Abstract: An ampule feeder which can discharge ampules one by one with high efficiency without the possibility of clogging. It includes an ampule container having a bottom plate pivotable in one direction. Ampules stored randomly in the container are moved onto an inclined top surface of an ampule receiver and raised. When the ampule receiver rises to its highest level, the ampules slide on its surface and drop onto a conveyor belt of a dispenser provided outside of the side wall of the ampule container. Ampules are thus discharged by the dispenser.
