To protect a circuit board from mist.SOLUTION: A circuit unit arranged closer to a downstream than a printing head has a circuit board, a cover that surrounds an opposing surface opposing to a support part for supporting a printing medium and stores the circuit board, a first gas inflow port formed on a first surface of the cover and a first duct formed on the first surface and communicated with the first gas inflow port. A slide mechanism, which supports the circuit unit movably in a first direction in which the unit approaches the support part and in a second direction, the opposite direction of the first direction, has a stationary frame for supporting the circuit unit, a second gas inflow port formed in the stationary frame, which is formed at a position opposing to the first gas inflow port when the circuit unit is at a first position where the unit approaches the support part, and a second duct formed in the stationary frame and communicated with the second gas inflow port. When the circuit unit is at the first position, the first duct engages with the second duct to form a third duct through which the first gas inflow port is communicated with the second gas inflow port.SELECTED DRAWING: Figure 7 【課題】回路基板をミストから保護する。【解決手段】印刷ヘッドより下流に配置された回路ユニットは、回路基板と、印刷媒体を支持する支持部と対向する対向面を囲み且つ回路基板を収容するカバーと、カバーの第１面に形成された第１気体流入口と、第１面に形成されて第１気体流入口に連通する第１ダクトと、を有し、回路ユニットを支持部へ接近する第１方向と第１方向の逆の第２方向とに移動可能に支持するスライド機構は、回路ユニットを支持する固定フレームと、固定フレームに形成された第２気体流入口であって、回路ユニットが支持部に接近した第１位置に在る場合に第１気体流入口と対向する位置に形成された第２気体流入口と、固定フレームに形成されて第２気体流入口に連通する第２ダクトと、を有し、回路ユニットが第１位置に在る場合に、第１ダクトと第２ダクトとが係合することにより第１気体流入口と第２気体流入口とを連通させる第３ダクトが形成される。【選択図】図７
