Abstract

PROBLEM TO BE SOLVED: To separate accumulated media with high accuracy.SOLUTION: In a separation portion 25 of a bank bill cassette 17, a first gate G1 is formed between a feed roller 32 and a first gate roller 52, and a second gate G2 is formed between the feed roller 32 and a second gate roller 62. Even when an uppermost bank bill BL1 and a second bank bill BL2 are allowed, in a first gate G1, to pass through the first gate G1 because of a large friction force N2 between the uppermost bank bill BL1 and the second bank bill BL2, the separation portion 25 can cause the second gate roller 62 to apply an additional friction force N4 in the second gate G2 while causing the first gate roller 52 to still apply a friction force N3. The bank bill cassette 17 thus allows inhibiting approach of the second bank bill BL2 in the second gate G2 and carrying separately the bank bill BL1 on the uppermost surface alone.

Description

  The present invention relates to a medium separating apparatus and a medium processing apparatus, and is suitable for application to an automatic teller machine (ATM) or the like that performs a desired transaction by inserting a paper-like medium such as a banknote.

  2. Description of the Related Art Conventionally, in an automatic teller machine used in a financial institution or the like, for example, a customer deposits cash such as banknotes or coins according to transaction details with a customer, and also withdraws cash to a customer. ing.

  As an automatic teller machine, for example, a banknote deposit / withdrawal port for transferring banknotes to / from customers, a transport unit for transporting banknotes inside, and a denomination, authenticity, and damage etc. of inserted banknotes are distinguished. There are some which have a discriminating part which performs, a temporary storage part which temporarily holds the inserted bill, and a bill cassette which stores a bill for every denomination.

  This automatic teller machine pays out banknotes according to the amount of money to be withdrawn from the banknote cassette and transports it by the transport unit when the amount to be withdrawn is determined by the customer's operation instruction in the withdrawal process. After discriminating that normal bills have been fed out without excess or deficiency, the bills are conveyed to the bill deposit / withdrawal port and taken out by the customer.

  In this banknote cassette, for example, banknotes are stored in an internal stacking space in a state in which the paper surfaces of the banknotes are stacked up and down, and the banknotes are stacked by a separating unit disposed above the stacking space when the banknotes are fed out. Some of them are separated so as to peel off the uppermost banknote and fed out one by one (for example, see Patent Document 1).

  For example, as shown in FIGS. 21, 22, 23, and 24, the conventional separation unit 325 is provided above the stage 23 and has two feed shafts 31 disposed along the left-right direction. The roller 32 is penetrated at a predetermined interval.

  The feed roller 32 is made of a material having a relatively small friction coefficient with respect to the banknote BL. Further, a high friction portion 32R is provided on a part of the outer periphery of the feed roller 32 (FIG. 24). The high friction portion 32R has an increased frictional force against the bill BL.

  Four picker rollers 37 are arranged in front of the feed roller 32 at a position almost directly above the stage 23. The picker roller 37 is configured to rotate in synchronization with the feed roller 32.

  A part of the outer periphery of the picker roller 37 is provided with a high friction part 37R that protrudes outward from the other part (FIG. 24). The high friction part 37R has an increased frictional force on the bills BL, like the high friction part 32R.

  A gate roller 52 is provided below the feed roller 32. The position of the gate roller 52 is adjusted so that a gap corresponding to one bill BL is formed between the gate roller 52 and the feed roller 32. Hereinafter, this gap and its peripheral part are referred to as a gate G1.

  On the other hand, the stage 23 is moved in the vertical direction by a drive mechanism (not shown). Moreover, the stage 23 forms the accumulation | stacking banknote BLS as shown in FIG. 25, when banknote BL is integrated | stacked on an upper surface.

  When the banknote cassette is fed, the stage 23 is moved upward to bring the uppermost banknote BL1 out of the stacked banknotes BLS into contact with the picker roller 37 of the separation unit 325 (FIG. 25), and the feed roller 32 and The picker roller 37 is rotated counterclockwise while the gate roller 52 is stationary.

  The picker roller 37 applies a backward force to the uppermost banknote BL1, and causes its tip to enter the gate G1. At this time, the second and lower banknotes BL from the top of the stacked banknotes BLS may be moved backward by being pulled by the uppermost banknote BL1 due to the frictional force between the banknotes BL.

  On the other hand, the gate roller 32 of the separation unit 325 is stationary without rotating, so that the second and lower banknotes BL from the top of the stacked banknotes BLS are damped as shown in FIG. Only BL1 enters the gate G1. Thereby, the separation unit 325 can separate the uppermost banknote BL1 from the stacked banknote BLS one by one.

JP2012-076914 (FIG. 1)

  However, the frictional force between the banknotes BL in the stacked banknotes BLS varies depending on the influence of static electricity, humidity, etc., the deterioration state of the banknotes BL, and the like.

  For this reason, in the separation unit 325, for example, as shown in FIG. 27 corresponding to FIG. 26, two or more banknotes may enter the gate G1, and the banknote BL may not be separated one by one. There was a problem.

  The present invention has been made in consideration of the above points, and an object of the present invention is to propose a medium separating apparatus and a medium processing apparatus capable of accurately separating an accumulated medium.

  In order to solve such a problem, in the medium separation device of the present invention, a pressing unit that presses the stacked medium in which the sheet-shaped medium is stacked with the surfaces facing each other in a predetermined pressing direction, and the pressing unit on the pressing direction side of the pressing unit. A feeding unit that applies force in a pushing direction that intersects the pressing direction to the surface on the pressing direction side of the accumulation medium, and a feed rotation axis that is perpendicular to the pushing direction and the pushing direction. A high friction part with increased frictional force against the medium is provided on at least a part of the peripheral side part, and a part of the peripheral side part is exposed to a transport path to transport the medium, and a predetermined centering on the feed rotation axis Friction by the high friction part against the feed roller that rotates in the direction of rotation of the feed roller and the medium that advances in contact with the peripheral side of the feed roller as the feed roller rotates in the direction of rotation of the feed roller in the conveyance path Power A first restricting portion that applies a lower first frictional force, and abutting on the peripheral side portion of the feed roller as the feed roller rotates in the direction of rotation of the feed roller in the conveying path. And a second restricting portion for applying a second frictional force lower than the frictional force due to the high frictional portion to the medium after the first frictional force is applied by the portion.

  Further, in the medium processing apparatus of the present invention, there are provided a pressing unit that presses the stacked medium in which the sheet-shaped media are stacked with their surfaces facing each other in a predetermined pressing direction, and a pressing direction side of the pressing unit. A pushing portion that applies a force to the pushing direction that intersects the pushing direction with respect to the surface on the pushing direction side, and a circumferential side portion that is centered on the feed rotation axis along the orthogonal direction perpendicular to the pushing direction and the pushing direction. A high friction part with increased frictional force against the medium is provided in at least a part, and a part of the peripheral side part is exposed to the conveyance path where the medium is to be conveyed, and in a predetermined rotation direction around the feed rotation axis. The rotating feed roller and the medium that advances in contact with the circumferential side portion of the feed roller in the conveyance path in the conveyance path, and has a lower frictional force than the high friction portion. 1 frictional force In the conveying path, the first restricting portion to be actuated advances in contact with the peripheral side portion of the feed roller as the feed roller rotates in the operation rotation direction, and a first frictional force acts by the first restricting portion. A second regulating unit that applies a second frictional force that is lower than the frictional force generated by the high frictional unit to the medium after being formed, and a conveyance unit that conveys the medium separated from the accumulation medium and conveyed along the conveyance path, It was made to provide.

  As a result, the present invention has a high frictional force between the uppermost medium and the second medium of the accumulated medium, and the two media overlap and convey along the conveyance path by the action of the high friction part of the feed roller. In this case, even if the first frictional force between the first restricting part and the second medium is weaker than the frictional force between the media and the two cannot be separated, the second restricting part By further applying the second frictional force to the medium, it is possible to separate both of them and advance only the uppermost medium.

  According to the present invention, the frictional force between the uppermost medium and the second medium of the accumulated medium is high, and the two media overlap and convey along the conveyance path by the action of the high friction portion of the feed roller. In this case, even if the first frictional force between the first restricting part and the second medium is weaker than the frictional force between the media and the two cannot be separated, the second restricting part By further applying the second frictional force to the medium, it is possible to separate both of them and advance only the uppermost medium. Thus, the present invention can realize a medium separating apparatus and a medium processing apparatus that can accurately separate the accumulated medium.

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

[1. First Embodiment]
[1-1. Overall configuration of automatic teller machine]
As shown in FIG. 1, an automatic teller machine 1 as a paper sheet processing apparatus is configured around a box-shaped casing 2, and is installed in a financial institution or the like, for example, with a customer. Transactions related to cash such as deposit and withdrawal transactions are conducted.

  The case 2 has a shape in which a part that is easy to insert a bill or operate with a touch panel in a state where the customer faces the front side, that is, a part extending from the upper part of the front surface to the upper surface is cut off, The customer service part 3 is provided in this part.

  The customer service section 3 directly exchanges cash, bankbook, etc. with the customer, and is also configured to receive transaction information and accept operation instructions. The card entry / exit 4, the passbook entry / exit 5, and the banknote entry / exit A coin opening 6, a coin deposit / withdrawal opening 7, and a display operation unit 8 are provided.

  The card entry / exit 4 is a portion into which various cards such as a cash card are inserted or ejected. A card processing unit (described later) for reading account numbers and the like magnetically recorded on various cards is provided on the back side of the card slot 4.

  The passbook entry / exit 5 is a portion where the passbook is inserted or discharged. On the back side of the bankbook entry / exit 5, a bankbook processing unit (described later) for reading magnetic information recorded in the bankbook, printing transaction contents, and the like is provided.

  The banknote deposit / withdrawal port 6 is a part into which banknotes to be deposited by customers are inserted and banknotes to be dispensed to customers are discharged. The banknote deposit / withdrawal port 6 is opened or closed by driving a shutter.

  The coin deposit / withdrawal port 7 is a portion where a coin to be deposited by the customer is inserted and a coin to be dispensed to the customer is discharged. Similarly to the banknote deposit / withdrawal port 6, the coin deposit / withdrawal port 7 is opened or closed by driving a shutter.

  The display operation unit 8 is a touch panel in which an LCD (Liquid Crystal Display) that displays an operation screen at the time of a transaction and a touch sensor that inputs a transaction type, a password, a transaction amount, and the like are integrated.

  In the following, the front side of the automated teller machine 1 facing the customer is the front side, the opposite is the rear side, the left and right are the left side and the right side as viewed from the customer facing the front side, respectively, and the upper side and the lower side. A side is defined and described.

  In the housing 2, a main control unit 9 that performs overall control of the entire automatic teller machine 1, a banknote depositing and dispensing machine 10 that performs various processes related to the banknote BL, and the like are provided.

  The main control unit 9 is mainly configured by a CPU (Central Processing Unit) (not shown), and by reading and executing a predetermined program from a ROM, a flash memory, etc. (not shown), various transactions such as deposit transactions and withdrawal transactions are performed. It is made to perform the process.

  The main control unit 9 includes a storage unit including a RAM (Random Access Memory), a hard disk drive, a flash memory, and the like, and stores various information in the storage unit.

  As shown in the side view of FIG. 2, the banknote depositing / dispensing machine 10 includes a plurality of parts that perform various processes related to the banknote BL. Moreover, each part of the banknote depositing / withdrawing machine 10 is controlled by the banknote control unit 11.

  The banknote control unit 11 is configured around a CPU (not shown) as in the case of the main control unit 9, and determines a conveyance destination of the banknote BL by reading and executing a predetermined program from a ROM, flash memory, etc. (not shown). Various processing such as processing to perform is performed.

  For example, when a customer performs a deposit transaction in which a banknote is deposited, the banknote controller 11 receives a predetermined operation input via the display operation unit 8 (FIG. 1), and then the shutter of the banknote deposit / withdrawal port 6 (FIG. 1). Is opened to insert the bill into the deposit / withdrawal unit 12.

  When a banknote is inserted into the container 12 </ b> A, the deposit / withdrawal unit 12 closes the shutter of the banknote deposit / withdrawal port 6, takes out banknotes one by one from the container 12 </ b> A, and delivers the banknote to the transport unit 13. The conveyance part 13 advances the banknote comprised by the rectangular paper sheet shape along a transversal direction, and conveys it to the discrimination part 14. FIG.

  The discrimination unit 14 discriminates the denomination and authenticity of the banknote and the degree of damage while conveying the banknote, and notifies the banknote control unit 11 of the discrimination result. In response to this, the banknote control unit 11 determines a transport destination of the banknote based on the acquired discrimination result.

  At this time, the transport unit 13 temporarily holds the banknotes (so-called correct bills) identified as normal in the discrimination unit 14 by transporting them to the temporary storage unit 15, while banknotes identified as not to be traded ( A so-called non-conformity ticket or fake ticket) is conveyed to the deposit / withdrawal unit 12 and returned to the customer.

  Thereafter, the banknote control unit 11 allows the customer to confirm the deposit amount via the display operation unit 8, transports the banknote held in the temporary storage unit 15 to the discrimination unit 14 by the transport unit 13, and determines the denomination and damage. Differentiate the degree, etc., and obtain the result of the discrimination.

  And the banknote control part 11 will convey this to the rejection cassette 16 by the conveyance part 13 as a banknote which should not be reused if the damage degree of a banknote is large, and will reuse this if the degree of damage is small. It is made to convey by the conveyance part 13 as a banknote which should be accommodated in the banknote cassette 17 according to the money type.

  Moreover, the banknote control part 11 respond | corresponds to the money to withdraw, after receiving predetermined operation input via the display operation part 8 (FIG. 1), for example, when a customer performs withdrawal transaction which withdraws banknote BL. The bill BL is fed out from the bill cassette 17 and conveyed to the discrimination unit 14 by the conveyance unit 13.

  Subsequently, the bill control unit 11 discriminates the bill BL by the discrimination unit 14 and then conveys the bill BL to the deposit / withdrawal unit 12, and opens the shutter of the bill deposit / withdrawal port 6 (FIG. 1) to allow the customer to take out.

  In this way, the banknote cassette 17 takes in and stores the banknotes BL transported by the transport section 13 and also feeds out the banknotes BL from the inside and delivers them to the transport section 13.

[1-2. Bill cassette structure]
As schematically shown in FIG. 3, the banknote cassette 17 is configured to take in and accumulate banknotes BL as a medium in a rectangular parallelepiped casing 21. FIG. 3 shows a right side view. Further, for convenience of explanation, some parts are transmitted or omitted.

  The casing 21 substantially closes the front, back, left, and right side surfaces, and protects the bills BL, components, and the like accumulated therein. A uniform flat front door 22 is provided on the front side of the housing 21.

  A rectangular parallelepiped internal space 21 </ b> S is formed in the housing 21. A flat plate-like stage 23 is provided in the internal space 21S. The stage 23 has a plate surface substantially horizontal, divides the internal space 21S into upper and lower parts, and uses the upper side thereof as an accumulation space CS to accumulate banknotes BL on the upper surface of the stage 23, thereby collecting banknotes BLS as an accumulation medium. And

  The stage 23 is moved up and down by a stage drive mechanism (not shown). Further, a level difference is formed in the upper surface of the stage 23 at a certain distance from the left and right ends so that the center side is high and the left and right ends are low.

  A separating portion 25 is provided in a rear portion on the upper side of the housing 21. The separation unit 25 is configured to operate in two types of operation modes such as a discharge mode and a separation mode.

  The release mode is an operation mode in which when the banknotes BL transported by the transport unit 13 are stacked in the banknote cassette 17, the banknotes BL are transported downward and discharged into the stacking space CS. On the other hand, the separation mode is an operation mode in which when the banknotes BL in the banknote cassette 17 are fed out and delivered to the transport unit 13, the banknotes BL are separated from the stacked banknotes BLS one by one and transported upward.

  For example, the banknote cassette 17 operates the separating unit 25 in the discharge mode when storing the banknote BL therein. At this time, the separating unit 25 transports the bill BL transported from the transport unit 13 downward or forward along the transport path W, and discharges the bill BL forward from the vicinity of the upper end on the rear surface side of the accumulation space CS. .

  A bill stopper 26 is provided in the vicinity of the upper end on the front side of the accumulation space CS, that is, on the upper side of the rear surface of the front door 22 via an elastic body (not shown). The bill stopper 26 is formed in a small rectangular parallelepiped shape. When the banknote BL released from the separating unit 25 collides, the bill stopper 26 absorbs the impact of the banknote BL by the action of the elastic body and slightly pushes it backward.

  Thereafter, the bills BL are knocked down by an impeller (not shown) and stacked on the stage 23 or the stacked bills BLS placed on the stage 23.

  Moreover, the banknote cassette 17 moves the stage 23 upwards when pushing out the internal banknote BL, and presses the stack | stuck banknote BLS against the ceiling surface of the stacking space CS, and operates the isolation | separation part 25 in isolation | separation mode. At this time, the separating unit 25 sequentially separates the uppermost banknotes BL from the stacked banknotes BLS one by one, transports them back or upward along the transport path W, and delivers them to the transport unit 13.

  As described above, the bill cassette 17 is configured to stack and separate the bills BL by operating the separation unit 25 in the discharge mode or the separation mode.

[1-3. Configuration of separation unit]
Next, the configuration of the separation unit 25 will be described with reference to FIGS. 4, 5, 6, 7, and 8. 4 is a perspective view seen from the upper right rear side, FIG. 5 is a rear view, FIG. 6 is a plan view, FIG. 7 is a bottom view, and FIG. 8 is a right side view.

  The separation unit 25 is configured around the feed shaft 31. The feed shaft 31 is formed in an elongated cylindrical shape, and the central axis is directed in the left-right direction. Three feed rollers 32A, 32B, and 32C are passed through the feed shaft 31.

  The feed roller 32C is located substantially at the center of the feed shaft 31. The feed rollers 32A and 32B are located on the right side and the left side of the feed roller 32C, respectively, and are spaced apart from the feed roller 32C by a predetermined distance.

  The feed rollers 32A, 32B, and 32C are all configured similarly. For convenience of explanation, the feed rollers 32A, 32B, and 32C are collectively referred to as a feed roller 32 below.

  The feed roller 32 is formed in a cylindrical shape that is shorter in the left-right direction and larger in diameter than the feed shaft 31. As shown in FIGS. 5, 6, and 7, two groove portions 32 </ b> X along the circumferential direction are formed on the peripheral side surface of the feed roller 32, and the remaining portions become three ridge portions 32 </ b> Y. ing.

  Further, the feed roller 32 is made of a resin material having a relatively small friction coefficient, and the surface of the ridge portion 32Y is smoothly finished, so that it hardly slips against the bills BL and easily slides. Has been made.

  Further, as shown in FIG. 8, the feed roller 32 has a high friction portion at a part of the outer peripheral portion of the ridge portion 32 </ b> Y, specifically, within the range of the angle θ when viewed from the center point P <b> 3 of the feed shaft 31 and the feed roller 32. 32R is provided.

  The high friction portion 32R is made of a material having a relatively large friction coefficient, such as rubber, and has a higher frictional force on the bill BL than the other portions of the feed roller 32.

  The feed shaft 31 has a sub-feed roller 33 penetrating through the right side of the feed roller 32A and the left side of the feed roller 32B. Each sub-feed roller 33 is configured in a flat cylindrical shape having a radius substantially the same as that of the feed roller 32 and having a shorter axial length than the feed roller 32.

  The sub-feed roller 33 is in contact with the bill BL over a relatively wide area, thereby transmitting a relatively large driving force to the bill BL, thereby conveying the bill BL.

  Further, a pulley 34 is passed through the feed shaft 31 outside the left and right sub-feed rollers 33. The pulley 34 is formed in a relatively small cylindrical shape having a slightly larger radius than the feed shaft 31.

  The feed shaft 31 is rotated integrally with the feed rollers 32 (32A, 32B, and 32C), the two sub-feed rollers 33, and the two pulleys 34 by transmitting a driving force from an actuator (not shown). At this time, the feed shaft 31 is rotated in the direction of arrow R1 in FIG. 8, that is, clockwise in the discharge mode described above, and is rotated in the direction of arrow R2, ie, counterclockwise in the separation mode.

  Further, brackets 35 are inserted through the feed shaft 31 on the left and right. The bracket 35 is shaped such that the left and right portions are folded backwards, leaving the central portion of the thin plate member elongated in the left-right direction and the front and rear, and an insertion hole is formed in the vicinity of the rear end of the folded portion. It has been drilled.

  The insertion holes of the bracket 35 are inserted in two places on the feed shaft 31, inside the feed roller 32 and outside the pulley 34. Incidentally, the left and right brackets 35 can be freely rotated with respect to the feed shaft 31, that is, the front portion can be displaced up and down.

  Each bracket 35 rotatably supports a picker shaft 36 having a central axis along the left-right direction in front of the feed shaft 31. Each picker shaft 36 is penetrated by two picker rollers 37 at a predetermined interval. Like the feed roller 32, the picker roller 37 is made of a material having a relatively small friction coefficient with respect to the bill BL.

  A part of the outer periphery of the picker roller 37 is provided with a high friction part 37R that protrudes outward from the other part (FIG. 8). The high friction portion 37R is made of a material having a relatively high frictional force, such as rubber, like the high frictional portion 32R of the feed roller 32. The frictional force on the bill BL is higher than that of other portions of the picker roller 37. Has been increased.

  A pulley 38 having the same outer diameter as that of the pulley 34 is passed through a portion of the picker shaft 36 that is in front of the pulley 34. A belt 39 is stretched between the pulley 38 and the pulley 34. The belt 39 travels as the pulley 34 that is integral with the feed shaft 31 rotates, and rotates the pulley 38 and the picker shaft 36. As a result, the picker roller 37 can rotate in synchronization with the feed roller 32 and the sub-feed roller 33.

  A plate-like picker guide 40 is provided below the bracket 35. The picker guide 40 has holes 40H formed at four locations corresponding to the picker roller 37, and a part of the picker roller 37 is exposed downward from the holes.

  A first gate shaft 51 having a central axis along the left-right direction is disposed below the feed shaft 31. The first gate shaft 51 has an outer diameter comparable to that of the feed shaft 31 and is shorter in the axial direction (that is, in the left-right direction) than the feed shaft 31. The first gate shaft 51 is located on the left side from the right end of the right feed roller 32A. The distance is about the same as the distance to the left end of the feed roller 32B.

  The first gate shaft 51 is supported by a support member (not shown) and rotates only in the counterclockwise direction (arrow R2 direction) in FIG. 8 and does not rotate in the opposite direction (arrow R1 direction). It has been incorporated.

  The first gate rollers 52A and 52B are penetrated through the first gate shaft 51 at locations facing the feed rollers 32A and 32B, respectively. The first gate rollers 52A and 52B are similarly configured. For convenience of explanation, the first gate rollers 52A and 52B will be collectively referred to as the first gate roller 52 below.

  The first gate roller 52 is formed in a columnar shape having a smaller diameter than the feed roller 32 and a shorter length in the axial direction (that is, the left-right direction). The first gate roller 52 is made of a resin material or a rubber material having a lower frictional force than the high friction portion 32R of the feed roller 32.

  As shown in FIG. 5, one groove portion 52X along the circumferential direction is formed on the peripheral side surface of the first gate roller 52, and the remaining portion becomes two ridge portions 52Y.

  The first gate roller 52 causes the two ridges 52Y to face the two grooves 32X in the feed roller 32 (FIG. 5), and the tip of the ridge 52Y (ie, the portion closest to the center point P3) It slightly enters the groove 32X. Accordingly, the center ridge 32 </ b> Y of the feed roller 32 slightly enters the groove 52 </ b> X of the first gate roller 52. In other words, the separation unit 25 partially overlaps the outer circumference circle of the first gate roller 52 and the outer circumference circle of the feed roller 32 when viewed from the left-right direction (FIG. 8).

  As a result, a gap is formed between the feed roller 32 and the first gate roller 52 so as to meander alternately on the feed roller 32 side and the first gate roller 52 side along the left-right direction. Hereinafter, the peripheral portion of the gap between the feed roller 32 and the first gate roller 52 is referred to as a first gate G1.

  A second gate shaft 61 having a central axis along the left-right direction is disposed below the feed shaft 31. The second gate shaft 61 has the same outer diameter as that of the feed shaft 31 and the first gate shaft 51, and the axial direction (that is, the left-right direction) is shorter than the first gate shaft 51. It is about the same as the feed roller 32C.

  The second gate shaft 61 is supported by a support member (not shown), and a so-called one-way clutch is incorporated in the same manner as the first gate shaft 51.

  A second gate roller 62 passes through the center of the second gate shaft 61 on the left and right sides, that is, at a position facing the feed roller 32C. Similar to the first gate roller 52, the second gate roller 62 is formed in a cylindrical shape, and one groove 62X along the circumferential direction is formed on the peripheral side surface thereof, and the remaining portion has two ridges. This is part 62Y (FIG. 5).

  Similarly to the first gate roller 52, the second gate roller 62 has the two ridges 52Y opposed to the two groove portions 32X of the feed roller 32 (FIG. 5) and the second gate roller as viewed from the left and right directions. The outer circumferential circle 62 and the outer circumferential circle of the feed roller 32 are partially overlapped (FIG. 8).

  As a result, the gap between the feed roller 32 and the second gate roller 62 alternates between the feed roller 32 side and the second gate roller 62 side along the left-right direction, as in the case of the first gate roller 52. Is formed. Hereinafter, the peripheral portion of the gap between the feed roller 32 and the second gate roller 62 is referred to as a second gate G2.

  Further, as shown in FIG. 8, the separating portion 25 is compared with an angle θ that is a range in which the high friction portion 32 </ b> R is provided in the feed roller 32 with the center point P <b> 3 representing the central axis of the feed roller 32 as a reference. The angle φ formed by the center point P5 representing the center axis of the first gate roller 52 and the center point P6 representing the center axis of the second gate roller 62 is small. For example, the angle θ is about 120 [°], and the angle φ is about 30 [°].

  Incidentally, the angle φ can also be regarded as an angle formed by the first gate G1 and the second gate G2 with the center point P3 representing the center axis of the feed roller 32 as a reference.

  As described above, the separation unit 25 forms the first gate G <b> 1 by the feed roller 32 and the first gate roller 52, and forms the second gate G <b> 2 by the feed roller 32 and the second gate roller 62.

[1-4. Operation and effect]
In the above configuration, when the banknote cassette 17 according to the first embodiment stores the banknote BL inside, first, as shown in FIG. 9, the stage 23 is moved slightly downward so that it is already on the stage 23. The interval between the uppermost surface of the stacked banknotes BLS and the picker roller 37 is increased.

  Moreover, the banknote cassette 17 rotates the feed shaft 31 and the feed roller 32 in the arrow R1 direction by operating the separation part 25 in the discharge mode.

  And when the banknote BL is conveyed by the conveyance part 13 (FIG. 2), the isolation | separation part 25 will advance a banknote below or ahead along the conveyance path W (FIG. 3), the said banknote BL will be made into the feed roller 32 and It is sandwiched between the second gate rollers 62.

  At this time, since the feed roller 32 is rotating in the direction of the arrow R1, it applies a force that advances downward or forward by friction to the bill BL that comes into contact. The second gate roller 62 rotates in the direction of the arrow R2 without resistance as the bill BL advances. Thereby, the separation unit 25 allows the banknote BL to pass through the second gate G2.

  Subsequently, the separating unit 25 holds the bill BL that has passed through the second gate G <b> 2 between the feed roller 32 and the first gate roller 52.

  At this time, since the feed roller 32 rotates in the direction of the arrow R1, a force that continues to move downward or forward by friction is continuously applied to the bill BL. Further, as in the case of the second gate roller 62, the first gate roller 52 rotates in the direction of the arrow R2 without resistance as the bill BL advances. Thereby, the separation part 25 also allows the first gate G1 to pass through the banknote BL.

  At this time, the bills BL are discharged from the first gate G1 into the accumulation space CS (FIG. 3), collide with the bill stopper 26, and then placed on the stage 23 or the accumulation bills BLS.

  On the other hand, when the banknote cassette 17 is fed out, the banknote cassette 17 first moves the stage 23 upward as shown in FIG. Make contact.

  Moreover, the banknote cassette 17 rotates the feed shaft 31, the feed roller 32, and the picker roller 37 interlock | cooperating with this in the arrow R2 direction by operating the isolation | separation part 25 in isolation | separation mode. Incidentally, since the first gate roller 52 and the second gate roller 62 cannot rotate in the direction of the arrow R1, they remain stationary.

  At this time, in the stage 23, the left and right end portions may be larger than the center portion with respect to the thickness of the stacked banknote BLS, but the center portion on the upper surface of the stage 23 is higher than the left and right end portions. Thus, the stacked banknote BLS can be positively pressed against the picker roller 37.

  The separation unit 25 applies a frictional force between the high friction part 37R of the picker roller 37 and the uppermost banknote BL1 of the stacked banknotes BLS, and applies a backward force to the banknote BL1. As a result, the bill BL1 advances backward and tries to enter the first gate G1.

  At this time, in the stacked banknote BLS, between the banknotes BL adjacent to each other, such as between the uppermost banknote BL1 and the second banknote BL from the top, or between the second and third banknotes BL from the top. In some cases, a relatively strong frictional force may be generated. In this case, as shown in FIG. 11, the second and subsequent banknotes BL are pulled by the uppermost banknote BL1 and attempt to enter the first gate G1 together with the banknote BL1.

  As described above, the first gate G1 has entered the first gate G1 because the tip of the ridge 52Y of the first gate roller 52 slightly enters the groove 32X of the feed roller 32 (FIG. 5). The coming banknote BL is bent so as to wave. Further, the first gate G1 is optimized when the position of the first gate roller 52 with respect to the feed roller 32 is appropriately adjusted, and the gap formed between the two passes the single banknote BL.

  For this reason, the first gate G1 allows the uppermost banknote BL1 to enter, while the first gate roller 52 that is stationary blocks the entrance of the second and subsequent banknotes BL, and separates and transports only the banknote BL1. Try to travel along the road W.

  As shown in FIG. 11, paying attention to the uppermost banknote BL1 and the second banknote BL2, the frictional force acting between the feed roller 32 and the uppermost banknote BL1 is N1, and the uppermost banknote. The frictional force acting between BL1 and the second bill BL2 is N2, and the frictional force acting between the second bill BL2 and the first gate roller 52 is N3. Incidentally, in FIG. 11 and FIGS. 12 and 13 to be described later, the feed roller 32 and the first gate roller 52 and the second gate roller 62 are spaced apart for convenience of explanation.

  In the separating unit 25, since the frictional force N1 is relatively large, the uppermost banknote BL1 is surely entered into the first gate G1, but the banknote BL entering the first gate G1 due to the magnitude relationship between the frictional forces N2 and N3. Will be different.

  That is, when frictional force N3> frictional force N2, the separating unit 25 can dam the second banknote BL2 by the first gate roller 52, so that only the uppermost banknote BL1 can enter. .

  On the other hand, when the frictional force N2> frictional force N3 due to various factors such as static electricity and humidity, the separating unit 25 dams the second banknote BL2 by the first gate roller 52 as shown in FIG. It cannot be stopped and the uppermost banknote BL1 and the second banknote BL2 are allowed to enter.

  Incidentally, since the distance between the feed roller 32 and the first gate roller 52 is adjusted in consideration of the thickness of the banknote BL, the first gate G1 is limited to allowing at most two banknotes BL to enter. There is almost no entry of the above bills BL. That is, the third and subsequent banknotes BL are blocked by the first gate roller 52 due to thickness restrictions.

  The uppermost banknote BL1 and the second banknote BL2 that have passed through the first gate G1 proceed rearward or upward with the rotation of the feed roller 32 and the sub-feed roller 33, and eventually the leading end of the banknote BL1 and the second banknote BL2 pass through the second gate G2. To reach. At this time, the frictional force N3 continues to act between the second banknote BL2 and the stationary first gate roller 52 even when the leading end reaches the vicinity of the second gate G2.

  Similarly to the first gate G1, the second gate G2 has the tip of the ridge 62Y of the second gate roller 62 slightly inserted into the groove 32X of the feed roller 32, so that the bill enters the second gate G2. Curve the BL to wave. Further, the position of the second gate roller 62 with respect to the feed roller 32 is appropriately adjusted so that the second gate G2 allows approximately one bill BL to pass therethrough, and the size of the gap formed between them is optimized. ing.

  For this reason, the second gate G2 allows the uppermost banknote BL2 to enter, while the second gate roller 62 that is stationary stops the entry of the second banknote BL2, and separates only the banknote BL1 to convey the path. Try to travel along W.

  Here, assuming that the frictional force acting between the second bill BL2 and the second gate roller 62 is N4 (FIG. 12), the stationary first gate roller 52 and second gate roller 62 and two sheets are stationary. The frictional force acting between the bills BL2 of the eyes is (N3 + N4). That is, the frictional force (N3 + N4) acting on the banknote BL2 at this time is significantly higher than the frictional force N3 acting on the first gate G1.

  For this reason, in the separation unit 25, even if the frictional force N2> the frictional force N3, the possibility of the frictional force N2 <frictional force (N3 + N4) is extremely high, whereby the first gate roller 52 and the second gate roller 62 Since the second banknote BL2 can be dammed by the cooperation, the top banknote BL1 alone can be entered.

  As a result, the separation unit 25 can separate only the uppermost banknote BL1 from the second and subsequent banknotes BL, and can advance the banknote BL1 along the transport path W. 2).

  Incidentally, the high friction portion 32R of the feed roller 32 is adjusted so that the frictional force N1> the frictional force (N3 + N4). For this reason, in the separation part 25, when only the uppermost banknote BL1 can be separated at the first gate G1, even if only the banknote BL1 enters the second gate G2, the banknote BL1 is transported by the feed roller 32. It can continue to travel along W.

  Further, the separating unit 25 is configured such that the feed roller 32 (32C) and the second gate roller 62 in the second gate G2 are larger than the distance between the feed roller 32 (32A and 32B) in the first gate G1 and the first gate roller 52. The position of each part is adjusted to widen the interval.

  Therefore, the separation unit 25 can set the frictional force N4 to a minimum value that satisfies the frictional force N2 <frictional force (N3 + N4) when the frictional force N2> the frictional force N3. Thereby, when the separating part 25 can separate the uppermost banknote BL1 into only one sheet at the first gate G1, the frictional force acting on the banknote BL1 at the second gate G2 can be minimized. The load applied to the banknote BL1 can be minimized.

  In addition, the separation unit 25 optimizes the gap formed between the feed roller 32C and the second gate roller 62 in the second gate G2 when the bill BL is passed through.

  For this reason, when only the uppermost banknote BL1 has entered the second gate G2, the separating unit 25 applies a relatively small frictional force from the second gate roller 62 to the banknote BL1. On the other hand, when the banknote BL1 and the second banknote BL2 are entered, the separating unit 25 adds the both to the feed roller 32C because the total thickness is larger than the thickness of one banknote BL. The second gate roller 62 is largely curved, and a relatively large frictional force N4 is applied using the rigidity of both bills BL. Thereby, in the separation part 25, the friction force N4 can be made to act positively with respect to the 2nd banknote BL.

  Further, the separating unit 25 positions the second gate roller 62 not on the same axis as the first gate roller 52 but behind and above the first gate roller 52, so that the separation unit 25 follows the conveyance path W in the separation mode. The proceeding banknote BL reaches the second gate G2 after passing through the first gate G1.

  As a result, the separating unit 25 rubs the second gate G2 against only a small number of banknotes BL that have passed through the first gate G1, instead of the same number of banknotes BL as the number of banknotes BL that are about to enter the first gate G1. Since the force N4 only needs to be applied, it is not necessary to increase the frictional force N4 carelessly.

  According to the above configuration, the separation unit 25 of the banknote cassette 17 according to the first embodiment forms the first gate G1 between the feed roller 32 and the first gate roller 52, and the feed roller 32 and the first gate roller 52. A second gate G 2 was formed between the two gate rollers 62. As a result, even if the separating unit 25 allows the first bill G1 to pass through the first bill G1 because the frictional force N2 between the uppermost bill BL1 and the second bill BL2 is large, the second bill. While the friction force N3 is applied to BL2 by the first gate roller 52, the second gate roller 62 can further apply the friction force N4 to the second gate G2. The banknote BL2 is prevented from entering and can be transported in a state separated into only the topmost banknote BL1.

[2. Second Embodiment]
The banknote cassette 117 (FIG. 3) according to the second embodiment is different from the banknote cassette 17 according to the first embodiment in that the banknote cassette 117 has a separation unit 125 instead of the separation unit 25, but other parts. It is configured in the same way.

  As shown in FIGS. 14 to 18 corresponding to FIGS. 4 to 8 respectively, the separation unit 125 is different from the separation unit 25 according to the first embodiment in that the feed roller 32, the sub-feed roller 33, and the second Although the parts relating to the gate roller 62 are different, the other parts are configured in the same manner.

  That is, the separation unit 125 includes feed rollers 132A and 132B that replace the feed rollers 32A, 32B, and 32C, a second gate shaft 161 that replaces the second gate shaft 61, and second gate rollers 162A and 162B that replace the second gate roller 62. The number of sub-feed rollers 33 is three.

  In the second embodiment, two feed rollers 132A and 132B are passed through the feed shaft 31. The feed rollers 132A and 132B are located on the right side and the left side of the feed shaft 31, respectively.

  The feed rollers 132A and 132B are configured similarly. For convenience of explanation, the feed rollers 132A and 132B are collectively referred to as a feed roller 132 below.

  Compared with the feed roller 32 in the first embodiment, the feed roller 132 has a point that is configured in a columnar shape with the central axis directed in the left-right direction, and the diameter thereof is substantially the same, while the feed roller 132 is along the central axis. The length of the direction (that is, the left-right direction) is enlarged.

  In addition, the number of groove portions 132X formed on the outer peripheral portion of the feed roller 132 is increased to three, and accordingly, four ridge portions 132Y are formed. In the feed roller 132, two of the three groove portions 132X are opposed to the two ridge portions 52Y of the first gate roller 52, respectively.

  As a result, there is a gap between the feed roller 132 and the first gate roller 52 that alternates between the feed roller 132 side and the first gate roller 52 side along the left-right direction as in the first embodiment. It is formed. Hereinafter, the peripheral part of this gap among the feed roller 132 and the first gate roller 52 is referred to as a first gate G1 in this embodiment.

  In the second embodiment, as in the first embodiment, the feed shaft 31 has a sub-feed roller 33 penetrating outside the left and right feed rollers 132 and the left and right feed rollers. The sub-feed roller 33 is also passed through the middle of 132, that is, the center of the feed shaft 31.

  On the other hand, the second gate shaft 161 extends in the left-right direction as compared with the second gate shaft 61 in the first embodiment, from the right end of the right feed roller 132A to the left end of the left feed roller 132B. The distance is slightly shorter than the distance.

  The second gate rollers 162A and 162B have such shapes that the two ridges 62Y of the second gate roller 62 in the first embodiment are made independent of each other. That is, the second gate rollers 162A and 162B have the same outer diameter as that of the first gate roller 52, and have a flat columnar shape or a disc shape with a very short length in the direction along the central axis (that is, the left-right direction). Is formed.

  The second gate rollers 162A and 162B are configured in the same manner. For convenience of explanation, the second gate rollers 162A and 162B are collectively referred to as a second gate roller 162 below.

  The second gate roller 162 is opposed to the innermost one of the three groove portions 132X in the feed roller 132 (FIG. 15), and is similar to the first embodiment when viewed from the left and right direction. The outer peripheral circle of the two-gate roller 162 and the outer peripheral circle of the feed roller 132 are partially overlapped (FIG. 18).

  As a result, the gap between the feed roller 132 and the second gate roller 162 is reciprocated between the feed roller 132 side and the second gate roller 162 side along the left-right direction as in the first embodiment. Is formed. Hereinafter, the peripheral portion of the gap between the feed roller 132 and the second gate roller 162 is referred to as a second gate G2 in this embodiment.

  As described above, the separation unit 125 according to the second embodiment forms the first gate G1 by the feed roller 132 and the first gate roller 52, and the second gate G2 by the feed roller 132 and the second gate roller 162. Forming.

  In the above configuration, the banknote cassette 117 according to the second embodiment operates the separation unit 125 in the separation mode as in the first embodiment when the banknotes BL housed therein are fed out.

  The first gate G1 of the separation unit 125 allows the uppermost banknote BL1 in the stacked banknote BLS to enter, while the first gate roller 52 that is stationary blocks the entrance of the second and subsequent banknotes BL, and the banknote BL1. Only these are separated and advanced along the transport path W.

  When the frictional force N3> the frictional force N2, the first gate G1 can dam the second banknote BL2 by the first gate roller 52 as shown in FIG. 11 in the first embodiment. Therefore, only the uppermost banknote BL1 can be entered.

  On the other hand, when frictional force N2> frictional force N3 due to factors such as static electricity and humidity, the first gate G1 is moved to the second gate by the first gate roller 52 as shown in FIG. 12 in the first embodiment. The banknote BL2 cannot be dammed, and the uppermost banknote BL1 and the second banknote BL2 are allowed to enter.

  The second gate G2 allows the uppermost banknote BL2 to enter, while the stationary second gate roller 162 blocks the entry of the second banknote BL2, and separates only the banknote BL1 to convey the transport path W. Trying to progress along.

  At this time, in the second gate G2, as in the first embodiment, even if the frictional force N2> the frictional force N3, the possibility of the frictional force N2 <frictional force (N3 + N4) is extremely high. Since the second banknote BL2 can be dammed by the first gate roller 52 and the second gate roller 162, only the uppermost banknote BL1 can enter.

  As a result, as in the first embodiment, the separation unit 125 can separate only the uppermost banknote BL1 from the other banknotes BL and advance the banknote BL1 along the transport path W. It can be delivered to the transport unit 13 (FIG. 2).

  In other respects, the separation unit 125 according to the second embodiment can achieve the same functions and effects as the separation unit 25 according to the first embodiment.

  According to the above configuration, the separating unit 125 of the banknote cassette 117 according to the second embodiment forms the first gate G1 between the feed roller 132 and the first gate roller 52, and the feed roller 132 and the first gate roller 52. A second gate G 2 was formed between the two gate rollers 162. As a result, even if the separation unit 125 passes both the first and second bills BL1 because the frictional force N2 between the uppermost bill BL1 and the second bill BL2 is large in the first gate G1, the second bill While the frictional force N3 is applied to BL2 by the first gate roller 52, the second gate roller 162 can further apply the frictional force N4 to the second gate G2. The banknote BL2 is prevented from entering and can be transported in a state separated into only the topmost banknote BL1.
