Abstract
A multiple ranging apparatus has a light emitting section constituted by a plurality of aligned LEDs which emit light rays of wavelengths different from one another, and a light receiving section constituted by a plurality of aligned PSD parts which have wavelength sensitivities corresponding to the different wavelengths of the light rays emitted from the LEDs. Thus, even when ranging of respective points is simultaneously measured in multiple ranging measurement, it is possible to identify which LED the light is emitted from, and therefore, to simultaneously measure the distances of two or more points.
