    摘要: 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 visible image is developed. The exposing is carried out by repeating a predetermined-period exposure at a predetermined interval against the same portion of the recording sheet. The printing operation of the printing system is executed by control means in accordance with a predetermined sequence.

    摘要: 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. In this case, the photosensitive and developer papers are superposed on each other for development of the latent images due to the chemical reaction between the photosensitive and developer materials. After the development, the two papers are separated from each other by a separating device such as a roller separator.
