Definitions
- the thickness of the outermost layer is considerably increased, the durability of the protective coating can be improved.
- the thermal response is poor due to the increase in thickness from the heating resistor to the paper, and the print quality is low. I can't get it.
- Et al is, for resistance against electrostatic breakdown, oxide Se la Mi click, S i C and S i 3 N 4 is Ho O and does etc. conductive force stuffiness, this and force, et al., The paper When sliding, the outermost layer may be charged by friction and cause electrostatic breakdown. Adding a conductive substance to prevent this eliminates the risk of electrostatic breakdown.However, water droplets and the like adhere to the surface and dissolve by ionization. The erosion problem was reciprocal. Disclosure of the invention
- a substrate, an electrode pattern formed on the substrate to have a common electrode and a plurality of individual electrodes, and a plurality of electrodes connected to the electrode pattern are provided.
- a thermal print that includes a heating dot, and a protective coating in which a plurality of layers are stacked on the substrate so as to cover the electrode pattern and the heating dot.
- the outermost layer of the protective coating is composed of SiC as a main component, and contains carbon as an additional component, thereby providing a thermal print head.
- the sputtering is a reactive snorting.
- FIG. 2 is a sectional view taken along the line 11-11 in FIG.
- a thick-film heating resistor 5 that extends linearly is formed so as to intersect with the extension 30 a of the common electrode 30 and the individual electrode 31.
- the portion defined by the extending portion 30a acts as a unit heat generation dot 50, and the corresponding drive IC power (not shown)
- the heating dot 50 generates heat due to the current.
- the heating resistor 5 is formed, for example, by printing and firing a resistor paste containing ruthenium oxide.
- the thermal print head 1 covers the electrode pattern 3 and the heating resistor 5 so as to cover the protection core.
- One tent 8 is formed.
- the protective coating 8 includes a thick glass layer 81, a thin glass layer 82, an underlayer 83 as an adhesive layer, and an outermost layer 8 which directly contacts the paper. It has a multi-layered structure with four layers (4).
- the thick glass layer 81 has a thickness of, for example, about 10 m and a Vickers hardness S 5 by printing and baking using a glass space.
- C-SiC containing carbon (C) as an additive component has a densified structure that is functionally superior to pure silicon carbide (SiC).
- various film properties especially abrasion resistance and slidability
- the improvement of the film characteristics will be described later.
- C — S i Since the C film has a slight conductivity, when the outermost layer 84 composed of the film is in contact with the common electrode 30 or the like, it is generated by friction when sliding on paper. Static electricity can be dissipated, preventing electrostatic discharge and other problems.
