Patent Number Title Of Patent Date Issued
4066351 Variable illumination optical system January 3, 1978
An optical system in which a screen modulates the light produced thereby. The intensity of the light image is varied as a function of screen position.
4005940 Optical system alignment apparatus February 1, 1977
An apparatus in which the alignment of an optical system is displayed, thereby enabling misalignments therein to be corrected. The alignment apparatus, in conjunction with the optical system, generates a narrow sample light image. This sample light image is displayed so as to depict
3998539 Illumination system December 21, 1976
An electrophotographic copying machine having a moving photoconductive member, in which an original document is illuminated by a pair of light sources, which are energized alternately to illuminate the document at a frequency of 240 hertz. This frequency of illumination prevents visible
3992108 Optical system alignment apparatus November 16, 1976
An apparatus in which the alignment of an optical system is displayed, thereby enabling misalignments therein to be corrected. The alignment apparatus, in conjunction with the optical system, generates a narrow sample light image. This sample light image is displayed so as to depict
3936173 Optical system February 3, 1976
An optical system in which a screened light pattern and a light image of an original document are projected onto a common region of a light receiving member forming a modulated light image thereon. Collimated light rays are employed in the formation of the screened light pattern.
