Abstract
Disclosed is a method for detecting a position receiving a light beam by using optical fibers. One-side end face of a plurality of optical fibers are arranged in a line or plane. Each optical fiber is branched by a light beam splitter having a plurality of output ports. The branched optical fibers are bundled into groups. Each group of the bundled optical fibers is connected to a light beam detecting sensor which consists of one light beam detecting member for detecting a position receiving a laser beam. Therefore, a large number of light beam sensors are not needed. As a result, the accompanying electronic circuits can be simplified, and high speed processing without any delay is also permitted.
