PURPOSE: To improve the handling capability at the time when ampoules are taken out by a method wherein a case is carried by a case carrying means to a container take-out position, and after a door of the case is opened, a container push-out means is entered in the case from a long hole on the case, and containers in the case are taken out from the door.

CONSTITUTION: When a case 1 moves and reaches an ampoule take-out position 61, and registering is completed by pressing the side wall of the case 1 to a guide plate 23, a door opening signal is issued from a control unit 60 to a door opening/closing member, and a door 1b of the case 1 is opened. Then, a rod advancing command signal is issued from the control unit 60 to a support plate driving cylinder 34, and a support plate 33 advances until it comes into contact with the front row of ampoules 5.... Then, a rod retracting command signal is issued from the control unit 60 to the support plate driving cylinder 34, and at the same time, a rod advancing command signal is issued to a push-out plate driving cylinder 32. By doing this, while the support plate 33 is retracting, a push-out plate 30 enters a long hole 1c on the case 1, and therefore, the ampoules 5... are discharged outside of the case 1 from the opened door by the push-out plate 30 while being supported by the support plate 33.
