Title: Rotation detector
Inventor: SAKAMOTO KIYOSHI
IPC: G01P3/481
Filed: 1989-09-29
Abstract: PURPOSE:To make it possible to detect rotation so that the effect of noise is decreased by reversing the level of an output in response to the comparison of a signal level and a preset level. CONSTITUTION:In a sensor part 2, the change in magnetic flux due to the approach and separation of a projecting part 10 in the rotation of a rotary body 1 is transduced into an AC voltage. In a waveform shaping part 3, the AC voltage from the sensor part 2 is shaped into the pulse waveform. A rotation detecting part 4 counts the number of pulses per unit time and detects the rotating speed. At this time, the signal level from the sensor part 2 is compared with a preset level in a comparator 31 of the waveform shaping part 3. When the signal level exceeds the preset level, the preset level is biased negatively for a specified period and the low level signal is outputted. When the signal level becomes lower than the preset level, the preset level is biased positively for the specified period, and the high signal is outputted. After the specified period, the negative or positive bias is released. In this way, the output of the erroneous pulses caused by noises is prevented. Even if the signal level becomes low at the low speed, the rotating speed can be detected positively.
