IPC: G01B21/00
Filed: 1979-05-04
Abstract: PURPOSE: To prevent wrong position detection due to minute reciprocation, by generating clock signals for addition and substraction synchronously with the rising and falling of one of two-phase square-wave signals from a rotational position pulse generator and counting the clock signals.  
     CONSTITUTION: Square-wave signals A, B, which are produced by a rotational position pulse generator with a phase difference of 90° depending on the direction of rotation, are applied to a gate circuit. In forward rotation, the level of the signal B becomes zero at the time of falling of the other signal B and the output pulse of a monostable circuit 20 is used as a clock signal P 1 . At the time of falling of the signal A, the level of the signal B is "1" and the output pulse of another monostable circuit 21 is picked out as the clock signal P 1 . The clock signal P 1  is applied for addition in a reversible counter. In reverse rotation, the relation between the signals A, B is inverted and a clock signal P 2  for subtraction is picked out. When a rotating body performs minute vibration, equal numbers of clock signals P 1 , P 2  are produced not to change the content of the reversible counter.
