Abstract

PURPOSE:To check the occurrence of surface-out deformation in each of paper sheets being deteriorated in rigidity as well as to prevent an abnormal fold from occurring, by setting up a friction member, being high in a friction factor so as to make it contact with paper sheets, at the opposite paper sheets delivering side of a separatory delivery device. CONSTITUTION:At the time of separating motion, a guide roller 39 advances on the top of a bill B synchronously with a pickup roller 34. Therefore, deformation due to a pushing-out phenomenon in the bill to the opposite paper sheets delivering side is regulated by the guide roller 39 so that an attitude of the bill is kept constant, whereby interference with a guide member or the like on an upper part of the bill is reducible and also conveying resistance is made smaller. In addition, a friction member including rubber or the like is installed on the circumference of the guide roller 39. In consequence, friction resisting force 107 to be produced by the said friction member acts against an orthogonal direction with a bill delivering direction, namely, a direction of trying to bring the bill nearer to the center within the surface. With this friction resisting force 107 acting in proper, the occurrence of a Z-shaped overlapped fold at the central part is preventable.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a paper sheet delivery device that separates and sends out a large number of stored paper sheets one by one.

[Background of the invention]

The conventional paper sheet handling device is 1, for example, Japanese Patent Application Laid-Open No. 59-10
As disclosed in Japanese Patent No. 2730, a feeding means for feeding paper sheets accumulated in a storage section, a feeding means for feeding paper sheets, and a feeding means disposed opposite thereto to impart frictional resistance to the paper sheets. It has separation means to

In such a device, when a large number of paper sheets, such as banknotes, are piled up, the group of banknotes swells due to folds and wrinkles in the banknotes, and if the strength of the banknotes is particularly reduced due to folds in the center, the banknote feeding operation may be delayed. As the separation and feeding operation progresses, the center of the banknote rises into a large mountain shape.
There is a problem in that the sent-out banknotes have a strong 7-shaped fold in the center. This phenomenon will be explained in detail using FIG.

FIG. 8(a) shows group B of banknotes stacked in large numbers and the feeding means 34 that comes into contact with them. The relationship between the deformation regulating means 39 and various forces 100 to 103 acting on the banknote is shown.

That is, a large number of banknotes B group are accumulated, and
When pressed against it, its center deforms into a concave shape. When the feeding means 34 rotates in this state, a conveying force of 100 acts on the banknote B in the banknote feeding direction. on the other hand,
Although not shown, a feeding means and a separating means are provided downstream of the feeding means 34, and apply a resistance force 101 to the banknotes B being fed. In addition, there is a resistance force from the banknote guide located on the top and front surface of the banknote B]01. Furthermore, if a guide roller 39 is provided as a deformation regulating means for regulating the deformation of the upper surface of the banknote, this also reduces the resistance force 103.
A frictional resistance force is also generated between the lowest banknote and the banknote on the lower surface, but this is not shown. Since the electrical transmission force 100 by the feeding means 34 acts on the center of the banknote B, these resistance forces generate component forces in the direction of moving both sides of the banknote toward the center.

As a result, as shown in FIG. 8(b), the banknote B has a convex deformation portion 104 in which the central portion is deformed into an upwardly convex shape.

At this time, if the banknote B is new and has no bends and high rigidity, the banknote B will not buckle. However, if the rigidity of the central part of the banknote is low due to folds etc.
) As shown in FIG. 8(b), the convex deformed portion 104 is a bent portion 105 that buckles and breaks as shown in FIG. 8(c).
occurs. When the movement of one banknote further progresses and the central folded part 105 is pinched and suppressed by a conveyor belt, rollers, etc., a 7-shaped overlapped folded part 10 is formed as shown in FIG. 8(d).
6 will occur strongly.

In particular, in banknote handling devices that recycle deposited banknotes and use them as payout banknotes, there are many banknotes with a high circulation rate, that is, flexible banknotes with many folds and wrinkles.
The above folding occurs frequently.

When a banknote with such folded folds is used as a payout banknote by a banknote handling device, the banknote cannot be recognized by a discrimination unit in the device and is rejected.

In addition, misjudgment may occur in some cases. If the rejection frequency increases, this will lead to problems such as a decrease in the amount of bills to be paid out, a decrease in the operating rate of the device, and a decrease in fund management efficiency. Furthermore, when misjudgment occurs, the reliability of the device decreases.

[Purpose of the invention]

An object of the present invention is to provide a paper sheet delivery device that suppresses out-of-plane deformation of paper sheets with reduced rigidity and prevents abnormal folding.

[Summary of the invention]

A feature of the present invention is that a friction member with a high friction coefficient is disposed on the paper sheet delivery side of the separating and feeding means so as to come into contact with the filter paper sheets fed out by the feeding device, and the filter paper is fed out and separated by this friction member. A force is applied within the plane of the leaf toward the center of the sheet to resist the force that tends to move and deform both sides of the sheet, thereby preventing folds that tend to occur in the center of the sheet. It is characterized by preventing.

0 and safe 11.

Also, according to the customer's request, the first denomination box 9 and the second denomination box 9
The banknotes B stored in the denomination box 10 can be paid out to the deposit/withdrawal port 2 through the front/back reversing mechanism 7 with their surfaces aligned.

Next, the configuration of the impeller stacker section and separation mechanism described above will be explained using FIGS. 2 to 5.

In these figures, two feed rollers 20 are provided on a shaft 23 rotatably supported by a frame 22 and have a friction member 21 on a part of the circumference thereof. On both sides of the two feed rollers 20, stopper rollers 24 are disposed coaxially with the shaft 23, as shown in FIGS. 2 and 3. The stopper roller 24 is made of a material with a low coefficient of friction, such as metal. The foot roller 20 and the stopper roller 24 each have a groove 2OA in the circumferential direction.

It has 24A. A gate roller 25 made of a friction member is disposed so as to fit into these grooves 2OA and 24A. That is, the feed roller 20 and the gate roller 25, and the stopper roller 24 and the gate roller 25 are arranged to overlap each other.

On the other hand, a timing pulley 26 is attached to one end of the shaft 23. This pulley 26 has a timing belt 2
It is multiplied by 7. This belt 27 is connected to a motor (not shown).

As a result, the rotation of the shaft 23, that is, the feed roller 2° is controlled. A gear 28 is fixed to a portion of the shaft 23 between the feed rollers 20 and 20.

This gear 28 engages with a gear 30 that is rotatably mounted on an arm 29 that is swingably mounted around the shaft 23. A cam 31 is attached coaxially to the side of the gear 30 and rotates together with the gear 30. Further, the free rotation shaft 32 attached to one end of the arm 29 has the cam 3
A rubber roller 33 and a pickup roller 34, which serves as a means for separating and feeding out banknotes and are made of rubber with a high friction coefficient and are used to apply conveying force to the banknotes, are fixed to the positions where they engage with the banknotes. In this embodiment, the pickup roller 34 is arranged so as to sandwich the rubber roller 33 so as to come into contact with the center in the longitudinal direction of the upper surface of the stacked banknotes when separating and feeding out the banknotes.
Individually arranged. When the gear 28 rotates once, the cam 31 contacts the rubber roller 33 by a predetermined rotation angle and rotates the pickup roller 34. That is, cam 3
1, when the shaft 23 rotates, the feed roller 2o and the pickup roller 34 are driven in synchronization. A guide roller 39 serving as paper sheet deformation regulating means is disposed on the arm portion 29a of the arm 29 so as to be freely rotatable. A friction member 74 made of rubber or the like is disposed on the outer periphery of the guide roller 39. The guide roller 39 is located in the anti-banknote sending direction with respect to the pickup roller 34 described above, and is arranged so as to contact the banknote surface at a position approximately equal to or higher than the surface where the pickup roller 34 and the banknote contact. There is. Normally, when a large number of banknotes are accumulated, the banknotes swell due to folds and wrinkles, so
For example, when banknotes are stacked horizontally, it is difficult to maintain a constant posture of the banknotes. Therefore, the pickup roller 3
4 comes into contact with the group of banknotes on the banknote sending side, since the banknote sending side of the banknote group is free, this part lifts up and the upper part of the banknote group tends to tilt forward toward the banknote sending side. This guide roller 39 functions to prevent the banknote group from tilting forward in the banknote delivery direction due to its bulging effect when the pickup roller 34 comes into pressure contact with the banknote delivery side of the stacked banknote group. Maintain a stable posture.

FIG. 6 shows the working relationship of forces corresponding to FIG. 8. As described above, in this embodiment, a friction member 74 made of rubber or the like is disposed around the outer periphery of the guide roller 39 serving as a banknote deformation regulating means. Although this guide roller 39 acts only a slight resistance force 103 in the banknote feeding direction, it acts as a friction member in a direction perpendicular to the banknote feeding direction, that is, in a direction in which the banknote B is shifted to the center within its plane. 7
A frictional resistance force 107 generated by 4 acts.

The friction coefficient of the friction member 74 and the height of the guide roller 39 are adjusted so that this frictional resistance force 107 has an appropriate value.

By selecting the number of two pieces to be arranged, it is possible to prevent the occurrence of overlapping folds in the Z-shape at the center.

The swinging position of the pickup roller 34 is obtained by detecting the amount of movement of the other end of the arm 29, which is swingably attached to the shaft 23, using the sensor 41. This sensor 40
The output is applied through a control circuit 41 to a drive motor 42 of a banknote pressing means, which will be described later.

Pick-up roller 34 is coupled to a spring 44 that biases pick-up roller 34 to rotate counterclockwise. Then, this spring 44 is activated by the safe 1.
1. When the arm 2 is brought into pressure contact with the banknotes B stored and accumulated in the storage section such as the denomination box 9 and 10, and the banknote suppressing means described later is activated to push the banknote B upward.
The upper limit position is regulated by a stopper 43 that comes into contact with 9. Further, the arm 29 equipped with the pickup roller 34 and the like is moved onto or above the stacked banknotes in the storage section by a cam 45 rotated by another driving means and a roller 46 that engages with the cam 45. Further, a stopper 47 that also functions to hold down the stacked banknotes supported by the frame 22 is connected to the arm 29 by a link 48 . Therefore, the stopper 47 rotates as the arm 29 swings. It goes without saying that the pressing force on the banknote B may be applied by using its own weight instead of the spring 44.

In the vicinity of the feed roller 20 and gate roller 25 described above, a banknote push-back arm 49 is provided to return the banknote B caught between the feed roller 20 and gate roller 25 to the storage section at the end of banknote feeding. ing. This arm 49 is attached to a rotatable shaft 50. The shaft 50 is rotated by the driving means, and the rotation operation is performed from the position shown in FIG.
Swing to the position shown in the figure. Due to the swinging of this shaft 50,
The arm 49 pushes the bill B back into the storage section.

A shaft 51 parallel to the shaft 23 is rotatably supported on the frame 22 . This shaft 51 is driven by a motor (not shown). An arm 52 is arranged symmetrically on this shaft 51.
It is rotatably supported. A cantilever-supported shaft 53 is provided at the tip of the arm 52 . An impeller 54 serving as a means for receiving one banknote is rotatably attached to this shaft 53. This impeller 54 includes a gear 55 fixed to the shaft 51, an intermediate gear 56 provided on the arm 52, and the impeller 54.
It is rotated by meshing with a gear 57 that is integrally attached.

On the circumference of the impeller 54, there are blades 5 for receiving a plurality of banknotes.
4A are attached at equal intervals, and the banknotes B sent out from a transport path (not shown) can be held and transported by rollers 58 and 59 and pushed between the blades 54A of the impeller 54. Also,
Since the arm 52 is rotatable with respect to the shaft 51, the impeller 54 can swing in the same manner as the pickup roller 34 and the guide roller 39. The movement of the arm 52, that is, the movement of the impeller 54, is detected by a sensor 60 provided opposite the end of the arm 52. The signal from this sensor 60 is used to control the amount of descent of the banknote suppressing means, which will be described later, in accordance with the amount of banknotes B accumulated. That is, as shown in FIG. 5, as the conveyed banknote B received by the impeller 54 is held by one impeller 54 and rotates, it is fed into the storage section, and when it comes into contact with the stopper 47, the banknote B is stopped by the impeller 54. He was forced to leave the 54.

As a result, the banknotes B are sequentially accumulated in the storage section. When the banknotes B are accumulated to a certain extent, the impeller 54 is pushed upward by the accumulated banknotes B, and when it rises to a specified position, the rise of the impeller 54 is detected by the sensor 60. The signal from this sensor 60 is transmitted to the control circuit 6
1 is applied to a drive motor 42 of a banknote suppressing means, which will be described later, to lower the stacked banknotes. As a result, the impeller 5
4 is controlled so that it always oscillates within a substantially constant range.

Next, the configuration of the bill pressing means described above is shown in FIGS. 4 and 5.
This will be explained using figures. The push plate 62 receives and receives banknotes B accumulated in the storage section.

The push plate 62 is supported by a guide shaft 63 and a screw shaft 64 provided on the frame 22, and is driven in the vertical direction. That is, the rotation of the drive motor 42 is caused by the rotation of the belt 65.
When the signal is transmitted to the screw shaft 64 by
4 rotates forward and backward, the push plate 62 is moved up and down via a nut 66 that engages with this screw shaft 64. At this time, when the pickup roller 34 separates the bills B, the sensor 40 is activated by the swinging of the arm 29 to control the positions of the pickup roller 34 and the guide roller 39. In other words, the positions of the pickup roller 34 and the guide roller 39 are closer to the feed roller 20.
And the height of the push plate 62 is controlled so that it is at an appropriate position relative to the gate roller 25. Similarly, when stacking banknotes B as shown in FIG. When B is accumulated and the impeller 54 is pushed upward, the push plate 62 is lowered to correct the position of the impeller 54 downward. As a result, the height of the impeller 54 is controlled within a certain range with reference to the position of the stopper 67 that determines its lower limit point.

That is, the force with which the impeller 54 is pushed up by the stacked banknotes B, or conversely, the pressing force with which the banknotes B are pressed by the impeller 54 can be kept constant.

Next, the operation of the above-mentioned cash handling section will be explained.

First, the operation of dispensing the banknotes accumulated in the storage section will be explained using FIG. 4.

When separating and sending out the banknotes B accumulated in the storage section, the arm 29 is moved by the cam 45 and the roller 46.

It is set in a substantially horizontal state as shown in FIG. At this time, the guide roller 39 at the end of the arm 29 comes into contact with the side opposite to separation and delivery of the banknote B in the uppermost row of the stacked banknote group.
Reduce the rise of this part.

In this state, the drive motor 42 is driven and the drive belt 65 is
The screw shaft 64 is rotated through.

As the screw shaft 64 rotates, the push plate 62 rises, and the banknotes B in the storage section are gradually pressed against the pickup roller 34 and the guide roller 39. The push plate 62 further rises, and the stacked banknotes B overcome the spring 44 and lift the pickup roller 34 and the guide roller 39. When the pickup roller 34 and the guide roller 39 rise to the position set by the sensor 40, the sensor 4o detects that position and stops the rotation of the drive motor 42. By stopping the drive motor 42, the lifting of the push plate 62 is stopped.

Thereby, one banknote amount is set in a separable state.

Next, when the feed roller 20 is rotated, the power from the gear 28 fixed to the shaft 23 is transmitted to the cam 31, and the rotation of the cam 31 causes the pickup roller 34 to rotate intermittently in synchronization with the feed roller 20. do. As a result, the uppermost banknote B pressed against the pickup roller 34 is sent to the separating section constituted by the feed roller 20 and the gate roller 25. At this time, when a plurality of banknotes B are fed into the separating section at the same time, the banknotes B are separated one by one by the frictional resistance of the gate roller 25 and sent out downstream.

On the other hand, the guide roller 39 rotates due to the frictional force of contact with the banknote B that occurs when the banknote B is fed out, and rolls into contact with the banknote B.

The separation of banknotes B progresses, and the pickup roller 34 and push plate 6
When the amount of banknotes between 2 and 2 decreases, the pickup roller 3
4 and the guide roller 39 are moved by the arm 29 li! ! 1
23, the arm 29 with the pick-up roller 34 and the guide roller 39 also rotates counterclockwise. Therefore, when the signal from the sensor 40 disappears, the drive motor 42 operates again to push up the push plate 62 and press the bill B against the pickup roller 34 and guide roller 39 in the same manner as described above.

As described above, the pickup roller 34 can press the banknote B with a constant force, and can always keep its operating height within a constant range with respect to the separating section composed of the feed roller 20 and the gate roller 25. Therefore, the banknotes B can be separated stably at all times without the occurrence of misfeed.

Next, at the end of the banknote separation and feeding operation, the topmost banknote in the storage section is transferred to the feed roller 20 and the gate roller 25.
It remains stuck between the two. In this state, the banknotes B cannot be received and stacked by the impeller 54, so the banknote B held between the feed roller 20 and the gate roller 25 is stored. Make a movement to push it back into the room. This operation of biting and returning banknotes will be explained with reference to FIG. 4. First, the drive motor 42 is driven to lower the push plate 62 by a desired amount. Next, the arm 29 is rotated by the rotation of the cam 45 shown in FIG.
And the guide roller 39 is retracted upward. Next, the arm 49 for pushing back banknotes is rotated counterclockwise from the position shown by the solid line in FIG. , the feed roller 20 is rotated in the opposite direction to the rotation during separation. Through this series of operations, the banknote B caught between the feed roller 20 and the gate roller 25
can be pushed back into the storage section to release the bill from being caught between the rollers 20 and 25.

Next, when receiving and collecting banknotes B that are sent sequentially, as shown in FIG. It is evacuated in the direction of the impeller 54. Finally, the outer periphery of the guide roller 39 at the tip of the arm part 29a of the arm 29 is positioned inside the part where the blades 54A of the impeller 54 are attached, enters the impeller 54, and is held by the blades 54A. The banknote B is prevented from coming into contact with the guide roller 39.

In this state, the stopper 4 that was retracted during the separation operation
7 rotates the feed roller 20 in conjunction with the rotation of the arm 29.
is set in front of the Further, the push plate 62 rises until the uppermost surface of the banknote B comes into contact with the impeller 54 and pushes it up. When the impeller 54 is pushed upward by the rise of the bill B and rotates around the shaft 5, the sensor 6o disposed opposite to one end of the arm 52 detects the upper position of the impeller 54.

Sensor 60 applies its signal to control circuit 61 so that control circuit 61 applies a stop signal to motor 42 . This causes the push plate 62 to stop.

Through the above-described operations, the initial position of the push plate 62 for collecting and receiving banknotes B is determined regardless of whether there are banknotes or not. Next, the push plate 62 is lowered by a predetermined amount.

In this state, the operation of receiving and accumulating banknotes B is started. That is, in synchronization with the conveyance of banknotes B to be stacked, the impeller 54 rotates counterclockwise in FIG.
pushed inside.

This banknote B is held by the blades 54A and rotated by the impeller 54 until it engages with the stopper 47. After that, one bill B collides with the stopper 47 and the impeller 54
The banknotes are separated from the paper banknotes and continue to be stacked on the push plate 62 or on the already stacked banknotes B. During this time, the push plate 62 is stationary, but when the amount of banknotes B accumulated increases and the impeller 54 is pushed upward, the arm 52 rotates clockwise, causing the sensor 60 to operate. The signal from the sensor 60 activates the drive motor 42 to lower the push plate 62. When the push plate 62 descends,
The arm 52 rotates counterclockwise and the sensor 60 returns to its initial state. As a result, the banknotes B are again pushed between the impeller 54 and the stacked banknotes B in an appropriate space or by the clamping force of the impeller 54.

A banknote stacking state is formed with a weak pressing force that allows banknotes to be stacked, and banknotes B can be continuously received and stacked. That is, the impeller 54 follows the accumulated amount of banknotes B.
When the banknotes B are accumulated so that the impeller 54 is pushed up strongly, the push plate 62 is lowered, and a state in which banknotes B can be stably received and collected can be maintained at all times.

Next, when the series of banknote receiving and collecting operations is completed and the banknotes B are to be separated and sent out again, the pickup roller 34 advances to the upper surface of the banknotes B, as shown in FIG. can be played out. Thereafter, the above-described separation operation will be repeated. In this separation operation,
Since the guide roller 39 also advances to the upper surface of the banknote B in synchronization with the pickup roller 34, the banknote is prevented from being deformed by the guide roller 39, such as rising on the counter-banknote sending side, so that the posture of the banknote remains constant. The banknotes can be stably fed out toward the separation point.

That is, interference with a guide member or the like on the upper part of the banknote can be reduced, and conveyance resistance can be reduced.

As a result, misfeeding, skewing, jamming, etc. of one banknote can be prevented.

Further, due to the action of the high friction member disposed on the outer periphery of the guide roller 39, the convex deformation portion 103 at the center of the banknote as shown in FIG. 8(b) and the deformation as shown in FIG. 8(c) occur. Part 1
It is possible to prevent the occurrence of double-shaped overlapping folds 106 as shown in FIG. 05 and FIG. 8(d).

In the embodiment described above, the guide roller 39 has an idling support structure that does not connect the drive system to the tip of the arm portion 29a of the arm 29, but as shown in FIG. 7, it has a support structure that connects the drive system. You can also do this. That is, at the tip of the arm portion 29a of the arm 29, there is a guide roller 39 and the guide roller 3.
A rubber roller 7o connected to a rubber roller 9 is rotatably provided.

Further, a rubber roller 71 is rotatably provided on the arm portion 29a of the arm 29 so as to come into pressure contact with the rubber roller 70 described above, and a rubber roller 37 is rotatably provided so as to come into pressure contact with the rubber roller 71. Further, the arm portion 29a of the arm 29 is provided with the aforementioned rubber roller 37.
A cam 36 that engages with the cam 36 and a gear 35 that rotates together with the cam 36 are rotatably provided. This gear 35 meshes with a gear 38 fixed to the shaft 23.

When separating and sending banknotes, the rotational force of the shaft 23 is applied to the guide roller 39 through teeth @ 38, 35, cam 36, and rubber rollers 37, 71.
．． The guide roller 39 is intermittently driven in synchronization with the intermittent drive of the pickup roller 34 .

By configuring the guide roller 39 in this manner, in addition to producing the same effect as in the case of an idling support structure in which a drive system is not connected, it also provides a synchronized feeding force to the pickup roller 34 on the counter-bill delivery side of the banknote. be able to. Therefore, a large conveying force can be applied to the bills being fed out. Furthermore, this conveying force remains even after the highest banknote among the stacked banknotes is sent out, and can provide a force for sending the next banknote to the separating section side.

Further, if the guide roller 39 described above is made of a material with a coefficient of friction that allows the bill to be fed out, it may have a fixed support structure fixed to the tip of the arm portion 29a of the arm 29, or it may be a surface guide instead of a guide roller. However, similar effects and effects can be obtained.

Although each of the embodiments described above has a structure in which the guide roller 39 as a sheet deformation regulating means swings and retreats integrally with the arm 29, the present invention is not limited to such a structure. do not have. That is, the guide roller 39 is not disposed on the arm 29, but is disposed on an arm rotatably supported on the frame on the counter-bill delivery side, and is synchronized with the pickup roller during bill separation and payout and receiving and collecting. It may be operated to swing and retreat toward the counter-bill delivery side.

In addition, the guide roller is disposed on an arm rotatably supported on the frame on the side perpendicular to the banknote feeding direction, and as in the case described above, the guide roller is synchronized with the pickup roller when separating and feeding banknotes and stacking the banknotes. It may be operated to swing and retreat in a direction perpendicular to the banknote feeding direction. Also,
It goes without saying that the arm on which the guide roller 39 is disposed may be a two-bar link so that the guide roller 39 is always in contact with the banknote surface.

In each of the above-described embodiments, the positions of the pickup roller 34, guide roller 39, and impeller 54 are detected using a 1-position on/off control method, but a 3-position on/off control method that detects the upper and lower surface positions is used. It may be configured in a control format to control the pressing force, or it may be configured as a continuous control system to continuously control the positions and suppressing force of the pickup roller 34, guide roller 39, and impeller 54. Good too.

Further, in the above description, the pickup roller 34 and the guide roller 39 are structured to swing and retreat as necessary, but when the present invention is implemented in a bill dispensing device, there is no need to swing and retreat. .

Moreover, although the above-mentioned embodiments have described a structure in which banknotes are stacked or separated and fed out in a horizontal direction, the present invention can also be applied to a case where the banknotes are in an upright position.

Further, in each of the above-mentioned embodiments, the structure is such that the banknotes are received and the received banknotes are separated and sent out by the friction separating means, and it goes without saying that the present invention can also be applied to a normal separator. Further, instead of the frictional separation method, a vacuum adsorption separation method can be applied in the same way.

In each of the above embodiments, the friction member 74 that comes into contact with the surface of the bill being fed out and applies a force that resists the force that tends to move and deform both sides of the bill toward the center of the bill is located on the outer periphery of the guide roller 39. Although the present invention is not limited to this structure, for example, it goes without saying that the same function and effect can be obtained even if the guide roller 39 is arranged separately from the guide roller 39. do not have.
