Class Information
Number: 250/317.1
Name: Radiant energy > With infrared or thermal pattern recording > Thermal copying of documents
Description: 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.
