< Topic >Offer the device which does not need the operation which carries the target region to the certification position to which the operator is locked does the private certification with vein patternSolutionsThe certification device specifies, absorbs light, scan expedient and the suffering certification person who modify the memory expedient and the traveling direction remembers the blood vessel pattern of the target region of the legitimate user beforehand of the light which comes out of the illuminant the scan territory where when doing, the target region of the suffering certification person has been put in place operation vis-a-vis the object device in order to scan this scan territory with light, the control means which control scan expedient and the light which is reflected with the target region forms the blood vessel pattern of the target region of the suffering certification person on the basis of the light absorbent section and the electric information which convert this to the electric information,It has with the certification expedient which certifies, by comparing with this blood vessel pattern and the blood vessel pattern which is remembered in memory expedient.< Selective figure >Figure 1【課題】操作者が固定された認証位置に目標部位を持っていく動作を必要としない、静脈パターンによる個人認証を行う装置を提供すること【解決手段】認証装置は、正当な使用者の目標部位の血管パターンを予め記憶しておく記憶手段と、光源から出た光の進行方向を変更する走査手段と被認証者が対象装置に対して操作を行った時に被認証者の目標部位が置かれている走査領域を特定し、この走査領域を光で走査するように走査手段を制御する制御手段と、目標部位で反射した光を受光し、これを電気信号に変換する受光部と、電気信号に基づいて被認証者の目標部位の血管パターンを生成し、この血管パターンと記憶手段に記憶された血管パターンとを比較することにより認証を行う認証手段とを備えている。【選択図】図1
