Abstract
An inspection device used in manufacture of a Press Through Package (PTP) sheet includes a container film including a pocket portion in which a content is placed and a cover film closing the pocket portion. The inspection device includes: an illumination device that irradiates the content with near-infrared light; a spectroscope that disperses reflected light from the content irradiated with the near-infrared light; an imaging device that takes an image of an optical spectrum of the reflected light dispersed by the spectroscope and acquires spectroscopic image data; and a controller that obtains spectral data of the content based on the spectroscopic image data, executes an inspection of the content based on the spectral data of the content, and executes good or poor quality judgment of the content.
