Abstract

An apparatus capable of obtaining a high-quality picture is provided for each person at a low price. The sublimation ink remaining after a picture has been recorded by a rotary sublimation thermal head is gasified by sublimation heater rolls, and a gas thus obtained is mixed in a solid or a liquid with a solvent in a receptacle, the resultant mixture being applied again to dry the solvent and form a uniform solidified coat layer, which is reused by the recording head.

Description

Ming ink dispenser

Technical field

The present invention is a new method of removing all residual sublimation ink in a sublimation recycling method. Of course, general printers can be used for full-color printers such as copy printers, video signals, and recording color printers.

In order to provide an effective printer in terms of low cost, excellent image stability, and easy operability j, it uses next-generation photographic technology with higher image quality than photography. Background art

Conventional sublimation recycling type printers remove sublimation ink recorded and remaining on the sublimation ink carrying sheet by mechanical force or by heat or melting to remove the entire melted sublimation ink. It is aimed at. It is as described in Japanese Patent Application Publication No. Hei. Disclosure of the invention

The present inventor has conducted an experiment on the complete removal of Patent Application Publication No. Heisei 1-305529, and found that the mechanical force due to the mechanical force could not be used to remove the sheet due to the depressing force and the entire surface could be removed. The entire surface could not be removed, and the high speed during sheet rotation was not enough, so the entire surface was difficult to remove by melting by melting, and the equipment became large. In addition, all of these were used, but it was difficult to remove the entire surface, but it was difficult for the i and the sheet rotating speed to be large.

New paper According to the present invention, the entire surface can be removed with a simple configuration. [9] The high image quality was obtained stably, the print speed was increased, and the equipment was very small. Specifically, a roll heater is provided on the inner surface of the seamless sheet, and this generates heat that sublimates the maximum remaining sublimation ink of the seamless sheet. BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 is a drawing of the physical principle of the present invention, which changes near the triple point. FIG. 2 is a sectional view of the structure of the present invention. FIG. 3 is a schematic diagram of the product of FIG. 2 of the present invention in four or three colors. BEST MODE FOR CARRYING OUT THE INVENTION

The sublimation residual ink that has passed through the sublimation recording head of the sublimation recording apparatus is vaporized by the sublimation heater of the present invention, and the sublimation ink is liquefied into the melt in the tray. This is re-coated with the application roller. At this time, since the residual heat from the sublimation heater roll remains on the seamless sheet, it is naturally dried in the receiving dish, melted, and re-coated into a uniform solid. Alternatively, the melt is removed by a melt removal heater. This recycling records the i9 sublimation recording head. The sublimation heater roll and the melt removal heater are ceramic heaters.

In this embodiment, the recording speed of the sublimation recording head is increased as a rotating thermal head. A seamless sheet was covered with the sublimation recording head, the sublimation thermal roll of the present invention, and the melt removal roll. These three points were made into isosceles triangles or equilateral triangles with the head at the sublimation record head, and the roll diameters of these three points were the same. The sublimation thermo roll of the present invention sequentially provided heat to be vaporized in the direction of the tray, that is, in the downward direction of the mouth. The sublimated heat roll, coating roll and melt removal roll made the rotation of the seamless sheet the same in the forward direction.

New paper The ink gettered in the dissolved water is applied to the seamless sheet by a roll. For the saucer as a getter, both sides of the cross-sectional view were pressed into contact with each other in the form of an s-shaped panel.

In the drawing, S1 is a sublimation recording rotary thermal head, S2 is a sublimation heater roll, R1 is a coating roll, S3 is a melt removal heater roll,; 4 is a combination of 4 and 3 in Fig. ^2. 1 is yellow, 2 is magenta, 3 is cyan, and 4 is black color, depending on the input signal! ) Controlled. 1-4 can be replaced with a cartridge type. Also, only 1 to 4 trays can be replaced with cartridge type. In addition, only ink will be exchanged. Industrial applicability

According to the present invention, a single printer is used to provide a small-sized device for one color, and the size of the entire device is very small, so that a high-quality picture is printed as compared with a photograph having stable images. I was like
