<p>[Problem] To provide a drug inspection device and a drug inspection method which are capable of distinguishing between tablets that have different pharmaceutical ingredient amounts and are indistinguishable by appearance. [Solution] The present invention is a drug inspection device for distinguishing between the types of tablets in a tablet packaging process in which a plurality of tablets are conveyed while forming multiple lines, in each of which the tablets are housed in respective pockets, and have different pharmaceutical ingredient amounts on a line-by-line basis or a pocket-by-pocket basis, the device being provided with: an irradiation means which irradiates the tablets with a light beam including near infrared radiation; a spectroscope on which reflected light from the tablets are incident; a near infrared radiation image capturing means which captures an image of spectrum dispersed by the spectroscope and generates captured image data; and a control means which processes the captured image data and performs a calculation for distinguishing between the types of the tablets. The near infrared radiation image capturing means captures, in one-time image capturing, images of respective spectra of a predetermined number of pixels allocated to a predetermined length in the direction in which the tablets are arranged in the line, and the control means performs control such that the near infrared radiation image capturing means performs at least one-time image capturing on the tablets contained in one line, calculates average spectral data per tablet by averaging the spectra of pixels on the surface of the tablet on a pocket-by-pocket basis, and distinguishes between the types of the tablets on the basis of the average spectral data.</p> |
