する紙の光学的特性測定装置。 Light from a light source is intermittently irradiated onto the surface of the paper to be measured at a predetermined angle of incidence, and a standard plate made of two colors, white and black, is placed at a position parallel to the back side of the irradiation position of the paper. Signal processing that determines the color, opacity, and whiteness of the paper by installing the paper so that the color is on the paper, guiding the reflected light from the irradiated light to a sensor via an optical system, and performing predetermined processing using the detected signal. In a paper optical property measuring device comprising:
A color discrimination plate and a cutout plate are attached to the back surface of the standard plate, with the rotation center axis being the same as that of the standard plate, and at this time, the color discrimination plate has a semicircular shape and is attached to the white color of the standard plate. Alternatively, the cutout plate is assembled so as to overlap the black part and used for white/black discrimination, and the cutout plate is assembled so that half of the cutout plate overlaps the white and black parts of the standard plate to determine the readout timing of the sensor. An apparatus for measuring optical properties of paper, characterized in that it is used for determining.
