  • Patent number: 9052390
    Abstract: Three light emitting elements and one light receiving element are provided on a surface of a substrate. The light receiving element is disposed within a first triangular region connecting the three light emitting elements. A first rectangle circumscribed around the triangular region is formed. In addition, a second rectangle circumscribed around a second triangle formed when intersections of a virtually set XY plane and optical axes of light beams emitted from the three light emitting elements are perpendicularly projected on the surface of the substrate, is formed. Directions of the light emitted from the three light emitting elements are set such that at least either one of length and breadth dimensions of the second rectangle is larger than a corresponding one of length and breadth dimensions of the first rectangle.
    Type: Grant
