Is a value of the height h1 and the width w1 (see FIG. 5) set in advance as possible values.
- the dispensing speed is an example of the driving condition, and is a rotational speed suitable for each medicine information as the rotational speed of the second rotating body 224 when the tablet is dispensed from the variable cassette 22. For example, if the size of the tablet is small, if the rotational speed of the drive motor 242 is high, the tablet is likely to be dispensed excessively until the drive motor 242 stops. On the other hand, if the size of the tablet is large, even if the rotational speed of the drive motor 242 is high, the tablet is not dispensed excessively until the drive motor 242 stops.
- the tablet dispensing speed set as the driving condition that is, the tablet conveyance speed by the second rotating body 224 varies depending on the size of the tablet.
- the dispensing speed when the size of the tablet is large is set to a slower value than the dispensing speed when the size of the tablet is small.
- the payout speed is not limited to the [lock / min] format shown in FIG. 10, but may be stored in a format such as the rotational speed of the second rotating body 224 or the rotational speed of the drive motor 242. .
- the first slowdown and the second slowdown are examples of the driving stop condition, and when the tablet dispensing from the variable cassette 22 is stopped, the rotational speed of the second rotating body 224 is gradually increased. It is the information regarding the execution timing of slowdown that decelerates.

- the second slowdown defines a timing at which the rotational speed of the second rotating body 224 is decelerated from the first rotational speed to a slower second rotational speed. For example, if the shape of the tablet contained in the variable cassette 22 is round and easy to roll, the tablet may roll out and be dispensed after the driving of the second rotating body 224 is stopped.
- the start timing of each of the first slowdown and the second slowdown is set earlier.

- the start timing of the first slowdown and the second slowdown is set as the driving stop condition.
- the rotational speed of the second rotating body 224 is reduced. It is also conceivable that the speed is set as the driving stop condition. For example, for a tablet having a shape such as a sphere that is easy to roll, if the second rotating body 224 is suddenly stopped, there is a risk that it will roll over and be dispensed extra. For this reason, for example, for tablets that are easy to roll, it is conceivable to set the deceleration small.
- the item of the reverse rotation operation is an example of the driving stop condition, and when the tablet dispensing from the variable cassette 22 is stopped, the tablet conveyance direction by the second rotating body 224 is reversed. It is the information regarding the presence or absence of execution of the reverse rotation operation to switch. For example, when the driving of the second rotating body 224 is merely stopped, the tablet remaining on the second rotating body 224 rolls and may be dispensed excessively. The action is set to “Yes”. Thereby, it is possible to prevent extra tablets from being dispensed when the dispensing of the tablets from the variable cassette 22 is stopped. It should be noted that the reverse rotation operation is set to “no” for a tablet that is difficult to roll when the driving of the second rotating body 224 is stopped, and the unnecessary reverse rotation operation is not executed.
- the data structure of the drive correspondence information 122 shown in FIG. 10 is merely an example, and the drive condition defined by the drive correspondence information 122 is stored in the storage unit 12 as one item of the medicine master, for example. It may be what was done.

It is conceivable as another embodiment to shift to the above.
- Step S2 the control unit 11 corresponds to all the medicine information input as medicine information indicating medicines to be dispensed by the prescription data. It is determined whether or not exists. Specifically, the control unit 11 determines, based on the cassette master stored in the storage unit 12, whether or not a tablet not included in each of the fixed cassettes 21 is included in the prescription data as a prescription drug. To do.

In this case, the process can be shifted to step S3.
- pre-assignment excluded medicine information set as medicine information that does not execute assignment to the variable cassette 22 is stored in the storage unit 12. Then, when the control unit 11 does not have the fixed cassette 21 corresponding to the medicine information to be dispensed and the medicine information to be dispensed corresponds to the allotted medicine information, the control unit 11 moves to the variable cassette 22. It is conceivable to display on the monitor 13 that the manual handling unit 4 should be used without executing the assignment. For example, if a tablet with a high possibility of colored powder adhering to the variable cassette 22 is set as the allotment-excluded medicine information, the colored powder adheres to the tablet accommodated in the variable cassette 22 next. Can be prevented.
- the hand-rolling unit 4 should be used for medicines and the like that are not properly dispensed by the variable cassette 22. Whether or not the medicine information to be dispensed corresponds to the allotted medicine information without the control unit 11 determining whether or not the fixed cassette 21 corresponding to the medicine information to be dispensed exists. It can be considered as another embodiment. In this case, when the medicine information to be dispensed corresponds to the allotted medicine information, the control unit 11 indicates that the handing unit 4 should be used without performing the assignment to the variable cassette 22. Displaying on the monitor 13 is also conceivable as another embodiment.

However, in step S64 described later, the edge on the diagonal line of the horizontal contour image M14 is displayed. There is a possibility that the inclination is determined to be large based on the position of the part. Therefore, in step S63, a determination is made to exclude from the inclination determination process in step S64 a flatness that is less likely to cause an inclination of the tablet placed on the medicine placement surface 810A.
