摘要：
A detection sensor to detect a receiving position of laser light according to the present invention includes a pair of light receiving element arrays (11X and 11Y), wherein adjacent light receiving elements (PDXi) are positioned as spaced equidistantly from one another and are mutually connected via a resistor (RXj), and wherein the output lines (11a and 11b) are respectively connected to the light receiving elements that are present at both ends of the respective light receiving element arrays (11X and 11Y). The light receiving element arrays (11X and 11Y) configure a composite array wherein the light receiving elements of a first light receiving element array are respectively positioned between the mutually adjacent light receiving elements of a second light receiving element array. When the laser beam makes contact with any of the light receiving elements, an analysis arithmetic device derives the position whereupon the laser beam is received, by performing a computation in accordance with the output that is obtained from each respective output line.
