    摘要: The partial projected glaze portions (32,33,51) is formed by two projected portions (32a, 32b, 33a, 33b, 51a, 51 b). The plurality of heating resistor elements (34, 35, 52a, 52b) are disposed on at locally upper projected portions (32b, 33b, 51b) of the partial projected glaze portions (32,33,51). Both electrode end portions (58a, 58b) of the heating resistor elements (34, 35, 52a, 52b) are disposed on the partial projected glaze portion (32, 33, 51) except for the locally upper projected portions (32b, 33b, 51b). The contact area portions between the heating resistor elements (34, 35, 52a, 52b) and the recording paper (14) are uniformed and the difference of the printing density is gotten rid of. The long sideways of the recording dot (57) can be corrected.

    摘要: A thermal transfer printer including a thermal head (l), and a flat platen (l4) positioned against the thermal head through a printing sheet (9). The thermal head has a substrate (2) formed of heat insulating material, at least one glaze layer (3) on a top surface of the substrate extending longitudinally thereof, a plurality of heat generating elements (4) on the glaze layer, a plurality of electrodes (5, 6) each connected to the heat generating elements in a manner to form an opening (A) for the heat generating elements and a protective layer (7) for preventing the electrodes and heat generating elements from contacting the printing sheet to avoid their wear. A portion of the protective layer (7) for protecting the heat generating elements has a height (H₃) which is greater by more than 5 µm than the height (H₄) of a portion of the protective layer (7) for protecting the electrodes (5, 6). The width (w) of the glaze layer (3) as viewed transversely of the substrate (2) is less than 200 µm at a location which is l0 µm below a top surface of the portion of the protective layer (7) for protecting the heat generating elements (4) in a vertical direction. The deflection of the flat platen (l4) caused to occur by a biasing force exerted on the thermal head (l) is more than 0.02 time and less than twice as great as the height (h) of the glaze layer (3).
