An apparatus is described.
JP 2004-131149 A

  However, in such a tablet taking-out device, since all the pressing rollers are connected by a single shaft, there is a problem that when a short shaft is used, the tablet taking-out device cannot be used for a wide PTP sheet. Moreover, when a long shaft is used, there exists a problem that the whole tablet extraction apparatus will enlarge.

  This invention is made | formed in view of such a subject, and it aims at providing a small tablet taking-out apparatus applicable to many kinds of PTP sheets.

  The present invention adopts the following means in order to achieve at least one of the above objects.

The tablet taking-out device of the present invention comprises one or more holding rings, and a holding roller having a holding shaft that connects all of the holding rings,
Three or more movable rings, two fixed rings disposed on both ends of the three or more movable rings, and two or more connected to one of the fixed rings and at least one of the movable rings, respectively. A drive roller having a shaft and an elastic body disposed between the movable ring and the movable ring and between the movable ring and the fixed ring;
A fixing ring width adjusting means for adjusting a distance between the two fixing rings;
With
The holding roller is disposed at a position facing the driving roller,
All the movable rings and all the fixed rings are connected to at least one of the adjacent movable rings by any one of the shafts.

  In this tablet taking-out device, since all of the movable ring and the fixed ring are connected using a plurality of shafts, the length of each shaft is shortened compared to the case where all the rings are connected by one shaft. Can do. In other words, when all the rings are connected with one shaft, a shaft having a length that can be connected with all the rings spaced apart from each other is required. The width of the roller portion is longer than the length of the shaft. Cannot be shortened. On the other hand, when all the rings are connected by a plurality of shafts, a part of the plurality of shafts can be overlapped, so that the width of the roller portion can be further shortened. That is, this tablet taking-out device can be used even for a sheet having a short width compared to a case where all the rings are connected by one shaft.

    The tablet taking-out device of the present invention comprises a movable ring connecting shaft that connects at least two of the movable rings, and all the movable rings and all the fixed rings are the shafts or the movable ring connecting shafts. It may be connected to at least one of the adjacent movable rings by any one of them. In this way, all rings can be connected with a shorter shaft. That is, this tablet taking-out apparatus can be used for a sheet having a shorter width.

  In the tablet dispensing device of the present invention, the center of the movable ring may coincide with the center of gravity of the position of the intersection of the movable ring and the shaft or the movable ring connecting shaft. In this way, when positioning the position of the movable ring, an elastic force acts in a direction parallel to the shaft from the elastic body to the movable ring, so that the movable ring can be moved in parallel. That is, it is possible to reduce the force applied to the shaft when positioning the position of the movable ring.

  The tablet take-out device of the present invention may include a sheet supply unit that has a sheet holding unit for holding the sheet at both ends and supplies the sheet between the drive roller and the holding roller. In this way, since the sheet can be guided to an appropriate position between the driving roller and the holding roller, the trouble of adjusting the sheet position can be reduced. The tablet taking-out device of the present invention adopting this aspect may include sheet holding portion width adjusting means for adjusting the lateral width of the sheet supply means. By so doing, the width of the sheet supply means can be adjusted in accordance with the width of the sheet, and therefore the present invention can be applied to sheets having various widths.

  In the tablet take-out device of the present invention, the holding roller has three or more holding rings, a holding shaft connecting all of the holding rings, and an elastic body arranged between two adjacent holding rings. And holding ring width adjusting means for adjusting the interval between the holding rings arranged on the outermost side. By doing so, the interval between the holding rings provided on the holding roller can be adjusted, so that the tablet can be prevented from being prevented from being taken out by the holding ring.

  The tablet taking-out device of the present invention includes a holding portion that can receive the holding rings adjacent to each other, and the receiving portion is compliant when at least a part of one of the holding rings enters at least a part of the other. May be. In this way, there is a case where dust adheres between the adjacent holding rings or a case where the holding ring is easily rotated by applying oil between the adjacent holding rings. However, it is possible to prevent the dust residue and the oil residue from falling down. That is, the taken-out tablet can be prevented from being contaminated by dust residue or oil residue.

  In the tablet dispensing apparatus of the present invention, the fixed ring width adjusting means may be shared with at least one of the holding ring width adjusting means and the sheet holding portion width adjusting means. In this case, when the holding ring width adjusting means or the sheet holding portion width adjusting means is operated, the fixing ring width adjusting means is simultaneously operated. Therefore, labor can be reduced as compared with the case where the holding ring width adjusting means is operated separately. .

  In the tablet dispensing device of the present invention, the drive roller includes a drive shaft, a center ring fixed to the center of the drive shaft, the movable ring disposed on both sides of the center ring, and both end sides of the movable ring. Two fixed rings disposed on the shaft, the shaft connecting one of the fixed rings and at least one of the movable rings, and at least one disposed on both sides of the central ring and the central ring. The central shaft connecting the movable ring, and the elastic body disposed between the movable ring and the movable ring, between the movable ring and the fixed ring, or between the central ring and the movable ring; , May be included.

FIG.

  As shown in FIG. 1, the tablet take-out device 10 of the present invention includes a drive handle 12 provided on the left side, a drive roller 20 connected to the drive handle 12, and a holding roller provided at the back of the drive roller 20. 40 (see FIG. 2), a sheet holding unit 70 provided above the boundary surface between the driving roller 20 and the holding roller 40, and a tablet collection provided below the boundary surface between the driving roller 20 and the holding roller 40 A unit 80, a distance adjusting unit 60 connected to the driving roller 20, the holding roller 40, and the sheet holding unit 70, and a distance adjusting handle 14 connected to the distance adjusting unit 60 are provided.

  As shown in FIG. 3, the driving roller 20 includes four pressing rings 24 a to 24 d (hereinafter also referred to as “pressing rings 24”), and gripping rings 26 a to 26 that are disposed between the pressing rings 24. A ring 26c (hereinafter also referred to as "gripping ring 26"), a fixing ring 22a and a fixing ring 22b (hereinafter also referred to as "fixing ring 22") disposed on both outer sides of the pressing ring 24, and the respective rings and rings And a drive shaft 30 that is a central part of the drive roller 20 and that can connect all of the pressing ring 24, the grip ring 26, and the fixing ring 22. The drive roller 20 is rotatably attached to the central position of the main body of the tablet take-out device 10 by a drive shaft 30. Further, since the driving roller 20 communicates with the driving handle 12, when the driving handle 12 is rotated, the driving roller 20 also rotates simultaneously with the driving handle 12. As shown in FIG. 2, the fixing ring 22 has a fixing plate 62a on the fixing ring 22a and a fixing plate 62b on the fixing ring 22b. With the movement of the plate 62b (hereinafter also referred to as “fixing plate 62”), the fixing ring 22 also moves. As shown in FIG. 3, end portions of left shafts 32 a to 32 c (hereinafter also referred to as “left shaft 32”) are fixed to the fixing ring 22 a, and the fixing ring 22 a and the pressing ring are fixed by the left shaft 32. 24a, the grip ring 26a, and the pressing ring 24b can be connected. A torsion spring 28 is provided around the left shaft 32 and between each ring. At this time, since the left shaft 32 is fixed so that the center of gravity of the contacts of the three left shafts 32 and the rings and the centers of the rings are at the same position, the elastic force of the torsion spring 28 is It will be added approximately evenly to the sides of each ring. Further, the centers of the three central shafts 34 a to 34 c (hereinafter also referred to as “central shaft 34”) are fixed to the grip ring 26 b, and the pressing ring 24 and the grip ring 26 are communicated with each other. At this time, the left shaft 32 and the center shaft 34 are adjacent to each other, and are arranged at positions that are the apexes of a substantially regular hexagon. That is, the center of gravity of the intersection of the left shaft 32 and the central shaft 34 with each ring coincides with the center of each ring. The right shafts 36a to 36c (hereinafter also referred to as “right shaft 36”) fixed to the fixing ring 22b are the same as the left shaft 32 fixed to the fixing ring 22a, and thus the description thereof is omitted here. .

  As shown in FIG. 4, the holding roller 40 includes a holding ring 43 to a holding ring 45, a fixing ring 42 and a fixing ring 46 arranged on the outside of the holding ring 43 and the holding ring 45, and each ring and ring. And a holding shaft 41 that connects all of the holding rings 43 to 45, the fixing ring 42, and the fixing ring 46 to each other. For this reason, due to the elastic force of the torsion spring 47, the intervals between the adjacent rings are kept substantially the same. The holding roller 40 is constituted by a free roller, and is attached to the main body of the tablet take-out device 10 by a holding shaft 41 so as to be rotatable. As shown in FIG. 2, the holding shaft 41 is attached in the direction from the left and right ends of the holding roller 40 to the driving roller 20 by a biasing spring 16a and a biasing spring 16b (hereinafter also referred to as “biasing spring 16”). It is energized. For this reason, since the distance between the driving roller 20 and the holding roller 40 is appropriately determined depending on the thickness of the PTP sheet 90, the thickness of the PTP sheet 90 is not affected by the thickness of the PTP sheet 90. The PTP sheet 90 can be conveyed by appropriately applying a contact force.

  Here, the retaining ring 43 will be described in more detail. As shown in FIG. 5, the holding ring 43 has a holding portion 43a having irregularities on the circumferential surface, a cylindrical female portion 43b on one side of the holding ring 43, and a surface opposite to the female portion 43b. And a male part 43c, and a hole through which the holding shaft 41 can penetrate the central part. The diameter of this hole is slightly longer than the diameter of the holding shaft 41, but slightly shorter than the torsion diameter of the torsion spring 47. For this reason, one end of the torsion spring 47 provided around the holding shaft 41 is stopped by the holding ring 43. The diameter of the male part 43c is slightly longer than the diameter of the female part 43b. When the holding ring 43 and the adjacent holding ring 44 are close to each other, the male part of the holding ring 44 is located inside the female part 43b. 44c enters, and a part of female part 43b and male part 44c overlap. By doing so, the overlapping portion of the female portion 43b and the male portion 44c is not exposed to the outside, so even if dust residue or oil residue is attached between the female portion 43b and the male portion 44c, the retaining ring It can prevent falling to the lower part of 43.

  As shown in FIG. 2, the distance adjusting unit 60 includes a fixing plate 62 that respectively contacts the fixing ring 22 and the fixing ring 46, and a connecting portion 64 a and a connecting portion 64 b that are screwed to the spiral rod 66 (hereinafter referred to as “connecting portion 64”). And a spiral bar 66 having one end connected to the spacing adjustment handle 14, and a reception bar 68a and a reception bar 68b (hereinafter, also referred to as a "response bar 68") that meet a sheet holding unit 70 described later. I have. The spiral rod 66 is formed with a screw groove so that the spiral direction is symmetrical with respect to the center. The fixing plate 62a and the mating bar 68a are fixed to the connecting portion 64a, and the fixing plate 62b and the mating bar 68b are fixed to the connecting portion 64b, respectively, and the connecting portion 64 is screwed at positions symmetrical with respect to the center of the spiral bar 66. Are combined. For this reason, when the spiral rod 66 is rotated in one direction, the connecting portions 64 move toward or away from each other according to the thread groove. That is, the interval between the fixed plate 62 and the receiving rod 68 can be adjusted by rotating the interval adjusting handle 14.

  As shown in FIG. 6, the sheet holding unit 70 includes a grip plate 72 a and a grip plate 72 b (hereinafter also referred to as “grip plate 72”) disposed on the left and right ends, and movable plates 74 a to 74 c disposed in the center. (Hereinafter also referred to as “movable plate 74”), a connecting shaft 76a and a connecting shaft 76b that connect the gripping plate 72a and the movable plate 74a, and the gripping plate 72b and the movable plate 74c, respectively (hereinafter also referred to as “connecting shaft 76”). And a movable plate connecting shaft 78a and a movable plate connecting shaft 78b (hereinafter also referred to as “movable plate connecting shaft 78”) for connecting the movable plate 74, and between the gripping plate 72 and the movable plate 74 or the movable plate 74, respectively. The torsion spring 79 is provided. The torsion spring 79 keeps the gap between the gripping plate 72 and the movable plate 74 at a constant interval. Further, the torsion springs 79 are arranged around the respective shafts, and the respective shafts are arranged at symmetrical positions with respect to the center of the gripping plate 72 or the movable plate 74, so that the torsion arranged around the shafts. The spring 79 is pressed parallel to the lateral surface of each plate. The sheet holding unit 70 is detachably attached to the tablet take-out device 10 when the gripping plate 72a and the gripping plate 72b are respectively engaged with the acceptance rod 18a and the acceptance rod 18b.

  As shown in FIG. 1, the tablet collection unit 80 is disposed at the lower part of the tablet extraction device 10, has a drawer shape having a handle 82 on the front surface, and has a mesh-shaped bottom surface 84. The stitches of the bottom surface 84 are finer than the general tablet size, and the tablet 92 pushed out by the pressing ring 24 falls and is held on the bottom surface 84. On the other hand, dust or the like smaller than the tablet 92 passes through the stitches and is not held on the bottom surface 84. For this reason, it is possible to selectively collect the tablets 92 and prevent the tablets 92 taken out by dust or the like from being contaminated. Moreover, since the handle 82 is provided on the entire surface, the tablet collection unit 80 can be easily detached.

  Next, the usage method of the tablet extraction apparatus 10 of this Embodiment comprised in this way is demonstrated. FIG. 7 is a top view showing a state in which the PTP sheet 90 is set in the tablet dispensing device 10. When taking out the tablet 92 from the PTP sheet 90, the PTP sheet 90 is set in the sheet holding unit 70 as shown in FIG. At this time, the interval described later is set so that the position of the outer side surface of the tablet 92 enclosed in the outermost side of the PTP sheet 90 matches the position of the inner side surface of the gripping plate 72 disposed at both ends of the sheet holding unit 70. The width of the sheet holding unit 70 is adjusted in advance using the adjustment unit 60. The interval adjusting unit 60 adjusts the interval of the sheet holding unit 70 and also adjusts the interval of the rings provided in the driving roller 20 and the holding roller 40. When adjusted, the positions of all the rollers are adjusted to an appropriate positional relationship when taking out the tablets 92 from the PTP sheet 90. That is, the PTP sheet 90 is disposed substantially perpendicular to the drive roller 20 and the holding roller 40, and can be led to a position where the tablet 92 can be appropriately taken out from the PTP sheet 90.

  Here, a method of adjusting the width of the sheet holding unit 70 will be described in detail with reference to FIG. As described above, in the sheet holding unit 70, the gripping plate 72 a and the gripping plate 72 b are respectively mated with the mating bar 68 a and the mating bar 68 b, and the mating bar 68 is fixed to the connection portion 64 of the spacing adjustment unit 60, respectively. ing. For this reason, when the interval of the acceptance bar 68 is adjusted by the interval adjusting unit 60, the interval of the gripping plate 72 is adjusted. At this time, the intervals of the gripping plate 72a, the gripping plate 72b, and the movable plate 74 are kept at regular intervals by the torsion springs 79 arranged therebetween. Since the tablets 92 enclosed in the PTP sheet 90 are enclosed in the PTP sheet 90 at equal intervals, the grip plate 72 or the movable plate 74 is positioned between the tablet 92 and the tablet 92 as shown in FIG. The PTP sheet 90 can be held. Further, the inner side surface of the holding plate 72 and the side surface of the movable plate 74 are positioned at substantially the same position as the side surface of the tablet 92, and even if the PTP sheet 90 is carried in by the driving roller 20, the PTP sheet is not inclined. The PTP sheet 90 can be guided to a position facing the pressing roller 24.

  Next, a method for adjusting the interval between the fixing rings 22 of the driving roller 20 will be described. As described above, since the fixing ring 22 is in contact with the fixing plate 62, when the interval adjusting handle 14 is rotated, the fixing ring 22 also moves with the movement of the fixing plate 62. When the fixing ring 22 moves, the respective rings provided on the driving roller 20 are pressed by the torsion spring 28 and are arranged at positions where the intervals are substantially equal. Therefore, the fixing ring 22 grips both ends of the PTP sheet 90, the grip ring 26 grips the portion between the tablet 92 and the tablet 92 of the PTP sheet 90, and each ring rotates to transport the PTP sheet 90. . At the same time, the pressing ring 24 is positioned at a position opposite to the encapsulated portion of the tablet 92, presses the tablet 92, and the tablet 92 is pushed out from the PTP sheet 90. Note that the movement of positioning the respective rings is the same as the movement of the plates of the sheet holding unit 70 arranged at equal intervals, and the description thereof is omitted here.

  Here, the open state and the closed state of the drive roller 20 will be described in more detail with reference to the drawings. FIGS. 7A and 7B are explanatory diagrams showing the open state and the closed state of the drive roller 20. FIG. 7A shows the closed state, and FIG. 7B shows the open state. In the closed state, as shown in FIG. 7A, all the fixing rings 22, the pressing rings 24, and the gripping rings 26 are adjacent to each other. At this time, the central shaft 34 connects all the rings between the fixed ring 22, the left shaft 32 connects all the rings from the fixed ring 22a to the grip ring 26a, and the right shaft 36 grips from the fixed ring 22b. All the rings up to the ring 26a are connected. On the other hand, in the open state, as shown in FIG. 7B, the fixing ring 22, the pressing ring 24, and the gripping ring 26 are pressed by the torsion spring 28 and are positioned at substantially the same interval. At this time, the central shaft 34 connects all the rings except the fixing ring 22, the left shaft 32 connects the fixing ring 22a, the pressing ring 24a, and the grip ring 26a, and the right shaft 36 connects the fixing ring 22b and the pressing ring 24d. And the grip ring 26d are connected. That is, as shown in FIG. 7B, all the rings are not connected by the central shaft 34. By doing so, even if the length of the central shaft 34 is necessary and sufficient for connecting all the rings in the closed state, all the rings can be connected in the open state.

  Note that the method for adjusting the distance between the holding rings 43 provided in the holding roller 40 is the same as the method for adjusting the distance between the pressing ring 24 and the grip ring 26 provided in the driving roller 20. Then, explanation is omitted.

  Again, it returns to description of the usage method of the tablet extraction apparatus 10 of this invention. When the PTP sheet 90 is set in the rear part of the sheet holding unit 70 adjusted to an appropriate width with respect to the width of the PTP sheet 90, the leading end of the PTP sheet 90 is connected to the grip ring 26 of the driving roller 20 and the holding roller. It is led between 40 retaining rings 43. As described above, since the holding roller 40 is urged in the direction of the driving roller 20 by the urging spring 16, the leading end portion of the PTP sheet 90 is held between the grip ring 26 and the holding ring 43.

  Next, when the operator rotates the drive handle 12, the drive roller 20 and the grip ring 26 rotate, and the friction between the surface of the grip ring 26 and the surface of the PTP sheet 90 causes the PTP sheet 90 to rotate. The take-out device 10 is guided downward. When the PTP sheet 90 moves downward to a position where the tablet 92 is enclosed, the tablet 92 is pressed by the pressing ring 24 positioned at a position facing the tablet 92. At this time, since the holding ring 43 is positioned at a position facing the grip ring 26, the tablet 92 is taken out from the PTP sheet 90. The taken-out tablet 92 falls by gravity and is collected by the tablet collection unit 80.

  Next, the operator can take out the tablet collection unit 80 by pulling the handle 82 attached to the tablet collection unit 80 toward the front surface of the tablet removal device 10. By doing so, the tablets 92 taken out from the PTP sheet 90 can be easily collected.

  According to the tablet take-out device 10 of the present embodiment described in detail above, the left shaft 32, the central shaft 34, and the right shaft 36 connect all of the fixing ring 22, the pressing ring 24, and the grip ring 26 with one shaft. Compared with the case where all the rings are connected with each other, all the rings can be connected with a shorter shaft. That is, at least a part of the left shaft 32, the central shaft 334, and the right shaft 36 overlap, so that the interval between the fixing rings 22 can be narrowed compared to the case where the one shaft is connected. By doing so, the tablet take-out device 10 can be used even for the narrow PTP sheet 90. In addition, since the intervals between the pressing rings 24 are set to be equal to each other according to the interval between the fixing rings 22, the interval between the fixing rings 22 can be reduced, which means that the interval between the pressing rings 24 is reduced. Means you can. That is, the tablet take-out device 10 can be used for various types of PTP sheets such as a PTP sheet in which smaller tablets are encapsulated and a PTP sheet in which the interval between tablets adjacent in the lateral direction is narrow.

  The torsion spring 28 is positioned around the left shaft 32, the center shaft 34, and the right shaft 36, and these shafts are positioned at the apexes of a substantially regular hexagon centering on the midpoint of the pressing ring 24 and the grip ring 26. Therefore, the torsion spring 28 presses the pressing ring 24 and the grip ring 26 in the direction parallel to the respective shafts. In this way, when adjusting the distance between the rings, the force applied to the shaft can be reduced, which contributes to maintaining the durability of the shaft.

  Further, the sheet holding unit 70 has gripping plates 72 on both sides, and positions the PTP sheet 90 at a position between the driving roller 20 and the holding roller 40. By doing so, it is possible to save the trouble of arranging the PTP sheet 90 at an appropriate position and to prevent malfunction due to the PTP sheet 90 not being arranged at an appropriate position. At this time, since the interval adjusting unit 60 that adjusts the interval between the gripping plates 72 is provided, the interval between the gripping plates 72 can be adjusted in accordance with the lateral width of the PTP sheet 90. Therefore, the tablet taking-out device 10 can be used for PTP sheets 90 having various widths.

  Furthermore, in the holding roller 40, when the interval between the fixing ring 42 and the fixing ring 46 is adjusted by the interval adjusting unit 60, the holding rings 43 to 45 are equally spaced by a torsion spring 47 provided around the holding shaft 41. Is positioned. By doing so, the holding rings 43 to 45 are positioned at positions facing the grip ring 26 of the driving roller, and therefore, the holding rings 43 to 45 do not hinder the taking of the tablets 92 when taking out the tablets 92.

  The holding ring 43 has a female part 43b and a male part 43c, and the male part 44c and the female part 43b of the adjacent holding ring 44 can meet each other. The diameter of the female part 43b is slightly larger than the diameter of the male part 44c. Since it is long, when the male part 44c and the female part 43b meet, the male part 44c enters inside the female part 43b. By doing so, even if dust residue or the like is accumulated between the retaining ring 43 and the retaining ring 44, the dust residue or the like does not fall. That is, it is possible to prevent the extracted tablet 92 from being contaminated by dust residue. Further, since the female portion 43b and the male portion 44c cover the surface of the holding shaft 41, the force applied to the shaft 41 can be reduced.

  Further, the connecting portion 64 of the interval adjusting unit 60 is fixed to the fixing plate 62 and the mating bar 68, respectively. The fixing plate 62 is fixed to the fixing ring 22, the fixing ring 42, and the fixing ring 46, and the fixing plate 62 and the receiving bar 68 are in contact. For this reason, by operating the interval adjusting unit 60 using the interval adjusting handle 14, all the intervals of the driving roller 20, the holding roller 40, and the sheet holding unit 70 can be adjusted at a time. That is, the operator's labor can be reduced.

  It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be implemented in various modes as long as it belongs to the technical scope of the present invention.

  For example, instead of the above-described embodiment, as shown in FIG. 9, the lengths of the left shaft 32 and the right shaft 36 may be increased and the central shaft 34 may not be used. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the left shaft 32, the center shaft 34, and the right shaft 36 are each used three, but the midpoint of the pressing ring 24 and the grip ring 26 and the center of gravity of each shaft coincide with each other. If it is arranged, it may be two or four or more. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, three left shafts 32, central shafts 34, and right shafts 36 are used, but one may be used. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the central shaft 34 is fixed to the grip ring 26b. However, the central shaft 34 may not be fixed, may be fixed to the grip ring 26a or the grip ring 26c, and may be pressed. It may be fixed to any one of the rings 24. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the torsion spring 28 or the torsion spring 47 is arranged around the circumference of each shaft connecting the rings, but one ring has the same elastic force from both sides. The torsion spring 28 or the torsion spring 47 does not have to be arranged around all shafts. For example, the torsion spring 28 or the torsion spring 47 may be disposed on one of the shafts connecting the rings. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the torsion spring 28 or the torsion spring 47 is arranged between the rings. However, the torsion spring is not limited to the torsion spring as long as it has an elastic force. It may be natural rubber or elastic fiber. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the interval adjusting unit 60 is used to adjust all the intervals of the driving roller 20, the holding roller 40, and the sheet holding unit 70. However, the respective intervals may be adjusted here. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, two shafts are arranged at symmetrical positions with respect to the center of the gripping plate 72 or the movable plate 74 of the sheet holding unit 70, but the number of shafts may be one. Two or more shafts may be in an asymmetric position. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the female part 43b and the male part 44c meet each other. However, a lubricant such as grease or oil may be applied between the female part 43b and the male part 44b. By so doing, friction between the retaining ring 43 and the retaining shaft 41 can be reduced.

  In the above-described embodiment, the drive roller 20 and the drive handle 12 are connected, and the drive roller 20 is rotated by rotating the drive handle 12. However, instead of the drive handle 12, a motor or the like is connected, The drive roller 20 may be rotated by rotation of a motor or the like. In this way, the trouble of rotating the drive handle 12 can be reduced.

  The present invention can be used when taking out a tablet enclosed in a PTP sheet. In particular, in facilities that use a large number of tablets such as hospitals, it takes a lot of time to take out the tablets, so the effectiveness of using the present invention is high.
