Abstract

PURPOSE: To obtain a miniature device which display fine extent of movement with high precision and also detects the direction of the movement, by providing a variable capacity type encoder and a digital signal processing circuit.
CONSTITUTION: Fixed plate 4 having a conductive pattern for forming capacitors C1WC4, and rotary disk 5 having 18 radial conductive patterns are arranged coaxially opposing to each other to form a variable capacity encoder. This encoder is applied with clock signal VIN. Outputs VOUT1 and VOUT2 having a π/2 phase difference corresponding to the rotation of rotary disk 5 are passed through comparators 23 and 24 to send outputs of higher than a prescribed level. The outputs are applied to terminals D1 and D2 of FFs 25 and 26. Clock signal VIN, on the other hand, is inputted to terminals T1 and T2 of FFs 25 and 26 via delay circuit 27 and a counter counts the numbers of leading edges and trailing edges of outputs V01 and V02, so that the rotary extent of rotary disk 5 is digitally displayed with high precision. Its output is passed through FF30 to send rotation direction signal V0 out.
