構成としたことを特徴とする回転角センサ。A slit plate having a plurality of optical slits and rotating with rotation of a rotation axis, a light emitting part provided at a position opposite to one surface of the slit plate, and a light emitting section opposite to the other surface of the slit plate. a light-receiving element having a light-receiving element that is provided at a position and receives the light emitted from the light-emitting part through the slit of the slit plate, and outputs a pulse signal by intermittent light passing through the slit; In a rotation angle sensor that detects a rotation angle by measuring the number of pulses of a pulse signal output from a light receiving element, a slit plate rotates 360 degrees (n is the number of slits) to attach the light receiving element to the light receiving part and is activated when raised. A plurality of slits are arranged so as to sequentially receive light passing through the same slit within the range of the trajectory of the slit, and the rotation angle is detected from each output signal output from the light receiving element. Angle sensor.
