Abstract
Abstract An apparatus is provided for use in color printing systems wherein an image is projected by a plurality of monochrome pictures corresponding to the pictures separated into three primary colors onto an imaging sheet which contains in layers pressure rupturable capsules, each encapsulating a dye and a photosensitive composition. The plural monochrome pictures are made by a laser scanner unit on the surface of a photosensitive drum according to image information and are transferred from the surface of the photosensitive drum to a transparent film. The transparent film is moved between a light source unit and a projection lens unit to project the plural monochrome pictures onto the imaging sheet.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
An apparatus for forming an image on an image-receiving sheet, comprising: an imaging sheet coated with microcapsules sealing therein a photo-reactive composition and a chromogenic materials; a laser scanner unit for forming a plurality of latent images corresponding to the images separated into three primary colors on the surface of a photosensitive drum according to image information; a developing unit for developing the latent images on the surface of said photosensitive drum as toner images; a film transferred said toner image from the surface of said photosensitive drum for projecting said toner images onto said imaging sheet by being interposed between a light source unit and a projection unit; and means for pressing said imaging sheet and said image-receiving sheet with said capsules coating face of said imaging sheet facing said image-receiving sheet, so the layer of capsules lies sandwiched between said sheets.
Claim 2
Independent Claim
143 words
An apparatus for forming an image on an image-receiving sheet, comprising: an imaging sheet coated with microcapsules sealing therein a photo-reactive composition and a chromogenic materials; a laser scanner unit for forming a plurality of latent images corresponding to the images separated into three primary colors on the surface of a photosensitive drum according to image information; a developing unit for developing the latent images on the surface of said photosensitive drum as toner images; a film transferred said toner image from the surface of said photosensitive drum for projecting said toner images onto said imaging sheet by being interposed between a light source unit and a projection unit; and means for pressing said imaging sheet and said image-receiving sheet with said capsules coating face of said imaging sheet facing said image-receiving sheet, so the layer of capsules lies sandwiched between said sheets.
Claim 3
Dependent Claim
27 words
The apparatus described in claim 1, wherein: said toner images on said film are projected through each of yellow, cyan and magenta filters onto said imaging sheet.
Claim 4
Independent Claim
137 words
An apparatus for forming an image on an image-receiving sheet, comprising: an imaging sheet coated with microcapsules sealing therein a photo-reactive composition and a chromogenic materials; a laser scanner unit for forming a plurality of latent images corresponding to the images separated into three primary colors on the surface of a photosensitive drum according to image information; a transfer unit having a dielectric film for receiving said latent images from the surface of said photosensitive drum, being developed by a developing unit and being interposed between a light source unit and a projection unit to project the developed images onto said imaging sheet; and means for pressing said imaging sheet and said image-receiving sheet with said capsules coating face of said imaging sheet facing said image-receiving sheet, so the layer of capsules lies sandwiched between said sheets.
Claim 5
Independent Claim
137 words
An apparatus for forming an image on an image-receiving sheet, comprising: an imaging sheet coated with microcapsules sealing therein a photo-reactive composition and a chromogenic materials; a laser scanner unit for forming a plurality of latent images corresponding to the images separated into three primary colors on the surface of a photosensitive drum according to image information; a transfer unit having a dielectric film for receiving said latent images from the surface of said photosensitive drum, being developed by a developing unit and being interposed between a light source unit and a projection unit to project the developed images onto said imaging sheet; and means for pressing said imaging sheet and said image-receiving sheet with said capsules coating face of said imaging sheet facing said image-receiving sheet, so the layer of capsules lies sandwiched between said sheets.
Claim 6
Dependent Claim
28 words
The apparatus described in claim 3, wherein: said developed images on the transfer unit are projected through each of yellow, cyan and magenta filters onto said imaging sheet.
