Abstract

PURPOSE:To obtain a copy which has high resolution and also has good reproducibility at the time of color copying by copying an image on photosensitive paper by utilizing characteristics of a positive film, and thus using no toner. CONSTITUTION:An original 1 is placed on a transparent mount table 29 and light from a visible light source 8 is scanned on the original surface to expose the surface of the positive film 11 to the scanning light. This positive film 11 is developed as specified, but the photosensitive paper 5 is mounted on the transparent mount table 29 replacing the original 1 and the positive film 11 is irradiated with light from an exposure light source 20, which is exposed to the transmitted light. Then the specific pressure fixation processing of the photosensitive paper 5 is carried out to obtain a copy. Thus, the image is copied on the photosensitive paper 5 by utilizing the characteristics of the positive film 11 and no toner is used, so the resolution of the copy is improved; and the copy of excellent picture quality with color reproducibility is obtained at the time of color copying.

In the case of a positive image formed by the red filter 12, a cyan interference filter 22 is set as the ultraviolet decomposition filter 21. Then, the transmitted light passes through the transparent portion of the positive film 11 and undergoes a photocuring reaction only with the cyan color-forming base material on the photosensitive paper 15, exposing only that portion. In this way, once the part of the ultraviolet decomposition filter 21 corresponding to the red filter 22 has been exposed, the next step is to switch to a positive image corresponding to the green filter 13, set the ultraviolet decomposition filter 21 on the magenta interference filter 23, and use the light source to light the image. irradiate. At this time, the magenta coloring base material on the photosensitive paper 5 undergoes a photocuring reaction and is exposed to light. Similarly, for exposure of a positive image corresponding to the blue filter 14, the yellow interference filter 24 is set and the yellow colored base material portion on the photosensitive paper 5 undergoes a photocuring reaction. In this way, after the exposure processing of each basic primary color of cyan, magenta, and yellow is completed, the photosensitive paper 5 is conveyed to the pressure roller 26 by the document conveyance belt 4, and is passed between the pressure rollers 26 so that it is not photocured. The microcapsules of the colored base material are destroyed, and a color fixing process is performed. In other words, on the photosensitive paper where only the cyan coloring base material 11 is photocured, red is produced by the combination of magenta and cyan, the area where only the magenta coloring base material is photocured is green, and furthermore, only the yellow coloring base material is photocured. The photocured portion will appear blue. Therefore, a color copy is made using the desired coloring material. Furthermore, by storing the film, color copies of originals that have been copied can be made by simply setting the film. In addition, if the visible light decomposition filter 9 is set on the transparent film 15, the positive film 1 becomes transparent except for the black part of the original 1.
1 is obtained, and by applying light transmitted through the cyan, magenta, and yellow interference filters of the ultraviolet light decomposition filter 21 to this, a monochrome copy can be obtained.

Incidentally, as shown in FIG. 6, by opening and closing the document table opening/closing cover 28, it is also possible to copy books, magazines, and the like.
