    摘要: Disclosed is an optical scanning device including a light source including multiple light-emitting elements, the multiple light-emitting elements being arranged in a linear manner, a collimator lens to collimate a light beam from the light source, a light-deflecting device to deflect a light beam having passed through the collimator lens to a medium to be scanned and scan the medium with the light beam, and a rear optical system arranged in an optical path between the collimator lens and the medium to be scanned, wherein the collimator lens deviates an image surface in a direction opposite to an image surface deviation on the medium to be scanned by a nearly same amount as the image surface deviation, the image surface deviation being caused by a change of an image height of the light source, and the change being caused by the rear optical system.

    摘要: An optical scanning device including a light source having multiple light emitters; an optical element to reflect and transmit the emitted light beams; a photodetector to receive the reflected light beams; an aperture having an opening to shape the transmitted light beams; a light deflector to deflect the transmitted light beams; and a scanning optics to guide the deflected light beams to a scanning surface. The quantity of each of the light beams received by the photodetector is not less than 0.01 mW, and the size of a light receiving surface of the photodetector is determined such that even when the full width at half maximum of the emitted light beams changes, the rate of change of the ratio of the quantity of the light beams detected by the photodetector to the quantity of the light beams passing through the opening of the aperture is not greater than 4%.

    摘要: A disclosed light source apparatus includes a light source including multiple light emitting devices; an optical element configured to transmit light emitted from the light source; a tube configured to hold the optical element; and a tube holder configured to fix the tube by holding an end of the tube close to the light source or by holding the end of the tube on the light emission side away from the light source. A positional displacement preventing member is provided at the other end of the tube on a light emission side away from the light source in such a manner as to be slidable on the tube in the direction of an optical axis and prevent positional displacement of the tube in all directions perpendicular to the optical axis.
