    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).

    摘要： A combination of a printer and a ribbon cassette (45) has a mechanism for preventing a portion of the inked ribbon extending between a supply core (51) and a take-up core - (62) of the ribbon cassette (45) from shifting in the direction perpendicular to the longitudinal direction of the inked ribbon with respect to a printing head (40). The mechanism is constituted by a substantially planar surface of the platen - (13), and the printing head (40) is urged against the planar surface of the platen through the inked ribbon portion and a sheet (32) to which solid ink in the area on the inked ribbon portion is transferred by the printing head (40). The width of that area on the inked ribbon portion in the widthwise direc- ion of the inked ribbon is at most equal to a half of the width of the inked ribbon. Alternatively, the mechanism (400) is constitued by a mechanism operative in response to the variation in diameter of the inked ribbon wound on the supply core (51) for applying a variable back tension in the reverse direction to the tension acting on the inked ribbon portion by the take-up core (62).
