難であった。In general, IS media with good inter-absorption properties have ink on the surface.
There is a tendency for the expansion of Dora F to become large. For this reason, it was difficult to obtain records with a high degree of understanding of kanji and figures.

を提供するととKある。The purpose of this invention is DODII y lottery! It is possible to provide a recording device that is equipped with a hot air blowing device to enable recording with a high degree of flexibility by fixing with the hot air that blows out, and that is highly reliable.
本発明の特徴はプラテンの近傍の位置に熱風送風装置を
具備し九装置とするととで上記目的を達している。The present invention achieves the above object by providing a hot air blowing device in the vicinity of the platen.
以下、本発明について説明する。The present invention will be explained below.

の薫発速&に依存する。Generally, in an inkjet recording apparatus, fixing of ink attached to a recording medium is performed by ink permeation into the inside of the recording medium and evaporation of an ink solvent into the air. 16. The inter fixation time depends on the inter penetration speed RJ of the recording medium: the ink release speed &.

が必要である。Therefore, in a recording medium with a high ink permeation rate, the degree of printing clarification will decrease.On the other hand, in a recording medium that can perform high resolution 111 degree recording, the permeation rate of Ink I is slow, and ink fixation is mainly caused by the ink solvent. (by evaporation). Therefore, when a recording medium capable of high-resolution recording is used in a conventional inkjet recording apparatus, a considerably long time is required for the ink to fix.

図である。Therefore, in the present invention, as shown in FIG. 3, a small hot air blower ftt12 is provided in the vicinity of the platen 1 of the conventional DOD type inkjet recording device, for example, on the top of the platen 1. The air outlet 13 is located in the opposite direction to the direction in which the print head 7 is located, and the hot air blown out from the air outlet 13 heats the ink attached to the recording medium 11. FIG. 4 shows the hot air of the present invention. It is a front view showing an example of an air blower.

ファン15と送風口130間に熱源(ヒータ岬)16を
設け、ファン15を回転させて上記送風口13より熱風
を吹き出す。In the figure, the hot air blowing device 12 is provided with a blowing port 13 (a groove in this embodiment) having a length equal to the width of the carrier movement so that one line printed on the recording medium 11 by the print head can be dried at the same time. Furthermore, in the air pipe 14,
A heat source (heater cape) 16 is provided between the fan 15 and the air outlet 130, and the fan 15 is rotated to blow out hot air from the air outlet 13.

品位が低下する。そこで、熱風送風装置12の送風口1
3の方向は第3図に示すようにプリントヘッド7が位置
する方向とは反対にしている。Since the diameter is 60 to 1100 Aφ, if wind or the like hits from outside while the ink particles are flying, the flying direction of the ink particles will be disturbed and the printing quality will be degraded. Therefore, the air outlet 1 of the hot air blower 12
The direction of 3 is opposite to the direction in which the print head 7 is located as shown in FIG.

する。Further, for safety reasons, the hot air blower 12 preferably has a function that starts operating after a recording medium is set in the recording device. Furthermore, the fan 15 is designed to also serve as a cooling fan for an electric circuit board in the inkjet recording apparatus, and the electric circuit board is placed, for example, in section A in FIG. 4.
上記構造の熱風送風装置12を用いて、記録媒体11温
度を変化させてインク定着時間の関係を調べた。Using the hot air blower 12 having the above structure, the temperature of the recording medium 11 was varied to examine the relationship between the ink fixing time.

記録媒体について実験した。FIG. 5 shows the relationship between the inside of the recording medium and the ink fixing time, where the vertical axis kt! Experiments were conducted on three types of recording media, with the temperature of the recording medium plotted on the horizontal axis and the fixing time of one dot of ink attached to the sickle medium.

ンクはほぼ完全な円形でドツトの拡がシは記録媒体■の
1/2程度で、漢字などの高解偉度の記録が行々えた。By increasing the temperature of the recording medium, the ink fixing time could be shortened. The ink fixing time for the recording medium (1) at room temperature was about 20 minutes on average for alphanumeric characters, and about 50 minutes on average for solid black. In addition, the ink fixation time for recording medium ■ is approximately 40 seconds on average for alphanumeric characters, and 60 seconds for solid black.
It was about seconds. Here, the recording medium (2) absorbs ink more easily into the recording medium than the recording medium (I), and the spread of dots and smearing on the surface are large. When printing on medium ■, the ink was almost completely circular and the dot spread was about 1/2 that of recording medium ■, making it possible to record high-resolution characters such as kanji.
記録媒体の温度を704Cまそ増加するとと、インク定
着時間は1ドツトで10秒以下となった。When the temperature of the recording medium was increased by 704C, the ink fixing time became 10 seconds or less for one dot.

インクの定着時間は記録媒体Iに比べ短かかった。この
記録媒体!ではインク定着時間10秒以下とするのに、
温度は60℃で十分であった。The dots on recording medium 1 are wider than recording medium I, but
The fixing time of the ink was shorter than that of Recording Medium I. This recording medium! So, the ink fixing time should be 10 seconds or less,
A temperature of 60°C was sufficient.
以上のように記録媒体上のインク定着時間は使用する記
録媒体の種類に依存し、また熱風送風により加熱された
記録媒体の温度に依存する。As described above, the ink fixing time on a recording medium depends on the type of recording medium used, and also depends on the temperature of the recording medium heated by hot air blowing.
また、第6図に示すように記録媒体I上のドツト径は記

記録しれときと同程度の印字品位が得られた。Furthermore, as shown in FIG. 6, the dot diameter on recording medium I remained almost constant even when the temperature of the recording medium increased. In this apparatus, the temperature of the recording medium was set to 70°C and recording was performed, and as a result, the recording medium 1. In both cases of Il and I[l, print quality comparable to that obtained when recording at room temperature was obtained.

インク定着効果が得られた。The required ink fixing time is v! The structure of the brass device may vary.
In the case of color recording compared to monochromatic recording, a shorter fixing time is required. It is desirable to select a recording medium and change the temperature setting value of the recording medium according to these requirements. In order to maintain the temperature of the hot air blower 12 at a predetermined temperature KM, the temperature of the recording medium 11 is measured by a detector 17 as shown in FIG.
The temperature of the hot air is detected by the temperature control circuit 18 through the feedback system.The temperature of the hot air is controlled by the temperature control circuit 18 using the heat source 170 described above and a harmonica heater for warm air (heating amount 200W) consisting of 1 POSISTOR and the air flow rate of 2m/S. When the temperature of the blown air was about 100° C., similar ink fixing effects were obtained.

きい。The present invention has been made according to the embodiments described above, and according to the present invention, a hot air blower is provided at a position near the platen.
By using the apparatus in which the ink particles attached to the recording medium are blown out, a recording result with a high degree of resolution can be quickly fixed by the hot air blown out. Compared to conventional DOD type inkjet recording devices, it has a great effect of being able to perform recording with higher resolution.
