Abstract: A head unit includes a common passage, at least one recording head, and a joint mechanism. The joint mechanism has a first valve and couples the common passage to the recording head. The first valve includes: a first stopper having a switch member with an insertion hole and an engagement boss projecting from its inner surface, a sliding portion inserted in the insertion hole slidably up and down, and an engagement groove engaged with the engagement boss; and a first sealing member fitted on the first stopper to be in contact with or away from the insertion hole's inner surface. Rotating the switch member to move the first stopper up/down causes the first valve to switch between a closed state, with the first sealing member in contact with the insertion hole's inner surface, and an open state, with the first sealing member away from the insertion hole's inner surface.

Abstract: A liquid discharge head includes a flow channel member, a pressurization part, a plurality of discharge holes, a flexible substrate, a cover member, and a heater. The flow channel member includes a first surface and a second surface that is positioned on an opposite side of the first surface. The pressurization part is positioned on the first surface. The plurality of discharge holes are positioned on the second surface. For the flexible substrate, a one-end part thereof that is positioned on the pressurization part is electrically connected to the pressurization part. The cover member covers the one-end part of the flexible substrate. The heater is positioned on the cover member.

Abstract: A head unit includes a common passage, at least one recording head, and a joint mechanism. The common flow passage has a liquid feed passage through which to pass at least one kind of liquid including ink. The recording head is attachable and detachable to and from the common flow passage, and has nozzles through which to eject the ink. The joint mechanism couples the liquid feed passage to a liquid feed port in the recording head, and has a first valve for opening and closing the liquid feed passage and a coupling member for coupling the first valve to the liquid feed port. In the top surface of the coupling member is a liquid reservoir portion for storing, when the recording head is removed from the common flow passage with the first valve closed, ink left between the first valve and the coupling member.
