PROBLEM TO BE SOLVED: To provide an inspection device for a packed merchandise in which eggs are packed with which inspection can be reliably performed without depending on human work.SOLUTION: The inspection device for a packed merchandise in which eggs are packed comprises: carrier devices 11, 12 carrying a packed merchandise 100 to be inspected, in a carrying direction side-part imaging devices 31, 32 photographing the inspection image of the packed merchandise 100 at photographing positions set on the carrier devices 11, 12 and lighting fixtures 21, 22 which irradiate the packed merchandise 100 with irradiation light functioning as back light for the side-part imaging devices 31, 32. A packaging pack 101 has pit parts 103 which are made of transparent material and in which eggs 102 are housed. The side-part imaging devices 31, 32 capture the background region of the packed merchandise 100 as a light region, capture the image region of the silhouette of an egg shell blocking the irradiation light as a dark region, capture the image region of the pit parts 103 letting the irradiation light through, as the same light region as that in the background region, and capture the image region of leakage leaking from the egg shell and retaining in the pit parts as a dark region, in the inspection image on which the pit parts 103 are shown up.COPYRIGHT: (C)2014,JPO&INPIT【課題】人的作業によらずして確実に検査できる卵を詰めたパック商品の検査装置を提供する。【解決手段】検査対象のパック商品100を搬送方向に沿って搬送する搬送装置11、12と、搬送装置11、12の上に設定した撮影位置でパック商品100の検査画像を撮影する側部用撮像装置31、32と、側部用撮像装置31、32にとって逆光となる照射光をパック商品100に照射する照明器具21、22を備え、包装用パック101は透明材からなって卵102を収納するピット部103を有し、側部用撮像装置31、32はピット部103を写す検査画像において、パック商品100の背景領域を明領域として捉え、照射光を遮光する卵殻のシルエットの画像領域を暗領域として捉え、照射光が透過するピット部103の画像領域を背景領域と同じ明領域として捉え、卵殻から漏出してピット部に滞留する漏出物の画像領域を暗領域として捉える。【選択図】図1
