Abstract: A point-light-source type light emitting portion faces a light incident face located at a corner portion of a light guide plate. A light diffusion pattern for emitting the light in the light guide plate from a light emission face is on the lower surface of the light guide plate. A diffusion prism sheet is on the light emission face. A prism sheet including prisms each having a concentric shape with the light emitting portion at the center is on the lower surface of the diffusion prism sheet, and an uneven diffusion plate is on the upper surface of the diffusion prism sheet. Light emitted from the light emission face of the light guide plate along the light emission face is deflected in the direction perpendicular to the light guide plate by the prism sheet, and the angle of beam spread of the light is spread by the uneven diffusion plate.

Abstract: By use of a simple structure, also without enlarging thickness and size too much, provided is a light emitting module which can improve heat dissipation of a light emitting component. On a surface of a wiring substrate, a pair of lands face to each other, and two wiring line is connected to the land, respectively. A mounting side outside electrode of a light emitting component is connected to a lead frame to which a light emitting element is die-bonded, and a non-mounting side outside electrode is connected to a lead frame which is connected to the light emitting element through a bonding wire. And, the mounting side outside electrode is bonded to the land by solder, and the non-mounting side outside electrode is bonded to the land by solder and thereby, the light emitting component is mounted on the wiring substrate. A line width of the wiring line at a side to which the mounting side outside electrode of the light emitting component is soldered is made to be larger than a line width of the wiring line at a side to which the non-mounting side outside electrode is soldered.

Abstract: A connection terminal 39 includes a clip piece 73 and a fixed piece 71 facing each other in the vertical direction, the interval between a claw 74A and a claw 74B provided on the tips of the respective pieces is slightly smaller than the thickness of a flexible printed board 48. Therefore, when the flexible printed board 48 is inserted into a board insert port 68, the flexible printed board 48 is sandwiched and held by the claws 74A and 74B. The flexible printed board 48 is thus temporarily held in the state in which it is inserted in the connector. A projection 77 is projectedly provided on an end of an operation lever 46, and the flexible printed board 48 is provided with a cutout 79 into which the projection 77 is fitted. As a result, after the operation lever 46 is tilted horizontally to fit the projection 77 into the cutout 79, the flexible printed board 48 will not come out of the board insert port 68. Thus, the flexible printed board 48 can be reliably prevented from coming off by the anchoring mechanism in the locked state of the connector.

Abstract: A protecting sheet 112 having a transparent rubber-like resin 113 formed on a transparent board 114 is interposed between a light emitting plane 123 of a light guiding plate 111 and a surface, at which prisms 116 are formed, of a prism sheet 115 in such a manner that the transparent rubber-like resin 113 is brought into contact with vertexes of the prisms 116. The transparent rubber-like resin 113 holds the prism sheet without any deformation without any application of external force, thus preventing any occurrence of an optical close contact between the prism sheet 115 and the protecting sheet 112. In contrast, the transparent rubber-like resin 113 is deformed with the application of the external force, thus preventing any breakage of the prism 116.
