などが提案されている。Conventional technology Conventionally, a method of printing and recording using thermal transfer (1) A thermal head is used as the print head, and printing pressure is applied to the head from the opposite side of the ink layer on the ink film coated with low melting point ink to conduct heat. A method of melting and transferring ink (Japanese Patent Application Laid-Open No. 53-84735) (2) Applying an electric signal corresponding to the image from a needle electrode and passing electricity through the support of the printing recording medium into the ink layer to detect the generation of electricity at that time. This is a method in which the ink layer is thermally melted and transferred using heat, and the ink support that is placed on the print recording medium uses a ribbon made of resin with metal powder dispersed therein, or one made of a high-resistance conductive film. Method, (Journal of the Intuition 7δ Child Society 1982. Vo1.11 Nα1, Proceedings of the 12th National Conference of the Institute of Image Electronics Engineers, 17) (3) A print recording medium is constructed by providing a heat generating layer and a return electrode on an ink support of medium resistance. A current path is set in the ink support using a needle electrode to generate heat, and the ink layer is thermally melted and transferred.
(4) A return electrode is provided on the same side as the needle electrode, and an electric signal corresponding to the image is applied from the needle electrode to form a current path to the return electrode in the heat generating layer of the print recording medium. A method has been proposed in which the ink layer is melted by heat generation in one thermal layer and then transferred.

Since the energy that can be transmitted is small, there are large restrictions on ink materials and poor transfer control (dot modulation is not possible and wax-based materials are the main components). ), ■ The electrical conductivity loss of the support is large and the mechanical strength is poor, ■ The dot accuracy of printing is low, and ■ The electrical anisotropy is insufficient, so that 1. The method (3) has the drawbacks of nok generation and large energy loss; and method (3): ■ There is no conductive anisotropy in the ink support, so the dots spread; ■ There is a large amount of leakage current that does not contribute to heat generation; There are disadvantages such as poor energy efficiency, ■The ink support must have resistance, so the contact resistance between the &1 electrode and the ink support is large.Furthermore, in method (4), the applied current is Due to the current path to one house, it passes through the heat generating layer twice, resulting in twice the energy loss.Also, since the sliding contact is made twice with the needle electrode and the return electrode, the heat loss due to contact resistance is also doubled. arise.

ク層９として転写される。A heating element layer 2 and a return electrode layer 3 each have a needle-like electrode 6 for printing, a heating element layer 2 having a fine isolated pattern 1 made of conductive ceramic on its surface.
, is brought into pressure contact with a print recording medium consisting of an ink release layer 4 and a heat-melting ink layer 5, and is moved at 1 g. In response to the electric signal from the printing needle-like electrode 6, a current flows from the minute isolated conductor pattern to the heating element layer, generates heat, melts the heat-melting ink layer in that area, and transfers it onto the elastic pressure contact member 8. It is transferred to the paper 7 as a transfer ink layer 9.

ージも減少するので寄合も延長する。In the present invention, energy is transmitted and recorded by the above-mentioned path, but in this case,
Since minute isolated patterns made of conductive ceramic are provided on the heat-melting ink layer, damage caused by heat generated at the contact point between the printing needle electrode and the print recording medium during printing and mechanical sliding scratches are avoided. This can be avoided due to the high heat resistance and hardness of ceramics. Therefore, changes in characteristics are small even when used many times at high speed. Further, due to the conductivity of the ceramic material, the contact resistance between the printing needle electrode and the printing recording medium is reduced, and the heat generation energy loss in the printing heating circuit is reduced, so that the energy efficiency per printing dot is increased. Furthermore, since damage to the surface of the print recording medium is also reduced, the amount of overlap is also extended.

A fine isolated pattern 1 made of conductive ceramic is provided on the surface. This minute isolated pattern may be one-hundredth or less of the volume resistivity of the heating element layer 9, and the area of the minute isolated pattern is four-fifths or less of the area of one pixel electrode of the signal application electrode. , preferably one-quarter or less.

発明の効果
本発明の印字記録媒体は、上記の基或を有するから次の
ような効果を生じる。Effects of the Invention Since the print recording medium of the present invention has the above-mentioned base, it produces the following effects.
１）高速印字が可能である。1) High-speed printing is possible.
導電性セラミックからなる微小孤立パターンは、耐熱性
を有するから、印字時の印字用針状電性と印字記録媒体
との接点分での発熱ダメージが回避でき、又、ヒートシ
ョックによる表面層の空気との化合を回避できるので、
多数回の印字発熱によっても印字記録媒体を基或する材
料の変質が生じない。したがって、高速で多数１使用し
ても特性の劣化が著しく少なくなる。したがってまた、
１ドツト当りのパルスエネルギーが大きく、しかも短パ
ルス幅化が可能であり、高速印字が可能になる。The minute isolated pattern made of conductive ceramic has heat resistance, so it can avoid heat damage at the point of contact between the printing needle conductor and the print recording medium during printing, and also prevent air in the surface layer from heat shock. Since it is possible to avoid combination with
The material on which the print recording medium is based does not change in quality even when heat is generated during printing many times. Therefore, even if a large number of devices are used at high speed, the deterioration of characteristics is significantly reduced. Therefore, also
The pulse energy per dot is large and the pulse width can be shortened, making high-speed printing possible.
２）印字エネルギー効率が高い。2) High printing energy efficiency.
印字用針状電極と印字記録媒体との接触抵抗が下がるた
め、印字発熱回路中の発熱エネルギーロスを減少させ、
発熱体層以外での発熱を抑止する。Since the contact resistance between the printing acicular electrode and the printing recording medium is reduced, the heat generation energy loss in the printing heating circuit is reduced.
Prevents heat generation in areas other than the heating element layer.
このため、印字のドツト当りのエネルギー効率が上がる
。即ち、従来の印字記録媒体のように発熱体層が直接印
加用針状電極に接するものでは、接した部分の抵抗値が

針電極への熱リークも大きいため、熱溶融性インクの溶
融に実際に使われるエネルギー効率が低下するばかりで
なく、最大発熱部から熱溶融性インク層までの距離も発
熱体層が最大発熱部であるものに比べて大きく相違する
ため、熱伝導的見地からも効率が悪い。Therefore, the energy efficiency per printing dot increases. In other words, in conventional print recording media where the heat generating layer is in direct contact with the needle electrode for applying voltage, if the resistance value of the contact area is large, the contact resistance becomes extremely large and heat generation occurs at the pressure contact point. The amount of heat generated there becomes large, and the heat leaked to the printing needle electrode is large, so not only does the efficiency of the energy actually used to melt the heat-melt ink decrease, but also the heat-melt Since the distance to the ink layer is also significantly different from that in which the heating element layer is the largest heat generating portion, efficiency is also poor from a thermal conduction standpoint.
ところが、本発明の印字記録媒体における導電性セラミ
ックからなる微小孤立パターンは、このような現象を生
じることがないから、エネルギー効率は、従来のものの
数十倍となる。However, since the minute isolated pattern made of conductive ceramic in the print recording medium of the present invention does not cause such a phenomenon, the energy efficiency is several tens of times higher than that of the conventional one.
３）印字記録媒体の寿命が延長する。3) The lifespan of print recording media is extended.
導電性セラミックからなる微小孤立パターンを設けたこ
とにより、印字用針状電極との接触抵抗が減少し、印字
記録媒体表面のダメージが無くなるので、常に一定の状
態を保持することができる。By providing a minute isolated pattern made of conductive ceramic, the contact resistance with the printing needle electrode is reduced and damage to the surface of the printing recording medium is eliminated, so that a constant state can be maintained at all times.
又、導電性セラミックは、金属のように放電や接触抵抗
による発熱などで酸化物の化合物を形成することがない
から、抵抗むら等、物理的性質の変化がない。したがっ
て、寿命が著しく延びる。Furthermore, unlike metals, conductive ceramics do not form oxide compounds due to discharge or heat generation due to contact resistance, so there are no changes in physical properties such as resistance unevenness. Therefore, the lifespan is significantly extended.
４）高画質化を行うことができる。4) High image quality can be achieved.
本発明の印字記録媒体は、発熱体層と帰路電極層を設け

ことができる。Since the print recording medium of the present invention is provided with a heat generating layer and a return electrode layer, only the thermoplastic member is subject to restrictions in terms of materials. Therefore, one can freely select one that is good in terms of color, and there are no restrictions on electrical characteristics. Further, since the heat-melting ink layer is affected only by the heat generation of the heating element layer, the transfer responsiveness of the heat-melting ink layer is extremely poor. Therefore, a high-quality color image can be reproduced, and a robust image quality with high gradation can be recorded.
