PURPOSE:To provide a magnetic rotary encoder where the cost for the encoder can be reduced, and no synchronous deviation between the zero point signal and the magnetic pole signal is present. CONSTITUTION:In a magnetic rotary encoder to provide the multi-phase magnetic pole signal synchronous with the pulse signal of A and B phases and the pulse signal of Z-phase (zero point), two phase signals of the magnetic pole signal is received by AND circuits 21-23, one-shot multivibrators 24-26 are driven by the output of the AND circuits to generate the zero point pulse signal where one-phase rise or fall of two phase magnetic pole signals is synchronized. |
