Patent number: 7171088Abstract: A number of optical fiber cords 11 are bundled together to constitute an image fiber. A first end of the image fiber 12a is incorporated within and covered by a cylindrical member to constitute an imaging section, which in turn forms one of a plurality of imaging sections. The second end of the image fiber is incorporated within a fiber bundling unit so that an image pickup device simultaneously read images captured by the plurality of imaging sections and transmitted to the image pickup device via optical means. Within the fiber bundling unit a plurality of cylindrical holes are provided, in an orderly fashion and in a lattice pattern, and into at least one cylindrical hole one end of the image fiber that forms an imaging section is inserted. All of the end faces of a plurality of image fibers are aligned in the same plane to thereby form a flattened surface.Type: GrantFiled: February 20, 2002Date of Patent: January 30, 2007Assignee: Sony CorporationInventors: Yoshimi Koyama, Tsukasa Yoshimura

Publication number: 20030103744Abstract: A number of optical fiber cords 11 are bundled together to constitute an image fiber 12a. One end of the image fiber 12a is incorporated within and covered by a cylindrical member 14 to constitute an imaging section 15a, which in turn constitutes one of a plurality of imaging sections. The other end of the image fiber 12a is incorporated within a fiber bundling unit 16 so that an image pickup device is able to simultaneously read images captured by the plurality of imaging sections and transmitted via optical means. In the fiber bundling unit 16 are provided a plurality of cylindrical holes 17 including a cylindrical hole 17a in an orderly fashion and in a lattice pattern, and into the cylindrical hole 17a is inserted one end of the image fiber 12a that constitutes the imaging section 15a. At the same time, all of the end faces of a plurality of image fibers including the image fiber 12a are aligned in the same plane to thereby form a flattened surface.Type: ApplicationFiled: October 28, 2002Publication date: June 5, 2003Inventors: Yoshimi Koyama, Tsukasa Yoshimura
