摘要： An optical transmission hinge apparatus includes a first hinge portion for pivotally interconnecting a first casing and a second casing about a first axis, a first optical device provided in the first casing, a second optical device provided in the second casing and an optical guide path member for interconnecting the first optical device and the second optical device to enable optical transmission therebetween. The optical guide path member includes a bent portion, a first portion formed on one side of the bent portion and a second portion formed on the other side of the bent portion. The first portion is provided in the first casing to be coaxial with the first hinge portion, with a terminal end of the first portion being in opposition to the first optical device. The second portion is provided in the second casing, with a terminal end of the second portion being in opposition to the second optical device.

摘要： In a triangular-sectioned prism 11 having a first plane 11a opposite an end face of an optical fiber 12, a second plane 11b opposite a light receiving element 13 and a third plane 11c which reflects received light 21 incident thereon from the optical fiber 12 toward the second plane 11b and transmits transmission light 22 emitted from a light emitting element toward the first plane 11a, a cylindrical member 32 of a refractive index larger than that of the prism 11 is embedded in that area of the prism 11 which is opposite the end face of the optical fiber 12. The cylindrical member 32 effectively suppresses the leakage therefrom of light, providing increased optical coupling efficiency as compared with that achievable by use of a mere prism structure.

摘要： Attachments are respectively attached to one ends of a pair of light guides, which are integrally formed via a connecting portion, such that the attachments surround the one ends of the light guides. The one ends protrude from a rear face of a receptacle body and are opposed to a light-emitting device and a light-receiving device, respectively. The attachments are inserted and positioned in guide holes formed respectively on the light-emitting device and the light-receiving device, and the optical axes of the pair of light guides and the optical axes of the light-emitting device and the light-receiving device are aligned with each other.

摘要： The object of the present invention is to suppress a decrease in the optical function of a sleeve by ensuring that a liquid chemical substance is not apt to remain on a peripheral surface of the sleeve even when the liquid chemical substance enters a connector. The present invention relates to an optical connector which is connected to an optical plug holding an optical fiber to a terminal end of which a ferrule is attached. The optical connector of the present invention has a guide pipe into which a ferrule is inserted and on an inner circumferential surface of which a supporting portion (a convexity) is formed, a light-emitting device, a light-receiving device, and a sleeve which is positioned by the supporting portion and optically connects the light-emitting device, the light-receiving device and the optical fiber. According to the present invention, there is a space between the guide pipe and the sleeve and, therefore, the phenomenon that a chemical substance adheres to a wide area and remains does not occur.
