Claim 9:
10. The proximity detection device according to claim 9, wherein
the sensitivity setting unit calculates a center of gravity of an intensity distribution, obtained using coordinates of the intensities of beams of reflected light of infrared light detected by the light detector as ordered elements in an array along the first direction of the infrared light sources having emitted the infrared light, as a value indicating the first-direction position, and calculates a center of gravity of the intensity distribution, obtained using coordinates of the intensities of beams of reflected light of infrared light detected by the light detector as ordered elements in an array along the second direction of the infrared light sources having emitted the infrared light, as a value indicating the second-direction position.
