providing a plurality of position detection mark on an original, obtaining the slope of the original from the number of scannings from the detection of one of these marks to the detection of the next mark and moving the scanning line corresponding to the position shift. CONSTITUTION:The detection marks M1, M2 are provided with a distance (l) on the same line according to the main scanning direction 11 of an original 10. Further, when the mark M1 is detected by the 1st scanning line and the mark M2 is detected with the n-th scanning line, the slope of the original theta is obtained as theta=np/l. An operation device 65 operates l/np, an address control device 66 reads out the video element information from a memory 62, and every time when the count value is l/np, this address control device moves the designated address toward the subscanning direction. Further, when the information corresponding to required scanning width is stored in a register 63, correction of rotation is made with the signal So for one scanning line's share.
