    摘要： In a scanning optical system where a bundle of rays scans a surface to be scanned through an optical deflector and an image forming optical system, the image forming optical system includes a positive front lens group having two lens elements and a rear lens group constituted by an elongated single anamorphic lens element having a strong positive refractive power in the sub scanning direction. All the lens elements in the image forming optical system are made of a resin material, and the scanning optical system satisfies the conditions: (1)d.sub.0 /f

    摘要： A rotation detector includes a first distance sensor disposed to face a rotating body with a gear portion formed non-parallel to a rotation axis for continuously measuring a distance from the gear portion during rotation of the rotating body, a second distance sensor disposed at a position different from the first distance sensor in a direction of the rotation axis for continuously measuring a distance from the gear portion during rotation of the rotating body, and an axis shift detecting portion for detecting an axis shift of the rotation axis based on a variation in the distance measured by at least one of the first and second distance sensors.

    摘要： There is provided an optical system for an optical disc which requires a numerical aperture larger than or equal to 0.60. The optical system is provided with a light source, an objective lens, and a driving system that controls a position and an attitude of the objective lens. The driving system operates to move the objective lens in a direction perpendicular to a central axis of the objective lens for a tracking operation, and to change the attitude of the objective lens during the tracking operation so that the central axis on a light source side tilts toward the light source.

    摘要： When bonding a workpiece to a substrate, processed parts of the substrate and the workpiece are observed and behavior such as the production of voids and the flowing of resin is observed. An apparatus for observing an assembled state of components includes: a stage on which a substrate is set; a head mechanism that bonds, by applying heat and pressure, an observation workpiece made of a transparent material to the substrate via resin supplied between the substrate and the observation workpiece; a light source that irradiates an observed part of the substrate and the observation workpiece mounted on the stage with light; and a camera that takes, from the observation workpiece side, an image of the observed part when the observation workpiece is bonded to the substrate set on the stage.
