置。[Scope of claim for utility model registration] Phase A and B detected by a rotary encoder
In a speed detection circuit device that outputs the rotation direction and its rotation speed as an analog signal of positive and negative polarity based on each phase pulse, an F/V outputs a voltage proportional to the number of forward rotation pulses or reverse rotation pulses that arrive. a converter, a flip-flop circuit that outputs a forward/reverse discrimination signal in response to the arrival of forward rotation pulses and reverse rotation pulses, and inputs the converted voltage from the F/V converter,
And the output side is wired via each diode.
It includes two inverting amplifiers and two non-inverting amplifiers that are OR-connected, and when the flip-flop circuit outputs a positive discrimination signal, it outputs the amplified signal of the inverting amplifier, and the flip-flop circuit outputs the amplified signal of the inverting amplifier, and the flip-flop circuit outputs the inverse discrimination signal. A speed detection circuit device comprising: an output selection circuit that outputs an amplified signal of an inverting amplifier when outputting the signal.
