    Abstract: A liquid ejection head in the present disclosure includes a first channel member including a first surface, a plurality of ejection ports in the first surface, a plurality of pressurizing chambers individually communicated with the plurality of ejection ports, and a second surface on the opposite side to the first surface; with a pressurizing member on the second surface; and with a second channel member including a third surface, a fourth surface on the opposite side to the third surface, a raised part which protrudes from the fourth surface, and a first through hole in the raised part. The second channel member is provided on a region in the second surface of the first channel member, in which the pressurizing member is not arranged. When viewed on a plane, an outer circumference of the raised part is located on inner side from an outer circumference of the fourth surface.

    Abstract: A liquid discharge head is provided in which heat of a heat sink is less apt to transfer to a head body. The liquid discharge head includes a head body 2a having a discharge hole for discharging a liquid therethrough, a driver IC 93 configured to control driving of the head body 2a, a casing 91 which is disposed on the head body 2a and has openings 91a and 91b on a side surface of the casing, and a heat sink 90 which is disposed on the openings 91a and 91b of the casing 91 and configured to dissipate heat generated in the driver IC 93, and a thermal insulation part 91e disposed between the heat sink 90 and the head body 2a. This makes it possible to reduce the likelihood that the heat of the heat sink 91e transfers to the head body 2a.

    Abstract: A coating device includes a head, an arm, and a controller. The head includes a nozzle surface. The arm holds the head. The controller controls movement of the head via the arm. The controller vibrates the head in a second direction intersecting a first direction, and/or rotationally oscillates along a nozzle surface while moving the head in the first direction along the nozzle surface in a state where the nozzle surface and a to-be-coated object face each other.

    Abstract: A liquid ejection head having a channel member which includes an ejection hole surface and a pressurization chamber surface opposite thereto. An actuator substrate overlaps the pressurization chamber surface. The channel member includes a plurality of ejection holes opening in the ejection hole surface, a plurality of pressurization chambers individually communicating with the plurality of ejection holes and arranged in plan view of the pressurization chamber surface, and a plurality of dummy pressurization chambers positioned outside of the predetermined region in plan view of the pressurization chamber surface. The actuator substrate includes a plurality of pressurization portions that individually pressurize the pressurization chambers, and a plurality of dummy pressurization portions that individually pressurize the dummy pressurization chambers. The dummy pressurization chambers communicate with each other via a plurality of communication paths. A closed space including the plurality of dummy pressurization chambers and the plurality of communication paths is hermetically closed.
