Filed: 1988-05-13
Abstract: PURPOSE:To enable the execution of accurate positioning without being affected by disturbance, by a method wherein a plurality of counting clock signals for operating a reversible counter are formed from two sensors disposed with their prescribed periodic phases shifted from each other. CONSTITUTION:Two light-sensing elements provided in a photo-interrupter generate signals phiA and phiB shifted in phase by 90 deg. from each other, for instance, and these signals are inputted to shift registers 80 and 81 through a comparator respectively. From AND gates 82-85, signals being synchronous with the respective leading and trailing edges of said signals are generated. In the case of a forward operation, D-FF 91-94 generate pulses which are formed by combination of these four signals and different in phase from one another, and do not generate signals in the case of a backward operation. Signals of the leading and trailing edges of each signal are inputted to an OR gate 90, and therefore four counting clock signals are obtained for a slit period. Even when the direction of movement is shifted and noise is generated, accordingly, an accurate positional information can be obtained without false counting, on condition that the position is within a prescribed range of a slit phase.
