  • Patent number: 9804029
    Abstract: With a microspectroscopy device provided with an objective lens with a high numerical aperture, a defocus arises from thermal drift, etc., necessitating auto-focusing. Conventional auto-focus based on through-focus image acquisition takes time, and thus, it cannot be applied to continuous measurement over a long time wherein high-speed sampling is carried out. The present invention addresses this problem by having a defocus-sensing beam that has either defocus or astigmatism fall incident on the objective lens. Since how the image of the spot of the beam for defocus sensing blurs differs depending on the orientation of the defocus, real-time detection of the amount and orientation of defocus becomes possible, and high-speed realtime auto-focus becomes possible.

  • Patent number: 9463652
    Abstract: On a sheet of paper on which an image has already been formed, a first registration mark pair and a second registration mark pair are printed. The first registration mark pair and second registration mark pair each consist of a pair of registration marks that are arranged to be spaced apart in a paper-width direction, the second registration mark pair located posterior to the first registration mark pair in the paper-conveying direction. Based on the actual positional relationship between the first registration mark pair and the second registration mark pair that are read by a reading unit, a correction unit corrects discharge data that corresponds to an image formation area located between the first registration mark pair and the second registration mark pair.
