Abstract
A multiple-product merchandising machine having a cylindrical drum mounted within a cabinet. The drum is divided into a plurality of horizontal shelves each of which is divided by a plurality of vertical walls into separate compartments from which the product can be dispensed. These compartments can be brought into alignment with access doors associated with each level and the doors, which are normally maintained locked, can be opened upon the insertion of adequate currency in the machine to remove the product. The access door locking system prevents more than one door from being opened at one time. The drum is rotatable in either direction by a reversible motor. A viewing area is provided in the front of the machine which allows a prospective customer to see the product as it passes by. The drum is divided into sections with opaque walls which prevent viewing from the viewing area of more than half of the compartments on a shelf when the drum is in its rest position. The drum can be restricted in its rotation so that less than all of the compartments can be accessed by the access doors. The section which is accessable can be changed at different times of day, or if the previous section has had a lot of its items sold so that a new supply of items can be viewed and accessed.
