Abstract: A collimator lens 311 emits by converting a light signal from an optical fiber cable 20 to a collimated light, for example. The collimator lens 311 is retained in a plug housing 315 coupled to a reception side optical connector of the light signal. When the plug housing 315 is not coupled to the reception side optical connector, the pressing portion 313a sets the position of the collimator lens 311 at a position at which the emitted light signal has a predetermined divergence angle. When the optical connectors of the transmission side and the reception side are not connected, the light signal emitted from the optical connector of the transmission side is dispersed, and therefore emission of the light signal is prevented from giving a bad influence to a visual perception function or the like.

Abstract: A lens 311 of a plug 31 converts a light signal from an optical fiber cable 20 to light of a predetermined divergence angle in order to emit the light. A plug housing 315 fixes the optical fiber cable 20 and the lens 311.

The light signal emitted from the plug 31 becomes dispersed when entering into the eyeball of a nearby person, and therefore can be prevented from exerting adverse effect on visual function and the like.
