PURPOSE:To form a thermal head of lesser voltage loss by using a wider width of a recording current-earth conductor. CONSTITUTION:A conductor SP' for supplying image signals is set between a recording current earth conductor PG and connecting terminals T1-Tm' to IC. A recording current earth terminal TG' of IC for receiving image signals is set through an image signal input conductor SP' on the opposite side of the connecting terminals T1-Tm' to IC. In the case of the thermal head of 12 numbers/mm. for example, the width of the recording current earth conductor can be set to about 0.6mm.. Because of small conductor resistances, the variation in the loss of print recording voltage can be lessened, and a thermal head of lesser print unevenness can be formed. |
