A liquid medicine dispensing device includes a rotary unit 12 which rotates while holding a plurality of original drug vials 100, and a conveyance mechanism that conveys a prescription bottle 110 in the horizontal direction on the underside of the rotary unit 12. Each of the original drug vials 100 is connected with a discharge nozzle 17 to which a discharge valve 26 is attached, and an air nozzle 29 connected with a pump and an atmospheric relief valve. When discharging liquid medicine, the prescription bottle 110 is conveyed in advance to a position that is directly below an original drug vial 100 required for dispensing. In that state, the original drug vial 100 is inverted by rotating the rotary unit 12 by 180 degrees, and the discharge valve 26 is opened.

1. A liquid medicine dispensing device that dispenses liquid medicine by discharging one or more kinds of liquid medicine from an original drug vial into a prescription bottle, comprising: a rotary unit that rotates while holding a plurality of original drug vials that are arranged in a predetermined direction to invert the plurality of original drug vials together with rotation thereof;a discharge nozzle connected to each original drug vial;a discharge valve capable of opening and closing that is provided in each discharge nozzle;a conveyance mechanism that conveys a prescription bottle in a space on an underside of the rotary unit;detection means that detects a liquid medicine amount discharged into the prescription bottle; andcontrol means that controls driving of the rotary unit, the discharge valves, and the conveyance mechanism, wherein the control means rotates the rotary unit to invert an original drug vial to be discharged until at least liquid medicine discharge begins and also drives the conveyance mechanism to move the prescription bottle to a position directly below the original drug vial to be discharged, and thereafter opens a discharge valve corresponding to the original drug vial to be discharged until a detection value at the detection means reaches a target value, to thereby cause a liquid medicine to be discharged. 2. The liquid medicine dispensing device according to claim 1, wherein the rotary unit comprises: a fixed body;a rotary body that holds a plurality of original drug vials and is also rotatably retained with respect to the fixed body; andan intermediary body provided between the fixed body and the rotary body at an approximately concentric position with respect to a rotational axis of the rotary body;wherein a wire that has one end connected to the rotary body or an original drug vial that is held by the rotary body and another end connected to a fixed member is wound around the intermediary body. 3. The liquid medicine dispensing device according to claim 1, further comprising: an air nozzle that is connected to an original drug vial and that guides air into the original drug vial; anda pump that is connected to the original drug vial through the air nozzle and that pressurizes the inside of the original drug vial. 4. The liquid medicine dispensing device according to claim 3, wherein the pump pressurizes the inside of the original drug vial after rotation of the rotary unit. 5. The liquid medicine dispensing device according to claim 3, further comprising an atmospheric pressure relief valve that is connected to the air nozzle and that opens at a time of liquid medicine discharge to allow a pressure in the original drug vial to return to atmospheric pressure. 6. The liquid medicine dispensing device according to claim 5, further comprising a filter that is provided between the atmospheric pressure relief valve and the original drug vial, and that eliminates contaminants that enter through the atmospheric pressure relief valve. 7. The liquid medicine dispensing device according to claim 3, wherein when the detection value at the detection means reaches the target value, a control section drives the pump to reduce a pressure at the valve and thereby return liquid medicine remaining in the discharge nozzle to the original drug vial. 8. The liquid medicine dispensing device according to claim 1, wherein: the detection means comprise a weighing platform on which the prescription bottle is mounted and which detects a weight of the prescription bottle that is mounted;the conveyance mechanism conveys the prescription bottle together with the weighing platform; andthe control means drives the conveyance mechanism to move the prescription bottle to a discharge position at which a required liquid medicine is discharged based on prescription data that is input by a user, and controls driving of the discharge mechanism based on a detected weight value that is detected with the weighing platform. 9. The liquid medicine dispensing device according to claim 1, further comprising lid detection means that detects the presence or absence of a lid on the prescription bottle that has been set in the liquid medicine dispensing device.
