Claim 16:
17. A method of inspecting a package comprising a first film made of an opaque material and a second film made of an opaque material attached to each other and a plurality of spaces each for placing a tablet between the first film and the second film, the method comprising:
irradiating, with a predetermined electromagnetic wave by an electromagnetic wave irradiator from a first film side, the package that is conveyed along a predetermined direction and that has the spaces at a plurality of positions in a width direction perpendicular to the predetermined direction;
every time the package is conveyed by a predetermined amount, sequentially outputting an electromagnetic wave transmission image obtained by detecting electromagnetic wave transmitted through the package by using an imaging device disposed opposed to the electromagnetic wave irradiator across the package;
converting a coordinate system of the electromagnetic wave transmission image into a coordinate system of the package based on a positional relationship among the electromagnetic wave irradiator, the package, and the imaging device; and
inspecting the package based on the electromagnetic wave transmission image converted into the coordinate system of the package.
