Abstract

PROBLEM TO BE SOLVED: To obtain an optical inclination sensor in which the centers of a light emitting element and a light receiving element can be aligned with the optical axis of a lens, an ideal parallel light, i.e., a sharp beam, can be obtained at a light projecting section, a spot being focused at a light receiving section has clear profile, a light shielding wall having sufficient height can be formed and noise light can be reduced. SOLUTION: Since a light projecting section 6 and a light receiving section 7 are provided with lenses 5a independently, optical centers of a light emitting element and a light receiving element can be aligned with the optical axis of the lenses. Consequently, an ideal parallel light is emitted from the light emitting element and the spot of reflected light from an object being formed on the light emitting element has clear profile. When an LED having an window in the center of emission and an electrode formed on the outer circumference of the window is employed as a light emitting element, the size of the light emitting source can be reduced and the focal length of the lens can be shortened resulting in a small size product emitting ideal light.
