Abstract: PURPOSE: To detect position data with simple, inexpensive constitution, by operating the count value of a transfer clock of a pattern on an array of photodetecting elements by storing a memory with a carry signal, generated every time when the count value reaches a prescribed value, as a write signal.  
     CONSTITUTION: An image by a photodetector 2 and a splitting prims 1 is projected on the photodetecting element array of an image pickup device 15 through a lens 14. Its time series picture signal is sent through a binary-coding circuit 16 to a counter 17, which outputs a carry signal to a counter 22 every time when its count value reaches a prescribed value. The X and Y clock pulses of the image pickup device 15 are sent to X and Y counters 18 and 19 respectively, and then counted. In this case, the Y clock pulse and a frame clock pulse are sent as reset pulses to the X and Y counters 18 and 19, whose count values are stored in memories 20 and 21 through the signals of counters 17 and 22. Then, a positioning mark is detected and positioned through a control circuit 23 and a driving circuit 11. Thus, position data is detected accurately with the simple, inexpensive constitution.
