Description

  The present invention relates to a half-tablet cutting device, and more particularly to a tablet in a tablet cassette that is installed in a drug selection and supply device that is installed in a pharmacy such as a hospital and appropriately selects and takes out drugs such as tablets according to a prescription for each patient. The present invention relates to a half-tablet cutting device that can be cut into half-tablets.

  As shown in FIG. 12, the conventional tablet cassette includes a tablet holding rotor 2a in which tablet holding paths 24, 24,... A plurality of drum-shaped support platforms provided on the upper stage are mounted on each stage (see, for example, Patent Documents 1 and 2).

  In such a tablet cassette, the rotation of the motor of the drug selection and supply device is transmitted to the tablet holding rotor 2a via a gear, whereby the tablet holding rotor 2a rotates. Then, in accordance with input data such as a prescription, the tablet held in the tablet holding path 24 covered with a partition plate (not shown) is moved from the tablet discharge path opened directly below the tablet holding path 24 to the lower stage of the drug selection / supply device. To discharge. In the lower part of the medicine selection and supply device, a packaging operation for packaging the discharged tablets one by one with a packaging device (not shown) is performed.

  By the way, when a child is a patient, when a drug is given to the patient, since one tablet is excessive as a single dose, the tablet may be cut into half tablets to make an appropriate amount. Conventionally, in such a case, the tablet was manually cut into half tablets and then filled into a dedicated tablet cassette. However, a normal tablet cassette was mistakenly filled with a half-tablet tablet. There was a risk of it.

  In general, the required quantity of tablets cut into half tablets is less than the required quantity of tablets not cut into half tablets, but for those equipped with left and right support bases on the drug selection and supply device, While setting a tablet cassette filled with ordinary tablets on one support table and setting the dedicated tablet cassette on the other support table, mixing of both tablet cassettes was avoided. Therefore, in spite of the difference in the required quantity, since the same number of both tablet cassettes are prepared, it is necessary to prepare the tablet cassettes roughly, which leads to an increase in the size of the entire apparatus.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a half-tablet cutting device capable of greatly reducing the total number of tablet cassettes by generalizing the tablet cassette. To do.

Since it is provided with a bypass valve that is sometimes closed , the tablet cassette is cut into half tablets within the same tablet cassette, or the tablet cassette is generalized by not cutting the tablet. be able to. Therefore, unlike the conventional case, there is no possibility that a normal tablet cassette is mistakenly filled with a half-cut tablet. In addition, a single type of tablet cassette need only be prepared regardless of the difference in the required quantities of tablets cut into half tablets and tablets not cut into half tablets. Thereby, the whole apparatus can be made compact.

In addition, since the tablet can be cut into half tablets inside the tablet cassette, there is no need to manually cut the tablet into half tablets as before, and the tablet cut into half tablets is used as the tablet cassette. The tablets are not lost when filling. Moreover, since the tablet can be cut almost correctly into a half tablet, the tablet is not crushed and cannot be used. Moreover, since the tablet can be cut immediately before dosing to reduce moisture absorption from the cut surface, it is advantageous in the case of a tablet that dislikes moisture absorption due to its properties. Furthermore, advantages in the present invention, in a state where the cutter member is fixed, such as originally since tablets with only the rotational driving force of the rotary drive by Carlo over the other side is cut by half tablet, its low cut sound There is also.

In addition, the rotation direction of the tablet holding rotor 2 in each figure is counterclockwise as viewed from above, but the rotation direction of the tablet holding rotor 2 can be changed by changing the arrangement of the partition plate 6 and the cutter 7 or the like. It can also be reversed.

  As shown in FIG. 1, FIG. 2 and FIG. 3, the tablet cassette 10 is provided with a tablet storage portion 1 for storing tablets, and is rotatably provided in the tablet storage portion 1 around the vertical axis. A tablet holding rotor 2 in which tablet holding paths 24, 24, ... for holding are formed, and a tablet agitator 3 that is above the tablet holding rotor 2 and can be rotated at a higher speed than the tablet holding rotor 2. And a tablet discharge path 4 for discharging the tablets from the tablet holding paths 24, 24,... And a part of the tablet holding paths 24, 24,. A partition plate 6 to be covered, a cutter (corresponding to a cutter member) 7 which is provided between the partition plate 6 and the tablet discharge path 4 and cuts the tablet into half tablets, a bypass valve 8 and a partition valve 9. It consists of and.

  The tablet storage unit 1 includes a main body upper part 11 and a main body lower part 12. Of these, the main body upper portion 11 is made of, for example, a transparent resin and has a substantially fan shape in plan view, and the front, rear, left and right side walls are each formed of a vertical surface or a downward slope. A lid 13 is attached to the upper part of the main body upper part 11 so as to be openable and closable. A vertical surface 14 is formed at the lower part of the main body upper part 11 so as to surround the tablet holding rotor 2 in particular.

  The main body lower portion 12 is made of, for example, a translucent resin, and has a substantially fan shape in plan view like the main body upper portion 11, and front, rear, left and right side walls thereof are formed with substantially vertical surfaces. A top plate 5a is provided on the upper portion of the lower body portion 12, and the top end of the tablet discharge path 4 is opened in the top plate 5a. A bottom plate 5 is provided at a lower portion of the main body lower portion 12, and the lower end of the tablet discharge path 4 is opened in the bottom plate 5, and rotary shafts 15 and 17 to be described later project coaxially through the bottom plate 5. ing.

  The tablet holding rotor 2 includes a disk-shaped rotor main body 22 that is slightly reduced in diameter on both the upper and lower sides in a state of being attached in the tablet storage unit 1, and a protruding portion 21 that protrudes above the rotor main body 22. A round hole 26 is formed in the center of the protruding portion 21. On the peripheral surface 23 of the rotor main body 22, tablet holding paths 24, 24,... Arranged by dividing the peripheral surface 23 into, for example, 10 parts are recessed toward the center. The tablets dropped between the tablet holding paths 24, 24,... And the vertical surface 14 rotate while being individually held on the top plate 5a, and will be described in detail in a first section 241 and a second section described later in detail. The section 242 and the third section 243 are sequentially conveyed.

  The depth and width of each tablet holding path 24, 24,... Are set according to the size of one tablet that can be held here. Tablets include discs, ellipsoids, and other irregular shapes, and various types of tablets are used. Various types of rotor body 22 are also available depending on the type of tablet. Will be. In the center of the rotor body 22 in the width direction, a groove portion 25 slightly deeper than the depth of each tablet holding path 24, 24,. The width of the groove 25 is set slightly wider than the blade thickness of the cutter 7.

  The tablet holding rotor 2 is fixed to a hollow rotary shaft 15 that penetrates through the position in the front-rear direction and slightly rearward of the upper part 11 and the lower part 12 of the main body 11 of the tablet storage unit 1. A large-diameter gear 16 is fixed to the lower end of the hollow rotary shaft 15. The large-diameter gear 16 is meshed with an upper small-diameter gear among upper and lower gears connected to a motor of a drug selection / supply device (not shown). Therefore, the rotation of the motor is decelerated and transmitted to the tablet holding rotor 2.

  The tablet agitator 3 is in the upper part of the rotor main body 22 of the tablet holding rotor 2 and is loosely fitted to the protruding portion 21 and has a truncated cone shape having an inclined surface that is higher at one peripheral end and lower at the other peripheral end. However, the diameter of the tablet holding paths 24, 24,...

  The tablet agitator 3 is fixed to the upper end of the solid rotary shaft 17 that passes through the hollow rotary shaft 15 and protrudes from the round hole 26 of the protruding portion 21. The solid rotary shaft 17 extends to the lower side of the hollow rotary shaft 15, and a small-diameter gear 18 is fixed to the lower end thereof. The small-diameter gear 18 is meshed with the lower large-diameter gear of the upper and lower double gears. Therefore, the rotation of the motor is increased and transmitted to the tablet agitator 3. As a result, the tablet agitator 3 rotates at a higher speed than the tablet holding rotor 2 and agitates the tablets filled in the tablet storage unit 1, and causes so-called bridging (naturally occurring drug agglomeration). Instead, the tablets that fall along the inclined surface are held one by one in the tablet holding paths 24, 24,.

  The upper part of the tablet discharge path 4 passes through a passage opened directly below the first section 241 and the second section 242 of the tablet holding rotor 2, and the lower part is opened. The passage opened directly below the second third section 243 and the gate valve 9 are joined together. By closing the gate valve 9, a pocket portion 9a is formed between the third compartment and the tablet discharge path.

  The partition plate 6 is formed of a thin plate made of stainless steel, for example, and as shown in FIGS. 2 and 3, the base portion thereof is cantilevered from an appropriate position of the lower body portion 12 of the tablet storage unit 1. . The leading end extends to the upper diameter-reduced portion of the rotor body 22 so as to close the first section 241, the second section 242, and the third section 243. The partition plate 6 can be moved and adjusted in the vertical direction.

  The cutter 7 is formed of, for example, a thin plate made of stainless steel, like the partition plate 6, and its base portion is located at a proper position of the lower body portion 12 of the tablet storage unit 1 as shown in FIGS. 2 and 3. Cantilevered. As shown in FIG. 4, the cutter blade 71, which is the tip of the cutter blade 71, extends into the groove 25 of the rotor body 22 so as to cross the second section 242. As with the partition plate 6, the cutter 7 can be moved and adjusted in the vertical direction.

  The bypass valve 8 is formed of a plate-like member that can move in the lateral direction, and is disposed immediately below the first section 241 and directly above the tablet discharge path 4. The bypass valve 8 is in an open state when the tablet p carried in the state held by the tablet holding path 24 in the first section 241 by the rotation of the tablet holding rotor 2 is discharged from the tablet discharge path 4. On the other hand, when the tablet p is not discharged from the tablet discharge path 4, it operates so as to be in a closed state.

  The gate valve 9 is formed of a plate-like member that can move in the lateral direction similarly to the bypass valve 8, and is disposed below the third section 243, and the tablet holding path 24 in the third section 243. It is interposed in the connection part with the tablet discharge path 4 in the pocket part 9a which stores temporarily the half tablet p1 discharged | emitted from.

  Here, the tablet holding rotor 2 is configured to be able to rotate at a pitch interval shorter than the interval between the two adjacent tablet holding paths 24, 24, and includes the first section 241, the second section 242, and the third section. A compartment 243 is provided. When the tablet holding rotor 2 is sequentially rotated at the pitch interval, the first section 241 is held in the tablet holding path 24 on the lower side of the partition plate 6 and on the upstream side in the rotation direction. The tablets carried in the state are discharged from the tablet holding path 24 to the tablet discharge path 4 with the bypass valve 8 opened, while being held in the tablet holding path 24 on the upstream side in the rotation direction. This is a section for maintaining the state in which the tablet is held in the tablet holding path 24 with the bypass valve 8 closed, for example, the tablet holding path 24c in FIG. 6 (b). The second compartment 242 cuts the tablets, which are carried in the state of being held in the tablet holding passage 24 on the downstream side in the rotation direction, below the partition plate 6 into upper and lower half tablets by the cutter 7. In this section, the lower half tablet is dropped onto the tablet discharge path 4 while the cut upper half tablet remains on the cutter 7, and corresponds to, for example, the tablet holding path 24c in FIG. 6 (c). The third section 243 is a section for dropping the upper half tablet, which is carried in a state held in the tablet holding path 24 further downstream in the rotation direction, below the partition plate 6 to the tablet discharge path 4. For example, the tablet holding path 24c in FIG. 6 (e) corresponds to this.

  FIG. 5 is a control block diagram of the tablet cassette 10. As shown in FIG. 5, the control device 500 of the tablet cassette 10 is disposed close to the medicine selection / supply device for setting the tablet cassette 10 and is electrically connected to the input unit 501, the output unit 502, and the sensor 503. The computer includes a ROM 504, a RAM 505, and a CPU 506 as hardware. The ROM 504 stores a control program for the tablet cassette 10, various preset data, and the like, and the RAM 505 temporarily stores data. The sensor 503 is made of a photo interrupter or the like, and detects a tablet p or a half tablet p2 (or p1) that falls into the tablet discharge path 4 (or the pocket portion 9a) of the tablet cassette 10. The output unit 502 includes an LCD or the like, and displays various messages to the user. The input unit 501 is for inputting various instructions and prescription data of the user.

  The CPU 506 controls the overall operation of the tablet cassette 10 in accordance with a control program stored in advance in the ROM 504. From the viewpoint of its main functions, the CPU 506 calculates a calculation unit 506a, a rotor control unit 506b, a bypass valve. It is comprised from the control part 506c and the gate valve control part 506d.

  Based on the prescription data input from the input unit 501 and the detection signal from the sensor 503, the calculation unit 506a is configured to detect the rotation timing 1 of the tablet holding rotor 2, the opening / closing timing 2 of the bypass valve 8, and the gate valve 9. Are calculated respectively. This timing 2 is a feature of the present invention, and when the tablet p carried in the state held by the tablet holding path 24 by the rotation of the tablet holding rotor 2 is discharged from the tablet discharge path 4, the open state is set. On the other hand, when the tablet p is not discharged from the tablet discharge path 4, it operates so as to be in a closed state. Timing 3 indicates that when the half tablet p1 remaining on the cutter 7 is temporarily stored in the pocket portion 9a, the gate valve 9 is closed, while the half tablet p1 stored in the pocket portion 9a is closed. When discharging to 4, the gate valve 9 operates to open.

  The rotor control unit 506b controls the rotation of the tablet holding rotor 2 in accordance with the timing 1 calculated by the calculation unit 506a. Specifically, in a state where the large and small gears 16 and 18 arranged on the bottom plate 5 side of the tablet cassette 10 are engaged with the two gears 508 and 509 of the motor 507 of the medicine selection and supply device, respectively. The tablet is driven to rotate at a pitch interval shorter than the interval between the tablet holding paths 24, 24,.

  The bypass valve control unit 506c controls the opening / closing operation of the bypass valve 8 according to the timing 2 calculated by the calculation unit 506a. Specifically, the bypass valve 8 connected to the motor 510 can be opened and closed by rotationally driving a motor 510 individually provided in the tablet cassette 10. It should be noted that a solenoid or the like can be used in place of the motor 510, and a link, a rack and pinion or the like can be interposed between the motor 510 and the bypass valve 8, but in any case, the configuration is simple. The detailed configuration is not shown.

  The gate valve control unit 506d controls the opening / closing operation of the gate valve 9 according to the timing 3 calculated by the calculation unit 506a. Specifically, the gate valve 9 connected to the motor 511 can be opened and closed by rotationally driving a motor 511 provided individually in the tablet cassette 10. In addition, it can replace with the motor 511, a solenoid etc. can be used, and a link, a rack & pinion, etc. can be interposed between the motor 511 and the bypass valve 8, but since it becomes a simple structure anyway. The detailed configuration is not shown.

  Hereinafter, the operation around the tablet holding rotor 2 of the tablet cassette 10 will be described. 6 is a conceptual diagram showing an operation principle 1 around the tablet holding rotor 2, FIG. 7 is a plan view showing an operation process 1 around the tablet holding rotor 2, and FIG. 8 is an operation process 2 around the tablet holding rotor 2. FIG. 9 is a perspective view showing an operation process 3 around the tablet holding rotor 2, FIG. 10 is a perspective view showing an operation process 4 around the tablet holding rotor 2, and FIG. 11 is an operation principle 2 around the tablet holding rotor 2. FIG. 6 (a) to 6 (f) and FIGS. 11 (a) and 11 (b) schematically show the tablet holding paths 24, 24,... Viewed from the rear side. The tablet holding paths 24a, 24b, 24c, and 24d are formed from the downstream side in the rotation direction of the tablet holding rotor 2 toward the upstream side.

  First, the positions of the partition plate 6 and the cutter 7 of the tablet cassette 10 are adjusted in accordance with the size (particularly the vertical dimension) of the tablet p to be filled. As a result, even if the size of the tablet to be handled changes, it can be cut into half tablets almost correctly. In particular, in the case of a vertically symmetrical tablet such as a circle or an ellipse, the tablet can be correctly cut into half tablets. It is assumed that the bypass valve 8 and the gate valve 9 are closed in the initial state as shown in FIG.

  Thereafter, the lid 13 of the tablet storage unit 1 is opened, and a predetermined quantity of tablets p is filled in the main body upper portion 11 and then the lid 13 is closed. The tablet cassette 10 filled with the tablets p is set at a predetermined position on an upper drum-shaped support table (not shown). Then, the large and small gears 16 and 18 arranged on the bottom plate 5 side of the tablet cassette 10 mesh with the two gears 508 and 509 of the motor 507 of the medicine selection and supply device, respectively. In this state, it is assumed that prescription data including a half-tablet tablet p1 (or p2) is input from the input unit 501 to the control device 500. Based on the input prescription data and the detection signal from the sensor 503, the calculation unit 506a of the control device 500, based on the timing 1 of the rotation of the tablet holding rotor 2 and the timing 2 of the opening / closing operation of the bypass valve 8, The timing 3 of the opening / closing operation of the gate valve 9 is calculated, and those timing signals are issued to the rotor control unit 506b, the bypass valve control unit 506c, and the gate valve control unit 506d, respectively.

  At this time, since the filled tablet p is on the tablet agitator 3, the rotor controller 506b is agitated by the tablet agitator 3 when the motor 507 is rotated in response to the timing 1 signal. The The motor 507 is driven to rotate at a pitch interval shorter than the interval between the tablet holding paths 24, 24,.

  When the motor 507 is driven to rotate at the pitch interval, the tablet agitator 3 rotates at a high speed in the counterclockwise direction, and the tablet holding rotor 2 rotates at a low speed in the counterclockwise direction. As shown in FIG. It falls individually into the tablet holding paths 24, 24,. At this time, as shown in FIG. 6A, the tablet p is dropped and held in the tablet holding path 24 c not closed by the partition plate 6, but the tablet holding path closed by the partition plate 6. Since the tablet p does not enter 24b, the tablet p does not fall into the tablet discharge path 4 directly below them.

  Subsequently, the tablet p that is dropped and held in the tablet holding path 24c rotates the motor 507 by one pitch in response to a command from the rotor control unit 506b, and as shown in FIG. It comes to contact | abut to the cutter blade 71 of the front-end | tip part. The motor 507 is further rotated by one pitch. At this time, since the interval between the cutter blade 71 and the rotor body 22 of the tablet holding rotor 2 is gradually reduced, the cutter blade 71 gradually bites into the tablet p held in the tablet holding path 24c. In fact, as shown in FIG. 6C, the upper and lower half tablets p1 and p2 are cut. Further, since the groove portion 25 of the rotor main body 22 is set deeper than the tablet holding path 24, the tablet p is in contact with the center of the tablet holding path 24c with the groove portion 25 sandwiched between the upper and lower portions. The cutter blade 71 is pushed out. These make it easy to cut even if the type of tablets to be handled is a hard tablet such as a coated tablet or a sugar-coated tablet.

  Of the cut half tablets p1 and p2, the lower half tablet p2 falls into the tablet discharge passage 4 opened immediately below, as shown in FIG. 6 (c) and FIG. The half tablet p2 dropped into the tablet discharge path 4 is discharged to the lower stage through the tablet discharge path in the drug selection / supply device. The half tablet p2 is detected by the sensor 503 in FIG. 5 while dropping into the tablet discharge path 4.

  On the other hand, of the cut half tablets p1 and p2, the upper half tablet p1 is formed by the cutter blade 71 as shown in FIGS. 6 (d) and 9, even when the motor 507 is further rotated by one pitch. It remains on top. Then, the half-lock p1 remaining on the cutter blade 71 is driven by rotating the motor 507 by another pitch, as shown in FIGS. And fall into the pocket portion 9a that opens directly below. Since the pocket portion 9a is closed by the gate valve 9, the dropped half-lock p1 is temporarily stored here. The half tablet p1 that has fallen into the pocket portion 9a is detected by the sensor 503 in FIG.

  Subsequently, the bypass valve control unit 506c receives the signal at the timing 2 and drives the motor 510 to open the bypass valve 8 as shown in FIG. 6 (f). Then, the tablet p dropped and held in a certain tablet holding path 24 abuts against the cutter blade 71 at the tip of the cutter 7 by rotating the motor 507 by one pitch in response to a command from the rotor control unit 506b. Without falling into the tablet discharge path 4 directly below. Further, the rotor control unit 506b receives the timing signal and repeatedly rotates the motor 507 by several pitches. Then, the tablets p sequentially fall into the tablet discharge path 4. The tablet p dropped into the tablet discharge path 4 is discharged to the lower stage through the tablet discharge path in the drug selection / supply device. This tablet p is also detected by the sensor 503 in the middle of dropping into the tablet discharge path 4, and when it reaches a predetermined quantity, it is packaged together with the upper half tablet p1 by the packaging device into one package.

  Next, the bypass valve control unit 506c receives the signal of the timing 2 and drives the motor 510 to close the bypass valve 8 as shown in FIG. 11A, and the gate valve control unit 506d In response to the timing 3 signal, the motor 511 is driven to open the gate valve 9 as shown in FIG. Then, the half tablet p1 temporarily stored in the pocket portion 9a is dropped into the tablet discharge path 4. The half tablet p1 dropped into the tablet discharge path 4 is discharged to the lower stage through the tablet discharge path in the medicine selective supply device. This half tablet p1 is also packaged in the next package by the packaging device. This package is preferably collected and reused. Thereafter, the gate valve control unit 506d receives the signal of the timing 3 and drives the motor 511 to close the gate valve 9 to return to the initial state.

  As described above, according to the present embodiment, the tablet holding path 24 is arranged immediately below the tablet holding path 24 located on the most upstream side between the partition plate 6 and the tablet discharge path 4, and the tablet holding rotor 2 rotates to hold the tablet. When the tablet p carried in the state held in the path 24 is discharged from the tablet discharge path 4, the tablet p is opened, and when the tablet p is not discharged from the tablet discharge path 4, the tablet p is closed. When the bypass valve 8 is placed across the tablet holding path 24 on the downstream side of the position of the bypass valve 8 between the partition plate 6 and the tablet discharge path 4, and the bypass valve 8 is closed. And the cutter 7 for cutting the tablet p carried in the state held in the tablet holding path 24 by the rotation of the tablet holding rotor 2 into half tablets p1 and p2, so that the inside of the same tablet cassette 10 Tablet p is half tablet p1 (or p2 Cut into, or by not cutting the tablet p, it is possible to generalize the tablet Casetta 10. Therefore, unlike the conventional case, there is no possibility of mistakenly filling the normal tablet cassette 10 with the tablet cut into the half tablet p1. Moreover, since the tablets p1 and p2 cut into half tablets and the difference between the required quantities of the tablets p not cut into half tablets need only be prepared for a single type of tablet cassette 10, the total number is small. I'll do it. Thereby, the whole apparatus can be made compact.

  In addition, since the tablet p can be cut into half tablets p1 and p2 inside the tablet cassette 10, there is no need to manually cut the tablets into half tablets as before, and this half tablet was cut. The tablet is not lost when the tablet is filled in the tablet cassette. And since it can cut into half tablets p1 and p2 almost correctly, the tablet p is not crushed and cannot be used. Further, since the tablet p can be cut immediately before dosing to reduce moisture absorption from the cut surface, it is advantageous in the case of the tablet p that dislikes such moisture absorption. Further, since the tablet cassette 10 is cut into half tablets p1 and p2 only with the rotational driving force on the side of the tablet holding rotor 2 that is originally rotationally driven in the state where the cutter 7 is fixed, There is also an advantage that the cut sound is low.

  In the above embodiment, the closed state of the bypass valve 8 is set as the initial state, but the open state may be set as the initial state. In that case, after sending a predetermined amount of tablets p to the packaging device, half tablets p2 are sent and packaged in one package, but in any case, packaging according to prescription data is possible. Of course.

  Moreover, in the said embodiment, although the tablet cassette 10 illustrated the thing of substantially fan shape in planar view, this is equipped with the drum-shaped support stand in the upper stage of the said chemical | medical agent selection supply apparatus, and is set to this support stand. It is because it was made to correspond to what to do. Therefore, if the support base is in the shape of a shelf extending left and right, the shape of the tablet cassette 10 may be rectangular correspondingly.

  Moreover, in the said embodiment, although the tablet holding | maintenance rotor 2 of the tablet cassette 10 is rotationally driven by the motor 507 of the said chemical | medical agent selection supply apparatus, using the motor built in the tablet cassette 10 separately from the motor 507, The tablet holding rotor 2 may be driven to rotate. However, in order to increase the number of sets by downsizing the tablet cassette 10, it is preferable to use an external motor as described above.

  In the above embodiment, the bypass valve 8 and the gate valve 9 are opened and closed by separate motors 510 and 511, respectively. However, since both operations are reverse operations, both the motors 510 and 511 are operated. Can also be used.

  Moreover, in the said embodiment, the tablet holding path 24, 24, ... is each recessedly provided in the surrounding surface 23 of the rotor main body 22 toward the center, and each tablet holding path 24, 24, ... The depth and width of the tablet are set according to the vertical dimension of one tablet that can be held here, but the tablet holding paths 24, 24,... A plurality of round holes may also be used.
