PROBLEM TO BE SOLVED: To decrease the thickness of an apparatus for executing detection of the vein pattern and determination of the presence or absence of alcohol.SOLUTION: An imaging apparatus 12 includes: a light receiving part 30 which forms a plurality of light receiving elements 34 for generating detection signals in accordance with the amount of received light on a substrate 32 and a light collecting part 40 which forms a plurality of lenses 44 for collecting incident light from a finger 200 to respective light receiving elements 34 on a substrate 42. A plurality of organic EL elements D including a plurality of first organic EL elements D1 irradiating the finger 200 with inspecting light of a wavelength λ1 and a plurality of second organic EL elements D2 irradiating the finger 200 with inspecting light of a wavelength λ2 are arranged between the substrate 32 and the substrate 42. A vein detecting part 74 detects the vein pattern of the finger 200 by utilizing detection signals generated by respective light receiving elements 34 when respective first organic EL elements D1 emit the light, and a liquor-drinking determining part 76 determines the presence or absence of alcohol in blood of the finger 200 by utilizing the detection signals generated by respective light receiving elements 34 when respective second organic EL elements D2 emit the light.COPYRIGHT: (C)2013,JPO&INPIT【課題】静脈パターンの検出とアルコール成分の有無の判定とを実行する装置を薄型化する。【解決手段】撮像装置12は、受光量に応じた検出信号を生成する複数の受光素子34を基板32に形成した受光部30と、指200からの入射光を各受光素子34に対して集光する複数のレンズ44を基板42に形成した集光部40とを具備する。基板32と基板42との間には、波長λ1の検査光を指200に照射する複数の第1有機EL素子D1と、波長λ2の検査光を指200に照射する複数の第2有機EL素子D2とを含む複数の有機EL素子Dが配置される。静脈検出部74は、各第1有機EL素子D1の発光時に各受光素子34が生成する検出信号を利用して指200の静脈パターンを検出し、飲酒判定部76は、各第2有機EL素子D2の発光時に各受光素子34が生成する検出信号を利用して指200の血中のアルコール成分の有無を判定する。【選択図】図3
