Image Generating Apparatus

An image generating apparatus comprising:

• a light-emitting device portion emitting light for display;
• a light guide member, so arranged as to enclose said light-emitting device portion, including a peripheric emission surface, a peripheric light guide portion guiding said light emitted from said light-emitting device portion to said emission surface and a dome portion, having a light guide function, provided inside said peripheric light guide portion continuously with said light guide portion for covering said light-emitting device portion;
• a lid member so provided as to cover said dome portion of said light guide member;
• and
• an infrared receiving portion provided on a region covered with said dome portion to be adjacent to said light-emitting device portion, wherein
• said dome portion includes a first hole and a second hole,
• said lid member includes a wall portion inserted into said first hole of said dome portion for adjusting said light emitted from said light-emitting device portion and guided to said peripheric emission surface,
• said peripheric emission surface is circumferentially formed in plan view,
• said wall portion of said lid member is arcuately formed along said circumferential emission surface to protrude downward from said first hole of said dome portion,
• said first hole of said dome portion is in the form of an arcuate slot corresponding to said arcuate wall portion,
• said wall portion includes cylindrical positioning portions provided on both ends of said wall portion with an outer diameter substantially identical to the inner diameter of both ends of said first hole of said dome portion,
• said lid member functions as an infrared filter member, and
• said wall portion is integrally formed on said lid member.
