An illuminating unit includes: a plurality of light sources; a light-guide plate including an end surface disposed to face the plurality of light sources, a first surface that outputs light which is based on incident light from the end surface, and a second surface that faces the first surface and includes a plurality of convex parts; and an optical sheet adhered to side of the second surface of the light-guide plate, with the plurality of convex parts being interposed therebetween. The plurality of convex parts include a plurality of first convex parts disposed in a first region inside the second surface, and one or plurality of second convex parts disposed in at least a portion of a second region on a periphery of the first region inside the second surface.

Illuminating unit and display apparatus

A molded part for use in electronic devices using an infrared remote control where the molded part is molded using an infrared transmissive material and an infrared blocking coating is applied thereon. A predetermined pattern of slits or dots is formed on the infrared blocking coating for permitting the transmission and reception of infrared signals.

It is made possible to locate arbitrarily a light guiding device and a light emitting means. A notch (11) having a triangular cross-section is formed on a bottom (inner) side of a light guiding device (10) formed so as to have a rectangular cross-section. Furthermore, a light emitting source (12) is provided under the notch (11) of this light guiding device (10). The light emitting source (12) is mounted on a circuit board (13), and controlled according to the state of control or setting in, for example, the electronic appliance. When the light ray from the light emitting source (12) is irradiated toward the notch (11), the emitted light ray is reflected by a reflective face (14) formed by the notch (11) so as to be a plane and a front face (15) of the light guiding device (10) becomes luminous. In addition, the irradiated light ray is partially transmitted through the reflective face (14), and a top face (16) of the light guiding device (10) also becomes luminous. As a result, the two outer faces (15) and (16) become luminous.

Light guiding device

A rear project cabinet for arear projection television set in which the screen and the mirror can be easily set in their positions and an optical accuracy can be established. The screen fixing segment and the mirror fixing segment constituting the rear projector cabinet are formed by plastic material in such a manner that each of its depth size and the inclination angle of the mirror may become a set value, thereby a well-focused appropriate screen can be attained by a mere coupling and assembling of these segments, and even in the case that the screen size at the screen fixing segment is different, it can be accommodated by applying a proper insert die during molding of the mirror fixing segment.

Rear projector cabinet

A cabinet molded in resin has a grill portion molded in resin by using a predetermined metal mold and having a plurality of holes of small diameter defined in the vertical and horizontal directions. This cabinet is composed of a plurality of substantially straight-lined reinforcing ribs formed on the rear surface of the grill portion, wherein the reinforcing ribs are disposed with a predetermined angle with respect to the direction in which a resin supplied from a resin injection nozzle to the metal mold is flowed upon molding and the reinforcing ribs cross one another.
