Abstract
A plurality of periodical signals are generated as the moving body moves. The periodical signals are given respective fundamental values. The fundamental value of one of the periodical signals that has a maximum value is detected sequentially. An extension value is generated in such a manner as to be incremented or decremented when the detected fundamental value changes from one unit repetition range to another. Position detection information of the moving body is constructed as a combination of the detected fundamental value and the extension value. The position detection information is stored.
