In the apparatus for measuring the optical characteristics of the object to be measured, a backing plate, which is a reference plate made of two colors, is provided in the detection section on the back side of the object to be irradiated with the light. When detecting and measuring the reflected light affected by the backing plate, in a certain area of the surface of the housing at the upper position of the backing plate, the flat part of the part of the certain area is lower than the surface position of other housings. An air purge port is provided on the side wall surface of the formed object running inlet, and an air outlet for guiding the air ejected from the air purge port is formed on the measured object running exit side. a transparent member disposed above the backing plate in the recess so that only one of the two colors can be seen as the backing plate moves, and in a state where there is no difference in level from the plane position of the recess. a window portion; during measurement of the object to be measured, the surface is stored in a state with no difference in level from the planar position of the recess, and when the object is not being measured, the surface to be cleaned is raised to the planar position of the recess by a lifting mechanism; An optical characteristic measuring device characterized by using a structure comprising: a window cleaning mechanism whose upper part rotates and which can be stored in its original position after the rotation is completed. (2) Light is irradiated from one of the detection sections to the object to be measured, which travels in a fixed direction between the detection sections provided above and below, and the reflected light is detected to detect the optical characteristics of the object to be measured. In an apparatus for measuring characteristics, Gunn diodes for generating and receiving microwaves, a receiving circuit for receiving signals from the Gunn diodes, and a driving circuit for driving the Gunn diodes are provided in the upper and lower detection sections, and various types of An optical characteristic measuring device characterized in that signals are transmitted and received between the upper and lower detection sections, which are related to the operation of the mechanism and the cooperative operation of each section, using Gunn diodes or drive circuits. (3) Light is irradiated from one of the detection units to the object to be measured, which travels in a certain direction between the detection units provided above and below, and the reflected light is detected to detect the optical characteristics of the object to be measured. In an apparatus for measuring characteristics, when a dirt compensation reference plate is provided on one side of the upper and lower detection units, the reference plate is provided in the detection unit on the same side or on the opposite side of the dirt compensation reference plate. In order to monitor contamination, a reference plate having a monitor color different from that of the reference plate for contamination compensation is provided, and contamination compensation is achieved by adjusting the degree of contamination based on the difference in color.
