を生かしつつ多色記録を保ちたいという市場要求も強く
、多色記録を得るための技術が種々提案されている。The thermal transfer printer configured as described above makes it possible to print on large sheets of paper. However, conventional ink ribbons print in only one color, but there is a strong market demand for maintaining multicolor recording while taking advantage of the advantages of the above-mentioned thermal recording method, and various techniques for obtaining multicolor recording have been proposed. .
このような熱転写記録装置として、色調の異なる転写剤
を２層に形成し、発熱手段の発熱量を変化させ、転写剤
を表層の一層のみ、或いは２層共溶融させて２色の記録
を選択的に行なう構造のものが提案された。In such a thermal transfer recording device, two layers of transfer agents with different tones are formed, the amount of heat generated by the heat generating means is changed, and two-color recording is selected by melting only one layer of the transfer agent on the surface layer or co-melting the two layers. A structure was proposed that would allow this to be done.

に転写し、２色記録を得るという、２色型熱記録要素が
開示されている。For example, in JP-A No. 5 El-148591, two heat-melting high melting point ink layers A and a low melting point ink layer B containing π different coloring amounts are sequentially laminated on a support from the base material side. . In the case of low heat applied Nelky, only the low melting point ink layer B is transferred onto the plain paper, and in the case of high heat applied energy, the heat melt ink layer A? A two-color thermal recording element is disclosed in which both A and B are transferred to obtain a two-color record.
しかし、この方法ではＡ層とＢ層の融点差が小さい場合

らず、保存性の低下及び地汚れ発生の原因となり、印字
品位のよい２色記録は望めないという欠点を有する。However, in this method, if the difference in melting point between layers A and B is small, the same material is used for layers A and B, so it is a national problem to separate the two layers, and it is difficult to separate layers A and B. If the melting point difference is increased in order to achieve a good transferability of the entire ink layer, the melting point of the B layer must be reduced considerably, which may cause a decrease in storage stability and the occurrence of scumming. , has the disadvantage that two-color recording with good print quality cannot be expected.

点がある。However, in this method, each ink layer is made of a different type of material.
This method is considered to have better color separation than the former method, but as it requires the use of low melting point materials, it is difficult to avoid background stains and poor storage stability. In addition, a common problem with both is that two-color recording cannot be performed unless the applied energy is changed, and controlling the applied energy of the print head requires not only electrical circuit hardware but also software processing, making control difficult. The disadvantage is that it is complicated.
もちろん、２色以上の多色になれば制御は更に困難にな
る。Of course, if there are more than two colors, control becomes even more difficult.
そこで、次のような構造のものが提案された。Therefore, the following structure was proposed.

術である。That is, in order to provide clear two-color recording on recording paper, a first heat-melting ink layer and a second heat-melting ink layer having mutually different tones are provided on a support in order from the support side,
After the heat-melting second ink layer is brought into contact with a recording medium and thermal energy is applied from the support side, when the support is peeled from the recording medium, the thermal energy is applied and then the support is removed. This is a technique for selectively forming two-color recorded images on a recording medium by changing the time until peeling.

This is a schematic drawing in the thickness direction of the thermal transfer material showing the outline of the case where the second ink layer 23 is transferred together. FIG. 6 shows the state before recording. The difference from the case shown in FIG. 4 is that the thermal transfer material 19 is After being heated, the recording paper 2 and the thermal transfer material 19 remain in close contact for a certain distance J.
The point is that a guide member 24 is provided for peeling off the thermal head after the thermal head moves in that state. The time from when thermal energy is applied to the thermal transfer material 19 by the pressing member 24 until the thermal transfer material 19 is peeled off becomes longer.

This shows a state in which the transfer material 19 is peeled off from the recording paper 2, both the first ink layer 22 and the second ink layer 23 are transferred, and a black mark m 22 a is obtained on the recording paper 2.

写材と被記録体との剥離タイミングを変えることにより
、鮮明な２色の印字が得られるものである。Based on the above principle, clear two-color printing can be achieved by using a thermal transfer material with overlapping ink layers that are difficult to mix (easily separated) when heat is applied, and by changing the timing of peeling the thermal transfer material and the recording medium. It is something that can be done.
次に、具体的な実施例について説明する。Next, specific examples will be described.
本発明が採用した方法は、熱転写材を記録紙から剥離す

変化させることによって決定しようとする方法である。The method adopted by the present invention is a method in which the timing at which the thermal transfer material is peeled off from the recording paper is determined by changing the speed of movement of the thermal head in the lateral direction.

ものである。In other words, when only the second ink layer is transferred to the recording paper, the moving speed of the thermal head is increased to peel off the thermal transfer material from the recording paper immediately after applying thermal energy to the thermal transfer material, and the first ink layer When both the second ink layer is transferred onto the recording paper, the movement speed of the thermal head is controlled to be slow in order to separate the thermal transfer material from the recording paper after a certain period of time after applying thermal energy to the thermal transfer material.

発生しにくいためである。This is because when the heater part 17b is located near the left end of the thermal line as shown in FIG.
The distance from to the 2116 position of the support becomes small,
This is because temporal differences are unlikely to occur due to changes in the moving speed of the thermal radar 17.

By shifting the distance in the width direction, it is possible to generate a clear difference in the length of the peeling time with respect to the speed change.

４の回転速度により決定される。FIG. 2 shows a timing chart showing the timing of applying thermal energy to the thermal transfer material 19 by the heater portion 17b and the timing of peeling the thermal transfer material from the recording paper. That is, the time T from the time of application of thermal energy until the peeling of the support is determined by the moving speed of the thermal heater. The thermal head 17 is provided on a carriage 7, and the speed of the carriage 7 is controlled by a shift pulse motor 1 via a timing belt 9.
It is determined by the rotation speed of 4.

るように制御する。Therefore, when the operator specifies whether to transfer only the second ink layer of the thermal transfer material 19 or both the first ink layer 22 and the second ink layer 23 using input means such as a keyboard (not shown), the shift pulse motor 14 control so that the rotation speed of the

モータ１４の回転速度を遅くしてやればよい。That is, in the case of transferring only the second ink layer 23, the rotation speed of the one-digit feed pulse motor 14 is increased to shorten the time T, and the first ink layer 22. If the second ink layer 23 is to be transferred together, the rotational speed of the shift pulse motor 14 may be slowed down to increase the time T.

低く設定させる必要がある。On the other hand, in order to keep the applied heating energy constant and maintain uniform recording quality, when the time T is short, the voltage supplied to the thermal head 17 and the heater part 17b is increased, and when the time T is long, the voltage supplied to the heater part 17b is increased. It is necessary to set the supply voltage to 17b low.

について２組のテーブルを予め設定記憶させておく。To do this, a central processing device (not shown) that controls the thermal transfer printer 1 is required to transfer only the second ink layer 23 and to transfer both the first ink layer 22 and the second ink layer 23. Two sets of tables are preset and stored in a ROM (read-only memory) for each of the pulse rate of the shift pulse motor 13 and the voltage applied to the heater part 17b of the thermal head 17.

大させることができる。[Effects] As is clear from the above description, according to the present invention, there is a means for changing the timing of peeling between the transfer material and the recording medium using a thermal transfer material in which ink layers that are difficult to mix with each other are superimposed when heat is applied. Since the present invention adopts a configuration in which the moving speed of the thermal head that applies heat is changed, a clear two-color recorded image can always be obtained with a simple configuration without the need for a separate special mechanism. Furthermore, since the heating element of the thermal head is provided closer to the rear in the running direction of the thermal transfer material, the above-mentioned effects can be further enhanced.
