Abstract

PURPOSE:To provide stability and eliminate such an erroneous action as miscounting, etc., by making a proper adjustment of output wave shape of a sensor, and also by preparing a wave shape whose phase is properly deviated toward a rotating direction. CONSTITUTION:A signal put out from a sensor 4 is put into a peak value detecting circuit of a peak pulse generating circuit 7, and the maximum peak is put out as a fall of the signal. This fall is put into a single stabilizing circuit, and a negative pulse of a constant width is put into a clock terminal of a flip-flop 9 through an inverter. An output of the sensor 4 is put into a peak pulse generating circuit 8 through an inversion amplifier 6, and a pulse of a constant width which rises at the maximum peak of the inversion output is given to a reset terminal of the flip- flop 9. An output of the flip-flop 9 is put into a phase discriminating circuit 10. A flip-flop 9' generates a pulse whose phase is differed by 90 deg. toward the output of the flip-flop 9.
