Next, the operation of the drug storage container 300 attached to the base portion 200 will be described.
By rotating the pair of rollers 281 by the third motor 272 , the medicine container 300 is rotationally driven around the axis 3 .

When the drug storage container 300 is rotationally driven around the axis 3, the drug in the drug storage container 300 is transported from the bottom portion 330 side of the drug storage container 300 to the first opening portion 313 side by the spiral groove 312, and the first opening is opened. It is discharged from the part 313 .

The drug discharged from the first opening 313 passes through the connecting conduit 290 of the base portion 200 and is supplied into the drug supply hole 127 of the lid member 120 . The medicines supplied into the medicine supply hole 127 of the lid member 120 are discharged from the discharge part 131 of the medicine supply module 100 one by one.

One drug storage container 300 sequentially selected from a plurality of drug storage containers 300 is attached to the base portion 200 . Each of the plurality of drug storage containers 300 is driven under different drive conditions set based on the identifier 331 . The medicine supply unit is driven corresponding to each of the plurality of medicine containers 300 .

Specifically, the types of drugs include general drugs, which are small-grain tablets, and special drugs, such as capsules, elongated tablets, spherical tablets, and triangular prism-shaped tablets. Each of the plurality of drug storage containers 300 stores a general drug or a special drug. When the medicine container 300 is attached to the base part 200 , the controller 41 receives the detection signal of the identifier 331 from the identification sensor 234 through the connection part 11 , and controls the inside of the medicine container 300 attached to the base part 200 . determine the type of drug contained in the

If the medicine contained in the medicine containing container 300 is determined to be a general medicine, the general medicine discharges a large amount of medicine to the medicine supply part for each amount of rotation of the medicine containing container 300. The control unit 41 stops the rotation of the drug container 300 immediately after the drug replenishment sensor 235 detects that the drug is replenished from the drug container 300 to the drug supply unit. Thereafter, when the drug is no longer detected by the drug replenishment sensor 235, the rotation of the drug container 300 is resumed. As a result, it is possible to prevent the drug from being excessively supplied to the drug supply unit.

When the medicine contained in the medicine container 300 is determined to be a special medicine, the amount of the special medicine that is discharged to the medicine supply unit for each rotation amount of the medicine container 300 tends to decrease.
