い、組合せ精度が著しく低下する虞れがあつた。 However, the dispersion plate has a long shape, and if the objects to be weighed are brought into the center of the plate all at once, the amount of the objects to be weighed will be unevenly distributed, and it will take time for the objects to be weighed to be evenly distributed on the dispersion plate. It takes a long time, and the combination accuracy tends to deteriorate. In addition, there are few objects to be weighed on the frequently used weighing hopper side, and objects to be weighed tend to stagnate on the less frequently used weighing hopper side, so the amount of objects to be weighed carried by each supply trough varies greatly. As a result, there was a risk that the combination accuracy would drop significantly.
