  • Thermal line printer with plural thermal head substrates
    Patent number: 5367321
    Abstract: When composing a long thermal head by joining plural insulating substrates forming linear heating resistance element rows in the arranging direction, if the distance of the heating resistance elements at the remotest position of the insulating substrates is extended, a white stripe (white out) is formed at a position corresponding to the junction of the insulating substrates at the time of printing. In the invention, in the heating resistance element rows on the mutually adjacent insulating substrates, the heating resistance elements at the remotest position on each substrate are mutually jointed in a state of being deviated by 0.2 to 1.5 mm in the subscanning direction. Therefore, the height of the composition on the adjacent insulating substrate on an extended line of the heating resistance element rows on one insulating substrate is lower than the height of the heating resistance element rows on the same one insulating substrate.
