印字できるようにしたものであった。(Prior Art) A thermal transfer ink ribbon, which has been considered as a thermal recording medium, has a wax-based thermal ink ribbon on one side of a base material 11 made of polyester film, capacitor paper, etc., as shown in FIG. It is constructed by providing a fusible ink layer 12, and when used, the heat-fusible ink layer 12
The heat generating head I3 is applied to the base material 11 from the side opposite to the surface on which the heat generating head 13 is formed, and by opening and closing the current flowing through the heat generating head 13, the heat generating head 13 is heated and cooled, and when the head 13 generates heat, the heat is transferred to the base material. 11 to heat the desired portion of the heat-melting ink layer 12, melting the ink and applying heat to the base material 11.
It is transferred onto the transfer paper 4 by peeling it off, and
When the head 13 is cooled, the ink remains attached to the base material 11 and is not transferred onto the transfer paper, so that a desired pattern can be printed.

あった。In this way, the conventional thermal transfer ink ribbon 10 has a base material 1
Since the ink is heated through the base material 11, there is an energy loss, and the heat from the throat 13 is not transmitted only in the thickness direction of the base material 11, but is also dispersed in the length and width directions of the base material 11. However, since the ink in the area to be transferred and the surrounding ink are also melted and transferred, the printing becomes blurred and high-definition printing cannot be achieved.
そこで、第５図に示すように、ポリカーボネートにカー

熱溶融性インク層２２を設けた通電転写形インクリボン
２０が提案されている（例えば米国特許第４，１０３，
０６６号明細Ｗ）。Therefore, as shown in FIG. 5, an electrical transfer type ink ribbon 20 has been proposed in which a wax-based heat-melting ink layer 22 is provided on a base material 21 made of polycarbonate mixed with carbon to form a high resistance material ( For example, U.S. Patent No. 4,103,
No. 066 Specification W).

。When using this current transfer type ink ribbon 20, as shown in FIG.
The electricity from the power supply 7 is applied to the ink ribbon 20 from the energizing electrode 5, and the electrical resistance of the base material 21 causes the base material 21 to
Printing is performed by generating local heat, melting the ink with the generated heat, and transferring the melted ink to the transfer target IE 4. The electricity passed through the ink ribbon 20 is passed through the base material 21 and collected. It returns to the power electrode 6.

印字の精細度が若干低下するという問題があった。Although such an electric transfer type ink ribbon 20 has less energy loss and can obtain high-definition printing than the conventional thermal transfer type ink ribbon 10, the base material 21 is not limited to its thickness direction. , because it has electrical resistance in the length and width directions, the electricity passed through it is dispersed, resulting in energy loss, or the ink surrounding the desired area is heated by the dispersed current.
There was a problem in that the definition of printing was slightly reduced.

。As mentioned above, a base material that has high electrical resistance in the thickness direction and electrical insulation resistance in the length and width directions is a resin film with excellent heat resistance, such as a polycarbonate film, and is made of fine particles in the thickness direction. A large number of pores are formed, and the pores are filled with fine carbon black, aluminum, silver,
It is manufactured by filling a fine powder of gold powder such as copper or brass to form a conductive path only in the thickness direction.

字が得られる。The operation of the current transfer type ink ribbon having a base material with a specific structure as described above will be explained with reference to drawings as necessary.
When using the above-mentioned current transfer type ink ribbon l,
As shown in FIG. 2, the current-carrying electrode 5 is applied to the side of the base material 2 on which the ink layer 3 is not formed, and on the other hand, it is brought into contact with the feeding side part of the heat-melting ink layer 3 over a wide area. A current collecting electrode 6 such as the above is applied, and in this state, two electrodes 5.
Apply voltage across 6 to energize. Under such circumstances,
The current flows through the current-carrying electrode 5 - the base material 2 - the ink layer 3 - the current collecting electrode 6, and heat is generated in the base material 2 which has a resistance value that allows it to pass through, and this heat is transmitted to the ink layer 3. , the ink is melted and transferred onto the transfer paper 4. In this way, in the case of the current transfer type ink ribbon 1, since the conductive path is formed only in the thickness direction of the base material 2, the energy loss is much less than that of the conventional thermal transfer type ink ribbon 10. There is less energy loss compared to the proposed current transfer type ink ribbon 20, and unlike the proposed current transfer type ink ribbon 20, the ink near the printing area is heated by the heat generated by the dispersed current, making the print blurry. Therefore, in terms of printing, it is possible to obtain printing with higher definition than not only compared to the conventional thermal transfer type ink ribbon 10 but also compared to the proposed electric transfer type ink ribbon 20.

精細度の高い印字が得られる。As explained above, in the present invention, since heat is generated in the base material 2, there is less energy dissipation, and it is possible to heat the ink in a desired area with less energy than in conventional thermal transfer ink ribbons. Further, since the conductive path of the base material 2 is provided only in the thickness direction, and the base material 2 is made of an insulator in the length direction and width direction, energy loss is extremely small. Also,
Unlike the proposed current transfer type ink ribbon 20, the ink near the print area is not heated by the heat generated by the dispersed current, so the print is less likely to become blurry, and is even better than the conventional thermal transfer type ink ribbon 10. Even compared to the proposed electrical transfer type ink ribbon 20, printing with higher definition can be obtained.
