Abstract: After presentation target information for presenting information of a predetermined content to a user has been newly received from a predetermined server, a first notification that urges the user to check the newly-arrived presentation target information is displayed. Thereafter, while the presentation target information has not yet been checked, a second notification that urges the user to check the unchecked presentation target information is displayed periodically or according to a predetermined time schedule. The presentation target information is displayed when an operation to check the presentation target information is performed to the first notification or the second notification has been performed.

Abstract: An optical connector-equipped fiber (2A, 2B) has optical fibers (10a), a ferrule (11), guide holes, and a structure for regulating a space between end faces (11a) of the ferrules (11). A relative position between the end faces (11a) is fixed by guide pins being inserted into the guide holes.

MFDs of the optical fibers are gradually expanded toward the leading end faces and are maximized at the leading end faces. The optical axes of the pair of facing optical fibers that are optically coupled are not present on the same optical axis.
