PROBLEM TO BE SOLVED: To provide a liquid discharge device which can discharge a liquid at a desired position.SOLUTION: A liquid discharge device of the invention includes: a movable body having a driving source; and a liquid discharge part which is provided at the movable body and discharges a liquid to the outer side of the movable body. Further, the liquid discharge device includes: a control unit which controls a discharge amount of the liquid; and a detection part which detects an object. The control unit adjusts the discharge amount of the liquid on the basis of a detection result of the detection part. Further, the control unit moves the movable body closer to the object to cause the liquid to be discharged if the detection part detects the object.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】所望の位置で液体を放出することができる液体放出装置を提供すること。【解決手段】本発明の液体放出装置は、駆動源を有する移動体と、前記移動体に設けられ、液体を前記移動体の外側に放出する液体放出部と、を備える。また、前記液体の放出量を制御する制御部と、対象を検出する検出部とを備え、前記制御部は、前記検出部の検出結果に基づいて、前記液体の放出量を調整する。また、前記制御部は、前記検出部が前記対象を検出した場合、前記移動体を前記対象に接近させて前記液体を放出させる。【選択図】図1
