Abstract
Abstract Apparatus is provided for use in color printing systems wherein an image is projected by a plural monochrome pictures corresponding to the pictures separated into three primary colors onto an imaging sheet which contains a dye and a photosensitive composition encapsulated in a layer of pressure rupturable capsules. The imaging sheet projected the image is positioned so the layer of capsules lies between the imaging sheet and an image-receiving sheet. A pressure roller applies pressure against the imaging sheet and the image-receiving sheet to rupture the capsules between them and thereby transfer the dye to the image-receiving sheet.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
102 words
Apparatus for forming an image on an image-receiving sheet, comprising: an imaging sheet coating with rupturable dye-containing capsules; means for making a plural monochrome pictures on a light-sensitive plate, corresponding to the pictures separated into three primary colors; means for projecting said monochrome pictures onto a light-receiving station by lights of which wavelengths are different from one another; means for moving said imaging sheet past said light-receiving station; 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
Dependent Claim
102 words
Apparatus for forming an image on an image-receiving sheet, comprising: an imaging sheet coating with rupturable dye-containing capsules; means for making a plural monochrome pictures on a light-sensitive plate, corresponding to the pictures separated into three primary colors; means for projecting said monochrome pictures onto a light-receiving station by lights of which wavelengths are different from one another; means for moving said imaging sheet past said light-receiving station; 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
21 words
The apparatus described in claim 1, wherein: said light-sensitive plate comprising a material changed electrical resistance of it by projecting light.
Claim 4
Dependent Claim
146 words
Apparatus for forming an image on an image-receiving sheet, comprising: an imaging sheet which is connected one-end of it with the other-end of it, so the imaging sheet form a ring; a capsule supplying device having dye-containing capsules which are diffused into a liquid medium, and supplying said dye-containing capsules to a surface of said imaging sheet; means for making a plural monochrome pictures on a light-sensitive plate, corresponding to the pictures separated into three primary colors; means for projecting said monochrome pictures onto a light-receiving station by lights of which wavelengths are different from one another; means for moving said imaging sheet past said capsule supplying device and light-receiving station consecutively; 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
Dependent Claim
146 words
Apparatus for forming an image on an image-receiving sheet, comprising: an imaging sheet which is connected one-end of it with the other-end of it, so the imaging sheet form a ring; a capsule supplying device having dye-containing capsules which are diffused into a liquid medium, and supplying said dye-containing capsules to a surface of said imaging sheet; means for making a plural monochrome pictures on a light-sensitive plate, corresponding to the pictures separated into three primary colors; means for projecting said monochrome pictures onto a light-receiving station by lights of which wavelengths are different from one another; means for moving said imaging sheet past said capsule supplying device and light-receiving station consecutively; 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
15 words
The apparatus described in claim 3, wherein: said imaging sheet comprising an insulative sheet material.
