Description

  The present invention relates to a drug stock structure of a dispensing device, and is particularly suitable for a drug stock structure of a dispensing device that automatically dispenses a packaged tablet called a PTP (press-through package) tablet sheet into a tablet cassette.

  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.

  Accordingly, 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. To be supplied.

  In the conventional dispensing device, a plurality of PTP tablet sheets are stacked in the vertical direction and stored in the tablet cassette, and the lowest PTP tablet sheet is dispensed one by one.

  FIG. 7 is a diagram showing a general configuration of the PTP tablet sheet 900, in which (a) is a plan view and (b) is a side view. FIG. 8 is an explanatory view showing an extruding operation of the PTP tablet sheet 900 in the conventional dispensing device. FIG. 8A shows a case where the PTP tablet sheets 901, 902,. ) Shows the case of soft PTP tablet sheets 901, 902, and (c) shows the case of compressed PTP tablet sheets 901, 902, respectively.

  As shown in FIGS. 7 (a) and 7 (b), the surface 910 of the PTP tablet sheet 900 is formed with pockets 920 each containing a tablet, and the pocket 920 faces upward in the tablet cassette. Thus, each PTP tablet sheet 900 is accommodated, and usually, one end side in the longitudinal direction is provided with an ear portion 930 for chucking with a chucking device. It was.

  The PTP tablet sheet 900 is stored in a box and sold by a manufacturer or the like, and is taken out from the box and filled into a tablet cassette. The box stores the PTP tablet sheet 900 with the pocket forming surfaces facing each other. For this reason, in the conventional dispensing device, when the PTP tablet sheet 900 is transferred from the box to the tablet cassette, the work of aligning the orientation of the PTP tablet sheet 900 is required, which is troublesome.

  Moreover, in the conventional dispensing device, since all the PTP tablet sheets 900 are aligned so that the pockets 920 face upward, the number of sheets stored in the tablet cassette is small. For this reason, it is necessary to frequently fill the tablet cassette with the PTP tablet sheet 900, and when a prescription with a large number of sheets is applied, the dispensing operation is performed for filling the tablet cassette with the PTP tablet sheet 900. There was a problem that could be interrupted.

  Furthermore, in the conventional dispensing device, since the PTP tablet sheets 900 are dispensed one by one from the tablet cassette, the dispensing speed of the PTP tablet sheets 900 is slow. For this reason, when a prescription with a large number of sheets is applied, there is a problem that it takes time to pay out.

  Therefore, as shown in FIG. 8 (a), the present inventors set the PTP tablet sheets 900 (901, 902, 903, 904, 905, 906,...) So that their pocket forming surfaces face each other. Then, it is installed in the tablet cassette in a state where two sheets are stacked in the vertical direction, and a pair of PTP tablet sheets 901 and 902 at the bottom of the tablet cassette is simultaneously discharged by the extrusion member 5515. It was decided. The partition piece 5313a is installed so that the second set (set) of PTP tablet sheets 903 and 904 does not pop out during the payout. The standard of the installation is about 1.5 times the overlap height H of the PTP tablet sheets 901 and 902.

  However, as shown in FIG. 8 (b), the PTP tablet sheets 901, 902,... In the tablet cassette have a so-called soft (non-compressed) PTP tablet sheet 901,. When a large amount is set, the weight of the other PTP tablet sheet 902 is applied to the lowermost PTP tablet sheet 901, as shown in FIG. Since the interval with the PTP tablet sheet 902 is reduced (compressed), the overlapping height H in FIG. 8A changes.

  When the overlapping height H in the compressed state is less than half that in the non-compressed state, it is difficult to set the partition piece 5313a. That is, if the partition piece 5313a is set on the basis of the soft PTP tablet sheets 901, 902,..., Two sets of PTP tablet sheets are simultaneously dispensed during compression. On the other hand, if the partition piece 5313a is set on the basis of compression, the soft PTP tablet sheets 901, 902,... Cannot pass through the partition piece 5313a. In this case, there is a method in which a weight is placed on the PTP tablet sheets 901, 902,..., And the compressed state is always applied. However, when such a method is applied, the PTP tablet sheets 901, 902,. Each time it is replenished, the weight must be taken in and out, which is troublesome.

  The present invention has been made in view of such circumstances, and can always pay out accurately regardless of the state (non-compressed state, compressed state) of the medicine sheet stored in the medicine cassette, and the partition. An object of the present invention is to provide a drug stock structure of a dispensing device that makes it easy to determine a set value of a piece.

The present invention stores a medicine sheet in which pockets containing medicines are arranged on one side so as to overlap in a setting direction from a reference surface of the medicine cassette, and the medicine sheet accommodated in the medicine cassette is stored in the medicine cassette. The medicine stock structure of the dispensing device configured to be taken out to the outside in order from the one closest to the reference surface of the medicine, the one side of the medicine sheet facing each other in the medicine cassette in a state where the pockets do not overlap each other by arranging, advance and stored as a set of two by two sheets of drug sheet, the drug sheets housed in the set of one by the two, as taken to the medicine cassette outside the set units of the medicament partially busy TECHNICAL an opening formed in the cassette by the partition pieces, the partition piece, the reference in the contactable site in the medicament sheet the partition sections It is characterized in that the side closer is inclined outwardly, yet was so as to compress the medicament between sheets sent by two sheets. The drug includes tablets, capsules and the like.

According to the present invention, in the medicine cassette, the medicine sheets are stored as a set of two sheets by disposing one side of the medicine sheet facing each other so that the pockets do not overlap each other. the drug sheets housed in the set of one by the two, as taken to the medicine cassette outside the set units of partially busy TECHNICAL an opening formed in the drug cassette by the partition pieces, the partition Since the piece is inclined outwardly on the side close to the reference surface in the portion of the partitioning piece that can contact the drug sheet, and the drug sheets sent two by two are compressed , The medicine sheets set in the medicine cassette and fed two by two are compressed so as to have a substantially constant interval.

  Thereby, the setting value of a partition piece becomes easy to determine. For example, if the height of the partition piece is set to the height of the compressed medicine sheet × 2−several mm, the second set of medicine sheets abuts against the partition piece, thereby reliably preventing simultaneous dispensing. Will be able to. As a result, a large amount of drug sheet can be stably supplied.

  By the way, when the inclination angle on the side close to the reference surface in the part of the partitioning piece that can come into contact with the medicine sheet is small, the resistance increases in contact with the medicine sheet, and the medicine sheet moves toward the reference surface. Since it stops there without being guided, it becomes a payout failure. On the other hand, when the inclination angle on the side close to the reference surface in the part of the partitioning piece that can contact the medicine sheet is large, the maximum length of the medicine sheet that can be accommodated in the medicine cassette is shortened. Therefore, as in the second aspect of the present invention, the inclination angle of the partitioning piece on the side close to the reference surface in the portion that can contact the drug sheet is approximately 45 degrees with respect to the reference surface. preferable.

  According to the second aspect of the present invention, an inclination angle of the partitioning piece on the side close to the reference surface in the portion that can contact the drug sheet is approximately 45 degrees with respect to the reference surface. As in the case where the inclination angle on the side close to the reference surface in the part of the piece that can be in contact with the medicine sheet is small, there is no occurrence of defective dispensing, and it is possible to contact the medicine sheet of the partition piece The maximum length of the medicine sheet that can be accommodated in the medicine cassette is not shortened as in the case where the inclination angle on the side close to the reference surface is large.

  In addition, the pocket height varies depending on the type of the drug sheet and the interval between the drug sheets is not constant. Therefore, if the partition piece is fixed at a certain position, there is a possibility that a payout failure may occur. Therefore, it is preferable to provide a position adjusting unit that adjusts the position with respect to the reference plane, as in the third aspect of the invention.

  According to the invention of claim 3, since the partition piece includes a position adjusting unit that adjusts the position with respect to the reference surface, when the interval between the drug sheets is not constant depending on the type of the drug sheet or the like. However, by adjusting the position of the partition piece, there is no occurrence of a payout failure.

  Further, depending on the shape of the corner portion of the partitioning piece that can come into contact with the drug sheet, the drug sheet may be caught on the corner portion, resulting in poor dispensing and possible damage to the drug sheet. Therefore, as in the invention described in claim 4, it is preferable that the partition piece is provided with a radius at a corner portion of the part that can come into contact with the drug sheet.

  According to the invention of claim 4, since the corner pieces are provided at the corners of the part that can come into contact with the medicine sheet, the medicine sheet may be caught at the corners, resulting in poor dispensing. At the same time, there is no risk of damaging the drug sheet.

  In addition, depending on the material of the partition piece, it may be difficult to make a round at the corner of the part that can contact the drug sheet. Therefore, as in the invention described in claim 5, it is preferable that the partition piece includes a resin block capable of coming into contact with the drug sheet.

  According to invention of Claim 5, since the said partition piece was equipped with the resin block which can contact | abut to the said chemical | medical agent sheet, it is easy to provide a round at the corner | angular part of the resin block which can contact | abut to a chemical | medical agent sheet. it can.

As in the invention of claim 6, wherein the agent sheet is capable of accommodating stacked vertically on the bottom inside the medicine cassette, the partition piece, from top to bottom an opening definitive in the drug cassette It is preferable that the lower side of the part of the partitioning piece that can be attached to the medicine sheet and in contact with the drug sheet is inclined outward.

According to the invention described in claim 6, wherein the agent sheet is capable of accommodating stacked vertically on the bottom inside the medicine cassette, the partition piece, from top to bottom an opening definitive in the drug cassette Since the lower side of the part of the partitioning piece that can be in contact with the drug sheet is inclined outward, the drug sheets that are sent two by two are spaced at regular intervals. Is compressed.

According to the present invention, in the medicine cassette, the medicine sheets are stored as a set of two sheets by disposing one side of the medicine sheet facing each other so that the pockets do not overlap each other. the drug sheets housed in the set of one by the two, as taken to the medicine cassette outside the set units of partially busy TECHNICAL an opening formed in the drug cassette by the partition pieces, the partition Since the piece is inclined outwardly on the side close to the reference surface in the portion of the partitioning piece that can contact the drug sheet, and the drug sheets sent two by two are compressed , The medicine sheets set in the medicine cassette and fed two by two are compressed so as to have a substantially constant interval.

  Thereby, the setting value of a partition piece becomes easy to determine. For example, if the height of the partition piece is set to the height of the compressed medicine sheet × 2−several mm, the second set of medicine sheets abuts against the partition piece, thereby reliably preventing simultaneous dispensing. Will be able to. As a result, a large amount of drug sheet can be stably supplied.

  FIG. 1 is an exploded perspective view showing main components of a dispensing device 1 according to an embodiment of the present invention.

  As shown in FIG. 1, the dispensing device 1 includes two Y carriages 200 and 200 provided on the left and right sides of the box-shaped device main body 100, and X carriages supported by the Y carriages 200 and 200, respectively. 300, 300, take-out units 400, 400 supported by these X carriages 300, 300, and two on the front left and right sides of the apparatus main body 100, and a plurality of tablet cassettes (corresponding to drug cassettes). 500, 500,... Are arranged below the left and right cassette shelves 600, 600 across the left and right ends of both cassette shelves 600, 600. And a transport conveyor unit 800 of the table.

  Hereinafter, representative components of a plurality of components will be described. The Y carriage 200 includes a servo motor 210, a ball screw 220 in the vertical axis direction (Y direction in FIG. 1) driven by the servo motor 210, vertical guides 230 and 230 respectively disposed on the left and right of the ball screw 220, The X carriage 300 includes a carriage main body 310 that moves up and down together with the nut 240 by the rotation of the ball screw 220 while being guided by the vertical guides 230 and 230, and the carriage main body. On 310, a servo motor 410, a ball screw 415 in the horizontal axis direction (X direction in FIG. 1) driven by the servo motor 410, and a nut (not shown) are provided.

  2 is a perspective view showing the configuration of the tablet cassette 500 in the present embodiment, FIG. 3 is a front view of FIG. 2, and FIG. 4 is a cross-sectional view taken along line AA in FIG. In each figure, unless otherwise specified, the front side facing the take-out unit 400 of the tablet cassette 500 is referred to as the front side, the back side is referred to as the rear side, and the left side and the right side are viewed from the front side to the rear side. Shows things.

  The tablet cassette 500 in this embodiment is formed to be slightly wider than the various PTP tablet sheets (corresponding to drug sheets) 900 to be loaded. Accordingly, a plurality of tablet cassettes 500 having different width dimensions are prepared according to the widths of various PTP tablet sheets 900. As shown in FIGS. 2 to 4, the specific configuration thereof is a long cassette base 510 having a concave cross section, and a cassette body 520 that is detachably fitted from the longitudinal direction of the cassette base 510. It is made up of.

  The cassette base 510 is provided with a mounting portion (not shown) for attaching the cassette shelf 600 to the shelf plate 602, so that even the tablet cassette 500 having a different width dimension is arranged at an arbitrary position in the width direction. Be able to.

  The cassette body 520 is mounted on the cassette base 510 at the upper portion 530 of the main body 530 on which a plurality of PTP tablet sheets 900 (901, 902,. The main body lower portion 540 is formed.

  The main body lower part 540 is arranged in an assembled state with the cassette base 510 of the cassette main body 520 and is embedded in the cassette base 510, but when viewed as a single unit, the main body lower part 540 has a long shape with a concave cross section. An extrusion mechanism 550 for taking out as a set the PTP tablet sheets 901 and 902 loaded on the bottom of the main body upper part 530 and immediately above it is provided in the housing.

  The main body upper part 530 has an L-shape in a side view and is projected from the middle part to the front part so as to protrude above the cassette base 510 in the assembled state of the cassette body 520 to the cassette base 510. The side walls 5311 and 5312 are bent inward from each other at the front end to be opposed to each other with a predetermined gap, 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.

  By the way, the PTP tablet sheets 901, 902,... Stacked in the main body upper part 530 of the tablet cassette 500 are the PTP tablet sheets 901, 902 loaded first, and the PTP tablet sheet 903 loaded next. , 904, the lower side of the set, so that the set of PTP tablet sheets 901, 902 loaded first is taken out before the set of PTP tablet sheets 903, 904 loaded next. First-in, first-out in units.

  For this reason, each set of PTP tablet sheets 901 and 902 at the bottom of the main body upper part 530 of the tablet cassette 500 is taken out of the main body upper part 530, but the PTP tablet sheets 901 and 902 are set. And a set of PTP tablet sheets 901 and 902 on the bottom and a set of PTP tablet sheets 903 and 904 on the upper side are simultaneously removed from the upper portion 530 of the main body by friction between the PTP tablet sheets 903 and 904 So-called multiple removal may occur.

  As shown in FIG. 8 (b), PTP tablet sheets 901, 902,..., Which are so-called soft (in a non-compressed state) PTP tablet sheets 901, 902,. When a large amount is set in 500, as shown in FIG. 8C, the weight of the other PTP tablet sheets 902,... And the PTP tablet sheet 902 above it are narrowed (compressed), the overlapping height H between the PTP tablet sheets 901 and 902 changes, resulting in the above-described multiple removal. Such inconvenience is as described above.

  Therefore, in the present embodiment, in order to prevent multiple removal of the PTP tablet sheets 901, 902,... Stored in the tablet cassette 500 as a set of two sheets, the bottom plate of the upper part 530 of the main body of the tablet cassette 500 is used. (It corresponds to a bottom surface and a reference surface.) PTP tablet sheets 904 at a higher position than the even-numbered set position of the fourth or more sheets counting from the PTP tablet sheet 901 at the bottom on 5301. A partition piece 5313 that prohibits the tablet cassette 500 from being taken out is provided.

  As shown in FIGS. 2 to 4, the partition piece 5313 has an oblong shape when viewed from the front. However, a vertical hole 5316 is formed from the upper part to the middle part, and the lower part is slightly folded backward. It is a variant that protrudes slightly diagonally forward. When this inclination angle is small, the resistance increases in contact between the partition piece 5313 and the second PTP tablet sheet 902, and the PTP tablet sheet 902 stops there without being guided downward. Become. On the other hand, when the inclination angle of the partition piece 5313 is large, the protruding amount of the partition piece 5313 increases. The protrusion amount is limited to a certain value or less in order to eliminate interference with the take-out unit 400. As the protrusion amount increases, the partition piece 5313 enters the inside of the front wall 531, and as a result, the PTP accommodated in the tablet cassette 500. The maximum length of the tablet sheets 901, 902,. Therefore, the inclination angle of the lowermost end of the partition piece 5313 is set to about 45 degrees with respect to the bottom plate 5301. However, this inclination angle is not necessarily limited to about 45 degrees. In some cases, any other inclination angle can be taken as long as it is in a range larger than 0 degrees and smaller than 90 degrees.

  Here, depending on the type of the PTP tablet sheets 901, 902,..., The sheet interval at the time of compression varies greatly due to the difference in the pocket height and the like. It is not preferable. Therefore, a convex member 5314 is detachably attached to the left side of the front wall 531 of the tablet cassette 500 with a screw 5315. The partition piece 5313 is attached to the convex member 5314 by inserting two screws 5317 and 5317 through the elongated hole 5316.

  Therefore, the partition piece 5313 can set the height position of the partition piece 5313 by loosening the two screws 5317 and 5317 and sliding it up and down along the convex member 5314 (position adjustment). Part function). Here, the partition piece 5313 is set at a height position at which the fourth PTP tablet sheet 904 can come into contact with the PTP tablet sheet 900 at the bottom on the bottom plate 5301 of the upper body 530 of the tablet cassette 500. To do. For example, the height of the partition piece 5313 may be set to the height between the compressed PTP tablet sheets 901 and 902 × 2 to several mm.

  In this way, the partition piece 5313 partially blocks the opening 5318 formed below the front wall 531 of the tablet cassette 500 from the top to the bottom, and the lower end of the partition piece 5313 is outwardly approximately 45 degrees. By determining only the inclination, the set value of the partition piece 5313 can be easily determined. In addition, with a simple configuration, multiple take-out can be reliably prevented, and a large amount of PTP tablet sheets 901, 902, ... can be taken out stably. Further, the number of PTP tablet sheets 901, 902,... Taken out from the tablet cassette 500 can be adjusted according to the prescription, which is convenient.

  It is not necessary to adjust the position of the partition piece 5313 in the left-right direction. The PTP tablet sheet 900 at the even-numbered setting position from the bottom with which the partition piece 5313 comes into contact has the pocket 920 facing downward, so that the partition piece 5313 purposely makes contact with the pocket 920 while avoiding it. It is not necessary. However, when it comes into contact with the second PTP tablet sheet 902, the pocket 920 obstructs the removal of the lowermost PTP tablet sheet 901. This is the reason for setting the even-numbered setting position of the fourth or more sheets.

  As shown in FIG. 1, the take-out unit 400 includes Z carriages 411 and 411 (the front side is not shown in FIG. 1) extending forward (Z direction in FIG. 1) from the carriage body 310, and Z. Dispensing plates 430 and 430 disposed between the carriages 411 and 411 so as to be movable back and forth and openable and closable, and pushers 440 and 440 disposed on the side of the dispensing plates 430 and 430 facing the tablet cassette 500 are provided.

  The advancing and retreating operations of the payout plates 430 and 430 are performed by rotationally driving a ball screw (not shown) by the servo motor 420, and the opening and closing operation is performed by mutually rotating the rotation shafts through the gear train by a stepping motor (not shown). It is configured to perform by rotationally driving in the direction. A primary bucket 450 is provided below the payout plates 430 and 430, and a secondary bucket 480 with a shutter 470 is further provided below the primary bucket 450.

  Hereinafter, the dispensing operation of the PTP tablet sheet 900 (901, 902, 903, 904,...) From the tablet cassette 500 by the dispensing device 1 will be schematically described. FIG. 5 is a diagram schematically showing PTP tablet sheets 901, 902,... Stacked in the tablet cassette 500. FIG. 5A shows a partition piece 5313 in which the lowermost PTP tablet sheets 901, 902 are set. FIG. 6B is a side sectional view showing a state when passing through the sheet, and FIG. 5B is a side sectional view showing a state when the PTP tablet sheets 901, 902,.

  Now, as shown in FIG. 5 (a), two PTP tablet sheets 901, 902,... Are set in the tablet cassette 500 so that the pockets 920, 920,. (It is in a state where it is taken out from a commercially available box, and between the upper and lower PTP tablet sheets 901 and 902, the ears 930 and 930 are reversed in the front-rear direction and in the opposite directions.) In addition, it is assumed that the pushing member 5515 comes into contact with the rear end of the PTP tablet sheet 901 at the lowest position.

  At this time, it is assumed that the take-out unit 400 is in a position facing the front side of the tablet cassette 500, and the payout plates 430 and 430 are in a horizontal posture together with the pushers 440 and 440.

  First, by driving the servo motor 420 of the take-out unit 400, the dispensing plates 430 and 430 are moved toward the front side of the tablet cassette 500. Eventually, one of the pushers 440, 440 of the dispensing plates 430, 430 directly presses a member (not shown) of the tablet cassette 500. Then, by the action of the pushing mechanism 550, the pushing member 5515 in FIG. 5A moves forward, and the pushing member 5515 in FIG.

  At this time, the pushing member 5515 pushes the PTP tablet sheets 901 and 902 forward from the main body upper part 530 of the tablet cassette 500. Then, the upper PTP tablet sheet 902 comes into contact with the oblique portion formed at the lower part of the partition piece 5313 and guides the tip thereof downward, so that the interval with the lower PTP tablet sheet 901 is narrowed, and the overlapping of the compressed state The combined height is H. The set of PTP tablet sheets 901 and 902 in this compressed state can pass through the partition piece 5313. On the other hand, for the set of PTP tablet sheets 903 and 904, the upper PTP tablet sheet 904 comes into contact with an oblique portion formed at the lower part of the partition piece 5313, and the set of PTP tablet sheets 903 and 904 passes through the partition piece 5313. To prevent it.

  Then, the two PTP tablet sheets 901 and 902 that have passed through the partition piece 5313 drop by gravity onto the payout plates 430 and 430 of the take-out unit 400. In this manner, the PTP tablet sheets 901 and 902 can be dispensed by the take-out unit 400 and taken out from the tablet cassette 500.

  When the set of PTP tablet sheets 901 and 902 is taken out, the discharge plates 430 and 430 of the take-out unit 400 receive the PTP tablet sheets 901 and 902 together with the pushers 440 and 440 and return to the original positions. The pushing member 5515 also returns to the original last part. At the time of this return, the pushing member 5515 is pulled back under the next set of PTP tablet sheets 903 and 904 and enters a standby state.

  Next, by driving a stepping motor (not shown) to rotate the dispensing plates 430 and 430 in opposite directions around the rotation axis and opening them downward, the PTP tablet sheets 901 and 902 taken out from the tablet cassette 500 are removed. It can be dropped 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.

  Then, a bottom shutter (not shown) of the primary bucket 450 is opened, and the PTP tablet sheets 901 and 902 are dropped into the secondary bucket 480. Next, the bottom shutter 470 of the secondary bucket 480 is opened, and the PTP tablet sheets 901 and 902 are dropped onto the transport conveyor unit 800.

  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 sheets 901 and 902 dropped from the secondary bucket 480 via the shutter 470 fall into one of the tablet takeout buckets 802 and 802.

  The PTP tablet sheets 901 and 902 that have fallen into one of the tablet take-out buckets 802 and 802 are further moved to a predetermined site while being stored in the tablet take-out buckets 802 and 802, and are discharged from there.

  As described above, according to the present embodiment, PTP tablet sheets 901, 902,... Are placed in the tablet cassette 500 so as to face each other with their pockets not overlapping each other. The tablet sheets 901, 902,... Are stored in sets of two, and the PTP tablet sheets 901, 902,. The opening 5318 formed in the front wall 531 of the tablet cassette 500 is partially blocked by the partition piece 5313 and the lower side of the partition piece 5313 is inclined outward so as to be taken out of the tablet cassette 500 in multiple units.

An outwardly inclined surface 5313h is formed below the upright surface 5313g with which the PTP tablet sheets 901, 902,... Of the resin block 5313c can come into contact. Similarly to the partition piece 5313, it is preferably set to be approximately 45 with respect to the bottom plate 5301.

  In this partition piece 5313b, in addition to the effects of the above embodiment, the corners 5313i, 5313j,... Of the resin block 5313c that can contact the PTP tablet sheets 901, 902,. Since the PTP tablet sheets 901, 902,... Are caught on the corners 5313i, 5313j,..., And the payout is not defective, the PTP tablet sheets 901, 902,.・ It may have a special effect that there is no risk of hurting.

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

  Further, when two or more cassette shelves are arranged, a part of the PTP tablet sheets may be taken out from the tablet cassette one by one like a conventional dispensing device. In that case, you may make it perform what is called a fraction process which cuts a PTP tablet sheet | seat into the predetermined number of tablets with a cutting unit, and dispenses it.

  Moreover, in the said embodiment, although the one taking-out unit 400 is moved to the several tablet cassette 500, and PTP tablet sheet is paid out from the said tablet cassette 500, each tablet cassette and taking-out unit are made into. A one-to-one correspondence may be provided. In that case, the configuration of the take-out unit can be simplified.

  In the above embodiment, each PTP tablet sheet 901, 902,... Is dispensed from the tablet cassette 500 in units of two sets, but may be dispensed in multiples of this set. This makes it possible to dispense the optimal number of PTP tablet sheets 901, 902,... From the tablet cassette 500 according to the content of the prescription, which is convenient.

  .. Instead of extruding the PTP tablet sheets 901, 902... From the tablet cassette 500 in set units or multiple set units thereof, the PTP tablet sheets 901, 902. It is good also as employ | adopting the system pulled out by the set unit of a multiple.

  Moreover, in the said embodiment, although the PTP tablet sheet | seat 901,902, ... of a horizontal orientation was made into the set of 2 sheets each and it accumulated in the up-down direction in the tablet cassette 500, this is illustrated. The scope of application of the present invention is not limited to this, and it may be a tablet cassette in which PTP tablet sheets 901, 902,... . In this case, since the spring force works instead of gravity, the same result as described above is obtained.

  In the above-described embodiment, the PTP tablet sheets 901, 902,... Are so-called ear sheets each having an ear portion 930. However, a part or all of the PTP tablet sheets 901, 902,. There may be no sheet. Even in that case, since the PTP tablet sheets 901, 902,...
