In a structure of the packaging apparatus, the packaging paper roll having a packaging paper wound around a shaft member in a roll shape is attached in a predetermined position, an end of the packaging paper is drawn from the roll, and the paper is passed through various rollers, solid preparation chute section, heat seal mechanism, and the like.
- Such a conventional
packaging paper roll 100 and a packagingapparatus rotation shaft 101 with the roll attached thereto are shown in FIGS. 9 to 11. The conventionalpackaging paper roll 100 is constituted of a hollow tubular shaft member (hereinafter referred to as a paper tube) 102 of a boxboard shown in FIG. 10, and apackaging paper 20 wound around the member. Thepackaging paper 20 is used to contain and package the solid preparation, and constituted of a thermally fusible thin paper using an auxiliary medium of polyethylene or another thermally fusible material which melts at a predetermined temperature. The longitudinal paper with a predetermined width is wound around theshaft member 102 in a roll shape. - Moreover, the
packaging paper 20 is folded into two from substantially a central portion of a width direction, and doubly folded/bent. A double folded/bent portion forms a foldedportion 20A, and opposite ends of the double folded/bent portion form an opening 20B (on a side opposite to the foldedportion 20A). Thepackaging paper 20 is wound around theshaft member 102 in a double folded state, and thewound packaging paper 20 is drawn from a terminal end of the paper. - On the other hand, the
rotation shaft 101 with thepackaging paper roll 100 attached thereto is rotatably and vertically formed in a not-shown packaging apparatus, and a disc-shaped base plate 103 is disposed in a bottom portion of the roll. A plurality ofspring members 104 directed downward from an upper end, expanding outwardly and descending are attached to a periphery of therotation shaft 101, and abrake 106 driven by a solenoid is disposed under thebase plate 103. Thebrake 106 abuts on the base plate 103 (rotation shaft 101), applies a resistance to rotation of the shaft and is disposed in order to adjust a tension applied to the drawnpackaging paper 20. - Moreover, when the
packaging paper roll 100 is attached to therotation shaft 101, therotation shaft 101 is inserted intoshaft member 102 and thepackaging paper roll 100 is laid on thebase plate 103. In this case, thespring member 104 of therotation shaft 101 expands outside from an inner diameter of theshaft member 102 in a stationary state, and therotation shaft 101 advances into theshaft member 102 while thespring member 104 is compressed inward by theshaft member 102. Thereby, thespring member 104 is pressed onto an inner peripheral surface of theshaft member 102 by its restoring force. - When the solid preparation is packaged, the
packaging paper 20 is drawn from thepackaging paper roll 100 attached to therotation shaft 101, disposed along a predetermined path and used. However, since theconventional spring member 104 is pressed and connected to the inner peripheral surface of theshaft member 102, a slip is inevitably caused by deterioration with age. If thespring member 104 slips on the inner peripheral surface of theshaft member 102, a disadvantage occurs: even when the tension is applied to thepackaging paper 20 as described above and the paper tries to be drawn, only thepackaging paper roll 100 freely rotates. - In order to solve this problem, the
spring member 104 is strengthened, or extended more outwardly so that a press-contact strength of thespring member 104 andshaft member 102 is increased. In this case, when the newpackaging paper roll 100 is attached torotation shaft 101, or when theshaft member 102 of the usedpackaging paper roll 100 is pulled from therotation shaft 101, an excessively large force is required, and a replacing operation becomes excessively troublesome. - The present invention has been developed to solve the aforementioned conventional technical problem, and an object thereof is to provide a solid preparation packaging apparatus and a packaging paper roll for a solid preparation in which a slip can be prevented from being generated between a packaging paper roll and a rotation shaft with the roll attached thereto by a simple constitution without inhibiting a replacing operation.
- According to the present invention, there is provided a solid preparation packaging apparatus comprising: a plurality of tablet cases in which respective types of solid preparations are contained; and a thermally fusible packaging paper wound around in a roll shape, so that the solid preparation discharged from the tablet case is packaged in the packaging paper, wherein the packaging paper is wound around a periphery of a shaft member detachably attached to a rotation shaft to form the roll shape, an engaging portion is formed in the rotation shaft, and an engaged portion attachably/detachably joined to the engaging portion is formed in the shaft member.
- Moreover, in the solid preparation packaging apparatus of the present invention, the aforementioned engaging portion is formed to project outside from a base portion of the rotation shaft disposed in an upright manner, the shaft member has a hollow tubular shape, and the engaged portion is notched/formed in an edge of the shaft member.
- Furthermore, in the solid preparation packaging apparatus of the present invention, a plurality of engaging portions and engaged portions are formed.
- Additionally, according to the present invention, there is a packaging paper roll for a solid preparation, comprising: a hollow tubular shaft member; and a thermally fusible packaging paper wound around a periphery of the shaft member, wherein a notch is formed in an edge of the shaft member.
- Moreover, in the packaging paper roll for the solid preparation of the present invention, a plurality of notches are formed.
- Furthermore, in the packaging paper roll for the solid preparation, the notch is formed by cutting an edge of the shaft member to an outer portion from an inner portion of the edge.
- Additionally, in the packaging paper roll for the solid preparation of the present invention, the notch is formed such that an inner portion of an edge of the shaft member is cut/removed, and an outer portion thereof remains uncut.
- According to the present invention, since the engaged portion is formed in the shaft member with the packaging paper wound therearound in the roll shape, the engaging portion formed on the rotation shaft of the solid preparation packaging apparatus with the shaft member attached thereto is attachably/detachably joined into the engaged portion, so that the slip between the rotation shaft and the shaft member can be prevented.
- In this case, since a spring member is not pressed onto the shaft member as in a conventional art, it is extremely easy to attach/detach the shaft member to/from the rotation shaft, and therefore a replacing operation of the packaging paper roll is not inhibited. Particularly, when the engaging portion is formed to project outside from the base portion of the rotation shaft disposed in an upright manner, and the engaged portion is notched/formed in the edge of the hollow tubular shaft member, the engaging portion engages with the engaged portion in a final stage of a series of operation for inserting the rotation shaft into the shaft member, and therefore attaching operability is further enhanced.
- Moreover, when a plurality of engaging and engaged portions are formed, an engaging relation of the shaft member and rotation shaft is further strengthened, and the slip can more firmly be prevented from occurring.
- Furthermore, when the notch is formed by cutting the edge of the shaft member to the outer portion from the inner portion of the edge, the shaft member is easily formed, and a rise of component cost can be minimized.
- Additionally, the notch is formed such that the inner portion of the shaft member edge is cut/removed and the outer portion thereof remains uncut. Then, a disadvantage that the edge of the shaft member is collapsed by a pressure during winding of the packaging paper can be prevented or inhibited.

preparation packaging apparatus 1 of the present invention is installed in a hospital, dispensing pharmacy, and the like, and constituted of a solidpreparation containing mechanism 3 disposed in a rectangularouter case 2, and the solidpreparation packaging mechanism 14 disposed under the containing mechanism. Atablet case container 5 of the solidpreparation containing mechanism 3 is constituted in an upper portion of theouter case 2, and an upper surface opening of thetablet case container 5 is openably/closably closed by a top table 4. - A plurality of
tablet cases 6 . . . are contained in thetablet case container 5, and asub-container 7 is disposed in a front upper portion of the container. Thesub-container 7 contains a solid preparation (e.g., a half cut tablet, and the like) which cannot be contained in thetablet case 6, and a not-shown belt conveyor (which may be connected via a chain, gear, and the like in this case) is driven by a belt 9 extended to a not-shown rotation shaft pulley of amotor 8. Moreover, a plurality ofcontainer divisions 7A are continuously disposed in the belt conveyor. - Moreover, discharge counters such as a not-shown photosensor are disposed under the
respective tablet cases 6 . . . The discharge counter is connected to the respective upper-side tablet cases 6 . . . , and a motor driven type discharge drum is built in the counter. Furthermore, the discharge drum is structured such that solidified preparations such as a tablet, capsule, pill, and troche are inserted in one upper/lower row into a plurality of grooves in a side surface of the drum. Additionally, when the discharge drum rotates, the solid preparations are dropped one by one from each groove, and the number of the solid preparations is detected and counted by the photosensor. - Moreover, a drop path is formed in one end of the
sub-containers 7 . . . , and connected onto aturntable 10 described later. In the constitution, each solid preparation is contained in thecontainer division 7A of thesub-container 7 as described above, and the solid preparations in therespective container divisions 7A . . . drop one by one onto theturntable 10 from the drop path during rotation of themotor 8 by an operator's switch operation. - The disc-shaped
turntable 10 for collecting the solid preparations is disposed under therespective tablet cases 6 . . . and the drop path, and thisturntable 10 has a corresponding area under all thetablet cases 6 . . . and drop path. Aridge 10A raised in a conical shape is formed in a center portion of theturntable 10, and theturntable 10 is rotated/driven at a predetermined speed by a not-shown turntable motor disposed under theridge 10A. - Moreover, an
annular guide 11 is disposed in an upright manner around theturntable 10, and a discharge port D is notched/formed in an appropriate portion of theguide 11. Achute 13 described later is disposed under the discharge port D, and in the constitution the solid preparations gathered on aguide 11 side by rotation of theturntable 10 drop into thechute 13. Thischute 13 has an inverse four-sided truncated pyramid shape, the upper end opening thereof is disposed opposite to the discharge port D of theturntable 10, and a lower open end (tip end) thereof is disposed above the two-foldedpackaging paper 20 described later. - On the other hand, the solid
preparation packaging mechanism 14 is disposed under theturntable 10. The solidpreparation packaging mechanism 14 is constituted by disposing attaching means for attaching thepackaging paper roll 19, guide means for guiding the drawnpackaging paper 20 into a predetermined position, and drawing means for pulling a tip end of thepackaging paper 20 on abase 15. The packaging paper attaching means is, as shown in FIG. 3, constituted of arotation shaft 16 rotatably and vertically disposed on thebase 15, a disc-shapedbase plate 17 positioned in a bottom of therotation shaft 16 and projecting outside, a solenoid drivenbrake 18 disposed under the base plate 17 (between the base plate and the base 15), and the like. - The
rotation shaft 16 has a cylindrical shape with an outer diameter which is substantially equal to (or slightly smaller than) an inner diameter of theshaft member 21 of thepackaging paper roll 20 described later, and a plurality of engagingportions 16A projecting outside from the periphery at a constant interval are formed on a base portion as abase plate 17 side. This engagingportion 16A has a height of about 5 to 10 mm, and an outward projecting size thereof is substantially equal to a thickness of theshaft member 21. Moreover, therotation shaft 16 is attachably/detachably inserted and fit into theshaft member 21 of thepackaging paper roll 19. - Here, the
packaging paper roll 19 of the present invention will be described. As shown in FIG. 5, thepackaging paper roll 19 is constituted of the hollow tubular shaft member (usually referred to as a paper tube) 21 of a boxboard (a hard synthetic resin may be used), and thepackaging paper 20 wound around the member. Thepackaging paper 20 is used to contain and package the solid preparation, and constituted of a thermally fusible thin paper using an auxiliary medium of polyethylene or another thermally fusible material which melts at a predetermined temperature. The longitudinal paper with a predetermined width is wound around theshaft member 21 in the roll shape. - Moreover, the
packaging paper 20 is folded into two from substantially a central portion of a width direction, and doubly folded/bent. A double folded/bent portion forms a foldedportion 20A, and opposite ends of the double folded/bent portion form anopening 20B (on a side opposite to the foldedportion 20A). Thepackaging paper 20 is wound around theshaft member 21 in a double folded state while the foldedportion 20A is disposed on a lower edge of theshaft member 21. Thewound packaging paper 20 is drawn from a terminal end of the paper (FIG. 4). - Furthermore, as shown in FIG. 5, a plurality of engaged
portions 21A are notched/formed at a constant interval around a lower edge of theshaft member 21 of thepackaging paper roll 19 of the present invention. The engagedportion 21A is formed by cutting the lower edge of theshaft member 21 to the outer portion from the inner portion of the edge in a rectangular shape, and sized and disposed such that the engagingportion 16A of therotation shaft 16 can substantially tightly be fitted. - On the other hand, a
tension lever 23 is disposed as guide means beside therotation shaft 16 in the solidpreparation packaging mechanism 14, and thetension lever 23 is extended between tworollers roller 24 is fixed to thebase 15, and theroller 25 can rock centering on theroller 24. The roller is biased in a direction apart from therotation shaft 16 by a not-shown spring member. Moreover, a position of thisroller 25 is detected by a not-shown switch. Additionally, aguide roller 26 is vertically disposed on thebase 15 beside theroller 24. - A drawing
roller 30 as drawing means is disposed on thebase 15 on a opposite side of thetension lever 23 via therotation shaft 16. The drawingroller 30 is constituted of a pair of narrow rubber rollers (i.e., rollers of a natural rubber, synthetic rubber, and the like) 33, 33A, and rotatably attached to upper ends ofrotation shafts rotation shaft 32 with onerubber roller 33 attached thereto is a rotation shaft of a drawingmotor 31. - Furthermore, the
rotation shaft 34 of theother rubber roller 33A is biased by a not-shown coil spring, onerubber roller 33A is pressed onto therubber roller 33 with a predetermined pressure, and in the constitution both therubber rollers motor 31. Moreover, when the packaging paper 20 (on anopening 20B side) is held between both therubber rollers packaging paper 20 is drawn from thepackaging paper roll 19. - Additionally, the
heat seal mechanism 27 is disposed between theguide roller 26 and the drawingroller 30. Theheat seal mechanism 27 for sealing theopening 20B of thepackaging paper 20 by thermal welding and dividing the paper for each dosage is constituted of a pair oftentative heaters main heaters tentative heater 28 andmain heater 29 include a not-shown operation apparatus, and are arbitrarily pressed onto or disconnected from the oppositetentative heater 28 andmain heater 29. Furthermore, when the respectivetentative heaters 28, andmain heaters 29 are energized, the heaters are heated at a predetermined temperature. - Moreover, the
main heaters vertical portions parallel portions parallel portion 29B has a width substantially equal to the width of thetentative heater 28, and thevertical portion 29A has a width double the width of theparallel portion 29B. Furthermore, when thepackaging paper 20 is held and heated by thetentative heaters 28 on opposite sides, thepackaging paper 20 is thermally welded from a foldedportion 20A side to substantially a middle portion between the folded portion and theopening 20B (a range shown by a solid line arrow of FIG. 7 is not thermally welded/fixed). - Furthermore, the
vertical portion 29A of themain heater 29 further holds and heats an upper portion above the portion heated and thermally welded by thetentative heaters 28 on opposite sides, and thermally welds and fixes thepackaging paper 20 from the foldedportion 20A side to theopening 20B, so that apouch 36A having theopening 20B on one side is formed on atentative heater 28 side. Additionally, theparallel portion 29B is constituted to thermally weld theopening 20B on the opposite side of the tentative heater 28 (a size between themain heater 29 and thetentative heater 28 in this case). - After the
packaging paper 20 is thermally welded by theheat seal mechanism 27, the paper moves by a predetermined distance on a drawingroller 30 side (in a direction of a hollow arrow of FIG. 7) by rotation of the drawingroller 30, that is, the portion thermally welded by thetentative heater 28 moves toward the main heater 29 (the thermally welded portion of themain heater 29 between the foldedportion 20A and theopening 20B). Subsequently, when themain heater 29 thermally welds thepackaging paper 20, thepouch 36A having theopening 20B is successively formed between thetentative heater 28 and thevertical portion 29A ofmain heater 29, and a thermally weldedpouch 36 excluding the foldedportion 20A is formed on the drawingroller 30 side. - Moreover, when the
main heater 29 thermally welds thepackaging paper 20 on thetentative heater 28 from the foldedportion 20A to theopening 20B, a plurality of perforation shapedholes 37 are cut/formed substantially in a center of the width of the thermally welded portion (between the foldedportion 20A and theopening 20B). Thereby, three sides (remaining one side being the foldedportion 20A) of thepackaging paper 20 are thermally welded, thepouch 36 having all peripheries sealed is formed, and thepouch 36 can be separated from a cut of the perforation shaped holes 37. - An operation procedure and action of the solid
preparation packaging apparatus 1 constituted as described above according to the present invention will next be described. First, thepackaging paper roll 19 is attached to therotation shaft 16. In this case, while therotation shaft 16 is inserted into theshaft member 21, thepackaging paper roll 19 is laid on thebase plate 17. In this case, the engagingportions 16A . . . of the base portion of therotation shaft 16 enters the engagedportions 21A . . . of the lower edge of theshaft member 21 immediately before thepackaging paper roll 19 abuts on thebase plate 17. - Subsequently, when the
packaging paper roll 19 is laid on thebase plate 17, the engagingportions 16A . . . of therotation shaft 16 are attachably/detachably joined into the engagedportions 21A . . . of theshaft member 21. Here, for thepackaging paper roll 19, as described above, thepackaging paper 20 is folded into two and wound around theshaft member 21, and has the foldedportion 20A andopening 20B. Therefore, if thepackaging paper roll 19 is attached upside down, the foldedportion 20A andopening 20B are reversed, and the solid preparation cannot be packaged in the solid preparation packaging mechanism. - Additionally, a user has heretofore sometimes attached the packaging paper roll upside down to the solid preparation packaging mechanism. This is because the upper and lower ends of the packaging paper roll cannot easily be distinguished. In this case, the user does not first notice a mistake until the wrongly attached packaging paper is drawn and attached to the solid preparation packaging mechanism.
- However, in the present embodiment, the engaged
portions 21A . . . of theshaft member 21 are formed only in the lower edge of the member. Therefore, even if the user attaches thepackaging paper roll 19 upside down, the engagingportion 16A does not engage with the engagedportion 21A, and the wrong attachment can be avoided. - After the
packaging paper roll 19 is attached to therotation shaft 16, thepackaging paper 20 of thepackaging paper roll 19 is drawn from the tip end thereof, successively passed outside therollers tension lever 23 and inside theguide roller 26, subsequently passed between thetentative heater 28 and main heater 29 (chute 13 is turned down), and drawn to the drawing roller 30 (FIG. 6). - Subsequently, the tip end of the
packaging paper 20 is inserted between both therubber rollers roller 30, and the drawingmotor 31 is driven. Then, therubber rollers packaging paper 20 is pulled toward the opposite side (forward side) from theheat seal mechanism 27 side. Therefore, thepackaging paper 20 is drawn by the drawingroller 30 and drawn forward. - Here, the
roller 25 of thetension lever 23 moves toward therotation shaft 16 when the tension of thepackaging paper 20 becomes strong, and moves apart from therotation shaft 16 when the tension becomes weak. Subsequently, the movement of theroller 25 is detected by the switch as described above. When the roller is detached from therotation shaft 16, the solenoid is driven by a not-shown controller, and thebrake 18 is pressed onto thebase plate 17. Subsequently, when theroller 25 moves toward therotation shaft 16, thebrake 18 is in turn disconnected. Thereby, an appropriate tension is constantly added to thepackaging paper 20 drawn from thepackaging paper roll 19. - When the
packaging paper roll 19 is attached to therotation shaft 16 in this manner, and the solidpreparation packaging apparatus 1 with the drawnpackaging paper 20 attached thereto is operated, a counted value indicating the number of drops of the solid preparation is reset. Moreover, thetentative heater 28 andmain heater 29 are heated at the predetermined temperature, and theturntable 10 is energized and constantly rotated. When an operator inputs prescription data into a not-shown input apparatus (personal computer, and the like) based on a doctor's prescription, the discharge drum of thetablet case 6 with the solid preparation contained therein is rotated/driven, and the type of solid preparation designated by the prescription data drops one by one onto theturntable 10. Moreover, the solid preparation also similarly drops onto theturntable 10 from thesub-container 7 in accordance with a user's arbitrary operation. - The number of solid preparations having dropped from the
tablet case 6 is counted by the not-shown controller based on a photosensor output. When the counted number of dropped solid preparations agrees with the number of solid preparations based on the prescription data, the rotation of the discharge drum is stopped, and the dropping of the solid preparation ends. The solid preparations (including the solid preparations from the sub-container 7) having dropped onto theturntable 10 are moved toward theoutside guide 11 and collected by a centrifugal force of therotating turntable 10, and drop into thechute 13 disposed below the discharge port D of theguide 11. Thereby, the solid preparation is passed through thechute 13 and introduced into thepouch 36A of thepackaging paper 20 positioned below the chute. - After the solid preparation is contained in the
pouch 36A of thepackaging paper 20 in this manner, the controller pulls thepackaging paper 20 by the drawingroller 30, and thermally welds and seals the pouch in theheat seal mechanism 27 as described above. - Here, a not-shown shutter for entering the
pouch 36A and expanding theopening 20B is attached to the lower end of thechute 13. In this case, thetentative heater 28 of theheat seal mechanism 27 thermally welds thepackaging paper 20 up to substantially the middle portion between the foldedportion 20A and theopening 20B of the paper, and the upper portion of the paper is not thermally welded. Therefore, thepackaging paper 20 can be drawn by the drawing roller 30 (in the direction of the arrow of FIG. 7) without lifting up the shutter of thechute 13. - Subsequently, when the
packaging paper 20 stops moving, thepackaging paper 20 is thermally welded again by themain heater 29, and the solid preparation is packaged into thepouch 36 and contained into thepouch 36A from theturntable 10 via thechute 13. This is repeated to automatically package a predetermined number of solid preparations of the type designated based on the prescription data. - With this drawing movement of the
packaging paper 20, theshaft member 21 ofpackaging paper roll 19 and therotation shaft 16 also rotate. Additionally, as described above, the engagedportions 21A . . . are formed in theshaft member 21 of thepackaging paper roll 19, and the engagingportions 16A . . . attachably/detachably engaging the engagedportions 21A . . . are formed in therotation shaft 16. Therefore, even when thebrake 18 for applying the tension to the paper abuts on thebase plate 17, the slip can firmly be prevented from occurring between therotation shaft 16 and theshaft member 21. - In this case, the spring member is not pressed onto the
shaft member 21 as in the conventional art. Therefore, theshaft member 21 can extremely easily be attached to/detached from therotation shaft 16, and the replacing operation of thepackaging paper roll 19 is not inhibited. Particularly, since the engagingportions 16A . . . are formed to project outside from the base portion of therotation shaft 16 disposed on the base 15 in the upright manner, and the engagedportions 21A . . . are notched/formed in the lower edge of the hollowtubular shaft member 21, the engagingportions 16A . . . engage with the engagedportions 21A . . . in a final stage of a series of operation for inserting therotation shaft 16 into theshaft member 21, and therefore attaching operability is further enhanced. - Moreover, since a plurality of engaging
portions 16A . . . and engagedportions 21A . . . are formed, an engaging relation of theshaft member 21 androtation shaft 16 is further strengthened, and slip can more firmly be prevented from occurring. - Additionally, in the present embodiment, the engaged
portions 21A . . . are formed by completely cutting the lower edge of theshaft member 21 of thepackaging paper roll 19 as shown in FIG. 5. However, as shown in FIG. 8, the engagedportions 21A . . . are formed such that the inner portion of the lower edge of theshaft member 21 is cut/removed, and the outer portion thereof remains uncut. Then, a disadvantage that the lower edge of theshaft member 21 is collapsed by a pressure during winding of thepackaging paper 20 can be prevented or inhibited. Additionally, in this case a projecting size of the engagingportion 16A of therotation shaft 16 is adjusted in accordance with a size of the engagedportion 21A. - Moreover, in the present embodiment the present invention is applied to the apparatus for collecting the solid preparation by the turntable, but the present invention is also effective for the apparatus for collecting the solid preparation by a belt conveyor, and the like.
- Possibility of Industrial Utilization
- As described above, according to the present invention, since an engaged portion is formed in a shaft member with a packaging paper wound therearound in a roll shape, an engaging portion formed on a rotation shaft of a solid preparation packaging apparatus with the shaft member attached thereto is attachably/detachably joined into the engaged portion, so that a slip between the rotation shaft and the shaft member can be prevented.
- In this case, since a spring member is not pressed onto the shaft member as in a conventional art, it is extremely easy to attach/detach the shaft member to/from the rotation shaft, and therefore a replacing operation of the packaging paper roll is not inhibited. Particularly, when the engaging portion is formed to project outside from a base portion of the rotation shaft disposed in an upright manner, and the engaged portion is notched/formed in an edge of the hollow tubular shaft member, the engaging portion engages with the engaged portion in a final stage of a series of operation for inserting the rotation shaft into the shaft member, and therefore attaching operability is further enhanced.
- Moreover, when a plurality of engaging and engaged portions are formed, an engaging relation of the shaft member and rotation shaft is further strengthened, and the slip can more firmly be prevented from occurring.
- Furthermore, when the notch is formed by cutting the edge of the shaft member to an outer portion from an inner portion of the edge, the shaft member is easily formed, and a rise of component cost can be minimized.
- Additionally, the notch is formed such that the inner portion of the shaft member edge is cut/removed and the outer portion thereof remains uncut. Then, a disadvantage that the edge of the shaft member is collapsed by a pressure during winding of the packaging paper can be prevented or inhibited.
