摘要： A multi-beam generating device has plural semiconductor lasers, optical fibers to propagate laser beams generated by the semiconductor lasers, an optical fiber array to propagate the laser beams passed through the optical fibers, and an optical waveguide device provided with waveguides to propagate the laser beams having passed through the optical fiber array. Each of the waveguides has a core layer and a clad layer; a pitch between adjacent waveguides in the arrangement is narrower on the output section side where the laser beams emit than on the input section side where the laser beams enter; a width of the core layer is narrower in the transverse direction that is the direction of the arrangement of the waveguides than in the vertical direction; and a difference in refractive index between the core layer and the clad layer is larger in the transverse direction than in the vertical direction.

摘要： An optical scanning device includes a pre-deflection optical system including a first optical element that adjusts the shape of beams emitted from the light source; and a second and third optical elements arranged such that the second optical element is arranged closer to the light source than the third optical element is. Both of the second and third optical elements have no refracting power in the deflection scanning direction and have positive refracting power only in a direction perpendicular to the deflection scanning direction. An interval between scanning lines formed on the scanned area and a deviation of the scanning-line interval between scanning positions are adjusted by displacement of the second and third optical elements in a direction of an optical axis of the pre-deflection optical system and displacement of at least one of the second and third optical elements in the direction perpendicular to the deflection scanning direction.

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.
