LED elements () which are light emitting elements are mounted on a substrate (). LED light guide plates () which are light-emitting-element light guide components are arranged at positions corresponding to the LED elements () of the substrate (). Each LED light guide plate () has a substrate-side protrusion () which is a portion to-be-held. The substrate-side protrusion () has a sectional shape which becomes smaller toward the substrate (). The substrate-side protrusions () are fitted into the holding holes () of a keeper plate () which is a holding member. The shapes of the holding holes () are different in accordance with the arrangements of the LED light guide plates () in a light guide direction. Thus, in spite of the same shape of the LED light guide plates (), the mounting heights thereof can be made different depending upon places. It is accordingly possible to provide a light emitting apparatus which can decrease the sorts of components.

A rail groove is provided on an outer peripheral portion of a focus adjusting ring. A lens seat, supporting an image pickup lens, is attached to an escutcheon forming a main body. A plurality of engaging protrusions, provided on a front surface of the escutcheon around the lens seat, engage with the rail groove. Cam surfaces, formed on the focus adjusting ring, are brought into contact with protrusions of a bracket which mounts an imaging element. The rotational motion of the focus adjusting ring is converted into a linear or progressive motion of a bracket by the cam surfaces.

Focus adjustment mechanism for a video or image pickup apparatus

The present invention provides an iris imaging apparatus is configured of a platform; a wide angle camera for imaging an image of a person to be authenticated; wide angle camera lighting devices controlled to emit light when the wide angle camera shoots; a telephoto camera for imaging the enlarged image of the eye of the person to be authenticated; iris lighting devices controlled to emit light when the telephoto camera shoots; first motors for rotating the iris lighting devices and directing the luminous light in the direction of the person to be authenticated; a turning stage mounted with the wide angle camera, the wide angle camera lighting devices, the telephoto camera, the iris lighting devices and the first motors, the turning stage rotatablly mounted on the platform; and a second motor for turning the turning stage. All the components required for the turning operation are mounted on the turning stage.
