Abstract: A dispenser for fungible articles such as pharmaceutical tablets in which an elongated trough is vibrated at a downwardly oriented horizontal angle to dispense articles is single file alignment. An optical detector is mounted adjacent to the trough discharge end and is coupled to a counter for indicating the number of articles dispensed from the trough. The counter may be preset by an operator to dispense a preselected number of articles. The trough is releasably held to the dispenser cabinet by electromagnets which are energized simultaneously with the vibration motor. A container into which articles are to be dispensed is releasably captured beneath the discharge end of the trough adjacent to the detector.
