  • Publication number: 20110228512
    Abstract: A measuring instrument includes a light source, a dial plate which has a scale design, and a light guide member which is provided between the light source and the dial plate, and guides a light received from the light source to the dial plate. The light guide member has a first face that faces to the dial plate and a second face that is opposite to the first face. The light guide member includes a light receiving portion for receiving the light from the light source, and a flat plate portion for irradiating the light transmitted from the light receiving portion to the dial plate. The scale design is arranged in a circular shape around the light source in view from an opposite side of the light source with respect to the dial plate.

  • Patent number: 7988310
    Abstract: A sheet-shaped lightguide member has a first surface (11A), which is divided into at least two areas. The sheet-shaped lightguide member has the first surface (11A) and a second surface (11B) that face each other and a peripheral edge surface (11C). The lightguide member receives light through at least a part of the peripheral edge surface, guides the light, and emits the guided light from the first surface (11A) serving as a light exit surface. The lightguide member is divided into the at least two light exit areas (14A, 14B) and has a light-blocking part (18) provided along a boundary between mutually adjacent light exit areas to block transmission of light between the adjacent light exit areas.

  • Patent number: 7960013
    Abstract: An illuminated indicator and a method of manufacturing the illuminated indicator that can make black the color of an indicator mark formed by irradiation with laser light are provided. In a shift position indicator panel, part of a light-blocking coating material layer and a design coating material layer is removed by irradiation with laser light, and part of an indicator coating material layer, which is created as a result of coating materials of three primary colors being mixed together, is exposed, whereby an indicator mark is formed. As long as the mixed coating material configuring the indicator coating material layer is made black by toning resulting from mixing coating materials of three primary colors, the color of the indicator mark also becomes black.

  • Patent number: 7959311
    Abstract: A portable electronic device having an illuminated keyboard includes a display having a recessed portion and a main body pivotally connected with the display. The main body includes a casing, a keyboard, a fastening element, and a plurality of light-emitting elements. The keyboard is disposed at the casing and includes a plurality of keys made of a first light-transmitting material. Each key has a light incident surface and a light output surface. The fastening element is fastened to the casing and has a first portion made of a second light-transmitting material. The fastening element corresponds to the recessed portion. The light-emitting elements are disposed in the fastening element. The light emitted by the light-emitting elements passes through the first portion of the fastening element to directly enter into the key through the light incident surface and to be outputted from the key through the light output surface.

  • Patent number: 7954965
    Abstract: A display for measured quantities can include a gauge with a set of indicia spaced around the gauge to indicate the measured quantities. A window can be formed in the gauge that extends along the set of indicia. An elliptical reflector can be positioned such that a first focus of the elliptical reflector is on the same axis as the center of the gauge with this axis perpendicular to the axis connecting the foci. An optical device can be mounted on a shaft and be arranged to redirect a light beam from a second foci of the elliptical reflector onto the elliptical reflector to generate a virtual pointer in the window. Means can be provided for turning the shaft to rotate the optical device. A light source can project the light beam onto the optical device. Rotation of the optical device can enable the virtual pointer to be selectively aimed at the set of indicia.
