PURPOSE:To add desired information onto an original image to have multiple functions by writing desired information, which is stored in an image processing unit through an image sensor optical system, on a photosensitive body in addition to the bicolor copying function. CONSTITUTION:The luminous flux from a light source 2 is divided to luminous fluxes 13 and 14 by a half mirror 7, and they are directed to photosensitive bodies 11 and 12, and five, all black, all red, black-and-red, white-on-red, and white-on-black modes are prepared for a bicolor image. In case that optional various information other than the original image are added to the original image, the luminous flux is taken out by a half mirror 5, and signals of information stored in an image processing unit 74 through an image sensor 73 are sent to an eraser 20 and are written on the photosensitive body 11, and this information is added to the original image formed already on the photosensitive body 12. Thus, not only the original image is reproduced in various modes but also required information is copied additionally to the original image, and multiple functions are provided with an inexpensive constitution. |
