To provide a liquid discharge device which enables reduction of energy consumption related to prevention of dryness in a path from a head cap placed in contact with a droplet discharge head and a storage tank.SOLUTION: A liquid discharge device includes: a droplet discharge head which discharges droplets; a head cap which covers a nozzle surface included in the droplet discharge head; a buffer tank which is installed at a downstream side of the head cap and temporarily stores a liquid; a first communication passage which allows the head cap and the buffer tank to communicate with each other; a first heater which heats the liquid stored in the buffer tank; and a first waste heat introduction passage which introduces exhaust heat discharged from a heat source in the device into the buffer tank.SELECTED DRAWING: Figure 3 【課題】液滴吐出ヘッドに当接させたヘッドキャップから貯蔵タンクへの経路の乾燥防止に係るエネルギー消費を低減できる液体吐出装置を提供する。【解決手段】液滴を吐出する液滴吐出ヘッドと、液滴吐出ヘッドが有するノズル面をカバーするヘッドキャップと、ヘッドキャップの下流側に設置され、液を一時的に貯留するバッファタンクと、ヘッドキャップとバッファタンクを連通する第一連通路と、バッファタンクに貯留された液を加温する第一ヒーターと、装置内の熱源から排出される排熱をバッファタンクに導入する第一排熱導入路と、を備える液体吐出装置による。【選択図】図３
