A cassette (22, 34) for dispensing pharmaceuticals, the cassette (22, 34) comprising: a base defining an outlet and including a drive member, the drive member configured to be rotated; and a plurality of plate assemblies supported by the base in a stacked configuration, each plate assembly including a plate body defining an opening aligned with the outlet, a disk defining a plurality of cubbies, the disk being rotatable relative to the plate body by rotating the drive member of the base to selectively align each cubby with the opening in the plate body, and an indexing member configured to rotate the disk; wherein the disk of each plate assembly defines a central aperture and includes a projection that extends into the central aperture, wherein the central aperture is configured to receive the indexing member of an adjacent plate assembly stacked on top of the plate assembly, wherein the drive member engages and rotates the indexing member of the bottommost plate assembly, wherein when a cubby of a plate assembly is aligned with the opening in the plate body of the plate assembly, a pharmaceutical located inside the cubby drops out of the cubby through the opening, through a cubby and an opening of a plate assembly located beneath the plate assembly, if present, and out of the cassette (22, 34) through the outlet, and wherein after the disk of each plate assembly has completed a full revolution, the projection of the disk engages the indexing member of the adjacent plate assembly stacked on top of the plate assembly to rotate the disk of the adjacent plate assembly as the disk of the plate assembly rotates, wherein this process continues for each of the plate assemblies in the cassette (22, 34) until the cassette (22, 34) is empty. a base defining an outlet and including a drive member, the drive member configured to be rotated; and a plurality of plate assemblies supported by the base in a stacked configuration, each plate assembly including a plate body defining an opening aligned with the outlet, a disk defining a plurality of cubbies, the disk being rotatable relative to the plate body by rotating the drive member of the base to selectively align each cubby with the opening in the plate body, and an indexing member configured to rotate the disk; wherein the disk of each plate assembly defines a central aperture and includes a projection that extends into the central aperture, wherein the central aperture is configured to receive the indexing member of an adjacent plate assembly stacked on top of the plate assembly, wherein the drive member engages and rotates the indexing member of the bottommost plate assembly, wherein when a cubby of a plate assembly is aligned with the opening in the plate body of the plate assembly, a pharmaceutical located inside the cubby drops out of the cubby through the opening, through a cubby and an opening of a plate assembly located beneath the plate assembly, if present, and out of the cassette (22, 34) through the outlet, and wherein after the disk of each plate assembly has completed a full revolution, the projection of the disk engages the indexing member of the adjacent plate assembly stacked on top of the plate assembly to rotate the disk of the adjacent plate assembly as the disk of the plate assembly rotates, wherein this process continues for each of the plate assemblies in the cassette (22, 34) until the cassette (22, 34) is empty.
