になる。The lamp lead plate is composed of a bent portion to which the lamp 5 is welded, and a contact portion at the other end that contacts the pattern, and the contact portion is exposed from the bottom surface of the panel holder, so that it does not interfere with the panel holder. By placing it on a circuit board and fixing it with a screw or the like, electrical connection can be established with the pattern 2a with a spring property.
図に示されるとおり、ランプの近傍には反射板１０が設
置されている。As shown in the figure, a reflector 10 is installed near the lamp.
該反射板は透明プラスチックで作られており、下面は蒸
着により微細な凹凸のある梨地面に仕上げられている。The reflector is made of transparent plastic, and the bottom surface is finished with a pear-like surface with fine irregularities by vapor deposition.
このため、ランプ点燈時には、ランプからの光が該反射
板の内部で乱反射されながら、平面図の右端へ導かれる
と共に、上方へ照射される。Therefore, when the lamp is turned on, the light from the lamp is diffusely reflected inside the reflecting plate and is guided to the right end in the plan view and irradiated upward.
一方、反射板の上方には表示パネル１１が設けられてい
