  • Patent number: 9122032
    Abstract: A light receiving device has a light receiving section for receiving a remote control signal light beam, and a light guide section for guiding the light beam to the light receiving section. The light guide section has a first reflection surface for reflecting the light beam to the light receiving section, the first reflection surface being disposed to oppose obliquely at a sharp angle to an entrance plane, and a second reflection surface for guiding the remote control signal light beam, the second reflection surface being disposed between the entrance plane and the first reflection surface. The first reflection surface includes a circular arc curved surface curved outward in a part closer to the entrance plane and farther from the light receiving section, and a linear inclined surface in a part approaching the light receiving section from the curved surface.

  • Publication number: 20140226267
    Abstract: A display device of the present disclosure includes: a display portion including a display face; a frame-shaped casing disposed so as to surround the display portion; and a decorative member disposed in contact with the casing. The decorative member is a light-transmissive member, and includes: a decorative portion forming a front face; and an attachment portion fixed to the casing and forming a back face opposite to the front face. The decorative member has formed therein a reflecting face configured to reflect light that is incident through the front face and travels in an inside of the decorative member along an optical axis direction perpendicular to the display face, and thereby to produce reflected light that travels in a direction different from the optical axis direction.
