。Conventionally, in this type of thermal transfer recording device, the pressing force between the thermal head and the platen is as high as about 20 seams, and aluminum profiles or the like have been used in consideration of the heat dissipation characteristics of the thermal head. Very thin condenser paper or polyester film is used as the base material of the ink film, and ink is applied to the surface and used as an ink film for thermal transfer.
ところが、インクフィルムが極く薄いものであるから、
サーマルヘッドとプラテンとの圧接力に不均一な部分が

た文字や図形に濃度差を生じるという欠点があった。However, since the ink film is extremely thin,
If there are uneven pressure points between the thermal head and the platen, there are drawbacks such as wrinkles in the ink film and density differences in transferred characters and figures.
本発明はプラテンとサーマルヘッドとの圧接力を均一に
保つことにより上記欠点を除去し、良好な転写記録が行
なえる熱転写記録装置を提供するものである。The present invention eliminates the above-mentioned drawbacks by maintaining uniform pressure contact between the platen and the thermal head, and provides a thermal transfer recording device that can perform good transfer recording.

ルヘッド保持機構4,6.9を設けたものである。The present invention provides a thermal transfer recording apparatus that includes a thermal head 1 whose heating element selectively generates heat according to recording information, and a platen roller 2 that presses a recording paper 11 and an ink film 10 against the thermal head 1. A thermal head holding mechanism 4, 6.9 is provided which swingably presses the central portion of the thermal head 1 so that the thermal head 1 is bent along with the platen roller 2 deformed by force.

Further, a spring 9 presses the thermal head 1 against the platen roller 2 via the paper 11 and the ink film 10.
will be established. 12 and 13 are rotation bearings for the platen roller 2, and 14 is a pulley.

The bending rigidity of the base 4 is set so that (z"-2A'Hc"AH") - υ (4EIH Engineering H: Moment of inertia when the thermal head and base are combined, lH 2 base length) If set, even if the platen roller 2 is deflected due to the pressure contact force, the thermal head 1 will also be deflected accordingly, so that a uniform pressure contact force can be obtained over the entire length.Furthermore, the base 4 can swing around the rotating shaft 3. Even if the assembly accuracy is poor and the left and right parallelism is slightly different, or even if narrow paper is set on one side, the pressure on the left and right sides will be kept uniform, so the ink film Transfer recording without density differences can be performed without wrinkles occurring on the lO.

いという効果がある。As explained above, the present invention prevents wrinkles on the ink film during transfer recording by holding the thermal head so as to flex along with the deformed shifter Latin roller due to pressure contact force and maintaining uniform pressure contact force. It has the effect of not causing any concentration difference.
