[Problem] The purpose of the present invention is to provide a drug inspection device capable of inspecting, with adequate precision, a drug accommodated in a divided bag on which printing is applied, and to provide a drug divided packaging system provided with the drug inspection device. [Solution] In a drug inspection device (10), medicine information detection control for detecting information for a drug which is the subject of inspection can be performed by a control device (60). The medicine information detection control is performed by: a drug candidate region extraction step for extracting a region of dark color in an image illuminated from a back side as a drug candidate region (A) in which a drug is assumed to be present, a printing candidate region extraction step for extracting a region in which printing applied to a divided bag is included as a printing candidate region (B) on the basis of an image illuminated from a front side, a printing region specifying step for specifying a region corresponding to the printing included in the printing candidate region (B) as a printing region (C) on the basis of a luminance distribution in the image illuminated from the back side, and a drug region derivation step for deriving a drug region (X) by subtracting the printing region (C) from the drug candidate region (A).Le problème de la présente invention est de produire un dispositif d'inspection de médicament capable d'inspecter, avec une précision adéquate, un médicament logé dans un sac divisé sur lequel est appliqué une impression, et de produire un système de conditionnement divisé de médicament comportant le dispositif d'inspection de médicament. Dans la solution selon l'invention, dans un dispositif d'inspection de médicament (10), une commande de détection d'informations médicales permettant de détecter des informations pour un médicament qui est le sujet de l'inspection peut être réalisée par un dispositif de commande (60). La commande de détection d'informa
