摘要： In a first scanning lens (60), a first lens section (60Y) and a second lens section (60C) are vertically overlapped in such a manner as to separate lens centers thereof by a first distance. In a second scanning lens (61), a third lens section (61M) and a fourth lens section (61Bk) are vertically overlapped in such a manner as to separate lens centers thereof by a second distance equal to the first distance. A vertical positional relationship of the first lens section (60Y) with the second lens section (60C) is the same as a vertical positional relationship of the third lens section (61M) with the fourth lens section (61Bk). Further, a separating direction of a lens center of the first lens section (60Y) from that of the second lens section (60C) is opposite to a separating direction of a lens center of the third lens section (61M) from that of the fourth lens section (61Bk).

摘要： A system includes a laser scanner system. The system includes a scanner laser to generate an optical scanning beam. The system also includes a spindle assembly comprising a spindle that extends along an axis and reflects the optical scanning beam. The system also includes a beam detector to receive the reflected optical scanning beam from the single facet and to indicate when to generate a latent image corresponding to an image based on the optical scanning beam for a given scan operation. The system further includes a scan controller to control the scanner laser such that the optical scanning beam is reflected from only a single facet of the spindle during the given scan operation.

摘要： A light scanning device (23) includes a polygon mirror (4), a first incidence optical system (5Y), a second incidence optical system (5C), a first scanning lens (6Y), and a second scanning lens (6C). The polygon mirror (4) includes a deflection surface (41) being adapted to ensure entering of the first light beam and the second light beam at an identical timing. Assuming that, at a time point, at which the light beam reflected at the deflection surface (41) passes through a position on an optical axis of a scanning lens (6Y, 6C) in plan view of the polygon mirror (41) along an axial direction of the rotation shaft (40), a reflection point of a light beam on the deflection surface (41) is a reference point (P), the second scanning lens (6C) is arranged at different positions in a main-scanning direction and in an optical axis direction with respect to the first scanning lens (6Y), such that a circle locus (A1) is along an offset curved line (A2). The circle locus (A1) is a locus of a point corresponding to the reference point (P) by the rotation of the polygon mirror (4).

摘要： An optical scanning device includes a scanning member (62), a plurality of light sources (611A-614A), a first reflection mirror (75), and a second reflection mirror (76). The scanning member (62) scans incident laser beams in a predetermined main scanning direction. The plurality of light sources (611A-614A) 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 (75) 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 (611A-614A). The second reflection mirror (76) 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 (75) toward the scanning member (62).
