Abstract: An inspection device is used in manufacture of a PTP sheet that comprises 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 emits near infrared light; a light shield that is placed between the illumination device and the container film and prevents the near infrared light from entering the container film; a through hole in the light shield that allows the near infrared light to pass through; a spectroscope that disperses reflected light from the content; an imaging device that images an optical spectrum of the reflected light and obtains spectroscopic image data; and a controller that: obtains spectral data of the content based on the spectroscopic image data; and performs a predetermined inspection with regard to the content based on the spectral data of the content.

Abstract: A three-dimensional measurement apparatus measures measurement targets placed in a target measurement area on a measurement object. The apparatus includes: a measurement module that: is positioned with respect to the target measurement area, and includes: a first irradiator that irradiates the target measurement area with predetermined light for height measurement; a second irradiator that irradiates the target measurement area with predetermined patterned light for three-dimensional measurement; and an imaging device that takes an image of the target measurement area; and a control device that moves the measurement module in a height direction and successively positions the measurement module at a predetermined height position determined by mapping, and performs, based on image data taken by irradiating the target measurement area with predetermined patterned light, three-dimensional measurement to the measurement targets at the predetermined height position.

Abstract: A three-dimensional measurement device performs three-dimensional measurement of a measured object using a phase shift method. The three-dimensional measurement device includes: an irradiator that irradiates the measured object with a predetermined light pattern having a light intensity distribution in a fringe shape; a control device that shifts a phase of the light pattern radiated from the irradiator in N different ways, where N is a natural number of not less than 3; and an imaging device that takes an image of the measured object irradiated with the light pattern. The control device executes three-dimensional measurement of the measured object by the phase shift method based on N different image data taken under the light pattern having the phase shifted in the N different ways.

Abstract: A blister sheet includes a container film comprising pockets receiving a content, and a cover film mounted to the container film to close the pockets. The container and the cover film are made of synthetic resins. The cover film is thinner than the container film. One pair of cuts formed for each pocket passes through the container and the cover film and extends to the pocket such that each pocket is placed between the cuts. The container and the cover film are broken from the one pair of cuts toward the pocket. A cutting slit or perforation is formed in the container film to allow for separation of the blister sheet into sheet pieces. The cutting slit or perforation is extended to intersect with the cut and a portion of the cutting slit or perforation that intersects with the cut passes through the container and the cover film.
