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 head (1) is pressed against a platen (62;12) consisting of rubber through a recording paper (13) or a heat sensitive paper. The thermal head (1) is provided a head base (2), a glaze layer portion (3a, 3b, 3c, 3d, 3a', 3d') mounted on the head base (2), and a heating resistor portion (4a, 4b, 4a', 4b') provided on the glaze layer portion (3a, 3b, 3c, 3d, 3a', 3d'). An unit area surface pressure (P) applied from the glaze layer portion (3a, 3b, 3c, 3d, 3a', 3d',) of the thermal head (1) to the recording paper (13) or the heat sensitive paper is set to not less than 0.3 kg/mm 2. A hardness (Hs) of the rubber of the platen (62;12) is adapted of about Hs 40°-Hs 100°. The high areas (13a) of the surface of the recording paper (13) or the heat sensitive paper are flattened to increase the smoothness of the surface of the recording paper (13) or the heat sensitive paper. A high quality printed product of the thermal transfer printer or the thermal printer can be obtained even when the relatively rough recording paper (13) or the heat sensitive paper is used as the object paper.

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： in the thermal transfer priner in printing with the ink ribbon (4) in plural columns, a center of a flat portion (1a) being formed on the platen roller (1) of a contact portion of the thermal head (3) and a center of the thermal head (3) are shifted corresponding to an amount (A x) of shift of printing position as against a center of width (R) of the ink ribbon (4). When the printing position is set above as against the center of width (R) of the ink ribbon (4), the center of the thermal head (3), is set above width (P) of the flat portion (1a) being formed on the platen roller (1) of the contact portion of the thermal head (3). When the printing position is set below as against the center of width (R) of the ink ribbon (4), the center of the thermal head (3) is set below width (P) of the flat portion (1a) being formed on the platen roller (1) of the contact portion of the thermal head (3). The present invention can prevent the shifting-up or the shifting-down of the ink ribbon (4) at the thermal head (3) in structure in which the center of the ink ribbon width (R) and the center of the printing shift in the plural columns printing.

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).
