Classification: CPC A  G | IPC A  G

Claim 0:
1. An inspection device that inspects 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 inspection device comprising:
an electromagnetic wave irradiator that irradiates, with a predetermined electromagnetic wave 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;
an imaging device that
is disposed opposed to the electromagnetic wave irradiator across the package,
comprises an electromagnetic wave detector comprising a plurality of detection elements that is arrayed along the width direction and that detects the electromagnetic wave radiated from the electromagnetic wave irradiator and transmitted through the package, and
sequentially outputs an obtained electromagnetic wave transmission image every time the package is conveyed by a predetermined amount; and

an image processing device that processes an image signal output from the imaging device, wherein
the image processing device comprises:
a processor that:
converts a coordinate system of the electromagnetic wave transmission image obtained by the imaging device into a coordinate system of the package based on a positional relationship among the electromagnetic wave irradiator, the package, and the imaging device, and
inspects the package based on the electromagnetic wave transmission image converted into the coordinate system of the package.
