Abstract
PURPOSE: To prevent occurrence of wrong collision detection, by detecting the amplitude of the output of a partial response (1, -1) filter with a peak detector and increasing the threshold voltage of a signal discriminator proportionally to the output voltage of the filter by means of a threshold voltage generating circuit when the output voltage exceeds a prescribed voltage.
CONSTITUTION: The output voltage of a peak detector 15 which detects the output amplitude of a partial response (1, -1) filter 13 corresponds to a light receiving electric power. Therefore, when the light receiving electric power is lower than the light receiving electric power corresponding to the prescribed voltage, a fixed threshold voltage is outputted to a signal discriminator 14 from a threshold voltage generating circuit 16 and, when the light receiving electric power exceeds the light receiving electric power corresponding to the prescribed voltage, a threshold voltage which is proportional to the rise of the light receiving electric power is outputted to the signal discriminator 14. Therefore, stable collision detecting operations can be obtained even in an area where the light receiving electric power is large.
