  • Patent number: 6155455
    Abstract: There is disclosed a vending machine in which a plurality of article columns are slant to be directed to a plurality of vending mechanisms, respectively. Each of the article columns is composed of a plurality of shelves for accommodating a row of articles. Each of the article columns is provided with a vending mechanism, so that articles of different kinds can be sold dependent on the number of the article columns. For this structure, at least one vending mechanism is set for an arbitrary one of article selection buttons. Thus, when the number of the article columns for accommodating the same kind of articles is set in accordance with the sales amount of the articles, different kinds of articles are sold out at an approximately same time.
