  • Method for manufacturing thermal recording device
    Patent number: 5252182
    Abstract: A method for processing a wiring fraction of on a heat-generating resistance of a thermal recording device, having different thicknesses at different regions are using a masking process or a dual exposing process, so that a height difference between the heat-generating resistance and the wiring is dualized and the contact pressure between a thermal recording paper and the heat-generating resistance is maximized, thereby enabling a high quality printing operation with low power consumption.
