Description
【発明の詳細な説明】 （技術分野） 本発明はカラープリンタなどの複数のインクジェット記
録ヘッドを備えたインクジェット記録装置における記録
ヘッドの温度制御に関する。Description: TECHNICAL FIELD The present invention relates to temperature control of a recording head in an inkjet recording apparatus including a plurality of inkjet recording heads such as a color printer.
（従来技術） プリンタやファクシミリなどの記録装置にあっては、複
数の色または濃淡を組合わせて印字する場合、その種類
に応じた数の記録ヘッドが使用される。例えば、カラー
印字用のものでは通常シアン、マゼンタ、イエロー及び
ブラックの４色が使用され、したがって４個の記録ヘッ
ドが搭載されている。(Prior Art) In a recording device such as a printer or a facsimile, when a plurality of colors or shades are combined and printed, a number of recording heads corresponding to the type are used. For example, for color printing, four colors of cyan, magenta, yellow and black are usually used, and therefore four recording heads are mounted.
印字方法としてはインクジェット式、サーマル式あるい
はワイヤドット式などが採用されている。As a printing method, an inkjet method, a thermal method, a wire dot method, or the like is adopted.
また、インクジェット式には、インクの吐出手段として
ピエゾ素子等の電気機械エネルギーを変換体を用いたも
のや、発熱抵抗体等の電気熱エネルギー変換体を用いた
ものがある。Further, in the ink jet type, there are a type using an electromechanical energy converter such as a piezo element or the like using an electrothermal energy converter such as a heating resistor as an ink ejecting means.
インクジェット式は、記録ヘッドからそれぞれ異なる色
や濃度の異なるインクを吐出して印字することが可能で
あり、それら複数のインクに対応した複数の記録ヘッド
を近接して配置することが可能である。また、インクジ
ェット式の機構上の特徴から、サーマル式を用いた熱転
写記録方式および感熱記録方式に比べて、カラー化を容
易に達成することができる。The inkjet type can print by ejecting inks of different colors and different densities from the recording heads, and a plurality of recording heads corresponding to the plurality of inks can be arranged close to each other. Further, due to the characteristic of the ink jet type mechanism, colorization can be easily achieved as compared with the thermal transfer recording method and the thermal recording method using the thermal type.
ところで、インクジェット式（特に電気熱変換体を用い
たバブルジェット式）やサーマル式などでは記録ヘッド
のドット形成素子を電気熱エネルギー変換体（発熱抵抗
体など）で駆動するので、記録ヘッドの温度が印字品質
に直接的に影響を及ぼすことになる。By the way, since the dot forming element of the recording head is driven by the electrothermal energy converter (heating resistor, etc.) in the ink jet type (particularly, bubble jet type using the electrothermal converter) or the thermal type, the temperature of the recording head is It will directly affect the print quality.
例えば、インクジェット記録装置にあってはインクジェ
ット記録ヘッドの温度によってインク吐出口部分のイン
クの性状（粘度など）が変化し、該インク性状の変化に
起因して吐出量等の吐出特性に変動が生じて印字品質を
劣化させることとなる。そのため、温度によらず印字品
質を所定範囲内に制御することが要求される。For example, in an ink jet recording apparatus, the ink properties (viscosity, etc.) of the ink ejection port change depending on the temperature of the ink jet recording head, and the ejection characteristics such as the ejection amount vary due to the change in the ink properties. Printing quality is deteriorated. Therefore, it is required to control the print quality within a predetermined range regardless of the temperature.
また、電気熱エネルギー変換体を用いたインクジェット
式に限らず、電気機械エネルギー変換体を用いたインク

実される。Further, the temperature of the ink jet recording head is not limited to the ink jet type using the electrothermal energy converter, but also in the ink jet recording apparatus using the electromechanical energy converter, the temperature of the ink jet recording head depends on the ambient temperature and the printing operation time. The temperature control of the recording head is enhanced by detecting the temperature of the recording head and activating various means for heating or heat dissipation by the CPU (control circuit) based on the detected temperature.
しかし、従来の複数の記録ヘッドを備えた記録装置にあ

ので、温度検出器および入出力ポートの数が複雑になり
構造が複雑になるという問題、検出制御時間が長くなり

た。However, in a conventional recording apparatus having a plurality of recording heads, each recording head has a temperature detector attached, so that the number of temperature detectors and input / output ports is complicated, and the structure is complicated. However, there are disadvantages such as the problem that the control becomes long and the detection control time becomes long and it is difficult to cope with the high speed operation.
