あつた。 Most conventional thermal printing devices print on thermal paper, which has drawbacks such as high paper cost and poor record retention. To improve this, some printers use a thermal ribbon coated with heat-melting ink to print on plain paper, but since thermal ribbons can only be used once, an endless film is used, and after printing, There is also a proposal to melt and apply heat-melting ink using a heating device and recycle it for use. However, the energy for melting and regeneration is greater than the energy used for direct printing.
There was a drawback that the equipment for regenerating melting became larger.

有する。 The operation of the above configuration will be explained. A drive signal is applied to the thermal printing head 3 from a control circuit (not shown), and a part of the strip member 1 is heated by the heat, and the heat-melting ink 12 on the outer surface is transferred to the recording paper 2.
transcribed into. After the transfer, the base 8 is moved one dot to the right along the guide shaft 9 by a drive mechanism (not shown). At this time, the contact pressure and relative speed between the replenishing members 6a, 6b and the strip member 1 are determined so that the strip member 1 and the recording paper 2 move relative to each other and the recording paper 2 is not soiled. In this manner, printing is performed on the recording paper 2 as the base 8 moves. When one line of printing is completed, the base 8 is moved away from the recording paper 2 by a mechanism not shown, and the strip member 1 returns to the left while being separated from the recording paper 2.
During this time, the recording paper 2 is fed by one line in preparation for printing the next line. Along with the above printing operation, the belt-shaped member 1 has been transferred with the heat-melting ink onto the recording paper 2.
As the base 8 moves, it is moved to a position facing the replenishing members 6a and 6b. The replenishing members 6a, 6b are rotated by driving members 7a, 7b at a circumferential speed different from the moving speed of the belt-like member 1 while being pressed into contact with the belt-like member 1. Therefore, a shearing force acts near the surfaces of the replenishing members 6a, 6b, and a portion of the hot melt ink near the surfaces of the replenishing members 6a, 6b moves and adheres to the outer surface of the strip member 1, thereby regenerating the ink. .
Furthermore, in order to obtain clear printing, it is necessary that the ink be applied uniformly, but in the present invention, as shown in FIG. Since the axes are inclined with respect to the traveling direction of the strip member 1 and the inclinations are different, there is an advantage that there are no streaks when applying ink to the strip member 1, and the ink can be applied uniformly.
本実施例のインクの再生に要するエネルギーを
加熱によつて再生するエネルギーと比較すると、
はるかに小さくてよいことがわかる。たとえば、
ベースフイルム１１の巾：w1＝６mm、厚さ：t1＝
12μｍ、比重：r1＝1.43ｇ／cm3、比熱：c1＝
2.2J／ｇ・degとし、熱溶融インク１２の巾：w2
＝６mm、厚さ：t2＝10μｍ、比重：r2＝1.1ｇ／
cm3、比熱：c2＝1.13J／ｇ・deg、また加熱温度Ｔ
＝100℃、１ドツト分の移動距離：ｌ＝0.35mmと
すると他に熱が逃げないとしても、
w1＝w1・t1・ｌ・r1・c1・Ｔ＋w2・t2・ｌ・
r2・c2・Ｔ
＝10.5mJ
が加熱のためのエネルギーとなる。 Comparing the energy required to regenerate the ink in this example with the energy required to regenerate it by heating,
It turns out that it is much smaller. for example,
Width of base film 11: w 1 = 6 mm, thickness: t 1 =
12μm, specific gravity: r 1 = 1.43g/cm 3 , specific heat: c 1 =
2.2J/g・deg, width of hot melt ink 12: w 2
= 6 mm, thickness: t 2 = 10 μm, specific gravity: r 2 = 1.1 g/
cm 3 , specific heat: c 2 = 1.13 J/g・deg, and heating temperature T
= 100℃, distance traveled for one dot: l = 0.35mm, even if no heat escapes elsewhere, w 1 = w 1・t 1・l・r 1・c 1・T+w 2・t 2・l・
r 2 · c 2 · T = 10.5 mJ is the energy for heating.
一方、本実施例による再生のためのエネルギー
は、たとえばＦ＝50ｇの力で、補充部材の周速度
を帯状部材の移動速度の３倍で矢印方向に回転さ
せたとすれば、帯状部材と補充部材の相対速度は
帯状部材の移動速度の２倍となり、１ドツト分の
再生にはl2＝2l＝0.7mmの移動を要する。したがつ
てその時のエネルギーは補充部材１個あたり
Ｆ・l2＝0.34mJ
本実施例では補充部材を２個使用しているか
ら、再生に要するエネルギーは
w2＝２×0.34
＝0.68mJ
となり、加熱溶融による再生エネルギー：w1＝
10.5mJにくらべはるかに小さいエネルギーでよ
い。 On the other hand, the energy for regeneration according to this embodiment is, for example, if the replenishment member is rotated in the direction of the arrow with a force of F=50g and the peripheral speed of the replenishment member is three times the moving speed of the belt-like member, the replenishment member and the replenishment member are The relative speed of is twice the moving speed of the strip member, and reproduction of one dot requires a movement of l 2 =2l=0.7 mm. Therefore, the energy at that time is F・l 2 = 0.34 mJ per replenishment member. Since two replenishment members are used in this example, the energy required for regeneration is w 2 = 2 × 0.34 = 0.68 mJ. Renewable energy by heating and melting: w 1 =
Much smaller energy is required compared to 10.5mJ.
以上述べたように本発明によれば、複数個の補

る。 As described above, according to the present invention, a plurality of replenishment members are provided, the rotational axes of which are inclined with respect to the traveling direction of the strip member, and the inclinations of the rotational axes are made different from each other. The belt-shaped member is moved relative to the belt-shaped member while being in pressurized contact, and a part of the replenishment member is moved and attached to the belt-shaped member by shearing force, so the ink on the belt-shaped member can be uniformly regenerated with less energy, and it is compact because no heating device is required. A thermal printing device with a simple structure can be provided and is very useful.
