Abstract
A pill dispenser mechanism is provided in which a multilayered compartment is releasably attachable to a receptacle for pills in such a way that pills may be selectively advanced into one compartment, then by selective advancement of one of the compartment layers transfer the pill from the first compartment into a discharge compartment to permit sequential recovery of pills therefrom. In order to accommodate different sized pills, the compartments may be provided with different sized openings to conform to the substantial size and configuration of the pill. Electrical contact switches may be associated with the compartments to sense for the purpose of recording the movement of a pill between one or more, or a combination of both, compartments.
