[Problem that the idea aims to solve]

However, in such a case, as shown in FIG. The cylinder 48 installed along the bottle creates a blind spot 49 during the movement of the bottle 20, so The angle range that the person 46 can visually see is limited to approximately 50°. Therefore, the area that can be inspected is narrow. This causes the problem that accurate bottle inspection cannot be performed. Problems like this Therefore, if only one bottle conveyor is provided, many defective bottles will be missed. Ru. Therefore, in order to avoid this, conventionally two conveyors 41 and 42 were installed and two people were inspected. In addition to being uneconomical because bottle inspectors 46 and 47 have to be assigned, bottle inspectors 46 and 47 are When , 47 found a defective bottle, he stopped the movement of bottle 20 with one hand and removed the defective bottle with the other hand. The troublesome task of removing a good bottle must be done in an unstable sitting position. This may cause the bottle to fall without being able to stop its movement, or when being removed. Another problem is that by taking your eyes off the bottle, you may miss a defective bottle.

0004 Therefore, the purpose of this invention was to solve the problems of the conventional bottle inspection device as mentioned above. With a small space and fewer bottle inspectors, defective bottles can be easily and reliably detected. To provide a bottle inspection device that
