Description

The present invention relates to a banknote handling device.

In recent years, automatic teller machines and other banknote processing devices have been required to handle media such as banknotes (hereinafter collectively referred to as "banknotes") with a variety of physical properties (material, printing, degree of circulation, wrinkles, folds). The banknote handling device included in such banknote processing devices is equipped with a separation and feeding mechanism for feeding banknotes one by one from a bundle of multiple banknotes. This separation and feeding mechanism generally employs an overlap separation method in which rollers called feed rollers and gate rollers are arranged so that they overlap each other in a nested manner. The amount of overlap between the two rollers is referred to as the "overlap amount."

In this overlap separation method, when separating and feeding out banknotes, the banknotes are slightly deformed between the above-mentioned feed roller and gate roller. Here, the feed roller is rotated by a motor or the like, while the gate roller is fixed in the feeding direction and does not rotate. Therefore, the top banknote receives a conveying force from the feed roller and is fed out in the rotation direction, but the subsequent banknotes are not fed out because of the entry resistance force of the gate roller. As a result, with the overlap separation method, it is possible to pass only one bill and prevent two or more bills from passing through.

In the overlap separation method, the conveyance force by the feed roller and the resistance force by the gate roller change depending on the state of the minute deformation described above. For this reason, in the overlap separation method, since the amount of overlap determines the separation performance of banknotes, management of the amount of overlap is very important. Therefore, for example, in the banknote handling device (media processing device) of Patent Document 1, even if it is necessary to adjust the amount of overlap between the feed roller and the gate roller due to a malfunction during operation of the automatic teller machine, the amount of overlap between the feed roller and the gate roller can be adjusted. A device has been devised to enable an operator to carry out adjustment work without making a mistake in operation (see Patent Document 1).

Japanese Patent Application Publication No. 2019-117615

In a banknote handling device that employs the overlap separation method, it is required to manage the overlap amount to an appropriate amount. Furthermore, in a banknote handling device that employs the overlap separation method, banknotes may become stuck between the feed roller and the gate roller due to a malfunction or other reason during operation. Note that such a jam of banknotes is also called a "jam," and banknotes in a jammed state are sometimes called "jammed banknotes."

When the jammed bill is pulled in order to remove it between the feed roller and the gate roller, friction occurs between the bill, the feed roller, and the gate roller. Therefore, when removing the banknote, a force in a tensile direction is applied to the banknote, making it difficult to remove the banknote.

The present invention has been made to solve the above problems. That is, one of the objects of the present invention is to be able to appropriately manage the amount of overlap, and to easily remove the jammed banknotes when they become jammed between the feed roller and the gate roller. An object of the present invention is to provide a banknote handling device that can handle paper money.

In order to solve the above-mentioned problems, the banknote handling device of the present invention includes a storage section for storing a plurality of banknotes, a feed roller unit including a feed roller, a feed roller shaft, and a feed roller bearing for feeding the banknotes stored in the storage section out of the storage section, a gate roller unit including a gate roller, a gate roller shaft, and a gate roller bearing that is disposed opposite the feed roller and prevents the banknotes that are not to be fed from being taken out in a closed state in which a portion of a radial surface in the axial direction overlaps with a portion of the radial surface of the feed roller, a first frame that supports the gate roller shaft on the left and right, a second frame that supports the feed roller shaft on the left and right, and a rotating shaft that is inserted into a fulcrum hole formed on the left and right of each of the first frame and the second frame, and by rotating the second frame about the rotating shaft, the feed roller unit can be opened and closed in the axial direction from the closed state. The opening and closing mechanism is capable of opening the gap between the feed roller and the gate roller by moving the feed roller unit until the feed roller unit is in an open state where a part of the feed roller does not overlap with a part of the gate roller, and closing the gap between the feed roller and the gate roller by moving the feed roller unit from the open state to the closed state by rotating the second frame about the rotation shaft; and a pitch plate that has an engagement part that engages with the gate roller bearing, a bearing hole that supports the feed roller bearing is formed, the engagement part fixes the closed state by engaging with the gate roller bearing, and the distance between a predetermined position of the engagement part and a predetermined position of the bearing hole determines the amount of overlap between a part of the radial surface of the feed roller and a part of the radial surface of the gate roller in the axial direction.

According to the present invention, it is possible to appropriately manage the amount of overlap, and when a banknote is jammed between the feed roller and the gate roller, the jammed banknote can be easily removed.

Below, an example of an automated teller machine including a banknote handling device 101 according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of an example of an automatic teller machine. As shown in FIG. 1, the automatic teller machine 100 includes a banknote handling device 101, a card/statement slip processing device 102, a passbook processing device 103, a user operation section 104, and a main body control section 105. It is equipped with

The banknote handling device 101 receives banknotes from a user (deposit) and also discharges banknotes to the user (withdrawals). The card/statement processing device 102 processes the card inserted by the user, prints and releases a transaction statement. The passbook processing device 103 records transaction details in a passbook inserted by the user. The user operation unit 104 displays operation guidance to the user and accepts input instructions from the user. The main body control unit 105 monitors and controls each of these devices. Here, banknotes are an example of paper sheets.

The banknote handling device 101 that handles banknotes will be described below. FIG. 2 is a side view of the banknote handling device 101. As shown in FIG. 2, the banknote handling device 101 includes a deposit/withdrawal port 70, a banknote discriminator 71, a temporary storage 72, a reject box 73, a recycling storage 74, and a banknote as an example of a "conveyance path". It includes a conveyance path 75 and a control section 76. Each of the deposit/withdrawal port 70, bill discriminator 71, temporary storage 72, reject box 73, recycling warehouse 74, and bill conveyance path 75 may also be referred to as a "unit."

The deposit/withdrawal port 70 is equipped with a banknote stacking/separation mechanism 1 (FIG. 3) described below, which feeds the banknotes inserted by the user one by one onto the banknote transport path 75, and also stacks the banknotes transported via the banknote transport path 75 and releases them to the user (dispenses the banknotes so that the user can remove them).

The banknote discriminator 71 measures the optical and magnetic characteristics of the banknote and determines the denomination and authenticity of the banknote. The temporary storage vault 72 temporarily stores the banknote until the transaction is completed. The temporary storage vault 72 is equipped with a banknote accumulation and separation mechanism similar to the banknote accumulation and separation mechanism 1 of the deposit/withdrawal port 70. The temporary storage vault 72, for example, temporarily stores banknotes deposited by a user, and if the user approves the transaction, stores the banknote in the recycle vault 74, and if the user does not approve the transaction, transports the banknote to the deposit/withdrawal port 70 and returns the actual item to the user.

The reject box 73 is a safe that stores banknotes for which transactions have been completed at the time of deposit. The reject box 73 stores banknotes that can only be deposited and banknotes that are not suitable for handling by the banknote handling device 101. Banknotes that are not suitable for handling by the banknote handling device 101 include banknotes that have cuts and folds, and banknotes that have been conveyed in a skewed manner.

The recycle vault 74 has a banknote stacking and separation mechanism that can be used for both deposits and withdrawals. The banknote stacking and separation mechanism stores banknotes inserted by users, and feeds the stored banknotes to the banknote transport path 75 according to the transaction, and dispenses them to the user. The banknote handling device 101 in FIG. 2 is an example in which one reject box 73 and three recycle vaults 74 are installed. However, these reject boxes 73 and recycle vaults 74 can be freely combined, and the number of installed vaults can also be freely set. For example, the banknote handling device 101 may have two reject boxes 73 and two recycle vaults 74.

The banknote transport path 75 transports banknotes to each unit. Therefore, for each transaction, the banknotes pass through the banknote discrimination unit 71 in both directions and are transported in both directions between the deposit/withdrawal port 70, temporary storage vault 72, reject box 73, and recycle vault 74.

The control section 76 monitors and controls each unit. The control section 76 is electrically connected to the main body control section 105 of the automatic teller machine 100. The control unit 76 controls the banknote handling device 101 based on instructions from the main body control unit 105 and reports the state of the banknote handling device 101 to the main body control unit 105.

FIG. 3 is a side partial sectional view showing an example of the configuration of the deposit/withdrawal port 70. As shown in FIG. As shown in FIG. 3, the deposit/withdrawal port 70 is provided with a banknote stacking/separating mechanism 1, which is a separation/feeding mechanism for separating and feeding out the set banknotes BN one by one. The banknote stacking and separating mechanism 1 employs an overlap separation method, and includes a gate roller 10, a feed roller 11, and a pick roller 12. The gate roller 10 and the feed roller 11 are arranged so that they overlap each other in a nested manner (their radial surfaces overlap (that is, their radial surfaces have a portion that partially overlaps in the axial direction)). There is. In other words, the gate roller 10 and the feed roller 11 are spaced apart from each other and are arranged facing each other with their positions shifted in the axial direction, such that a portion of the gate roller 10 and a portion of the feed roller 11 overlap in the axial direction. It is located in Note that this state may also be referred to as a "closed state" because the gap between the gate roller 10 and the feed roller 11 is closed. Here, the amount of overlap between a portion of the gate roller 10 and a portion of the feed roller 11 is also expressed as "overlap amount δ" or "δ". The set banknotes BN are then stored in a position where they come into contact with the pick roller 12.

The bill BN set as described above is conveyed to the bill conveying path 75 (see FIG. 2) in the direction indicated by the dashed arrow a1 as the feed roller 11 and the pick roller 12 rotate while in contact with the pick roller 12. At this time, the feed roller 11 rotates by a motor or the like, while the gate roller 10 is fixed in the payout direction and does not rotate (the gate roller 10 does not rotate and is stopped). Therefore, when the bill BN is inserted, it is subjected to a thrust resistance force from the gate roller 10, so that multiple bills BN are not dispensed at the same time, and it is possible to dispense the bills BN one by one. The resistance force received by the bill BN varies depending on the overlap amount δ between the feed roller 11 and the gate roller 10. The optimal value of the overlap amount δ varies depending on the thickness and rigidity of the bills handled, so the deviation of the overlap amount δ affects the payout performance of the bill BN. Therefore, it is required that the overlap amount δ is managed to be an appropriate amount.

4 and 5 are schematic configuration diagrams of the bill stacking and separating mechanism 1 installed in the deposit/withdrawal port 70. As shown in FIG. 4, in the banknote stacking and separating mechanism 1, a gate roller 10 and a gate roller bearing 21 are attached to a gate roller shaft 13, and a feed roller 11 and a feed roller bearing 22 are attached to a feed roller shaft 14. Note that the gate roller 10, the gate roller shaft 13, and the gate roller bearing 21 may also be referred to as a "gate roller unit." The feed roller 11, the feed roller shaft 14, and the feed roller bearing 22 may also be referred to as a "feed roller unit."

Frames 19A and 19B hold (support) the gate roller shaft 13 and the feed roller shaft 14 on the left and right sides with bearings (not shown) or the like, allowing the gate roller shaft 13 and the feed roller shaft 14 to rotate. For convenience, frame 19A may also be referred to as the "first frame." For convenience, frame 19B may also be referred to as the "second frame."

Frame 19A is formed with a hole (fulcrum hole) through which rotation shaft 18 is inserted. Frame 19B is formed with a fulcrum hole 18L through which rotation shaft 18 is inserted. Frame 19B is rotatable in the direction indicated by dashed arrow b1 in FIG. 5, with rotation shaft 18 as its axis (center).

The fulcrum hole 18L of the frame 19B has a shape through which the rotation shaft 18 can be inserted, and has a shape (for example, an ellipse) whose length is larger than the diameter of the rotation shaft 18 in the longitudinal direction of the pitch plate 16 in the closed state. shape). More specifically, the fulcrum hole 18L of the frame 19B is larger than the radial surface of the rotating shaft 18 and has a long axis along the longitudinal direction of the pitch plate 16 in the closed state. The length of the rotary shaft 18 is longer than the diameter of the rotating shaft 18. Therefore, in the closed state, the rotating shaft 18 is inserted into the fulcrum hole 18L of the frame 19B in a state where it is rotatable and movable within the fulcrum hole 18L. When the frame 19B rotates about the rotation shaft 18, the rotation shaft 18 itself may or may not rotate in conjunction with the rotation of the frame 19B. Specifically, for example, the rotating shaft 18 may be a fixed shaft that does not rotate itself when the frame 19B rotates about the rotating shaft 18. Furthermore, when the frame 19B rotates, the frame 19B may be fixed to the rotating shaft 18 and rotated in complete conjunction with the rotation of the rotating shaft 18.

The feed roller bracket 15 is attached to the feed roller shaft 14 so as to surround the frame 19B, and can rotate around the feed roller shaft 14 in the direction indicated by the solid arrow b2 in Figure 5.

The pitch plate 16 fixes the position of the feed roller 11 and the position of the gate roller 10, thereby fixing (determining) the overlap amount δ. The pitch plate 16 is attached to the feed roller bracket 15 by a fixing screw 17.

The claw tip portion 16g, which is the engagement portion of the pitch plate 16 with the gate roller bearing 21, engages with the gate roller bearing 21, and also engages with a portion of the hole forming surface 16a1 of the bearing hole 16a of the pitch plate 16. A state in which the roller bearing 22 is in contact with a part of the roller bearing 22 (to be more specific, the right side with respect to the central axis CL1 that divides the hole forming surface 16a1 of the bearing hole 16a of the pitch plate 16 into two at the center in the longitudinal direction). The pitch plate 16 is assembled to the feed roller 11 and the gate roller 10 with a part of the hole forming surface 16a1 including the rightmost point RP1 of the bearing hole 16a in contact with a part of the feed roller bearing 22). It is attached (attached). As a result, the feed roller 11 and the gate roller 10 are fixed in a closed state that closes the space between them, and furthermore, the position of the gate roller shaft 13, the position of the feed roller shaft 14, and the overlap amount δ are adjusted at the tip of the claw. It is fixed by an amount corresponding to a pitch A (interval) between a predetermined position on the inner surface 16g1 of the bearing hole 16g and the rightmost point RP1 of the bearing hole 16a.

Furthermore, the feed roller bracket 15 and the frame 19B are attached by a spring or the like (not shown), and a force acts on the pitch plate 16 attached to the feed roller bracket 15 in a direction that causes it to come into contact with the gate roller bearing 21.

Further, at least one of the two fulcrum holes 18L formed in the frame 19B, around which the rotating shaft 18 of the frame 19B rotates, has the above-mentioned oval shape (both in this example). That is, both the fulcrum hole 18L formed at the left end of the frame 19B and the fulcrum hole 18L formed at the right end of the frame 19B have an oval shape. Note that only one of the two fulcrum holes 18L may have an oval shape.

By making the fulcrum hole 18L of the rotation fulcrum part of the frame 19B into an oblong hole shape, the rotation shaft 18 can move in the horizontal direction (that is, in the direction along the longitudinal direction of the pitch plate 16 in the closed state). Become.

When a bill BN gets caught between the gate roller 10 and the feed roller 11 during bill separation, a force is applied to the pitch plate 16 and frame 19B holding the feed roller shaft 14, which is applied with a force that spreads outward from each roller. Therefore, even if the frame 19B is distorted (deformed) and the feed roller shaft 14 becomes diagonally attached to the gate roller shaft 13, the rotating shaft 18 moves within the fulcrum hole 18L, so that when bills are separated, the claw tips 16g of either the left or right pitch plate 16 abut against the gate roller bearing 21, ensuring the desired overlap amount (design value).

In addition, if the rotating shaft 18 does not move in the horizontal direction and the frame 19B is distorted (deformed) and the feed roller shaft 14 is attached diagonally to the gate roller shaft 13, The claw tip 16g of the pitch plate 16 on one side abuts the gate roller bearing 21, but the claw tip 16g of the pitch plate 16 on the opposite side does not abut the gate roller bearing 21, and the overlap amount δ is different between the left and right sides. There is a possibility that it will happen.

Next, the shape of the pitch plate 16 will be described. Figures 6A and 6B are side views for explaining an example of the shape of the pitch plate 16. At a predetermined position in the longitudinal direction of the pitch plate 16 (the inner longitudinal cutout start position PS1), the pitch plate 16 includes a claw tip 16g on the left side of an imaginary line Ln1 that divides the pitch plate 16 in half in the longitudinal direction, and a rectangular portion 16h on the right side of the imaginary line Ln1. The claw tip 16g has a claw shape formed by cutting out a portion of the rectangular planar shape.

The rectangular portion 16h has a rectangular outer shape, and is formed with a bearing hole 16a for supporting the feed roller bearing 22 and a fastening hole 16b for passing the fixing screw 17 located on the right side of the bearing hole 16a. ing.

The bearing hole 16a of the feed roller bearing 22 of the pitch plate 16 is formed in an oval shape with a long axis along the longitudinal direction of the pitch plate 16. Thereby, the amount of overlap δ can be adjusted to the amount of overlap of two patterns. That is, as a result, the predetermined position of the claw tip 16g (in the longitudinal direction, the most innermost position of the claw tip 16g (the farthest position with respect to the bearing hole 16a)) and the predetermined position of the bearing hole 16a. (the right vertex (the vertex on the far side from the claw tip 16g (the farthest position from the claw tip 16g in the longitudinal direction))) and the overlap amount defined by the pitch A, and the claw tip A predetermined position of the bearing hole 16a (the apex on the side closer to the claw tip 16g (in the longitudinal direction, the innermostmost position of the claw tip 16g) The amount of overlap defined by the pitch B between the position closest to 16g) and the amount of overlap defined by the pitch B can be adjusted to two patterns. Note that pitch A may also be referred to as a "first pitch" for convenience. Pitch B may also be referred to as a "second pitch" for convenience.

As described above, the overlap amount δ is an important value related to the payout performance of the banknote BN, so the processing accuracy of the pitch between the predetermined position of the claw tip 16g of the pitch plate 16 and the predetermined position of the bearing hole 16a of the pitch plate 16 ensures the accuracy of the overlap amount δ. For this reason, the processing accuracy of the pitch of the pitch plate 16 is such that each of the pitch A and pitch B, which are the pitch distances (spacings) from the predetermined position to the predetermined position of the bearing hole 16a, is processed with high precision. That is, the pitch plate 16 is processed so that the difference in absolute value between the pitch A and the first design value is a predetermined value (e.g., 0.03 mm) or less, and the difference in absolute value between the pitch B and the second design value is a predetermined value (e.g., 0.03 mm) or less. In other words, the pitch plate 16 is formed with the claw tip 16g and the bearing hole 16a so that the difference in absolute value between pitch A and the first design value is a predetermined value (e.g., 0.03 mm) or less, and the claw tip 16g and the bearing hole 16a are formed so that the difference in absolute value between pitch B and the second design value is a predetermined value (e.g., 0.03 mm) or less.

Note that the first design value is a value set so that the overlap amount δ becomes a desired overlap amount δ1 in a first fixed state (described later) in an initial state (an unused state of the banknote handling device 101). Yes, and the second set value is a desired overlap amount δ2 in which the overlap amount δ is larger (longer) than the overlap amount δ1 in the later-described second fixed state in the initial state (unused state of the banknote handling device 101). The value is set so that
Further, as shown in FIG. 6B, the pitch plate 16 is provided with a gap SP1 and a gap SP2 to facilitate opening and closing operations between the gate roller 10 and the feed roller 11. The gap SP1 and the gap SP2 are gaps between the gate roller bearing 21 and the claw tip 16g. This gap has no effect on the amount of overlap. This is because, as described above, when the banknote BN is bitten by the gate roller 10 and the feed roller 11, force is applied in the direction in which the gate roller 10 and the feed roller 11 spread outward, as indicated by the black arrows in the figure. Therefore, the gate roller shaft 13 hits a part (edge part) of the inner side of the claw tip 16g of the pitch plate 16, and the pitch plate 16, the feed roller shaft 14 attached to it, and the feed roller bracket 15 are marked with white arrows. Force is applied in the direction. Therefore, the gate roller shaft 13 does not swing in the direction in which the gaps SP1 and SP2 provided in the pitch plate 16 exist, which is the direction in which the overlap amount is smaller than the designed amount. value) can be secured.

As described above, the banknote handling device 101 can adjust the overlap amount δ in two patterns. The method of adjusting the overlap amount δ will be described below. Figures 7A and 7B are side views for explaining the method of adjusting the overlap amount δ. As shown in Figure 7A (Figure 7B), the shape of the bearing hole 16a of the feed roller bearing 22 of the pitch plate 16 is such that the feed roller bearing 22 can be inserted and has a width in the longitudinal direction greater than the diameter of the feed roller bearing 22 (in this example, an elliptical shape with a major axis along the longitudinal direction), so that the overlap amount δ can be adjusted in two patterns.

That is, as shown in FIG. 7A, the claw tip 16g engages with the gate roller bearing 21, and is located on the right side of the central axis CL1 that divides the bearing hole 16a of the pitch plate 16 into two in the longitudinal direction of the pitch plate 16 ( The fixing screw 17 is fastened with at least a portion of the hole forming surface (hole forming part) on the side far from the claw tip 16g pressing the feed roller bearing 22 in the A direction against the feed roller bracket 15.

By fixing the gate roller bearing 21 and the feed roller bearing 22 in this state, the overlap amount δ is fixed to the overlap amount δ1 corresponding to this fixed state (also referred to as the "first fixed state"). be done.

As shown in FIG. 7B, the claw tip 16g engages with the gate roller bearing 21, and the hole on the left side of the central axis CL1 of the bearing hole 16a of the pitch plate 16 (closer to the claw tip 16g) By fastening the fixing screw 17 with at least a part of the forming surface (hole forming part) pressing the feed roller bearing 22 in the direction B, and fixing the gate roller bearing 21 and the feed roller bearing 22 in this state. , the overlap amount δ is fixed to an overlap amount δ2 corresponding to this fixed state (also referred to as a “second fixed state”).

For example, in the banknote handling machine 101 that has been adjusted to a desired overlap amount δ (= δ1) in the first fixed state, the overlap amount δ1 may deviate (become smaller) from the desired overlap amount δ after many years of use. In this case, by switching to the second fixed state, the feed roller bearing 22 is fixed at a position closer to the gate roller bearing 21 than in the first fixed state, so that the deviation from the desired overlap amount δ can be easily adjusted (increased from the overlap amount δ1) (i.e., the overlap amount can be adjusted to the desired overlap amount δ (= δ2)).
Since the bearing hole 16a has an elliptical shape, friction between the hole forming surface 16a1 and the feed roller bearing 22 is reduced, thereby reducing wear of the hole forming surface 16a1 and the feed roller bearing 22. The fastening hole 16b is formed to have an elliptical shape having a major axis along the longitudinal direction of the pitch plate 16. It is preferable that the longitudinal width of the fastening hole 16b is formed to be longer than the width over which the feed roller bearing 22 can move along the longitudinal direction inside the bearing hole 16a. This makes it easier to avoid the feed roller bearing 22 hitting the fastening hole 16b before hitting at least a part of the hole forming surface 16a1 when the feed roller bearing 22 is slid to adjust the overlap amount δ.

Next, the procedure for removing jammed banknotes will be explained. 8A and 8B are schematic diagrams showing an opening/closing mechanism that opens and closes between the feed roller 11 and the gate roller 10, which is provided to simplify the work of removing jammed banknotes.

The feed roller bracket 15 is attached with a spring (not shown), and the pitch plate 16 has a claw tip 16g engaged with the gate roller bearing 21, and a part of the hole forming surface 16a1 of the bearing hole 16a. is in contact with the feed roller bearing 22 in a state where it is pressed against the feed roller bearing 22.

As shown in FIG. 8A, by rotating the feed roller bracket 15 in the direction indicated by the solid arrow d1, the pitch plate 16 that fixes the positions of the gate roller shaft 13 and the feed roller shaft 14 also rotates. Therefore, by rotating the feed roller bracket 15, the engagement between the claw tip 16g and the gate roller bearing 21 is released, and the fixing of the positions of the gate roller shaft 13 and the feed roller shaft 14 by the pitch plate 16 is released. be done.

Therefore, as shown in FIG. 8B, the frame 19B is rotatable about the rotation shaft 18 in the rotation direction indicated by the broken line arrow d2 (the rotation direction in which the feed roller 11 moves away from the gate roller 10). As the frame 19B rotates, the feed roller shaft 14 and the feed roller bearing 22 attached to the frame 19B also rotate in the same direction, so that a portion of the gate roller 10 and a portion of the feed roller 11 do not overlap in the axial direction ( ), and a gap X is created between the gate roller 10 and the feed roller 11. By creating this gap X, jammed banknotes generated between gate roller 10 and feed roller 11 can be easily removed, and the possibility that jammed banknotes can be removed without being damaged can be improved.
<Effect>
As described above, the banknote handling device 101 according to the embodiment of the present invention can appropriately manage the overlap amount δ, and when a banknote BN is jammed between the gate roller 10 and the feed roller 11, It is possible to easily remove jammed banknotes BN. Furthermore, the banknote handling device 101 can reduce the possibility that the banknote BN will be damaged when removing a jammed banknote BN.

The present invention is not limited to the above-described embodiments, and various modifications can be adopted within the scope of the present invention. The shapes and numerical values given in the above embodiments are merely examples, and shapes and numerical values different from these may be used as necessary within the scope of the present invention. For example, in the above embodiment, the shape of the bearing hole 16a is such that the feed roller bearing 22 can be inserted therethrough and the width in the longitudinal direction is larger than the diameter of the radial surface of the feed roller bearing 22. It may have a shape other than circular. For example, in the embodiment described above, the fulcrum hole 18L may have a shape other than an ellipse as long as the rotating shaft 18 can be inserted therethrough and the width in the longitudinal direction is larger than the diameter of the radial surface of the rotating shaft 18. It may be a shape.
