The drive shaft 150 is rotatably fixed inside the peripheral wall 111 while being positioned coaxially with the rotor 120. That is, the drive shaft 150 is rotatably fixed to the medicine storage part 110. The drive shaft 150 rotationally drives the rotor 120 that is detachably mounted in the axial direction. Each of the rotor 120 and the drive shaft 150 is made of resin.

[0026] As shown in Fig. 2, the lid part 130 is rotatably provided so as to open and close the medicine storage part 110.

[0027] As shown in Figs. 2 to 6, the rotor 120 is provided inside the medicine storage part 110 and conveys the medicine stored in the medicine storage part 110 to the discharge port 112 by rotating. The rotor 120 is arranged on the bottom surface of the medicine storage part 110 inside the peripheral wall 111. In the present embodiment, the rotor 120 is configured to be capable of both normal rotation rotating toward one side in the circumferential direction of the rotor 120 as shown by the arrow A in Fig. 3 and reverse rotation rotating toward the other side in the circumferential direction of the rotor 120 as shown by the arrow B in Fig. 3. Note that the rotor 120 does not necessarily need to be capable of both normal rotation and reverse rotation, and it may be rotatable in at least one direction in the circumferential direction of the rotor 120.

[0028] Fig. 7 is a side view showing the positional relationship between the rotor and the partition part included in the cassette provided in the medicine supply device according to an embodiment of the present invention. Fig. 8 is a perspective view showing the appearance of the partition part included in the cassette provided in the medicine supply device according to an embodiment of the present invention. In Fig. 7, a state where the rotor 120 is mounted on the drive shaft 150 is illustrated.

[0029] As shown in FIGS. 3 and 5 to 7, the rotor 120 has a top surface 126 that is convexly inclined upward and a peripheral surface 121 adjacent to the top surface 126. A plurality of groove portions 127 are provided radially on the top surface 126. A cylindrical central protrusion 128 protrudes from the central portion of the top surface 126. A cap portion 160 is attached to the upper end of the central protrusion 128.

[0030] The cap portion 160 in a state where the rotor 120 is attached to the drive shaft 150 and the lid portion 130 in a state where the drug storage portion 110 is closed face each other with a gap therebetween. This gap is 2 mm or less, preferably 1 mm or less.

[0031] As shown in FIGS. 5 and 7, a plurality of first protrusions 122 and a plurality of second protrusions 123 are provided at the lower part of the peripheral surface 121 with a gap 125 therebetween in the circumferential direction of the rotor 120. Each of the plurality of first protrusions 122 and the plurality of second protrusions 123 has a substantially rectangular shape when viewed from the radial direction of the rotor 120. A part of the upper surface of each of the plurality of first protrusions 122 protrudes to a position higher than the lower surface of the partition portion 140. The entire upper surface of each of the plurality of second protrusions 123 is a flat surface. The tips of each of the plurality of first protrusions 122 and the plurality of second protrusions 123 in the radial direction of the rotor 120 face the inner surface of the peripheral wall 111 with a slight gap therebetween.

[0032] Each of the plurality of first protrusions 122 and the plurality of second protrusions 123 is formed so as to be able to press the drug accommodated in the gap 125 and convey it to the discharge port 112 when the rotor 120 rotates. Specifically, the drug accommodated in the gap 125 is conveyed in the circumferential direction of the rotor 120 while being pressed by the first protrusion 122 or the second protrusion 123 as the rotor 120 rotates and falls to the discharge port 112.

[0033] At least two third protrusions 124 are further provided on the circumferential surface 121. As shown in FIGS. 5 and 7, in the present embodiment, one third protrusion 124 is arranged above each of the plurality of second protrusions 123. The tips of at least two third protrusions 124 in the radial direction of the rotor 120 face the inner surface of the peripheral wall 111 with a slight gap therebetween.

[0034] As shown in FIG. 7, a passage G through which the partition portion 140 passes when the rotor 120 rotates is provided between the second protrusion 123 and the third protrusion 124 that are arranged side by side in the vertical direction. The dimension of the width of the passage G in the vertical direction is slightly larger than the dimension of the thickness of the partition portion 140. The third protrusion 124 is formed so as to be able to move the drug located on the partition portion 140 by pressing the drug located on the partition portion 140 when the rotor 120 rotates. Also, as shown in FIG. 7, the first protrusion 122 is formed so as to be able to move the drug located on the partition portion 140 from the partition portion 140 by a part of the upper surface of the first protrusion 122 pushing up the partition portion 140 from below when the rotor 120 rotates.

[0035] As shown in FIGS. 3, 6 to 8, the partition portion 140 is detachably provided on the peripheral wall 111 above the discharge port 112. The partition portion 140 extends from the inner surface of the peripheral wall 111 toward a position above the plurality of first protrusions 122 and the plurality of second protrusions 123 on the circumferential surface 121. A gap 125 communicating with the discharge port 112 is covered by the partition portion 140 to prevent the drug from entering from above.

[0036] In the present embodiment, the partition portion 140 is made of a flexible member. Specifically, as shown in FIGS. 6 to 8, the partition portion 140 is configured by joining a plurality of flexible members to an arcuate base material 141 at intervals along this arc. The flexible member is made of, for example, a soft synthetic resin. In the present embodiment, the partition portion 140 is configured in a brush shape, but is not limited to the brush shape and may be in a plate shape.

[0037] FIG. 9 is a perspective view showing a state in which a partition portion included in a cassette provided in a drug supply device according to an embodiment of the present invention is removed from a drug storage portion together with a partial peripheral wall. As shown in FIG. 9, the base material 141 is attached to a hole portion of a partial peripheral wall 111a that constitutes a part of the peripheral wall 111. The partial peripheral wall 111a is detachably connected to the remaining portion of the peripheral wall 111. Specifically, the partial peripheral wall 111a is detachably attached to the drug storage portion 110 by a snap fit structure.

[0038] The cassette 100 provided in the drug supply device according to an embodiment of the present invention further includes a detaching and attaching mechanism for detachably engaging the drive shaft 150 and the rotor 120. Hereinafter, the configuration of the detaching and attaching mechanism of the cassette 100 provided in the drug supply device according to an embodiment of the present invention will be described.

[0039] FIG. 10 is a cross-sectional view of the rotor and the drive shaft of FIG. 7 as viewed from the direction of the X-X arrow. FIG. 11 is an exploded perspective view showing the configuration of the rotor, the cap portion, and the drive shaft included in the cassette provided in the drug supply device according to an embodiment of the present invention. FIG. 12 is a perspective view showing the appearance of the cap portion included in the cassette provided in the drug supply device according to an embodiment of the present invention. FIG. 13 is a perspective view showing a state in which the rotor is detached from the drive shaft in the cassette provided in the drug supply device according to an embodiment of the present invention. In FIG. 10, the partition portion is not shown.

[0040] As shown in FIGS. 10 and 11, in the present embodiment, the detaching and attaching mechanism includes a magnet 161 and a magnetic body 151. The magnetic body 151 is attached to the tip portion 152 of the drive shaft 150. Specifically, as shown in FIG. 11, a notch portion 152c extending along the axial direction of the drive shaft 150 from the tip of the drive shaft 150 and a through hole 152h extending in a direction orthogonal to the axial direction of the drive shaft 150 are formed in the tip portion 152 of the drive shaft 150.

[0041] As shown in FIG. 10, the magnetic body 151 has a substantially T-shaped configuration including a wide portion and a narrow portion in a longitudinal cross-sectional view, and a through hole is formed in the narrow portion. The narrow portion of the magnetic body 151 is inserted into the notch 152c of the tip portion 152 of the drive shaft 150. With the tip portion 152 of the drive shaft 150 and the wide portion of the magnetic body 151 in contact with each other in the axial direction of the drive shaft 150, the spring pin 153 shown in FIG. 11 is inserted through the through hole 152h of the tip portion 152 of the drive shaft 150 and the through hole of the narrow portion of the magnetic body 151, whereby the magnetic body 151 is attached to the tip portion 152 of the drive shaft 150 as shown in FIG. 10.

[0042] As shown in FIG. 11, the tip portion 152 of the drive shaft 150 and the magnetic body 151 in an assembled state with each other have a hexagonal shape when viewed from the axial direction of the drive shaft 150. The magnetic body 151 is made of a magnetic material such as SUS430.

[0043] The magnet 161 is built in the cap portion 160. Specifically, the cap portion 160 includes a magnet 161, a support portion 162, a cap 163, and a spacer 164. The support portion 162 has a bottomed cylindrical shape and houses and supports the magnet 161 therein. The cap 163 is detachably engaged with the support portion 162. In the present embodiment, the cap 163 and the support portion 162 are engaged with each other by a snap fit structure, but they may be engaged with each other by a screw structure. Each of the support portion 162 and the cap 163 is made of resin. The spacer 164 is sandwiched between the magnet 161 and the cap 163. The spacer 164 has a columnar shape and is formed of resin.

[0044] As shown in FIGS. 10 and 12, in a state where the cap 163 is engaged with the support portion 162, the magnet 161 is fixed together with the spacer 164 in a space surrounded by the cap 163 and the support portion 162. The magnet 161 is made of, for example, a neodymium magnet. As shown in FIG. 11, the cap portion 160 is engaged with a notch 129 formed at the tip of the central protrusion 128 of the rotor 120 and attached to the tip of the central protrusion 128.

[0045] As shown in FIG. 13, the rotor 120 with the cap portion 160 attached to the tip of the central protrusion 128 is detachably attached to the drive shaft 150 in the axial direction of the drive shaft 150. As shown in FIG. 10, in a state where the rotor 120 is attached to the drive shaft 150 in the axial direction of the drive shaft 150, the magnet 161 and the magnetic body 151 are positioned adjacent to each other in the axial direction of the drive shaft 150. In the present embodiment, the bottom of the support portion 162 is located between the magnet 161 and the magnetic body 151.

[0046] In this state, the drive shaft 150 and the rotor 120 are urged in a direction approaching each other along the axial direction of the drive shaft 150 by the magnetic force acting between the magnet 161 and the magnetic body 151. Thus, the detaching mechanism including the magnet 161 and the magnetic body 151 urges the drive shaft 150 and the rotor 120 in a direction approaching each other along the axial direction of the drive shaft and detachably engages them.

[0047] As shown in FIG. 10, a recess 128c that engages with the hexagonal shape of the magnetic body 151 is formed on the shaft hole surface of the rotor 120 through which the drive shaft 150 is inserted. By engaging the tip portion 152 of the drive shaft 150 and the recess 128c of the rotor 120 with each other in the circumferential direction of the drive shaft 150 via the magnetic body 151, the relative position of the rotor 120 with respect to the drive shaft 150 in the circumferential direction of the drive shaft 150 is fixed.

[0048] Hereinafter, the operation of the cassette 100 included in the drug supply device according to an embodiment of the present invention will be described.

[0049] When the rotor 120 rotates with the drug being put into the drug storage portion 110, the drug located on the top surface 126 moves toward the space between the inner surface of the peripheral wall 111 and the peripheral surface 121 of the rotor 120. The plurality of groove portions 127 stir the drug located on the top surface 126 as the rotor 120 rotates, making it easier to move the drug into the above space.

[0050] Of the medicaments that have moved into the above space, some of the medicaments are each received in one of the gaps 125. The medicaments received in the gaps 125 are conveyed in the circumferential direction of the rotor 120 while being pressed against the first protrusion 122 or the second protrusion 123 as the rotor 120 rotates. The medicaments received in the gaps 125 located on the discharge port 112 and communicating with the discharge port 112 fall from the gaps 125 into the discharge port 112 and are discharged.

[0051] At this time, the gap 125 communicating with the discharge port 112 is covered by the partition portion 140, preventing the medicaments from entering from above. As a result, one medicament can be discharged from the discharge port 112 at a time. As a result, each of the plurality of cassettes 100 can supply medicaments within a certain dimensional range of the medicaments to be supplied.

[0052] FIG. 14 is a perspective view showing a state in which, when starting cleaning of a cassette included in a medicament supply device according to an embodiment of the present invention, after removing the partition portion together with the partial peripheral wall from the medicament storage portion, the rotor is removed from the drive shaft. As shown in FIGS. 13 and 14, when cleaning the inside of the medicament storage portion 110, after removing the partition portion 140 together with the partial peripheral wall 111a from the medicament storage portion 110, the rotor 120 is slid and removed from the drive shaft 150 against the biasing force of the attachment / detachment mechanism.

[0053] FIG. 15 is a side view showing a state in which, when finishing cleaning of a cassette included in a medicament supply device according to an embodiment of the present invention, after attaching the rotor to the drive shaft and attaching the partition portion together with the partial peripheral wall to the medicament storage portion, the lid portion is closed. As shown in FIG. 15, after cleaning is completed, the drive shaft 150 is inserted into the shaft hole of the rotor 120, and the rotor 120 is attached to the drive shaft 150 by the biasing force of the attachment / detachment mechanism.

[0054] The cap portion 160 in a state where the rotor 120 is attached to the drive shaft 150 and the lid portion 130 in a state where the medicament storage portion 110 is closed face each other with a gap L therebetween. The gap L is 2 mm or less. Preferably, the gap L is 0.5 mm or more and 1 mm or less.

[0055] In the present embodiment, the magnetic body 151 is attached to the tip portion 152 of the drive shaft 150, and the magnet 161 is attached to the cap portion 160. However, the magnet 161 may be attached to the tip portion 152 of the drive shaft 150, and the magnetic body 151 may be attached to the cap portion 160.

[0056] Further, the detaching and attaching mechanism is not limited to the one that biases the drive shaft 150 and the rotor 120 in a direction approaching each other by magnetic force. For example, like a ball catch, the drive shaft 150 and the rotor 120 may be biased in a direction approaching each other by a spring.

[0057] In the cassette 100 included in the drug supply device according to an embodiment of the present invention, the drug storage unit 110 has a discharge port 112, stores the drug, and discharges the drug from the discharge port 112. The rotor 120 is provided inside the drug storage unit 110 and conveys the drug stored in the drug storage unit 110 to the discharge port 112 by rotating. The drive shaft 150 is rotatably fixed to the drug storage unit 110 while being located coaxially with the rotor 120, and rotationally drives the rotor 120 detachably attached in the axial direction. The detaching and attaching mechanism biases the drive shaft 150 and the rotor 120 in a direction approaching each other along the axial direction of the drive shaft 150 to detachably engage them.

[0058] Thereby, the rotor 120 can be detached from the drive shaft 150 only by moving the rotor 120 in the axial direction of the drive shaft 150, so that the inside of the cassette 100 can be easily cleaned.

[0059] Further, by being biased by the detaching and attaching mechanism, it is possible to suppress the rotor 120 and the drive shaft 150 from engaging incompletely. Furthermore, when the drug is clogged between the circumferential surface 121 of the rotor 120 and the circumferential wall 111, it is possible to suppress the rotor 120 from rising. Also, even when the drug storage unit 110 is in an upside-down state, it is possible to suppress the rotor 120 from falling.

[0060] In this embodiment, the detaching mechanism includes a magnet 161 and a magnetic body 151. Due to the magnetic force acting between the magnet 161 and the magnetic body 151, the drive shaft 150 and the rotor 120 are biased in a direction approaching each other along the axial direction of the drive shaft 150. Thereby, the detaching mechanism can be made into a simple configuration.

[0061] In this embodiment, since the drive shaft 150 and the rotor 120 are engaged with each other in the circumferential direction of the drive shaft 150, the relative position of the drive shaft 150 in the circumferential direction of the drive shaft 150 with respect to the rotor 120 is fixed. Thereby, the rotation of the rotor 120 can be accurately controlled by the rotation of the drive shaft 150.

[0062] In this embodiment, the rotor 120 has a top surface 126 that is convexly inclined upward, and a central protrusion 128 that protrudes from the central portion of the top surface 126. Thereby, the rotor 120 can be detached by gripping the central protrusion 128.

[0063] In this embodiment, a partition portion 140 extending from the inner surface of the peripheral wall 111 toward a position above a plurality of first protrusions 122 and a plurality of second protrusions 123 on the peripheral surface 121 of the rotor 120 is detachably provided with respect to the drug storage portion 110. Thereby, before detaching the rotor 120, the partition portion 140 can be removed from the drug storage portion 110, so that interference between each of the first protrusions 122 and the second protrusions 123 and the partition portion 140 can be prevented. As a result, the detaching of the rotor 120 becomes easy, and the inside of the cassette 100 can be easily cleaned.

[0064] In this embodiment, the lid portion 130 is rotatably provided so as to open and close the drug storage portion 110. The cap portion 160 is attached to the upper end of the central protrusion 128.

As shown in FIG. 26, in the filling instruction screen P3 of the display unit 320 included in the drug supply device according to an embodiment of the present invention, when there is a cassette position 230 where a malfunction has occurred in the drive unit 231 or the RFID reader / writer 232, a selection area T28 corresponding to the cassette position 230 is displayed in an identification color RM.

[0133] The control unit 340 does not display the identification mark T25 in the selection area T28 corresponding to the cassette position 230 where a malfunction has occurred on the filling instruction screen P3.

[0134] As described above, the control unit 340 causes the display unit 320 to display a plurality of selection areas T28 so as to be able to distinguish between the drive unit 231 to which the cassette 100 can be attached and the drive unit 231 to which the cassette 100 cannot be attached.

[0135] In a drug supply device according to an embodiment of the present invention, each of the plurality of cassettes 100 can supply a drug within a certain dimensional range. Each of the plurality of drive units 231 is configured to be able to mount each of the plurality of cassettes 100 and drives the mounted cassette 100. The control unit controls each of the plurality of drive units 231. The control unit assigns drug information regarding the drug to be supplied to the cassette 100 selected according to the dimensions of the drug to be supplied, or to the drive unit 231 to which this cassette 100 is mounted. The control unit controls the drive unit 231 to supply the drug to be supplied from the cassette 100 to which the drug information is assigned, or from the cassette 100 mounted on the drive unit 231 to which the drug information is assigned.

[0136] This enables the operator of the drug supply device to easily set the drug supply device so that drugs within a certain dimensional range can be sub-packaged according to the prescription.

[0137] In the drug supply device according to one embodiment of the present invention, the control unit can receive a selection operation for selecting whether to supply the drug to be supplied from either the cassette 100 or the hand-rolled drug supply cassette 240. This makes it possible to easily determine which of the drugs to be supplied should be supplied from the cassette 100.

[0138] In the drug supply device according to one embodiment of the present invention, when the cassette 100 cannot be mounted in all of the plurality of drive units 231, the control unit does not receive a selection operation for selecting supply from the cassette 100. This suppresses the acceptance of incorrect selection operations.

[0139] In the drug supply device according to one embodiment of the present invention, the control unit does not receive a selection operation for selecting supply from the cassette 100 for drugs that cannot be supplied from the cassette 100. This suppresses the acceptance of incorrect selection operations.

[0140] The drug supply device according to one embodiment of the present invention further includes a display unit 320 capable of displaying information related to the assignment of drug information. This makes it possible to easily determine which drive unit 231 or cassette 100 can be assigned drug information.

[0141] In the drug supply device according to one embodiment of the present invention, the control unit causes the display unit 320 to display the drive unit 231 capable of mounting the cassette 100 and the drive unit 231 incapable of mounting the cassette 100 in a distinguishable manner. This suppresses the mounting of the cassette 100 on the drive unit 231 that cannot mount it.

[0142] In the drug supply device according to one embodiment of the present invention, the control unit causes the display unit 320 to display so as to be distinguishable between drugs that can be supplied from the cassette 100 and drugs that cannot be supplied from the cassette 100. Thereby, it is possible to suppress the incorrect drug from being filled in the cassette 100.

[0143] In the drug supply device according to one embodiment of the present invention, the control unit causes the display unit 320 to display the usage history of the plurality of cassettes 100. Thereby, it becomes possible to determine the necessity of cleaning the cassette 100 and the like.

[0144] In the drug supply device according to one embodiment of the present invention, the control unit causes the display unit 320 to display the identification information of the cassette 100 that last supplied the drug to be supplied. Thereby, it becomes possible to determine the drive unit 231 capable of allocating drug information without cleaning the cassette 100 or the cassette 100.

[0145] In the drug supply device according to one embodiment of the present invention, the control unit causes the display unit 320 to display the required number of fills of the drug to be supplied. Thereby, the operator of the drug supply device can easily grasp the required number of fills.

[0146] In the drug supply device according to one embodiment of the present invention, when the supply number of the drug to be supplied is insufficient, the control unit causes the display unit 320 to display the shortage number of the drug to be supplied. Thereby, the operator of the drug supply device can easily grasp the shortage number.

[0147] In the drug supply device according to one embodiment of the present invention, the control unit collates the drug information with the reading result by the reading unit 330. Thereby, it is possible to suppress the incorrect drug from being filled in the cassette 100.

[0148] In the drug supply device according to one embodiment of the present invention, when the cassette 100 selected according to the dimensions of the drug to be supplied is attached to the drive unit 231, the control unit assigns drug information to this drive unit 231. As a result, the operator of the drug supply device can save the trouble of assigning the drug information of the drug to be supplied using the operation unit 310.

[0149] In the present embodiment, the case where drug information regarding the drug to be supplied is assigned to the drive unit 231 to which the cassette 100 is attached has been described as an example. However, drug information regarding the drug to be supplied may be assigned to the cassette 100 attached to the drive unit 231. Also in this case, the operational effects by the various functions of the drug supply device described above are exhibited.

[0150] Hereinafter, the cassette selector included in the drug supply device according to one embodiment of the present invention will be described. FIG. 27 is a plan view showing the configuration of the cassette selector included in the drug supply device according to one embodiment of the present invention. As shown in FIG. 27, the cassette selector 400 included in the drug supply device according to one embodiment of the present invention has a plate-like shape. The cassette selector 400 can select a cassette 100 capable of supplying a drug from among a plurality of cassettes 100 according to the dimensions of the drug. The operator uses the cassette selector 400 to select a cassette 100 corresponding to the dimensions of the drug from among the plurality of cassettes 100. In other words, the cassette selector 400 is used to select a cassette 100 corresponding to the dimensions of the drug from among the plurality of cassettes 100.

[0151] On the cassette selector 400, a drug shape display column T51, a drug diameter display column T52, and a drug thickness display column T53 are displayed. The drug shape display column T51 is a part for discriminating the drug shape. The drug diameter display column T52 is a part for discriminating the dimensional range of the diameter of the drug. The drug thickness display column T53 is a part for discriminating the dimensional range of the thickness of the drug. By specifying the shape, diameter dimensional range, and thickness dimensional range of the drug while looking at the drug shape display column T51, the drug diameter display column T52, and the drug thickness display column T53 in this order, the cassette 100 capable of supplying the drug can be selected.

[0152] As shown in FIG. 27, in the drug shape display column T51, the planar shape and the side shape of each of a plurality of types of drugs having different shapes are displayed. Thereby, it is possible to determine which type the shape of the drug to be supplied belongs to. In the present embodiment, two types are displayed: type A which is a disk shape (the planar shape is circular and the central portion is not swollen), and type B which is a convex lens shape (the planar shape is circular and the central portion is swollen). Note that the types of drug shapes displayed in the drug shape display column T51 are not limited to two types, and may be three or more types.

[0153] In the drug diameter display column T52, a plurality of first through holes having different diameters are formed in a circular shape for each type of drug shape. In the drug shape of type A, three first through holes H11 to H13 are formed. In the drug shape of type B, four first through holes H11 to H14 are formed.

[0154] For each of the plurality of first through-holes, a dimensional range of the diameter of the drug is displayed. Specifically, in the vicinity of the first through-hole H11, it is displayed that the dimensional range of the diameter of the drug is equal to or less than the dimensional value of the diameter of the first through-hole H11. In the vicinity of the first through-hole H12, it is displayed that the dimensional range of the diameter of the drug is greater than the dimensional value of the diameter of the first through-hole H11 and equal to or less than the dimensional value of the diameter of the first through-hole H12. In the vicinity of the first through-hole H13, it is displayed that the dimensional range of the diameter of the drug is greater than the dimensional value of the diameter of the first through-hole H12 and equal to or less than the dimensional value of the diameter of the first through-hole H13. In the vicinity of the first through-hole H14, it is displayed that the dimensional range of the diameter of the drug is greater than the dimensional value of the diameter of the first through-hole H13 and equal to or less than the dimensional value of the diameter of the first through-hole H14. The dimensional values of the diameters of the first through-holes H11 to H14 are 6 mm, 7 mm, 8 mm, and 9 mm in sequence.

[0155] When the drug is press-fitted in sequence from the first through-hole with the smallest diameter among the plurality of first through-holes H11 to H14, it is possible to determine that the diameter of the drug is within a certain dimensional range based on the dimensional value of the diameter of the first through-hole through which the drug first passes. Specifically, it can be determined that the numerical range displayed in the vicinity of the first through-hole through which the drug first passes is the dimensional range of the diameter of the drug.

[0156] In the drug thickness display column T53, a plurality of second through-holes in the shape of rectangles with different widths are formed for each type of drug shape and each dimension range of the drug diameter. In the case of the A-type drug shape with a diameter dimension of 6.01 mm to 7.00 mm, three second through-holes H21 to H23 are formed. In the case of the A-type drug shape with a diameter dimension of 7.01 mm to 8.00 mm, three second through-holes H31 to H33 are formed. In the case of the B-type drug shape with a diameter dimension of 6.01 mm to 7.00 mm, three second through-holes H41 to H43 are formed. In the case of the B-type drug shape with a diameter dimension of 7.01 mm to 8.00 mm, four second through-holes H51 to H54 are formed. In the case of the B-type drug shape with a diameter dimension of 8.01 mm to 9.00 mm, four second through-holes H61 to H64 are formed. Note that in areas where the shape and diameter dimension range of the drug are outside the scope that can be accommodated in the cassette 100, the second through-holes are not formed and are indicated as not applicable.

[0157] Corresponding to each of the plurality of second through-holes, the dimension range of the thickness of the drug is displayed. Specifically, in the vicinity of each of the plurality of second through-holes, the dimension range of the thickness of the drug is displayed. In the vicinity of the second through-hole H21, it is displayed that the dimension range of the thickness of the drug is equal to or less than the dimension of the width of the second through-hole H21. In the vicinity of the second through-hole H22, it is displayed that the dimension range of the thickness of the drug is greater than the dimension of the width of the second through-hole H21 and equal to or less than the dimension of the width of the second through-hole H22. In the vicinity of the second through-hole H23, it is displayed that the dimension range of the thickness of the drug is greater than the dimension of the width of the second through-hole H22 and equal to or less than the dimension of the width of the second through-hole H23. The dimensions of the widths of the second through-holes H21 to H23 are 1.8 mm, 2.5 mm, and 3.2 mm in sequence.

[0158] When the drug is inserted in order from the second through-holes H21 to H23 having a small width among the plurality of second through-holes, it is possible to determine that the thickness of the drug is within a certain dimensional range based on the width dimension of the second through-hole through which the drug first passes. Specifically, it can be determined that the numerical range displayed in the vicinity of the second through-hole through which the drug first passes is the dimensional range of the thickness of the drug. The plurality of second through-holes H21 to H23 can be used to determine the thickness dimension range of a drug having a drug shape of type A with a diameter dimension of 6.01 mm to 7.00 mm.

[0159] Similarly, the second through-holes H31 to H33 can be used to determine the thickness dimension range of a drug having a drug shape of type A with a diameter dimension of 7.01 mm to 8.00 mm. The second through-holes H41 to H43 can be used to determine the thickness dimension range of a drug having a drug shape of type B with a diameter dimension of 6.01 mm to 7.00 mm. The second through-holes H51 to H54 can be used to determine the thickness dimension range of a drug having a drug shape of type B with a diameter dimension of 7.01 mm to 8.00 mm. The second through-holes H61 to H64 can be used to determine the thickness dimension range of a drug having a drug shape of type B with a diameter dimension of 8.01 mm to 9.00 mm.

[0160] The cassette selector 400 shows the correspondence between the dimensions of the drug and the cassette 100. Specifically, corresponding to each of the plurality of second through-holes, the model number of the cassette 100 capable of supplying the drug is displayed. For example, the model number Aa of the cassette 100 is displayed in the vicinity of the second through-hole H22. This means that the cassette 100 with the model number Aa can supply a drug having a drug shape of type A with a diameter dimension of 6.01 mm to 7.00 mm and a thickness dimension of 1.81 mm to 2.50 mm. Similarly, the model numbers Ab to Ad and the model numbers Ba to Bh are displayed. Note that in a place where the dimensional range of the thickness of the drug is in a category that cannot be accommodated by the cassette 100, the model number of the cassette is not shown in the vicinity of the second through-hole, and "not available" is displayed.

[0161] The cassette identification information of each of the plurality of cassettes 100 also includes the above-mentioned model number. Although the plurality of cassettes 100 are assigned different cassette numbers, there may be a plurality of cassettes 100 with the same model number. In the present embodiment, the RFID tag stores the model number assigned to the cassette 100.

[0162] Figure 28 is a flowchart showing the operation procedure when supplying a drug from a cassette selected according to the dimensions of the drug in a drug supply device according to an embodiment of the present invention. As shown in Figure 28, when supplying a drug from the drug supply device according to an embodiment of the present invention, first, a cassette 100 corresponding to the shape and dimensions of the drug determined using the cassette selector 400 shown in Figure 27 is selected (step S1). Note that the corresponding cassette 100 may be selected from the display of the cassette selector 400 while referring to the shape and dimensions of the drug described in the attached document of the drug.

[0163] Next, the selected cassette 100 is filled with the drug (step S2). Specifically, the cassette 100 with the model number described in the cassette selector 400 is filled with the drug.

[0164] When the cassette 100 filled with the drug is mounted on the drive unit 231, the RFID reader / writer 232 reads the information from the RFID tag attached to the cassette 100 mounted on the drive unit 231, and the control unit 270 assigns drug information including information about the drug to the drive unit 231 (step S3). The drug assignment device according to the present embodiment includes a plurality of cassettes 100, a cassette selector 400, and a control unit 270. Note that the control unit 270 may assign drug information to the cassette 100 filled with the drug.

[0165] The control unit 270 drives the cassette 100 mounted on the drive unit 231 to which the drug information is assigned to supply the drug (step S4). That is, the control unit 270 drives the drive unit 231 so as to supply the drug from the cassette 100 mounted on the drive unit 231 to which the drug information is assigned. When the drug information is assigned to the cassette 100, the control unit 270 drives the cassette 100 to which the drug information is assigned to supply the drug. That is, the control unit 270 drives the drive unit 231 on which the cassette 100 is mounted so as to supply the drug from the cassette 100 to which the drug information is assigned.
