Claims (4)
- 指紋を検出する装置であって、指載せ台を形成する透明な最上層を有し、指載せ台から遠い方にある最上層の側に、評価回路に接続されるマトリクス配置の感光素子の層と、発光素子とが設けられているものにおいて、最上層(7)の指載せ台とは反対の側で、互いに交差する導体条片(5,6)からなる2つの電極薄膜(3,4)の間に、有機半導体に基く光活性薄膜(2)が設けられ、これらの導体条片のうち光活性薄膜(2)と最上層(7)との間の導体条片(5)が透明に構成され、光活性薄膜(2)が、両方の電極薄膜(3,4)の導体条片(5,6)の交差範囲に、発光素子(8)及び感光素子(9)を形成していることを特徴とする、装置。
- 発光素子(8)の範囲にある光活性薄膜(2)が、感光素子(9)の範囲に対して異なる構造を持っていることを特徴とする、請求項1に記載の装置。
- 感光素子(9)の出力信号が、それぞれ起動される発光素子(8)の場所的状態に関係して、評価回路(10)へ読込み可能であることを特徴とする、請求項1又は2に記載の装置。
- 感光素子(9)の出力信号が、発光素子(8)の起動に時間的に関係して、評価回路(10)へ読込み可能であることを特徴とする、請求項1〜3の1つに記載の装置。
