る紙の光学的特性測定装置。 An upper detection section and a lower detection section are arranged opposite to each other with a sheet of paper in between, the upper detection section detects the reflected light of the light irradiated onto the paper surface at a predetermined angle of incidence, and the lower detection section A rotating disk whose surface is divided into two parts, black and white, is rotated, and the reflected light detected when the paper is backed with the black part of the rotating disk and the reflected light is detected when the paper is backed with the white part. In the apparatus for measuring the optical characteristics of the paper from the relationship with the detected reflected light, the surface of the rotating disk is coated with a transparent protective film, the surface of the rotating disk is formed into a spiral shape, and the center thereof is aligned with the center of the rotating disk. A brush whose line direction away from the center of the spiral coincides with the direction of rotation of the rotating disk is brought into contact with the rotating disk at a position away from the measurement optical path. Device.
