場合でも濃淡の度合いが異なる複数のインクが使用され
、このような異なるインクを使用するインクジェット記
録装置ではキャリジ上にインクの種類に応した複数の記
録ヘッドが搭載される。For color printing, four colors, cyan, magenta, yellow, and black, are usually used, and even for the same hue (black, etc.), multiple inks with different degrees of shading are used, and these different inks are used. In an inkjet recording apparatus, a plurality of recording heads corresponding to the type of ink are mounted on a carriage.
各記録ヘッドの前面にはドツトを形成する複数の小口す
なわちインク吐出口が形成されているが、この面に付着

ンクなどによりインク吐出口が目詰まりし、インク吐出
不良になることがある。The front surface of each recording head has a plurality of small holes, or ink ejection ports, that form dots, but the ink ejection ports become obstructed by paper scraps and dust that adhere to this surface, or ink that has thickened due to evaporation of solvent. It may become clogged and cause ink ejection failure.
このため、インク吐出口が形成された面（記録ヘッド前
面）をクリーニングすることが要請される。Therefore, it is required to clean the surface (the front surface of the recording head) where the ink ejection ports are formed.
このクリーニング手段として、プラスチックシートなど
で作った可撓性のブレードで記録ヘッド前面をワイピン
グ（拭き払い）する機構が提案されている。As this cleaning means, a mechanism has been proposed in which the front surface of the recording head is wiped with a flexible blade made of a plastic sheet or the like.
しかし、従来のインクジェット記録装置にあっては、キ

イパーを設けるので、構造が複雑で大型になるという問
題があった。However, in conventional inkjet recording devices, multiple wipers corresponding to the number of recording heads are provided at the wiping position within the carriage movement range (for example, a position to the right of the home position), resulting in a complex and large structure. There was a problem.
また、ワイパーは一般に可撓性のブレードを往復動させ
るなどして複数回の拭き払いを行う機構のものであった
が、従来構造では、いったん７’Ｌ／−ドで拭き取った
付着物が次のワイピング動作時に記録ヘッドに再び付着
することがあり、ワイピング効果が不充分になりやすい
という問題があった。In addition, wipers generally have a mechanism that wipes away multiple times by reciprocating a flexible blade, but with the conventional structure, the deposits that have been wiped off with a 7'L/- There is a problem that the wiping effect tends to be insufficient because it may adhere to the recording head again during the wiping operation.
本発明の目的は、このような従来技術の問題を解決でき
、簡単な構造で複数の記録ヘッドを効果的にワイピング
できる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 effectively wipe a plurality of recording heads with a simple structure.
