PURPOSE:To enable copying and development on conditions after trimming by providing a means which sets the image of an extracted area to optional magnification, a means which expose the same photosensitive medium to the image set to the optional magnification as a latent image plural times, and a means which visualizes the latent image. CONSTITUTION:An original placing table is provided at the upper part of an optical system 110 and a mask 111c which is variable in the size of an aperture part with transparent plates 11a and 11b and an original cassette 111 are set as the means for extracting an optional area in an original surface, so that size information on the aperture part is automatically inputted to the control part of a copying machine. When the desired number of copy images is inputted, magnification M is determined through the operation of the program of the control part. A photosensitive medium feed part 120 draws out and cut a rolled negative paper 122 from a magazine chamber, and an illumination lamp 112 turns on and shutters S of respective lens blocks are opened or closed at the same time to expose the photosensitive paper 122 to the image of the original D. The photosensitive paper 122 is conveyed to a processing part 130 and the latent image is visualized.
