Abstract: PURPOSE:To eliminate the influence of the change in the intensities of ambient light and reflected light by subjecting a detection signal to pulse forming by the use of a threshold value associating to the peak value of the detection signal in an photoelectric revolution detector. CONSTITUTION:The reflected light from a reflection plate attached to a rotator is converted to an electric signal by a photoelectric converter 3. When this signal is formed into a pulse waveform by a suitable threshold value, the pulse signal of the frequency proportional to the number of revolutions is obtained. At that time, in order to eliminate the influence or the like of the change in the intensity of the reflected light and ambient light, the signal past an amplifier 4 is detected in the peak value with a peak detector 7. With a value obtained by suitably dividing these with a voltage divider 8 as a threshold value, the signal is subjected to pulse forming with a comparator 5. These pulses are counted with a counter 6.
