Description

[Detailed description of the invention] [Technical field of invention,] The present invention relates to a thermal transfer type 0) printing device.

[J Detailed Description of the Invention and its Problems] A thermal transfer type printing device 1 is capable of printing a thermal transfer body by operating a thermal spatula with N thermal transfer bodies mounted on a transfer target. % of the ink applied: 'li: Insertion (a device that transfers; the more the surface of the object to be transferred is Higashi: When printing on plain paper with this device, the surface smoothness is low because the paper is composed of fibers, and a special 1 meter height was required.For this reason, printing on plain paper, such as -4 glass cards, is usually difficult. 1) It was used for printing, and there was a problem that the scope of use was narrow.

[Purpose of the invention]

Based on the above circumstances, the present invention has 7J-
The purpose of this is to enable good ink transfer even if the object to be transferred has low smoothness, thereby expanding the range of applications for image creation by thermal transfer. The purpose of the present invention is to provide a printing device that has the following features.

[Summary of the invention]

The present invention provides a method for smoothing the transfer target. f? By providing a means, the ink of the thermal transfer member is transferred to the supplied transfer object.
The smoothness of the body is set to IVIJ-5J.

[Practice of the Invention $+lLl Hereinafter, Book b6 ``') Illustrated is a drawing showing an example of J. In Fig. 11, 1 is paper Po as a transfer object) The base end is connected to the paper feeding mechanism 2, and the non-QHa part is connected to the trough 3 of the paper 11. Also, the loading path 1σ) is connected to the intermediate manufacturing part. From the paper feed mechanism 2 side, a smooth transfer mechanism 4, a first transfer mechanism 5, a second transfer mechanism 5, and a pressure mechanism 7 are arranged.

The above-mentioned paper feed +1 and paper feed 2 are arranged to be introduced one by one into the upper conveyance path by the paper trays 4 and 11M stored in the paper feed cassette 8.

The smoothing mechanism 4 presses and rolls the loading path 1 17
It is constructed by separating flat m-rollers 10, 10. Among these smooth rollers 10.10, the smooth roller 10 on the printing surface side of the paper P has a matte finish on its peripheral surface as shown in FIG. Also, the smooth roller 10 on the non-printing side of the paper P
(drill with a metal roller). And these smooth rollers 10
The paper P is pinched and conveyed by 1θ to make its surface smooth. In addition, flat steel roller 10

The first Su-Marchend 12 is made by using the smoothed paper P as a thermal transfer body and applying the transfer ribbon 1) of the funeral 1)! +ll1- by first transfer ribbon 1
IPt on paper P, '-! 4 It's better to do it. Note that 13 is a support roller that supports the non-printing portion of the paper P. The first rolled ribbon 1 is fed out from the first feeding reel 14, and passed between the first thermal head 12 and the conveying path 1 by a scale to the first winding reel 1.
Wind it up to 5" -] It's now 5. The first transfer ribbon 11 is made of, for example, a glass film or thin paper with a thick ink layer on one side, as shown in FIG. 3(a).

The second transfer h' mechanism 6 transfers the paper P that has passed through the tenth) transfer mechanism 5 to the winding drum 16 (411'y, 5,').

The ink of the 20th transfer head 17 is transferred to the paper P by operating the second thermal head 18 with the second transfer ribbon 17 as a thermal transfer member superimposed on the paper P. ing. The 20th transfer bomb 17 is fed out from the second feeding reel 19, passed between the second thermal head 18 and the conveyance path 1, and transferred to the second take-up reel 2.
It is designed to be wound to zero. In addition, as shown in FIG. 3(b), the second transfer ribbon 1 is printed on one side of +Jnx stick film or thin paper in the order of 7', macenter, and 1' yellow, each of the size of the paper P. It is made by repeatedly providing ink layers with a fantastic effect. The circumference of the winding drum 16 is longer than the length of the paper P. Further, the winding drum 16 is configured to rotate until the ink of each color is transferred to the paper P. Then, the paper 1' onto which the ink of each color has been transferred is peeled off by a peeling claw 2.

The pressurizing mechanism 7 presses the paper P that has passed through the second transfer mechanism 6 by one cut IJ-0-722, 22yc and discharges it into the storage section 3.

In the transfer process of the first and second thermal heads 12.18, as shown in FIG. 4, the ink surface of the transfer ribbon 11.17 and the paper P are overlapped, By heating from the opposite side, only the heated ink surface is separated and transferred onto the paper P.

According to the above configuration, the paper P supplied from the paper feed cassette 8 is smoothed by the smoothing lobes 10, 10' (from which the ink of the first and 20th converters 11 and 17 is rolled). , 1.l(+L'?) Although the paper P is smooth and warpage is still low, the transfer of -Jf and ri is carried out satisfactorily.

Furthermore, since the smoothness of the paper P is set to 50 = 2 tl O sand, the conveyance of the paper P is impaired, which inexplicably impairs good transfer. Further, the smoothness of s and lr is preferably 100 to 200 seconds, and as a result of experimental transfer, it was confirmed that there were no transfer errors.

It should be noted that the improvement in smoothness 1' by the smoothing rollers 10, 10 is greater than that by heating or humidifying the smoothing lobes 10, 10.
