For example, the identified radio frequency information is less than the radio frequency information of the stored target area, and whether the radio frequency information is missed can be confirmed in the process.

Taking the case where the refrigerating apparatus recognizes less radio frequency information than the stored radio frequency information of the target area as an example. This may be considered a suspected "out of stock" in the refrigerator. At this time, the refrigerator controls the target area of the article storage 02 to move once again in the optimal recognition area, and then performs radio frequency recognition of each angle in the optimal recognition area once again on the target area. If the missing radio frequency information is identified, the 'ex-warehouse' condition is eliminated, and if the missing radio frequency information is still not identified, the refrigerating device determines that the vehicle is out of warehouse.

The object area of the article storage 02 is moved from the leftmost position to the rightmost position in the optimal recognition area. Or the target area of the article storage 02 moves from the rightmost side of the best recognition area to the leftmost side of the best recognition area.
