Abstract

PROBLEM TO BE SOLVED: To enable media to be accumulated in neat order on an accumulation surface inclined against the horizontal plane.SOLUTION: In a rejection cassette 16, an accumulation surface 31S of an accumulation base 31 is inclined forward against the horizontal plane, and an accumulation guide 50 is attached to a front end of the accumulation base 31. The rejection cassette 16 advances a bank note discharged from a discharge unit 22 downward ahead on the accumulation surface 31S or accumulated bank notes BLS, causing the bank note to abut on the accumulation guide 50 to make it part of the accumulated bank notes BLS, and holds the accumulated bank notes BLS on the accumulation surface 31S while supporting the same with the accumulation guide 50. Therefore, when lowering the accumulation base 31 together with the accumulated bank notes BLS due to an increase in the weight of the accumulated bank notes BLS, the rejection cassette 16 can smoothly lower the accumulation base 31 while preventing the generation of a friction force, by not causing the accumulated bank notes BLS to slide against the accumulation guide 50 or a front side part 21A of a casing 21.

Description

  The present invention relates to a detection apparatus and a medium transaction apparatus, and is suitable for application to, for example, an automatic teller machine (ATM) that performs a desired transaction by inserting a medium such as banknotes.

  Conventionally, in an automated teller machine installed in a financial institution or a convenience store, for example, the customer is allowed to deposit cash such as banknotes and coins according to the contents of the transaction with the customer, and the cash is withdrawn to the customer. Has been made.

  As an automatic teller machine, for example, a deposit / withdrawal unit for transferring and receiving banknotes with a customer, a transport unit for transporting banknotes, and a discrimination unit for identifying the denomination and authenticity of inserted banknotes There has been proposed one having a temporary holding section for temporarily holding banknotes, a banknote cassette for storing banknotes for each denomination, and a reject cassette for storing banknotes that should not be reused.

  This automatic teller machine, when a customer inserts banknotes into a deposit / withdrawal part in a deposit transaction, conveys the inserted banknotes and discriminates them with a discrimination part, and stores the banknotes identified as normal banknotes in a temporary holding part On the other hand, the banknotes identified as not to be traded are returned to the deposit / withdrawal unit and returned to the customer.

  Subsequently, when the deposit amount is confirmed by the customer, the automatic teller machine pays out the banknotes stored in the temporary holding unit and re-discriminates the denomination by the discrimination unit. While storing in a banknote cassette, the banknote discriminated that the degree of damage is large is stored in a rejection cassette.

  As this reject cassette, for example, by stacking banknotes on a mounting table inclined with respect to a horizontal plane, the occupied area is reduced compared to stacking banknotes horizontally, and the cash dispenser is downsized. There has been proposed one that contributes to (see, for example, Patent Document 1).

  For example, a conventional reject cassette 516 shown in FIG. 13A has a discharge portion 22 that discharges banknotes on the upper side of the casing 21, and a stacking table 31 in an internal space 21 </ b> S formed inside the casing 21. have.

  The stacking table 31 has a stacking surface 31 </ b> S that is an upper surface thereof inclined with respect to a horizontal plane, and stacks banknotes in the vertical direction so that the stacking surface 31 </ b> S faces the sheet of banknotes. Further, the stacking table 31 can be moved in the vertical direction along a movement axis (not shown), and is supported from below by a stacking spring 33.

  A bill abutting portion 540 for abutting the front end portion of bills stacked on the stacking surface 31S (hereinafter referred to as a stacked bill BLS) is attached to the inside of the front side portion 21A of the casing 21. ing.

  The stacking spring 33 is compressed according to the weight of the stacked banknotes BLS stacked on the stacking table 31, and gradually moves the stacking table 31 and the stacked banknotes BLS downward as shown in FIG. Accordingly, the conventional reject cassette 516 has a substantially constant interval (hereinafter referred to as an accumulation interval DC) between the upper guide 29 formed on the uppermost surface of the stacked banknote BLS and the upper portion of the internal space 21S and the stacking table 31. Can be secured, and banknotes can be sequentially accumulated.

JP 2012-46301 A (FIG. 6 etc.)

  However, in the reject cassette 516 having such a configuration, force is applied from the stacked banknote BLS to both the stacking surface 31S and the banknote abutting portion 540 when gravity acts on the stacked banknote BLS.

  For this reason, in the reject cassette 516, a frictional force is generated between the stacked banknote BLS and the banknote abutting portion 540, and the downward movement of the stacking base 31S and the stacked banknote BLS is inhibited.

  As a result, in the reject cassette 516, the stacking interval DC cannot be ensured between the uppermost surface of the stacked banknotes BLS and the upper guide 29. Therefore, there is a problem that the banknotes are clogged and the banknotes cannot be properly collected.

  The present invention has been made in consideration of the above points, and an object of the present invention is to propose a medium stacking apparatus and a medium transaction apparatus capable of orderly stacking a medium on a stacking plane inclined with respect to a horizontal plane.

  In order to solve this problem, in the medium storage device of the present invention, a discharge unit that discharges a medium into a storage space in which a sheet-shaped medium is stored, and a medium that is provided in the storage space and is discharged from the discharge unit. A stacking table for stacking on a stacking surface inclined with respect to the vertical direction, a stacking table moving unit for moving the stacking table along the stacking direction for stacking media, and a stacking unit mounted on the stacking table and stacked on the stacking surface. An accumulation guide for supporting the medium is provided by an accumulation facing surface facing the lower side of the medium or the vicinity thereof.

  In the medium transaction apparatus of the present invention, an acquisition unit that acquires a sheet-like medium to be traded from a user, a conveyance unit that conveys the medium from the acquisition unit, and a storage that should store the medium conveyed by the conveyance unit A discharge unit that discharges the medium into the space; a stacking table that is provided in the storage space and stacks the medium discharged from the discharge unit on a stacking surface inclined with respect to the vertical direction; and a stacking direction in which the medium is stacked And a stacking guide that is attached to the stacking table and supports the medium by a stacking facing surface that faces the lower side of the medium stacked on the stacking surface or the vicinity thereof. I did it.

  In the present invention, the banknotes discharged from the discharge portion are stacked on the stacking surface, and the lower side of the stacked banknotes is supported by contacting the stacking facing surface of the stacking guide, thereby collecting the banknotes on the peripheral side surface surrounding the storage space. The stacking table and the stacked banknotes can be smoothly lowered without sliding.

  According to the present invention, the lower side of the stacked banknotes formed by stacking the banknotes discharged from the discharge unit is brought into contact with and supported by the stacking facing surface of the stacking guide. The stacking table and the stacked banknotes can be smoothly lowered without sliding the stacked banknotes. Thus, the present invention can realize a medium stacking apparatus and a medium transaction apparatus capable of orderly stacking media on a stacking surface inclined with respect to a horizontal plane.

  The receipt issuing port 8 is a part that issues a receipt on which transaction details are printed at the end of transaction processing. Incidentally, a receipt processing unit (not shown) for printing transaction contents and the like on the receipt is provided on the back side of the receipt issuing port 8.

  In the following, the 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, and the upper side and the lower side. Is defined and explained.

  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 banknotes, 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.

  Incidentally, the housing | casing 2 is comprised by the door which can open and close some side surfaces, such as a front side and a rear surface side. That is, the housing | casing 2 protects the banknote accommodated in the banknote depositing / withdrawing machine 10 by closing each door as shown in FIG. 1 at the time of the transaction operation | movement which performs the transaction regarding cash with a customer. . On the other hand, the housing 2 can be easily operated on each part by opening the doors as necessary during maintenance work performed by an operator or the like.

  As shown in the side view of FIG. 2, the banknote depositing / dispensing machine 10 includes a plurality of parts that perform various processes relating to banknotes. 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 banknote transport destination by reading and executing a predetermined program from a ROM or flash memory (not shown). Various processes such as processing are performed.

  Moreover, the banknote control part 11 has a memory | storage part which consists of RAM, flash memory, etc. inside, and memorize | stores various information in this memory | storage part.

  For example, when a customer performs a deposit transaction for depositing banknotes, the banknote control unit 11 receives a predetermined operation input via the operation display unit 6 (FIG. 1), and then opens the shutter to form the deposit / withdrawal unit 12. A bill is inserted into the accommodated storage space 12A.

  When a banknote is inserted into the accommodation space 12 </ b> A, the deposit / withdrawal unit 12 closes the shutter, pays out banknotes one by one from the accommodation space 12 </ b> A, and delivers the banknote to the transport unit 13. The transport unit 13 is configured by a plurality of rollers, belts, and the like, and advances the banknote configured in a rectangular paper sheet shape along the short side direction and transports it to the discrimination unit 14.

  The discrimination unit 14 discriminates the denomination and authenticity of the banknote, the degree of damage, and the like using an optical element, a magnetic detection element, and the like while conveying the banknote inside the banknote control unit 11. To notify. 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 discriminated as normal banknotes in the discrimination unit 14 by, for example, transporting the banknotes to the temporary storage unit 15 while holding the reject banknotes identified as not to be traded. 12 and return to the customer.

  Thereafter, the banknote control unit 11 allows the customer to confirm the deposit amount via the operation display unit 6, transports the banknote held in the temporary storage unit 15 to the discrimination unit 14 by the transport unit 13, and denominations and damages thereof. 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 which should withdraw, after receiving predetermined operation input via the operation display part 6 (FIG. 1), for example, when a customer performs the withdrawal transaction which withdraws a banknote. The banknote is fed out from the banknote cassette 17 and conveyed to the discrimination unit 14 by the conveyance unit 13.

  Subsequently, the banknote control unit 11 discriminates the banknotes by the discrimination unit 14, transports the banknotes to the deposit / withdrawal unit 12 by the transport unit 13, and accumulates them in the accommodation space 12 </ b> A. Open the shutter and let the customer pick it up.

  In this way, the reject cassette 16 is configured so that when reject banknotes that are highly damaged and are not reused are transported by the transport unit 13, they are stored therein.

[1-2. Reject cassette configuration]
Next, the configuration of the reject cassette 16 will be described. As shown in FIGS. 3A and 4, the reject cassette 16 has a plurality of components mounted in a housing 21 that is configured as a rectangular parallelepiped as a whole.

  FIG. 3 is a side view of the reject cassette 16 as viewed from the left side, and FIG. 4 is a perspective view of a part of the reject cassette 16 as viewed from the upper left side. For convenience of explanation, in FIG. 3 and FIG. 4, each component is simplified, and some components are omitted or transmitted.

  The casing 21 (FIG. 3) substantially closes the front, back, top, bottom, and left and right side surfaces, and forms an internal space 21S as a storage space therein. The internal space 21S is formed in a trapezoidal shape with the front side surface and the rear side surface as an upper base and a lower base, respectively, when viewed from the left-right direction.

  On the upper side in the housing 21, a discharge unit 22 that discharges the bills conveyed from the conveyance unit 13 into the internal space 21 </ b> S is provided. In the discharge part 22, a conveyance path 25 is formed along the vertical direction so as to be sandwiched from the front and rear by the conveyance guides 23 and 24 that guide the banknote.

  The conveyance guide 23 is located behind the conveyance path 25 and has a relatively short vertical length. The conveyance guide 23 is provided with a cylindrical drive roller 26.

  The drive roller 26 has a central axis directed in the left-right direction, and a part of the peripheral side surface is exposed to the conveyance path 25 side from a hole formed in the conveyance guide 23. Further, the driving roller 26 rotates in the direction of the arrow R1 when a driving force is transmitted from an actuator (not shown).

  The conveyance guide 24 is located on the front side of the conveyance path 25 and has a relatively long vertical length. The conveyance guide 24 is provided with a cylindrical idle roller 27.

  The idle roller 27 has a central axis directed in the left-right direction like the drive roller 26, and conveys a part of the peripheral side surface from a hole formed in the conveyance guide 24 at a height facing the drive roller 26. It is exposed to the road 25 side. The idle roller 27 is configured to freely rotate. When the drive roller 26 rotates in the direction of the arrow R1, the idle roller 27 rotates in the direction of the arrow R2.

  With this configuration, when the banknote having the short side direction as the traveling direction is transported from the transport section 13 (FIG. 2) located on the upper side, the discharging section 22 is driven by the drive roller 26 and the idle roller 27 facing each other. Pinch.

  Subsequently, the discharge unit 22 rotates the driving roller 26 so as to convey the sandwiched banknote downward along the conveyance path 25 and then discharge it into the internal space 21S.

  On the other hand, an accumulation base 31 is provided below the discharge part 22 in the housing 21. The stacking table 31 is configured such that a plate-like member that is thin in the vertical direction and long in the horizontal direction is tilted clockwise by a predetermined tilt angle θ as viewed from the left. Therefore, the accumulation surface 31S that is the upper surface of the accumulation table 31 is inclined forward by an inclination angle θ with respect to the horizontal plane.

  The stacking table 31 is a stacking surface 31S in which the banknotes released from the discharge unit 22 are inclined forward by an inclination angle θ with respect to the horizontal plane, or banknotes already stacked on the stacking surface 31S (hereinafter referred to as stacking banknotes BLS). On the top).

  By the way, as shown in FIG. 4, the left and right sides in the internal space 21S of the housing 21 are provided with moving shafts 32 each having an elongated cylindrical shape with the central axis directed in the vertical direction.

  On the other hand, as shown in FIG. 4, the stacking table 31 has movement guides 31 </ b> A attached to the left and right. The movement guide 31A is provided with a shaft hole penetrating in the vertical direction. The shaft hole is a round hole having a diameter slightly larger than the diameter of the moving shaft 32, and the moving shaft 32 is inserted therethrough.

  With this configuration, the stacking table 31 can move in the vertical direction along the moving shaft 32 in the internal space 21 </ b> S while sliding the shaft hole of the moving guide 31 </ b> A on the moving shaft 32.

  When the stacking table 31 is positioned at the uppermost position in the internal space 21 </ b> S, the upper rear end portion thereof is brought into contact with the lower surface of the transport guide 23. At this time, the stacking table 31 has a predetermined stacking interval DC between the upper guide 29 extending in front of the conveyance guide 24 and the stacking surface 31S.

  The stacking table 31 is supported on the bottom of the casing 21 via left and right stacking springs 33. The integrated spring 33 is a so-called coil spring, and is attached so as to surround the periphery of the moving shaft 32 as shown in FIG.

  When banknotes are not placed on the stacking table 31 (FIG. 3A), the stacking spring 33 lifts the stacking table 31 to the uppermost side, and the uppermost rear end of the stacking table 31 is the lower surface of the transport guide 24. The accumulation surface 31S is separated from the upper guide 29 by the accumulation interval DC.

  On the other hand, when a banknote is mounted on the stacking table 31, the stacking spring 33 is compressed according to the weight of the mounted banknote (that is, the stacked banknote BLS) as shown in FIG. Here, the spring constant or the like of the stacking spring 33 is appropriately selected so that the distance between the uppermost surface of the stacked banknotes BLS and the upper guide 29 is maintained at the stacking distance DC.

  In addition to this configuration, two accumulation guides 50 are attached to the front side of the accumulation table 31.

  Each stacking guide 50 is configured in a rectangular parallelepiped shape that is long in the vertical direction and thin in the front-rear direction, and is attached to the front end of the stacking table 31 in the vicinity of the lower end side by side so as to have a predetermined interval therebetween. .

  For this reason, the stacking guide 50 stacks the stacked banknotes BLS that are stacked on the stacking surface 31S of the stacking table 31 and that slides forward and downward on the stacking surface 31S due to the action of gravity. Can be supported.

  Further, when the stacking table 31 is moved in the vertical direction, the stacking guide 50 moves in the vertical direction integrally with the stacking table 31 and the stacked banknotes BLS. In other words, the accumulation guide 50 continues to support the accumulated banknote BLS without sliding with the accumulated banknote BLS when the accumulation platform 31 and the accumulated banknote BLS move in the vertical direction.

  As described above, the reject cassette 16 is provided with the stacking guide 50 on the front side of the stacking table 31 in addition to the stacking table 31 having the stacking surface 31S inclined with respect to the discharge unit 22 for discharging banknotes and the horizontal plane.

[1-3. Operation and effect]
In the above configuration, the reject cassette 16 according to the first embodiment has the accumulation surface 31 </ b> S inclined forward relative to the horizontal surface of the accumulation table 31, and the accumulation guide 50 is attached to the front end thereof.

  When the bill BL is transported from the transport unit 13, the reject cassette 16 transports the bill BL downward by the discharge unit 22 and then discharges it into the internal space 21 </ b> S.

  The banknotes BL released here have their tips brought into contact with the stacking surface 31S of the stacking table 31 or the uppermost surface of the stacked banknotes BLS, and are directed to the front lower side, which is the lower side of the inclined surface. Subsequently, the banknote BL advances forward and downward along the uppermost surface of the stacking surface 31S or the stacked banknote BLS by the action of gravity and gravity when discharged by the discharge unit 22, and comes into contact with the stacking guide 50 and stops. . Thereby, the banknote BL is stacked on the stacking surface 31S or the stacked banknote BLS, and becomes a part of the stacked banknote BLS.

  The stacked banknotes BLS on the stacking table 31 have the stacking surface 31S inclined, so that they always slide down to the front and lower with respect to the stacking table 31, but the front end, that is, the lower side is supported by the stacking guide 50. It remains in the state of being accumulated on the accumulation surface 31S.

  Further, the stacking spring 33 is compressed by increasing the weight of the stacked banknotes BLS on the stacking table 31, and tries to lower the stacking table 31 and the stacked banknotes BLS.

  At this time, the stacked banknotes BLS are placed on the stacking table 31 while being supported by the stacking guide 50, so that the stacked banknote BLS is lowered without sliding with respect to the stacking guide 50 while maintaining the position with respect to the stacking guide 50. be able to. Further, since the stacked banknotes BLS are supported by the stacking guide 50, the stacked banknotes BLS do not come into contact with the front side portion 21A of the housing 21 and do not slide down from the stacking surface 31S to the front lower side.

  As a result, the reject cassette 16 can keep the interval between the uppermost surface of the stacked banknotes BLS and the upper guide 29 substantially at the stacking distance DC, and stacks on the stacked banknotes BLS without clogging the banknotes BL to be discharged next. Can be made.

  According to the above configuration, in the reject cassette 16 according to the first embodiment, the accumulation surface 31S of the accumulation table 31 is inclined forward with respect to the horizontal plane, and the accumulation guide 50 is attached to the front end of the accumulation table 31. The reject cassette 16 advances the banknotes released from the discharge unit 22 forward and downward on the stacking surface 31S or the stacked banknotes BLS, abuts against the stacking guide 50 to be a part of the stacked banknotes BLS, While being supported by the accumulation guide 50, it is held on the accumulation surface 31 </ b> S. Therefore, the reject cassette 16 slides the stacked banknote BLS against the stacking guide 50 and the front side portion 21A of the housing 21 when the stacking base 31 is lowered together with the stacked banknote BLS as the weight of the stacked banknote BLS increases. Without being moved, it can be smoothly lowered by preventing the generation of frictional force.

[2. Second Embodiment]
In the second embodiment, a reject cassette 116 shown in FIGS. 5 and 6 corresponding to FIGS. 3 and 4 is used instead of the reject cassette 16 according to the first embodiment.

  The reject cassette 116 is different from the reject cassette 16 according to the first embodiment in having an accumulation guide 150 instead of the accumulation guide 50, but the other parts are configured in the same manner.

  The accumulation guide 150 is configured around the substrate 151. The substrate 151 is formed in a hollow rectangular parallelepiped shape that is elongated in the vertical direction. The rear surface, the left surface, the right surface, the upper surface, and the lower surface are all closed, while the front surface is largely open.

  Rollers 152 are provided in the vicinity of the upper end and the lower end on the front side of the substrate 151, respectively. The roller 152 is formed in a relatively small cylindrical shape, and its central axis is directed in the left-right direction, and is attached so as to be able to rotate smoothly with respect to the substrate 151.

  The roller 152 embeds almost half of the rear side in the substrate 151 to expose almost half of the front side, and has a predetermined interval with respect to the front side portion 21A of the casing 21 positioned in front of the roller 152.

  In the above configuration, the reject cassette 116 according to the second embodiment has the accumulation surface 31S inclined forward with respect to the horizontal plane of the accumulation table 31, and the accumulation guide 150 is attached to the front end thereof. The accumulation guide 150 is provided with rollers 152 near the upper end and the lower end on the front surface of the substrate 151.

  When the bill BL is transported from the transport unit 13, the reject cassette 116 transports the bill BL downward by the discharge unit 22 and discharges it into the internal space 21S as in the first embodiment. It accumulates on the accumulation | storage banknote BLS, and makes it a part of the said accumulation banknote BLS.

  The stacked banknotes BLS on the stacking table 31 are supported by the stacking guide 150 because the stacking surface 31S is inclined, so that the banknote BLS always slides forward and downward with respect to the stacking table 31. In the same manner as described above, the state of being accumulated on the accumulation surface 31S is stopped.

  Further, the stacking spring 33 is compressed by increasing the weight of the stacked banknotes BLS on the stacking table 31, and tries to lower the stacking table 31 and the stacked banknotes BLS.

  At this time, the stacked banknote BLS is placed on the stacking table 31 while being supported by the stacking guide 150 as in the first embodiment. 21 does not come into contact with the front side portion 21A, and does not slide down from the accumulation surface 31S to the front lower side, and can be smoothly lowered.

  Incidentally, as shown in FIG. 6, the reject cassette 116 moves the stacking table 31 in the vertical direction along the moving shaft 32 inserted through the shaft hole of the moving guide 31 </ b> A. A gap is formed between the front end and the front side portion 21 </ b> A of the housing 21.

  For this reason, the reject cassette 116 can ideally be moved in the vertical direction with the accumulation guide 150 being pulled away from the front side portion 21A.

  However, in the reject cassette 116, the stacking base 31, the moving guide 31A, the moving shaft 32, and the stacking guide 150 may be bent due to lack of rigidity or the like, and a gap due to a manufacturing error may be generated between these components. . Further, the accumulated banknote BLS becomes extremely heavy as the number of sheets increases.

  Therefore, in the reject cassette 116, in the front-rear direction, particularly when the center of gravity position of the stacked banknotes BLS is ahead of the insertion position of the moving shaft 32 with respect to the moving guide 31A, as shown in FIG. In addition, the stacked banknotes BLS may be tilted so as to be tilted forward.

  At this time, the accumulation guide 150 abuts the front side portion 21A of the housing 21, but the circumferential side surface of the roller 152 located at the foremost side abuts the front side portion 21A.

  For this reason, the reject cassette 116 can rotate the roller 152 in contact with the front side portion 21A when the stacking table 31 is lowered together with the stacking bills BLS and the stacking guide 150, so that most of the friction force and the resistance force are generated. And can be smoothly lowered.

  As a result, as in the first embodiment, the reject cassette 116 can keep the interval between the uppermost surface of the stacked banknotes BLS and the upper guide 29 substantially at the stacking interval DC, and clogs the banknote BL to be discharged next. It can be made to accumulate on accumulation banknote BLS without.

  According to the above configuration, the reject cassette 116 according to the second embodiment advances the banknotes released from the discharge unit 22 forward and downward on the stacking surface 31S or the stacked banknotes BLS inclined with respect to the horizontal plane, The stacked banknote BLS is brought into contact with the stacking guide 150 attached to the front end of the stacking table 31 and is held on the stacking surface 31S while being supported by the stacking guide 150. Therefore, the reject cassette 116 slides the stacked banknote BLS against the stacking guide 150 and the front side portion 21A of the housing 21 when the stacking table 31 is lowered together with the stacked banknote BLS as the weight of the stacked banknote BLS increases. Even if the accumulation guide 150 abuts against the front side portion 21A without being moved, the roller 152 can be rotated, and the frictional force can be prevented from being generated and smoothly lowered.

[3. Third Embodiment]
In the third embodiment, a reject cassette 216 shown in FIGS. 8 and 9 corresponding to FIGS. 3 and 4 is used in place of the reject cassette 16 according to the first embodiment.

  The reject cassette 216 differs from the reject cassette 16 according to the first embodiment in that it has an accumulation guide 250 instead of the accumulation guide 50, but the other parts are configured in the same manner.

  The accumulation guide 250 is configured around the substrate 251. The substrate 251 is formed in a rectangular parallelepiped shape that is elongated in the vertical direction, and a bill stopper 252 is formed on the rear surface thereof.

  The bill stopper 252 as a slip-off preventing portion is formed on the rear surface so that the projection shape in the left-right direction is a sawtooth shape, that is, a small step repeatedly appears in the vertical direction.

  In the configuration described above, the reject cassette 216 according to the third embodiment has the accumulation surface 31S inclined forward with respect to the horizontal plane of the accumulation table 31, and the accumulation guide 250 is attached to the front end thereof. The accumulation guide 250 is provided with a stepped bill stopper 252 on the rear surface of the substrate 251.

  When the bill BL is transported from the transport unit 13, the reject cassette 216 is transported downward by the ejecting unit 22 and ejected into the internal space 21 </ b> S, as in the first embodiment.

  The banknotes BL released here have their tips brought into contact with the stacking surface 31S of the stacking table 31 or the uppermost surface of the stacked banknotes BLS, and are directed to the front lower side, which is the lower side of the inclined surface. Subsequently, the bill BL advances forward and downward along the top surface of the stacking surface 31S or the stacking bill BLS due to the momentum when being discharged by the discharge unit 22 or the action of gravity, and eventually comes into contact with the bill stopper 252. Quiesce.

  Thereby, the banknote BL is stacked on the stacking surface 31S or the stacked banknote BLS, and becomes a part of the stacked banknote BLS. That is, the stacked banknotes BLS are formed by stacking a plurality of banknotes BL with the vertical direction as the stacking direction on the stacking surface 31S.

  The stacked banknotes BLS on the stacking table 31 are supported by the stacking guide 250 because the stacking surface 31S is inclined. In the same manner as described above, the state of being accumulated on the accumulation surface 31S is stopped.

  Further, the stacking spring 33 is compressed by increasing the weight of the stacked banknotes BLS on the stacking table 31, and tries to lower the stacking table 31 and the stacked banknotes BLS.

  At this time, the stacked banknote BLS is placed on the stacking table 31 while being supported by the stacking guide 250 as in the first embodiment, so that the housing does not slide with respect to the stacking guide 250. 21 does not come into contact with the front side portion 21A, and does not slide down from the accumulation surface 31S to the front lower side, and can be smoothly lowered.

  As a result, as in the first embodiment, the reject cassette 216 can keep the interval between the uppermost surface of the stacked banknotes BLS and the upper guide 29 substantially at the stacking interval DC, and clogs the banknote BL to be discharged next. It can be made to accumulate on accumulation banknote BLS without.

  In particular, when the stacked bills BLS are stacked, the front end portion of the banknotes BL slides downward with respect to the stacking guide 250 due to the momentum applied by the discharge unit 22 or gravity, and the stacked banknotes BLS and the stacking guide 250 May try to dive in between.

  On the other hand, since the bill stopper 252 can hook the front end of the banknote BL on the formed step, the front end portion of the released banknote BL does not enter between the stacked banknote BLS and the stacking guide 250. .

  As a result, the reject cassette 216 maintains a state in which the newly released banknotes BL are stacked on the uppermost surface of the stacked banknotes BLS, that is, the stacked banknotes BLS are stacked in an orderly manner along the vertical direction that is the stacking direction. be able to.

  Incidentally, for example, in the conventional reject cassette 516 shown in FIG. 13, a bill stopper (not shown) similar to the bill stopper 252 may be provided on the rear surface side of the banknote abutting portion 540.

  In the reject cassette 516 provided with the bill stopper, the bills BL discharged from the discharge unit 22 travels forward and downward along the stacking surface 31S of the stacking table 31 or the uppermost surface of the stacked bills BLS, and the rear surface of the front side portion 21A. It abuts against the bill stopper provided on.

  As a result, in the conventional reject cassette 516, as in the reject cassette 216 according to the third embodiment, the front end portion of the banknote BL slides down below the bill stopper and enters into between the stacked banknote BLS and the bill stopper. Can be prevented.

  However, in the conventional reject cassette 516, when the stacking table 31 is lowered as the weight of the stacked banknote BLS increases, the front end of the stacked banknote BLS is slid downward with respect to the bill stopper. Thereby, in the conventional reject cassette 516, the stacked banknotes BLS may be caught by the bill stopper and cannot be lowered sufficiently. At this time, the interval between the uppermost surface of the stacked banknotes BLS and the upper guide 29 is narrower than the stacking interval DC. As a result, the possibility of clogging the bills BL discharged from the discharge unit 22 has been greatly increased.

  On the other hand, in the reject cassette 216 according to the third embodiment, a bill stopper 252 is provided on the rear surface of the accumulation guide 250 that moves together with the accumulation table 31 in the vertical direction. For this reason, because the reject cassette 216 does not slide the stacked banknote BLS and the bill stopper 252 when the stacking table 31 is lowered, the reject cassette 216 can lower the stacking table 31 and the stacked banknote BLS very smoothly. it can.

  In other words, in the reject cassette 216, the bill stopper 252 is provided on the rear surface of the stacking guide 250, thereby preventing the banknote BL from sinking between the stacking banknote BLS and the stacking guide 250, A smooth descent of the stacked banknotes BLS can be achieved at a high level.

  According to the above configuration, the reject cassette 216 according to the third embodiment advances the banknotes released from the discharge unit 22 forward and downward on the stacking surface 31S or the stacked banknotes BLS inclined with respect to the horizontal plane, It is brought into contact with an accumulation guide 250 attached to the front end of the accumulation table 31. At this time, the reject cassette 216 is superimposed on the uppermost surface of the stacked banknote BLS without sliding the front end of the banknote BL by the bill stopper 252 and is held on the stacking surface 31S while being supported by the stacking guide 250. Therefore, the reject cassette 216 slides the stacked banknote BLS against the stacking guide 250 and the front side portion 21A of the housing 21 when the stacking base 31 is lowered together with the stacked banknote BLS as the weight of the stacked banknote BLS increases. Without being moved, it can be smoothly lowered by preventing the generation of frictional force.

[4. Fourth Embodiment]
In the fourth embodiment, instead of the reject cassette 16 according to the first embodiment, a reject cassette 316 shown in FIGS. 10, 11 and 12 corresponding to FIGS. 3 and 4 is used.

  The reject cassette 316 is different from the reject cassette 16 according to the first embodiment in that it has four banknote abutting portions 340, but includes two stacking guides 50 and other points. About the part, it is comprised similarly.

  As shown in FIG. 11, the banknote abutting portion 340 is configured in a rectangular parallelepiped shape that is long in the vertical direction as a whole, short in the left-right direction, and thin in the front-back direction. The banknote abutting portion 340 includes a substrate 341, a low friction material 342, and a bill stopper 343.

  The substrate 341 is formed in a rectangular parallelepiped shape or a plate shape that is long in the vertical direction, short in the left-right direction, and thin in the front-rear direction, and is relatively long in the vertical direction from the vicinity of the lower end of the upper guide 29 to the vicinity of the lower end of the housing 21. Accounted for. The substrate 341 has a relatively high strength and is not easily deformed.

  The low friction material 342 excludes the rear surface of the substrate 341, that is, the surface facing the stacking table 31 and the stacked banknotes BLS, from the upper end (that is, near the lower end of the upper guide 29) to the vicinity of the upper end that is generally within the stacking interval DC. It is pasted on the part. The low friction material 342 has a small coefficient of friction on its rear surface.

  The bill stopper 343 as a slip-preventing part is provided in the vicinity of the upper end of the rear surface of the substrate 341, that is, in the range of the accumulation interval DC from the vicinity of the lower end of the upper guide 29. Similar to the bill stopper 252 in the third embodiment, the rear surface portion of the bill stopper 343 is formed to have a sawtooth projection shape in the left-right direction, that is, a shape in which small steps repeatedly appear in the vertical direction. Has been.

  Further, the mounting position of the banknote abutting portion 340 is adjusted so as to form a predetermined gap between the rear surface of the low friction material 342 and the front end surface of the stacking table 31.

  In the configuration described above, the reject cassette 316 according to the fourth embodiment has the accumulation surface 31S inclined forward with respect to the horizontal plane of the accumulation table 31, and the accumulation guide 50 is attached to the front end thereof. In addition, the reject cassette 316 is provided with a banknote abutting portion 340 on the front side portion 21 </ b> A of the housing 21 so as to leave a gap from the front end portion of the stacking table 31.

  When the bill BL is transported from the transport unit 13, the reject cassette 316 transports the bill BL downward by the discharge unit 22 and then discharges it into the internal space 21S.

  The banknotes BL released here have their tips brought into contact with the stacking surface 31S of the stacking table 31 or the uppermost surface of the stacked banknotes BLS, and are directed to the front lower side, which is the lower side of the inclined surface. Subsequently, the bill BL advances forward and downward along the top surface of the stacking surface 31S or the stacking bill BLS by the action of the momentum and gravity when discharged by the discharge unit 22, and reaches the stacking guide 50 attached to the front end. Abuts and stops. Thereby, the banknote BL is stacked on the stacking surface 31S or the stacked banknote BLS, and becomes a part of the stacked banknote BLS.

  The stacked banknotes BLS on the stacking table 31 are always supported by the stacking guide 50 because the stacking surface 31S is inclined, so that it always slides forward and downward with respect to the stacking surface 31S. It stays in the accumulated state.

  Further, the stacking spring 33 is compressed by increasing the weight of the stacked banknotes BLS on the stacking table 31, and tries to lower the stacking table 31 and the stacked banknotes BLS. At this time, since the stacked banknotes BLS are supported by the stacking guide 50, the banknotes BLS can be smoothly lowered without sliding down from the stacking surface 31 </ b> S to the front lower side and without contacting the front side portion 21 </ b> A of the housing 21. it can.

  By the way, the stacking guide 50 is ideally formed as long as possible in the vertical direction, and even when the maximum number of stacked banknotes BLS that can be stacked on the stacking surface 31S is stacked, all the stacked banknotes BLS are stacked. It is desirable to support the front end portion in contact with the rear surface of the accumulation guide 50.

  However, since the actual stacking guide 50 has to move up and down integrally with the stacking table 31 without jumping out of the casing 21, there may be a case where a sufficient length cannot be secured in the up and down direction.

  For this reason, in the reject cassette 316, as shown in FIG. 10B, by stacking the banknotes BL on the stacking surface 31S of the stacking table 31, a part of the front side of the stacked banknotes BLS is more than the upper end of the stacking guide 50. May be high.

  In this case, among the bills BL constituting the stacked bills BLS, those whose front end is at a position higher than the upper end of the stacking guide 50 cannot be supported by the stacking guide 50 and proceed forward and downward, The abutment portion 340 is supported in contact with it.

  For this reason, the reject cassette 316 slides some banknotes BL of the stacked banknotes BLS to the banknote abutting portion 340 when the stacking spring 33 is compressed and descends together with the stacking base 31 as the weight of the stacked banknotes BLS increases. I will let you.

  At this time, the reject cassette 316 is smoothly lowered by the action of the low friction material 342 affixed to the rear surface of the banknote abutting portion 340 with almost no frictional force generated with the part of the banknotes BL. Can do.

  Further, the reject cassette 316 contacts the bill stopper 343 of the banknote abutting section 340 when the top surface of the banknote BL discharged from the discharging section 22 is higher than the upper end of the stacking guide 50 at the front end of the stacked banknote BLS. Can be touched.

  As a result, the reject cassette 316 places the banknote BL on the uppermost surface of the stacked banknote BLS without causing the leading edge of the banknote BL to enter between the front surface of the stacked banknote BLS and the rear surface of the low friction material 342 or the stacking guide 50. It can be maintained in the state where it is placed.

  In addition, the bill abutting portion 340 is provided with the bill stopper 343 only in the range of the stacking interval DC from the vicinity of the lower end of the upper guide 29 on the rear surface, and the low friction material 342 is attached to the other portions.

  For this reason, the banknote abutting part 340 suppresses the momentum which is going to advance to the front lower direction in the banknote BL discharge | released from the discharge | release part 22, and is a part of the stack | stuck banknote BLS descend | falling with the stacking base 31 with the bill stopper 343. It is possible to achieve a high level of compatibility between reducing the friction generated between the two by the low friction material 342.

  According to the above configuration, the reject cassette 316 according to the fourth embodiment has the accumulation surface 31S of the accumulation table 31 inclined forward with respect to the horizontal plane, and the accumulation guide 50 is attached to the front end thereof. Further, the reject cassette 316 is provided with a banknote abutting portion 340 in the front side portion 21A of the housing 21 so as to leave a gap with the front end portion of the stacking base 31, and a low friction material 342 is attached to a portion other than the vicinity of the upper end on the rear surface. I attached. Thus, the reject cassette 316 supports the stacked banknote BLS by the stacking guide 50 and holds it on the stacking surface 31S. When the stacking table 31 is lowered together with the stacked banknote BLS, the reject cassette 316 has a frictional force with respect to the front side portion 21A of the housing 21. When the number of stacked banknotes BLS increases and the uppermost surface exceeds the upper end of the stacking guide 50, the front end of the stacked banknotes BLS is brought into contact with the low friction material 342 of the banknote abutting portion 340 to smoothly Can be lowered.

The case where it was made to descend was described.

  However, the present invention is not limited to this. For example, the integrated spring 33 is omitted, and an integrated stand driving unit is configured by a combination of an actuator (not shown), various gears, a belt, and the like. You may make it move to. The same applies to the second to fourth embodiments.

  Furthermore, in the first embodiment described above, the case has been described in which the stacking direction of stacking on the stacking surface 31S of the stacking table 31 and the moving direction of the stacking table 31 are both the vertical direction, that is, the vertical direction.
