Summary: | To reduce the number of components of a diaphragm pump.SOLUTION: A flow path member of a liquid discharge head is provided between a liquid discharge module for discharging a plurality of liquids and a plurality of liquid storage parts for storing the plurality of liquids. The flow path member has a plurality of flow paths for connecting the plurality of liquid storage parts and the liquid discharge module and circulating each of the plurality of liquids, and a plurality of diaphragm pumps 230 that are provided on each of the plurality of flow paths and give a pressure to the corresponding liquid, and is integrated with at least two diaphragm pumps 230.SELECTED DRAWING: Figure 6
【課題】ダイヤフラムポンプの部品点数を削減する。【解決手段】液体吐出ヘッドの流路部材は、複数の液体を吐出する液体吐出モジュールと、複数の液体を貯留する複数の液体貯蔵部と、の間に設けられる。流路部材は、複数の液体貯蔵部と液体吐出モジュールとを接続し、複数の液体が各々流通する複数の流路と、複数の流路に各々設けられ、対応する液体に圧力を与える複数のダイヤフラムポンプ230と、を有し、少なくとも2つのダイヤフラムポンプ230が一体化されている。【選択図】図6 |
