    Abstract: 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.

    Abstract: In a system for scanning a document (43), a light source (22) illuminates the document; an imager (24, 41, 41', 61, 62) receives light from the document and directs it toward a detector array (25) which produces a corresponding array of electrical signals. The imager has several optical properties that are useful either individually or in combination. The imager is telecentric and thereby ensures that image size and magnification are insensitive to object displacement along the optical axis (46, 46') and image brightness is uniform independent of object off-axis distance. An aspheric element (33) within the imager balances focus variation (82-81-83) within the depth of field with spherical aberration and thereby provide nearly uniform image resolution. A diffraction pattern (33'), carried by the imager, corrects for spectral dispersion which occurs when light passes (63) from air into a refractive material (61, 62). An imager with a reflecting surface (32, 33) provides a system that is subject to little or no chromatic aberration. A solid imager (61, 62) with multiple internal reflecting surfaces (32, 33, 42) in optical series (32-33-32-42), configured to include the previously mentioned optical properties, also provides for highly stable alignment of reflecting surfaces.

    Abstract: To provide an optical scanning actuator that is capable of realizing widening of a light scanning angle and is excellent in durability, the optical scanning actuator includes a movable unit that supports an optical element, a plurality of leaf springs having a thin plate shape with one end portion being fixed and another end portion being attached to the movable unit, and an electromagnetic driving unit including a magnet, a yoke laminated on the magnet to form a closed magnetic circuit together with the magnet, and a coil held by the movable unit. The coil is positioned in a gap between the magnet and the yoke such that opening plane of the coil is substantially orthogonal to a laminating direction of the magnet and the yoke. The movable unit is driven by an electromagnetic force applied to the coil.
