    • There is provided an encoder in which the absolute angle can be detected with high accuracy even when the irradiated position of light to be detected with respect to a scale is displaced from a reference, and a photodetecting device for an encoder used for such an encoder.In the encoder 1, by passing light to be detected through a straight-line light transmitting portion 17, a bright portion 19 to which the light to be detected is irradiated is formed in an area of a scale plate 11 containing mutually separate parts of arranged lines L1 and L2 and also a dark portion 20 to which no light to be detected is irradiated is formed in the other area. Accordingly, a relative angle between light intensity peaks P1 and P2 (reference relative angle) can be uniquely calculated based on the shape of the light transmitting portion 17. Therefore, in the encoder 1, even if the irradiated position of the light to be detected with respect to the scale plate 11 is displaced from the reference, the absolute angle can be detected with high accuracy by calculating a deviation amount of a relative angle on detecting the angle from the reference relative angle as a corrected amount α°.
    • 提供了一种编码器,其中即使当相对于标尺的待检测的光的照射位置偏离基准时,也可以高精度地检测绝对角度,以及用于这种编码器的编码器的光电检测装置。 在编码器1中,通过使被检测光通过直线透光部17照射被检测光的亮部19形成在刻度板11的包含相互分离的部分的区域 在另一个区域中形成线L 1和L 2以及未被检测的光被照射的暗部20。 因此,可以基于透光部17的形状来唯一地计算光强度峰值P 1和P 2之间的相对角度(参考相对角度)。因此,在编码器1中,即使光的照射位置 相对于标尺板11被检测到的位置偏离基准,通过计算从基准相对角度检测角度的相对角度的偏差量作为校正量α°,可以高精度地检测绝对角度。
