不鮮明で印字品質が低下するという欠点を有している。1. Prior Art 1 Inkjet recording is excellent in quietness during recording and high-speed printing performance. BACKGROUND ART Liquid ink compositions based on water or the like have conventionally been used as ink compositions for inkjet recording. However, since ink is recorded by soaking into the paper, it has the disadvantage that when recording on paper where ink easily soaks, bleeding occurs, the periphery of the recorded dots becomes unclear, and the print quality deteriorates.

Using a hot-melt ink composition based on a wax or the like that is solid at room temperature, as shown in Japanese Patent Application Laid-open No. 9383 and Japanese Patent Application Laid-open No. 58-108271, the solid ink is melted by heating at a high temperature and then blown onto the recording paper. A hot-melt inkjet recording device is known that forms recorded dots by cooling and solidifying the ink.

問題を有している。。[Problems to be Solved by the Invention] However, although conventional hot-melt inkjet recording devices can obtain good print quality regardless of paper quality, ink droplets swell up on the recording paper surface as shown in Figure 3. Because it solidifies in a state where it is
They have problems such as peeling off due to external friction, heat, pressure, etc., sticking to stacked objects, and causing printing to bleed. As a method to solve this problem, methods have been tried to fix the ink composition after flying and adhering using a roll heater, a light source, etc., but all of these methods consume a large amount of power and also require heat to be applied during the device operation. This poses a problem in that the device itself is complicated and cannot be miniaturized. .
本発明は、これらの課題を解決するものであり、その目
的とするところは、記録紙の紙質に関係なく定着強度が
良好で高い印字品質が得られるインクジェット記録装置
を提供するところにある。The present invention is intended to solve these problems, and its purpose is to provide an inkjet recording device that has good fixing strength and can provide high print quality regardless of the quality of the recording paper.

着するサーマルヘッドを有することを特徴とする。1. Means for Solving Problems] The inkjet recording device of the present invention is an inkjet recording device that flies an ink composition at a temperature higher than room temperature, and a thermal fixing method that heats and fixes the ink composition after flying and adhering. It is characterized by having a head.
本発明°のサーマルヘッドは、インクジェットヘッドの
ドツトピッチと同一のものであれば、従来公知のものが
そのまま使用できる。本発明によればサーマルヘッドを
用いるため消費電力も小さく、その上印字されたドツト
だけを選択的に加熱定着できるため無駄な電力消費を避
けることができる。As the thermal head of the present invention, any conventionally known thermal head can be used as is, as long as it has the same dot pitch as an inkjet head. According to the present invention, since a thermal head is used, power consumption is low, and in addition, only printed dots can be selectively heated and fixed, thereby avoiding wasteful power consumption.
サーマルヘッドの発熱温度は、インクの物性や印字速度
にもよるが、融点近傍、具体的には融点より１０°Ｃ低
い温度から融点より３０°Ｃ高い温度の範囲が適してお
り、融点より２°Ｃ低い温度から融点より２０°Ｃ高い
温度の範囲が更に遺している。The temperature at which the thermal head generates heat depends on the physical properties of the ink and the printing speed, but it is suitable to be in the vicinity of the melting point, specifically in the range of 10°C lower than the melting point to 30°C higher than the melting point, and 20°C higher than the melting point. A further range of temperatures from 20°C below the melting point remains.
融点より高すぎるとにじみや印字つぶれを生じ、融点よ
り低すぎると定着が不十分で密着性や、耐擦性が得られ
ない。If the temperature is too high than the melting point, smearing or printed characters will occur, and if it is lower than the melting point, the fixing will be insufficient and adhesion and abrasion resistance will not be obtained.

で解決できる。When ink ejected by an inkjet head and cooled and solidified is heated and fixed by a thermal head, there is a problem that the ink comes into direct contact with the thermal head, staining the thermal head. This problem can be solved by heat fixing using an ink-repellent film such as naphthalate or polytetrafluoroethylene.

ができる。[Function] In the inkjet recording device of the present invention, the ejected ink collides with the recording paper, cools and solidifies, and is then heated and fixed by the thermal head, thereby flattening the dots as shown in FIG. Since a part of the adhesive penetrates into the fibers near the surface of the recording paper and is re-assimilated, it has good fixing strength and one-shot resistance, and it is possible to obtain high adhesion and high print quality.

が行われる。FIG. 1 is a perspective view of an inkjet recording apparatus showing an embodiment of the present invention. In this figure, recording paper 10 is wound around platen 11 and is pressed by feed rollers 12, 13. An inkjet head 16 and thermal heads 18a and 18b are mounted on both sides of the inkjet head 16 on a carriage 15 that is guided by guide shafts 14 and 17 and movable in a direction parallel to the platen axis. The inkjet head 16 has a plurality of nozzles that can independently control the ejection of ink droplets, and is scanned in the platen axis direction, selectively ejecting ink droplets from the nozzles to form an ink image on the recording paper 10. A thermal head 18a is provided on both sides of the inkjet head 16 and has a plurality of heating elements that can also independently control dot heating.
18b follows the inkjet head 16 and scans in the platen axis direction, and in the case of unidirectional printing, the thermal head 18
Only a generates heat, and in the case of bidirectional printing, the thermal head 18a is used when printing in the right direction, and the thermal head 18 is used when printing in the left direction.
b generates heat and selectively heats and fixes the ink image formed by the inkjet head. The recording paper 10 is conveyed in a sub-scanning direction perpendicular to the scanning direction by rotation of a platen 11 and feed rollers 12 and 13, and printing is performed on the surface of the recording paper.
該サーマルヘッドの発熱時の温度は、先にも述べたよう
にインクの融点近傍に制御される。The temperature of the thermal head when it generates heat is controlled to be close to the melting point of the ink, as described above.
