Abstract
An electric recording system is a novel recording system using an electric heat recording sheet comprising an electric conductive layer and an electric resistant layer, and heating the electric resistant layer by feeding a signal current to the recording sheet by contacting an electrode needle with the recording sheet and recording symbols or figures on the recording medium (e.g., commercial thermo-sensitive paper) through the electric conductive layer. In the other embodiment of the electric heat recording sheet, an electric resistant layer is formed on one surface of an electric conductive layer and an ink layer is formed on the rear surface of the electric conductive layer whereby heat is transferred from the electric resistant layer to print shape image by printing a part of the ink layer on the recording medium, such as a regular paper. In the improved embodiment of the electric heat recording sheet, an electric resistant layer is formed on one surface of the electric conductive layer and a dielectric layer of a polymer film is formed on the rear surface of the electric conductive layer whereby the electric heat recording sheet having excellent recording characteristics and durability is prepared.
