There was a problem that a print could not be obtained.
上記問題は第3図に示すがごとく加熱溶融したインク3
1が被転写物12の凹部32で接触しない為ドツト抜け
が生じることが主因である。The above problem is caused by heating and melting ink 3 as shown in Figure 3.
The main reason for this is that the dots 1 do not come into contact with the concave portion 32 of the transferred object 12, resulting in missing dots.
上記問題に対して記録ヘッドを弾性体にして被転写紙の
粗面に追従させるという考えがあるが、記録ヘッドには
耐熱性が必要なのでこの考えは温度負猜の少ない低速度
の印写装置にしか適用できない。To solve the above problem, there is an idea to make the recording head an elastic body and make it follow the rough surface of the transfer paper, but since the recording head needs to be heat resistant, this idea is not suitable for low-speed printing equipment with less heat stress. It can only be applied to

。[Embodiment] FIG. 1 is a diagram showing the structure of an electric thermal transfer printing device in an embodiment of the present invention. FIG. 1(a) shows the mechanism of the entire printing apparatus, and FIG. 1(b) shows an enlarged view of the area within the broken line 41 in FIG. 1(a). Reference numeral 12 denotes a transfer paper, and 13 is an electrically conductive thermal transfer film fed by a transfer paper supply roller 42, which is fed out by a film supply roller 43, undergoes a printing process, and then is wound up by a film take-up roller 44. 45
is a mechanism that applies tension to the electrically conductive thermal transfer film in the direction of arrow A. The structure of the electrically conductive thermal transfer film 12 includes a base layer 10 made of polyethylene terephthalate film (PET) with a thickness of 6 μm, a resistive layer 14 coated on one side of the base layer, and an ink layer 11 coated on the other.The resistive layer 14 is made of 20% by weight carbon. Powder is dispersed in resin. The resistance value is approximately 1 to 0
It was 7cm2. Further, the conveyance speed of the transfer paper, the electrically conductive thermal transfer film, and the lumen was approximately 57 mm/sec. This is 1

は約3mmである。48 is a suppressing mechanism for pressing the transfer blade 46 through the fulcrum 49 in the axial direction of the platen 47. The platen 47 is a back side holding member that holds the transfer paper 12, which is an object to be printed. The transfer blade 46 is shown in FIG. 1(b).
As shown in the figure, an elastic body 54 is bonded to the tip of a plate-shaped metal 53, and a plurality of hard particles 55 are bonded to the tip of the elastic body 54. Further, on the back surface near the tip of the metal plate 53, there is an electric heater 56 for heating the transfer blade 46 and a temperature sensor 57 for monitoring the temperature of the transfer blade.
There is a C installed. 58 is a fulcrum for stabilizing the path of the thermal transfer film. Reference numeral 21 denotes a current-carrying recording head consisting of a recording electrode 20 and its support 58. The recording frequency is 1
, 5 m5ec/1ine. Further, the distance from the contact point of the recording head 21 with the energized thermal transfer film 13 to the contact point of the transfer blade 46 with the energized thermal transfer film 13 is about 3 mm.

転写ブレード46によるインクの被転写紙への転写の工
程を転写過程と称す。At this time, since tension is applied in the direction of arrow A by the mechanism 45 for applying tension to the electrically conductive thermal transfer film, the resistance layer 14 of the electrically conductive thermal transfer film is strongly pressed against the recording electrode 20. Moreover, since the base layer of the electrically conductive thermal transfer film 13 is made of a polymer resin and has ductility, it can follow the etched portion 60 of the recording head without any problem even if the linearity is somewhat poor. Therefore, good current conduction is possible between the -C recording voltage W&20 and the resistance layer 14, and of course it does not depend on the surface condition of the transfer paper 120 at all. In this manner, the selected portion 61 of the ink layer 11 is heated and melted by the heat generated by the electric current in the resistance layer 14 . Hereinafter, the process of heating and melting the ink by the recording pad 21 will be referred to as the heating process, and the process of transferring the ink to the transfer paper by the transfer blade 46, which will be described later, will be referred to as the transfer process.
上記工程により加熱溶融されたインクは本発明による加
圧転写機構により被転写紙に転写される。The ink heated and melted in the above steps is transferred onto the transfer paper by the pressure transfer mechanism according to the present invention.

御した。3000以下であると加熱時に溶融したインク
の粘度が高くなり転写が不安定となり、又60°C以上
となると加熱時に溶融されなかったインクの粘度が下が
り字汚れの原因となる。The transport time of the ink from the heating process to the transfer process is about 50 m5ec, so even if it is cooled by the atmosphere, it still maintains a molten viscosity that allows transfer, and by applying pressure with the transfer blade 46, it is transferred to the paper to be transferred. Transfer becomes possible. However, if the room temperature fluctuates, the temperature of the ink during transfer also changes and the optimum viscosity for transfer cannot be stably maintained, so the ink is appropriately heated through the transfer blade 46 by an electric heater 56 and a temperature sensor 57 on the back of the transfer blade. . In this example, the temperature of the ink during the transfer process was controlled to be 30 to 60°C with respect to room temperature fluctuations of -5 to 45°C. If it is less than 3000, the viscosity of the ink melted during heating becomes high and transfer becomes unstable, and if it exceeds 60° C., the viscosity of the ink that is not melted during heating causes sagging marks.

と被転写紙12の間の通電熱転写フィルムは省略した。At the tip of the transfer blade 46, an elastic body 54 is connected to a metal body 5.
It is glued to 3. Furthermore, a plurality of hard particles 55 are embedded in the end face of the elastic body 54. By adopting such a structure, it becomes possible to contact and press the ink 11 of the electrically conductive thermal transfer film also against the recessed portions 33 of the transfer paper. Although the effect can be obtained even if the tip of the transfer blade has a structure consisting only of an elastic body, it becomes even more effective by embedding hard particles in the end surface. The reason for this will be explained using Figure 2. 54 is an elastic body, and 12 is a cross section of the rough surface of the transfer paper. 55 is a hard particle. In addition, the elastic body 54
The electrically conductive thermal transfer film between the paper 12 and the transfer paper 12 was omitted.

上の物を用いるとより効果が増した。When applying pressure to the uneven surface of the transfer paper 12 using only an elastic body as shown in FIG. As a result, the recess 33 cannot be pressurized. So the second
As shown in FIGS. (b) and (c), if hard particles 55 are embedded in the surface of the elastic body 54, the amount of deformation of the elastic body to follow the same unevenness gap can be reduced. Furthermore, as in this embodiment, since the elastic body moves while applying pressure to the transfer paper in the direction of arrow B, there is a certain probability that the recesses 34 that could not be pressed in FIG. It becomes possible to apply pressure as shown in (C). In addition, wear resistance is also improved by embedding hard particles. In this embodiment, the elastic body 54 is made of acrylonitrile butadiene rubber (NBR), the hard particles 55 are made of alumina particles with a coarse diameter of 30 to 100 μm, and NBR is used as the elastic body 54.
When molding BR, the alumina particles were mixed on the surface. By the way, the width of the concave portion of transfer paper (for example, pound paper) having a Bekk smoothness of 10 seconds or less is 50 to 200 μm, the depth is about 50 μm, and the distribution thereof is wide. Therefore, it was more effective to mix the rough type of hard particles 55 with a variety of branch yarns of 50 to 200 μm. The arrangement density of the hard particles 55 may be such that the hard particles do not come into contact with each other. In addition, the platen 47, which serves as a lower basin when pressure transfer is performed with a transfer blade, is preferably hard in order to apply pressure efficiently. In this example, the effect was further enhanced by using NBR with a hardness of 50 degrees or more.

35%も向上した。When we actually attempted printing using the configuration of the present invention described above, we found that while conventional printing was only possible on thermal transfer paper with a Beck smoothness of 200 seconds or more, it was also possible to print on bond paper with a Beck smoothness of 8 seconds. Good printing was possible. Furthermore, when the configuration of the present invention is used, the ink does not come into contact with the transfer paper during the heating process, so the heat does not escape to the transfer paper, so the printing efficiency is improved. When the transfer paper and the electrical thermal transfer film were heated in a polymerized state, the printing energy was 7 mJ per millimeter squared, but in this example, it was 4.5 mJ. Printing efficiency has improved by approximately 35%.
尚本実施例では通電熱転写記録方式の添って説明したが

Since the mechanism is such that the material to be printed and the film-like recording medium are sandwiched and pressurized, the heated and melted ink can be brought into good contact even with the paper having a rough surface. It is also effective in obtaining good prints on objects to be transferred.

幅な向上が得られる。従って熱転写方式の場合には従来

ーマルヘッドの蓄熱量も少なく高速印写が可能となる。Furthermore, since the ink and the object to be transferred are not brought into contact during the heating process, the applied heat does not diffuse to the object to be transferred, resulting in a significant improvement in printing efficiency. Therefore, in the case of the thermal transfer method, the temperature rise of the heating element is lower than that of the conventional method, so the amount of heat stored in the thermal head is small, and high-speed printing is possible.

ある。Furthermore, since the temperature load on the heating element is also reduced, the durability of the heating element and, in turn, the durability of the thermal head is improved. Also, in the case of the energized thermal transfer method, the thermal load and electrical load on the recording electrodes are similarly reduced, and the durability of the energized recording head is improved. In addition, both types have the effect of reducing the load on the power supply of the device and the height of the drive circuit, thereby reducing the manufacturing cost.
