PURPOSE:To enhance printing capacity and to attain to facilitate gradation recording, by providing another one lead electrode group led out from a printing resistor in the direction opposite to led-out lead electrode groups. CONSTITUTION:A printing resistor 3 formed in a strip shape is formed widely and the printing resistor sides of lead electrode groups a1-an led out to one side are respectively formed in a length over the entire lateral direction of the printing resistor 3 while the printing resistor sides of lead electrode groups b1-bn led out to the other side are respectively positioned so as to reach the central part of the printing resistor 3 in the lateral direction thereof. Other one lead electrode groups c1-cn led out from the printing resistor 3 to the opposite direction are formed at positions opposed to the lateral direction of the lead electrode groups b1-bn and the printing resistor 3. Then, the printing resistor 3 between the predetermined electrode of the lead electrode groups a1-an and the adjacent predetermined electrode of the lead electrode groups b1-bn or that of the lead electrode groups c1-cn is allowed to generate heat. By this method, the quantity corresponding to two lines can be simultaneously recorded. |
