とを特徴とする回転エンコーダ。In a rotary encoder that converts rotational speed and rotational position into electrical signals, only one of the multiple slits that is directly connected to the rotating shaft, rotates and rotates as the shaft rotates, and transmits light to the other slits. A rotating number plate that transmits a large amount of light compared to the above, a light emitting element that is fixed on a base that does not rotate and illuminates the number plate, and a light emitting element that is mounted on the base in the direction of light emission of the light emitting element. A fixing plate having a slit for controlling a fixed amount of light from the light emitting element, and a fixing plate arranged on the base so as to be on a straight line connecting the light emitting element, the slit in the fixing plate, and the slit in the rotation code plate. One light receiving element receives the light transmitted through the slit of the plate and the slit of the rotation code plate and outputs an electric signal proportional to the amount of incident light, and after receiving and amplifying the signal from the above light receiving element, It consists of a circuit that generates a pulse when a preset threshold value is exceeded, and a circuit that has a threshold higher than the threshold value of the above circuit. A rotary encoder characterized in that it simultaneously generates hail pulses.
