DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a Haramukodai automatic 'J barbetsu'. ), etc., to remove JJI by sorting out defective convexes that are located in defective areas.

〈Prior art〉 In the case of DT So/+1 f"T4);-, the collected raw seaweed is rolled out thinly"i)'i I is dried and made into a plate-shaped seaweed plate. -) A method is used in which a large number of sheets of raw seaweed of a predetermined shape are cut out from the seaweed plate.

However, in this case, since the raw seaweed is stretched thinly when forming the seaweed board, holes may be formed in the seaweed board, or the seaweed board may have holes. 34 is thin and has high plasticity, so it is easy to get scratches during cutting and other handling, and these holes and scratches formed in the raw nori will cause holes, cracks, and peripheral chips in the raw nori after production. It remains as a defective part of the missing number J@.

For this reason, defective moss on the defective part as described above seriously impairs the commercial value, so sub-1'.

It was stipulated that inspectors would inspect all raw seaweed after production, select C-defective seaweed, and then manually remove V1.

However, in the conventional inspection mentioned above, the inspector's flesh is 111V! ni J
5. Because of this, defective seaweed may be overlooked.
The reliability of sorting was poor, and as a result, there was a problem that defective seaweed that had not been sorted or removed from publication was supplied to consumers. Especially this thing [Jl, production (Iu ><t
