Therefore, in the present invention, the one and other moving rollers are moved to the left and right ends of the PTP sheet by rotating the adjusting shaft. When moving according to the position of the part, the left and right guide members also move as the adjustment shaft rotates.

  Further, in a sixth invention (invention according to claim 6), in the fifth invention, the one and the other moving rollers, the one and the other pressing rollers, and the other feeding roller, Insertion holes each having the same inner diameter are formed, and distortion prevention pins are inserted through these insertion holes.

  Further, a seventh invention (invention according to claim 7) is the above-mentioned fifth and sixth inventions, in which the feeding of the other than the engaging concave portion or the engaging convex portion formed in the one and the other moving rollers. The outer peripheral surfaces of the one and the other moving rollers located on the roller side cooperate with an engagement convex portion formed on the left and right guide members or a surface located closer to the one feed roller than the engaging concave portion. The PTP sheet is formed as a portion sandwiching both sides of the PTP sheet, and one or a plurality of protrusions are formed in a ring shape on the outer peripheral surface.

  An eighth invention (invention according to claim 8) is the invention according to any one of the fourth, fifth, sixth and seventh inventions, wherein the left and right guide members include the one and the other moving rollers. And a feed wheel that is rotatable while sandwiching the PTP sheet in cooperation with the outer peripheral surface of the PTP sheet.

  In the first invention (the invention described in claim 1), the adjustment shaft for changing the pressure roller to correspond to the interval between the recesses of the PTP sheet has the same center as the center of the rotation shaft. Therefore, a mechanism for changing the interval between the concave portions of the PTP sheet in the take-out device for the tablets or the like is provided in the rotating shaft, and the take-out device for the tablets or the like can be made smaller.

The PTP sheet can be sent out more reliably than when a force is applied only to one surface of the PTP sheet by using only the feed roller. Further, since the PTP sheet is sent out while being guided by the left and right guide members, the PTP sheet can be sent out while positioning more reliably, and the pressing roller can be reliably pressed into the concave portion of the PTP sheet.

  In the third invention (the invention described in claim 3), since the fixed shaft is urged by the elastic material in the direction of the rotation axis, the PTP sheet is surely secured even when the thickness of the PTP sheet is different. Can be sent out.

  In the fourth invention (invention according to claim 4), it is arranged so as to be rotatable in the rotation shaft, and the interval between the one and the other pressing rollers can be adjusted by the rotation operation of the adjustment shaft. Therefore, as in the first aspect of the invention, not only can the entire apparatus be reduced in size, but also there is very little distortion and resistance when moving the one and the other pressing rollers, and the adjustment described above. The shaft can be rotated smoothly.

  In the fifth invention (the invention described in claim 5), by rotating and operating the adjusting shaft, not only the one and the other moving rollers but also the left and right guide members are moved to the left and right at the same time. Since it can be adjusted according to the size, it is not necessary to provide another adjusting device for adjusting the left and right guide members, and the device for taking out tablets and the like can be made smaller.

  In the sixth invention (the invention described in claim 6), since one and the other moving roller, the one and the other pressing roller, and the other feeding roller are inserted with the anti-strain pin, the one and the other Due to the resistance of the left and right guide members that move as the moving roller moves, it is possible to effectively prevent the one and the other moving rollers from moving. That is, according to the sixth aspect of the invention, when the one and the other moving rollers are moved, the left and right guide members become resistances, and the one and the other moving rollers are inclined to rotate the adjusting shaft. The situation where the operation becomes impossible can be prevented by the distortion preventing pin.

  In the seventh invention (the invention described in claim 7), the left and right end portions of the PTP sheet to be fed are sandwiched between the outer peripheral surface of the one and the other moving rollers and the left and right guide members. Since one or a plurality of protrusions are formed on the outer peripheral surface of the other moving roller, the protrusions bite into the left and right ends of the PTP sheet. Therefore, even when the concave portion of the PTP sheet is pressed by one and the other pressing rollers, the left and right end portions of the PTP sheet are prevented from moving in the center direction (the one and the other feeding roller direction) due to the biting of the protrusions. Therefore, the one and the other pressing rollers can surely press the recess, so that the tablets and the like can be reliably taken out by the taking-out device for the tablets and the like.

  In the eighth invention (the invention described in claim 8), the left and right end portions of the PTP sheet to be fed are sandwiched between the outer peripheral surface of the one and the other moving rollers and the feeding wheel. It is possible to reliably take out the tablet by reliably applying the pressing force by the one and other pressing rollers to the formed recess. In particular, when one or a plurality of protrusions are formed on the outer peripheral surface like one and the other moving rollers constituting the seventh invention, the PTP sheet further cooperates with the feed wheel. The left and right ends of the tablet can be firmly sandwiched, and the tablets can be taken out more reliably.

In this state, when the handle 46 is rotated in the clockwise direction in FIG. 1, the follower 61 is urged toward the driving body 31 by the elastic force of the left elastic member 16 and the right elastic member 22. Therefore, the center of the lower end of the PTP sheet S is sandwiched between the drive feed roller 34 and the driven feed roller 63, and the left end side of the PTP sheet S is the left feed of the protrusion 37f of the left moving roller 37 and the left guide member 64. While being sandwiched between the ridge 66b of the wheel 66 and the right end side between the ridge 38f of the right moving roller 38 and the ridge 67b of the right feed wheel 67 of the right guide member 65, the discharge port It is moved in 10 directions. In this case, the PTP sheet S by the outer peripheral surface of the left pressure roller 35 and the right pressure roller 36, such as tablets S ₁ housed in the recess of the PTP sheet S is pressed against the back surface side, sealed by this pressure force sheet is broken, such as tablets S ₁ is pushed out to the outside. Then, the extruded tablet S ₁ falls into the drawer 11. The PTP sheet S is not always a constant thickness, but the distance between the driving body 31 and the driven body 61 is changed by the action of the left elastic material 16 and the right elastic material 22 in this way. Therefore, according to the present apparatus 1, even if the PTP sheet S is thick or thin, a force can be appropriately applied to the recess, and the tablet S ₁ can be It can be taken out. Further, in the present apparatus 1, since the outer peripheral surfaces of the driving feed roller 34 and the driven feed roller 63 are knurled, the rotation operation of the handle 46 is reliably transmitted to the PTP sheet S.
