Abstract: The liquid ejection device 1 includes a carriage 100 whose internal space S is partitioned into a first space S1 and a second space S2 by a partition plate 106, an ejection head 101 that is provided in the first space S1 and that ejects a liquid, and a control substrate 102 that is provided in the second space S2 and that controls a drive of the ejection head 101, wherein the control substrate 102 is connected to the ejection head 101 via a substrate-to-substrate connector 103, and the partition plate 106, as viewed from a direction D in which the control substrate 102 is connected to the ejection head 101, is shaped such that at least one region of region where the control substrate 102 is located, the region where the substrate-to-substrate connector 103 is located, and the region where the ejection head 101 is located, is cut out.

Abstract: Provided is a method for manufacturing a coil unit that is suited to the bulk manufacturing of multiple sets of coil parts for a multi-axis linear motor actuator. This method of manufacturing a coil unit for a multi-axis linear motor actuator, which is constituted by disposing multiple sets of linear shaft motors 10 in a line at a prescribed pitch, includes: a step in which a coil fixing member 50 is prepared that holds receiving parts 51 that are capable of receiving multiple coil parts 15, which are equal in quantity to the multiple sets of linear shaft motors, with the coil parts being arranged in a line at the prescribed pitch; a step in which the multiple coil parts are disposed by being arranged in a line and secured to the coil fixing member; and a step in which electromagnetic shielding plates 70 that are longer than the coil parts are disposed along a center axis direction at locations corresponding to the spaces between at least adjacent coil parts among the multiple coil parts disposed in the line.
