A tablet dispensing apparatus that allows easy cleaning of the inner surfaces of temporary storage structures. A simultaneous driving mechanism and a plurality of open-close mechanisms of a plurality of temporary storage structure are coupled to each other by a plurality of coupling structures. The coupling structures are each configured to release the coupling when the entire temporary storage structure or a portion, which includes the open-close mechanism, of the temporary storage structure is drawn out of a housing, and to establish the coupling when the entire temporary storage structure or the portion, which includes the open-close mechanism, of the temporary storage structure is pushed into the housing.
