摘要：PROBLEM TO BE SOLVED: To provide an inspection apparatus for a can with a dent or buckling, which can detect a dent or buckling caused in a can circumference direction with high accuracy by a simple configuration requiring no rotating mechanism for a can.SOLUTION: The inspection apparatus for a can with a dent or buckling includes: annular illumination means for irradiating a body part of a metal can as an inspection object with light; and a plurality of cameras arranged to share a work of imaging the whole circumferential face of the can, each at an installation angle where the camera does not capture regular reflection light of illumination light when the can is in a normal shape but captures abnormal reflection light caused by a dent or buckling deformation generating in the can. The inspection apparatus is configured to inspect a can by determining whether or not the plurality of cameras captures abnormal reflection light from an inspection region of the can body part. 【課題】本発明が解決する課題は、缶回転機構が不要な簡単な構成で缶周方法に生じる凹み・座屈を高精度で検出できる凹み缶・座屈缶検査装置を提供することにある。【解決手段】本発明の凹み缶・座屈缶検査装置は、被検体である金属缶の胴部に光を照射するためのリング状照明手段を配備し、複数のカメラを缶が正常形状の場合には照射光の正反射光を捉えず、缶に生じた凹み・座屈変形に起因する異常反射光を捉える設置角度で、缶の全周面を分担して撮影するように配置し、複数のカメラが缶胴部の検査領域からの異常反射光をとらえたか否かにより検査できるようにした。【選択図】図１
