As disclosed in Japanese Patent Publication No. 83, the apparatus measures how much the fiber direction of the paper is inclined with respect to the paper flow direction MD and the paper width direction CD. FIG. 5 is an explanatory diagram of a light spot on paper or a web, where the vertical axis represents the paper flow direction MD,
The horizontal axis is the paper width direction CD. A laser beam having a circular cross section is irradiated on paper or a web, and an elliptical reflected light appears.
This is because the reflectance is the lowest when the fiber direction and the optical axis direction are perpendicular to each other when the laser beam is reflected by paper, and when the laser beam is parallel, the laser beam is converted into band light using a slit and the correlation with the intensity of the measurement light is considered. Is because the reflectance is highest. Therefore, the direction in which the reflectance is highest is the fiber orientation direction.

角度が設計通り正確に装着できる。The light receiving element holding section 50 is integrally formed into a module by resin molding, metal casting, or the like. As a material, in the case of plastic, it is preferable to use a relatively heat-resistant nylon resin, polycarbonate, polyethylene terephthalate, polybutylene terephthalate, polyphenylene sulfide, or the like, and in the case of metal, a lightweight aluminum alloy or titanium alloy. Used, but inexpensive cast iron is acceptable. In this manner, when the module is integrally formed by resin molding, metal casting, or the like, the light receiving element mounting hole 54 is accurately molded, so that the arrangement angle of each light receiving element with respect to the optical axis can be accurately mounted as designed.

のギャップ長ｇ２との差の半分程度とする。 Δ＝（ｇ２−ｇ１）／２ (1)FIG. 3 is a sectional view of the fiber orientation meter with the spacer mounted. The spacer 70 is a ring-shaped disk, and is mounted between the sensor housing 40 and the flange 52.
The thickness Δ of the spacer 70 is equal to the first gap length g1 and the second gap length g1.
Is about half the difference from the gap length g2. Δ = (g2−g1) / 2 (1)

0, which is a wide value of the gap between the paper surface 30 and the lower sensor head 80. The paper surface 30 is a sensor housing 40 located on the upper side.
The general structure of a paper machine or a coating machine is to travel in a region sandwiched between the sensor head 80 and the lower sensor head 80.

Therefore, the gap between the paper surface 30 side of the sensor housing 40 and the lower sensor head 80 has a second gap length g2. In the embodiment shown in FIGS. 3 and 4, the spacer 70 is used.
Although the gap length g is adjusted depending on the presence or absence of the gap length, various thicknesses Δ may be prepared for the spacer 70 and may be selectively mounted according to the various gap lengths g. To show specific numerical values, if the first gap length g1 is 5 mm and the second gap length g2 is 10 mm, the spacer 70

じないという好ましい性質がある。In a reflection type optical sensor such as a fiber orientation meter in which the optical axis does not enter and reflect perpendicular to the paper surface 30, the optical path changes as the gap length g changes. This is reflected as a difference between the optical properties and thus the measurement properties.
However, it is not desirable that the measurement characteristics differ with the change in the gap length g. It is also conceivable to prepare two series of products with the first gap length g1 and the second gap length g2. However, considering the man-hours required for product development and management, the cost is increased, which is not preferable. By responding by the thickness Δ of the spacer 70, the position on the paper surface and the light receiving element holding portion 50
There is a preferable property that the optical path becomes the same at the position and the measurement characteristic does not differ.

行える。As described above, according to the fiber orientation meter according to the first aspect, since each light receiving element is held in the integrated light receiving element holding section 50, the light is reflected at the same angle around the light source. A plurality of light receiving elements can be easily mounted on the surface in an accurate mounting posture. Therefore, as compared with the case where a bracket is formed for each individual light receiving element, the number of parts is reduced, the manufacturing cost is reduced, and the size and weight are reduced by plastic molding, and the mounting position varies. Therefore, there is an effect that the detection accuracy is improved. According to the second aspect, it is clarified that the integrated light receiving element holding portion 50 has the collar portion 52, the light receiving element mounting hole, and the lens mounting hole. Further, when the material of the integrated light receiving element holding portion 50 is nylon resin, the molding can be easily performed.

Therefore, there is a preferable property that the optical path is the same between the position on the paper surface and the position of the light receiving element holding unit 50, and there is no difference in the measurement characteristics. In addition, when the arrangement is made by the presence or absence of the spacer as in claim 5, the product series is simplified, and the manufacturing cost and the management cost are reduced.
