Abstract: A copying apparatus operable with an original having an image-bearing surface on which images to be reproduced are supported. A radiation reflected by the image bearing surface is focused on a photosensitive paper, by a self-focusing lens array, so that latent images corresponding to the images on the image-bearing surface are formed on the photosensitive paper. The latent images are developed into visible images by a developing device such as a device adapted to apply a pressure to the photosensitive paper. The photosensitive paper may be a self-activated type having a photosensitive material and a developer material which chemically react with each other in the developing process. Alternatively, a separate developer paper having a developer material is superposed on a photosensitive paper having only a photosensitive material.

Abstract: In an optical printing system for printing an image on a recording sheet, adopted as the recording sheet is a sheet coated with microcapsules on one surface thereon. Each microcapsule envelopes a first component which changes color when reacts with a second component. The second component may be coated on the recording sheet or may be coated on a separate developing sheet. The microcapsule further envelopes a third component which varies the mechanical strength of microcapsule when light is projected thereto. An image is formed on the recording sheet by selectively exposing a light thereto in accordance with the image to be printed thereon, and the microcapsules on the recording sheet whose mechanical strength is low are then ruptured by rupturing means. Thereby, the color is developed or the recording sheet on the first component with the second component. The printing operation of the printing system is executed by control means in accordance with a predetermined sequence.

Abstract: An image recording device wherein a photo-sensitive paper or a plain paper is selected as a recording medium. If a monochrom image is to be recorded, a provisional image formed with light-shield materials which corresponds to an original image to be recorded is directly transferred onto the plain paper to form a monochrom image thereon. If a color image is to be recorded, the light-shield image is once transferred onto an image carrier, and the light-shield image carried on the image carrier is exposed on the photo-sensitive paper to form a latent image thereon. The latent image formed on the photo-sensitive paper by the above exposure is then developed to a visible color image.

The exposure platform has a surface of an excellent light-absorptive material to prevent the recording sheet from being exposed again to light reflected from the platform surface.
