Claims

[Scope of Claim for Utility Model Registration] A thermal printer device in which a printing paper and a thermal transfer member are placed one on top of the other, and a thermal head having a heat-generating portion is brought into contact with the paper from one side of the paper to thermally transfer print characters, figures, etc. In the above, a first thermal head is arranged such that the heat generating part is in contact with the upper surface side of the printing paper and the thermal transfer member arranged in an overlapping manner, and a first thermal head is arranged on the lower surface side of the printing paper and the thermal transfer member arranged in an overlapping manner. A second thermal head is provided with a heat generating section facing the heat generating section of the first thermal head, and a character/graphic pattern that is inverted is printed by the heat generating section of the first thermal head. A thermal printer apparatus comprising: a control section that controls printing using the heat generating section of the second thermal head.
