のと同様の利点が得られる。[Prior art] A microcapsule containing a chromogen, a photocurable resin, a sensitizer, a photopolymerization initiator, etc. is coated on the surface with a color developer that causes a color development reaction with the chromogen inside. Photosensitive and pressure-sensitive sheets are already known, as shown in, for example, Japanese Patent Application Laid-open No. 58-23025 and Japanese Patent Application Laid-Open No. 58-88739. According to this photosensitive pressure-sensitive sheet, the microcapsules are photocured in the areas of the sheet surface that are exposed to light, and remain uncured in other areas. Therefore, when this photosensitive pressure sensitive sheet is then pressed with a pressure roller, the uncured microcapsules on the sheet surface are crushed and a color developing reaction occurs between the chromogen and the color developer, which causes the copied image to change. That's what you get. Therefore, this photosensitive pressure-sensitive sheet can produce bright images similar to electrophotography, and unlike conventional copying devices that use plain paper, maintenance is easy because it does not use toner powder. There are advantages such as There are two types of photosensitive and pressure sensitive sheets: self-coloring type and transfer type.The transfer type photosensitive and pressure sensitive sheets are coated with the aforementioned microcapsules. However, no developer is applied, and a developer sheet coated with a developer is prepared separately. After exposing the photosensitive pressure sensitive sheet, a color developer sheet is placed on top of it and pressure is applied to obtain a copied image on the surface of the color developer sheet, which is similar to the self-coloring type. Benefits can be obtained.

た。[Problems to be Solved by the Invention] However, especially in the case of a copying device in which a transfer-type photosensitive pressure-sensitive sheet is used as copying paper, after a predetermined exposure process is performed on the surface of the photosensitive pressure-sensitive sheet, When the color developer sheets are stacked and pressed by a pressure roller, if the microcapsules in the surrounding area of the photosensitive pressure sensitive sheet where the color developer sheets are stacked are uncured, they will be crushed and the color inside will be lost. A liquid substance such as a raw material or a photocurable resin may be pushed out from between the photosensitive pressure sensitive sheet and the color developer sheet. Then, the liquid substance adheres to the pressure roller surface, and the adhered substance sticks to the developer sheet, which is the side of the copied image, and stains the developer sheet, or
The liquid substance gradually accumulates on the surface of the pressure roller, eventually causing pressure fluctuations between the pressure rollers, resulting in uneven development or insufficient development.

ものである。[Object of the Invention] The present invention has been made in view of the above-mentioned problems, and its purpose is to overlay a color developer sheet on the surface of a photosensitive pressure sensitive sheet after completing a prescribed exposure process. When pressure development is carried out using the overlapping pressure rollers, uncured microcapsules on the surface of the photosensitive pressure-sensitive sheet are crushed and squeezed out from the overlapping peripheral edges, such as chromogens and photocurable resins. The purpose is to prevent the liquid substance from being pushed out and staining the surface of the pressure roller. This is intended to avoid staining and uneven development of the color developer sheet surface, particularly on the side of the copied image, and at the same time to reduce the maintenance of the pressure roller.

When the distance between 8.3b changes depending on the size of the original document 2, the optical system 15 moves in conjunction. In this case as well, the position exposed by the optical system 15 on the surface of the photosensitive pressure sensitive sheet 5 coincides with the peripheral area where the color developer sheet 8 is overlapped, and the adhesion of the liquid substance to the surface of the pressure roller 10 and 10 is prevented. In this case as well, this can definitely be avoided. Note that an angle adjustment mechanism or the like for the optical system 15 may be provided to accommodate enlargement and reduction copying, and it is not at all difficult to make such design changes as appropriate.
