Abstract

PROBLEM TO BE SOLVED: To appropriately accumulate sheet-like media.SOLUTION: A release section 22 of a reject storage 16 causes a clamp conveyance section 33 to clamp paper money BL on a clamping face 33A at a clamping position U1, and causes an impeller 38 at the clamping position U1 and a press-bending section 41 at a press-bending position U2 to lift end portions of the paper money BL upward from the clamping surface 33A respectively. Thereby, the release section 22 can lift the left and right end portions upward from the clamping surface 33A just before releasing the paper money BL into the accumulation space 21A, so as to, even after the release, retain the paper money in a state of forming a curved surface SC for a long period of time and further make it glide through the air in the accumulation space 21A with vertical bending strength improved. Consequently, the release section 22 can eventually pile the released paper money BL right above existing paper money BL accumulated on a stage 25 in an orderly fashion.

Description

  The present invention relates to a medium stacking 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 medium such as banknotes.

  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 automated teller machine, for example, a banknote deposit / withdrawal port for receiving and receiving banknotes with customers, a discrimination unit for discriminating the denomination and authenticity of inserted banknotes, and temporarily holding inserted banknotes The thing which has the temporary storage part to perform, the banknote cassette which stores a banknote for every money type, and the rejection store | warehouse | chamber which should store the banknote (reject banknote) which should not be reused is proposed.

  This automatic teller machine, in a deposit transaction, when a customer inserts a banknote into a banknote deposit / withdrawal port, the inserted banknote is discriminated by a discrimination unit, and a banknote discriminated from a normal banknote is held in a temporary holding unit, The banknotes identified as not to be traded are returned to the banknote deposit / withdrawal port and returned to the customer. Subsequently, when the deposit amount is confirmed by the customer, the automatic teller machine re-discriminates the denomination of the banknote held in the temporary holding section by the discrimination section and stores it in each banknote cassette according to the identified denomination. .

  The automatic teller machine is configured to convey a banknote (reject banknote) that should not be reused as it is determined that the degree of damage is large in the discrimination section, and store it separately from other banknotes.

  As this rejection store | warehouse | chamber, for example, what is made to accumulate | stack sequentially by discharge | released the banknote BL conveyed to an internal space, and dropping it.

  For example, as shown in FIG. 23, in the conventional reject box 1516, the banknotes BL conveyed along the short direction are discharged into the internal stacking space 21A by the discharge unit 1522. The discharge unit 1522 holds the banknote BL between the rotating stacking roller 34 and the pressure roller 36, transports the banknote rearward along the transport path W, discharges it into the stacking space 21A, and then rotates the banknote by the rotating impeller 38. Tap BL down. As a result, the reject box 1516 stacks orderly on the stage 25 with the paper surfaces of the bills BL in contact with each other in the stacking space 21A.

  In this reject box 1516, if the leading edge of the banknote BL faces upward or downward after being released, it is not possible to maintain the traveling direction as it is, and it will not fall directly above the existing banknote, so there is a possibility that it cannot be correctly stacked. is there.

  Therefore, as shown in FIGS. 24A and 24B, the reject box 1516 is a position where a part of the banknote BL is sandwiched between the stacking roller 34 and the pressure roller 36 by the impeller 38, as shown in an enlarged view of the discharge unit 1522. The banknote BL is curved in the longitudinal direction (width direction) by lifting it higher than the height.

  As a result, the reject box 1516 can increase the bending strength in the short direction (conveying direction) of the banknotes and enhance the straightness after discharge (see, for example, Patent Document 1).

JP 2007-131428 A (FIG. 5)

  By the way, since the bills BL are handled in various ways in the distribution process, as a result of being bent, the bending strength may be lower than the state of the new bill before distribution, and the stiffness may be reduced. Also, banknotes may become stiff even when the humidity is high.

  In particular, since the banknote BL conveyed to the reject box is determined to have a large degree of damage by the discrimination unit, there is a high possibility that the banknote BL is weak in this way.

  When a banknote BL having such a weak stiffness has been transported, even if it is released after being bent in the longitudinal direction when it is rejected, the reject box reduces straightness due to a part of the banknote BL hanging or the like. In such a case, there is a problem that the banknote cannot be collected correctly in the end.

  And the banknote control part 11 will convey this to the rejection store | warehouse | chamber 16 by the conveyance part 13 as banknote BL which should not be reused if the extent of damage of the banknote BL is large, and if this is small, this will be stored. A bill BL to be reused is transported by the transport unit 13 and stored in a bill cassette 17 corresponding to the denomination.

[1-2. Reject warehouse configuration]
As shown in the side view schematically shown in FIG. 3, the reject box 16 is configured to take bills BL and collect them in a rectangular parallelepiped casing 21.

  The housing | casing 21 forms the accumulation | storage space 21A which accumulate | stores banknote BL inside by substantially obstruct | occluding each front and back, right and left side surfaces.

  A front side surface plate 24 is provided on the front side of the stacking space 21A to determine the position of the front side of the banknotes BL to be stacked, and the banknotes BL are placed on the upper surface of the stacking space 21A. A stage 25 is provided.

  In the front upper part of the housing 21, elongated holes are formed on the left and right, and a discharge portion 22 is provided. The discharge unit 22 takes in the bills BL that are transported along the short direction from the front, transports the bills BL backward, and discharges the bills BL toward the rear as it is into the accumulation space 21A (details). Will be described later).

  A bill stopper 23 is provided above the rear surface inside the housing 21. The bill stopper 23 is attached to the rear side plate of the housing 21 via an elastic body (not shown), and when an external force is applied from the front, the elastic body is made to act elastically.

  Actually, the bill stopper 23 is discharged backward from the discharge portion 22 and, when the leading edge of the bill BL gliding in the stacking space 21A collides with the paper surface facing up and down, the bill stopper 23 absorbs the impact and rebounds. Proceed forward.

  Thereafter, the bills BL are struck downward by an impeller 38 (details will be described later) of the discharge unit 22 and drawn forward, and the front end thereof is pressed against the front side plate 24 so as to be already accumulated on the stage 25. On the banknotes BL, they are neatly stacked so that their paper faces face each other.

  In this way, the reject box 16 collects the bills BL on the stage 25 by taking in the bills BL supplied from the front by the transport unit 13 and discharging the bills BL into the stacking space 21A by the discharge unit 22. Yes.

[1-3. Configuration of discharge part]
As shown in FIG. 4A, which is a right side view in which a part of FIG. 3 is enlarged, and FIG. 4B, which is a rear view thereof, the discharge unit 22 conveys the bills BL from the front to the rear. The conveyance path W is mainly configured.

  The conveyance path W is partitioned in the vertical direction by an upper conveyance guide 31 and a lower conveyance guide 32 arranged above and below the conveyance path W. In other words, the upper and lower gaps in the upper conveyance guide 31 and the lower conveyance guide 32 form the conveyance path W.

  The upper transport guide 31 and the lower transport guide 32 are respectively passed between the front side surface of the casing 21 (FIG. 3) and the front end portion of the stacking space 21 </ b> A, and the bills BL are stacked from the outside of the casing 21 to the stacking space 21 </ b> A. Until it reaches the inside, the bill BL is guided and advanced along the transport path W.

  The upper conveyance guide 31 and the lower conveyance guide 32 are each composed of a thin plate member in the vertical direction, and are provided with holes that penetrate the vertical direction as appropriate.

  In the upper conveyance guide 31, the lower conveyance guide 32, and the conveyance path W, a nipping conveyance unit 33 that nipping the banknote BL from above and below and conveying the banknote BL from the top and bottom is provided.

  The holding and conveying unit 33 is configured to hold the bills BL from above and below by the accumulation roller 34 and the pressure roller 36 disposed respectively on the lower side and the upper side of the conveying path W.

  The stacking roller 34 is formed in a thin cylindrical shape with the central axis directed in the left-right direction, and is penetrated by a shaft 35 that is elongated in the left-right direction so that the central axes coincide with each other.

  As shown in FIG. 4 (B), the shaft 35 is penetrated by two stacking rollers 34 at an appropriate interval in the left-right direction, and is rotatably supported with respect to the casing 21 by a bearing (not shown). Yes.

  The pressure roller 36 is formed in a thin columnar shape in which the radius of the accumulation roller 34 is reduced, and is penetrated by a shaft 37 that is elongated in the left-right direction. The shaft 37 rotatably supports the pressure roller 36 and is urged downward by a spring (not shown) so as to press the pressure roller 36 against the stacking roller 34.

  For this reason, when the banknote BL is located directly below, the pressure roller 36 presses the banknote BL against the stacking roller 34 as shown in FIG. The banknote BL can be held between the stacking rollers 34. Hereinafter, the position in the front-rear direction in which the bill BL is clamped by the stacking roller 34 and the pressure roller 36 is referred to as a clamping position U1.

  In addition, a total of four impellers 38 are passed through the shaft 35 on the left and right sides of each of the two stacking rollers 34 (FIG. 4B). As shown in FIG. 4A, the impeller 38 has four elongated thin plate-like tongue pieces 38B extending radially from a thin cylindrical central portion 38A with the central axis directed in the left-right direction. .

  The tongue piece 38B has flexibility, and when pressed against the bill BL, the B1-B2 cross section in FIG. 4B is bent to the bill BL to some extent while being bent as shown in FIG. 5B. The banknote BL is lifted upward by applying an external force. Incidentally, the position where the tongue piece 38B comes into contact with the bill BL is slightly in front of the clamping position U1, that is, in the vicinity of the clamping position U1.

  Further, the shaft 35 is adapted to transmit a rotational driving force via a motor, a gear or the like (not shown). For this reason, the two pressure rollers 36 and the four impellers 38 rotate integrally with the shaft 35 when the shaft 35 is rotated in the discharge direction R1 (clockwise in FIG. 4A).

  At this time, if the holding and conveying unit 33 holds the banknote BL between the stacking roller 34 and the pressure roller 36, the holding and conveying section 33 advances the banknote BL backward, and between the upper and lower conveyance guides 31 and 32. It can be transported along the formed transport path W.

  Further, the nipping and conveying unit 33 advances the banknote BL backward at a certain speed, so that the banknote BL is moved from the rear end of the upper transport guide 31 and the lower transport guide 32, that is, from the rear end of the transport path W into the accumulation space 21A. Can be released.

  In addition to such a configuration, the discharge portion 22 is provided with a bending portion 41 at the rear end portion of the upper surface of the lower conveyance guide 32. The bending portion 41 is formed in a thin plate shape that is thin in the left-right direction and long in the front-rear direction, and has a trapezoidal shape with a lower bottom longer than an upper base when viewed from the left-right direction. In other words, the bending portion 41 is a rib erected upward from the upper surface of the lower conveyance guide 32.

  The upper surface of the bending portion 41 includes a slope portion 41A that gently rises from the front end to the vicinity of the rear end, and a parallel portion 41B that is substantially parallel to the upper surface of the lower conveyance guide 32 in the vicinity of the rear end.

  The parallel portion 41B has a height relative to the upper surface of the lower conveyance guide 32 that is higher than the clamping surface 33A of the stacking roller 34 and the pressure roller 36 in the clamping conveyance unit 33 and is lower than the lower surface of the upper conveyance guide 31. It is low. Further, the gap formed between the parallel portion 41B and the lower surface of the upper transport guide 31 is larger than the thickness of the banknote BL.

  For this reason, when the bill BL is conveyed from the front to the rear by the nipping and conveying unit 33, as shown in FIG. The banknote BL is gradually pushed upward while sliding along the slope 41A, and the banknote BL is lifted to a position higher than the sandwiching surface 33A of the sandwiching and transporting section 33 by the parallel section 41B.

  Here, the parallel portion 41B of the bending portion 41 is located on the rear side with a certain distance from the clamping position U1. Hereinafter, a position where the parallel portion 41B is approximately in the front-rear direction is referred to as a bending position U2.

  Further, as shown in FIG. 4B, the lower conveyance guide 32 is provided with the bending portions 41 at a total of three locations near the left and right outer ends and near the center of the left and right.

  With this configuration, the discharge unit 22 is moved in the left-right direction with respect to the bill BL by the nipping and conveying unit 33, the impeller 38, and the bending portion 41 in the vicinity of the rear ends of the upper conveying guide 31, the lower conveying guide 32, and the conveying path W. A force directed upward or downward is applied at different locations.

  Specifically, as shown schematically in FIGS. 6A, 6 </ b> B, and 6 </ b> C, the bill BL is pinched by the stacking roller 34 and the pressure roller 36 of the pinch conveyance unit 33 at the right side portion thereof. A force F1 is applied from above and below at each point (hereinafter referred to as a pinching point P1).

  Further, the banknote BL is directed outward from the lower surface side to a position (hereinafter referred to as a contact point P2) where the tongue piece 38B of the impeller 38 abuts on the outside (that is, the right side) from the pinching point P1. Force F2 acts.

  Further, the bill BL is located outside the contact point P2 (that is, on the right side) and in the traveling direction side (that is, the rear) of the bill BL, and the portion where the parallel portion 41B of the bending portion 41 contacts (hereinafter, this is referred to as the bending point P3). The force F3 acts upward from the lower surface side.

  As a result, as shown in FIG. 6A, the bill BL is parallel to a portion substantially parallel to the lower surface of the upper transport guide 31 and the upper surface of the lower transport guide 32 (hereinafter referred to as a parallel surface portion SP). The shape is such that portions inclined in the left-right direction with respect to the surface portion SP (hereinafter referred to as inclined surface portions SL) are alternately connected in the left-right direction.

  Here, the position in the front-rear direction of the bending point P3 is the clamping position U1 where the clamping point P1 and the contact point P2 are located, and the bending position U2 spaced apart from the vicinity thereof by a certain distance.

  For this reason, when the discharge part 22 conveys the banknote BL in the backward direction, the right end portion of the banknote BL lifted at the contact point P2 can be continuously lifted at the bending point P3, and the banknote BL is further curved. It can be made to proceed in the backward direction as it is.

  Thereby, as shown in FIGS. 6B and 6C, the banknote BL forms an inclined surface portion SL that is long in the front-rear direction, and in the vicinity of the boundary between the inclined surface portion SL and the parallel surface portion SP. A curved surface SC such as a side surface of a cylinder or an elliptic cylinder having a central axis along the front-rear direction can be formed.

  At this time, the banknote BL can act on the curved surface SC like a “beam” passed in the front-rear direction, so that the bill BL has a long section in the front-rear direction including both the contact point P2 and the bending point P3. The bending strength regarding the up-down direction of the banknote BL can be increased.

  Incidentally, since the discharge | release part 22 is comprised substantially symmetrically, it can form the inclined surface part SL and the curved surface SC similarly in the right side part of the banknote BL, and can raise bending strength.

  As a result, the discharge unit 22 can prevent the banknote BL from being bent or drooped in the vertical direction after being discharged, and can be moved almost directly behind in the stacking space 21A. Can be stacked in an orderly manner so as to be stacked just above the bills BL.

  As described above, the discharge unit 22 is provided with the bending portion 41 at the rear end portion on the upper surface of the lower conveyance guide 32, so that a long curved surface SC is formed on the banknote BL in the front-rear direction when the banknote BL is conveyed in the rearward direction. The formed space is discharged into the accumulation space 21A.

[1-4. Operation and effect]
In the above configuration, the discharge unit 22 of the reject box 16 applies a force F1 from the vertical direction at the pinching point P1 to the banknote BL at the pinching point P1 by the stacking roller 34 and the pressure roller 36 of the pinch conveyance unit 33, and the impeller 38 applies the force F1. A force F2 is applied from the lower surface side at the contact point P2, and a force F3 is applied from the lower surface side at the bending point P3 by the bending portion 41 (FIG. 6).

  Thereby, the discharge | release part 22 makes the edge part outside the clamping point P1 clamped by the clamping conveyance part 33 among banknotes BL from the clamping surface 33A (FIG. 5 (A)) in the contact point P2 and the bending point P3. Lift up.

  At this time, the discharge unit 22 is disposed at a position closer to the rear ends of the upper conveyance guide 31 and the lower conveyance guide 32 than the pinching point P1 until immediately before the banknote BL is discharged into the accumulation space 21A. The left and right end portions can be lifted upward.

  And the discharge | release part 22 forms the long inclined surface part SL forward and backward by conveying the banknote BL back sequentially by the clamping conveyance part 33, and the boundary vicinity of the said inclined surface part SL and parallel surface part SP, The banknotes BL are discharged into the accumulation space 21A while forming the long curved surfaces SC in the front and rear directions.

  Since the bill BL discharged from the discharge portion 22 can be slid in the accumulation space 21A while maintaining the state in which the bending strength in the vertical direction is increased by the curved surface SC, the bill BL 23 can travel straight back and the bill stopper 23 Can be stacked in an orderly manner immediately above the existing banknotes BL accumulated on the stage 25.

  Moreover, the discharge | release part 22 can form easily the inclined surface part SL which inclines in the left-right direction with respect to the banknote BL by raising the banknote BL upwards also in the contact point P2, The cross-sectional shape is front-back. Therefore, when the banknote BL is transported backward, there is no excessive deformation as it progresses.

  Thereby, since the discharge | release part 22 can form the inclined surface part SL and the curved surface SC reasonably compared with the case where it lifts only by the bending point P3, the banknote BL is not damaged carelessly by curvature. .

  Here, in the conventional discharge | release part 1522 (FIG. 24), as shown to FIG. 7 (A) and FIG. 8 (A), since the banknote BL was supported only in the clamping position U1 regarding the front-back direction, When is weak, there is a possibility that the front end portion (that is, the rear end portion) away from the clamping position U1 hangs downward.

  Also, as shown in FIG. 25, in the conventional discharge portion 1622, when the auxiliary roller 1634 having a slightly larger radius than the accumulation roller 34 is provided on the left and right sides of the accumulation roller 34, or as shown in FIG. Similarly, when the stacking roller 1734 is formed in a bobbin shape in the conventional discharge unit 1722, the banknote BL is supported only at the clamping position U1 in the front-rear direction. For this reason, also in the discharge parts 1622 and 1722, the front-end | tip part (namely, rear-end part) away from the clamping position U1 may hang down similarly.

  On the other hand, in the discharge part 22 according to the present invention, as shown in FIGS. 7 (B) and 8 (B), the bill BL is supported not only at the clamping position U1 but also at the bending position U2. Even if the stiffness of the bill BL is weak, it is possible to greatly reduce the possibility that the leading end portion (rear end portion) away from the holding position U1 hangs downward.

  According to the above configuration, the discharge unit 22 according to the first embodiment holds the banknote BL on the holding surface 33A by the holding conveyance unit 33 at the holding position U1, and the impeller 38 and the bending position at the holding position U1. The end portion of the bill BL is lifted upward from the sandwiching surface 33A by the U2 bending portion 241. As a result, the discharge unit 22 can lift the left and right end portions upward from the clamping surface 33A immediately before discharging the banknote BL into the stacking space 21A. The formed state can be maintained, and the inside of the integrated space 21A can be slid while the bending strength in the vertical direction is increased. As a result, the discharge unit 22 can stack the discharged banknotes BL neatly on the existing banknotes BL stacked on the stage 25.

[2. Second Embodiment]
In the second embodiment, as shown in FIG. 9 corresponding to FIG. 4, the bill BL is discharged into the accumulation space 21A by the discharge portion 122 instead of the discharge portion 22 according to the first embodiment. ing.

[2-1. Configuration of discharge part]
The discharge unit 122 is different from the discharge unit 22 in that it includes a lower conveyance guide 132 and a bending portion 141 instead of the lower conveyance guide 32 and the bending portion 41, but the other portions are configured in the same manner. ing.

  The lower conveyance guide 132 is formed in a thin plate shape like the lower conveyance guide 32, and in addition to the portion corresponding to the accumulation roller 34 and the impeller 38, the lower conveyance guide 132 is also vertically moved to the portion corresponding to the bending portion 141. A hole penetrating therethrough is appropriately drilled.

  The bending portion 141 is configured around a plate-shaped bending piece 142 that is thin on the left and right. The bending piece 142 is formed in a triangular shape having a vertex 142A on the rear upper side when viewed from the left-right direction, and a rotating shaft 143 is provided at the front end.

  As shown in FIG. 10A, the rotating shaft 143 has a section D1-D2 in FIG. 9B, and a bent piece 142 with respect to the lower conveyance guide 132 with the central axis along the left-right direction as the center of rotation. Can be freely rotated counterclockwise R1 or clockwise R2.

  Further, the bending piece 142 is urged upward (that is, counterclockwise direction R2) by a spring (not shown), and the rotation range thereof is restricted by the stopper 144.

  Therefore, when no external force is applied, the bending portion 141 causes the lower conveying guide to be brought into contact with the stopper 144 by bringing a part of the upper surface of the bending piece 142 into contact with the stopper 144 as shown in FIG. In this state, a gap h1 larger than the thickness of the bill BL is formed between the apex 142A and the lower surface of the upper transport guide 31.

  That is, for the normal banknote BL, the discharge unit 122 projects the banknote BL by the bending section 141 in the same manner as in the first embodiment by causing the pressing piece 142 to protrude most upward from the lower conveyance guide 132. Can be lifted upward.

  At this time, as in the first embodiment, the discharge portion 122 applies a force F1 from the up and down direction at the clamping point P1, applies a force F2 from the lower surface side at the contact point P2, and from the lower surface side at the bending point P3. A force F3 is applied (FIG. 6).

  For this reason, the discharge | release part 122 can discharge | release into the accumulation | aggregation space 21A in the state which formed in front and back the inclined surface part SL in the banknote BL.

  On the other hand, in the discharge part 122, when the apparent thickness of the banknote BL is larger than the gap h1 due to the banknotes or folds, as shown in FIG. While being in contact with the lower surface of 31, another part of the bill BL is in contact with the bending piece 142.

  At this time, the bending piece 142 of the bending portion 141 is slightly rotated clockwise by receiving a downward force from the bill BL, and widens the space between the apex 142A and the lower surface of the upper conveyance guide 31. However, an upward force is applied to the bill BL by the biasing force of the spring.

  That is, for the bill BL having a thick apparent thickness, the discharge unit 122 rotates the bending piece 142 in the clockwise direction R1 to reduce the amount of protrusion from the lower transport guide 132, thereby sliding the bill BL. The bill BL can be lifted upward by the curved portion 141 while reducing the dynamic resistance.

  For this reason, the discharge | release part 122 can discharge | release into the accumulation | aggregation space 21A in the state which formed the long curve SC back and forth in the banknote BL similarly to 1st Embodiment.

[2-2. Operation and effect]
In the above configuration, the discharge unit 122 according to the second embodiment causes the force F1 to act on the pinching point P1 from the up and down direction by the accumulation roller 34 and the pressure roller 36 of the pinch conveyance unit 33, and the contact point P2 by the impeller 38. In FIG. 6, a force F2 is applied from the lower surface side, and a force F3 is applied from the lower surface side at the bending point P3 by the bending portion 141 (FIG. 6).

  As a result, the discharge unit 122 holds the end portion of the banknote BL outside the pinching point P1 pinched by the pinch conveyance unit 33 at both the contact point P2 and the bending point P3 (see FIG. 5A). It can be discharged into the accumulation space 21A while being lifted upward.

  At this time, the discharge portion 122 forms a long inclined surface portion SL in the front and back of the banknote BL, and also forms a long curved surface SC in the front and rear in the vicinity of the boundary between the inclined surface portion SL and the parallel surface portion SP. (FIG. 6).

  For this reason, the bills BL discharged from the discharge unit 122 can travel straight backward as in the first embodiment, and after being bounced back to the bill stopper 23, are finally accumulated on the stage 25. It can be stacked neatly above the existing bills BL.

  In addition, the bending portion 141 rotates the bending piece 142 about the rotation shaft 143 as a rotation center and is biased in the counterclockwise direction R1 by a spring. The protrusion amount of the bending piece 142 from the upper surface of the conveyance guide 132 can be changed.

  That is, for the normal bill BL, the discharge unit 122 can sufficiently lift the protruding amount of the bent piece 142 to the maximum, and for the bill BL with a thick apparent thickness, the released piece 142 is clockwise. By rotating to R1 and reducing the amount of protrusion, it can be lifted upward without increasing the sliding resistance and discharged at a sufficient discharge speed.

  Furthermore, since the discharge | release part 122 has controlled the rotation range of the bending piece 142 with the stopper 144, when making the protrusion amount the maximum, the clearance gap h1 can be formed between the lower surfaces of the upper conveyance guide 31, The sliding resistance with respect to the normal banknote BL is not inadvertently increased.

  With respect to other points as well, the discharge unit 122 according to the second embodiment can achieve the same operational effects as the discharge unit 22 according to the first embodiment.

  According to the above configuration, the discharge unit 122 according to the second embodiment holds the bill BL on the holding surface 33A by the holding conveyance unit 33 at the holding position U1, and the impeller 38 and the bending position at the holding position U1. The end portion of the bill BL is lifted upward from the sandwiching surface 33A by the U2 bending portion 141, respectively. Further, the bending portion 141 changes the amount of protrusion from the upper surface of the lower conveyance guide 132 of the bending piece 142 according to the apparent thickness of the bill BL. As a result, the discharging unit 122 can lift the left and right end portions upward from the sandwiching surface 33A without inadvertently increasing the sliding resistance immediately before discharging the banknote BL into the stacking space 21A. The curved surface SC can be discharged at a high speed, and the inside of the integrated space 21A can be slid while the bending strength in the vertical direction is increased by the curved surface SC. As a result, the discharging unit 122 can stack the discharged banknotes BL neatly on the existing banknotes BL stacked on the stage 25.

[3. Third Embodiment]
In the third embodiment, as shown in FIG. 11 corresponding to FIG. 4, the bill BL is discharged into the accumulation space 21 </ b> A by the discharge portion 222 instead of the discharge portion 22 according to the first embodiment. ing.

[3-1. Configuration of discharge part]
The discharge unit 222 is different from the discharge unit 22 in that it includes a lower conveyance guide 232 and a bending portion 241 instead of the lower conveyance guide 32 and the bending portion 41, but the other portions are configured similarly. ing.

  The lower conveyance guide 232 is formed in a thin plate shape in the same manner as the lower conveyance guide 32, and in addition to the portion corresponding to the accumulation roller 34 and the impeller 38, the lower conveyance guide 232 is also vertically A hole penetrating therethrough is appropriately drilled.

  The bending portion 241 is configured by a combination of a cylindrical roller 242 and a holder 243 that rotatably supports the roller 242.

  The roller 242 is configured in a small cylindrical shape such that the pressure roller 36 is reduced in diameter and thinned in the left-right direction.

  The holder 243 has a trapezoidal side plate extending from the left and right sides of the thin plate-like bottom plate portion that is thin in the top and bottom direction, and extends upward. The roller 242 is rotatable between the left and right side plates. It is pivotally supported.

  The holder 243 is attached to the lower conveyance guide 232, and exposes the upper portion of the holder 243 and the roller 242 from the upper surface of the lower conveyance guide 232, and between the upper end of the roller 242 and the lower surface of the upper conveyance guide 31. A gap larger than the thickness of the banknote BL is formed.

  With this configuration, the discharge unit 222 brings the end portion of the bill BL into contact with the bending portion 241 when the bill BL is conveyed backward. At this time, the bending portion 241 can lift the bill BL upward while rotating the roller 242 by friction with the bill BL progressing backward.

  Similarly to the first embodiment, the discharge portion 222 applies a force F1 from the up and down direction at the pinching point P1, applies a force F2 from the lower surface side at the contact point P2, and applies a force from the lower surface side at the bending point P3. F3 is applied (FIG. 6).

  For this reason, the discharge | release part 222 can discharge | release into the accumulation | aggregation space 21A in the state which formed the long curved surface SC before and behind the banknote BL similarly to 1st Embodiment.

[3-2. Operation and effect]
In the above configuration, the discharge unit 222 according to the third embodiment holds the bill BL on the holding surface 33A (FIG. 5A) by the stacking roller 34 and the pressure roller 36 of the holding and conveying unit 33 at the holding position U1. At the same time, the end portion of the banknote BL is lifted above the clamping surface 33A by the impeller 38.

  Further, the ejecting part 222 also lifts the end portion of the bill BL upward from the sandwiching surface 33A by the curved part 241 at the curved position U2 which is the rear of the sandwiched position U1.

  As a result, the discharge part 222 forms a long inclined surface portion SL in the front and rear of the bill BL, and also forms a long curved surface SC in the vicinity of the boundary between the inclined surface portion SL and the parallel surface portion SP. (FIG. 6).

  And the discharge | release part 222 can advance the said banknote BL straight back like the 1st Embodiment by discharging | emitting the banknote BL in the curved state, and is finally integrated | stacked on the stage 25. Can be stacked neatly above the existing bills BL.

  In particular, the bending portion 241 can freely rotate the roller 242 so that the bill BL can be lifted with little sliding friction with the bill BL traveling in the backward direction. There is no harm.

  At this time, since the discharge unit 222 can transport the bills BL more smoothly than in the first embodiment, the discharge speed into the accumulation space 21A can be increased, and the curved shape can be maintained and just behind. While traveling, the building stopper 23 can be made to collide.

  With respect to other points as well, the discharge unit 222 according to the third embodiment can achieve the same operational effects as the discharge unit 22 according to the first embodiment.

  According to the above configuration, the discharge unit 222 according to the third embodiment holds the bill BL on the holding surface 33A by the holding conveyance unit 33 at the holding position U1, and the impeller 38 and the bending position at the holding position U1. The end portion of the bill BL is lifted upward from the sandwiching surface 33A by the U2 bending portion 241. Further, the bending portion 241 makes the roller 242 abut against the bill BL, and rotates the roller 242 as it advances. As a result, the discharge unit 222 can lift the left and right end portions upward from the sandwiching surface 33A with almost no sliding friction immediately before discharging the bill BL into the stacking space 21A. While it can be discharged and the state in which the bending strength in the vertical direction is increased by the curved surface SC is maintained, the inside of the integrated space 21A can be slid to reach the building stopper 23. As a result, the discharge unit 222 can stack the discharged banknotes BL neatly on the existing banknotes BL stacked on the stage 25.

The discharge unit 322 is different from the discharge unit 22 in that it includes an upper conveyance guide 331 and a bending portion 341 instead of the upper conveyance guide 31 and the bending portion 41, but the other portions are configured similarly. Yes.

  Like the curved portion 41, the curved portion 341 is formed in a thin plate shape in the left-right direction, but the shape seen from the left-right direction is not trapezoidal, and has a triangular shape with the slope extending upward. Yes.

  Further, the apex on the rear upper side of the bending portion 341 reaches the upper side of the lower surface of the upper conveyance guide 331. That is, the height from the lower conveyance guide 32 of the bending portion 341 is higher than that of the first embodiment.

  Although the upper conveyance guide 331 is formed in a thin plate shape in the vertical direction like the upper conveyance guide 31 as a whole, a groove portion 331A is formed at a location facing the curved portion 341 at the rear end portion of the lower surface. .

  The groove portion 331 </ b> A has an inclined surface that gradually increases toward the rear side at a rear end portion of the lower surface of the upper conveyance guide 331, with a certain space between the inclined portion of the curved portion 341, and the curved portion 341. A laterally facing triangular columnar groove space is formed by the left and right side surfaces spaced apart from each other by a certain distance.

  With this configuration, when the discharge unit 222 transports the bill BL backward, the discharge unit 222 abuts the end portion of the bill BL on the bending portion 341 and lifts the end portion of the bill BL upward.

  At this time, the upper conveyance guide 331 hardly causes sliding friction with the banknote BL by escaping the banknote BL lifted upward by the bending portion 341 to the groove section 331A.

  For this reason, the discharge | release part 322 can discharge | release the said banknote BL into the accumulation | aggregation space 21A in the state which formed the curved surface SC long before and behind in the banknote BL similarly to 1st Embodiment.

[4-2. Operation and effect]
In the configuration described above, the discharge unit 322 according to the fourth embodiment clamps the bill BL on the clamping surface 33A (FIG. 5A) by the stacking roller 34 and the pressure roller 36 of the clamping transport unit 33 at the clamping position U1. At the same time, the end portion of the banknote BL is lifted above the clamping surface 33A by the impeller 38.

  In addition, the discharge unit 322 also lifts the end portion of the bill BL upward from the holding surface 33A by the bending portion 341 also at the bending position U2 which is the rear of the holding position U1.

  As a result, the discharge part 322 forms a long inclined surface portion SL in the front and rear of the bill BL, and also forms a long curved surface SC in the vicinity of the boundary between the inclined surface portion SL and the parallel surface portion SP. (FIG. 6).

  And the discharge | release part 322 can advance the said banknote BL straight back like the 1st Embodiment by discharging | emitting the banknote BL in the curved state, and is finally integrated | stacked on the stage 25. Can be stacked neatly above the existing bills BL.

  In particular, the discharge portion 322 can increase the height from the lower conveyance guide 32 of the bending portion 341 by forming the groove portion 331A at a position facing the bending portion 341 in the upper conveyance guide 331. BL can be lifted higher.

  At this time, since the discharge portion 322 can greatly bend the curved surface SC, the discharge portion 322 can maintain a curved shape for a long time after being released into the accumulation space 21A, and while proceeding directly behind. It can be made to collide with the bill stopper 23.

  Moreover, since the discharge | release part 322 hardly contacts or slides the banknote BL on the upper conveyance guide 331, it does not reduce the discharge speed of the banknote BL, and does not damage the banknote BL.

  With respect to other points as well, the discharge part 322 according to the fourth embodiment can achieve the same effects as the discharge part 22 according to the first embodiment.

The end portion of the bill BL is lifted upward from the sandwiching surface 33A by the U2 bending portion 341. Moreover, the upper conveyance guide 331 avoids contact | abutting and sliding with the banknote BL by the groove part 331A. As a result, the discharge unit 322 can lift the left and right end portions sufficiently above the sandwiching surface 33A immediately before discharging the banknote BL into the stacking space 21A. While maintaining the state in which the bending strength is increased, the inside of the accumulation space 21 </ b> A can be slid to reach the building stopper 23. As a result, the discharge unit 322 can stack the discharged banknotes BL neatly on the existing banknotes BL stacked on the stage 25.

[5-2. Operation and effect]
In the above configuration, the discharge unit 422 according to the fifth embodiment lifts a part of the banknote BL upward by the bending section 41 as in the first embodiment, and other parts of the banknote BL. Is pushed downward by the downward pushing portion 441.

  Thereby, since the discharge | release part 422 can form more curved surfaces SC than 1st Embodiment in banknote BL, in the state which further raised the bending strength to the up-down direction in the said banknote BL, integration space Can be released into 21A.

  For this reason, the bills BL released from the discharge unit 422 can travel straight backward as in the first embodiment, and after being bounced back to the bill stopper 23, are finally accumulated on the stage 25. It can be stacked neatly above the existing bills BL.

  With respect to other points as well, the discharge unit 422 according to the fifth embodiment can achieve the same operational effects as the discharge unit 22 according to the first embodiment.

As a result, the discharging unit 422 can stack the discharged banknotes BL neatly on the existing banknotes BL stacked on the stage 25.

[6. Sixth Embodiment]
In the sixth embodiment, as shown in FIG. 15 corresponding to FIG. 4, the bill BL is discharged into the accumulation space 21 </ b> A by a discharge portion 522 instead of the discharge portion 22 according to the first embodiment. ing.

[6-1. Configuration of discharge part]
Although the discharge part 522 is different from the discharge part 22 in that it has a bending part 541 instead of the bending part 41, the other parts are configured in the same manner.
