    • A light source receiver 31 is disposed adjacent to an incident end face 11 of a light guiding plate 1 using the light source holder 31 for receiving the LED unit 4 and a light source holder 3 formed in an L-shape in a cross section having a standing plate 34 at one end of the light source holder 31, the standing plate 34 is disposed outside of a reflective plate 2 laminated on the light guiding plate 1, and a bolt 81 via a long hole 35 of the standing plate 34 is screwed into an insert-nut 8 of the light guiding plate 1 via a clearance hole 21 of the reflective plate 2, thereby the standing plate 34 follows the heat expansion or contraction of the light guiding plate 1 except the reflective plate 2. A relative position between the incident end face 11 of the light guiding plate 1 and the light source receiver 31 of the light source holder 3 is always constant, and the LED unit 4 is prevented from being damaged.
    • 光源接收器31使用用于接收LED单元4的光源保持器31和形成为L形的光源保持器3而布置在导光板1的入射端面11附近,该光源保持器3具有 在光源保持器31的一端的立板34中,竖立板34设置在层叠在导光板1上的反射板2的外侧,并且经由长边板34的长孔35将螺栓81​​拧入 导光板1的插入螺母8经由反射板2的间隙孔21,从而台板34跟随导光板1除反射板2之外的热膨胀或收缩。相对位置 导光板1的入射端面11和光源保持器3的光源接收器31总是恒定的,并且防止LED单元4被损坏。
