れている。2. Description of the Related Art Conventionally, for example, medical vials and rubber stoppers for the bottles have been required to be inspected for their appearance because they are used for medical purposes. However, since the shape is not only cylindrical, but also has a very complicated shape, it is often carried out visually. In particular, because of the cylindrical system, the inner surface inspection or groove inspection of the entire circumference must be observed from multiple directions when manually performed, and the work load is high. An automatic inspection was also considered to reduce the load, but it was difficult to inspect the inner surface of the cylindrical shape, particularly when there is a small concave portion below the groove, while transporting the inner surface. JP 8
Japanese Patent Publication No. 152417 discloses an apparatus for inspecting the inner surface of a cylindrical container on a rotary inspection table using a relay lens.

In the apparatus disclosed in Japanese Patent No. 52417, it is necessary to temporarily stop the article to be inspected relative to the imaging mechanism even though it is on the rotary inspection table, so that the apparatus becomes larger and the processing capacity decreases. Further, as another device that does not use such a device, there is a device that temporarily stops an article to be inspected on a transport path, inserts the tip of an imaging camera into a groove, and rotates the imaging camera at that position to take an image. But,
Even in this case, the apparatus is not as large as the apparatus described in the above-mentioned publication, but the processing capacity is not improved. Although there is a method of taking an image with a plurality of imaging cameras without rotating the image, the processing of the video signal becomes complicated, and the price of the apparatus rises. Further, if a minute notch is inspected with a fiberscope, the number of pixels is limited and the resolution is low, so that the inspection accuracy is low and the desired inspection standard is not satisfied.
