Patent number: 9477058Abstract: Technical Problem In the case where an optical fiber is wound around several times and housed, it is difficult to take out a terminal end of the optical fiber at a side wound around before. Solution to Problem A housing case includes: a body; and bobbin around which an optical fiber is to be wound, the bobbin being housed rotatably in the body, bobbin having a partition portion, partition portion having a fiber groove that guides the optical fiber between an inside and an outside of the partition portion, and the optical fiber being housed by housing a one end side of the optical fiber in the inside of the partition portion and by winding around an outer wall surface of the partition portion the optical fiber that has been guided to the outside of the partition portion with the fiber groove.Type: GrantFiled: October 30, 2014Date of Patent: October 25, 2016Assignee: FUJIKURA, LTD.Inventors: Yuu Takahashi, Susumu Okabe, Sawako Yamai

Patent number: 9453978Abstract: An optical module includes: a transparent substrate through which light can pass; a photoelectric conversion element mounted on the transparent substrate and emitting light toward the transparent substrate or receiving light having passed through the transparent substrate; and a support member supporting an optical fiber for transmitting light, the support member and the transparent substrate forming an optical path between the photoelectric conversion element and the optical fiber. A positioning hole is formed in the transparent substrate. A positioning pin having a tapered surface is formed on the support member. The transparent substrate and the support member are positioned with respect to one another by inserting the positioning pin into the positioning hole along the optical axis direction of light between the transparent substrate and the support member and by making the tapered surface of the positioning pin contact the edge of the positioning hole without leaving any space therebetween.Type: GrantFiled: June 2, 2014Date of Patent: September 27, 2016Assignee: FUJIKURA LTD.Inventors: Takayuki Tanaka, Sawako Yamai, Osamu Kikuchi, Susumu Okabe
