It is supported by the peripheral wall 122.

  Since the medicine descending along the first inclined wall 124 is accelerated by gravity, the moving speed is higher than that of the medicine being conveyed along the first inclined wall 124. Accordingly, the distance between the medicine descending along the first inclined wall portion 124 and the medicine before descending along the first inclined wall portion 124 is increased.

  When the first rotating unit 111 is driven, the medicine supported by the second peripheral wall 122 is transported along the second peripheral wall 122. The medicine supported by the second peripheral wall portion 122 moves radially outward while descending along the second inclined wall portion 125 sequentially from the medicine located on the leading side in the rotation direction 2, thereby forming the third medicine. It is supported by the peripheral wall 123.

  Since the medicine descending along the second inclined wall 125 is accelerated by gravity, the moving speed is higher than that of the medicine being conveyed along the second inclined wall 125. Accordingly, the distance between the medicine descending along the second inclined wall 125 and the medicine before descending along the second inclined wall 125 is increased.

  When the second rotating unit 112 is driven, the medicine supported by the third peripheral wall 123 is transported along the third peripheral wall 123. Since the rotation speed of the second rotating portion 112 is higher than the rotation speed of the first rotating portion 111, the distance between the medicine supported by the third peripheral wall portion 123 and the medicine supported by the second peripheral wall portion 122 is increased. Become wider.

  When the medicine supply unit moves with respect to the housing 410, the movement of the medicine supply unit is started after the medicine supply unit is stopped and the opening / closing unit 141 is closed. In this case, it is possible to suppress the discharge of the undesired medicine from the discharge unit 131 during the movement of the medicine supply unit.

  When the supply of the medicine from the medicine supply unit is restarted, the opening / closing unit 141 is opened and the medicine supply unit is restarted. In this case, the medicine can be discharged from the discharge unit 131 immediately after the medicine supply unit is restarted.

Next, the operation of the medicine container 300 attached to the base 200 will be described.
The medicine storage container 300 is driven to rotate about the axis 3 by the rotation of the pair of rollers 281 by the third motor 272.

  When the medicine container 300 is rotated around the axis 3, the medicine in the medicine container 300 is conveyed from the bottom 330 side of the medicine container 300 to the first opening 313 side by the spiral groove 312, and the first opening is formed. It is discharged from the unit 313.

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

  In addition, one medicine container 300 sequentially selected from a plurality of medicine containers 300 is attached to the base portion 200. Each of the plurality of medicine containers 300 is driven under different driving 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 that are small-sized tablets, and special drugs such as capsules, long and thin tablets, spherical tablets, or triangular-pillar tablets. Each of the plurality of medicine containers 300 accommodates a general medicine or a special medicine. When the medicine container 300 is attached to the base unit 200, the control unit 41 to which the detection signal of the identifier 331 from the identification sensor 234 is input through the connection unit 11 is used to control the inside of the medicine container 300 attached to the base unit 200.
