MULTIPLE OPTIC-AXIAL PHOTOELECTRIC SENSOR

PROBLEM TO BE SOLVED: To provide a multiple optic-axial photoelectric sensor which can more precisely perform optical axis adjustment work at least in an element arranging direction of a projector and a light receiver.SOLUTION: Three projection elements 12b, 12i, and 12o in a plurality of projection elements 12a to 12p are set to be optical axis adjusting projection elements. Light receiving elements 22b, 22i, and 22o confronting the projection elements 12b, 12i, and 12o and light receiving elements 22a, 22c, 22h, 22j, 22n, and 22p adjacent to the confronting light receiving elements 22b, 22i, and 22o include a CPU as numeric value output means outputting a light reception amount of received light from the projection elements 12b, 12i, and 12o as numerical value information. The sensor includes display units 31a to 31c for numerically displaying the numeric value information outputted from the CPU.
