    • An optical sensor is provided to set or adjust a sensitivity thereof freely with a high accuracy. In an optical sensor, a light receiving element(20) is arranged in a housing(10). An outer filter(50) is rotatably mounted on an attachment side of the housing. A lightproof member(40) rotates in accordance with a rotation of the outer filter for adjusting an intensity of light, incident on a light receiving side of the light receiving element. The lightproof member includes a rotary shaft fixed at a central part thereof and an illumination device adjusting quantities of the light, incident on the light receiving side of the light receiving element within a range of a rotation direction of the rotary shaft.
    • 提供光学传感器以高精度自由设定或调节其灵敏度。 在光学传感器中,光接收元件(20)布置在壳体(10)中。 外部过滤器(50)可旋转地安装在壳体的附接侧上。 防光构件(40)根据外部过滤器的旋转而旋转,用于调节入射在光接收元件的光接收侧的光的强度。 防光构件包括固定在其中心部分的旋转轴和照明装置,其在旋转轴的旋转方向的范围内调节入射在光接收元件的光接收侧的光量。
