Japanese Utility Model Publication No. 5-71101

  As described above, the bottom plate 106 is configured to be supported from below by the moving plate 107 and the fixed plate 108. However, the positional relationship between the under tablet cassette 104, the moving plate 107, and the fixed plate 108 varies depending on the dimensional accuracy of the individual components constituting the medicine supply device and the assembly accuracy of each component. As shown, the bottom plate 106 may hang downward even when supported from below, and a gap Z may remain between the supply rod 105 and the bottom plate 106.

  Here, some tablets have a small thickness (for example, about 1 mm in thickness). When supplying this thin tablet, if the gap Z remains between the supply basket 105 and the bottom plate 106, the lower opening should be covered by the bottom plate 106, as shown in FIG. From the supply bowl 105 passes through the gap Z and falls. Because this drop is not intended, there may be inconveniences that tablets remain inside the medicine packaging machine, etc., or that different amounts (more or less than the prescription) of tablets are packaged. There is. However, it is not preferable to increase the dimensional accuracy and assembly accuracy of the component in order to eliminate the gap Z in order to suppress this inconvenience, because this leads to an increase in manufacturing cost.

  Then, this invention makes it a subject to provide the chemical | medical agent supply apparatus which can suppress unintentional fall of a tablet etc., suppressing the raise of manufacturing cost.

  The present invention is a drug supply device for subdividing and supplying a tablet and a drug in a dosage form similar to a tablet, comprising a tablet supply unit for temporarily storing tablets and the like, wherein the tablet supply unit is a tablet A supply unit body, a bottom plate, and a bottom plate support member, wherein the tablet supply unit body includes a plurality of supply bowls, and the supply bowl has an upper opening and a lower opening; There is a tablet storage space, and a plurality of the bottom plates are provided in the tablet supply unit main body corresponding to each of the plurality of supply rods, one end is supported by the tablet supply unit main body, and the one end is centered The lower opening is opened and closed by rotating the other end in the vertical direction, and the bottom plate support member is provided so as to be able to regulate the rotation of the bottom plate by supporting the bottom plate. The tablet supply unit body and the bottom plate support member are relatively moved in the horizontal direction. The bottom plate is rotated between the open state and the open state by the relative movement, and the supply rod has an inner peripheral portion and an outer peripheral portion with the peripheral edge of the lower opening. The lower surface of the inner peripheral edge is located above the lower surface of the outer peripheral edge, and the bottom plate can contact the lower surface of the inner peripheral edge. is there.

  Further, in the present invention, in a state where the bottom plate closes the lower opening, at least a part of the upper surface of the bottom plate is located above, the lower surface of the peripheral edge of the lower opening is located below, The bottom plate support member is provided at a position spaced downward with respect to the lower surface of the bottom plate, and a portion of the upper surface of the bottom plate that is positioned at an uppermost position in a state where the bottom plate closes the lower opening and the lower plate The distance from the lower surface of the peripheral edge in the opening may be equal to or greater than the distance between the lower surface of the bottom plate and the upper surface of the bottom plate support member in the same state.

  Moreover, in this invention, the said baseplate shall be equipped with the part located in the said tablet accommodation space in the state which closed the said lower opening part.

  In the present invention, the bottom plate includes a base portion and a protruding portion protruding upward from the base portion, and the base portion is located outside the tablet housing space in a state where the lower opening is closed, The protrusion can be positioned in the tablet storage space in the same state.

  In the present invention, the protrusion may be provided from one end to the other end in the horizontal direction.

  Further, in the present invention, the projecting portion may be configured such that the upper end portion of the projecting portion is inclined with respect to the base portion by projecting the portion closer to the other end portion than the portion closer to the one end portion. .

  In the present invention, in the state where the bottom plate is supported by the bottom plate support member and is prevented from being opened, it is difficult to form a gap through which tablets or the like pass unexpectedly between the supply bowl and the bottom plate. For this reason, it is possible to suppress an unintended drop of a tablet or the like while suppressing an increase in manufacturing cost.

  Next, the present invention will be described by taking up one embodiment. In addition, the dosage form of the chemical | medical agent used as the supply object of the chemical | medical agent supply apparatus of this invention is not limited only to a tablet. For example, capsules and the like, which can be hand-picked by the operator by hand or the like on the top tablet cassette, can be used as the supply object. In the following, for convenience, the supply object will be described as a tablet.

  For example, as shown in FIG. 1, the drug supply device of the present embodiment is built in a drug packaging machine capable of packaging powders and tablets. This medicine supply device is used to divide and supply tablets, and, as shown in FIG. 2, a top tablet cassette 1, an under tablet cassette 2 as a tablet supply portion located below, and an under tablet cassette. A support plate 3 serving as a bottom plate support member is provided below the tablet cassette 2.

  The top tablet cassette 1 includes a main body 11 in which a plurality of distribution baskets 12... 12 arranged in a matrix form in the left and right and depth directions. The distribution basket 12 has an upper opening and a lower opening that are substantially square in a plan view and a bottom view. The top tablet cassette 1 does not move with respect to the medicine packaging machine when tablets are supplied. And this top tablet cassette 1 is provided with the shutter 13 which opens and closes the lower opening part of distribution basket 12 ... 12. As shown in FIG. 2, the shutter 13 includes an upper shutter 131 and a lower shutter 132, and can be opened by sliding the shutters 131 and 132 in the horizontal direction. When the shutter 13 is closed, as shown in FIG. 5A, the tablets M can be temporarily held in the distribution baskets 12. When the shutter 13 is opened, as shown in FIG. 5 (B), the tablets M held in the distribution baskets 12 ... 12 can be dropped into the under tablet cassette 2.

  The under tablet cassette 2 includes a main body 21 in which a plurality of supply rods 22 ... 22 arranged in a matrix corresponding to the top tablet cassette 1 is formed. Similarly to the distribution basket 12, the supply basket 22 has an upper opening and a lower opening that are substantially square in plan view and bottom view, and a tablet storage space 22a is formed between the openings. That is, the tablet storage space 22a is a region above the virtual surface defined by the lower surface 22b (see FIG. 7A) at the peripheral edge of the lower opening in the space in the supply basket 22. As shown in FIGS. 5 and 6, the under tablet cassette 2 is configured to be horizontally movable in the longitudinal direction (the left-right direction in the drawing) with respect to the top tablet cassette 1. However, the under tablet cassette 2 may be configured to move relative to the support plate 3, and a configuration in which the under tablet cassette 2 is fixed to the top tablet cassette 1 may be employed.

  As shown in FIG. 3, the under tablet cassette 2 includes a plurality of bottom plates 23 that open and close the lower openings of the supply baskets 22... 22 (note that the closed state of the bottom plate 23 is virtually shown in FIG. 3). However, when there is no support from below by the support plate 3, the bottom plate 23 is actually open). The bottom plate 23 is provided so as to be closed by covering the lower openings of the supply rods 22. The bottom plate 23 is pivotally supported by the main body 21 and can be rotated in the vertical direction, and closes the lower opening when the bottom plate 23 is at the upper end of the rotation range. The bottom plate 23 is pivotally supported at one end 23X in the horizontal direction (the left end in FIG. 3 (the right end is referred to as the “other end 23Y”)). As a result, the bottom plate 23 is rotatable with respect to the main body 21 around the one end portion 23 </ b> X on the shaft support side. Since the bottom plate 23 is not urged by a spring or the like, the bottom plate 23 is opened by its own weight.

  As shown in FIGS. 5 and 6, the bottom plate 23 is supported from below by a support plate 3 positioned below the under tablet cassette 2, so that the vertical rotation is restricted and the opening is prevented. It becomes a state. In this state, the supply basket 22 and the bottom plate 23 are close to each other with a gap that prevents the tablet M from passing through. Then, by releasing the shutter 13 of the top tablet cassette 1, the tablets M dropped from the distribution baskets 12 ... 12 of the top tablet cassette 1 are temporarily stored in the tablet storage spaces 22a ... 22a in the supply baskets 22 ... 22. Can be accommodated.

  The bottom plate 23 has the shape shown in FIG. 4 and is integrally formed. The bottom plate 23 of the present embodiment is formed by pressing stainless steel, but can be formed by various materials (synthetic resin, etc.) and manufacturing methods. The bottom plate 23 includes a base 231, a shaft support 232, and a protrusion 233.

  The base 231 has a flat plate shape, and the upper surface can contact the lower surface 22b of the peripheral edge of the lower opening in the supply rod 22 (see FIG. 7A). The shaft support portion 232 is a tubular portion that is provided at one end portion 23 </ b> X of the bottom plate 23 and through which the shaft portion 24 (see FIG. 7) extending in the depth direction of the under tablet cassette 2 passes.

  The protruding portion 233 is a portion at least partially protruding upward from the base portion 231 in a state where the bottom plate 23 closes the lower open portion of the supply rod 22. That is, in the same state, at least a part of the upper surface of the bottom plate 23 is positioned above, and the lower surface 22b of the peripheral edge in the lower opening is positioned below. The projecting portion 233 has a substantially square shape in plan view (a little smaller) that substantially matches the shape of the lower opening of the supply rod 22, and is provided from one end 23 </ b> X to the other end 23 </ b> Y of the bottom plate 23. For this reason, it can suppress that a clearance gap produces between the bottom plates 23 in the whole supply rod 22. FIG.

  In the present embodiment, the upper surface 233a of the protrusion 233 is an inclined surface. Specifically, since the protruding amount on the other end 23Y side of the protruding portion 233 is formed larger than the protruding amount on the one end portion 23X side, the upper surface 233a of the protruding portion 233 is a piece with respect to the flat base portion 231. It is inclined with a gradient.

  Since the bottom plate 23 is provided with the protruding portion 233 as described above, the base portion 231 comes into contact with the lower surface 22b of the peripheral edge of the lower opening portion to close the lower opening portion, as virtually shown in FIG. If it becomes the state which became, the upper surface 233a in the protrusion part 233 will be located above the lower surface 22b of the periphery in the lower opening part of the supply rod 22 by the height H1 shown in figure. In other words, the protruding portion 233 enters the tablet accommodating space 22a for the height H1.

  Since the protruding portion 233 enters the tablet accommodating space 22a in this way, even if the other end portion 23Y on the rotating end side is slightly hung depending on the positional relationship between the bottom plate 23 and the support plate 3 (FIG. 7). (See (C)), until the height of the sag reaches the height H1, a part of the protrusion 233 can be kept in the tablet accommodating space 22a. It is difficult to create a gap between the tablet M and the tablet M.

  In particular, in the other end portion 23Y that is the rotation end side of the bottom plate 23, the distance from the one end portion 23X that is the pivot support side is the largest, and therefore there is a gap between the supply rod 22 and the bottom plate 23. Has the largest gap due to the sagging. For this reason, in the bottom plate 23, a protrusion 233 is provided particularly near the other end 23Y, or a protrusion 233 having a larger protrusion than other positions is provided near the other end 23Y. It is effective to prevent the tablet M from passing through.

  Moreover, since the upper surface 233a of the protrusion part 233 is an inclined surface, the protrusion amount from the base 231 of the part near the one end 23X in the protrusion part 233 is smaller than the other part. For this reason, compared with the thing whose protrusion amount of the protrusion part 233 is the same on the whole surface, with respect to rotation of the baseplate 23, it is hard to produce with respect to the periphery of the lower opening part of the supply rod 22, and the baseplate 23 rotates smoothly. Furthermore, as shown in FIG. 7 (B), when the bottom plate 23 is in an open state, it is possible to suppress the tablet M from being caught on the protrusion 233 and remaining.

  In addition, the vertical positional relationship between the bottom plate 23 and the support plate 3 for the protrusion 233 to enter the tablet accommodating space 22a as described above is that the bottom plate 23 of the upper surface 233a of the protrusion 233 is the distribution basket 12. The distance in the vertical direction between the uppermost portion in the state where the lower opening portion is closed and the lower surface 22b of the peripheral edge in the lower opening portion is the vertical distance between the lower surface of the bottom plate 23 and the upper surface of the support plate 3 The positional relationship is greater than or equal to the distance in the direction.

  Next, the support plate 3 includes a moving plate 31 and a fixed plate 32 as shown in FIG. The fixed plate 32 is provided immovably. On the other hand, the moving plate 31 is movable in the longitudinal direction (horizontal direction). Thereby, the moving plate 31 is configured to be movable with respect to the under tablet cassette 2. Each of the plates 31 and 32 is provided at a position separated from the lower surface of the bottom plate 23. However, the support plate 3 may be configured to move relative to the under tablet cassette 2. Therefore, for example, a configuration in which each of the plates 31 and 32 can be moved may be employed. The “separated position” where the plates 31 and 32 are provided is a position where a distance is set so that the relative movement with respect to the under tablet cassette 2 is not hindered. However, as described above, the bottom plate 23 is not biased by a spring or the like and hangs down due to its own weight. Therefore, the other end portion 23Y of the bottom plate 23 and the upper surfaces of the plates 31 and 32 (specifically, the sliding plate 311). , 321) abuts. In other words, strictly speaking, even when the bottom plate 23 is supported from below by the support plate 3, the base 231 of the bottom plate 23 does not contact the lower surface 22 b at the opening edge of the supply rod 22, so the lower opening is closed. It will not be in the state.

  When the moving plate 31 moves in the horizontal direction, the bottom plate 23 is supported from below by the support plate 3 and is prevented from being released (see FIG. 7A), and the support is released (see FIG. 7A). 7 (see (B)). A tablet hopper 4 is provided below the movable plate 31 and the fixed plate 32 (see FIG. 6C), and the dropped tablet M is packaged via the tablet hopper 4 (illustrated). Not).

  A step is provided between the moving plate 31 and the fixed plate 32. Specifically, the upper surface of the fixed plate 32 is provided at a position lower than the upper surface of the moving plate 31. The reason is that, as described above, since the bottom plate 23 is pivotally supported on the main body 21 in the under tablet cassette 2 at the one end portion 23X, the other end portion 23Y hangs down due to the weight of the bottom plate 23 in a free state. . For this reason, when the under tablet cassette 2 moves rightward from the state shown in FIG. 5B to the state shown in FIG. 6A, the upper surface of the fixed plate 32 is higher than the upper surface of the moving plate 31. If it is in the position, the other end portion 23Y of the bottom plate 23 is caught on the left end portion of the fixed plate 32 in the figure, and the movement of the under tablet cassette 2 may be hindered.

  As shown in FIG. 2, a plurality of resin sliding plates 311 and 321 extending in the longitudinal direction are provided in parallel on the upper surfaces of the moving plate 31 and the fixed plate 32, respectively. The distance in the depth direction of the sliding plates 311 and 321 in each plate 31 and 32 is the same as the distance in the depth direction of the supply rods 22. When the under tablet cassette 2 moves (relatively) with respect to the support plate 3, the other end portion 23 </ b> Y of the bottom plate 23 contacts the sliding plates 311 and 321. For this reason, the friction which generate | occur | produces between the support plate 3 and the baseplate 23 can be reduced, and generation | occurrence | production of the metal powder by friction can also be suppressed.

  The moving plate 31 and the fixed plate 32 are provided with a gap in the longitudinal direction. In order to fill this gap, a support arm 312 is provided near the right end of the moving plate 31 in the figure. The support arm 312 is made of resin, and as shown in FIG. 5A, the base end 312 a is provided on the moving plate 31, and the tip 312 b is located in the gap between the moving plate 31 and the fixed plate 32. ing. The support arm 312 is urged by a spring, so that the tip 312b protrudes upward. For example, as shown in FIG. 6A, the support arm 312 supports the bottom plate 23 located in the gap between the moving plate 31 and the fixed plate 32 from below, so that the bottom plate 23 is in an open state. To prevent it.

  Next, the point of using the medicine supply device of this embodiment will be described. In addition, although the hand-working operation | work of the tablet M is based on an operator's manual work, operation other than that is made | formed automatically by the chemical | medical agent supply apparatus (chemical | medical agent packaging machine). FIG. 5A shows an initial position of each component of the medicine supply device. At this time, the shutter 13 of the top tablet cassette 1 is closed. An operator who operates the medicine packaging machine first hands a required amount of tablets M in accordance with the prescription to each of the dispensing baskets 12... 12 of the top tablet cassette 1.

  As shown in FIG. 5B, the under tablet cassette 2 is illustrated so that the distribution baskets 12 ... 12 of the top tablet cassette 1 and the supply baskets 22 ... 22 of the under tablet cassette 2 overlap each other vertically. Move to the left. When the shutter 13 of the top tablet cassette 1 is opened in this state, the tablet M falls from the top tablet cassette 1 to the under tablet cassette 2.

  Next, the under tablet cassette 2 moves to the right and enters the state shown in FIG. Thereafter, as shown in FIG. 6B, the under tablet cassette 2 and the moving plate 31 move horizontally to the left. Along with this, the bottom plate 23 (in the illustrated example, the leftmost bottom plate 23 of the supply rod 22), which has been unsupported from the lower side by the moving plate 31, rotates and enters an open state. Thereby, the tablet M falls from the supply basket 22 in the open state to the tablet hopper 4 provided below the support plate 3. And the tablet M which fell to the tablet hopper 4 is wrapped by the packaging paper by the packaging mechanism (not shown) provided under the chemical | medical agent supply apparatus.

  Here, the horizontal movement of the moving plate 31 to the left shown in FIG. 6 (B) is intermittent at a moving distance corresponding to the distance in the left-right direction in each of the supply baskets 22... Made. As shown in FIG. 2, the right end of the moving plate 31 and the left end of the fixed plate 32 are positioned on the right side toward the back side. That is, the end face shape of the opposing side of each plate 31 and 32 is a “staircase”. Thereby, with the intermittent movement of the moving plate 31, each of the supply baskets 22 is opened, and the tablets M are dropped.

  As described above, in the state where the opening of the bottom plate 23 is prevented, the protrusion 233 of the bottom plate 23 is positioned above the lower surface 22b of the peripheral edge in the lower opening of the supply rod 22 as shown in FIGS. To do. Therefore, the protruding height of the protruding portion 233 from the base portion 231 (the height H1 shown in FIG. 7A) is the vertical position due to the gap between the support plate 3 and the under tablet cassette 2. It can be an absorption allowance for absorbing the deviation. For this reason, within the range of the absorption allowance, as shown in FIG. 7C, the other end 23Y of the bottom plate 23 is allowed to hang down. Therefore, it is difficult to form a gap through which the tablet M unexpectedly passes between the supply basket 22 and the bottom plate 23 in a state where the opening of the protruding portion 233 is prevented.

  Since the upper surface of the fixed plate 32 is lower than the upper surface of the moving plate 31 as described above, the under tablet cassette 2 is fixed as shown in FIGS. 6 (A) and 6 (B). When located above the plate 32, the gap between the supply rod 22 and the bottom plate 23 is wider than when located above the moving plate 31. In this embodiment, even in such a case, it is effective that a gap is formed by the protruding portion 233 of the bottom plate 23 being positioned above the lower surface 22b of the peripheral edge in the lower opening of the supply rod 22. Can be suppressed.

  As described above, in the present embodiment, even when the thin tablet M is supplied, it is possible to suppress a gap that allows the tablet M to pass between the supply rod 22 and the bottom plate 23. Therefore, it is possible to reduce the possibility of inconvenience that the dropped tablet M remains inside the medicine packaging machine or the like, and a different amount (more or less than the prescription) of the tablet M is packaged. Can do. And, in order to prevent the gaps that allow the tablets M to pass through, it is not necessary to increase the dimensional accuracy of individual parts and the assembly accuracy of each part constituting the medicine supply device, so that the manufacturing cost increases. The effect can be fully demonstrated while suppressing.

  In addition, the shape of the baseplate 23 is not restricted to the shape of this embodiment, It can change variously. Hereinafter, other embodiments of the bottom plate 23 will be described. In FIG. 8A, a protrusion 233 having a certain height is formed. In FIG. 8B, a protrusion 233 having a certain height is formed along the three sides of the base 231 except the side on the one end 23X side. Although not shown in the drawings, a protrusion 233 having a fixed height may be formed along only one side of the base 231 on the other end 23Y side. In FIG. 8C, protrusions 233 having a certain height are formed in parallel along two sides of the base 231 along the longitudinal direction of the under tablet cassette 2.

  8D is formed by integrally forming a base portion 231 and a shaft support portion 232 of stainless steel or the like, and attaching a resin-made protruding portion 233 formed separately. In this embodiment, the lower surface protruding portion 233a, which is a part of the protruding portion 233, also protrudes to the lower surface side of the base portion 231. The lower surface protruding portion 233a can reduce friction when the bottom plate 23 moves relative to the support plate 3. In this embodiment, the sliding plates 311 and 321 in the support plate 3 can be omitted.

  9 differs from the above-described embodiments in that the bottom plate 23 has a flat plate shape similar to the conventional one and the shape of the supply rod 22 is changed. Specifically, the supply rod 22 of this embodiment includes an inner peripheral edge 221 and an outer peripheral edge 222 at the peripheral edge of the lower opening. The lower surface 221 a of the inner peripheral edge 221 is located above the lower surface 222 a of the outer peripheral edge 222. In this embodiment, the lower surface 22 b at the periphery of the lower opening coincides with the lower surface 222 a of the outer periphery 222. The bottom plate 23 can be brought into contact with the lower surface 221a of the inner peripheral edge 221. That is, the inner peripheral edge 221 and the outer peripheral edge 222 form a step at the periphery of the lower opening of the supply rod 22, and the bottom plate 23 in a state where the opening is prevented by the support plate 3 is located at this step.

  In the form shown in FIG. 9, the upper surface of the bottom plate 23 is positioned above the lower opening of the supply rod 22 (the opening at the position of the lower surface 222 a of the outer peripheral edge 222) in a state where the opening of the bottom plate 23 is prevented. To do. For this reason, the height H <b> 2 from the lower surface 222 a of the outer peripheral edge 222 to the upper surface of the bottom plate 23 can serve as an absorption allowance for absorbing the vertical displacement due to the gap between the support plate 3 and the under tablet cassette 2. Therefore, even in this embodiment, it is difficult to create a gap through which the tablet M unexpectedly passes between the supply basket 22 and the bottom plate 23 in a state where the opening of the bottom plate 23 is prevented.

  Although not shown, the bottom plate 23 in the form shown in FIG. 9 may be provided with the protruding portion 233 as in each of the embodiments described above.

Therefore, it is difficult to form a gap through which tablets or the like pass unexpectedly between the supply basket and the bottom plate in a state where the bottom plate is prevented from being opened by the bottom plate support member.

  Moreover, in this invention, the said baseplate shall be equipped with the part located in the said tablet accommodation space in the state which closed the said lower opening part.

  According to this, the said baseplate is provided with the part located in the said tablet accommodation space in the state which closed the said lower opening part. For this reason, the height dimension of the part located in the said tablet accommodation space can become an absorption margin which absorbs the position shift of the said baseplate by the clearance gap between the said baseplate and the said baseplate support member. Therefore, it is difficult to form a gap through which tablets or the like pass unexpectedly between the supply basket and the bottom plate in a state where the bottom plate is prevented from being opened by the bottom plate support member.

  In the present invention, the bottom plate includes a base portion and a protruding portion protruding upward from the base portion, and the base portion is located outside the tablet housing space in a state where the lower opening is closed, The protrusion can be positioned in the tablet storage space in the same state.

  According to this, the said protrusion part is located in the said tablet accommodation space in the state which closed the said lower opening part. For this reason, the height dimension by which the protrusion part is located in the tablet accommodating space can serve as an absorption margin for absorbing the position shift of the bottom plate due to the gap between the bottom plate and the bottom plate support member. Therefore, it is difficult to form a gap through which tablets or the like pass unexpectedly between the supply basket and the bottom plate in a state where the bottom plate is prevented from being opened by the bottom plate support member.

  In the present invention, the protrusion may be provided from one end to the other end in the horizontal direction.

  According to this, the said protrusion part is located in the said tablet accommodation space ranging from an end part to a front-end | tip part. For this reason, it can suppress that a clearance gap generate | occur | produces between the said bottom plates in the said whole supply rod.

  Further, in the present invention, the projecting portion may be configured such that the upper end portion of the projecting portion is inclined with respect to the base portion by projecting the portion closer to the other end portion than the portion closer to the one end portion. .

  According to this, even if the bottom plate includes a protruding portion, the protruding portion is not easily caught with respect to the peripheral edge of the lower opening of the supply rod as the bottom plate rotates, and the bottom plate rotates smoothly.

  In the present invention, the supply rod is configured such that the periphery of the lower opening includes an inner periphery and an outer periphery, and the lower surface of the inner periphery is above the lower surface of the outer periphery. It is located and the said baseplate can be contact | abutted with respect to the lower surface of the said inner periphery part.

  According to this, the said baseplate can be located in the level | step difference formed with the said inner periphery part and an outer periphery part. For this reason, the height dimension is such that the upper surface of the bottom plate is positioned higher than the lower surface of the outer peripheral edge due to the step, so that the displacement of the bottom plate due to the gap between the bottom plate and the bottom plate support member is absorbed. Can be an absorption fee. Therefore, it is difficult to form a gap through which tablets or the like pass unexpectedly between the supply basket and the bottom plate in a state where the bottom plate is prevented from being opened by the bottom plate support member.
