To provide a position adjustment mechanism of a guided member to improve positioning accuracy of a nozzle surface recovery device.SOLUTION: A nozzle surface recovery device 200 has: caps 240 which are attached to a nozzle surface of a droplet discharge head 100 having the nozzle surface formed with multiple nozzles 104 for discharging droplets; and guided members (first rollers 220 and second rollers 230) which are guided by guide members (guide rails 280, 290) and moves along the guide members relative to the droplet discharge head 100 to be in a capping position where capping of the nozzle surface may be performed and a retreat position. The nozzle surface recovery device 200 has first position adjustment mechanisms (first adjustment plates 221) each of which moves the guided member in a manner that enables adjustment of relative heights of the nozzle surface and the cap.SELECTED DRAWING: Figure 7A 【課題】被ガイド部材の位置調整機構を設けることによってノズル面回復装置の位置決め精度を向上する。【解決手段】液滴を吐出する複数のノズル１０４が形成されたノズル面を有する液滴吐出ヘッド１００のノズル面に被着するキャップ２４０と、ガイド部材（ガイドレール２８０、２９０）にガイドされる被ガイド部材（第１コロ２２０、第２コロ２３０）とを有し、液滴吐出ヘッド１００に対してガイド部材に沿って相対的に移動することにより、ノズル面のキャッピング可能位置と退避位置とを採るノズル面回復装置２００において、被ガイド部材を、ノズル面とキャップの相対高さを調整可能に移動する第１の位置調整機構（第１調整板２２１）を有することを特徴とする。【選択図】図７Ａ
