Abstract

PURPOSE:To obtain a miniaturized, simplified device free from influences of dust, etc., by controlling the movement of a movable member by detecting and digitizing the acceleration of the movable member. CONSTITUTION:An acceleration signal S1 detected by an acceleration detector 8 fitted to a movable member is A/D-converted 9 and supplied to an adder 10. The adder 10 adds the digital value S2 of the signal S1 to the set value S3 of a register 11. The sum is set in the register 11 with a sampling clock (SC) to hold speed information obtained integrating the acceleration. The speed information is supplied to an adder 12, which adds it to the set value S4 of a register 13 to set the sum in the register 13 with the signal SC, holding the displacement position of the movable member which is the integral value of the speed. When this held value goes beyond a prescribed value, an overflow pulse S5 is outputted to a one-shot circuit 14 and a PLL circuit 15. The circuit operates a driving motor 6 through a motor driving circuit 18 on the basis of a phase difference signal between the pulse S5 and a command pulse CP.
