Abstract: In order for an apparatus for the sorting of objects, especially those of flat shape, to permit a simple and horizontal distribution of the objects, an endlessly circulating primary roller conveyor (2) is divided into roller sections (3.1, . . . ) of rollers (7.1.1, . . . , 7.1.n, 7.n.1, . . . 7.n.n) arranged in groups with window sections (5.1, . . . ) as gaps between them. Underneath the upper conveyor plane (upper run 2.1) and the lower return plane (lower run 2.2), secondary conveyors (11.1, . . . , 12.1, . . . ) are disposed in the intermediate space (2.3) of the roller conveyor (2). Roll-off systems (6.1, . . . ) are associated with the secondary conveyors, which, when operated by a control system, contact the rollers (7.1.1, . . . , 7.1.n, . . . , 7.n.1, . . . 7.n.n) of a roller section (3.1, . . . ), so that the object (4.1, . . . ) lying thereon is rolled away against the direction of movement of the roller conveyor (2) and falls through the window section (5.1, . . .
