[0032] The products are stacked and placed in material boxes 7. The material boxes 7 filled with products are conveyed to the waiting material conveyor line 2 via the loading conveyor line 1. Then, the waiting material conveyor line 2 conveys the material boxes 7 filled with products to the photography station, where the photography mechanism 4 takes pictures of the products. After the photography is completed, the transfer mechanism 6 transfers the products to the empty material boxes 7 placed at the waiting material station.
