摘要： In an electrostatic copying machine, a light source radiates an elongated, narrow beam of light onto an original document which is moved perpendicular to the beam of light for scanning. A plurality of imaging optical fibers are arranged in a row extending coextensively parallel to the light beam, which focus images of adjacent portions of the document onto a photoconductive member which is moved in a manner conjugate to the original document for scanningly forming an image of the document on the photoconductive member. The imaging optical fibers themselves extend parallel or at an angle to the document. First and second reflectors which may be mirrors or prisms are disposed between the document and imaging optical fibers and between the imaging optical fibers and the photoconductive member respectively to deflect the optical paths of the images. The light source may comprise a lamp and illuminating optical fibers which transmit light from the lamp onto the reflector disposed between the document and imaging optical fibers from which the light is reflected onto the document, thereby protecting the imaging optical fibers from heat damage.

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： This invention relates to an f.theta. lens for scanning a laser beam whose deflection half-angle reaches 30.degree.. If a deflection angle increases, the curvature of field and f.theta. characteristic are rapidly deteriorated. According to the present invention, the f.theta. lens is composed of two lenses. A first lens near a beam deflection point is formed by a meniscus lens substantially in the form of a concentric spherical surface. A power of the lens and a length between a common center of two refractive surfaces and a beam deflection point are suitably selected to well-correct the curvature of field and f.theta. characteristic over a wide scanning angle.

摘要： A post-objective type optical deflector, in which luminous fluxes are condensed by a convergent lens and thereafter deflected by a polygonal mirror, among apparatuses for scanning a laser beam, involves a problem in the deterioration of the curvature of field and the f.theta. characteristic. The deterioration of the curvature of field and the f.theta. characteristic may be corrected by forming a reflecting surface of a polygonal mirror into a convex surface or a convex cylindrical surface and adequately selecting the relationship between the distance A from the rotational center to the center of the reflecting surface, the radius of curvature R of the reflecting surface, the distance Lo from the deflection point of the polygonal mirror to the scanning surface, and the scanning width Yo.

摘要： In an image forming apparatus, a device for removing an image forming substance from a paper or similar image holding medium senses the orientation of fibers constituting the paper. While a light beam is emitted obliquely toward the paper, the diffused distribution distribution of the resulting reflection is measured in order to determine the orientation of the fibers. A preselected relation is set up between the fibers and the direction of paper transport on the basis of the determined orientation. Further, a condition for applying an unstabilizing liquid to the paper and a condition for drying the paper are varied on the basis of the determined orientation.
