In view of this, conventionally, Korean Patent No. 10-1555807 (hereinafter referred to as "Prior Art Document") has proposed an electronic weight discriminator in which a sensor conveyor is omitted.

In the checkweigher disclosed in this prior art document, the sorted goods or fish supplied to the supply plate are manually pushed into the drop holes of the supply plate, and the fish discharged through the drop holes are fed to the bottom plate of the original plate.

Then, the scrapers are rotated in the clockwise direction on the bottom plate to move the fish on the bottom plate, and the moved fish is weighed down onto the measurement plate through the holes of the supply plate.

After being weighed in this way, the fish are removed from the instrument panel by the scrapers and fed to the conveying conveyor.

However, in the checkweigher disclosed in the prior art document, a fish falling on a circular bottom plate is weighted on a measuring plate by a scraper rotating in a clockwise direction. In this case, a centrifugal force acts on a fish which is rotated by the scraper Even if the fish is placed on the measuring plate, the position of the fish is not constant and is provided at a different position. Accordingly, even if the fish of the same weight is used, the weight is different depending on the position of the fish on the measuring plate There is a problem that it is difficult to measure and accurately measure the weight.

Further, the scrapers for rotating the fish on the bottom plate differ in the load (driving force) acting on the scrapers depending on the positions where the fish are contacted, thereby causing different centrifugal forces to act on the fish which are rotationally moved by the scrapers.

The above-described fish sorting apparatus and techniques therefor are described in detail in the following prior art documents, so that a detailed description thereof will be omitted.
