Abstract
Abstract A thermal recording device has a thermal head section and a drive section. The thermal head section is comprised of a common electrode provided on an insulation member, an insulation layer with an opening provided on the common electrode, a plurality of recording resistive elements formed on a part of the insulation layer and the insulation member, and a connection conductor layer provided on the common electrode, which is connected to the common electrode through the opening, and to one end of each of the resistive elements. The drive section selectively feeds current to the resistive elements selected according to the data to be recorded.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
152 words
A thermal recording device comprising: a thermal head section which includes at least one recording unit for recording data on a thermal sensitive medium, said recording unit including a plurality of resistive elements formed on a surface of an insulation member, and a common electrode formed on said surface for connecting one end of each of said resistive elements corresponding to said recording unit; and a drive section connected between said common electrode and the other end of each of said resistive elements for selectively feeding current into said resistive elements according to data to be recorded; wherein said thermal head section comprises an insulation layer provided on said common electrode and having an opening which is provided at a position on said common electrode, and a conductive layer provided on said insulation layer for coupling said common electrode with said one end of each of said resistive elements, through said opening.
