<p>PURPOSE:To allow lead wires to be arranged easily and to reduce differences among the exothermic values on each resistance portions by a method wherein distances between the exothermic resistance portions of a thermal head with one line width and common connecting wires are shortened and the arrangement density is reduced. CONSTITUTION:To take an example, if in one line, N=1728 dots and in exothermic resistance elements of an adjacent group, l=m+n=54+54=108 dots, the 1st main group common connecting wires 11-116 connecting odd m=54 exothermic resistance portions (R1, R3, ..., R107), ...(R1621, R1623...R1727) and the 3rd main group common connecting wires 31-316 connecting odd n=54 exothermic resistance portion (R2, R4, ...R108), ...(R1622, R1624, ...R1728) are arranged in opposite sides to each other referring to the exothermic resistance elements R1-R1728 and therefore, the common connecting wires of the 2nd and the 4th main group 21-254 and 41- 454 also are arranged in opposite sides to each other.</p> |
