PURPOSE:To obtain good printing quality to recording paper inferior in smoothness, by setting the distance from the terminal of the heat generating resistor element of each row to the end edge of the end or notch of a heat dissipating plate to a specific length or less. CONSTITUTION:Each of distances 9a, 9b from the terminals of the heat generating resistor elements 6 of both rows to the release ends 17a, 17b of a heat dissipating plate 1 is set to 2mm or less. A part 16b, where solid ink 13 is melted under heating by the rear heat generating resistor row 5b, reaches the release end 17b of the heat dissipating plate 1 within a short time and the molten part 16a of the solid ink heated by the front heat generating resistor row 5a is separated from an ink ribbon 11 by the ink ribbon peeling roller 19 arranged to the part of the notch 18 on the heat dissipating plate 1. The heat generating resistor rows 5a, 5b are positioned in the vicinity of the release ends 17a, 17b of the heat dissipating plate 1 and, after the solid ink 13 is melted under heating, the ink ribbon 11 can be released from recording paper 14 by each peeling means before said ink is solidified. therefore, high-quality recording can be applied to low smoothness paper. |
