摘要： In an optical scanner, an optical deflector has a deflecting reflecting face rotated at an equal speed. A light beam from a light source is deflected on a plane by the deflector at an equal angular velocity and is incident to a reflective image-forming element through a half mirror inclined with respect to a beam deflecting face. The light beam reflected on the reflective image-forming element is reflected on the half mirror and is converged by an image-forming action of the reflective image-forming element as a light spot on a scanned face to perform an optical scanning operation. The reflective image-forming element has a function for substantially performing the optical scanning operation using the light spot at an equal speed. The reflective image-forming element is arranged such that the reflective image-forming element is shifted by a predetermined shifting amount in a direction perpendicular to the beam deflecting face to correct the curve of a scanning line on the scanned face. Other optical scanners are also shown.

摘要： In an image forming reflecting mirror for a constant speed optical scan, a light beam is convergent in a cross scan-corresponding direction with a point near a starting point of deflection as a starting point of the light beam, and the light beam is deflected at an equal angular velocity and is converged to form a light spot on a scanned face so as to optically scan the scanned face at a constant speed. The image forming reflecting mirror has a shape on a deflecting-reflecting face represented by the following general formula, Y.sup.2 =2RmX-(K+1)X.sup.2, where X designates a coordinate in the direction of an optical axis and Y designates a coordinate in a direction perpendicular to the optical axis with a position on the optical axis as an origin, and Rm designates a radius of curvature on the optical axis and K designates a conical constant. The image forming reflecting mirror has a concave mirror face of a barrel or saddle type in the cross scan-corresponding direction which is separated by a distance Rs from a mirror face on the optical axis and is formed by rotating the shape with an axis perpendicular to the optical axis on the deflecting-reflecting face as a rotational axis. A new conical constant E=K+1 satisfies the following condition, -2.ltoreq.E.ltoreq.15.

摘要： In an optical scanner, a light source emits a light beam and a coupling lens changes this light beam to a convergent, divergent or parallel light beam. An optical deflector deflects the light beam from the coupling lens at an equal angular velocity. The deflected light beam is converged onto a scanned face by an image forming mirror and an elongated cylindrical optical element to perform an optical scanning operation at an equal speed. An optical path separating device separates an optical path of light reflected on the image forming mirror from an optical path of incident light from the light source to the image forming mirror. A reflecting face of the image forming mirror is constructed by a coaxial aspherical surface. The elongated cylindrical optical element has positive refracting power only in a direction perpendicular to a longitudinal direction thereof and is arranged between the image forming mirror and the scanned face in a state in which this longitudinal direction is parallel to a main scan-corresponding direction. In this optical scanner, a change in diameter of a light spot caused by field curvature is effectively reduced.
