上に飛翔させ、記録を行う構成がとられている。An inkjet recording device moves a carriage equipped with a head parallel to a platen that conveys a recording sheet, and during this movement, an ink chamber formed within the head is excited by an electro-mechanical transducer to generate ink droplets. A configuration is adopted in which recording is performed by making the image fly over the recording sheet.

でこするとインクが流れ、あるいは記録シートを重ね置
きした際に裏面に転写が生じ印字汚れを招く等の問題が
あった。However, in conventional inkjet recording devices, when dot density is increased in order to increase the recording density and obtain a clear image, dots overlap each other, so it takes time to dry the dot image, which means that the dot image cannot be fixed properly. (requires time for drying) and becomes undried. For this reason, there have been problems such as ink flowing when the recording sheet is rubbed by hand immediately after recording, or transfer to the back side when the recording sheets are stacked, resulting in print stains.
この問題を解消する手段として、シートパス上にヒータ

を覆うような構成にせざるを得ないため、記録直後の印
字や画像を目視することができないという欠点がある。One possible solution to this problem is to install a heater on the sheet path for forced drying, but since it has to be configured to cover the platen, it is difficult to visually check the print or image immediately after recording. The drawback is that it cannot be done.
本発明の目的は、このような従来技術の問題を解決でき
、記録直後の記録シート上のインクの定着の促進が可能
なインクジェット記録装置を提供することである。An object of the present invention is to provide an inkjet recording apparatus that can solve the problems of the prior art and can promote the fixation of ink on a recording sheet immediately after recording.

and the platen 1, and rotate the platen 1 or press the paper feed button to expose the leading edge of the recording sheet 2 from the paper cutter 8. When the recording start button is then pressed, the carriage 6 moves in the width direction of the recording sheet 2 based on the recording information, and the recording pad 7 is driven to fly ink droplets onto the recording sheet, thereby performing recording. Further, the pump 13 is driven at the start of recording.
At the same time, the heater 12 is energized. As a result, hot air heated by the heater 12 is sent through the tube 11 to the conduit 10 in the paper cutter 8, and the hot air is blown from the discharge port 9 onto the ink-adhering surface of the recording sheet 2. This hot air quickly fixes the recording ink.
