Using a synthetic resin smoke material (opaque material) that attenuates the It is shaped. 3a is provided on the cap and touches the back of the front panel to prevent light leakage. 3b is the top of the cap part 3 and the top of the knob, 3c is the top of the knob 3b This is a character cutout section provided in the . 11 is an illuminated knob, which is connected to the cap part 3 and the first It consists of a light guiding part, and both are integrally formed by two-color molding using synthetic resin material. There is. 12 is the first light guide part of the illuminated knob 11, which has a light guide property and diffuses light. It is made by two-color molding together with the cap part 3 using a synthetic resin opalescent material with a function. It is shaped. 12a is the bottom of the knob which is the bottom of the light guide 12, and 12b is the top of the light guide 12. The display character section provided, 13 is the front panel of the electronic device, 13a is the hole for the knob, and 13b is the front panel. 14 is a printed circuit board, and 15 is a light emitting member mounted on the printed circuit board 14. The lamp 16 is mounted on the printed circuit board with a slight gap between the bottom part 12a of the knob and the lamp 16. 17 is a synthetic resin milk with light guiding and light diffusing properties. Illuminated knob made of white material by normal molding process, 17a is the cap part, 1 7b is a painted lettering to prevent light leakage, and 17c is a painted flap provided on the cap portion 17a. 17d is a first light guiding portion, and 17e is a display character.
【０００４】 上記の様に構成した従来の照光式ツマミは図３(A)(B)に示す第１の例では、ツ マミの底部12a の近傍に設けたランプ15からの光を、ツマミ上部12b に拡散しつ つ導光する様に、合成樹脂の乳白材を用いて、キャップ部３と共に照光式ツマミ 11を二色成形により形成している。0004 In the conventional illuminated knob configured as described above, the first example shown in Figures 3(A)(B) The light from the lamp 15 provided near the bottom part 12a of the knob is diffused to the upper part 12b of the knob. In order to guide the light, a synthetic resin opalescent material is used together with the cap part 3 to provide an illuminated knob. 11 is formed by two-color molding.
【０００５】 そして、この照光式ツマミ11を、前面パネル13のツマミ用孔13a に、裏面13b 側から挿通し、図示していないバネ部材によって前面パネル13側に付勢して、押 し戻し自在に支持している。[0005] Then, insert this illuminated knob 11 into the knob hole 13a of the front panel 13, and insert it into the rear panel 13b. Insert it from the side, bias it toward the front panel 13 side with a spring member (not shown), and press it. We support it freely.
【０００６】 これにより、ランプ15からの光は導光部12を経由してツマミ頂部3bの表示文字 部12b を照明している。[0006] As a result, the light from the lamp 15 passes through the light guide section 12 and displays the characters on the top of the knob 3b. The section 12b is illuminated.
【０００７】 図４に示す第２の例では、導光性と光の拡散作用を有した合成樹脂の乳白材を 用いて、二色成形ではない通常の成形加工によりキャップ部17a と第１の導光部 17d を有した照光式ツマミ17を形成し、次に導光部17d を除くキャップ部17a 全 体に文字抜き塗装17b を施している。[0007] In the second example shown in Figure 4, a synthetic resin opalescent material with light guiding and light diffusing properties is used. The cap portion 17a and the first light guide portion are formed using a normal molding process other than two-color molding. 17d is formed, and then the entire cap part 17a except the light guide part 17d is formed. The body is painted 17b with letters removed.
【０００８】 そして、上記第２の例と全く同様にして、表示文字17e を照明している。[0008] Then, the displayed characters 17e are illuminated in exactly the same manner as in the second example.
【０００９】[0009]
しかし、上記した従来の照光式ツマミは、昼間の視認性を重視して、導光部に 用いた乳白材の乳白度を上げる（濃くする）と拡散効率が高くなり、光むらは軽 低減されるが、夜間での照度が高くなり過ぎて眩しくなるという欠点があった。 However, the conventional illuminated knobs mentioned above focus on daytime visibility, and the light guide section is Increasing the opalescence of the used opalescent material (darkering it) increases the diffusion efficiency and reduces uneven light. However, there was a drawback that the illuminance at night became too high and became dazzling.
【００１０】 また、夜間での照光を淡いものにしようとして、乳白色度を下げ（薄くし）透 明に近付けると拡散効果が弱くなり、光むらが発生しやすくなるという欠点があ った。そしてデザインや構造上の制約からツマミとランプが接近することが多く 、この場合更に光むらが発生しやすかった。0010 In addition, in an attempt to dim the illumination at night, the degree of opalescence was lowered (thinner) and the transparency was reduced. The disadvantage is that the diffusion effect becomes weaker when the light is brought closer to light, making it more likely that uneven light will occur. It was. Due to design and structural constraints, knobs and lamps are often placed close together. In this case, uneven light was more likely to occur.
【００１１】 更に、光むらや照度の調節のため形状変更をしていたので、金型費がかかって いた。[0011] Furthermore, the shape had to be changed to adjust light unevenness and illuminance, which increased mold costs. there was.
【００１２】 更に文字抜き塗装をしたものは、塗装がはげることがあった。0012 Furthermore, the paint may peel off when the letters are painted.
【００１３】 この考案は上記した点に鑑みてなされたものであり、その目的とするところは 従来例の欠点を解消し、照度を減少させ且つ光むらの無い照光式ツマミを提供す るところにある。[0013] This idea was made in view of the above points, and its purpose is to To provide an illuminated knob that eliminates the drawbacks of the conventional example, reduces illuminance, and has no uneven light. It's located where you are.
【００１４】[0014]

A first light guide section that diffuses and guides light from a light emitting member provided nearby to the top of the knob. A light-emitting knob made of synthetic resin consisting of This is a second light guiding section that diffuses and guides light while attenuating it.
【００１５】[0015]
この考案によれば、第２の導光部に光を減衰させるスモーク材と、光を導光し 拡散する乳白材を混合した合成樹脂材を用いたので、拡散作用を損わず、光を減 衰させた照光式ツマミとなり、昼夜とも同等の視認性が確保できる。 According to this invention, the second light guide part includes a smoke material that attenuates the light, and a smoke material that attenuates the light. Using a synthetic resin material mixed with a diffusing opalescent material, it reduces light without impairing the diffusing effect. It is a dimmed illuminated knob, ensuring equal visibility both day and night.

Note that the same parts as in the conventional example are given the same reference numerals, and the explanation thereof will be omitted.
【００１７】 図において、１は照光式ツマミであり、キャップ部３と第２の導光部から成り 、合成樹脂材を用いて二色成形により、両者一体に形成されている。２は照光式 ツマミ１の第２の導光部であり、導光性と光の拡散作用を有した乳白材及び光を 減衰させるスモーク材を適正な比率で混合した合成樹脂材を用いて、キャップ部 ３と共に二色成形により形成されている。[0017] In the figure, 1 is an illuminated knob, which consists of a cap part 3 and a second light guide part. Both are integrally formed by two-color molding using synthetic resin material. 2 is illuminated This is the second light guiding part of knob 1, and is made of a milky white material that has light guiding properties and light diffusing properties. The cap part is made of a synthetic resin material mixed with damping smoke material in an appropriate ratio. 3 and is formed by two-color molding.
【００１８】 2aは第２の導光部２の底部であるツマミの底部、2bは導光部２の頂部に設けた 表示文字部である。[0018] 2a is the bottom of the knob which is the bottom of the second light guide 2, and 2b is the top of the light guide 2. This is the display character section.
【００１９】 上記の様に構成した本考案の照光式ツマミ１は、導光性と光の拡散作用を有し た乳白材及び光を減衰させるスモーク材を適正な比率で混合した合成樹脂材を用 い、第２の導光部２とキャップ部３とを二色成形して一体に形成している。[0019] The illuminated knob 1 of the present invention configured as described above has a light guiding property and a light diffusing effect. A synthetic resin material is used, which is a mixture of a milky white material and a smoked material that attenuates light in an appropriate ratio. The second light guide section 2 and the cap section 3 are integrally formed by two-color molding.
【００２０】 そして、図３(A) に示す前記従来例と全く同様に、この照光式ツマミ１を、前 面パネル13のツマミ用孔13a に組み込んでいる。[0020] Then, just like the conventional example shown in FIG. 3(A), this illuminated knob 1 is It is incorporated into the knob hole 13a of the face panel 13.
【００２１】 これにより、ランプ15から発射した光は、ツマミの底部2a及び側部から入射し 、導光部２内で拡散し減衰して、適正な照度で照明むらも無く表示文字部2bを照 明する。[0021] As a result, the light emitted from the lamp 15 enters from the bottom 2a and side of the knob. , diffuses and attenuates within the light guide section 2, and illuminates the display character section 2b with appropriate illuminance and without uneven illumination.
