  • Patent number: 11347980
    Abstract: A positional-deviation correcting device includes a reading device and control circuitry. The reading device reads recording media on which marks and each of adjustment charts having different image densities are formed in accordance with the image densities. The control circuitry acquires data on image formation positions of the marks on the recording media, based on a reading result of the marks; and corrects an image formation position of an image to be formed on a recording medium. The control circuitry calculates a correction value of the image formation position corresponding to an image density for each of the image densities corresponding to the adjustment charts on a one-on-one relationship, based on a reading result of the adjustment charts; interpolates correction values corresponding to the image densities on a one-on-one relationship; and calculates a correction value of the image formation position corresponding to another image density different from the image densities.

  • Patent number: 10946640
    Abstract: A transfer apparatus includes a head unit (210C, 210K) to process an object (W) transferred in a transfer direction, a first support member disposed upstream in the transfer direction with respect to a process position to support the object, a second support member disposed downstream in the transfer direction of the process position to support the object, a surface detector between the first and second support members to detect first surface information of the object, an upstream surface detector disposed upstream in the transfer direction with respect to the surface detector to detect second surface information of the object, an edge detector disposed closer to the upstream surface detector than the surface detector in the transfer direction to detect an edge of the object, and a controller to move the head unit based on detection results of the surface detector and the upstream surface detector and a detection result of the edge detector.
