A medicine dispensing apparatus in which a medicine guide assembly is constituted from first and second split guide members and in which substantially no dust is generated through rubbing between the first and second split guide members. The gap between a pair of guide paths of a pair of linear guide mechanisms provided for a pair of medicine feeder storing units, that is, paths along which movable slide portions slide on fixed guide portions, becomes wider in a drawing direction in which the medicine feeder storing units are drawn out.
