A device for handling thin, waferlike elements and by which such elements can be transferred discretely from a supply stack to a rotatable carrier and from said carrier to a receiving stack. The transfer is accomplished by a mechanism that is operated in timed relation to the rotation of the carrier and by means of a vacuum that is applied for a period of time sufficient to effect the transfer. The mechanism includes an arrangement of members whereby one of the members is maintained in a path of movement that is the same as that of said element when on said carrier. During such maintenance period, the element is deposited on the carrier or removed therefrom.
