光源３が点灯され、光源３からの光９は導光板７を通っ
て押圧されたキー８を照明する。When the key 8 is pressed, the diaphragm 2 is pressed and the pattern 5 on the resin plate 6 is actuated to perform an input operation. At the same time, the light source 3 is turned on, and the light 9 from the light source 3 passes through the light guide plate 7 and illuminates the pressed key 8.
発明が解決しようとする課題
しかしながら、上記従来のキーボードでは次の２つの問
題点を有している。Problems to be Solved by the Invention However, the conventional keyboard described above has the following two problems.
（１）できるだけ広い面を光らして釦に光をもっていく
ため、多くの光源を必要とし、そのため消費電流も多い
。(1) In order to illuminate as wide a surface as possible and bring light to the button, many light sources are required, which also consumes a large amount of current.
（２）光を拡散させて導くため導光板が必要であり、キ
ーボードが厚くなる。(2) A light guide plate is required to diffuse and guide the light, making the keyboard thicker.
本発明はこのような従来の閉頭を解決するものであり、
１つの光源でしかも薄く構成できるキ−ボードを提供す
ることを目的とするものである。The present invention solves the conventional head closure problem,
The object of the present invention is to provide a keyboard that uses one light source and can be constructed thinly.
課頭を解決するだめの手段
本発明は上記目的を達成するために、操作回路パターン
を形成した樹脂板に１つの光源と複数の光ファイバーを
設置して光源からの光を光ファイバーを介して各キーに
振シ分けるようにしたものである。In order to achieve the above object, the present invention installs one light source and a plurality of optical fibers on a resin plate on which an operating circuit pattern is formed, and transmits light from the light source to each key via the optical fibers. It was designed to be divided into
作 用
本発明は上記のような構成により次のような作用を有す

ーンを形成した樹脂板に光源および光ファイバーを埋め
込むことによりキーボードを薄型に形成することができ
る。Effects The present invention has the following effects due to the above configuration. In other words, since the optical fibers distribute light to each key, a single light source can be used, and by embedding the light source and optical fibers in the resin plate on which the operating circuit pattern is formed, the keyboard can be made thinner. .
実施例

１を通って文字が光る。Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. Components having the same functions as those shown in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted. Reference numeral 6 denotes an optical fiber, which is configured to branch toward each diaphragm 2. The optical fiber 6 and the light source 3 are buried in a groove formed in the resin plate 4, and when the light source 3 lights up, the light passes through the optical fiber 6, hits the diaphragm 2, is reflected, passes through the key board 1, and the letters glow. .
第２図は光の経路を示すものである。FIG. 2 shows the path of light.
上記実施例によれば、１つの光源３からの光を光ファイ
バーで導光して各キー８に対応したダイヤフラム２に導
くようにしているので、多数の光源が不要となり消費電
力を低減させることができる。また、各ダイヤフラム２
近傍に光を導光しているので、キーの照明が均一化され
る。さらに、光源３および光ファイバー６は樹脂板４に
形成された溝内に埋め込んで形成できるので、キーシト
１と樹脂板４間に特別の板を設ける必要がなく、キーボ
ード全体を薄型構造化することができる。According to the above embodiment, since the light from one light source 3 is guided by an optical fiber to the diaphragm 2 corresponding to each key 8, a large number of light sources are unnecessary and power consumption can be reduced. can. In addition, each diaphragm 2
Since light is guided nearby, the illumination of the keys is uniform. Furthermore, since the light source 3 and the optical fiber 6 can be embedded in the groove formed in the resin plate 4, there is no need to provide a special plate between the key seat 1 and the resin plate 4, and the entire keyboard can be made into a thin structure. can.
発明の効果
本発明は上記実施例より明らかなようにキーを照明する
ための光源を１つにでき、１つ１つのキーにまで光を近
づけるため照明が均一になり、しかも消費電力を下げる
ことができる。また、光源。Effects of the Invention As is clear from the above embodiments, the present invention can use a single light source for illuminating the keys, and brings the light close to each key, making the illumination uniform and reducing power consumption. I can do it. Also a light source.
光ファイバーをパターンを形成した樹脂板に形成してい
るので薄型構造とすることができる。更に光で送るため
、ノイズ源等にもならないという効果を有する。Since the optical fiber is formed on a patterned resin plate, it can be made into a thin structure. Furthermore, since it is sent using light, it has the advantage of not becoming a source of noise.
