摘要： An image reading device including: concave first lens mirrors that are arranged in an array shape along a main scanning direction and that collimate scattered light reflected by an irradiated object and reflect the scattered light as a substantially parallel bundle of rays that are angled in a sub-scanning direction; planar mirrors that reflect light from the first lens mirrors; apertures that are arranged in an array shape and that allow light from the planar mirrors to pass through by way of openings that are arranged in an array shape and that are light-shielded therearound for selectively allowing light to pass through; concave second lens mirrors that are arranged in an array shape into which light from the apertures is incident and that reflect the light from the apertures as converged light; and light receivers that have light receiving areas on which light from the second lens mirrors is incident and that form images that correspond to light from the openings.

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： An optical scanner includes a light source for projecting a light beam, a deflector for deflecting the light beam, a reflective member for reflecting the light beam toward a target, a contact member, and a pressing member. The reflective member includes a reflective plane and a rear plane opposite the reflective plane. The contact member contacts one of the rear plane of the reflective member and a first lateral plane perpendicular to the reflective plane to position the reflective member in place. The pressing member presses the reflective member against the contact member and includes a first pressing portion to press the reflective plane of the reflective member and a second pressing portion to press a ridge of the reflective member at which the reflective plane and a second lateral plane opposite the first lateral plane and perpendicular to the reflective plane of the reflective member meet.

摘要： A technique is provided which can improve optical characteristics by suppressing the occurrence of an error in attachment of a rotary deflector that deflects a light flux from a light source and scans it in a main scanning direction. There are provided a rotary deflector that deflects the light flux from the light source and scans it in the main scanning direction, an imaging optical system that images the light flux scanned by the rotary deflector onto a specified scanning object, a support part that supports the rotary deflector rotatably, and a positioning part that comes in contact with the support part at plural contact positions and positions the support part, in which a shortest distance between the plural contact positions in an optical axis direction of the imaging optical system is longer than a shortest distance between the plural contact positions in the main scanning direction.
