つ基板の中から、はぼ同じ抵抗値のものを2枚(または
3枚以上)組み合わせてヘッドを構成していた。When constructing a thermal head, a method of combining two (or three or more) substrates is often used. However, the average resistance value of the resistor on the substrate varies greatly from substrate to substrate due to process reasons. Conventionally, a head has been constructed by combining two (or three or more) substrates having approximately the same resistance value from among substrates having various average resistance values.
したがって、工数が多くかかり、ヘッドの原価低減を妨
げるという欠点があった。Therefore, there is a drawback that it requires a large number of man-hours and prevents a reduction in the cost of the head.

ことにある。An object of the present invention is to provide a reduction in the number of steps for assembling head substrates by eliminating the need to match the average resistance values of two (or three or more) substrates on a thermal head.

抵抗値を一致させる必要が全くなくなった。(Summary of the invention) When a thermal head is configured with two (or three or more) substrates, the resistance of each substrate can be reduced by independently controlling the pulse duty of the printing strobe signal for each substrate. There is no longer any need to match the average resistance value of the body.

In FIG. 1, a thermal head 1 is equipped with a monitor resistor 2 that shows the average resistance value of the left half board 4 and a monitor resistor 3 that shows the average resistance value of the right half board 5. (Resistance) The left half duty adjustment circuit 7 and the right half duty adjustment circuit 8 read the average resistance value of each half board. Next, the CPU 6 independently determines the duty of the printing strobe signal (ratio of printing time to total time) for the two half boards,
A print strobe signal (with different duties) is sent from the left half duty adjustment circuit 7 to the driver IC 1o on the left half board 4, and from the right half duty adjustment circuit 8 to the driver IC 11 on the right half board 5. However, the left half board 4 and the right half board -
Even if the average resistance values of the seven substrates 5 are different, the same energy can be supplied to the resistor.
