THERMAL HEAD AND MANUFACTURE THEREOF

摘要

PURPOSE:To reduce blank run generated during the printing by making the width of heat generating resistor sections divided into several areas with a groove extending in the direction of facing electrode conductors larger than at least one of the electrode. CONSTITUTION:Electrode conductors 2A-2D are formed on an insulative substrate 1 and a belt-shaped resistor 5 is formed partly covering them to make heat generating resistor sections 7A and 7B by forming a groove 6. The heat generating resistor sections 7A and 7B are made larger in the width than that of the electrode conductors 2A, 2B, 2C and 2D and arranged at the position very close to each other through the groove 6 thereby reducing blank run generated during the thermal printing.
