Abstract: An inspection device includes: an irradiator that radiates, before content is placed into the pocket, ultraviolet light toward one face of the container film; imaging devices that take images of the container film from another face side of the container film; and a processor that determines, based on the images, whether the pocket includes a pinhole, at least two of the imaging devices being each disposed on respective sides of the container film in a width direction such that the pocket is placed between the two imaging devices, and while the container film is being conveyed along a conveyance path, the two imaging devices take images of the pocket at a timing when the pocket is located at an upstream-side position, a middle-side position, and a downstream-side position of the conveyance path.

Abstract: An inspection device inspects a formation state of a pocket portion formed in a container film of a blister pack and includes: an illumination device that irradiates a container film including the pocket portion with a predetermined electromagnetic wave; an imaging device that takes an image of at least the electromagnetic wave transmitted through a bottom portion of the pocket portion and obtains image data; a control device that extracts, based on the image data, shading pattern data corresponding to a shading pattern occurring in the bottom portion of the pocket portion by irradiation with the electromagnetic wave; a storage that stores a neural network and a model, the model being generated by learning of the neural network using, as learning data, only shading pattern data of a pocket portion without any formation defect among the extracted shading pattern data.
