Abstract: Provided is a liquid ejecting apparatus capable of suppressing ink from remaining on a nozzle surface.A liquid ejecting apparatus includes a head unit 16 capable of ejecting a liquid from a nozzle 27 provided in a nozzle surface 22a of a nozzle plate 22, an anchoring plate 17 in which the head unit 16 is anchored and that is provided with an opening region 17a that exposes the nozzle surface 22, and a wiper member 12 that wipes an anchoring plate exposed-surface 17b located on the opposite side of the head unit 16 of the anchoring plate 17 and the nozzle surface 22a. When an angle of contact between the nozzle surface 22a and the liquid is taken as θn, an angle of contact between the anchoring plate exposed-surface 17b and the liquid is taken as θs, and an angle of contact between the wiper member 12 and the liquid is taken as θw, the relationship θn>θs>θw>90° is fulfilled.

Abstract: A liquid ejecting head comprises a unit head bonded to a communication substrate. Liquid chamber forming portions are formed in the unit case, along a first direction at positions that are separated by a partition wall. Empty liquid chamber portions and supply-side communication paths are formed in the communication substrate. The supply-side communication paths include a common communication path formed in an opposite side with a thin thickness portion left in the surface side of the communication substrate, and individual communication paths. With a surface of the partition wall and a surface of the thin thickness portion bonded together, the empty liquid chamber forming portions and the empty liquid chamber portions communicate with each other so as to define common liquid chambers.

Abstract: An inspection method includes: spectroscopically separating light from a predetermined imaging range of an inspection object into light of a plurality of wavelengths and imaging spectroscopic images of each of the wavelengths; inspecting a shape of the inspection object using the spectroscopic image of a predetermined wavelength among the wavelengths imaged in the imaging of the spectroscopic images of each of the wavelengths; and inspecting a color of the inspection object using the spectroscopic images of each of the wavelengths imaged. The predetermined wavelength is determined so that a maximum light quantity of the light from the inspection object in the corresponding spectroscopic image at the predetermined wavelength is equal to or higher than maximum light quantities in the other spectroscopic images at the other wavelengths.

Abstract: An optical module includes: a measuring device including a measuring portion that measures light reflected at a measurement position of a measurement target, a light source that radiates light onto the measurement position in a direction crossing a measurement optical axis oriented from the measurement position to the measuring portion, and a window through which light incident on the measuring portion passes; and a shutter that opens and closes the window of the measuring device. The shutter is provided with a reference object disposed closer to the measuring portion side than the measurement position on the measurement optical axis, on a face of the shutter facing the measuring portion when closing the window, and the optical module includes a light guide that guides the light from the light source to the reference object when the window is closed by the shutter.
