とを備えてなることを特徴とする指針位置検出装置。A beam-shaped detection light is disposed on the front side of the instrument display section 1 consisting of a dial 11 and a pointer 12 that rotates at an interval above the dial and on the extension line of the pointer shaft, and emits a beam-like detection light along the rotation locus drawn by the tip of the pointer 12. The light receiving section 23 receives a real image of the irradiation part P at the tip of the pointer 12, which is brightly illuminated by the beam-like detection light, and the beam-like detection light illuminates the pointer 12. a photodetector 2 that detects that the beam-shaped detection light is irradiated; and a rotational position detector 5 that detects the rotational position of the beam-shaped detection light by detecting the rotational drive position of a drive mechanism 40 that rotates the beam-shaped detection light.
, the output signal of the photodetector 2 and the rotational position detector 5
an arithmetic circuit 6 which receives the output signal of the pointer 12 and calculates the rotational position of the pointer 12 by detecting the rotational position of the beam-like detection light when the pointer 12 is irradiated with the beam-like detection light;
