The tablet inspection apparatus of the present invention includes an illumination unit 30 that irradiates light to a medicine package 20 in which at least a translucent tablet 22 is enclosed, an imaging unit 11 that acquires a transmission image of the irradiated medicine package 20, and transmission. And an image processing unit 12 that detects a tablet having a lower brightness at the outer peripheral part than the center part as a translucent tablet 22 using an image. The illumination unit 30 includes a light emitting unit 31, and the light emitting unit 31 and the medicine package A light collecting portion 33 that collects light is provided between the body 20 and a uniform outline of the semitransparent tablet 22 regardless of the photographing position. It is possible to perform 22 inspections. [Selection] Figure 1本発明の錠剤検査装置は、少なくとも半透明錠剤２２が封入された薬包体２０に光を照射する照明部３０と、照射された薬包体２０の透過画像を取得する撮像部１１と、透過画像を用いて、中心部よりも外周部の明度が低い錠剤を半透明錠剤２２として検出する画像処理部１２とを備え、照明部３０は、発光部３１を有し、発光部３１と薬包体２０との間に、光を集光する集光部３３を設けたことを特徴とし、撮影位置に関係なく半透明錠剤２２の均等な輪郭を得ることで、透過度に関係なく半透明錠剤２２の検査を行なうことが可能である。【選択図】 図１
