    摘要: A distance measuring apparatus measuring a distance to an object is disclosed. The apparatus includes a light projector projecting an irradiating light onto the object; a first receiver receiving and converting a reflected light into a received light signal; a second receiver adjacent to the light projecting unit, the second receiver receiving and converting the irradiating light into a reference signal, the second receiver being different from the first receiver; and a distance measuring unit measuring the distance based on a time. The distance measuring unit calculates an integrated waveform based on a reference waveform of the reference signal and a waveform of the received light signal, determines, based on the integrated waveform, a time from projection of the irradiating light onto the object by the light projecting unit until reception of the reflected light by the first receiver, and calculates the distance based on the determined time.

    摘要: A light irradiator including multiple point light sources arranged in a straight line, a light-transmissive light guiding member provided in front of the point light sources in an emission direction of beams of light emitted from the point light sources, the light guiding member guiding the beams of light in a predetermined direction toward a surface to be irradiated; and two or more protrusions protruding toward the point light sources, provided on a light entering surface of the light guiding member and arranged in the same direction as the point light sources. The light guiding member and the point light sources are positioned such that a distance between the protrusions provided to the light guiding member and irradiation surfaces of the point light sources is equal at two positions.
