Abstract
Description
〔第1の実施形態〕
以下、本発明の実施形態に係るプリンタ(液体吐出装置)1及びインクジェットヘッド(液体吐出ヘッド)10について説明する。図1はインクジェットヘッド10の斜視図、図2はインクジェットヘッド10の正面図、図3はインクジェットヘッド10の図2におけるIII−III線で切断し矢印方向に見た断面図、図4は、インクジェットヘッド10に組み込まれた冷却ユニット100を示す分解斜視図、図5は、同インクジェットヘッド10の要部の断面図、図6は、インクジェットヘッド10の組立工程を示す斜視図、図7は、インクジェットヘッド10の組立工程を示す斜視図、図8は、インクジェットヘッド10の組立工程を示す斜視図、図9は、インクジェットヘッド10の組立工程を示す斜視図、図10は、インクジェットヘッド10の組立工程を示す斜視図である。
上述したように駆動制御用IC82からインナプレート41に伝わった熱は、サイドカバー30によって空冷されると共に、冷却ユニット100により冷却される。したがって、高い放熱効果が得られる。このため、駆動制御用IC82が過熱することによる不具合や、基準プレート60に対する吐出ユニット90の相対位置が高い精度で保たれると共に、インクの粘度上昇に伴う印刷品質の低下を防止することができる。
〔第2の実施形態〕
次に、第2の実施形態に係るインクジェットヘッド10Aを図11〜図13を用いて説明する。図11はインクジェットヘッド10Aの正面図、図12は、図11におけるVII−VII線で切断し矢印方向に見た断面図、図13は、インクジェットヘッド10Aの冷却ユニット130を示す分解斜視図である。なお、これらの図において、図1〜図10と同一機能部分には同一符号を付し、その詳細な説明は省略する。
