Keyboard device for displaying character by luminescent array and key unit thereof



<P>PROBLEM TO BE SOLVED: To provide a keyboard device for displaying characters by a luminescent array, and to provide a key unit of the keyboard device. <P>SOLUTION: A light-emitting device array is provided in each key unit in the keyboard device. A light-emitting device in the light-emitting device array is controlled by a keyboard control circuit in the keyboard device, and is selectively driven for generating rays. The generated rays are projected toward a key top for displaying characters on the key top. A key switch is arranged at the lower position on the key top and is driven for operation when the key top is pressed and operated, and a key signal is generated and is sent to the keyboard control circuit. <P>COPYRIGHT: (C)2006,JPO&NCIPI
【課題】 発光アレイで文字を表示するキーボード装置及びそのキーユニットの提供。 【解決手段】 キーボード装置の各キーユニット中に発光装置アレイが設けられ、該発光装置アレイ中の発光装置がキーボード装置のキーボード制御回路の制御を受けて、選択的に駆動されて光線を発生し、その発生する光線がキートップに向けて投射され、キートップ上に文字を表示する。キースイッチがキートップ下方の位置に配置され、該キートップが押圧操作される時に該キースイッチが駆動されて動作し、キー信号を発生してキーボード制御回路に送る。 【選択図】 図2
