Abstract:
An optical scanning device includes a first aperture and an adjustment mechanism. The first aperture includes a first opening portion and a first cut portion. The first opening portion restricts a beam path width of a laser beam emitted from a light source. A first blocking member that blocks the laser beam is inserted in a detachable manner in the first cut portion in a direction perpendicular to a longitudinal direction of the first opening portion, at a predetermined position of the first cut portion. The adjustment mechanism is configured to adjust a fixed state of the first aperture.
Abstract:
An optical scanning device includes a cylindrical aperture, a support member, and a base portion. In the aperture, an opening portion that restricts a beam path width of a laser beam emitted from a light source is formed. The support member includes a cylinder supporting portion that pivotably supports the aperture. To the base portion, the support member is fixed by adhesion fixing. The base portion includes a pass-through portion that passes through between front and rear surfaces of the base portion and allows the support member to move in direction perpendicular to a pivoting axis of the aperture. The support member has a length such that its lower end portion projects from a rear surface of the base portion in the state where the support member has been inserted in the pass-through portion to such a position where laser beam is incident in the opening portion of the aperture.
Abstract:
An optical scanning device includes a light source, a scanning member, a converging lens, a first aperture, a second aperture, and a support member. The first aperture is provided between the converging lens and the scanning member and includes a first opening portion configured to restrict a beam path width in a main scanning direction of the laser beams emitted from the light source. The second aperture is provided between the light source and the converging lens and includes a second opening portion and a cylindrical portion. The second opening portion is configured to restrict a beam path width in a sub scanning direction of the laser beams emitted from the light source, and is formed in the cylindrical portion. The support member includes a cylinder supporting portion that pivotably supports the cylindrical portion of the second aperture.
Abstract:
An optical scanning device includes a scanning member, a plurality of light sources, a first reflection mirror, and a second reflection mirror. The scanning member scans incident laser beams in a predetermined main scanning direction. The plurality of light sources emit the laser beams from positions that are different along a sub scanning direction that is perpendicular to an optical axis direction of the laser beams and the main scanning direction. The first reflection mirror is inclined around the main scanning direction as a rotation axis, is inclined around the sub scanning direction as another rotation axis, and reflects the laser beams emitted from the light sources. The second reflection mirror is inclined around the main scanning direction as a rotation axis, is inclined around the sub scanning direction as another rotation axis, and reflects the laser beams reflected by the first reflection mirror toward the scanning member.

Abstract:
A light scanning device includes a light source, a deflector, a reflection mirror, and a light width regulating portion. The light source includes a plurality of light-emitting elements located at intervals one another. The deflector deflects to scan by reflecting a plurality of light beams. The plurality of light beams are emitted from the respective light-emitting elements. The reflection mirror is located in an optical path between the light source and the deflector and guides the plurality of light beams emitted from the plurality of light-emitting elements to the deflector. The light width regulating portion regulates widths of the plurality of light beams reflected by the reflection mirror in a main-scanning direction. The light width regulating portion is located adjacent to a reflecting surface of the reflection mirror and includes a pair of regulating wall portions located opposed one another in the main-scanning direction.
Abstract:
Disclosed is an optical deflector including a polygonal mirror and a drive motor each mounted on a substrate, a cover member covering the polygonal mirror and the drive motor, and an electronic component. The cover member includes: a first cover portion defining a first space in which the polygonal mirror is installed, wherein the first cover portion is formed with a first opening opened in opposed relation to an outer peripheral surface of the polygonal mirror; and a second cover portion defining a second space which is communicated with the first space and in which the drive motor is installed, wherein the second cover portion is formed with a second opening opened in opposed relation to a motor body of the drive motor. When viewed in the first direction, the electronic component is disposed such that it falls within an open region of the second opening.
