【産業上の利用分野】本発明は、電子機器のスイッチ部
に使用する照光式接点シートに関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illuminated contact sheet used in a switch section of electronic equipment.
【０００２】[0002]
【従来の技術】従来の照光式接点シートは、ＬＥＤある
いはＥＬにより裏側から文字部を照光している。2. Description of the Related Art In a conventional illuminated contact sheet, a character portion is illuminated from the back side by an LED or an EL.
【０００３】[0003]
【発明が解決しようとする課題】従来の照光式接点シー
トは、この接点シートの裏側に発光装置を配置する必要
があり、製造工程が増すばかりでなく、そのための空間
が必要となるため、薄型化が図れない欠点を有する。In the conventional illuminated contact sheet, it is necessary to dispose the light emitting device on the back side of this contact sheet, which not only increases the number of manufacturing steps but also requires a space for the thin sheet. It has a drawback that it cannot be realized.
【０００４】[0004]
【課題を解決するための手段】そこで本発明にあって
は、ＥＬシートをそのまま接点シートとして組み込み、
この上面に文字部を印刷するようにした。これにより製
造が簡単となり、かつ薄型化が図れるようにしたもので
ある。Therefore, in the present invention, the EL sheet is directly incorporated as a contact sheet,
The character portion was printed on this upper surface. As a result, the manufacturing is simplified and the thickness can be reduced.

【実施例】図１に実施例を断面図で示す。EXAMPLE FIG. 1 is a sectional view showing an example.
【０００６】弾性を有するＥＬシート１上に、色インキ

コーアドバンス：ＲＵＸ）にて、スクリーン印刷により
文字抜き印刷し、その上に透明樹脂（スリーボンド：Ｔ
Ｂ３００３）にてキートップ部４を形成して照光式接点
シートを作製した。なお、色付きＥＬシートを使用する
ことで、色インキ２の塗布を省略できる。Colored ink 2 is applied to an elastic EL sheet 1, and polyester black ink 3 (Seiko Advance: RUX) is applied on the EL sheet 1 to perform character printing by screen printing, and a transparent resin ( ThreeBond: T
B3003) was used to form the key top portion 4 to produce an illuminated contact sheet. By using the colored EL sheet, the application of the color ink 2 can be omitted.
【０００７】[0007]
【発明の効果】本発明によれば、薄型の照光式接点シー
トを少ない製造工程で製作できるので、製造が簡単であ
り、コストも低減できる。また、ＥＬシートの色を文字
部の色として直接利用することで、色インキの塗装工程
も省略でき、より製造コストを低減できる。According to the present invention, since a thin illuminated contact sheet can be manufactured by a small number of manufacturing steps, the manufacturing is simple and the cost can be reduced. Further, by directly using the color of the EL sheet as the color of the character portion, the step of coating the color ink can be omitted, and the manufacturing cost can be further reduced.
