ABSTRACT:
A color thermal recording paper and a laminate sheet are pressed by urging of a press roller toward a transporting roller so as to contact each other tightly. When the recording paper and the laminate sheet pass by a ultraviolet lamp, ultraviolet rays are applied to them. The ultraviolet rays passes through a transparent sheet layer of the laminate sheet and is absorbed into an adhesive layer disposed under the transparent sheet layer. Ultraviolet-curing adhesive agents constituting the adhesive layer are hardened by the energy of the ultraviolet rays so that the adhesive layer is integrally adhered to a protect layer of the recording paper without gap. When the recording paper and the laminate sheet are adhered, heat is not used so that a cyan heat sensitive color layer of the recording paper which is not fixed by the ultraviolet rays is prevented from coloring. Accordingly, a recorded image is not changed in quality.
