Abstract

PURPOSE: To eliminate uneven density of a copied image, by shifting to one side an image formed by effectively utilizing the light near the optical axis of a lens system with keeping this state, and providing an equivalent device.
CONSTITUTION: Original 1 on contact glass 2 is projected onto image sensor 8 via fixed lens system 3, this image is divided into the elements of image to convert them into digital signal 9, this is sent via image processing circuit 10 to plotter control circuit 15, and the plotter scans the record from one side in an image element division type copier. Gate 14 is provided on the transmission path between sensor 8 and circuit 15, and indicator 11 indicating the address of each photosensitive element of image sensor 8 on both ends of the image area projected on image sensor 8 in accordance with the size of the original to be copied, and means for opening gate 14 of only the video signal path between the indicated addresses by memorizing the indicated addresses from indicator 11 are provided, permitting uneven density to be avoided.
