The rotary device includes a center pillar mounted in a pedestal, and rotatable circular plates or shelves mounted to individually freely rotate about the pillar. Vertical partitions are mounted on at least some of the shelves. These partitions extend from the central area of a shelf towards but short of the periphery thereof at which point a perpendicular wing is provided to constitute a guard. The ratio between the length of the partition and that of the wing is adjusted so as to maximize the area of the circular shelf which is used for storing articles and for filing documents, thereby leaving a negligible unused area of the shelf.
