    摘要: An image capturing device includes an image capturing unit, a moving unit, a detector, and a determiner. The image capturing unit includes an optical transmission member; and a sensor capturing an image of the subject via the optical transmission member. The moving unit moves the image capturing unit in an optical axis direction of the sensor. The detector detects a contamination from first and second images. The first and second images are captured by the sensor when the image capturing unit is located at first and second positions in the optical axis direction, respectively. The second position is spaced away from the subject than the first position in the optical axis direction. The determiner determines that a contamination is deposited on the optical transmission member when a difference in the number of pixels in which a contamination is detected between the first and second images is less than a threshold.

    摘要: An image scanning device includes a base part; and multiple image sensors each including a substrate, a line sensor including scanning elements arranged on the substrate, and a holder for holding the substrate. The base part holds the image sensors such that the scanning elements of an image sensor partly overlap the scanning elements of an adjacent image sensor in the main-scanning direction. The coefficients of linear expansion of the substrate and the base part are substantially the same; the holder and the base part are fixed together at a first fixing point; the holder and the substrate are fixed together at a second fixing point; and the distance in the main-scanning direction between the first fixing point and the second fixing point and the direction of the second fixing point with respect to the first fixing point are the same for all the image sensors.

    摘要: A recording apparatus includes a carriage; a first head group including a recording head and disposed on the carriage; and a second head group including a recording head and disposed on the carriage adjacent the first head group in a staggered manner with respect to a sub-scan direction. The carriage is configured to move in a main scan direction in order to record an image on a recording medium. The recording apparatus further includes a forming unit configured to form plural test patterns including a first pattern formed by the recording head of the first head group and a second pattern formed by the recording head of the second head group. The test patterns are spaced apart from one another in the sub-scan direction. The position of the second pattern relative to the first pattern in the sub-scan direction is varied successively from one test pattern to another.
