In an article management apparatus in which the weight of a bottle, including content, placed on a weighing scale is measured and tag data of a radio tag, indicating content of the bottle, which is affixed on the bottle is read out in a non-contact manner by a radio tag reading section through an antenna when the bottle is placed on the weighing scale, a compound data for discriminating whether or not content in a bottle is compoundable with contents in other bottles is stored. It is determined, based on the compound data stored, whether content of a first bottle on which a first radio tag is affixed can be compounded with content of a second bottle on which a second radio tag is affixed when the radio tag reading section reads out tag data of first and second radio tags.
