PURPOSE:To improve the quality of print by a thermal head by arranging electrodes in such a manner that they transverse beltlike thermal resistors obliquely. CONSTITUTION:Common electrodes 3 and discrete electrodes 4, both made of gold, are arranged alternately in such a manner that they transverse the belt-like resistors 1, 2 of a thermal head obliquely. Therefore, if the irregularity of resistance value of each thermal element is significant, the unevenness of printing density does not generate so much and high-quality printing is assured. |
