    摘要： A nozzle testing device includes: a two-dimensional image sensor to capture an image of a pattern formed on a recording object by discharging ink from a nozzle row while moving the nozzle row and the recording object relative to each other in a direction orthogonal to the nozzle row; a light source unit provided such that regularly reflected light by the pattern forms a regular reflection area in the image of the pattern captured by the two-dimensional image sensor; and a detection unit to analyze the image to detect discharge failure of the nozzles. The regular reflection area is formed in the image such that a dimension in a direction corresponding to the direction of relative movement between the nozzle row and the recording object is greater than a dimension in a direction orthogonal to the direction corresponding to the direction of relative movement in the image.

    摘要： An imaging device includes: a sensor unit that is arranged at a predetermined position inside a casing, and that images a subject outside the casing through an opening portion, with a part of an imaging region, while imaging a reference chart with another part of the imaging region; and a light absorption member that is arranged in an optical path of light from a illumination light source toward a specular-reflection position from which specular-reflection light of the illumination light source is entered to the sensor unit, in the imaging range. The light absorption member has at least a first surface on which light from the illumination light source toward the specular-reflection position is irradiated, and a second surface that faces to the first surface, and reflected light that has been reflected on the first surface and then on the second surface is further directed toward the first surface.
