摘要： Reflected light can be effectively utilized by increasing a light receiving area. Incremental light receiving element groups 140L and 140R are separated and arranged in the circumferential direction of a rotating disc 110 while placing a light source 130 therebetween. First and second absolute light receiving element groups 150D and 150U are arranged at both sides of the outside and inside of the light source 130 in the radial direction of the rotating disc 110. As a result, first and second absolute light receiving elements 151 and 152 are continuously arranged, and also the incremental light receiving element groups 140L and 140R and the absolute light receiving element groups 150D and 150U can be arranged to surround the periphery of the light source 130 from four directions.

摘要： An angle detecting device with a self-calibration function is also provided with an axis run-out measuring function, so that various kinds of setups to an engine, a drive shaft of an automobile, and the like, can be made readily. The angle detecting device with the self-calibration function is used, in which a plurality of sensor heads is provided with an equiangular interval at a circumference of a scale disc fixed to a rotating shaft, and when one of the sensor heads is selected as a reference sensor head, a sum of measurement differences between the reference sensor head and the other respective sensor heads, and this sum is divided by the number of sensor heads, to determine an average value, whereby a self-calibration value is obtained. Further, a sensor head selected as the reference sensor head is changed to another sensor head in order, and each of the self-calibration values for all the sensor heads is obtained where each of all the sensor heads is adopted as the reference head. Then, each of the self-calibration values is deviated by an angle in terms of arrangement with respect to a particular sensor head, and a phase is aligned to a self-calibration value where the particular sensor head is adopted as the reference head. Then, an average value for all the calculation results of the phase converting is obtained, and the average value is subtracted from each of the calculation results having been subjected to the phase conversion, to obtain only asynchronous angular errors.
