Abstract

PURPOSE: To obtain a high resolving power and prevent an erroneous operation in relation to chattering by utilizing the rise and fall of the output pulse of a rotary encoder.
CONSTITUTION: When pulse signals A and B with waveforms a and b are inputted, rise detecting parts 20 and 22 output pulse signals at the rise of the signals A and B as shown by waveforms c and e, while fall detecting parts 21 and 23 output pulse signals at the fall of the signals A and B as shown by waveforms d and f. As the result, pulse signals shown by waveforms g and h are obtained from the output terminals R and L of OR gates 32 and 33.
