Description

[Technical field]

[0001] The present invention relates to a roller, a paper sheet separator, and a paper sheet processing device, and is suitable for use in cash register change dispensers used at the cash registers of retail stores such as supermarkets and convenience stores. [Background technology]

[0002] In recent years, cash register change dispensers that combine a POS register connected to a POS (Point Of Sales) system or the like with a change dispenser that processes the deposit and withdrawal of banknotes and coins have become widespread. Among these change dispensers, there are banknote processing devices that process banknotes, for example, that have a banknote deposit and withdrawal section that allows a cashier to insert banknotes and have the cashier take out the banknotes dispensed from a storage vault, a transport section that transports the banknotes, a recognition section that recognizes the type of the inserted banknotes, and a storage vault that stores banknotes by denomination and dispenses banknotes for change.

[0003] Conventionally, this storage includes, for example, a vertically long box-shaped banknote accumulation space formed by a guide, a transport path extending in the front-rear direction connecting to the upper part of the banknote accumulation space, feed rollers and reverse rollers provided at the connection point between the banknote accumulation space and the transport path and arranged facing each other in the vertical direction across the transport path, a stage that moves vertically inside the banknote accumulation space, and a picker roller located at the upper end of the banknote accumulation space (see, for example, Patent Document 1). The feed rollers and reverse rollers form a banknote intake / discharge port between the banknote accumulation space and the transport path.

[0004] As shown in Fig. 17, such a feed roller includes a feed roller 342 that is configured with a feed boss 360 made of low-friction resin or metal so as not to generate force for feeding banknotes, and a feed rubber 362 made of high-friction rubber so as to generate force for feeding banknotes. The feed roller 342 is configured by bonding the feed boss 360 and the feed rubber 362, which are manufactured separately, with an adhesive or the like. The feed roller 342 is configured by bonding an adhesive surface consisting of a part of the surface of the feed boss 360 on the outer periphery side of the feed roller 342 and a part of the surface of the feed rubber 362 on the inner periphery side of the feed roller 342, which is a surface where the feed boss 360 and the feed rubber 362 come into contact, with an adhesive 382, ​​thereby preventing the positional relationship between the feed boss 360 and the feed rubber 362 from changing and preventing the feed rubber 362 from coming off the feed boss 360.

[0005] [Patent Document 1] JP 2008-63075 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, there is a problem in that the low friction material such as resin or metal used in the feed boss and the high friction material such as rubber used in the feed rubber have poor bonding properties, making manufacturing difficult.

[0007] The present invention has been made in consideration of the above points, and aims to propose a roller, a paper sheet separating device, and a paper sheet processing device that can improve the bonding strength between a low friction member and a high friction member. [Means for solving the problem]

[0008] In order to solve this problem, the roller of the present invention includes a high friction member having an axially extending fitting protrusion formed on the inner periphery thereof, a low friction member having a radial movement restricting hole extending along the axial direction on the outer periphery side of the rotating shaft, into which the fitting protrusion fits and which surrounds at least a part of the fitting protrusion, and an axial movement restricting portion that abuts against one side and the other side of the high friction member in the axial direction. The radial movement restricting hole is formed with a retaining portion located on the outer circumferential side of the fitting protrusion, and is formed further outward in the axial direction than the axial movement restricting surface, which is the axial inner surface of the axial movement restricting portion formed at both axial ends of the low friction member, and the fitting protrusion enters the axial movement restricting portion further outward in the axial direction than the axial movement restricting surface. I did so.

[0009] The paper sheet separating device of the present invention includes a transport path connected to a paper sheet storage space that stores paper sheets, a feed roller that is provided at a connection point between the paper sheet storage space and the transport path and that feeds paper sheets from the paper sheet storage space to the transport path, an opposing roller that is disposed opposite the feed roller across the transport path and that forms an intake port for paper sheets between the feed roller, a stage that is movable within the paper sheet storage space and that accumulates paper sheets, and a roller that comes into contact with the paper sheets accumulated on the stage and that extracts the paper sheets. Paper sheets and a picker roller that sends the feed roller to an inlet, the feed roller having a high friction member with an axially extending fitting protrusion formed on the inner periphery thereof, a low friction member having a radial movement restricting hole that extends axially on the outer periphery side of the rotating shaft, the fitting protrusion fitting into the fitting protrusion and surrounding at least a part of the fitting protrusion, and an axial movement restricting portion that abuts against one side and the other side of the high friction member in the axial direction. The radial movement restricting hole is formed with a retaining portion located on the outer circumferential side of the fitting protrusion, and is formed further outward in the axial direction than the axial movement restricting surface, which is the axial inner surface of the axial movement restricting portion formed at both axial ends of the low friction member, so that the fitting protrusion enters the axial movement restricting portion further outward in the axial direction than the axial movement restricting surface. I did so.

[0010] According to the present invention, the radial movement restricting hole prevents the high friction member from moving radially outward relative to the low friction member, and the axial movement restricting portion prevents the high friction member from moving in the thrust direction relative to the low friction member.

[0011] Furthermore, the roller of the present invention is provided with a high-friction member having an axially extending fitting protrusion formed on its inner side, a low-friction member having a radial movement restricting hole formed therein that extends axially outer than the rotating shaft and into which the fitting protrusion fits and surrounds at least a portion of the fitting protrusion, and a joining member that is arranged on at least a portion of the contact surface between the high-friction member and the low-friction member and joins the high-friction member and the low-friction member.

[0012] Furthermore, in the paper sheet separating device of the present invention, there are provided a conveying path connected to a paper sheet storage space that stores paper sheets, a feed roller that is provided at the connection between the paper sheet storage space and the conveying path and that pays out paper sheets from the paper sheet storage space to the conveying path, an opposing roller that is arranged opposite the feed roller across the conveying path and forms an intake port for the paper sheets between the feed roller, a stage that is movable within the paper sheet storage space and that accumulates paper sheets, and a picker roller that contacts the paper sheets accumulated on the stage and sends the media to the intake port, and the feed roller is provided with a high-friction member having an axially extending fitting protrusion formed on its inner side, a low-friction member that extends axially on the outer side of the rotating shaft and has a radial movement restricting hole formed therein into which the fitting protrusion fits and surrounds at least a part of the fitting protrusion, and a joining member that is provided at least a part of the contact surface between the high-friction member and the low-friction member and that joins the high-friction member and the low-friction member.

[0013] According to the present invention, the radial movement restricting hole prevents the high friction member from moving radially outward relative to the low friction member, and the joining member prevents the high friction member from moving in the thrust direction relative to the low friction member.

[0014] Furthermore, the paper sheet processing apparatus of the present invention is provided with the above-mentioned paper sheet separating device. Effect of the Invention

[0017] Hereinafter, modes for carrying out the invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

[0018] 1. First embodiment [1-1. Configuration of the banknote deposit / withdrawal device] As shown in Fig. 1, the banknote deposit and withdrawal device 1 is a banknote change machine connected to a cash register installed at a checkout counter (a so-called cash register) of a retail store such as a supermarket or a convenience store. The cash register is operated by a cashier when a customer pays for products he or she wishes to purchase. In the following description, the side facing the cashier or the like (hereinafter referred to as the operator) and the opposite side are respectively defined as the front and rear, and further the left and right and top and bottom are defined as viewed from the operator.

[0019] The banknote deposit and withdrawal device 1 is provided, within a banknote deposit and withdrawal device housing 2, with a control unit 4 for overall control, a banknote deposit and withdrawal unit 6 for inserting and ejecting banknotes, a transport unit 8 for transporting banknotes, a banknote discrimination unit 10 for discriminating the type of banknote, etc., banknote storage vaults 12A, 12B, and 12C for storing banknotes, a reject vault 14, and a recovery vault 16, etc. Hereinafter, the banknote storage vaults 12A, 12B, and 12C are also collectively referred to as banknote storage vaults 12.

[0020] The control unit 4 has a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc., which are not shown, and performs various processes by executing predetermined programs read from the ROM etc. by the CPU, thereby providing overall control of the entire banknote deposit and withdrawal device 1.

[0021] The banknote deposit / withdrawal unit 6 is provided at the front upper part of the banknote deposit / withdrawal device 1, has a banknote tray 6A formed in a square receptacle shape corresponding to the shape of the banknote protruding forward, and has a roller, a vane wheel, etc. that are driven to rotate inside. The banknote deposit / withdrawal unit 6 separates banknotes stored inside and feeds them one by one to the transport unit 8, and has a stacking and feeding device 20 that stacks banknotes sent along the transport unit 8 inside. When a cashier places banknotes deposited by a customer on the banknote tray 6A during settlement, the banknote deposit / withdrawal unit 6 takes in the banknotes one by one and delivers them to the transport unit 8 in sequence. When banknotes for change are transported from the transport unit 8, the banknote deposit / withdrawal unit 6 discharges the banknotes so that they are stacked one by one on the banknote tray 6A, and allows the cashier to take them out.

[0022] The transport unit 8 is composed of various rollers, pulleys, belts, blades, etc., which are appropriately arranged to form a transport path 8W that mainly extends in the front-rear direction. The transport unit 8 transmits driving force to the rollers and belts via motors, gears, etc. (not shown), transporting the banknotes along the transport path 8W with the short side direction of the banknote as the travel direction, and also switches the destination of the banknotes by appropriately rotating the blades.

[0023] The banknote validator 10 has an optical sensor, a magnetic sensor, etc., and validates the denomination and authenticity of the banknote, or the presence and degree of damage, and sends the validation result to the controller 4. In response to this, the controller 4 conveys the banknote to the banknote storage vault 12 if the banknote is legitimate, returns the banknote to the banknote deposit / withdrawal unit 6 if the banknote is not legitimate, and conveys the banknote to the reject vault 14 if the banknote is damaged.

[0024] Each of the banknote storage vaults 12 (12A, 12B, and 12C) has the same configuration, the denomination of banknotes to be stored is preset, and each is formed in a rectangular parallelepiped shape to form a space inside. Each of the banknote storage vaults 12 (12A, 12B, and 12C) has a stacking and dispensing device 30 (30A, 30B, and 30C) that stacks banknotes inside and dispenses the stacked banknotes to the outside. Hereinafter, the stacking and dispensing devices 30A, 30B, and 30C are collectively referred to as stacking and dispensing device 30. Each of the banknote storage vaults 12 (12A, 12B, and 12C) stacks and stores the banknotes transported by the transport unit 8 in the space in sequence. Incidentally, each of the banknote storage vaults 12A, 12B, and 12C stores the banknotes by denomination as the banknotes are transported by denomination. The banknote storage vault 12 also appropriately rotates a vane wheel, rollers, etc. to eject the stored banknotes one by one and deliver them to the transport unit 8.

[0025] The rejected banknote vault 14 is provided at the lower front part of the banknote deposit and withdrawal device 1, i.e., below the banknote deposit and withdrawal unit 6, and has a space formed therein capable of accumulating several tens of banknotes. Banknotes that have been identified as damaged by the banknote discrimination unit 10 (hereinafter also referred to as rejected banknotes) are transported by the transport unit 8 to the rejected banknote vault 14. In response to this, the rejected banknotes that have been transported thereto are sequentially accumulated and stored in the rejected banknotes.

[0026] The collection box 16 is provided below the reject box 14 at the lower front part of the banknote deposit and withdrawal device 1, and forms a space inside which several hundred banknotes can be accumulated. When a cashier or the like presses an operation button on a predetermined operation display unit, the banknote deposit and withdrawal device 1 transports the banknotes accumulated in the banknote storage box 12 to the collection box 16 by the transport unit 8. In response to this, the collection box 16 sequentially accumulates and stores the banknotes (hereinafter also referred to as recovered banknotes) that are transported sequentially. In addition, when a cashier or the like stores banknotes for change in the collection box 16 and then presses an operation button on a predetermined operation display unit, the banknote deposit and withdrawal device 1 ejects the banknotes one by one from the collection box 16 and transports them sequentially to the banknote storage box 12 by the transport unit 8.

[0027] [1-2. Configuration of the accumulation and feeding device] Next, the configuration of the accumulating and dispensing device 30 (30A to 30C) of each banknote storage vault 12 (12A to 12C) will be described. Since the banknote storage vaults 12A to 12C are provided with the accumulating and dispensing devices 30A to 30C having the same configuration, respectively, the configuration of the accumulating and dispensing device 30A provided in the banknote storage vault 12A will be described here as an example. Note that Figs. 2 and 3 show the main part of the accumulating and dispensing device 30A with some parts omitted. Furthermore, since the accumulating and dispensing device 20 has almost the same configuration as the accumulating and dispensing device 30, a description thereof will be omitted.

[0028] 2 and 3, the accumulating and dispensing device 30A is provided at the top of a vertically long box-shaped banknote accumulating space 40. The accumulating and dispensing device 30A has a feed roller 42, an opposing roller 44, a guide 46, a conveying path 48, a stage 50, and a picker roller 52.

[0029] The feed roller 42 and the opposing roller 44 are provided at a connection point between the banknote accumulation space 40 and the transport path 48, and are arranged opposite each other in the vertical direction with the transport path 48 in between. The upper feed roller 42 and the lower opposing roller 44 are arranged so that their peripheral surfaces slightly overlap each other in the vertical direction, and form a gate 45, which is a banknote intake and discharge port, between the banknote accumulation space 40 and the transport path 48.

[0030] The feed roller 42 is composed of a feed boss 60 made of low-friction resin or metal so as not to generate a force for feeding the banknote BL, and a feed rubber 62 made of high-friction rubber so as to generate a force for feeding the banknote BL. The feed roller 42 is rotatable in both the clockwise direction in FIG. 2 (the rotation direction when the banknote BL is fed to the transport path 48) and the counterclockwise direction (the rotation direction when the banknote BL is discharged to the banknote stacking space 40) by a power transmission system (not shown). In contrast, the opposing roller 44 is rotatable only in the clockwise direction in FIG. 2 (the rotation direction when the banknote is discharged) by a power transmission system (not shown). This prevents the opposing roller 44 from simultaneously feeding two or more banknotes BL when separating them.

[0031] The guide 46 has a front guide 46f located at the front side of the banknote accumulation space 40, a rear guide 46b located at the rear side of the banknote accumulation space 40, a left guide 46l located on the left side of the banknote accumulation space 40, and a right guide 46r located on the right side of the banknote accumulation space 40. The guide 46 forms the banknote accumulation space 40 whose front-to-back and left-to-right dimensions are slightly larger than the size of the banknotes BL by the front guide 46f, the rear guide 46b, the left guide 46l, and the right guide 46r.

[0032] The front guide 46f covers the opposing roller 44 and allows the opposing roller 44 to protrude from a hole (not shown) into the transport path 48. The front guide 46f further includes a front guide guiding portion 47 that extends in a straight line obliquely upward and forward from the upper end toward the gate 45. The front guide guiding portion 47 guides one end (i.e., the front end) of the banknotes BL stacked on the stage 50 on the gate 45 side to the gate 45 when the banknotes are fed out.

[0033] The conveying path 48 extends in the front-rear direction, with its front side connected to the conveying path 8W (FIG. 1) and its rear side connected to the upper front end of the banknote stacking space 40. The stacking and paying out device 30A also has a travel sensor 49 that detects banknotes BL passing through the conveying path 48.

[0034] The stage 50 is movable vertically within the banknote stacking space 40 by a power transmission system (not shown), and is urged upward by a urging member (not shown), such as a spring. When banknotes are fed out, the stage 50 moves upward and presses the topmost banknote BL among the stacked banknotes against the lower end portion of the picker roller 52, thereby sandwiching the banknote BL between the stage 50 and the picker roller 52 and generating an appropriate feed force.

[0035] The picker roller 52 is located at the upper end of the banknote accumulation space 40 (on the banknote accumulation space 40 side as viewed from the gate 45) so as to face the stage 50 in the vertical direction. The picker roller 52 is connected to the feed roller 42 via a picker arm 54 and a picker shaft 55, and is capable of moving in the vertical direction along an arc centered on the rotation axis of the feed roller 42. The rotation of the feed roller 42 is transmitted to the picker roller 52 by a drive belt 56, so that the picker roller 52 rotates in synchronization with the feed roller 42.

[0036] Furthermore, a picker rubber 52g, which is a high friction member, is attached to a part of the outer circumferential surface of the picker roller 52. The distance from the rotation shaft of the picker roller 52 to the outer circumferential surface of the picker rubber 52g is slightly longer than the distance from the rotation shaft of the picker roller 52 to the outer circumferential surface of the picker roller 52. Therefore, the outer circumferential surface of the picker rubber 52g protrudes slightly from the outer circumferential surface of the picker roller 52.

[0037] When banknotes are dispensed, the picker roller 52 rotates clockwise in FIG. 2, thereby sending the banknote BL pressed by the stage 50 (i.e. the top banknote BL stacked on the stage 50) forward, parallel (or nearly parallel) to the horizontal direction, toward the gate 45 located in front.

[0038] [1-3. Payout operation by the accumulation and payout device] Next, a description will be given of the feeding operation when the stacking and feeding device 30 (30A to 30C) feeds out the banknotes BL. Again, as an example, the feeding operation by the stacking and feeding device 30A provided in the banknote storage vault 12A will be described.

[0039] In the stacking and dispensing device 30A, when dispensing banknotes, the stage 50 is pushed upward so that the top banknote BL is pressed against the outer peripheral surface of the picker roller 52, and the picker roller 52 is rotated clockwise in Figure 2 to press the picker rubber 52g of the picker roller 52 against the banknote BL stacked on the stage 50.

[0040] In this state, when the picker roller 52 rotates, the top banknote BL is sent to the gate 45. The banknote BL sent to the gate 45 is passed across the travel sensor 49 by the feed rollers 42 and fed to the conveying path 48. The travel sensor 49 detects that the banknote BL has crossed, and notifies the control unit 4 of the detection result. The control unit 4 detects that the banknote BL has been conveyed based on the obtained detection result.

[0041] [1-4. Feed roller configuration] As shown in Figures 4, 5 and 6, the feed roller 42 is generally cylindrical and rotates about a rotation axis Ax located at the center of a feed roller shaft (not shown) that passes through the center of the cylindrical shape in the left-right direction. The feed roller 42 is configured by joining a feed boss 60 and a feed rubber 62 together without using an adhesive. Note that, although the peripheral side surface of the feed rubber 62 has an uneven shape when viewed along the rotation direction of the feed roller 42 in Figure 6, the uneven shape is not shown in Figures 4 and 7. The same applies to the second and third embodiments described later.

[0042] In the following, in the feed roller 42, the direction along the rotation axis Ax is also referred to as the axial direction (thrust direction Dt), the direction from the rotation axis Ax toward the outer circumferential surface (circumferential side surface) is also referred to as the outer circumferential direction (radial outer direction Dro), the direction from the outer circumferential surface (circumferential side surface) toward the rotation axis Ax is also referred to as the inner circumferential direction (radial inner direction Dri), the direction along the outer circumferential direction and the inner circumferential direction is also referred to as the radial direction (radial direction Dr), and the clockwise and counterclockwise directions in Figure 2 in which the feed roller 42 rotates are also referred to as the rotational direction (circumferential direction).

[0043] [1-4-1. Feed boss configuration] The feed boss 60 is generally cylindrical and occupies most of the feed roller 42. A cylindrical shaft hole 64 is formed in the center of the feed boss 60 so as to extend axially from one end face to the other end face of the feed boss 60 through the inside of the feed boss 60. A feed roller shaft (not shown) is inserted into the shaft hole 64. A rubber fitting 65, which is recessed toward the inner circumferential side, is formed on the outer periphery of the feed boss 60 over a rotation angle range of about 90°. The feed rubber 62 is fitted into the rubber fitting 65 to form the feed roller 42.

[0044] [1-4-1-1. Outer periphery configuration] The outer periphery of the feed boss 60 is formed with a boss outer periphery surface 66 along a circular arc shape. In addition, two boss outer periphery grooves 67g recessed from the boss outer periphery surface 66 toward the inner periphery are formed on the outer periphery of the feed boss 60 over the entire circumference except the rubber fitting portion 65. Therefore, on the outer periphery of the feed boss 60, three boss outer periphery protrusions 67p, which are shaped along the circular arc shape of the feed roller 42 and protrude from the outer periphery surface of the boss outer periphery groove 67g toward the outer periphery and have a predetermined radial thickness, are formed over the entire circumference except the rubber fitting portion 65, that is, over the same circumferential range as the boss outer periphery groove 67g. In this way, the outer periphery of the feed boss 60 has an uneven shape along the axial direction. The end face of the boss outer periphery protrusion 67p facing the rubber outer periphery protrusion 75p (described later) of the feed rubber 62 in the circumferential direction is the outer periphery protrusion circumferential inner end face 67pS. The outer peripheral protrusion circumferential inner end surface 67pS is in contact with the outer peripheral protrusion circumferential outer end surface 75Sc of the feed rubber 62.

[0045] [1-4-1-2. Configuration of axial end wall] An axial end wall 68 is formed on one end side and the other end side of the rubber fitting portion 65 of the feed boss 60 in the axial direction. The axial end wall 68 is a wall portion that protrudes from the inner periphery side toward the outer periphery side so as to have a shape recessed toward the inner periphery side along the circumferential direction with respect to the portion of the feed boss 60 other than the rubber fitting portion 65 (i.e., the boss outer periphery protrusion 67p). Therefore, the axial end wall 68 has a shorter radius than the portion of the feed boss 60 other than the rubber fitting portion 65. The feed roller 42 exposes a rubber outer periphery protrusion 75p (described later) of the feed rubber 62 to the outside from the outer periphery side of the axial end wall 68.

[0046] The axial end wall 68 has an axial end wall outer surface 68So, which is a plane along a direction perpendicular to the axial direction, including the radial direction, formed on the axial outer surface. The axial end wall 68 has an axial movement restricting surface 68Si, which is a plane along a direction perpendicular to the axial direction, including the radial direction, formed on the axial inner surface. The axial movement restricting surface 68Si abuts against a main body axial end surface 78Sa (described later) of the feed rubber 62. For this reason, the feed boss 60 has the axial end wall 68 disposed so as to sandwich the main body axial end surface 78Sa of the positioning recessed portion 79 (described later) of the feed rubber 62 from the outside in the axial direction. As a result, the feed boss 60 restricts the movement of the feed rubber 62 in the axial direction relative to the feed boss 60, and prevents the feed rubber 62 from coming off the feed boss 60 in the axial direction.

[0047] [1-4-1-3. Boss body structure] Between a pair of axial end walls 68 of the rubber fitting portion 65 in the axial direction, a boss body portion 70 having a substantially cylindrical shape is formed. A body portion outer peripheral surface 70S is formed on the outer periphery of the boss body portion 70, which faces the feed rubber 62 in the radial direction along the arc shape of the feed roller 42 and abuts against a body portion inner peripheral surface 78Si (described later). In addition, two body portion grooves 70g are formed on the outer periphery of the boss body portion 70, which are recessed from the body portion outer peripheral surface 70S toward the inner periphery, and are aligned with the boss outer peripheral grooves 67g in the axial direction, from one end to the other end in the circumferential direction of the boss body portion 70. Therefore, the outer periphery of the boss body portion 70 has an uneven shape along the axial direction.

[0048] [1-4-1-4. Positioning hole configuration] Positioning holes 72 recessed inwardly from the body groove 70g are formed on one and the other circumferential ends of the boss body 70. When viewed in the axial direction, two positioning holes 72 are disposed on the outer circumferential side of the rotation axis Ax, at positions that are the same radial distance from the rotation axis Ax.

[0049] The positioning hole 72 has a generally cylindrical shape surrounded by a positioning hole inner wall surface 72S having a generally circular cross section with a portion open on the feed rubber 62 side (outer circumferential direction side) relative to the rotation axis Ax in a region between the axial movement restricting surfaces 68Si on both sides in the axial direction. A fitting protrusion 80 (described later) of the feed rubber 62 is inserted into the positioning hole 72. Therefore, the feed boss 60 is surrounded by the positioning hole inner wall surface 72S so as to abut on most of the outer circumferential surface of the fitting protrusion 80 of the feed rubber 62, except for a portion on the feed rubber 62 side relative to the rotation axis Ax.

[0050] Specifically, the positioning hole inner wall surface 72S is a circular shape with a positioning hole opening 72A that is open over a rotation angle range of about 90° at least on the outer circumferential side (feed rubber 62 side) of the center of the circular shape when viewed along the outer circumferential direction of the rotary shaft rubber central part, which is a direction from the rotary shaft Ax toward the central part of the circumferential direction of the feed rubber 62. Therefore, the positioning hole inner wall surface 72S is a circular shape with a cross section that is formed from the rotary shaft Ax side of the circular shape to at least the feed rubber 62 side of the circular shape when viewed along the outer circumferential direction of the rotary shaft rubber central part.

[0051] Therefore, when viewed along the outer circumferential direction of the central portion of the rubber shaft on the inner wall surface 72S of the positioning hole, a retaining portion 72Ss is formed on the feed rubber 62 side from the center of the circle so as to protrude toward each other along the circumferential direction across the positioning hole opening 72A. Therefore, the feed boss 60 is disposed so that the retaining portion 72Ss abuts against the fitting protrusion 80 of the feed rubber 62 on the outer circumferential direction side of the central portion of the rubber shaft.

[0052] As a result, the feed boss 60 restricts the movement of the fitting protrusion 80 toward the outer periphery of the central part of the rotating shaft rubber by the positioning hole 72, preventing the fitting protrusion 80 from coming out of the positioning hole 72 toward the outer periphery of the central part of the rotating shaft rubber.

[0053] Therefore, the feed boss 60 restricts the movement of the feed rubber 62 toward the outer periphery of the central part of the rotating shaft rubber relative to the feed boss 60, and prevents the feed rubber 62 from coming off the feed boss 60 in the outer periphery of the central part of the rotating shaft rubber.

[0054] On the other hand, the positioning hole 72 penetrates the inside of the feed boss 60 so as to extend continuously along the axial direction from one axial end wall outer surface 68So to the other axial end wall outer surface 68So. Therefore, at the place where the positioning hole 72 penetrates the axial end wall 68, a cylindrical axial end wall hole portion 68H surrounded by a circular axial end wall hole portion inner wall surface 68HS is formed. The fitting protrusion both ends 80e (described later), which are both axial ends of the fitting protrusion 80 of the feed rubber 62, are inserted into this axial end wall hole portion 68H. Therefore, the feed boss 60 surrounds the outer peripheral surfaces of the fitting protrusion both ends 80e of the feed rubber 62 so as to abut against the axial end wall hole portion inner wall surface 68HS. As a result, the feed boss 60 restricts the movement of the fitting protrusion 80 in a direction perpendicular to the axial direction, and prevents the fitting protrusion 80 from coming off the axial end wall hole portion 68H in a direction perpendicular to the axial direction.

[0055] [1-4-2. Composition of feed rubber] The feed rubber 62 has a shape that generally follows the arc shape of the outer periphery of the feed roller 42 , and is fitted into a rubber fitting portion 65 in the feed boss 60 .

[0056] [1-4-2-1. Outer periphery configuration] Two rubber outer peripheral grooves 75g are formed on the outer periphery of the feed rubber 62 from one end to the other end in the circumferential direction, which are recessed from the rubber outer peripheral surface 74 in the inner circumferential direction, in alignment with the boss outer peripheral groove 67g of the feed boss 60 in the axial direction. Therefore, three rubber outer peripheral protrusions 75p are formed on the outer periphery of the feed rubber 62 from one end to the other end in the circumferential direction, which are shaped to conform to the arc shape of the feed roller 42, protrude from the outer peripheral surface of the rubber outer peripheral groove 75g in the outer circumferential direction, and have a predetermined radial thickness. The rubber outer peripheral protrusions 75p protrude in the outer circumferential direction beyond the end of the axial end wall 68 on the outer circumferential side. The end face of the rubber outer peripheral protrusions 75p facing the boss outer peripheral protrusions 67p of the feed boss 60 in the circumferential direction is the outer peripheral protrusion outer end face 75Sc. The outer peripheral protrusion outer end face 75Sc abuts against the outer peripheral protrusion inner end face 67pS of the feed boss 60 in the circumferential direction. Of the three rubber outer peripheral protrusions 75p formed along the axial direction, the rubber outer peripheral protrusions 75p arranged at both axial ends have outer peripheral axial end faces 75Sa. The inner peripheral surface of the rubber outer peripheral protrusion 75p connected to the inner peripheral end of the outer peripheral axial end face 75Sa abuts against the outer peripheral surface of the axial end wall 68.

[0057] [1-4-2-2. Structure of rubber body] A rubber main body 78 having a shape conforming to the arc shape of the feed roller 42 and a predetermined radial thickness is formed on the inner peripheral side of the rubber outer peripheral protrusion 75p. A main body inner peripheral surface 78Si is formed on the inner peripheral portion of the rubber main body 78, which faces the feed boss 60 in the radial direction along the arc shape of the feed roller 42 and abuts against the main body outer peripheral surface 70S. In addition, two main body protrusions 78s are formed on the inner peripheral portion of the rubber main body 78, which protrude from the main body inner peripheral surface 78Si in the inner peripheral direction and are aligned with the main body groove 70g of the feed boss 60 in the axial direction, from one end to the other end of the rubber main body 78 in the circumferential direction. Therefore, the inner peripheral portion of the rubber main body 78 has an uneven shape along the axial direction. The feed rubber 62 is positioned in the axial direction relative to the feed boss 60 by fitting the main body protrusions 78s into the main body groove 70g of the feed boss 60.

[0058] The main body axial end faces 78Sa, which are both axial end faces of the rubber main body 78, are located axially inward of the outer peripheral axial end faces 75Sa. Therefore, the feed rubber 62 has a positioning recess 79 that is recessed in an arc shape axially inward from the outer peripheral axial end faces 75Sa on the inner circumferential side of the rubber outer peripheral protrusions 75p, which are the outer peripheral portions at both axial ends. The main body axial end faces 78Sa of the feed rubber 62 are abutted against the axial movement restricting surfaces 68Si of the feed boss 60.

[0059] [1-4-2-3. Configuration of fitting protrusion] On the inner circumferential sides of one end side and the other end side of the rubber main body portion 78 in the circumferential direction, fitting projections 80 are formed which project inwardly beyond the main body portion projection 78s.

[0060] The fitting protrusion 80 has a cylindrical shape with the same axial length from one outer circumferential axial end face 75Sa to the other outer circumferential axial end face 75Sa, and has the same shape and size as the positioning hole 72. The fitting protrusion 80 is inserted into the positioning hole 72 in the feed boss 60. Therefore, in the region between the axial movement restricting surfaces 68Si on both sides in the axial direction, most of the feed rubber 62, except for a portion on the feed rubber 62 side with respect to the rotation axis Ax, on the outer circumferential surface of the fitting protrusion 80, is abutted against and surrounded by the positioning hole inner wall surface 72S of the feed boss 60.

[0061] The fitting protrusion 80 is inserted into the axial end wall hole 68H so that both axial end faces are substantially flush with the axial end wall outer surface 68So. In this manner, the fitting protrusion 80 penetrates the inside of the feed boss 60 from one axial end wall outer surface 68So to the other axial end wall outer surface 68So. For this reason, the entire circumference of the outer circumferential surfaces of the fitting protrusion both ends 80e, which are both axial ends of the fitting protrusion 80, of the feed rubber 62 are abutted against and surrounded by the axial end wall hole inner wall surfaces 68HS of the axial end wall hole 68H of the feed boss 60.

[0062] [1-4-3. Fitting of feed boss and feed rubber] In this configuration, the feed roller 42 is formed by manufacturing the feed boss 60 and the feed rubber 62 separately, and then fitting the feed rubber 62 into the feed boss 60. At this time, the fitting protrusion 80 is distorted in shape so as to bend axially inward, and is deformed so as to become slightly thinner than the positioning hole opening 72A of the positioning hole 72, while the feed rubber 62 is pressed inward toward the feed boss 60, and the fitting protrusion both ends 80e are fitted into the axial end wall hole 68H of the axial end wall 68, and the fitting protrusion 80 is fitted into the positioning hole 72 at a position axially inward of the fitting protrusion both ends 80e, thereby forming the feed roller 42.

[0063] [1-5. What to do if external force is applied to the feed rubber] Next, a description will be given of the resistance force generated in the feed rubber 62 from the feed boss 60 when an external force is applied to the feed rubber 62 from each direction.

[0064] [1-5-1. When radial external force is applied] [1-5-1-1. When external force is applied in the radial outward direction] 7(A) shows a case where an external force Fe is applied to, for example, the central portion of the circumferential direction of the feed rubber 62 along the outer circumferential direction of the central portion of the rotary shaft rubber, in the radially outward direction Dro, which is the direction in which the feed rubber 62 moves away from the feed boss 60. At this time, a resistance force Fr is generated from the retaining portion 72Ss of the feed boss 60 to the fitting protrusion portion 80 of the feed rubber 62 in the opposite direction to the external force Fe in the direction in which the feed rubber 62 moves away from the feed boss 60. Therefore, the feed rubber 62 receives a force that keeps it bonded to the feed boss 60, and is held so that it does not come off the feed boss 60.

[0065] [1-5-1-2. When an external force is applied in the radial inward direction] FIG. 7B shows a case where an external force Fe in the radially inward direction Dri, which is the direction in which the feed rubber 62 is pressed against the feed boss 60, is applied to, for example, the center of the circumferential direction of the feed rubber 62. At this time, a resistance force Fr is generated from the feed boss 60 located on the radially inward direction Dri side of the feed rubber 62 to the feed rubber 62 in the opposite direction to the external force Fe in the direction in which the feed rubber 62 is pressed against the feed boss 60. Note that, although FIG. 7B shows the resistance force Fr applied to the feed rubber 62 from the center of the circumferential direction of the feed boss 60, in reality, the resistance force Fr is also generated against the feed rubber 62 from other points of the feed boss 60 that are in contact with the feed rubber 62. In this way, the feed rubber 62 is pressed against the feed boss 60, and is therefore held so as not to come off the feed boss 60.

[0066] [1-5-2. When an external force is applied in the thrust direction] 8(A) and 8(B) show a case where an external force Fe in the thrust direction Dt is applied to the outer peripheral axial end face 75Sa, which is the end face on one end side of the feed rubber 62 in the thrust direction Dt. Specifically, FIG. 8(A) shows the state as seen in FIG. 4(E), and FIG. 8(B) shows the state as seen in FIG. 4(D). At this time, a resistance force Fr1 in the opposite direction to the external force Fe is generated against the main body axial end face 78Sa of the feed rubber 62 from the axial end wall 68 at the other end side in the thrust direction Dt, which is the opposite side to the one end side where the external force Fe is applied, in the thrust direction Dt of the feed boss 60. Therefore, the feed rubber 62 is held so as not to come off the feed boss 60.

[0067] In addition, when an external force Fe toward the thrust direction Dt is applied to the outer peripheral axial end face 75Sa, which is the end face on one end side of the feed rubber 62 in the thrust direction Dt, the external force Fe is applied at a position away from the fitting protrusion 80 toward the outer peripheral side (radially outward direction Dro), so that a moment of force generates a pull-out force Fu toward the radially outward direction Dro on the fitting protrusion 80, as shown in Fig. 8(B). In response to this, a resistance force Fr2 toward the radially inward direction Dri is generated from the inner wall surface 68HS of the axial end wall hole portion of the feed boss 60 to both ends 80e of the fitting protrusion 80 of the feed rubber 62. Therefore, the feed rubber 62 is held so as not to come off the feed boss 60.

[0068] [1-6. Effects, etc.] In the above configuration, the feed roller 42 is adapted to surround the fitting protrusion 80 extending in the axial direction of the feed rubber 62 with the positioning hole 72 extending in the axial direction of the feed boss 60. Therefore, as shown in Fig. 7(A), even if an external force Fe in the radially outward direction Dro is applied to the feed rubber 62, the feed roller 42 holds the fitting protrusion 80 with the positioning hole 72 to generate a resistance force Fr, and can prevent the feed rubber 62 from moving in the radially outward direction Dro relative to the feed boss 60.

[0069] Further, the feed roller 42 is configured so that the axial end wall hole portions 68H formed at both axial ends of the feed boss 60 surround the fitting protrusion end portions 80e, which are both ends of the fitting protrusion portion 80 extending in the axial direction of the feed rubber 62. Therefore, as shown in Fig. 8(B), even if a pull-out force Fu is generated when an external force Fe in the thrust direction Dt is applied to the feed rubber 62, the feed roller 42 holds the fitting protrusion end portions 80e of the fitting protrusion portion 80 with the axial end wall hole inner wall surface 68HS, generating a resistance force Fr2, and preventing the feed rubber 62 from moving in the radial outward direction Dro relative to the feed boss 60.

[0070] Furthermore, the feed roller 42 is configured to axially pinch the main body axial end face 78Sa of the feed rubber 62 with the axial movement restricting surface 68Si of the axial end wall 68 of the feed boss 60. Therefore, as shown in Fig. 8(A), even if an external force Fe in the thrust direction Dt is applied to the feed rubber 62, the feed roller 42 holds the main body axial end face 78Sa with the axial end wall 68 to generate a resistance force Fr1, thereby preventing movement of the feed rubber 62 in the thrust direction Dt relative to the feed boss 60.

[0071] In this way, the feed roller 42 can prevent the feed rubber 62 from moving in the radial outward direction Dro relative to the feed boss 60 by the positioning holes 72, and can also prevent the feed rubber 62 from moving in the thrust direction Dt relative to the feed boss 60 by the axial end walls 68. This allows the feed roller 42 to prevent the position of the feed rubber 62 relative to the feed boss 60 from changing, and prevents the feed rubber 62 from coming off the feed boss 60. Thus, the feed roller 42 can improve the bonding between the feed boss 60 and the feed rubber 62.

[0072] Furthermore, the feed roller 42 can bond the feed boss 60 and the feed rubber 62 without using adhesive, and generate resistance forces Fr, Fr1, and Fr2 that oppose the external force Fe, simply by modifying the shapes of the feed boss 60 and the feed rubber 62. This makes it possible for the feed roller 42 to dispense with the use of adhesive.

[0073] Furthermore, the feed roller 42 is formed with two sets of positioning holes 72 and fitting protrusions 80. Therefore, the feed roller 42 can firmly join the feed rubber 62 to the feed boss 60, compared to when only one set of positioning holes 72 and fitting protrusions 80 is formed.

[0074] Furthermore, the feed roller 42 has two sets of positioning holes 72 and fitting protrusions 80 arranged at positions that are the same radial distance from the rotation axis Ax on one end side and the other end side in the circumferential direction of the feed rubber 62. Therefore, when an external force Fe toward the radially outward direction Dro is applied to the feed rubber 62, the feed roller 42 can generate a resistance force Fr in a well-balanced manner by each set of positioning holes 72 and fitting protrusions 80.

[0075] Furthermore, in the feed roller 42, the positioning hole 72 is continuously formed from one end side to the other end side in the axial direction of the feed boss 60, and the fitting protrusion 80 is continuously inserted from one end side to the other end side of the positioning hole 72 in the axial direction. Therefore, the feed roller 42 can firmly join the feed rubber 62 to the feed boss 60, compared to a case in which the fitting protrusion 80 is inserted into the positioning hole 72 only partially from one end side to the other end side in the axial direction of the positioning hole 72.

[0076] According to the above-mentioned configuration, the stacking and feeding device 30 includes a transport path 48 connected to the banknote stacking space 40 as a paper sheet storage space for storing banknotes BL as paper sheets, a feed roller 42 provided at a connection point between the banknote stacking space 40 and the transport path 48 and feeding out the banknotes BL from the banknote stacking space 40 to the transport path 48, an opposing roller 44 disposed opposite the feed roller 42 across the transport path 48 and forming an intake port for the banknotes BL between itself and the feed roller 42, a stage 50 movable within the banknote stacking space 40 for stacking the banknotes BL, and a banknote stacking device 50 for stacking the banknotes BL stacked on the stage 50. and a picker roller 52 which contacts the feed rubber 62 and sends out the banknote BL to the intake port, and the feed roller 42 has a feed rubber 62 on the inner circumferential side thereof with an axially extending fitting protrusion 80, a positioning hole 72 as a radial movement restricting hole which extends axially on the outer circumferential side of the rotation axis Ax and into which the fitting protrusion 80 fits to surround at least a part of the fitting protrusion 80, and a feed boss 60 on which an axial end wall 68 as an axial movement restricting part which abuts against one axial side and the other axial side of the feed rubber 62 is formed.

[0077] As a result, the accumulation and feeding device 30 can prevent the feed rubber 62 from moving in the radial outward direction Dro relative to the feed boss 60 by the positioning hole 72, and can prevent the feed rubber 62 from moving in the thrust direction Dt relative to the feed boss 60 by the axial end wall 68.

[0078] 2. Second embodiment [2-1. Configuration of the banknote deposit / withdrawal device] As shown in FIG. 1, the banknote deposit and withdrawal device 101 according to the second embodiment differs from the banknote deposit and withdrawal device 1 according to the first embodiment in that it has a accumulating and dispensing device 120 instead of the accumulating and dispensing device 20, and a accumulating and dispensing device 130 (130A, 130B, and 130C) instead of the accumulating and dispensing device 30 (30A, 30B, and 30C), but is otherwise configured similarly. As in the first embodiment, the accumulating and dispensing devices 130A, 130B, and 130C have the same configuration, and the accumulating and dispensing device 120 has approximately the same configuration as the accumulating and dispensing device 130. Hereinafter, as in the first embodiment, the configuration of the accumulating and dispensing device 130A provided in the banknote storage vault 12A will be described.

[0079] [2-2. Configuration of the accumulation and feeding device] As shown in Figures 2 and 3, the accumulation and feeding device 130A according to the second embodiment differs from the accumulation and feeding device 30A according to the first embodiment in that it has a feed roller 142 instead of the feed roller 42, but is otherwise configured in the same manner.

[0080] [2-3. Feed roller configuration] As shown in Figures 9, 10 and 11, in which the same symbols are used for parts corresponding to those in Figures 4, 5 and 6, the feed roller 142 according to the second embodiment differs from the feed roller 42 according to the first embodiment in that it has a feed boss 160 instead of the feed boss 60 and a feed rubber 162 instead of the feed rubber 62, but is otherwise configured in the same way.

[0081] [2-3-1. Feed boss configuration] The feed boss 160 according to the second embodiment differs from the feed boss 60 according to the first embodiment in that the main body groove portion 70g is omitted and the positioning hole 72 does not penetrate the axial end wall 68 but is formed only in the area between the axial movement limiting surfaces 68Si on both sides in the axial direction, thereby omitting the axial end wall hole portion 68H, but is otherwise configured in the same manner.

[0082] [2-3-2. Feed rubber composition] The feed rubber 162 according to the second embodiment is different from the feed rubber 62 according to the first embodiment in that the main body protrusion 78s is omitted, and the positioning recess 79 is omitted, so that the main body axial end face 78Sa does not exist, and the axial end faces of the feed rubber 162 are flush from the outer peripheral axial end face 75Sa to the axial end face of the fitting protrusion 80, but is otherwise configured in the same manner. Also, the feed rubber 162 is slightly shorter in axial length than the feed rubber 62.

[0083] [2-3-3. Fitting of feed boss and feed rubber] In this configuration, the feed roller 142 is formed by manufacturing the feed boss 160 and the feed rubber 162 separately, and then fitting the feed rubber 162 into the feed boss 160. At this time, the fitting protrusion 80 is deformed so that its thickness becomes slightly thinner than the positioning hole opening 72A of the positioning hole 72, while the feed rubber 162 is pressed inward toward the feed boss 160, and the fitting protrusion 80 is fitted into the positioning hole 72, thereby forming the feed roller 142.

[0084] [2-4. What to do if external force is applied to the feed rubber] Next, a description will be given of the resistance force generated in the feed rubber 162 from the feed boss 160 when an external force is applied to the feed rubber 162 from each direction.

[0085] [2-4-1. When radial external force is applied] [2-4-1-1. When an external force is applied in the radial outward direction] 12(A) shows a case where an external force Fe is applied to, for example, the center of the circumferential direction of the feed rubber 162 along the outer circumferential direction of the central part of the rotary shaft rubber, in the radially outward direction Dro, which is the direction in which the feed rubber 162 moves away from the feed boss 160. At this time, a resistance force Fr is generated from the retaining portion 72Ss of the feed boss 160 to the fitting protrusion portion 80 of the feed rubber 162, in the opposite direction to the external force Fe in the direction in which the feed rubber 162 moves away from the feed boss 160. Therefore, the force that keeps the feed rubber 162 bonded to the feed boss 160 is maintained so that it does not come off the feed boss 160.

[0086] [2-4-1-2. When an external force is applied in the radial inward direction] FIG. 12B shows a case where an external force Fe toward the radial inside direction Dri, which is a direction in which the feed rubber 162 is pressed against the feed boss 160, is applied to, for example, the center part of the circumferential direction of the feed rubber 162. At this time, a resistance force Fr is generated from the feed boss 160 located on the radial inside direction Dri side of the feed rubber 162 to the feed rubber 162 in the opposite direction to the external force Fe toward the direction in which the feed rubber 162 is pressed against the feed boss 160. Note that, although FIG. 12B illustrates the resistance force Fr applied to the feed rubber 162 from the center part of the circumferential direction of the feed boss 160, in reality, the resistance force Fr is also generated against the feed rubber 162 from other points of the feed boss 160 that are in contact with the feed rubber 162. In this way, the feed rubber 162 is pressed against the feed boss 160, and is therefore held so as not to come off the feed boss 160.

[0087] [2-4-2. When an external force is applied in the thrust direction] 13 shows a case where an external force Fe in the thrust direction Dt is applied to the outer peripheral axial end face 75Sa, which is an end face on one end side in the thrust direction Dt of the feed rubber 162. At this time, a resistance force Fr1 in the opposite direction to the external force Fe is generated on the outer peripheral axial end face 75Sa of the feed rubber 162 on the other end side in the thrust direction Dt of the feed boss 160, which is opposite to the one end side where the external force Fe is applied. Therefore, the feed rubber 162 is held so as not to come off the feed boss 160.

[0088] [2-5. Effects, etc.] Compared to feed roller 42 according to the first embodiment, feed roller 142 omits axial end wall hole 68H and does not insert fitting protrusion 80 into axial end wall hole 68H. Therefore, compared to feed roller 42, feed roller 142 does not need to distort the shape of fitting protrusion 80 so that it bends axially inward when feed rubber 162 is joined to feed boss 160, making assembly easier.

[0089] Furthermore, compared to the feed roller 42, the feed roller 142 omits the main body groove 70g in the feed boss 160 and omits the main body protrusion 78s in the feed rubber 162. Therefore, compared to the feed roller 42, the feed roller 142 can simplify the shapes of the feed boss 160 and the feed rubber 162, making it easier to manufacture.

[0090] In addition, the feed roller 142 according to the second embodiment can achieve the same effects as the feed roller 42 according to the first embodiment.

[0091] 3. Third Embodiment [3-1. Configuration of the banknote deposit / withdrawal device] As shown in FIG. 1, the banknote deposit and withdrawal device 201 according to the third embodiment differs from the banknote deposit and withdrawal device 101 according to the second embodiment in that it has a accumulating and feeding device 220 instead of the accumulating and feeding device 120 and a accumulating and feeding device 230 (230A, 230B, and 230C) instead of the accumulating and feeding device 130 (130A, 130B, and 130C), but is otherwise configured similarly. As in the second embodiment, the accumulating and feeding devices 230A, 230B, and 230C have the same configuration, and the accumulating and feeding device 220 has approximately the same configuration as the accumulating and feeding device 230. Hereinafter, as in the second embodiment, the configuration of the accumulating and feeding device 230A provided in the banknote storage vault 12A will be described.

[0092] [3-2. Configuration of the accumulation and feeding device] As shown in Figures 2 and 3, the accumulation and feeding device 230A of the third embodiment differs from the accumulation and feeding device 130A of the second embodiment in that it has a feed roller 242 instead of the feed roller 142, but is otherwise configured in the same manner.

[0093] [3-3. Feed roller configuration] As shown in FIG. 14, in which the same symbols are used for parts corresponding to those in FIG. 9, the feed roller 242 of the third embodiment differs from the feed roller 142 of the second embodiment in that it has a feed boss 260 instead of the feed boss 160, a feed rubber 262 instead of the feed rubber 162, and has the addition of adhesive 82, but is otherwise configured in the same way.

[0094] [3-3-1. Feed boss configuration] The feed boss 260 according to the third embodiment differs from the feed boss 160 according to the second embodiment in that the axial end wall 68 is omitted, but is otherwise configured in the same manner.

[0095] [3-3-2. Feed rubber composition] The feed rubber 262 according to the third embodiment differs from the feed rubber 162 according to the second embodiment in that it is slightly longer in axial length, but is otherwise configured in the same manner.

[0096] [3-3-3. About adhesives] An adhesive 82 is applied between the circumferential inner end surface 67pS of the outer peripheral protrusion of the feed boss 260 and the circumferential outer end surface 75Sc of the outer peripheral protrusion of the feed rubber 262. The adhesive 82 is also applied between the main body outer peripheral surface 70S of the feed boss 260 and the main body inner peripheral surface 78Si of the feed rubber 262. In this manner, the feed rubber 262 is joined to the feed boss 260 by the retaining portion 72Ss of the positioning hole 72 as in the first and second embodiments, and is also joined to the feed boss 260 by the adhesive 82.

[0097] [3-3-4. Fitting of feed boss and feed rubber] In this configuration, the feed roller 242 is formed by manufacturing the feed boss 260 and the feed rubber 262 separately, applying adhesive to the main body inner peripheral surface 78Si and the outer peripheral protrusion circumferential outer end surface 75Sc of the feed rubber 262, and then fitting the feed rubber 162 into the feed boss 160. At this time, the fitting protrusion 80 is deformed so that its thickness becomes slightly thinner than the positioning hole opening 72A of the positioning hole 72, while the feed rubber 262 is pressed inward toward the feed boss 260, and the fitting protrusion 80 is fitted into the positioning hole 72, thereby forming the feed roller 242.

[0098] [3-4. What to do if external force is applied to the feed rubber] Next, a description will be given of the resistance force generated in the feed rubber 262 from the feed boss 260 when an external force is applied to the feed rubber 262 from each direction.

[0099] [3-4-1. When radial external force is applied] [3-4-1-1. When an external force is applied in the radial outward direction] 15(A) shows a case where an external force Fe is applied to, for example, the central portion of the circumferential direction of the feed rubber 262 along the outer circumferential direction of the central portion of the rotary shaft rubber, in the radially outward direction Dro, which is the direction in which the feed rubber 262 moves away from the feed boss 260. At this time, a resistance force Fr is generated from the retaining portion 72Ss of the feed boss 260 to the fitting protrusion portion 80 of the feed rubber 262 in the opposite direction to the external force Fe in the direction in which the feed rubber 262 moves away from the feed boss 260. Therefore, the feed rubber 262 receives a force that keeps it bonded to the feed boss 260, and is held without coming off the feed boss 260.

[0100] [3-4-1-2. When an external force is applied in the radial inward direction] FIG. 15B shows a case where an external force Fe toward the radial inside direction Dri, which is a direction in which the feed rubber 262 is pressed against the feed boss 260, is applied to, for example, the center part of the circumferential direction of the feed rubber 262. At this time, a resistance force Fr is generated from the feed boss 260 located on the radial inside direction Dri side of the feed rubber 262 to the feed rubber 262 in the opposite direction to the external force Fe toward the direction in which the feed rubber 262 is pressed against the feed boss 260. Note that, although FIG. 15B illustrates the resistance force Fr applied to the feed rubber 262 from the center part of the circumferential direction of the feed boss 260, in reality, the resistance force Fr is also generated against the feed rubber 262 from other points of the feed boss 260 that are in contact with the feed rubber 262. In this way, the feed rubber 262 is pressed against the feed boss 260, and is therefore held without coming off the feed boss 260.

[0101] [3-4-2. When an external force is applied in the thrust direction] FIG. 16 shows a case where an external force Fe in the thrust direction Dt is applied to the outer peripheral axial end face 75Sa, which is the end face on one end side of the feed rubber 262 in the thrust direction Dt. Specifically, FIG. 16(A) shows the state when viewed in the state of FIG. 14(C), and FIG. 16(B) shows the state when viewed in the state of FIG. 14(A). At this time, a resistance force Fr1 in the opposite direction to the external force Fe is generated against the main body inner peripheral surface 78Si and the outer peripheral protrusion circumferential outer end face 75Sc of the feed rubber 262 from the main body outer peripheral surface 70S and the outer peripheral protrusion circumferential inner end face 67pS of the feed boss 260 bonded to the adhesive 82 applied to the main body inner peripheral surface 78Si and the outer peripheral protrusion circumferential outer end face 75Sc of the feed rubber 262. Therefore, the feed rubber 262 is held so as not to come off the feed boss 260.

[0102] 16B, when an external force Fe in the thrust direction Dt is applied to the vicinity of the outer peripheral protrusion circumferential outer end face 75Sc of the outer peripheral axial end face 75Sa, which is the end face on one end side of the feed rubber 262 in the thrust direction Dt, a resistance force Fr in the opposite direction to the external force Fe is generated against the outer peripheral protrusion circumferential outer end face 75Sc of the feed rubber 262 from the outer peripheral protrusion circumferential inner end face 67pS of the feed boss 260, which is bonded to the adhesive 82 applied to the outer peripheral protrusion circumferential outer end face 75Sc of the feed rubber 262. Therefore, the feed rubber 262 is held so as not to come off the feed boss 260.

[0103] [3-5. Effects, etc.] According to the above configuration, the feed roller 242 omits the axial end wall 68 in the feed boss 260, and applies the adhesive 82 between the outer peripheral protrusion circumferential inner end face 67pS of the feed boss 260 and the outer peripheral protrusion circumferential outer end face 75Sc of the feed rubber 262, and between the main body outer peripheral surface 70S of the feed boss 260 and the main body inner peripheral surface 78Si of the feed rubber 262. Therefore, even if an external force Fe in the thrust direction Dt is applied to the feed rubber 262, the main body outer peripheral surface 70S and the outer peripheral protrusion circumferential inner end face 67pS to which the adhesive 82 is applied hold the main body inner peripheral surface 78Si and the outer peripheral protrusion circumferential outer end face 75Sc, generating a resistance force Fr1, and preventing the feed rubber 262 from moving in the thrust direction Dt relative to the feed boss 260.

[0104] Furthermore, although the feed roller 242 uses the adhesive 82, the anti-slip portion 72Ss and the fitting protrusion portion 80 can generate a resistance force Fr that counters the external force Fe acting in the radial outward direction Dro on the feed rubber 262. Therefore, even if the adhesive 82 has a weaker adhesive strength than the conventional adhesive 382 (Figure 17), the feed rubber 262 can be stably joined to the feed boss 260.

[0105] Furthermore, in comparison with the feed roller 142, the feed roller 242 omits the axial end wall 68 in the feed boss 260. Therefore, in comparison with the feed roller 142, the feed roller 242 can have a simpler shape for the feed boss 260, which makes it easier to manufacture.

[0106] According to the above-mentioned configuration, the stacking and feeding device 230 includes the transport path 48 connected to the banknote stacking space 40 that stores the banknotes BL, a feed roller 242 that is provided at the connection point between the banknote stacking space 40 and the transport path 48 and feeds out the banknotes BL from the banknote stacking space 40 to the transport path 48, an opposing roller 44 that is disposed opposite the feed roller 42 across the transport path 48 and forms an intake port for the banknotes BL between itself and the feed roller 42, a stage 50 that is movable within the banknote stacking space 40 and stacks the banknotes BL, and a counter roller 44 that comes into contact with the banknotes BL stacked on the stage 50 to take in the banknotes BL. The feed roller 242 is provided with a picker roller 52 which sends the feed rubber 262 to the feed opening, and the feed roller 242 has a feed rubber 262 with an axially extending fitting protrusion 80 formed on the inner peripheral side, a feed boss 260 with a positioning hole 72 formed therein which extends axially on the outer peripheral side of the rotation axis Ax and into which the fitting protrusion 80 fits and surrounds at least a part of the fitting protrusion 80, and an adhesive 82 arranged on at least a part of the contact surface between the feed rubber 262 and the feed boss 260 to join the feed rubber 262 and the feed boss 260.

[0107] As a result, the accumulation and feeding device 230 can prevent the feed rubber 262 from moving in the radial outward direction Dro relative to the feed boss 260 by the positioning hole 72, and can prevent the feed rubber 262 from moving in the thrust direction Dt relative to the feed boss 260 by the adhesive 82.

[0108] In addition, the feed roller 242 according to the third embodiment can achieve the same effects as the feed roller 142 according to the second embodiment.

[0109] [4. Other embodiments] In the above-described first embodiment, the feed boss 60 and the feed rubber 62 are manufactured separately, and the feed roller 42 is formed by fitting the feed rubber 62 into the feed boss 60. However, the present invention is not limited to this, and the feed boss 60 and the feed rubber 62 may be integrally formed. The same applies to the second and third embodiments.

[0110] In the above-described first embodiment, two sets of positioning holes 72 and fitting protrusions 80 are arranged around the rotation axis Ax. The present invention is not limited to this, and any number of sets of positioning holes 72 and fitting protrusions 80, three or more, may be arranged. Furthermore, only one set of positioning holes 72 and fitting protrusions 80 may be arranged as long as a bonding strength sufficient to prevent the feed rubber 62 from coming off the feed boss 60 when a force is applied in the radially outward direction Dro can be ensured. The same applies to the second and third embodiments.

[0111] Furthermore, in the above-mentioned first embodiment, the positioning hole 72 is continuously formed from one end side to the other end side in the axial direction of the feed boss 60.

Even in this case, the movement of the fitting protrusion 80 in the direction perpendicular to the axial direction can be restricted by the axial end wall hole inner wall surface 68HS, so that the feed rubber 62 can be prevented from coming off the feed boss 60 even if a removal force Fu in the radial outward direction Dro is generated in the fitting protrusion 80.

[0113] Furthermore, the axial end wall hole portion 68H may be formed at a location other than on the extension line of the positioning hole 72, and a protrusion that is inserted into the axial end wall hole portion 68H may be formed from a location other than the fitting protrusion portion 80 on the feed rubber 62.

[0114] Furthermore, in the above-mentioned first embodiment, the positioning hole 72 and the fitting protrusion 80 are described as being cylindrical in shape along the axial direction. The present invention is not limited to this, and the positioning hole 72 and the fitting protrusion 80 may be various other shapes, such as a triangular prism shape, a rectangular prism shape, or a pentagonal prism shape along the axial direction. In short, by forming the retaining portion 72Ss in the positioning hole 72 on the outer circumferential side of the fitting protrusion 80, the retaining portion 72Ss may surround at least a part of the outer circumferential side of the fitting protrusion 80, and restrict the movement of the fitting protrusion 80 toward the outer circumferential side. The same applies to the second and third embodiments.

[0115] Furthermore, in the above-mentioned first embodiment, a description has been given of a case in which the positioning hole 72 is formed in the feed boss 60 and the fitting projection 80 is formed in the feed rubber 62. The present invention is not limited to this, and the arrangement may be reversed, with the fitting projection 80 formed in the feed boss 60 and the positioning hole 72 in the feed rubber 62. The same applies to the second and third embodiments.

[0116] Furthermore, in the first embodiment described above, similarly to the third embodiment, adhesive 82 may be applied to various locations where the feed boss 60 and the feed rubber 62 come into contact with each other. The same applies to the second embodiment.

[0117] Furthermore, in the above-mentioned first embodiment, the feed boss 60 is made of resin or metal, and the feed rubber 62 is made of rubber. The present invention is not limited to this, and the feed boss 60 may be made of various other low-friction materials that do not generate a force for feeding the banknotes BL, and the feed rubber 62 may be made of various other high-friction materials that generate a force for feeding the banknotes BL. The same applies to the second and third embodiments.

[0118] Furthermore, in the second embodiment described above, similarly to the first embodiment, the boss outer circumferential groove portion 67g may be formed in the feed boss 160, and the main body portion protrusion portion 78s may be formed in the feed rubber 162, respectively.

[0119] Furthermore, in the above-mentioned third embodiment, the case where the adhesive 82 is applied to the main body inner circumferential surface 78Si and the outer peripheral protrusion circumferential outer end surface 75Sc has been described. The present invention is not limited to this, and it is also possible to omit a part of the adhesive 82, not apply the adhesive 82 to the main body inner circumferential surface 78Si and the outer peripheral protrusion circumferential outer end surface 75Sc, and apply the adhesive 82 to an area other than the main body inner circumferential surface 78Si and the outer peripheral protrusion circumferential outer end surface 75Sc where the feed boss 260 and the feed rubber 262 come into contact, or apply the adhesive 82 to an area other than the main body inner circumferential surface 78Si and the outer peripheral protrusion circumferential outer end surface 75Sc where the feed boss 260 and the feed rubber 262 come into contact, in addition to the main body inner circumferential surface 78Si and the outer peripheral protrusion circumferential outer end surface 75Sc.

[0120] Furthermore, in the above-described third embodiment, the feed boss 260 and the feed rubber 262 are bonded to each other by the adhesive 82. The present invention is not limited to this, and the feed boss 260 and the feed rubber 262 may be bonded to each other by various other bonding members, such as double-sided tape.

[0121] Furthermore, in the third embodiment described above, the feed rubber 262 is fitted to the feed boss 260 by pushing the feed rubber 262 inwardly relative to the feed boss 260. However, the present invention is not limited to this, and the feed rubber 262 may be fitted to the feed boss 260 by sliding it in the axial direction.

[0122] Furthermore, in the above-mentioned embodiment, the present invention has been described as being applied to the feed rollers 42, 142, or 242. However, the present invention is not limited to this, and may be applied to various other rollers.
