Description
たとえば、前述の実施形態では、錠剤測定装置10の処理対象を円形の錠剤としたが、本発明による測定装置は、円形錠剤以外にも、オブロング錠やキャブレット錠、多角形錠剤など種々の形状の錠剤に対応可能である。また、前述の実施の形態では錠剤供給部40に無振動タイプの回転フィーダ41を配しているが、振動タイプのフィーダを使用することも可能である。さらに、高さ調整機構32も、モータとボールねじによる構成以外も採用可能であり、たとえば、駆動源として空圧や油圧のアクチュエータや、動力伝達機構としてラックアンドピニオンなどを使用しても良い。なお、モータも回転駆動するものには限定されず、リニアモータも適用可能である。また、前述の全数検査の実施においては、使用する光学センサをNIRに替えて、ラマン分光やTHzを用いることも可能である。
