PURPOSE:To obtain a sharp copied image without copying an original image and a display signal in density different from each other, by exposing the original image and the display signal of a liquid crystal display element through the same optical system. CONSTITUTION:An original is placed on an original platen 1, and a signal A necessary for a controller is selected and displayed on the display part 12, etc. of a signal display device 15. In copying the original, the signal A is simultaneously projected on a copying paper 7 to expose the paper 7 and to form an electrostatic latent image A'. Since the same optical system is used for exposure, the apparatus can be reduced in size, and a sharp copied image can be obtained without copying the original image and the display signal in density different from each other. |
