As shown in FIGS. 9 and 10, one end portion of the sheet 13 in the width direction is in contact with the outer peripheral side surfaces of the one first roller 59a and the one second roller 60a. The other end is held in contact with the outer peripheral side surfaces of the other first roller 59b and the other second roller 60b.
A method for attaching the seat 13 to the toilet apparatus 10 will be described later.

First, as shown in FIG. 1, the lid 35 is rotated upward to open the toilet seat 11 into a state where a person can be seated.
In this case, a lid switch 45 that is in contact with the surface of the toilet seat 11 when the lid 35 is closed is provided at the lower end of the back surface of the lid 35 and is controlled by the controller 114. Even when a human hand is accidentally inserted into the cylindrical body 12, when the lid portion 35 is open, that is, when the lid switch 45 is in an off state, The sheet supply unit 14 is controlled so as not to operate, and is configured to ensure the safety of the user.

Next, when the user sits on the toilet seat 11 as shown in FIG. 1 and excretes, the excrement and used paper fall from the opening 36 of the toilet seat 11, and FIG. The one end portion 29 is accommodated in the tubular sheet 13 that is welded via the inner peripheral surface of the tubular body 12 as shown in FIG.
Thereafter, when the user stands up from the toilet seat 11 and closes the lid 35 as shown in FIG. 1, the lid switch 45 is turned on to store the excrement A as shown in FIG. It moves to the state which can make the excrement storage bag 15 which was made.
Next, as shown in FIG. 1, the main power switch 42 provided on the rear part of the one side part 41 of the toilet body 38 is turned on, and then provided on the one side part 41 of the toilet body 38. The start switch 44 is pressed.

  When the start switch 44 as shown in FIG. 1 is pressed, as shown in FIGS. 5 and 9, one of the first rollers a holding the sheet 13 and one of the second rollers are sandwiched. When the other roller 60a and the other first roller 59b and the other second roller 60b rotate together, one end in the width direction of the sheet 13 becomes one first roller. 59a and one second roller 60a and the other end in the width direction are sandwiched between the other first roller 59b and the other second roller 60b and controlled by the control unit 114. The roller portion 17 holds both ends in the width direction of the sheet 13 and feeds them downward.

In this case, as shown in FIG. 9, the roller unit 17 is driven by the sheet supply unit 14, and the sheet supply unit 14 receives a command from the control board 117 when the start switch 44 is pressed. By driving the feed motor 49 and rotating the shaft 50 of the film feed motor 49, the motor gear 51 fixed to the tip of the shaft 50 is rotated.
As the motor gear 51 rotates, the drive gear 53 meshed with the motor gear 51 rotates, and the drive gear 53 rotates together with the drive shaft 52 to which the drive gear 53 is fixed.
Then, roller gears 54a and 54b fixed to both ends in the length direction of the drive shaft 52 rotate in conjunction with each other.
One roller gear 54a rotates in conjunction with a first transmission gear 55a meshed with the roller gear 54a and a second transmission gear 57a meshed with the first transmission gear 55a. When the first transmission gear 55a and the second transmission gear 57a rotate, one of the first rollers 59a is moved via the first roller shaft 56a to which the first transmission gear 55a is fixed. The second roller 60a rotates in conjunction with each other via the second roller shaft 58a to which the second transmission gear 57a is fixed.
Similarly, the other roller gear 54b rotates in conjunction with the first transmission gear 55b meshed with the low gear 54b and the second transmission gear 57b meshed with the first transmission gear 55b. When the first transmission gear 55b and the second transmission gear 57b rotate, one of the first rollers 59b passes through the first roller shaft 56b to which the first transmission gear 55b is fixed. Rotates in conjunction with each other, and one second roller 60b rotates in conjunction with the second roller shaft 58b to which the second transmission gear 57b is fixed.

Accordingly, the gears 51, 53, 54a, 54b, 55a, 55b, 57b, 57b and the shafts 50, 52, 56a, 56b, 58a, 58b are driven in conjunction with each other by driving the film feed motor 49. Thus, the one first roller 59a, the one second roller 60a, the other first roller 59b, and the other second roller 60b all rotate in conjunction with each other. The sheet 13 can be sent out in a stable state.
Also, since power transmission means by linking gears is adopted, there is less deterioration over time compared to the case where power transmission means using rubber rollers etc. are adopted, so maintenance work can be reduced. it can.

As shown in FIG. 3, the sheet 13 is formed with the opening 61 of the sheet 13 having a circumferential length of approximately 1020 mm, and the cylindrical body 12 is formed with a circumferential length of the upper end 31 of approximately 940 mm. And the peripheral length dimension of the lower end portion 28 is formed to be approximately 430 mm. Therefore, the sheet 13 disposed on the inner peripheral surface is radially increased toward the lower end portion 28 of the cylindrical body 12. Since the diameter of the lower end portion 28 of the cylindrical body 12 is reduced to approximately 137 mm, the excreta storage bag 15 having a width dimension l2 of approximately 137 mm as shown in FIG. 8 is created. be able to.
In this case, since the excrement storage bag 15 is created by being welded and melted by being reduced along the width direction of the sheet 13, as shown in FIG. 8, along the width direction of the sheet 13. Thus, a plurality of ridges D are formed.

As described above, since a plurality of ridges D are formed in the sheet 13 along the width direction, when the ridges of the sheet 13 are not uniformly formed, the sheet welding fusing portion 16 welds the sheet 13. Further, when performing the fusing, the thickness dimension of the sheet 13 may not be formed uniformly, and depending on the welded part, there is a possibility that the sheet 13 is not welded without being reliably welded.
In particular, when excrement enters the sheet 13 and the weight increases, the sheet 13 is pulled to both ends in the width direction of the sheet 13 sandwiched between the roller portions 17, and the width direction of the sheet 13 is increased. As a result, no wrinkles are formed in the central portion. As a result, the thickness dimension of the sheet 13 is thin in the portion where no wrinkles are formed, and the thickness dimension of the sheet 13 is not formed uniformly.
In order to eliminate such a situation, as shown in FIG. 7, the tubular body 12 is formed with a total of ten protrusions 125 for uniformly forming the plurality of flanges D.
Further, the ten protrusions 125 are formed in a straight line from the upper end 31 to the lower end 28 of the cylindrical body 12 and five along the radial direction B of the cylindrical body 12. They are formed so as to face each other.
Further, as shown in FIGS. 5 and 9, the roller portions 17 and 17 are configured by a pair of rollers 59 a and 60 a or 59 b and 60 b so as to be in sliding contact with each other in the rotation direction. 17 are arranged to face each other at a predetermined interval in the directions of the roller shafts 56a, 56b, 58a, and 58b, and the ten protrusions 125 of the cylindrical body 12 are arranged to face the roller parts 17 and 17 facing each other. It is arranged between.
Further, the cylindrical body 12 having the ten protrusions 125 has a pair of roller portions 17 and 17 as shown in FIG. 9 holding the widthwise ends of the sheet 13 and feeding the sheet 13. When the sheet 13 is disposed on the inner peripheral surface 30 of the cylindrical body 12 while the sheet 13 is held by the roller portion 17 in the width direction end portion thereof, the protruding portion 125 is formed. Are arranged so as to be arranged at positions that do not overlap with the roller portions 17 and 17 in the vertical direction. Has been.
Therefore, as shown in FIGS. 5 and 9, the roller portions 17 and 17 are configured by a pair of rollers 59 a and 60 a or 59 b and 60 b so as to be in sliding contact with each other in the rotation direction. 17 are arranged to face each other at a predetermined interval in the directions of the roller shafts 56a, 56b, 58a, 58b, and the plurality of protrusions 125 of the cylindrical body 12 are arranged on the roller parts 17, 17 facing each other. When the sheet is pulled downward by the roller parts 17 and 17 as in the prior art, a wrinkle is formed only at the part where the sheet 13 is pulled into the roller parts 17 and 17, and the roller The occurrence of wrinkles is small at portions other than the portions 17 and 17, and the situation in which wrinkles are not formed uniformly along the width direction of the sheet 13 can be eliminated. While maintaining a substantially equal state of the formed wrinkles on the sheet 13 is sent along the inner circumferential surface 30 of the tubular body 12.
Then, when the sheet is pulled downward by the pair of roller portions as in the prior art, the sheet 13 is pulled into the pair of roller portions 17 and 17 to be pulled into the rollers 59a and 60a or 59b and 60b. The wrinkles are shifted to only the portions, and the portions of the sheet 13 disposed between the pair of roller portions 17 and 17 are not wrinkled. Thus, it is possible to eliminate a situation in which a thick portion and a thin portion can be formed, and leakage may occur in the thin portion when the excrement is stored.
That is, even when the sheet 13 is pulled downward by the roller portions 17, 17, the plurality of protrusions 125 are formed at a portion between the portions of the sheet 13 drawn by the pair of roller portions 17, 17. Since wrinkles are formed, the sheet 13 is sent out along the inner peripheral surface 30 of the cylindrical body 12 while maintaining the uniform state of the wrinkles formed in the sheet 13, so that the sheet when being welded Since the wrinkles can be generated substantially uniformly in the width direction of the sheet 13 and the thickness of the sheet 13 including the wrinkles can be formed substantially uniformly, the sheet welding fusing part 16 can further weld and cut the sheet 13. Since the excrement storage bag 15 that can be surely performed and the sealing property is ensured can be created, it is possible to reliably prevent the excretion from leaking out of the excrement storage bag 15. Kill.

Further, when the sheet 13 is delivered, there is a possibility that the reduced sheet 13 is expanded again and caught in a gear or the like.
In order to prevent the sheet 13 from being caught in a gear or the like, as shown in FIG. 9, one of the entanglement prevention plates 27a is in contact with the one first roller 59a and the one second roller 60a. Between the one first transmission gear 55a and the one second transmission gear 57a, and from the holding plate 46 to the one first transmission gear 55a and one second transmission gear 57a. The transmission gear 57a has a predetermined height dimension capable of guarding the meshing portion and is erected downward. Similarly, the entanglement prevention plate 27b includes the one first roller 59b. Between the contact portion with one second roller 60b and the meshing portion between the one first transmission gear 55b and one second transmission gear 57b, from the holding plate 46 to the above-mentioned One first transmission gear 55b and one second transmission gear 55b It is erected downward with a predetermined height dimension which can guard the meshing portion between the transmission gear 57 b.
Accordingly, even when the sheet supply unit 14 is operated, the movement of the sheet 13 in the width direction is restricted, and both end portions in the width direction of the sheet 13 are connected to the first transmission gear 55a and the one of the first transmission gear 55a. It is possible to prevent the second transmission gear 57a and the other first transmission gear 55b and the other second transmission gear 57b from being caught.

  In this case, as shown in FIG. 9, the entanglement prevention plates 27a and 27b are arranged to face each other, and the distance dimension between one entanglement prevention plate 27a and the other entanglement prevention plate 27b is approximately 140 mm. Therefore, the width direction dimension of the excrement storage bag 15 can be regulated to about 140 mm.

Then, as shown in FIG. 9, the sheet 13 sent out by the roller unit 17 stops at a predetermined position under the control of the control unit 114.
Thereafter, the drive unit 20 drives the slide bar 64 a and the slide bar 64 b to slide toward the center in the length direction of the holding plate 46.
Here, the drive unit 20 operates by driving the slide bar drive motor 65, and the slide bar drive motor 65 rotates the drive shaft 67 of the slide bar drive motor 65, whereby the drive shaft. The motor gear 68 fixed to the tip of 67 is rotated.
When the motor gear 68 is rotated, the drive gear 69 engaged with the motor gear 68 is rotated together with the drive shaft 70 fixed to the drive gear 69, and both end portions in the length direction of the drive gear 70 are rotated. Rotating wheels 71a and 71b fixed to each other rotate in conjunction with each other.

  As shown in FIG. 10, the rotating wheels 71a and 71b and the slide bars 64a and 64b include short arms 72a and 72b and long arms 73a and 73b that can convert the rotating operation of the rotating wheels 71a and 71b into a linear operation. Is attached so as to be rotatable, and the slide bar 64a, 64b is driven in conjunction with the drive of the slide bar drive motor 65, so that the slide bar with respect to the central portion in the length direction of the holding plate 46 is provided. Since the slide bar 64a and the slide bar 64b can slide and press the pressing member 21 against the heat seal terminal portion 18 while holding the positional relationship of 64a and 64b evenly, the pressing member is pressed against the heat seal terminal portion 18. 21 can be stably pressed.

As shown in FIGS. 9 and 10, the pressing pieces 80 a and the pressing pieces of the sheet pressing portion 25 located on the center side in the length direction of the holding plate 46 by the sliding operation of the slide bars 64 a and 64 b. 80 b is pressed against the urging force of the coil springs 81 a, 81 a, 81 b, 81 at the center in the length direction of the holding plate 46 via the sheet 13, so that the lower part of the sheet welding fusing part 16 The sheet 13 is held.
As a result, the wrinkles of the sheet 13 formed by being reduced in the radial direction can be held in a uniform state, and the weight of the excrement A stored in the sheet 13 is added to the sheet 13. Since it is possible to prevent the sheet 13 from being welded and cut, it is possible to create the excreta storage bag 15 having a tight seal by performing the welding and cutting of the sheet 13 more reliably.
Further, since a sheet pressing rubber (not shown) is fixed to the surfaces of the pressing piece portions 80a and 80b, slipping when the sheet 13 is held is prevented and the holding of the sheet 13 is stabilized. Can be done.

Thereafter, as shown in FIGS. 11 and 12, the pressing member 21 is pressed against the heat seal terminal portion 18 by the sliding operation of the slide bars 64a and 64b, and the sheet 13 is held as shown in FIG. The
Further, as shown in FIG. 13, there is provided a pressing force adjusting portion 85 that can alleviate the impact generated when the pressing member 21 is pressed against the heat seal terminal portion 18 and can maintain the holding state of the sheet 13. In the pressing force adjusting portion 85, coil springs 26a and 26b as urging members inserted through the insertion pipes 88 and 88 urge the pressure washers 89 and 89 and the step surfaces 96 and 96 of the mounting hole 86, respectively. The rod shaft portions 87 and 87 having the head portions 91 and 91 having the head portions 91 and 91 fixed by the nuts 90 and 90 are inserted into the mounting holes 86 and 86 and the insertion tubes 88 and 88, respectively. Therefore, the slide bar 64a is retracted against the urging force of the coil springs 26a and 26b as the urging members, and the impact caused by the mechanical load on the drive unit 20 during the press contact is reduced. It can also be.
Further, at the time of the pressure contact, the slurd bar 64a moves so as to retreat relative to the rod shaft portions 87, 87. Therefore, after the contact, the heat seal terminal is applied by the biasing force of the coil springs 26a, 26b as biasing members. It advances so that the part 18 and the said press member 21 can press-contact favorably.
As a result, the pressed state can be maintained and the held state of the sheet 13 can be maintained, so that the force applied to the sheet 13 acting in the thickness direction of the sheet 13 at the time of press contact can be alleviated and the sheet 13 is welded It is possible to avoid the situation of breakage and to maintain the pressure contact state.

Then, as shown in FIG. 5, the sheet 13 can be welded and melted while being held by the sheet pressing portion 25 below the sheet welding fused portion 16, so that the sheet 13 is welded by the sheet welding fused portion 16. And the excrement storage bag 15 with which airtightness was ensured can be created by performing a fusing more reliably.
Further, as shown in FIGS. 6A to 6C, when the sheet 13 is welded and cut, the heat seal is held in a state where the sheet 13 is sandwiched between the heat seal terminal portion 18 and the pressing member 21. This is done by supplying power to the terminal section 18.
First, by supplying a current of 25 A with a DC voltage of 10 V to the heat seal terminal portion 18 of the sheet welding fusing portion 16 for about 1.5 seconds and setting the heater temperature to about 115 degrees, the resin-made above-mentioned The sheet 13 is melted into a liquid state.
In this case, as shown in FIG. 6A, the heat seal terminal portion 18 includes a substrate portion 18a and a substrate protrusion 22 along the length direction at a substantially central portion in the width direction of the substrate portion 18a. And is bent in the direction of the anti-substrate protruding portion 22 at both ends in the width direction of the substrate portion 18a, so that it extends from the substantially central portion in the width direction of the substrate portion 18a to the end portion in the width direction. Thus, an inclined surface 22a that is gently inclined in the direction of the anti-substrate protrusion 22 is formed, and is housed and fixed in a groove 63 formed by the walls 23 and 23 of the base 19, and the inner side of the walls 23 and 23 The inner end portions in the thickness direction of the inner side surface portions 23a, 23a of the groove portion 63 forming the wall portion are in contact with both end portions in the width direction of the heat seal terminal portion 18, and in the groove portion 63 of the base portion 19. When the heat seal terminal 18 is stored and fixed, The wall 23, 23 of the base 19 has a thickness dimension smaller than the height of the substrate protrusion 22 of the heat seal terminal 18, and as shown in FIG. 6 (b), the sheet seal terminal The portion 18 is fixed in the groove portion 63 so that the substrate protrusion 22 can protrude outward in the thickness direction from the thickness direction-side surface, and the heat seal terminal portion 18 is fixed to the groove portion 63. Since the gaps 24 and 24 are formed between the opposing inner side surface parts 23a and 23a of the groove part 63 and the width direction both ends of the board part 18a, respectively, when stored and fixed inside. In the state where the sheet 13 as shown in FIG. 6B is sandwiched between the heat seal terminal portion 18 and the pressing member 21, a current of 25 A is applied to the heat seal terminal portion 18 at a DC voltage of 10V. Supply for seconds And by, the sheet 13 flows into the gap portion 24 by melting the liquid.

Then, the power supply is shut off in a state where the pressing member 21 is pressed against the heat seal terminal portion 18, and the molten liquid sheet resin is solidified by natural cooling for about 40 seconds.
In this case, between the gaps 24 and 24 and the pressing member 21, the liquid sheet resin of the sheet 13 melted in the sheet 13 stays in the gaps 24 and 24 and solidifies. In the sheet 13, weld wall portions 124, 124 are formed at portions where the sheet 13 is welded.
Further, the thick portion and the thin portion of the sheet 13 formed by the wrinkles of the sheet 13 generated by reducing in the radial direction can be made uniform, and the liquid staying in the gap portion 24 can be obtained. When the sheet resin is solidified, as shown in FIG. 6C, the weld wall portions 124 are formed.
Thereafter, the pressing state of the heat seal terminal portion 18 and the pressing member 21 is released, and the heat sealing terminal portion 18 and the pressing member 21 are separated by the operation of the driving unit 20.

As a result, as shown in FIGS. 6B and 6C, the weld wall portions 124 are formed on the sheet 13, and the welding end portions of the sheet 13 are reliably welded. Since the excrement storage bag 15 having a sealed property as shown in FIG. 5 can be created, the excrement leakage from the excrement storage bag 15 can be reliably prevented.
In addition, the portion of the sheet welded and fused portion 16 that contacts the sheet 13 is processed with fluororesin, and the sheet welded and fused after the fusion without melting the welded portion melted at a high temperature when the sheet 13 is welded. Since it is easy to leave | separate from the part 16, the cutting | disconnection of the sheet | seat 13 can be performed more reliably and the excrement storage bag 15 with which airtightness was ensured can be created. As a result, it is possible to eliminate the entanglement of the welded portion of the sheet 13 at the time of welding to the welded cut portion 16 and incomplete welding resulting from difficulty in separation, and it is possible to reliably form a sealed welded portion. Therefore, it is possible to reliably prevent the excrement A from leaking out of the excrement storage bag 15.
Also, conventionally, as shown in FIG. 16, a tape 211 treated with a fluororesin was attached to eliminate the entanglement or difficulty of detachment of the sheet welded portion to the heat seal terminal portion 207. In the toilet apparatus 10 according to the invention, since the fluorocarbon resin processing is applied to the contact portion of the sheet welded and fused portion 16 with the sheet 13, it is not necessary to replace the tape 13 and the conventional fluorocarbon resin processing Compared to the case where the tape 211 having a high consumption frequency that requires replacement and is used for the heat seal terminal portion 207, the toilet device 10 that can reduce maintenance work can be provided.
Further, the sealing means of the sheet welding cut portion 16 is generally called impulse sealing means. This impulse sealing means is a method in which the sheet 13 is melted and welded by instantaneously supplying a large current to generate heat in the heat seal terminal portion 18, so that the sheet is only energized for a short time only during welding. Since 13 can be welded, power consumption can be reduced as a whole.

Here, a technical difference between the related art and the toilet apparatus 10 according to the present invention will be compared.
In this type of conventional toilet apparatus generally sold in the market, as shown in FIG. 16, the sheet welding fusing part 212 has a heat seal terminal part 207 disposed and fixed along the width direction of the sheet 211. And a plate-shaped pressing member 208 that is disposed to face the heat seal terminal portion 207 and can be pressed against the heat seal terminal portion 207 by a driving member. The heat seal terminal portion 207 is a base member. The heat seal terminal portion 207 is fixed to the material 209 and covered with a tape 210 that has been subjected to fluororesin processing.
When fusing the sheet 211 using the sheet welding fusing part 206, the pressure member 208 is pressed against the heat seal terminal part 207 via the tape 210, and the sheet 211 is energized by energizing the heat seal terminal part 207. A storage bag having a predetermined length dimension was created by fusing along the width direction and fusing both ends in the length direction.
In this case, the fluororesin-processed tape 210 fixed on the heat seal terminal portion 207 prevents the heat seal terminal portion 207 and the sheet 211 from sticking at the time of fusing and welding. It is used to improve the distance between the sheet 211 and the sheet 211.
However, when the tape 210 processed with fluororesin is applied to the heat seal terminal portion 207, heat is transmitted through the tape 210 when the sheet 211 is fused and welded. As a result, the sheet 211 may adhere to the heat seal terminal portion 207 when the sheet 211 is melted, and the fusing performance is not good.
Further, since the heat seal terminal portion 207 is covered with the tape 210 which has been subjected to fluororesin processing, the tape 210 is easily damaged when the number of times of fusing and welding the sheet 211 is increased. When the tape 210 is damaged frequently, it is necessary to replace the tape 210. As a result, the frequency of replacement of the tape 210 increases, and the maintenance frequency increases. .
However, as shown in FIG. 6, in the toilet apparatus 10 according to the present invention, the heat seal terminal portion 18 is subjected to fluororesin processing, so that the separation from the sheet 13 at the time of fusing is possible. It is good and does not require tape replacement. Compared to the conventional case where a tape with high wear frequency that requires replacement with fluororesin processing is used for the sheet welding fusing portion 16. Maintenance work can be reduced.

  Further, as shown in FIG. 6, the pressing member 21 is formed of a heat-resistant elastic resin material, and the pressure contact state between the heat seal terminal portion 18 and the pressing member 21 becomes good, and the sheet 13 is welded and Since fusing can be performed more reliably and the excrement storage bag 15 with which sealing property was ensured can be created, the excretion leaking from the excrement storage bag 15 can be prevented reliably.

  Then, as shown in FIG. 5, the excreta storage bag 15 created by fusing the sheet 13 after welding is placed on the drawer 34 disposed below the toilet body 38 as shown in FIG. When the excrement storage bag 15 is to be discarded, the drawer 34 disposed below the toilet body 38 is pulled out from the back side of the toilet apparatus 10 and stored in a predetermined amount. The said excrement storage bag 15 accommodated in the drawer | drawing-out part 34 can be taken out, and can be discarded suitably.

Here, a method of mounting the seat 13 on the toilet device 10 will be described.
Since the sheet 13 is formed to have a length dimension of about 15 m, it is not necessary to replenish the sheet 14 each time. However, since the sheet 13 is a consumable item, when it is used up or used for the first time. Therefore, it is necessary to attach the seat 13 to the toilet device 10.
When the seat 13 is attached to the toilet apparatus 10, first, as shown in FIGS. 3 and 5, the sheet 13 is opened at one end portion 29 of the tubular body 12 and the opening of the tubular body 12. As shown in FIG. 5, it is arranged along the inner peripheral surface 30 of the cylindrical body 12 by being inserted through the portion 48, and is folded outward at the upper end portion 31 of the cylindrical body 12. It arrange | positions along the outer peripheral surface 32 of the shape body 12, and it folds.
Then, as shown in FIG. 5, the sheet 13 can be sent out by attaching both end portions in the width direction of the sheet 13 to the roller portion 17, but one of the roller portions 17 as shown in FIG. The first roller 59a and one second roller 60a are in contact with each other, and the other first roller 59b and the other second roller 60b are in contact with each other. It is necessary to release the contact state.
In this case, the lever portion 100 as shown in FIG. 4 is slid into the slide groove hole 101 and is engaged with the engagement groove 120, so that the contact state of the roller portion 17 is released by the release portion 33.
Specifically, as shown in FIG. 9, by the sliding operation of the lever portion 100, the operation arm 102 is rotated about the support shaft portion 103 as a support shaft, and the slide shaft portion is driven by the locking plate 106 of the operation arm 102. The second roller 60a, 60b is separated from the first roller 59a, 59b by locking 104 and sliding the slide shaft portion 104 and the second roller shaft 58a, 58b together.
As shown in FIG. 9, one first roller 59a and one second roller 60a are in contact with each other, and the other first roller 59b and the other second roller 60b. Are in contact with each other, the second rollers 60a and 60b are separated from the first rollers 59a and 59b.
Then, after arranging the both ends of the sheet 13 in the width direction so as to be sandwiched between the roller parts 17, the separated second rollers 60 a and 60 b are moved through the sheet 13 to the first rollers 59 a and 59 a. The both ends of the sheet 14 in the width direction are sandwiched between the roller portions 17 by being brought into contact with 59b.
