Abstract
An object of the present invention is to provide a position detecting device using a reflection type photosensor, which assures a small size and low cost and enables detection of a long distance of about 10 mm or more, and a position detecting method. The position of a moving body is detected by providing, on the moving body, a reflection plate () having reflecting surfaces (sa) and non-reflecting surfaces (sb) arranged alternately in a moving direction of the moving body, providing a light receiving element () of the reflection type photosensor () with, for example, two light receiving portions (and) having different light receiving regions in the moving direction of the moving body, outputting output signals from these two light receiving portions (and), and carrying out at least one calculation of adding, subtracting, dividing and function calculation of these two output signals.
