Abstract: An inspection device for inspecting an inspection object of a PTP sheet including a pocket portion formed in a container film, and a cover film mounted to the container film to close the pocket portion, or a portion of a PTP film forming the PTP sheet, includes: an irradiator that irradiates the inspection object with a predetermined light; an imaging device that takes an inspection image of the irradiated inspection object and a peripheral portion of the inspection object; and a processor that: determines whether the inspection object is defective or non-defective based on inspection image data of the inspection object taken from the inspection image. The inspection image data includes data of respective pixels corresponding to an inspection target area subjected to the defective/non-defective determination, and data of respective pixels corresponding to a non-inspection target area that excludes the inspection target area.

Abstract: A vacuum pressure control apparatus includes an annular elastic seal member formed with a valve seat, and a doubly eccentric butterfly valve element configured to come into contact or separate from the valve seat. The vacuum pressure control apparatus is to be placed on a pipe connecting a vacuum chamber and a vacuum pump. The vacuum pressure control apparatus is configured to rotate the butterfly valve element in a first direction from a first valve closed position corresponding to an initial state to change vacuum pressure in the vacuum chamber. The vacuum pressure control apparatus further includes a control unit configured to rotate the butterfly valve element in a direction opposite to a first direction so that the butterfly valve element is moved to a second valve closed position different from the first valve closed position.
