Can do. If a plurality of upper cassettes 11 are prepared, the upper cassette 11 that has been supplied (handed) with the medicine is replaced with an upper cassette 11 that has been emptied by dispensing the tablets. The medicine supply in the apparatus M can be performed efficiently, and the subsequent packaging work can also be performed efficiently.

  The intrusion prevention member 3 is provided to prevent entry of foreign matter into the medicine supply space portion S in the non-set state in which the upper cassette 11 is removed from the medicine supply space portion S. Although this intrusion prevention member 3 can be in various forms, several embodiments will be exemplified and described below.

  The embodiment shown in FIGS. 1 and 2 is provided with a movable wall portion 31 as the intrusion prevention member 3. The movable wall portion 31 is provided at a position that coincides with the front end portion in the figure when the cassette unit 1 is in a fixed position. The movable wall 31 is in a lying state when the cassette unit 1 is at a fixed position as shown in FIG. 1, and is in a standing state when it is in a pulled-out position as shown in FIG. This is linked with the movement of the cassette unit 1. That is, the movable wall portion 31 is movable between a non-operation position that allows supply of the medicine to the medicine supply space portion S and an operation position that can prevent entry of foreign matter into the medicine supply space portion S. The movable wall portion 31 moves from the non-operating position to the operating position in conjunction with the movement of the cassette unit 1 from the home position to the drawing position. The mechanism for interlocking may be a mechanical mechanism such as a link, or may be an electrical mechanism that operates the movable wall portion 31 in response to sensing by a sensor.

  In the present embodiment, when the cassette unit 1 is in the drawer position, as shown in FIG. 2, the upper part of the medicine supply space S is opened, but the movable wall 31 is in a standing state. Therefore, the movable wall portion 31 becomes a barrier, and when an operator manually supplies the medicine into the medicine dispensing basket 111 of the cassette unit 1 that has been pulled out, the medicine is erroneously put into the medicine supply space section S. It is possible to reduce the possibility that the medicine that has fallen or bounced off the upper cassette 11 is mixed into the medicine supply space S.

  Next, what is shown in FIG. 3 as another embodiment is that the movable plate 34 as the intrusion prevention member 3 is located between the upper cassette 11 and the lower cassette 4 in the medicine supply space portion S. . The movable plate 34 is a single plate-like body provided separately from the shutter 112 of the upper cassette 11, and moves in parallel with respect to the upper cassette 11 and the lower cassette 4 as shown in the figure. Has been. The movable plate 34 is also movable between a non-operation position that allows the supply of medicine to the medicine supply space section S and an operation position that can prevent entry of foreign matter into the medicine supply space section S. The movable plate 34 moves from the non-operating position to the operating position in conjunction with the movement of the cassette unit 1 from the home position to the drawing position.

  Specifically, when the movable plate 34 is in a set state (a state where the upper cassette 11 is positioned in the medicine supply space portion S) and the shutter 112 of the upper cassette 11 is closed, the movable plate 34 is located below the upper cassette 11. Is located. When the shutter 112 is open in the set state, the state is retracted from below the upper cassette 11. Thereby, even when the upper cassette 11 is removed from the cassette unit 1 in the set state, the medicine supply space portion S is covered with the movable plate 34, and the medicine inside the device by the upper cassette 11 and the lower cassette 4 is brought into the state. It is possible to prevent the medicine from being mixed into the medicine supply space S without hindering the supply of the medicine.

  Next, another embodiment shown in FIG. 4 is provided with a movable film 35 as an intrusion prevention member 3. The movable film 35 is a single film-like body formed of a soft resin sheet or the like, and one side on the near side of the figure is fixed to the cassette unit 1. Further, a mechanism capable of winding the movable film 35 in a roll shape is provided on the far side in the drawing (not shown). Therefore, the movable film 35 is interlocked with the movement of the upper cassette 11 in the pulling direction. That is, the movable film 35 is movable between a non-operation position that allows supply of the medicine to the medicine supply space portion S and an operation position that can prevent entry of foreign matter into the medicine supply space portion S. The movable film 35 moves from the non-operating position to the operating position in conjunction with the movement of the cassette unit 1 from the home position to the drawing position. Thereby, when the cassette unit 1 is in the drawer position, the medicine supply space portion S is covered with the movable film 35, so that the medicine can be prevented from being mixed into the medicine supply space portion S.

  Next, in another embodiment shown in FIG. 5A, a fixed wall portion 32 is provided as an intrusion prevention member 3 at the back end portion of the upper cassette 11. In the embodiment shown in FIG. 5B, a groove 33 is provided as an intrusion prevention member 3 at the back end of the upper cassette 11. The fixed wall portion 32 may be formed integrally with the upper cassette 11 or may be used separately from the upper cassette 11 and attached to the upper cassette 11. Although not shown, one upper cassette 1 may be provided with both the fixed wall portion 32 and the groove portion 33.

  The fixed wall portion 32 acts as a barrier for preventing the medicine from being mixed into the medicine supply space portion S due to erroneous injection or rebound of the medicine, like the movable wall portion 31 described above. The groove portion 33 prevents the medicine from being mixed into the medicine supply space portion S by dropping the medicine to be rolled into the medicine supply space portion S, for example.

  As mentioned above, although several types were illustrated and demonstrated about embodiment of the intrusion prevention member 3, what was shown here is an example to the last, Comprising: It can implement with a various form other than that.

  In the above description, the movable plate 34 is a single plate-like body and the movable film 35 is a single film-like body. However, the intrusion prevention member 3 can be formed of various materials regardless of hardness. Further, a combination of a plurality of sheets may be used. Moreover, it is good also as a structure which can be expanded or narrowed by superimposing or folding a plate-shaped object or a film-shaped object.

  Here, when the intrusion prevention member 3 is configured by stacking a plurality of plate-like bodies, for example, a plate-like body in which a plurality of holes are arranged for each sheet is slidably overlapped, It can be considered that the medicine is allowed to pass when the holes overlap, and the medicine cannot pass if the holes do not match. According to this structure, there exists an advantage that the movement distance of the plate-shaped body for opening and closing of a hole can be made small.

  The cover 2 may be used as the intrusion prevention member 3 by interlocking the cover 2 with the cassette unit 1. For example, when the cassette unit 1 is in a fixed position, the cover 2 is movable between a closed position that covers the cassette unit 1 from above and an open position where the cassette unit 1 is exposed. An association mechanism for associating the operation with the cover 2 as the intrusion prevention member 3 is provided, and this association mechanism operates the cover 2 so as to keep the cover 2 in the closed position when the cassette unit 1 is in the drawer position. It is conceivable to regulate this. According to this configuration, since the medicine supply space portion S is covered with the cover 2 in the closed position, mixing of the medicine into the medicine supply space portion S can be prevented.

In the above description, the cassette unit 1 is provided so as to be movable between a fixed position and a drawer position. However, as a reference example , the cassette unit 1 itself is fixed to the medicine supply device M and cannot be pulled out. The upper cassette 11 alone may be detachable from the cassette mounting frame 12 of the cassette unit 1. In this case, the case where the upper cassette 11 is attached to the cassette unit 1 is set, and the case where it is removed is not set.
