<p>Provided are a drug inspection device and a drug inspection method that are capable of distinguishing tablets that have different amounts of active pharmaceutical ingredients and are indistinguishable in appearance. The drug inspection device according to the present invention is for distinguishing types of tablets in a tablet packaging process for tablets containing different amounts of active pharmaceutical ingredients, every row or every pocket, in which a plurality of rows each having aligned therein a plurality of tablets housed in respective pockets are conveyed, and includes an irradiation unit configured to irradiate the tablets with a light beam that includes near-infrared light, a spectroscope on which reflected light from the tablets is incident, a near-infrared imaging unit configured to capture a spectrum obtained through dispersion of the reflected light by the spectroscope and to generate image data, and a control unit configured to process the image data and to perform an operation for distinguishing the types of tablets. The near-infrared imaging unit is configured to capture the spectrums of a predetermined number of pixels allocated to a predetermined length in a direction in which the tablets are aligned in the row, and the control unit is configured to perform control such that the near-infrared imaging unit performs image capture at least once on the tablets included in the one row, to compute average spectrum data per tablet by averaging the spectrums of the pixels on a tablet surface every pocket, and to distinguish the type of tablet based on the average spectrum data.</p> |
