(under subclass 316.1) Subject matter which includes additionally a source of infrared radiation and a sheet type document having visual information thereon which information
selectively absorbs the radiation from the source to form a thermal image of the information thereon, the responsive surface being responsive to the thermal image to cause the recording means, a copy sheet, to form a latent or visual duplicate of the information.
(1) Note. A document for this subclass is a two-dimensional sheet of paper which has on one or both sides of the sheet visual information in the form of a graph, picture, writing, handwritten or printed, from which a duplicate is to be made.
(2) Note. The copy sheet is both the detector and the recording means.
