本発明は、熱転写記録装置に関し、特にサーマルヘッド
とインクフィルムとの電位的構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a thermal transfer recording device, and particularly to the potential structure of a thermal head and an ink film.
従来、この種の感熱記録装置に使用されるインクフィル
ムの基材にはポリエステルフィルムが用いられていたが
、ポリエステルフィルムは圧接摩擦により強く帯電する
性質があり、一方、サーマルヘッドも表面を発熱体保護
用の薄いガラス層で覆っているため、圧接摩擦により強
く帯電する性質がある。Conventionally, polyester film has been used as the base material for ink film used in this type of thermal recording device, but polyester film has the property of being strongly charged due to pressure friction.On the other hand, thermal heads also have a surface that protects the heating element. Because it is covered with a thin glass layer, it has the property of becoming strongly charged due to pressure friction.

、蓄積された電荷が発熱素子に放電されて前記サーマル
ヘッドが破壊され、記録不能となるという欠点があった
。Therefore, when the device enters the recording state, the surface of the thermal head is charged to a high potential due to pressure friction with the ink film, and the accumulated charge is discharged to the heating element, destroying the thermal head and making it impossible to record. There were drawbacks.
本発明は、サーマルヘッドとインクフィルムとが圧接摩
擦してもサーマルヘッドの表面に電荷が蓄積しないよう

可能とする熱転写記録装置を提供するものである。The present invention provides a thermal transfer recording device that solves the above-mentioned drawbacks and enables good recording at all times by preventing charge from accumulating on the surface of the thermal head even when the thermal head and the ink film come into contact and rub against each other. It is.

のクランドＥに接地したものである。The present invention is a thermal transfer recording device that transfers ink onto a recording medium 2 by selectively energizing a heating element 4-2 to generate heat according to recorded information. An ink film 1 made up of
and are electrically grounded to a common ground E with the heating element 4-2 of the thermal head.
インクフィルム１、軸５．６をサーマルヘッドの発熱体
４−２と電気的に共通のグランドＥに接地することによ

is guided by guide shafts 5 and 6 and pressed against a thermal head 4 by a platen lawn 3 via a recording medium 2. A heating element 4-2 is formed at the contact portion of the thermal head 4 with the platen roller 3, and a protective glass layer 4 is formed.
-1 covers the surface. Guide shaft 5.6 and heating element 4

なく、常に良好な熱転写記録が可能となる。In the thermal transfer recording device using the ink film 1 configured as described above, even if the platen roller 3 rotates and drives the recording medium 2 and the ink film 1 forward while pressing against the thermal head 4, the surface of the glass layer does not reach the surface of the glass layer. Static electricity generated by friction is removed by the highly conductive material 1-3 and the guide shaft 5.
, 6, and flows to the ground that is commonly grounded with the heating element 4-2, so that the heating element 4-2 of the thermal head 4 is not destroyed by the discharge of the accumulated charge, and is constantly Good thermal transfer recording becomes possible.
