A tablet inspection apparatus (11) includes: a transmitted illumination unit (14) configured to emit infrared light to a medicine packet made of two films which enclose one or more tablets from a side of one of the two films, one of the two films having a printed portion, and the one or more tablets having lower absorption rate of infrared light than the printed portion; a reflected illumination unit (13) configured to emit infrared light from a side of the other of the two films; a camera unit (15) configured to obtain a transmission image by imaging the medicine packet from the side of the other, in a state where the transmitted illumination unit (14) is emitting infrared light and the reflected illumination unit (13) is not emitting infrared light, and obtain a reflection image by imaging the medicine packet from the side of the other, in a state where the reflected illumination unit (13) is emitting infrared light and the transmitted illumination unit (14) is not emitting infrared light; and a calculation unit (16) configured to generate an inspection image from a difference image between the reflection image and the transmission image. |
