Abstract
PURPOSE:To avoid the count mistake before and after the inversion, by respectively providing two FFs which take the output signal of one sensor as an input signal, the inverting signal of an output signal as a clear signal and the output signal of another seonsor as a clock pulse, in a counting circuit counting the number of revolutions of a rotating body. CONSTITUTION:The revolution of a rotating body 1 is detected with the 1st and 2nd rotating sensors S1, S2, and the results are respectively wave-shaped at the 1st and 2nd wave shaping circuits 2, 3. Further, the output (a) of the 1st wave shaping circuit 2 is taken as an input signal to an FF4 and as a clock pulse to an FF5, and the inverting output (c) of the output (a) is taken as a clear signal to the FF4. Similarly, the output (b) of the 2nd wave shaping circuit 3 is taken as an input signal to an FF5 and as a clock pulse to the FF4, and also the inverting output (d) of the output (b) is taken as a clear signal to the FF5. Further, the output signal of both the FFs 4, 5 count the difference between forward and reverse number of revolutions of the rotating body 1.
