<p>PROBLEM TO BE SOLVED: To reduce the cost of a product by making a universal module for composing a light transmission/reception part that is used for a photoelectric sensor system or the like. SOLUTION: A module 1 has its appearance in nearly cubic shape, are mounted to a module base 2 so that the light reception axis of a photo IC 3 for composing a light reception part faces upward, and are covered with a resin cover 5 that is composed of a light transmissive material. Electrode parts with the same function are arranged at the bottom and rear surfaces of the module 1, thus selectively connecting two orthogonal surfaces for a circuit substrate and selectively using the module 1 in a horizontal or vertical state appropriately.</p> |
