PROBLEM TO BE SOLVED: To provide an inspecting device and method capable of clearly capturing chips in tablets, missing, powder catching failures, and failures in mesh- shaped protruded parts in PTP preparation. SOLUTION: The PTP preparation inspecting device includes a light source 2 arranged in front of a packaged article 1, a linearly polarizing filter 3 on the side of incident light arranged between the light source 2 and packaged article 1, so that the light from the light source 2 turns unto a linearly polarized light in a prescribed direction, a camera 5 to pick up the image of the packaged article 1, and a linearly polarizing filter 6 on the side of light reception, arranged between the packaged article 1 and camera 5, so as to interrupt the linearly polarized light which is reflected regularly at a sheet member 7 and film 8. |
