Description

  The present invention relates to a recycle-type banknote storage device provided with a deposit and withdrawal function for storing and paying out banknotes as change, and an improvement in a banknote handling device.

A recirculating-type banknote storage device with a depositing function to accept inserted bills and a dispensing function to pay out deposited bills as change or withdrawal is handling bills such as various vending machines, depositing and dispensing devices, and money changing machines. It is equipped with the device, this recirculation type banknote storage device is configured to store banknotes prepared at the start of business or banknotes inserted during operation by denomination, and pay it out as change if necessary. Is known (Patent Document 1).
The bill recirculation device disclosed in Patent Document 1 has entered a backup plate on which bills are loaded, two pushing members that move up and down on the backup plate and hold bills transferred onto the backup plate, and each pushing member. Cooperation of a bill storage guide member for transferring bills (deposited bills) to the backup plate side and a feed roller for removing the stacked bill bundles on the backup plate in the dispensing direction by rotating in contact with the top bill. Thus, in the bill recirculation device configured to deposit or withdraw bills, the pushing member has a configuration in which the position of the rear end in the depositing direction is extended beyond the rotation axis of the feeding roller in the dispensing direction. Thus, it is possible to prevent the trailing end of the banknote bundle on the backup plate from rising.
The dispensing roller is means for contacting the stacked banknotes on the backup plate through the opening between the two pushing members and dispensing the same in the dispensing direction, and at the time of dispensing, each pushing member exceeds the rotation axis of the dispensing roller. It is necessary to evacuate upward. For this reason, in Patent Literature 1, both ends of the rotation shaft of the feeding roller are supported in a double-supported state by support members provided on a top plate or the like, thereby avoiding interference between the feeding roller shaft and the rear portion of the pushing member.

Next, FIG. 6 is a schematic view for explaining a problem of the bill recirculation device provided with the sweeper.
The bill recirculation device 200 includes a bill storage unit 201, a forward and reverse rotatable paper feed roller group 250 for moving bills bidirectionally between the bill storage unit and the transport path, a motor and a gear for driving the paper feed roller group. A drive mechanism (not shown) such as a group and control means (not shown) are provided.
The banknote storage unit 201 has a backup plate 202 on which the deposited banknotes P are loaded and which can be moved up and down, and can be moved up and down to push the deposited banknotes P1 deposited on the backup plate 202, and the bills pass through. Pushing member 210 having an opening for use, and a bill storage guide member 220 located above the backup plate 202 and relatively moving forward and backward in the opening for passing the bill when the pushing member 210 moves up and down, and guiding the transport of the bill. And an elastic member 225 for urging the backup plate in the ascending direction.
The paper feed roller group 250 is in contact with the upper surface of the bill on the backup plate 202 and rotates in the dispensing direction to dispense the uppermost bill, and a pair of separation rollers (friction roller 252a, stop roller 252b). Etc. are provided.

The rotation shaft 251a of the feeding roller 251 and the swing shaft that swings the bill storage guide member 220 in the vertical direction are common.
A sweeper 253 having a thin plate-like blade 253a made of an elastic material (rubber) projected radially from the center is fixed to the rotation shaft of the lower stop roller 252b. The blades of the sweeper are arranged at both ends in the axial direction that do not interfere with the friction roller 252a and the stop roller 252b, and are configured so as to suppress the rising of the trailing end of the bill in the bill storage unit by the leading end of the blade.

In the deposit standby position shown in FIG. 6, the pushing member 210 descends, contacts the top surface of the banknote bundle P on the backup plate 202, and presses it down, thereby forming an accommodation space for the deposited banknote P1 on the pushing member. . In this state, the deposited paper currency P1 is stored in the storage space by rotating the feeding roller 251 and the friction roller 252a in the payment direction indicated by the arrow. Subsequently, by raising only the pushing member 210, the deposited bill P1 relatively passes through the bill passing opening provided in the pushing member and is transferred onto the bill bundle P loaded on the backup plate.
When shifting from the deposit standby position shown in FIG. 6 to a dispensing position (not shown), the uppermost surface of the banknote bundle P on the backup plate is moved by moving the pushing member 210 further to the raised position than the deposit standby position. It is brought into contact with the feeding roller 251. By rotating the feeding roller 251 and the friction roller 252a in the feeding direction in this state, the uppermost banknote is fed from the banknote storage unit 201 to the outside.

  The bills sandwiched between the backup plate and the pushing member 210 by protruding the tips of the individual blades 253a into the bill storage unit 201 in the process of rotating in the counterclockwise direction during the deposit standby shown in FIG. The rear end of the banknote having a kinking tendency, a bulging tendency, or the like in the bundle P is pressed down. If the trailing edge of the banknotes on the backup plate is raised, the trailing edge of the loaded banknotes may be hampered by the sweeper blades 253a because the trailing edge of the banknotes may collide with the subsequent deposited banknotes or cause a jam. , The following banknotes can smoothly enter the accommodation space on the banknote holding member by the separation roller pair 252a and 252b.

However, when the blade continues to hit the rear end of the deposited banknote P1 on the pushing member 210, a strong frictional force is generated at the contact surface between the uppermost banknote P1-1 and the blade, so that only the uppermost banknote is entirely toward the sweeper. It slides and its rear end bends (bends) downward. The trailing end of the curved top bill drops into the gap S1 between the trailing end of the deposited bill P1 located below and the bill storage unit inner wall 230, causing a poor storage state. If a storage failure state occurs on the pushing member, a transfer failure on the backup plate or a loading failure on the backup occurs. If a stacking failure occurs in a state where the trailing end of the stacked banknotes falls into the gap on the backup plate, it becomes difficult to normally feed the banknotes with the feeding roller at the time of dispensing. In particular, when the trailing end of the deposited banknote that has fallen into the gap S1 falls downward beyond the trailing end 210A of the pushing member, the improper stacking state becomes more serious.
In particular, since the sweeper rotates integrally with the separation roller 252b, when the rotation speed of the separation roller is high, the rotation speed of the sweeper also increases, and the draw-in force (frictional force) increases, thereby increasing the risk of poor storage. .

Next, FIG. 7 is an explanatory diagram showing a state in which a banknote on the backup plate is pulled out by an illegal act by an administrator or the like. Since there is a gap S2 between the rear end 210A of the pushing member and the bill storage unit inner wall 230, a thin plastic plate or the like (illegal tool) 240 to which an adhesive is adhered via the gap S2 is moved upward as shown in the figure. The paper money can be extracted by inserting the paper money into the paper money storage unit and sucking and pulling out the paper money on the backup plate. Such misconduct is mainly caused by the existence of the gap S.
In the case where the deposit port of the bill handling device is disposed immediately adjacent to the sheet feeding roller group 250, the above-described misconduct is likely to be performed.

In recent years, since the demand for recirculating-type banknote storage devices 200 to be converted into cassettes and used as safes for cash management and transportation in the cassette state has become stronger, the banknotes from the banknote depositing / dispensing port of the banknote storage unit 201 to internal banknotes have been required. Fraudulent approaches are even easier.
In the case where a shutter is installed at the deposit / withdrawal port in order to prevent such misconduct, there is a tendency that the number of mechanical components increases, the structure becomes complicated, the cost increases, and the weight of the cassette which is required to be reduced in weight is increased.

Patent Document 1 discloses a configuration in which the rear portion of the pushing member extends in the dispensing direction beyond the rotation axis of the feeding roller so as to prevent the rear end portion of the banknote bundle on the backup plate from rising. A disclosed configuration is disclosed. However, the rear end of the pushing member is terminated only before the rear end of the deposited bill on the pushing member, and the problems shown in FIGS. 6 and 7 cannot be completely solved.
That is, since the rear end of the pushing member does not fill the gap S1 between the trailing edge of the stacked banknotes on the pushing member and the inner wall of the banknote storage unit, the rear end of the uppermost banknote pulled out rearward by the sweeper is this rear end. It was not possible to prevent falling down from the gap.

In addition, for the same reason, it is possible to illegally extract the banknotes already loaded on the backup plate via the gap S2 to the outside of the banknote storage unit.
Further, in Patent Literature 1, both ends of the rotation shaft of the feeding roller are rotatably supported by bearings supported by a support member positioned above the bill storage unit. Therefore, it is necessary to largely remodel the existing device configuration, and therefore, improvement in this point has been demanded.

The recirculation type banknote storage device 1 has a depositing function for receiving inserted banknotes and a dispensing function for dispensing stored banknotes as change and withdrawal, and includes various vending machines, depositing and dispensing devices, and currency exchange machines. Etc. are installed in a bill handling device.
The recirculation-type banknote storage device 1 communicates with a transport path capable of transporting bills inserted from a bill depositing unit (not shown) provided in a bill handling device in both a storing direction and a dispensing direction, and is transported along the transport path. It is means for storing (paying) received banknotes or feeding them out to the transport path. In the present apparatus, a bill is conveyed along the longitudinal direction with one longitudinal edge at the top.
The recirculation-type banknote storage device 1 includes a banknote storage unit 2 that stores transported banknotes in a vertically stacked state, and a banknote between a banknote storage unit and a transport path in a dispensing direction and a depositing direction. The paper feed roller group 50 to be moved in the direction, the sweeper 55, the banknote storage 70 having the banknote storage unit 2 therein, the paper feed roller group 50, motors for driving other movable parts, gear groups, and the like are not shown. The vehicle includes a drive mechanism and control means for controlling the drive mechanism.
When the recirculation-type banknote storage device 1 is configured to be detachable from the banknote handling device in the form of a cassette, part or all of the drive mechanism is provided on the banknote handling device side.

The recirculation-type banknote storage device 1 vertically stacks (stacks) a banknote storage 70 provided with a banknote loading / unloading section 72 and banknotes P transported from the banknote loading / unloading section 72 into the banknote storage along the longitudinal direction. A backup plate 3 urged upwardly and elastically upward, a pair of pushing members 10 which move up and down on the backup plate to press the upper surfaces at both ends in the width direction of the stacked banknotes P, and an opening between the pair of pushing members. And a bill storage guide member 20 for transferring the deposited bills P1 on the pair of pushing members 10 onto the backup plate when relatively descending and moving inside the opening, and a bill above the backup plate. The banknotes are arranged so as not to interfere with the storage guide member, and contact the upper surface of the stacked banknotes through the opening 11 and rotate in the unloading direction to transfer the banknotes to the banknote transfer unit It includes a feeding roller 51, a to.
Further, at least a part of the free end-like rear portion (rear end portion) 10a of the two pushing members 10 is provided with a gap S (S1) between the rear end portion of the deposited bill P1 on the pushing member and the bill storage inner wall 74. ) Protrudes (positions) inside.
Here, the gap S refers to a gap between the rear end of the deposited banknote P1 on the push-in member and the bill storage box inner wall 74 (gap S1 in FIG. 6), and a rear end of the backup plate (backup). It may refer to a gap (gap S2 in FIG. 7) between the stacked banknotes P on the plate (the rear end) and the banknote storage inner wall 74. That is, in the present invention, the rear portion of the pushing member protrudes along the boundary between the gap S1 in FIG. 6 and the gap S2 in FIG.

Bill storage guide member 20, the pivot shaft 20A of the payment rearward end (posterior) are swingably supported in the vertical direction, the pivot shaft 20A of the banknote storage guide member 20 has a pair of pushing members 10 It is arranged at a position where it does not interfere with the rear part 10a of the pushing member when it is raised.
In this example, the swing shaft 20A is fixed in a state protruding from the side surface of the bracket 60 of the feeding roller 51, and the bill storage guide member 20 is pivotally supported by the swing shaft 20A so as to be able to swing vertically. ing.
The banknote storage unit 2 located in the banknote storage box has a backup plate 3 on which the deposited banknotes are loaded and which can move up and down, an elastic member 4 for urging the backup plate upward, and an integrated unit on the backup plate. And a pair of pushing members 10 which are vertically movable and which are arranged in parallel and opposed to each other via an opening 11 for passing bills, and which are located above the backup plate 3 for passing bills when the pushing members 10 move up and down. A bill storage guide member 20 that relatively advances and retreats in the opening 11 and contacts the upper surface of the bill at the lower surface to guide the bill is disposed.

Each push-in member 10 is integrally formed in a horizontal positional relationship with the opening 11 interposed therebetween, a front part in the deposit direction (left side in the drawing) is connected, and a rear part (rear end part in the deposit direction) 10a. Has a free-end shape. The rear portion 10a of each push member protrudes rearward beyond the rear end of the deposited bill P1 (stacked bill P on the backup plate) on the pushed member, and the rear end of the deposited bill and the inner wall of the bill storage 70 (rear portion in the deposit direction). It is configured to partially close the lower part of the gap S1 formed between the inner wall (the inner wall) 74. That is, the rear portion 10a of the pushing member protrudes (positions) into the gap S1 to prevent the bill end from entering the gap or passing through the gap (FIGS. 4 and 5). Further, even when a plurality of deposited banknotes are stacked on the pushing member, even if the rear end of the uppermost deposited banknote hangs down from the rear of the bundle of deposited banknotes lower than that by the action of the sweeper (FIG. 6) Since the pushing member does not hang down further beyond the rear end of the pushing member, the subsequent transfer operation onto the backup plate does not become defective.
Each push-in member 10 is a means for holding the deposited bills received at the deposit standby position on the upper surface thereof, and pressing down on the upper surface of the loaded bills when it is relatively lowered on the backup plate, thereby pressing it.
Each pushing member 10 is integrally driven up and down by a lifting mechanism including a motor, a pulley, a belt, and the like.

The paper feed roller group 50 is disposed in contact with a bill carrying-in / out section 72 provided in the bill storage 70.
On the upstream side of the paper feed roller group 50, a paper feed sensor 30 for detecting whether or not the dispensing is completed when dispensing the banknote from the banknote storage unit 2 is arranged. Based on the detection signal, the control means drives the paper feed roller group 50, the backup plate 3, the pushing member 10 and the like at a predetermined timing.

In the present embodiment, each pushing member 10 is formed of a narrow band-shaped member (bar-shaped member) having a flat lower surface, and these members are arranged in parallel and opposed to each other at a predetermined interval (opening 11). The free end-shaped rear portions (rear end portions) 10a of the pushing members 10 are pushed into the vertically elongated slits (fitting holes) 74a provided in the corresponding inner wall (side wall) 74 of the banknote storage 70, respectively. The gap S between the bill rear end portion on the member (the trailing edge of the stacked bills on the backup plate) and the bill storage inner wall 74 is configured to be partially closed by the pushing member rear portion 10a.
In the present example, the narrow portion 10a 'is further projected from the push member rear portion 10a, and the narrow portion is inserted into the slit 74a so as to be guided in the vertical direction. However, the narrow portion is not essential, and the rear portion 10a is not required. What is necessary is just to be able to protrude backward beyond the banknote storage inner wall and to be able to move up and down.

By extending the rear portion 10a of each push member to the extent that it fits into the slit 74a of the bill storage inner wall, each push member 10 interferes with the rear portion 10a when it rises to the dispensing position in FIG. The drive shaft of the feeding roller 51 and the swing shaft (rotating shaft) 20A of the bill storage guide member 20 where the fear is generated are prevented from interfering with the pushing members 10.
It is desirable that the rear portion 10a of the pushing member be extended to such an extent that the rear portion 10a of the pushing member is fitted into the slit 74a provided in the banknote storage inner wall 74. May be configured to protrude (overhang) above the gap S by approaching at a distance. In short, the rear portion 10a only needs to protrude to such an extent that it can be prevented from entering the gap of the trailing edge of the deposited banknote and being pulled out through the gap of the banknote at the time of fraud.

The paper feed roller group 50 rotates in the dispensing direction by contacting the upper surface of the stacked banknotes P on the backup plate 3 via the opening 11 when the backup plate 3 is raised to the dispensing position in FIG. And a reversible feed-out roller 51 for dispensing the uppermost banknote, and a separation roller pair 52. The separation roller pair 52 includes an upper friction roller (upper transport roller) 53 that rotates forward and backward, and a lower stop roller (double feed prevention roller) 54. The stop roller 54 is stopped when the bill is fed, or is rotating at a low speed in the return direction.
The friction roller (upper transport roller) 53 and the stop roller (double feed prevention roller) 54 have their respective rotating shafts supported by bearings provided on, for example, a side plate or a top plate (not shown), and are driven by a motor (not shown). It is driven to rotate by force.

A sweeper 55 is fixed to a position on the rotation shaft 54a of the stop roller 54 that does not interfere with the stop roller. The sweeper 55 includes a center member 56 fixed to the rotating shaft 54a, and a thin plate-like elastic blade 57 projecting radially from the center member 56.
The sweeper 55 causes the individual elastic blades 57 to sequentially project into the bill storage unit 2 in the process of rotating in the counterclockwise direction during the standby for depositing as shown in FIG. Then, the rear end of the bill is shaped by hitting the rear end downward, and the rear end of the banknote having a bending habit or a bulging habit on the pushing member is pressed down. If the trailing end of the deposited bill on the push-in member is raised, it may collide with the following deposited bill and hinder the entry or cause a jam. By pressing down the portion, the subsequent bill can be smoothly entered into the accommodation space on the bill holding member by the separation roller pair 52.

As shown in FIGS. 1, 2, and 3, one end (rear end in the depositing direction) of the feeding roller 51 is swingably supported by a rotation shaft 53a of an upper friction roller (upper transport roller) 53. The bracket 60 is rotatably supported by the rotating shaft 51a near the other end (tip in the payment direction). That is, the feeding roller 51 is supported by the bracket 60 which moves up and down with the rotation shaft 53a as the swinging shaft 60A, and comes into contact with a proper position on the upper surface of the banknote on the backup plate when the backup plate 3 is raised to the dispensing position. It is configured to be able to. According to this configuration, there is no room for the rear portion 10a of the pushing member 10 that moves up and down in the bill storage unit to interfere with the swing shaft 60A of the feeding roller 51.
The feeding roller 51 is driven to rotate by transmitting a driving force from a motor (not shown) through a pulley, a timing belt, and the like (not shown) supported by the bracket 60 and the like.

In addition, the bill storage guide member 20 pivotally supports an end portion (rear end portion on the receiving side) near the paper feed roller group 50 by a rotating shaft 53 a of an upper friction roller (upper transport roller) 53 and swings vertically. You may be comprised freely. That is, the bill storage guide member 20 may be configured to be vertically movable using the rotation shaft 53a as the swing shaft 20A. In this case, there is no room for the rear portion 10a of the pushing member 10 that moves up and down in the bill storage unit to interfere with the swing shaft 20A of the bill storage guide member 20.
As described above, the swing shaft 20A of the bill storage guide 20 and the swing shaft 60A of the bracket 60 may be shared with the rotation shaft 53a of the upper friction roller 53. Here, "commonly used" means that the axis of each of the swing shafts 20A and 60A matches the axis of the rotating shaft 53a of the upper friction roller 53.

The characteristic configuration of the present invention is that at least the depositing-side rear portion 10a of the pushing member 10 reaches the inner wall 74 of the bill storage box over the trailing edge of the bill on the pushing member (or the stacked bill on the backup plate) ( (Or close to) the swinging shaft 20A of the bill storage guide member, which is a member that may interfere with the elevating path of the extended rear end of the pushing member, and the drive shaft 51a of the feeding roller 51. Is retracted out of the elevating route.
In this embodiment, although an example configuration in which the bill storage guide member 20 swingably supported by the bracket 60 by supporting the pivot shaft 20A of the banknote storage guide member 20 by the side of the bracket 60, which is This is only an example, and the rotation shaft 53a of the upper friction roller 53 does not have to be shared as a swing shaft if each swing shaft is provided at a position that does not interfere with the extended rear portion 10a of the pushing member 10. For example, each swing shaft may be supported by a top plate, side plates, and other members (not shown) of the present apparatus.

As described above, the configuration may be such that the swing shaft 60A is shared with the rotation shaft 53a of the upper friction roller 53 (upper transport roller).
Note that the rotation shaft 51a of the feeding roller 51 is supported by the bill storage guide 20 or supported by a bearing fitting provided on a top plate or the like as shown in Patent Document 1 so that the rotation shaft 51a and the rear portion of the pushing member are formed. In this case, only the swing shaft 20A of the bill storage guide member 20 may be retracted out of the elevating path of the pushing member rear portion 10a.

<Payment operation>
The control unit drives a lifting mechanism (not shown) to hold the pushing member 10 at the lowest position, a storage position (not shown), a deposit standby position above the storage position (FIG. 2A), and By raising and lowering between a dispensing position (FIG. 2B) above the standby position and an uppermost position (not shown) further above the dispensing position and stopping at each position, the bill Payment (storage) and payment of stored banknotes are performed, respectively.
In the deposit standby position shown in FIG. 2A, the pair of pushing members 10 descends, contacts the top surface of the banknote bundle P on the backup plate 3 and presses it down, so that the bills P <b> 1 are deposited on the pushing member. Form an accommodation space. By rotating the friction roller 53 in the deposit direction indicated by the arrow in this state, the deposited bills P1 are sequentially accommodated in the accommodation space. Subsequently, by raising the pushing member 10, the backup plate 3 is raised by the urging force of the elastic member 4, and the upper surface of the central portion of the deposited bill is pressed by the bill storage guide member 20, and the deposited bill P1 is pushed. Are passed through the inside of the bill passage opening 11 provided on the backup plate and transferred onto the bill bundle P stacked on the backup plate. Each pushing member 10 presses the upper surface of both ends of the deposited bill onto the loaded bill P by descending again.

<Payout operation>
In the dispensing position shown in FIG. 2B, when the pushing member 10 is positioned above the lowermost portion of the feeding roller 51 (the position where the pushing member 51 contacts the upper surface of the stacked banknotes), the uppermost surface of the banknote bundle P on the backup plate. The biasing force of the elastic member 4 is set so that the bills of the present embodiment come into contact with the feeding roller 51 with an appropriate pressure. Further, as the number of stacked banknotes on the backup plate 3 decreases, the backup plate is pushed up by the elastic member to adjust the separation pressure. By rotating the feeding roller 51 and the friction roller 53 in the feeding direction indicated by the arrow in this state, the uppermost banknote is fed from the banknote storage unit 2 to the outside. At this time, the stop roller 54 as the double feed prevention means stops the rotation or rotates in the return direction shown by the arrow, so that the lower one of the double fed banknotes is Return to

<Characteristic actions and effects>
In the present invention, the rear portion (rear end portion) 10a of the pushing member 10 exceeds the rear end portion of the deposited bill on the pushing member (or the rear end portion of the stacked banknotes on the backup plate or the rear end portion of the backup plate). The lower part of the gap S1 between the rear end of the deposited bill P1 and the bill storage inner wall by protruding toward the inner wall 74 of the bill storage, and the stacking bill P1 on the backup plate and the bill storage inner wall. The upper portions of the gaps S2 between them are closed. In addition, there is no interfering member in the elevating path (especially the ascending path) of the rear portion 10a of the pushing member. For this reason, the rear part of the pushing member has a length exceeding the rear end of the deposited banknote bundle.
In the present invention, the rear portions (rear end portions) of the pair of pushing members are each elongated beyond the rotation axis of the feeding roller, and the swing shaft 60A of the bracket 60 supporting the feeding roller and the bill storage guide member 20 are provided. The swinging shaft 20A does not interfere with the elevating path of each pushing member, so that the rear portions of the two pushing members are moved in the dispensing direction (rearward in the depositing direction) beyond the feed roller (rotary shaft) and the rear end of the backup plate. ) Can be extended.
Since the lower part of the gap S1 between the rear part of the deposited bill P1 on the pushing member 10 and the bill storage inner wall 74 is closed by the pushing member rear part 10a, as shown in FIG. Even if the banknote P1 is displaced rearward, there is no possibility that the rear end enters the gap S1 and causes a stacking failure. In particular, the trailing end of the deposited bill cannot be shifted downward beyond the trailing end of the push-in member, so that a defective loading state can be minimized.

In addition, as shown in FIG. 5, the gap S, which is a path connecting the rear portion of the loaded banknotes P on the backup plate and the bill carrying-in / out portion 72, is closed by the rear portion of the pushing member. It also becomes impossible to extract.
In addition, in order to completely prevent a fraudulent act of inserting a fraudulent tool from the bill carrying-in / out portion via the gap S2 and extracting the stacked bills on the backup plate, it is only necessary to partially close the gap S2 with the rear part of the pushing member. Instead, it is desirable to shift each component to the deposit standby position shown in FIG. 2A when various operations are completed, and to hold the deposit standby position when not operating. That is, when the push-in member is located above the height position of the banknote pay-in / pay-out path (the bill carry-in / out section 72), the fraud prevention effect by the rear portion of the push-in member cannot be exerted.
Thus, a fraud prevention mechanism such as a shutter is not required, and fraud can be easily prevented without increasing the number of parts, increasing the cost, and increasing the weight.

<Summary of Configuration, Function, and Effect of Invention>
The recirculation-type banknote storage device according to the first aspect of the present invention vertically moves a banknote storage 70 provided with a banknote loading / unloading section 72 and a banknote transported from the banknote loading / unloading section into the banknote storage along the longitudinal direction. A backup plate 3 that is stacked (laminated) and is elastically urged upward and that can be raised and lowered. A pair of backup plates 3 that rises and lowers on the backup plate and presses the upper surfaces at both ends in the width direction of the stacked banknotes P on the backup plate. The banknote which moves up and down the push member 10 and the opening 11 between the pair of push members relatively, and transfers the banknotes on the pair of push members to the backup plate 3 when descending relatively inside the opening. The banknote is disposed above the storage guide member 20 and the backup plate, contacts the upper surface of the stacked banknotes through the opening 11, and rotates in the dispensing direction to transfer the banknotes to the banknote transfer unit 7. Comprises, a feeding roller 51 to shift to.
Furthermore, the rotating shaft 51a of the feeding roller has a configuration that does not interfere with the elevating path of the two pushing members, and at least a part of the free-end-shaped rear portion 10a of the two pushing members is formed of the bill P1 on the pushing member. It is characterized in that it protrudes (positions) into a gap S1 (below the gap S1) between a rear end (back end of the banknote on the backup plate) and the banknote storage inner wall (repository side wall) 74. I do.

  Since the back edge of the backup plate 3 is moved up and down along the inner wall 74 of the banknote storage 70, a gap S1 is formed between the rear edge of the stacked banknotes P on the backup plate and the inner wall 74. Similarly, a gap S2 is also formed between the trailing edge of the deposited bill on the pushing member and the inner wall 74. For this reason, when the rear end of the bill on the pushing member is hit by the sweeper, the rear end of the bill bends downward and easily enters the gap S1, and when the bill enters, the transfer failure on the backup plate or the stacking failure may occur. Cause. Further, the gaps S1 and S2 allow the stacked banknotes on the backup plate to communicate with the banknote carry-in / out section 72 of the banknote storage, so that a banknote can be inserted from outside and the banknotes can be extracted.

In order to solve the above-mentioned problem, it is effective to extend the rear part of the pushing member 10 to close a part or all of the gap (FIG. 4). Note that at least a portion of the rear portion 10a of the pushing member protrudes (positions) into the gap S when the rear end (rear edge) is positioned within the gap, and when the rear end is This includes the case where the paper money storage is located beyond the gap inside the bill storage box inner wall (side wall) but the rear part other than the rear end is located in the gap.
When the recirculation-type banknote storage device is a cassette type, the configuration is detachable from the banknote handling device. In such a case, the administrator or the like removes the recirculating banknote storage device from the banknote handling device and transports or stores it.However, since the banknotes are stored in the immediate vicinity of the banknote loading / unloading section, illegal It is easy to remove the used bill.
According to the present invention, since the gap S is closed by the push-in member, it is possible to reliably prevent an illegal act by the administrator (FIG. 5).

The recirculating banknote storage device according to the second aspect of the present invention is characterized in that the rear portion 10a of the pushing member is further projected rearward beyond the banknote storage inner wall 74.
The rear end (rear end) 10a of the pushing member protrudes into the gap S (S1, S2) beyond the rear end of the deposited bill on the pushing member, so that the trailing end of the deposited bill enters the gap. However, it is possible to prevent the bill on the backup plate from being illegally withdrawn through the gap, but various patterns can be assumed as the protruding length. If the rear portion (rear end portion) 10a of the pushing member protrudes rearward beyond the inner wall of the banknote storage, the above-described problem can be reliably prevented (FIG. 4).

The recirculating banknote storage device according to the third aspect of the present invention is characterized in that a slit is formed on the inner wall of the banknote storage box so as to move up and down while a rear portion (rear end portion) of the pushing member is fitted.
As one of the methods for projecting the rear portion 10a of the pushing member rearward beyond the banknote storage inner wall, a slit for fitting the rear portion 10a to the banknote storage inner wall and guiding the vertical movement can be provided. .

The recirculation-type banknote storage device according to the fourth aspect of the present invention includes a bracket 60 that pivotally supports the pay-out roller 51 and supports the supply roller 51 so as to be vertically swingable, and the bracket is provided near the rear end in the payment direction. It is supported by a shaft 60A so as to be vertically movable, and the swinging shaft of the bracket is arranged at a position where it does not interfere with the rear ends of the pushing members when the two pushing members are raised.
If a structure in which the rotating shaft 51a of the feeding roller 51 is supported by the side walls of the bill storage box or cantilevered is adopted, the rotating shaft 51a protrudes in the axial direction and interferes with the lifting path of the pushing member. While supporting both ends of the short rotating shaft of the feeding roller, the rear end of the bracket in the payment direction is supported by the swing shaft 60A. Further, when there is a risk that the swing shaft 60A may interfere with the rear portion 10a of the pushing member, the swing shaft of the bracket is moved to a position where it does not interfere with the rear end of each pushing member when the two pushing members are raised. Deploy.

In the recirculating banknote storage device according to the fifth aspect of the present invention, the banknote storage guide member 20 has a rear end in the payment direction (rear portion in the payment direction) supported by a rocking shaft 20A so as to be vertically swingable. The swinging shaft of the storage guide member is characterized in that it is arranged at a position where it does not interfere with the rear part 10a of the pushing member when the pair of pushing members is raised.
The swinging shaft 20A of the conventional bill storage guide member 20 is disposed at a position different from the swinging shaft (60A) of the feeding roller, and in order to prevent interference between the swinging shaft 20A and the pushing member rear portion 10a. Needed to shorten the rear part of the pushing member. However, in the related art, the above problem has occurred because the rear portion of the pushing member is short enough not to reach the gap S. Therefore, in the present invention, the swing shaft 20A of the bill storage guide member is disposed outside the vertical path at the rear of the pushing member.
That is, since the pushing member moves up and down in a wide range from the lowermost position to the uppermost position, there is a possibility that the rear end portion extended when the pushing member rises may interfere with the swing shaft 20A of the bill storage guide member 20. .
If there is still a problem that the swing shaft 20A of the bill storage guide member interferes with the rear portion 10a by merely retracting the swing shaft 60A of the feeding roller from the lifting path of the pushing member rear portion 10a, the swing shaft 60A of the feeding roller is used. Is also retracted from the elevating path of the rear part 10a.

In the present invention, by disposing the swinging shaft 20A, which is located in the elevating path at the rear part of the pushing member and hinders elevating, outside the elevating path, the rear part of the pushing member is formed to extend and protrude into the gap S. , The gap can be at least partially closed. To close the gap here, by protruding the pushing member rear portion toward the gap side within the width dimension of the stacked banknotes, to prevent the rear end of the bill on the pushing member from bending downward and entering the gap, This means a configuration that prevents bills on the backup plate from being pulled upward through the gap. In other words, closing the gap does not necessarily mean closing the entire opening area of the gap, but as shown in the embodiment, the narrow pressing member protrudes into the opening area of the gap, enters the bill end, enters the bill. It means a configuration that blocks passage.
The position at which the swing shaft 20A is retracted may be any position as long as it is behind the elevating path at the rear of the pushing member in the depositing direction.
When the rotating shaft or the swinging shaft of the feeding roller 51 is at a position further retracted backward from the elevating path at the rear of the pushing member, only the swinging shaft countermeasure of the bill storage guide member needs to be taken. That is, as in the present invention, the swing shaft of the bill storage guide member may be retracted from the lifting path at the rear of the pushing member.

In the recirculating banknote storage device according to the sixth aspect of the present invention, an upper transport roller 53 and a lower transport roller 54 for nipping and transporting banknotes are arranged in the banknote loading / unloading section 72, and a swing axis of a banknote storage guide is provided. 20A and the swinging shaft 60A of the bracket are shared by the rotating shaft 53a of the upper conveying roller.
The rotating shaft 53a of the upper conveying roller 53 is located outside the ascending / descending path of the rear portion 10a of the pushing member, particularly, outside the raised position. In the present invention, the rotating shaft 53a is also used as the swing shafts 20A and 60A. By using the existing rotary shaft 53a, it is not necessary to add a new member, the configuration is simplified, and the existing device can be retrofitted.
Since the swing axis of the bill storage guide member and the feeding roller is shared with the rotation axis of the upper conveyance roller, it is possible to prevent an increase in the number of parts, and to modify the existing apparatus by retrofitting. As a result, the number of manufacturing steps and cost can be reduced.

According to a seventh aspect of the present invention, there is provided a bill handling device including the recirculation-type bill storage device according to any one of claims 1 to 6.
The recycle banknote storage device according to the present invention can be applied to various banknote handling devices such as various vending machines, depositing / dispensing devices, and currency exchange machines.
