Description

  The present invention relates to a medicine stock structure of a dispensing device, and in particular, a packaged tablet called a PTP (press-through package) tablet sheet is loaded into a medicine stock portion of a tablet cassette of a dispensing device for automatically dispensing in a tablet cassette. It is suitable for the structure to do.

  Traditionally, pharmacists perform dispensing work in pharmacies such as hospitals according to doctors' prescriptions, but in general hospitals where medical fields are wide, there are many types of tablets that can be taken out at all times, and storage locations are limited. Not only was it necessary, but the work of dispensing based on prescriptions was very mentally and physically burdensome.

  Therefore, a dispensing device has been developed that automatically dispenses a predetermined number of predetermined tablets including a fraction of a PTP tablet sheet based on a preset program (see, for example, Patent Documents 1 and 2). The PTP tablet sheet is a packaging form in which the tablet is taken out by breaking the bottom aluminum sheet part by pressing the tablet side. Generally, 10 or more tablets are made into one sheet. Supplied.

  Here, the tablet cassette on which a plurality of PTP tablet sheets are placed is housed in a cassette shelf, and the claw portion of the chucking device mounted on the head device is directly in the groove formed on the front surface of the tablet cassette. Intrusion and relative positioning are performed, and the PTP tablet sheet at the lowest position in the tablet cassette is chucked and taken out to the outside.

  In this tablet cassette 1000, as shown in FIG. 16, the width regulating member 1011 regulates the width direction of the PTP tablet sheet, while the front wall body 1020, the rod body 1041 and the rod body base 1042 are fixed to the cassette base. The object 1040 regulates the longitudinal direction of the PTP tablet sheet.

  In the above-described prior art, the tablet cassette 1000 is fixed to the cassette shelf 1300 in a state where the PTP tablet sheet stacking unit is integrated with the main body.

  However, since there are usually a plurality of cassette shelves 1300 that store the tablet cassettes 1000, the upper cassette shelf 1300 is obstructive, and the PTP tablet sheet can be replenished or removed from above the tablet cassette 1000. There are cases where it is impossible.

  Therefore, it is desired to replenish and take out the PTP tablet sheet from the back of the tablet cassette 1000. At this time, the integrated body 1040 of the rod body 1041 and the rod body base 1042 becomes an obstacle, and the PTP tablet sheet is replenished and removed. It was difficult to work.

  In particular, when adjacent tablet cassettes are installed in close contact with each other on the cassette shelf 1300, the adjacent tablet cassette 1000 is in the way, and replenishment and removal of PTP tablet sheets from a specific tablet cassette 1000 is performed. It was more difficult.

  This invention is made | formed in view of such a situation, and it aims at providing the chemical | medical agent stock structure of the dispensing apparatus which can perform the replenishment or taking-out operation | work of a PTP tablet sheet easily.

It is a sectional side view which shows the state accommodated in the upper predetermined position. In the following, the side of the tablet cassette 500 that faces the chucking unit 400 is referred to as the front, and the opposite side is referred to as the rear.

  The tablet cassette 500 in the present embodiment is formed to be slightly wider than various PTP tablet sheets (corresponding to tablet sheets) 900, 900,... Stacked as shown in FIGS. Yes. Therefore, as the tablet cassette 500, a plurality of tablet cassettes having different width dimensions according to the widths of the various PTP tablet sheets 900, 900,. As shown in FIGS. 2 and 3, the specific configurations thereof are a long cassette base 510 having a concave cross section, and are detachably fitted by sliding in the longitudinal direction of the cassette base 510. It consists of a cassette body 520.

  On the back side of the bottom plate 5101 of the cassette base 510, protrusions (not shown) are formed on the front and rear (and left and right), respectively, and the rear end of the bottom plate 5101 is bent upward and has elastic left and right tongue pieces 5102, 5102. Is formed. A support member 5103 having a reverse concave shape in cross section is formed on the surface side of the rear portion of the bottom plate 5101, and left and right two tongue pieces 515 and 515 that are cantilevered by the support member 5103 are respectively formed so as to be lowered toward the front portion. Has been. As shown in FIG. 2, the tongue pieces 515 and 515 are both disposed in the left and right walls 516 and 517 of the cassette base 510, and the tongue pieces 515 and 515 are used for the PTP tablet sheets 900, 900, A fraction of ... is chucked. However, the number of strips of the tongue piece 515 is not limited to two but may be one or three or more (this is the same for other tongues 5102 and the like).

  The cassette body 520 can further stack a plurality of PTP tablet sheets 900, 900,..., And has a body upper portion (corresponding to a drug stock portion) 530 having a sheet outlet in an open state at the lower portion of the front wall. The main body lower portion 540 is integrally attached to the lower portion of the main body upper portion 530, and a support portion (corresponding to a rail member) 5110 that slidably supports the main body lower portion 540 on the cassette base 510. ing.

  The support portion 5110 is formed by bending both left and right ends of a bottom plate 5111 extending forward and backward to form left and right side walls, and slide rails 5112 and 5112 formed by bending the left and right side walls into a symmetrical U-shape. A tongue piece 5115 provided at the front part of the bottom plate 5111 and formed so as to be lowered toward the rear; and two left and right tongue pieces 5116 and 5116 provided at the rear part of the bottom plate 5111 and directed upward therefrom. It has become. A concave notch 5117 is formed at the front end of one of the slide rails 5112 and 5112 (for example, the right side in FIG. 2 and the left side in FIG. 3). The support portion 5110 is fixed to the ceiling surface 5104 of the cassette base 510.

  The main body lower portion 540 is fitted between the slide rails 5112 and 5112 of the support portion 5110 so as to be slidable in the front-rear direction. However, when viewed as a single unit, as shown in FIG. On the bottom surface 541 having a shape, a link mechanism 550 for sequentially taking out a PTP tablet sheet (not shown) stacked at the bottom of the upper part 530 of the main body and a sheet pop-out prevention mechanism 5401 are provided.

  As shown in FIG. 4, the sheet pop-out prevention mechanism 5401 includes an L-shaped main body member 5402 in a side view and a support member 5404 that rotatably supports the main body member 5402 around an axis 5403. ing. Further, the main body member 5402 is elastically biased by a spring 5405 so that the main body member 5402 can be rotated clockwise (A direction in FIG. 4) toward the support member 5404 fixed to the main body lower portion 540 of the tablet cassette 500. Has been.

  Then, as shown in FIG. 5, the upper part 530 of the tablet cassette 500 slides on the slide rail 5112 of the support part 5110 together with the lower part 540 and protrudes to the rear of the cassette base part 510 (overhangs). In the state, the front and rear ends of the body member 5402 of the sheet pop-out mechanism 5401 are on the rear end side on the slide rail 5112. Accordingly, the reaction force received from the slide rail 5112 at this time restricts the rotation of the main body member 5402. Thereby, since the PTP tablet sheet is prevented from jumping forward from the sheet outlet when the PTP tablet sheet is replenished to the main body upper part 530, the replenishment is facilitated.

  Meanwhile, until the main body upper portion 530 of the tablet cassette 500 slides on the slide rail 5112 of the support portion 5110 together with the lower body portion 540, the main body upper portion 530 is completely accommodated on the cassette base 510. Both the front and rear ends of the main body member 5402 of the sheet jumping mechanism 5401 slide along the slide rail 5112. Accordingly, the reaction force received from the slide rail 5112 at this time restricts the rotation of the main body member 5402. This prevents the PTP tablet sheet replenished in the upper body portion 530 from jumping forward from the sheet outlet, thereby increasing the slide speed and improving the working efficiency. Then, as shown in FIG. 6, the main body upper portion 530 of the tablet cassette 500 slides on the slide rail 5112 of the support portion 5110 together with the main body lower portion 540, and the main body upper portion 530 is completely accommodated on the cassette base 510. In this state, only the front end of the main body member 5402 of the sheet pop-out mechanism 5401 exists above the notch portion 5117 of the slide rail 5112. At this time, since the reaction force received from the slide rail 5112 is completely eliminated, the upright state is maintained by the elastic biasing force of the spring 5405. Therefore, if the PTP tablet sheet 900 loaded at the bottom of the upper part 530 of the main body is to be cueed by the action of the link mechanism 550 of the lower part 540 of the main body, the PTP tablet sheet 900 to be cueed The leading end comes into contact with the vicinity of the top of the main body member 5402 of the sheet pop-out mechanism 5401.

  Then, against the elastic biasing force of the spring 5405, the main body member 5402 rotates forward (in the opposite direction to the A direction in FIG. 4), and the PTP tablet sheet 900 loaded at the bottom is moved. The head is cued from the sheet outlet. The cueed PTP tablet sheet 900 can be easily pulled out by being gripped by the chuck 430 of the chucking unit 400.

  Further, a part from the front of the bottom surface 541 of the lower body portion 540 is partially cut out, and the tongue piece 5115 is fitted into the cutout portion (corresponding to a fitting hole) 547 as shown in FIG. By combining, the main body lower part 540 is in a so-called locked state at a position on the front end side in the slide range (a function as a locking means).

  As shown in FIG. 5, this locked state is easily released by pulling out the lower body portion 540 rearward so that the tongue piece 5115 escapes from the cutout portion 547 (this is also a function as a locking means). ).

  Further, two screw holes 548 and 548 are formed at positions spaced apart in the width direction of the bottom surface 541 at the rear of the cutout portion 547 of the bottom surface 541 of the main body lower portion 540. Screws 545 and 545 are screwed to 548 so that the tip portions protrude from the back side of the bottom surface 541 (corresponding to projecting pieces). As shown in FIG. 5, the position of the rear end side in the sliding range of the main body lower portion 540 is regulated by the tip portions abutting on the tongue pieces 5116 and 5116 (function as a stopper means). Is).

  The main body upper part 530 is fixed to the main body lower part 540. When assembled to the cassette base 510 of the cassette main body 520 via the main body lower part 540 and the support part 5110, the main body upper part 530 extends from the rear part to the intermediate part. Is arranged in the left and right side walls 516 and 517 of the cassette base 510 so as to be able to protrude and retract, and has an L-shape in side view that protrudes above the left and right side walls 516 and 517 of the cassette base 510 from its middle part to the front part. The left and right side walls 5311 and 5312 thus protruded are bent inward from each other at the front end so as to face each other with a predetermined gap therebetween, thereby forming a front wall 531. The upper ends of the left and right side walls 5311 and 5312 are connected to each other by a reinforcing plate 532.

  A bar-like member 533 is erected on the rear part of the upper part 530 of the main body, and is laid down when the PTP tablet sheets 900, 900,... Are filled, so that the PTP tablet sheet 900, The PTP tablet sheets 900, 900,... Are aligned by raising the rod-like member 533 while sandwiching 900,. A rectangular hole 5302 formed in front of the bottom surface 5301 of the main body upper part 530 is for inserting the screws 545 and 545.

  Hereinafter, the usage method of the tablet cassette 500 of the dispensing apparatus 1 is demonstrated roughly.

  Here, FIG. 7 is a perspective view showing a state in which a plurality of tablet cassettes 500 are mounted on the shelf plate 602 of the cassette shelf 600, and FIG. 8 is a state in which the main body upper part 530 of the specific tablet cassette 500 is pulled out rearward. FIG. 9 is a perspective view showing the state of the tablet cassette 500 in the state of FIG. 7 before cueing the sheet, and FIG. 10 is the state after cueing of the sheet of the tablet cassette 500 in the state of FIG. FIG.

  7, a large number of tablet cassettes 500, 500,... Are mounted on the shelf plate 602 of the cassette shelf 600. As shown in FIG. In this case, the adjacent tablet cassettes 500 and 500 are in the way, and for example, it is difficult to replenish or take out the PTP tablet sheet 900 from the specific tablet cassette 500 at the center in FIG.

  Therefore, as shown in FIG. 8, the main body upper portion 530 of the tablet cassette 500 and the main body lower portion 540 are pulled out rearward of the cassette base 510, and the rod-shaped member 533 is laid backward. At this time, as a result of the tongue piece 5115 escaping from the cutout portion 547 simply by performing the pull-out operation, the locked state is easily released.

  Further, while the upper part 530 of the main body of the tablet cassette 500 is slid and pulled backward, the PTP tablet sheet 900 is dropped from the sheet outlet which is the front opening by the function of the sheet pop-out prevention mechanism 5401. Is prevented.

  That is, the sheet pop-out prevention mechanism 5401 is restricted in rotation by the slide rail 5112 of the support portion 5110 while the main body member 5402 is slid, and the top portion is the bottom of the upper main body 530 of the tablet cassette 500. The PTP tablet sheet 900 is elastically biased so as to come into contact with the front end of the PTP tablet sheet 900 loaded on the table, and maintains an upright state. Therefore, in this state, the PTP tablet sheet 900 is placed on the lower part of the front wall of the upper body 530 of the tablet cassette 500. It does not jump out of the seat exit.

  When the rod-like member 533 is laid backward, the main body upper part 530 is opened rearward, and the PTP tablet sheet 900 can be easily replenished or taken out from the opened main body upper part 530.

  Thereafter, the rod-shaped member 533 is raised again to push the main body upper portion 530 of the tablet cassette 500 back forward. At this time, the main body upper portion 530 of the tablet cassette 500 is slid and pushed back forward. The function of the sheet pop-out prevention mechanism 5401 prevents the PTP tablet sheet 900 from dropping out from the sheet outlet, which is the front opening.

  That is, the sheet pop-out prevention mechanism 5401 has the body member 5402 whose rotation is restricted by the slide rail 5112 of the support portion 5110 during the slide, and the top portion of the mechanism 5401 is the upper portion of the tablet cassette 500. Since the PTP tablet sheet 900 is elastically biased so as to abut against the front end of the PTP tablet sheet 900 stacked at the bottom of the 530 and is maintained in an upright state, the PTP tablet sheet 900 is in the upper part 530 of the tablet cassette 500 in this state. It will not jump out of the seat exit at the bottom of the front wall.

  When the main body lower portion 540 together with the main body upper portion 530 slides on the slide rail 5112 of the support portion 5110 and reaches the front end thereof, the tongue piece 5115 is fitted into the cutout portion 547, so that the locked state can be easily achieved. Become. The state at this time is as shown in FIG.

  That is, at this time, the main body member 5402 of the sheet pop-out prevention mechanism 5401 also reaches above the notch portion 5117 at the front end of the slide rail 5112, so that the reaction force received from the slide rail 5112 of the main body member 5402 is completely eliminated. The main body member 5402 is maintained in an upright state by the elastic biasing force of the spring 5405.

  As shown in FIG. 1, the chucking unit 400 includes a Z carriage 411 extending forward (Z direction in FIG. 1) from the carriage body 310, a rotary solenoid 420 disposed on the Z carriage 411, and the rotary solenoid 420. Chuck 430 driven by the horizontal axis, horizontal guides 440 and 440 respectively disposed on the left and right sides of the chuck 430, a primary bucket 450 provided at a lower portion between the horizontal guides 440 and 440, and a front portion of the primary bucket 450 A line sensor 460 provided and a secondary bucket 480 with a shutter 470 provided below the primary bucket 450 are provided. The Z carriage 411 is composed of a servo motor (not shown), a ball screw, and a nut.

  If it is not necessary to punch the fraction of the PTP tablet sheet 900, the chuck 430 of the chucking unit 400 moves forward in response to an operation command from a controller (not shown), and the chuck 430 directly uses the tablet cassette. By pressing the pressing member 543 of 500, the pushing member 546 is moved forward by the function of the link mechanism 550.

  By pressing the rear end of the PTP tablet sheet 900 loaded on the lowermost side of the tablet cassette 500 with the moved extruding member 546, the front end of the PTP tablet sheet 900 slightly protrudes from the tablet cassette 500. The so-called cueing is performed, but if the PTP tablet sheet 900 loaded at the bottom is to be cueed by the action of the link mechanism 550 of the main body lower part 540, this cueing is attempted. The tip of the PTP tablet sheet 900 comes into contact with the vicinity of the top of the main body member 5402 of the sheet pop-out mechanism 5401 at a right angle.

  Then, against the elastic biasing force of the spring 5405, the main body member 5402 rotates forward (in the opposite direction to the A direction in FIG. 4), and the PTP tablet sheet 900 loaded at the bottom is moved. The head is cued from the sheet outlet.

  As a result, as shown in FIG. 10, the PTP tablet sheet 900 stacked on the upper part 530 of the main body protrudes from the lowermost side, so that the protruding PTP tablet sheet 900 is chucked by the chuck 430 of the chucking unit 400. You will be able to king.

  Then, the chucked PTP tablet sheet 900 is chucked by the chuck 430 and pulled forward, and the chucking by the chuck 430 is released in order to drop the pulled PTP tablet sheet 900 into the primary bucket 450. To do. The primary bucket 450 is moved onto the secondary bucket 480 using the X carriage 300 and the Y carriage 200. Then, a bottom shutter (not shown) of the primary bucket 450 is opened, and the PTP tablet sheet 900 is dropped into the secondary bucket 480. Next, the bottom shutter 470 of the secondary bucket 480 is opened, and the PTP tablet sheet 900 is dropped onto the transport conveyor unit 800.

  The cutting unit 700 includes a vertical blade and a horizontal blade (not shown) for punching out the fraction of the PTP tablet sheet 900. Even when it is necessary to punch out the PTP tablet sheet 900, as described above, the pressing member 543 of the tablet cassette 500 is pressed by the chuck 430 of the chucking unit 400 and the pushing member 546 is directed forward by the link mechanism 550. Move to.

  By pushing the rear end of the PTP tablet sheet 900 loaded on the lowermost side of the tablet cassette 500 with the moved pushing member 546, the PTP tablet sheet 900 is cued. The chucked PTP tablet sheet 900 is chucked by the chuck 430 and pulled forward, and this time, the pulled PTP tablet sheet 900 is transported to the cutting unit 700 while being chucked. Then, the PTP tablet sheet 900 is punched by using the vertical blade and the horizontal blade, and the PTP tablet sheet 900 corresponding to the punched fraction is dropped directly onto the transport conveyor unit 800.

  The remaining part of the PTP tablet sheet 900 that has been punched out is returned to the original tablet cassette 500 while being chucked by the chuck 430. In this case, the remaining part of the PTP tablet sheet 900 is the tongue of the cassette base 510. It is inserted and stored in the remaining storage section 515a below the pieces 515, 515 in a cueing state.

  The remaining portion of the PTP tablet sheet 900 stored in the remaining storage portion 515a is then chucked by the chuck 430 with the remaining portion of the PTP tablet sheet 900 and pulled forward, and is formed by the line sensor 460. Check. Then, when it is not necessary to punch out the remaining part of the PTP tablet sheet 900, the chucking by the chuck 430 is released in order to drop the remaining part of the PTP tablet sheet 900 into the primary bucket 450. The primary bucket 450 is moved onto the secondary bucket 480 using the X carriage 300 and the Y carriage 200. Next, a bottom shutter (not shown) of the primary bucket 450 is opened, and the PTP tablet sheet 900 is dropped into the secondary bucket 480. Next, the bottom shutter 470 of the secondary bucket 480 is opened, and the PTP tablet sheet 900 is dropped onto the transport conveyor unit 800.

  On the other hand, even when it is necessary to punch the remaining fraction of the remaining portion of the PTP tablet sheet 900, as described above, the chuck 430 can cue it from the remaining portion storage portion 515a under the tongue pieces 515 and 515 of the cassette base 510. The remaining portion of the PTP tablet sheet 900 is chucked and pulled forward. The remaining portion of the pulled PTP tablet sheet 900 is conveyed to the cutting unit 700 while being chucked. Then, the remaining part of the PTP tablet sheet 900 is punched using the vertical blade and the horizontal blade, and the PTP tablet sheet 900 corresponding to the further punched part is dropped directly onto the transport conveyor unit 800.

  On the other hand, the remaining part of the PTP tablet sheet 900 that has been subjected to the further fraction punching is returned to the original tablet cassette 500 while being chucked by the chuck 430. Are inserted and stored in the remaining storage portion 515a below the tongue pieces 515, 515.

  In this way, the PTP tablet sheet 900 loaded on the tablet cassette 500 is dispensed to its fraction without waste.

  The conveyor unit 800 includes a group of rollers 801 and tablet takeout buckets 802 and 802 that are moved in the front-rear and left-right directions by the group of rollers 801. Then, the PTP tablet sheet 900 dropped from the secondary bucket 480 via the shutter 470 or its remaining part is moved in the front / rear / left / right direction by a roller group 801 and dropped into one of the tablet takeout buckets 802 and 802. It is like that.

  On the other hand, the remaining portion or further remaining portion of the PTP tablet sheet 900 dropped from the cutting unit 700 is similarly moved in the front-rear and left-right directions by the roller group 801 and dropped into one of the tablet take-out buckets 802 and 802.

  In this way, the dispensed buckets 802 and 802 accommodate the dispensed PTP tablet sheet 900 or the remainder thereof.

  According to this embodiment, since the tablet cassette 500 is provided with the support portion 5110 that slidably supports the main body upper portion 530 together with the main body lower portion 540 in the front-rear direction, the drug stock portion that is the main body upper portion 530 of the tablet cassette 500 Can be slid in the front-rear direction to be brought away from the cassette base 510 to some extent. Therefore, even if there are a plurality of shelf plates 602 of the cassette shelf 600 in which the tablet cassette 500 is stored, the upper portion 530 of the main body 530 is slid in the front-rear direction of the tablet cassette 500 to avoid the shelf plate 602 of the cassette shelf 600 thereabove. it can. For this reason, it becomes possible to easily replenish and take out the PTP tablet sheet 900 from above the tablet cassette 500.

  In particular, even when the adjacent tablet cassettes 500 and 50 are installed in close contact with each other on the shelf plate 602 of the cassette shelf 600, by sliding the main body upper part 530 in the front-rear direction of the tablet cassette 500, The matching tablet cassettes 500, 500 do not get in the way, and the PTP tablet sheet 900 can be easily replenished or removed from the specific tablet cassette 500.

  In the above embodiment, the two cassette shelves 600 and 600 are arranged on the left and right. However, the cassette shelves 600 and 600 may be arranged on the front and back, or one or three or more cassette shelves may be arranged. Good. In that case, it is preferable from the viewpoint of work efficiency that the number of carriages, chucking units, cutting units, and the like correspond to this.

  Further, in the above embodiment, the sheet pop-out prevention mechanism 5401 has the main body member 5402 whose upper part is forwardly lowered as shown in FIG. 4, but instead, as shown in FIG. Further, it is possible to use a sheet pop-out preventing mechanism 5401a having a main body member 5402a whose upper part is rearwardly lowered. According to this sheet pop-out prevention mechanism 5401a, if the PTP tablet sheet 900 stacked at the bottom of the upper part 530 of the tablet cassette 500 is to be cueed by the action of the link mechanism 550 of the lower part 540 of the main body, The leading end of the PTP tablet sheet 900 to be cued comes into contact with the vicinity of the top of the main body member 5402a of the sheet pop-out mechanism 5401a at an obtuse angle. Therefore, compared with the case where the sheet preventing mechanism 5401 is in contact with the vicinity of the top of the main body member 5402 at a right angle, the headed PTP tablet sheet 900 can easily rotate the main body member 5402a.

  Further, when the PTP tablet sheet 900 passes through the main body member 5402a of the sheet pop-out prevention mechanism 5401a, the corner portion is an obtuse angle, so the main body member 5402 of the sheet pop-out prevention mechanism 5401 having a right-angle corner portion is attached to the PTP. Compared with the case where the tablet sheet 900 passes, the PTP tablet sheet 900 is hardly damaged.

  Further, in the above embodiment, as shown in FIG. 2, the main body upper portion 530 includes left and right side walls 5311 and 5312 that are partially cut out from the rear end toward the front. The body upper part 530 is slid and pulled rearward, and a PTP tablet sheet (corresponding to a medicine) 900 is carried from the notched portions of the left and right side walls 5311 and 5312 of the body upper part 530, and the left and right sides By guiding with the walls 5311 and 5312, it becomes easier to replenish the PTP tablet sheet 900 into the main body upper part 530 of the tablet cassette 500. Further, it becomes easier to take out the PTP tablet sheet 900 replenished to the tablet cassette 500 from the cutout portions of the left and right side walls 5311 and 5312 to the outside of the main body upper portion 530 of the tablet cassette 500.

  However, as shown in FIGS. 12 and 13 (in which the rod-like member 533 is omitted in FIG. 12), the upper ends P and Q of the remaining portions where the left and right side walls 5311 and 5312 are cut out are parallel to the PTP tablet sheet 900. In this case, the PTP tablet sheet 900 and the upper ends P and Q of the remaining part are in line contact. For this reason, either one of the left and right sides of the PTP tablet sheet 900 rides on the upper ends P and Q of the remaining portion and is in a laterally inclined state with respect to the bottom surface 5301, and the PTP tablet sheet 900 is in the main body upper portion 530 of the tablet cassette 500. There may be a so-called tablet sheet lateral bridge that cannot be stored in place. The horizontal bridge makes it difficult for an extruding member (not shown) to be applied to the rear end of the lowermost PTP tablet sheet 900, which may impede the dispensing of the PTP tablet sheet 900 from the tablet cassette 500.

  FIG. 14 is a perspective view showing a state where the upper part of the main body of another tablet cassette is pulled out rearward, and FIG. 15 is a perspective view showing a state where the upper part of the main body of another tablet cassette is housed in the cassette base.

  Therefore, for example, as shown in FIG. 15, when the cassette base 510 accommodates the main body upper portion 530, the PTP tablet sheet 900 mounted on the main body upper portion 530 is parallel to the bottom surface 5301 and both left and right side surfaces 5311, The left and right side walls 516a and 517a for guiding the PTP tablet sheet 900 are preferably formed so as to have a posture (corresponding to a predetermined posture) that fits between 5312. The left and right side walls 516a and 517a have, for example, a substantially rectangular shape, and completely cover the notched portions of the left and right side walls 5311 and 5312 of the main body upper part 530 from the left and right sides in a state where the main body upper part 530 is completely accommodated. Is.

  As shown in FIG. 14, when the main body upper portion 530 is slid in the front-rear direction of the tablet cassette 500 and pulled backward, the PTP tablet sheet 900 is placed on the upper ends P, Q of the remaining portions of the left and right side walls 5311, 5312. As shown in FIG. 15, when the main body upper portion 530 is slid and accommodated in the front cassette base 510, the horizontal inclination is caused by the left and right side walls 516a and 517a of the cassette base 510, The PTP tablet sheet 900 in the state is guided to the above posture.

  In this way, the horizontal bridge of the PTP tablet sheet 900 can be easily and reliably eliminated over the entire main body upper part 530.

  In the above embodiment, the PTP tablet cassettes 500, 500,... Are arranged on the shelf plate 602 of the cassette shelf 600 in the width direction of the PTP tablet cassettes 500, 500,. However, the shelf plate is not limited to a stationary flat plate shape, and may be, for example, a cylindrical shape rotating around a predetermined axis. In that case, it is sufficient to move the chucking unit 400 relative to each PTP tablet cassette 500, 500,... Mounted on the rotating shelf.
