Abstract

　予め基準となるマスターデータを入力して検出データと比較演算する必要がなくて汎用性を有し、簡単にシート状媒体の疲労を検出できる媒体疲労検出装置及び媒体疲労検出方法を得る。 　超音波をバースト波として発振する超音波送信素子（１１）と超音波受信素子（１２）と、受信感度検知部（２２）とを備えた媒体疲労検出装置。素子（１１），（１２）は両者の間を通過する紙幣などのシート状媒体（５）を介して対向する位置に配置され、素子（１１）から送信される超音波がシート状媒体（５）の主面に対して所定の入射角度θで入射する。シート状媒体（５）を透過した超音波の受信感度の変動を測定することで媒体（５）の疲労を検出する。
