Zusammenfassung:PROBLEM TO BE SOLVED: To provide an inkjet printing device equipped with a head cleaning mechanism capable of maintaining cleaning performance.SOLUTION: The inkjet printing device comprises: a lengthy wiping member 8; a rolling-out mechanism 24 which rolls out the wiping member 8; a winding-up mechanism 26 which winds up the wiping member 8; a wiping roller 22, at least an outer periphery of which is formed of a soft material, whose outer periphery is wound with the wiping member 8; and winding holding mechanisms 30 and 32 which regulate respective positions of the rolling-out mechanism 24 side and the winding-up mechanism 26 side from a part 8a extended along the outer periphery of the wiping roller 22 and hold a state where the wiping member is wound around the wiping roller 22. The part 8a extended along the outer periphery of the wiping roller 22 of the wiping member 8 moves relatively to an ink discharge surface 14s while being pressed against the ink discharge surface 14s of an inkjet head 12.SELECTED DRAWING: Figure 3 【課題】クリーニング性能を維持することができるヘッドクリーニング機構を備えたインクジェット印刷装置を提供する。【解決手段】長尺状のワイピング部材8と、ワイピング部材8を巻き出す巻き出し機構24と、ワイピング部材8を巻き取る巻き取り機構26と、少なくとも外周が軟質材料からなり、外周にワイピング部材8が巻き掛けられるワイピングローラ22と、ワイピング部材8について、ワイピングローラ22の外周に沿っている部分8aより巻き出し機構24側と巻き取り機構26側のそれぞれの位置を規制して、ワイピングローラ22に巻き掛けられている状態を保持する巻き掛け保持機構30,32と、を備える。ワイピング部材8のうちワイピングローラ22の外周に沿っている部分8aが、インクジェットヘッド12のインク吐出面14sに押し当てられながらインク吐出面14sに対して相対的に移動する。【選択図】図3
