<p>PURPOSE:To embody a thermal printing head capable of substantially doubling printing density without bringing about the cost increase and scaling-up. CONSTITUTION:A first heating dot row R and a second heating dot row RE are parallelly arranged on a substrate so as to be shifted by a pitch 1/2 a dot pitch while the individual electrodes 5a, 5b electrically connected to the unit dots of the respective unit dots are connected in common and the common electrodes COMO, COME electrically connected to the respective heating dots are mutually set to separate systems and both of the first and second heating dot rows RO, RE can be driven by a common drive IC 7.</p> |
