    摘要: A main control unit (100) for controlling a dot printing element (1-17) in a laser beam printer has a first control means for controlling the dot printing element (1-17) so as to print a predetermined dot size in accordance with an existence of a dot signal in an image information signal. The main control unit (100) has a second control means and a control selection means (160). The second control means controls the dot printing element so as to vary a size of the dot of a dither matrix. The control selection means (160) operates selectively the first control means and the second control means. A gradation data is transmitted to the printer without conversion of a dither matrix data. The printer can print an image in response to in either cases of a character pattern dot data signal and a gradation data signal. The printer has a gradation signal on an interference, a gradation converting means (150) and a laser modulating means. The printer can connect in either cases of an existence state and a non-existence state of the gradation signal.

    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).
