摘要： 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.

摘要： 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 having a discharge hole for discharging a liquid therethrough, a driver IC configured to control driving of the head body, a casing which is disposed on the head body and has openings on a side surface of the casing, and a heat sink which is disposed on the openings of the casing and configured to dissipate heat generated in the driver IC, and a thermal insulation part disposed between the heat sink and the head body. This makes it possible to reduce the likelihood that the heat of the heat sink transfers to the head body.

摘要： A liquid discharge head including first flow channel members, each having discharge holes, pressurizing chambers, first common supply flow channels, and first common recovery flow channels where the first common supply flow channels and first common recovery flow channels are long in a first direction, and the first flow channel members are disposed in a second direction; a second flow channel member having a second common supply flow channel and a second common recovery flow channel; and pressurizing parts to respectively pressurize the liquid in the pressurizing chambers. The second flow channel member is disposed on the first flow channel member. The first flow channel member, second flow channel member, second common supply flow channel, and second common recovery flow channel are long in the second direction. Pressure loss may therefore be minimized in the pressurizing chambers without increasing the size of the liquid discharge head in a planar direction.

摘要： A liquid discharge head and a recording apparatus are each capable of reducing a malfunction possibility that occurs on a piezoelectric actuator substrate due to contact between individual electrodes and a liquid. The liquid discharge head includes a head body including a flow channel member, a piezoelectric actuator substrate having a plurality of individual electrodes, a flexible wiring substrate, and an adhesive member adhering the flexible wiring substrate and head body, and surrounds the individual electrodes. When a surface of the head body surrounded by the adhesive member is a first region, and a surface of the head body other than the first region is a second region, the head body has a first through hole connecting the first region and the second region to permit communication between a space surrounded by the flexible wiring substrate, adhesive member, first region, and an outside other than the space.
