Abstract
A FIG. 1 is taken by a camera having optical/electrical elements arrayed in matrix, signals of pixels of the picture taken by the camera 2 are converted into binary data in a binary circuit 11, and the binary data is temporarily stored in a binary data storage device 12. The reference point 0 is determined on the edge of the figure, and radius L of the circuit scanning line 21 is determined based on the shape of the figure, and reference point 0 and the radius L of the circle scanning line 21 are inputted through an input unit 13. Coordinate data of pixels on the circuit scanning line 21 is operated based on the inputted numeric values in an arithmetic circuit 15. Binary data on pixels corresponding to coordinate data are read in the detector 16. When the pixel corresponding to the edge of the FIG. 1 is detected, a vector directed from the reference point 0 to the pixel is decided, and first and second drives 7, 8 are driven according to the vector.
