- 紙葉類に光を照射する照明装置と、前記照明装置から出射された紙葉類を透過した光を導くためのレンズアレイと、前記レンズアレイにより導かれた透過光を受光する受光素子とを備えた紙葉類の認識装置において、
前記照明装置は、長手状に延びる導光体と、前記導光体の長手方向の少なくとも一方の端面付近に配置された光源と、前記光源から前記導光体に入射した光を紙葉類に向けて出射するための光拡散パターンとを有し、
前記光拡散パターンは、前記導光体に形成された複数の楔状の溝により構成され、
前記複数の楔状の溝の各々は前記長手方向の直交方向に同じ長さを有し、前記長手方向に等しいピッチを開けて配列されており、
各楔状の溝は、前記長手方向の断面形状が二等辺三角形状をし、かつ楔状の溝の開口幅(前記二等辺三角形の底辺の長さ)は等しいが、前記光源からの距離に比例して、前記楔状の溝の深さ(前記二等辺三角形の高さ)が次第に浅くされていることを特徴とする、紙葉類の認識装置。 - 前記光拡散パターンの前記長手方向の寸法は、前記受光素子の読取領域の幅よりも大きいことを特徴とする、請求項1に記載の紙葉類の認識装置。
