Description

  The present invention relates to an improvement of a banknote handling device equipped in a currency handling device such as various vending machines, deposit / withdrawal devices, and money changers having a function of depositing / withdrawing money. In the reflux-type banknote handling apparatus provided with a plurality of reflux-type banknote storage units, the present invention relates to a technique for speeding up the operation of collecting all banknotes in one banknote storage unit or the like at the end of work. The present invention relates to a bill storage device suitable for a bill processing device.

Banknote processing devices with a deposit function that accepts inserted banknotes and a withdrawal function that dispenses banknotes as change or withdrawal are equipped in various vending machines, deposit and withdrawal devices, money changers, etc. The apparatus is equipped with a banknote storage unit for storing banknotes prepared at the start of business or banknotes inserted during operation in denominations.
In this type of banknote handling apparatus, when collecting all banknotes remaining in the apparatus main body at the end of work, etc., if the banknote bundles respectively stored in the denomination banknote storage unit are individually taken out of the machine However, it is necessary to make all the banknote storage parts cassette-type so that they can be taken in and out of the machine. However, such a configuration not only increases the size of the banknote storage part, but also makes the collection work complicated and long. Make time.

In order to cope with the problems as described above, for example, in a reflux-type banknote handling apparatus that conventionally handles, for example, a thousand-yen banknote, a 5,000-yen banknote, and a 10,000-yen banknote, a reflux-type banknote storage unit corresponding to each denomination of each banknote is provided. In addition, there is a thing in which the function of performing banknote access for replenishment / collection of banknotes is assigned to the 1,000-yen banknote storage unit.
The reflux-type banknote storage unit is used not only to store banknotes stored in advance at the start of business, but also to temporarily store banknotes inserted by the user during the operation of the apparatus, while using the banknotes as change etc. A bill storage unit of a type having a function of feeding out (discharging) to the outside is designated. Further, there are a loop type and a switchback type in the reflux type banknote storage unit. The loop method is a method in which the entrance (accepting direction) and the exit (feeding direction) of bills are different, and the switchback method is a method of receiving and delivering bills from the same entrance / exit.

FIG. 4 shows a configuration of a conventional switchback type reflux-type banknote processing apparatus.
This banknote processing apparatus 101 is roughly configured from a reflux-type banknote processing mechanism 102 and an exterior body 103 that houses the banknote processing mechanism.
The banknote handling mechanism 102 includes a plurality of banknotes of different denominations, or a deposit taking-in unit 104 that can accept one by one, and a conveyance path for carrying the banknotes received from the depositing-in unit 104 into the apparatus. 105, a transport mechanism 110 including a roller, a belt, a branch gate, a motor, a solenoid, and the like that generates and transmits a driving force for transporting bills along the transport path 105, and a downstream side of the deposit taking-in portion 104. Identification device 115 for determining the authenticity and denomination of banknotes placed on the transport path and fed one by one, and a first banknote connected to the transport path 105 and related to the first denomination (for example, A recirculation-type first banknote storage unit 120 that stores a 10,000-yen banknote in a freely removable manner, and a second banknote (for example, a thousand-yen banknote) connected to the transport path 105 and related to the second denomination. Reflux-type second that is housed freely A bill storage unit 122; a withdrawal holding unit 130 having a function of discharging bills out of the apparatus as change or the like and depositing and holding a plurality of bills; and a control means 140 for controlling them. Yes.

The deposit taking-in part 104 is provided with a separation / feeding mechanism for feeding a plurality of banknotes that have been batch-loaded into the transport path 105 while separating them one by one.
The transport mechanism 110 has a sorting transport function for feeding banknotes fed one by one from the deposit taking-in section 104 to the first or second banknote storage section 120, 122 in denomination, and the first or second And a function of conveying the banknotes sent out one by one from the banknote storage units 120 and 122 to the withdrawal holding unit 130. The transport mechanism 110 includes a roller, a belt, first and second branch gates 111 and 112 (not shown), a motor for driving these movable parts, a solenoid, and the like. By driving the roller, the belt, and the branch gate, each conveyance function can be realized at a predetermined timing.

The first banknote storage unit 120 is dedicated to the first banknote, for example, a 10,000 yen banknote, and has a reflux function for sending 10,000 yen banknotes once received via the transport path 105 to the transport path 105 one by one. Have.
The second banknote storage unit 122 is dedicated to the second banknote, for example, a thousand-yen banknote, and has a reflux function for sending the thousand-yen banknotes once received via the transport path 105 to the transport path 105 one by one. ing. The second banknote storage unit 122 is a cassette type that can be drawn out of the machine, and the first banknotes stored in the first banknote storage unit 120 are sequentially fed into the second banknote storage unit 122 at the end of work. By stacking at the above, all banknotes can be taken out to the outside by using the second banknote storage unit 122.
In addition, although the reflux-type banknote processing apparatus according to this conventional example is configured on the premise of miniaturization as much as possible, the direction changing portion by the branch gates 111 and 112 is a U-turn or the like having a small curvature. Since the curved conveyance is difficult, the direction changing portion by the branch gate has to be a curved path with a large curvature, and there is a limit to the reduction in the lateral width of the conveyance path 105.

At the time when the operation of the vending machine equipped with this bill processing device is finished, the bills stored in the first bill storage unit 120 are automatically transferred one by one to the second bill storage unit 122, The worker pulls out the second banknote storage unit 122 and collects the sales price (all banknotes).
As operation | movement which transfers and accommodates a banknote from the 1st banknote storage part 120 to the 2nd banknote storage part 122, for example, one 10,000 yen banknote from the banknote bundle stored in the 1st banknote storage part 120 is taken. After separating and feeding to the conveyance path 105 and moving to the point R on the conveyance path, reverse conveyance is performed, and the path is changed by the branch gate 112 and transferred to the second banknote storage unit 122.
In addition, since it is sufficient to set a predetermined number of thousand yen bills to be used as change in the second bill storage unit 122 at the start of work, it is possible to limit the number of access points to the bills by workers and improve security. At the same time, it reduces the burden on workers.

However, in the conventional switchback recirculation type banknote processing apparatus, when the collection operation is performed from the first banknote storage unit to the second banknote storage unit 122, one by one from the first banknote storage unit. There is a problem in that the collection time is prolonged because each bill sent to the transport path must be transported in reverse at the R point.
As an improvement measure for shortening the collection time, as shown in FIG. 5, the first banknote storage unit is provided by providing the triple branch gate 114 at the transfer path branch point connected to the entrance / exit of the second banknote storage unit 122. 120 stored banknotes can be successively transferred to the second banknote storage unit 122 one by one.
However, when the triple branch gate 114 is actually incorporated, a considerably large curvature is required for the curved conveyance of banknotes, and an extremely complicated and large conveyance mechanism is required. Cost was inevitable.

Japanese Patent Application Laid-Open No. 2002-260059 includes a denomination-type banknote storage section and a large-capacity replenishment / collection banknote storage section. At the end of work, all banknotes in each banknote storage section are stored one by one in the replenishment / collection banknote storage section. A banknote dispensing machine is disclosed in which all banknotes can be taken out from the replenishment / collection banknote storage by feeding them.
However, in this conventional example, the work of transferring a large amount of banknotes stored in each banknote storage unit one by one to the replenishment / collection banknote storage unit is required, so that the recovery operation takes a long time. There is. Moreover, since it is necessary to arrange a large replenishment / collection banknote storage part in the apparatus separately from a plurality of banknote storage parts, not only the mechanism for banknote storage and conveyance is complicated, but also the apparatus is large. There was a drawback of becoming. Moreover, since it is a loop-type reflux-type banknote processing apparatus using a denomination-type banknote storage unit that is separately provided with an inlet and an outlet for banknotes, it is a large-scale reflux-type banknote processing apparatus having a complicated transport path.
While demands for miniaturization of various banknote handling apparatuses are increasing, it is difficult to adopt a configuration that causes such an increase in size.
JP 2002-260059 A

As described above, in the banknote handling apparatus including a plurality of switchback type banknote storage units, it is necessary to transfer all banknotes remaining in each banknote storage unit one by one to one reflux-type banknote storage unit at the end of work. For this reason, there is a problem that the transport mechanism is enlarged and there is a limit to shortening the collection time. If a complicated and large transport mechanism such as a triple branch gate is added to shorten the collection time, there is a problem that the size and cost are further increased.
The present invention has been made in view of the above, and in a banknote handling apparatus provided with a plurality of reflux-type banknote storage units for each denomination, a large-sized apparatus is equipped with a special cassette dedicated for collection in addition to the banknote storage section. Refrigeration banknote processing apparatus capable of recovering banknotes from each banknote storage unit in one place in the shortest time at the end of work, etc. It aims at providing a bill storage device.
In particular, an object of the present invention is to provide a reflux-type banknote storage device capable of depositing banknote bundles in a lump sum in addition to depositing and dispensing one by one.

  In order to achieve the above object, the invention according to claim 1 is a banknote stacking mechanism and a banknote is introduced into the banknote stacking mechanism one by one or as a banknote bundle, or one banknote is stored in the banknote stacking mechanism. A banknote depositing / dispensing mechanism for paying out a banknote, wherein the banknote stacking mechanism is supported so as to freely move up and down between a raised dispensing position and a lowered receiving position, and a banknote is placed on an upper surface thereof. A stacking member that accumulates in a stacked state, an elastic member that elastically biases the stacking member upward, and a banknote or banknote bundle that has been introduced from the banknote depositing and dispensing mechanism by moving up and down above the stacking member A pusher that pushes against the upper surface of the stacking member; and a pusher lifting / lowering mechanism that lifts and lowers the pusher, wherein the bill depositing / dispensing mechanism rotates while nipping each other. An upper roller support portion that changes the distance between the upper roller and the lower roller by moving the upper roller up and down, and is pivotally supported by the fixed portion so as to be swingable in the vertical direction, and is associated with the upper roller support portion. A regulating arm having a front portion provided with a stopper for regulating a separation distance between the upper roller and the lower roller by combining, and a roller driving mechanism for driving the upper and lower rollers, The restricting arm lowers the stopper provided at the front by pushing up the rear part by the pusher in the raised position, thereby restricting the separation distance between the upper roller and the lower roller to the minimum, while the pusher When the lower part is lowered, the rear part is lowered to raise the stopper so that the separation distance between the upper roller and the lower roller is increased to the maximum value. It is characterized in that is.

  In a switchback recirculation type banknote storage device that requires not only depositing / withdrawing banknotes one by one but also banknote bundles, a nip between a pair of rollers that conveys the banknotes or banknote bundles while nipping them. It is difficult to set the interval and nip force. In the present invention, the upper roller and the lower roller are configured to be movable up and down, and the upper roller can be raised by using a stopper. In other words, the upper roller's vertical movement range is restricted to a minimum by the stopper when dispensing only one banknote, while the upper roller's vertical movement range is set when depositing not only one banknote but also a banknote bundle. The stopper is retracted so as to expand to an extent that allows passage of a predetermined number of banknote thicknesses. Moreover, since the up-and-down swing of the regulating arm provided with the stopper at the front is linked to the operation of the pusher having a function of pushing down or raising the banknote stacking member, the banknote stacking member is lowered to the receiving position. Only when the stopper is in the raised position, it acts to expand the movable range of the upper roller.

According to a second aspect of the present invention, in the first aspect, the upper roller is a friction roller, and the lower roller is a reverse roller, and when a single banknote or banknote bundle is introduced into the banknote stacking mechanism. The upper roller and the lower roller are both rotated in the introduction direction, while at the time of bill feeding, the upper roller is reversely rotated in the feeding direction and the lower roller is rotated in the introduction direction so that the lower multi-fed bill is It is configured to return to the deposition member side.
The cooperation of the friction roller and the reverse roller can effectively prevent the bill double feed.

The reflux-type banknote processing apparatus according to the invention of claim 3 is configured to receive a plurality of banknotes of different denominations at a time, or a banknote received from the banknote receiving section. A transport path for transporting into the apparatus main body, a transport mechanism for generating a driving force for transporting banknotes along the transport path, and a first banknote connected to the transport path and relating to the first denomination A switchback recirculation type first banknote storage unit that freely accommodates, and a switchback recirculation type second bank that is connected to the transport path and accommodates the second banknote relating to the second denomination freely. A banknote storage unit, a temporary storage unit that receives and deposits banknotes transported via the transport path one by one, and sends the accumulated banknote bundles to the transport path at once, and a control for controlling these A reflux-type banknote handling apparatus comprising: The control means sends out the first banknotes in the first banknote storage part one by one and deposits a predetermined number of sheets in the temporary storage part, and then transfers the first banknote bundle in the temporary storage part to the second banknote. All the first banknotes stored in the first banknote storage section are transferred to the second banknote storage section by repeating the operation of collectively transporting the banknote storage section into the second banknote storage section. Is constituted by the reflux-type banknote storage device according to claim 1 or 2.
By using one of the reflux-type banknote storage units that store banknotes by denomination as the recovered banknote storage unit, the overall shape of the apparatus can be reduced in size. Furthermore, since it is possible to simplify and reduce the size of the conveyance path and the conveyance mechanism by adopting a configuration in which the collection operation of the banknote bundle unit using the temporary storage unit can be performed, the overall shape of the apparatus can be further reduced. Can do.

According to the present invention, in a configuration in which a denomination type switchback reflux type banknote storage unit is provided, when collecting banknotes stored in one banknote storage unit into the other banknote storage unit, it has only an accumulation function. Since the batch conveyance is performed with the temporary holding unit having a simple configuration, the transfer processing time can be shortened without increasing the size of the apparatus. That is, using a temporary storage unit having a simpler structure than the reflux-type banknote storage unit, the stored banknotes to be transferred are fed to the temporary storage unit one by one and accumulated, and the stacked banknote bundle is directly placed on the same transport path. Since it is fed out and bundled and conveyed to the banknote storage part that also serves as the collected banknote storage part, the time required for the banknote transfer process can be shortened.
The switchback recirculation type banknote storage device has a mode for accepting a single banknote or banknote bundle that has been transported, in addition to a mode in which banknotes accumulated on the banknote stacking member are fed out one by one. is doing. For this reason, it is necessary to change the interval of the roller pair for depositing / withdrawing according to the thickness of the banknote bundle to be deposited. In the present invention, in the banknote receiving mode, the interval between the rollers is narrowly regulated so that only one banknote can pass through, while in the mode in which the banknote bundle is also received, the upper roller moves up and down according to the banknote pressure. It is possible to cope with both modes by relaxing the regulation so that it can move. Moreover, since the mode switching using the stopper is linked to the vertical movement of the pusher that holds the banknotes on the banknote stacking member, it is possible to construct a reflux-type banknote storage device while reducing the size without complicating the configuration. it can.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1 is a schematic configuration diagram of a banknote handling apparatus according to an embodiment of the present invention.

The banknote handling apparatus 1 is schematically configured from a reflux-type banknote handling mechanism 2 and an exterior body 3 that houses the banknote handling mechanism 2 therein.
The banknote handling mechanism 2 transports a plurality of banknotes of different denominations at a time, or a banknote accepting unit 4 that can accept each banknote and a banknote received from the depositing unit 4 into the apparatus main body. A path 5, a transport mechanism 10 including a motor, a solenoid, a roller, a belt, and a gate for generating and transmitting a driving force for transporting bills along the transport path 5, and immediately downstream of the deposit taking-in portion 4. The identification device 15 for determining the authenticity and denomination of bills arranged on the transport path on the side and fed one by one, and the first banknote connected to the transport path 5 and relating to the first denomination A switchback recirculation-type first banknote storage unit (recirculation-type banknote storage device) 20 that is detachably accommodated, and a transport path 5 are connected to allow the second banknote relating to the second denomination to be freely inserted and removed. Switchback reflux-type second banknote storage section (reflux-type banknote) (Payment device) 25, banknotes that have been transported via transport path 5 are received and deposited one by one, temporary banking unit 30 that collectively sends the stacked banknote bundles to the transport path, and banknotes as change Is provided with a withdrawal holding unit 35 for discharging the product to the outside of the apparatus and a control means (CPU) 40 for controlling them.

The deposit taking-in unit 4 is provided with a separating and feeding mechanism for feeding a plurality of bills that have been batch-loaded into the transport path 5 while separating them one by one.
The conveyance mechanism 10 conveys the banknotes fed one by one from the deposit taking-in section 4 by a predetermined route, thereby making the first or second banknote storage unit (reflux type banknote storage device) 20 by denomination. A sorting and feeding function for feeding to 25, a function for sequentially feeding and depositing banknotes fed out one by one from the first or second banknote storage sections 20 and 25 into the temporary storage section 30, and a temporary storage section And a batch conveyance function for collectively feeding the banknote bundle fed from 30 to the second banknote storage unit 25 which also serves as a collection storage unit. By switching and driving each roller, belt, and gate 11 under the control of the control means 40, each of the above transport functions can be realized at a predetermined timing.

The first banknote storage unit 20 is dedicated to the first banknote, for example, a 10,000 yen banknote, and has a reflux function for sending 10,000 yen banknotes once received via the transport path 5 to the transport path 5 one by one. Have.
The second banknote storage unit 25 is a second banknote that is frequently used as change, for example, a thousand-yen banknote, and sends the thousand-yen banknotes once received via the transport path 5 to the transport path 5 one by one. It has a switchback type reflux function.
The temporary storage unit 30 receives the banknotes fed out one by one from the first and second banknote storage units 20 and 25 one by one, and stacks a predetermined allowable number of banknotes, and stacked banknotes It has a batch delivery function for feeding a bundle to the transport path 5 in a batch.
In the present invention, for example, the second banknote storage unit 25 is configured to be detachable (including in / out) in a cassette manner, and is provided on the wall of the exterior body 3 facing the second banknote storage unit 25 (not shown). The second banknote storage unit 25 is taken out by opening the door, and the stored banknotes can be collected.

The feature of the present invention is that the operator operates a predetermined recovery switch in the banknote recovery operation at the end of work, so that the control means 40 transports 10,000 yen banknotes in the first banknote storage unit 20 one by one. 5 and then transported at a high speed by the transport mechanism 10 to deposit a predetermined number of sheets (for example, 15 sheets) on the temporary storage unit 30, and then, the 15-thousand-yen banknote bundle in the temporary storage unit is transferred to the second banknote. By repeating the batch transport operation into the storage unit 25, all 10,000 yen bills stored in the first banknote storage unit 20 are transferred to the second banknote storage unit 25. The number of banknotes sent to the temporary storage unit 30 is counted based on passage information detected by a paper passing sensor disposed at an appropriate position such as a conveyance path.
In this embodiment, the second banknote storage unit 25 is also used as the collected banknote storage unit, and the first and second banknotes are collected in the second banknote storage unit 25 at the end of the operation, thereby collecting them in a lump. The collection work can be performed. Therefore, it is preferable that the second banknote storage unit 25 is configured as a cassette type that can be detached from the apparatus main body or can be taken in and out. Of course, the second banknote storage unit 25 that stores thousand-yen banknotes that are frequently used as banknotes that are used as change as well as banknotes that are thrown in by the user is also used as the banknote collection storage section. By adopting a configuration in which bills with low usage frequency such as yen bills are transferred to the second bill storage unit 25, it is possible to shorten the collection time.

The temporary storage unit 30 has a configuration for stacking banknotes conveyed at high speed one by one in a stacked state, and sending the stacked banknote bundles to the transport path in a lump, and the banknotes sent to the transport path Since the bundle is fed into the second banknote storage unit 25 at once, the collection efficiency can be greatly increased. That is, 10,000 yen banknotes in the first banknote storage unit with a small number of stored sheets are stacked and stored in the temporary storage unit 30 and then transferred to the second banknote storage unit as a bundle of banknotes one by one. It is clear that the recovery time is significantly shortened as compared with the conventional apparatus for recovery. And since the exclusive collection banknote accommodating part is not provided separately, the whole size of an apparatus can be made small.
According to the banknote handling apparatus according to this embodiment, when collecting the banknotes stored in one banknote storage part in the other banknote storage part in the configuration in which the denominated switchback reflux type banknote storage part is provided, Since the batch conveyance with the temporary holding unit interposed is performed, the transfer processing time can be shortened without increasing the size of the apparatus. That is, using a temporary storage unit having a simpler structure than the reflux-type banknote storage unit, the stored banknotes to be transferred are fed to the temporary storage unit one by one and accumulated, and the stacked banknote bundle is directly placed on the same transport path. Since it is fed out and bundled and conveyed to the banknote storage part that also serves as the collected banknote storage part, the time required for the banknote transfer process can be shortened.

Next, FIG. 2 is a perspective view showing a configuration of a switchback reflux-type banknote storage unit (reflux-type banknote storage device) according to an embodiment of the present invention, and FIGS. It is a side view which shows the structure and operation | movement of a banknote accommodating part. Below, the structure of the 2nd banknote accommodating part 25 used also for banknote collection | recovery is demonstrated.
The second banknote storage unit 25 introduces banknotes S into the banknote stacking mechanism 50 and the banknote stacking mechanism 50 one by one or as a banknote bundle, or transports banknotes in the banknote stacking mechanism one by one. And a banknote depositing / dispensing mechanism 70 to be fed out. These are controlled by the control means 40.
The banknote depositing mechanism 50 is supported so as to be able to move up and down between the most advanced feeding position (FIG. 3A) and the lowered receiving position (FIG. 3B), and deposits banknotes on the upper surface in a stacked state. A stacking member 51, an elastic member (not shown) that elastically biases the stacking member 51 upward, and a banknote or banknote bundle introduced from the banknote deposit and withdrawal mechanism 70 by moving up and down above the stacking member 51 A pusher 55 that presses against the upper surface, and a pusher lifting mechanism (not shown) including a motor, a gear, and the like that lift and lower the pusher 55 are provided.

The banknote depositing / dispensing mechanism 70 includes an upper roller (friction roller) 71 and a lower roller (reverse roller) 72 that rotate while being nipped with each other, and supports the upper roller 71 rotatably and moves the lower roller 72 up and down. An upper roller support portion 75 that changes the distance between the pickup roller 78 and a pickup roller 78 that contacts the top surface of the banknotes deposited on the stacking member 51 and feeds them one by one toward the nip portion of both rollers. The distance between the upper roller 71 and the lower roller 72 (separable distance) is regulated by being pivotally supported in a vertically swingable manner by a fixing portion (not shown) and engaging with the upper roller support portion 75. And a restriction arm 80 that also serves as a bill guide for guiding the bill at the time of introduction and feeding, and upper and lower rollers. 1,72, and a roller drive mechanism (not shown) for driving the pickup roller 78 (motor, gear, etc.), and a.
The upper roller 71 is a friction roller in which the frictional resistance of the portion in contact with the banknote surface is increased, and rotates forward and backward by switching the driving force from a motor (not shown). On the other hand, the lower roller 72 is a reverse roller that is always rotationally driven in the bill introduction direction (clockwise direction in FIG. 3), and returns the lower bill to the bill stacking mechanism side when double feeding occurs during bill dispensing. Have a role. When a single banknote or banknote bundle is introduced, the upper roller that rotates in the introduction direction is supported by rotating in the introduction direction.

The upper roller support portion 75 includes a shaft 76 that is fixed through the center of the upper roller 71, a bearing 76a, and a bearing 77. The shaft 76 is supported by a support member (not shown) so as to be movable up and down. Therefore, the upper roller 71 can move up and down between a lowered position in contact with (or close to) the lower roller 72 and a raised position separated from the lower roller 72 by moving up and down.
The upper roller 71 is configured to come into contact with or close to the lower roller 72 by its own weight including the weight of the shaft 76 or by downward biasing by a spring (not shown). Then, the upper roller 71 is pushed up by a thickness corresponding to the difference in thickness of one bill passing through the nip portion at the time of introduction, or a bundle of bills, or one bill passing at the time of payout. It functions to allow the bundle to pass smoothly. When the stopper 81 is in the lowered position shown in FIG. 3A, the movable range of the upper roller 71 is restricted to a width corresponding to one bill, so that only one bill is paid out to the transport path 5. It becomes possible. On the other hand, when the stopper 81 is in the raised position shown in FIG. 3B, the movable range of the upper roller is expanded to a width that allows passage of a predetermined number of banknote bundles (for example, 15 sheets). The upper roller 71 moves up and down according to the thickness of banknotes (bundles) that pass through, so that it becomes possible to introduce both a single banknote and a banknote bundle.

The pick-up roller 78 is supported at the center by a shaft 79 and rotates in the payout direction (clockwise direction in FIG. 3) by a driving force from a motor (not shown), so that The upper banknote is sent out to the nip portion of the upper and lower rollers 71 and 72.
The control means 40 rotates both the upper and lower rollers 71 and 72 in the introduction direction when introducing a single banknote or banknote bundle into the banknote stacking mechanism side, while discharging the upper roller 71 during banknote dispensing. Control is performed such that the lower roller 72 is rotated in the introduction direction and the lower multi-fed banknote is returned to the stacking member 51 side.
The pusher 55 includes two presser pieces 56 that are spaced apart from each other in the width direction so as to be able to press only both edges of the banknote in the width direction, and a connecting piece 57 that connects both presser pieces 56. . When the banknote is introduced as shown in FIG. 3B, the pusher 55 is in contact with the upper surface of the stacking member 51 (the upper surface of the banknote on the stacking member 51) and is pressed down by the presser pieces 56. The banknote or banknote bundle S newly introduced by 72 is once placed on the presser pieces 56. When both presser pieces 56 are raised in this state, the stacking member 51 is raised by an urging member (not shown). The newly introduced banknote is in a state where its central portion is sandwiched between the lower surface of the regulating arm 80 and the upper surface of the stored banknote on the stacking member 51. Since both the presser pieces 56 only support both edges in the width direction of the bill or banknote bundle from the lower side, when both presser pieces 56 are further raised, both end portions in the width direction of the bills are deformed upward and presser. Only the piece rises and the banknote remains on the stacking member. When a subsequent banknote is introduced, the pusher descends again onto the stacking member 51 and presses down the stacking member while holding down the stacked banknote, thereby allowing the subsequent banknote (bundle) to be received.

The restricting arm 80 is configured to be able to swing in the vertical direction by supporting the rotating shaft 82 by a fixing portion (not shown), and the stopper 81 integrated in the front portion is a shaft 76 (bearing) of the upper roller 71. 76a) is arranged so as to overhang. While the restricting arm 80 is pushed up to the ascending position (stopper descending position) shown in FIG. 3A by riding on the pusher by the protruding portions 83 protruding from both edges in the width direction when the pusher 55 is raised, When the pusher 55 is lowered, the pusher retreats downward to shift to the lowered position (stopper raised position) shown in FIG. 3B by its own weight or urging force. As the pusher 55 moves up and down, the stopper arm 81 moves up and down to change the height position of the upper roller with respect to the shaft 76, so that the height position of the upper roller 71 is lowered and raised. It is comprised so that it may restrict | limit to either.
That is, the restricting arm 80 pushes up the protruding portion 83 provided at the rear portion 80a by the pusher 55 in the raised position, thereby lowering the stopper 81 provided at the front portion and separating the upper roller 71 and the lower roller 72 from each other. Is configured to increase the separation distance between the upper roller and the lower roller to the maximum value by raising the stopper 81 by lowering the rear portion when the pusher 55 is lowered. Yes.

  In the above configuration, when banknotes stored in the banknote stacking mechanism 50 are fed out to the transport path 5 one by one, the pusher lifting mechanism (not shown) is operated as shown in FIG. By raising, the stacking member 51 is raised to the feeding position by an elastic member (not shown), and the pusher 55 pushes up the rear part of the restriction arm 80, so that the stopper 81 at the front part of the restriction arm rotates downward and the shaft of the upper roller 71 The vertical movement range of the upper roller 71 is suppressed to the thickness of one banknote (for example, 0.3 mm) in contact with or in proximity to the bearing 76a provided in 76. In this state, the banknote (bundle) S is pressed between the upper surface of the stacking member 51 and the pickup roller 78, and in this state, the pickup roller 78 is driven to rotate in the feeding direction, so that the banknote is bundled. Each sheet can be sent out to the nip portion of the upper and lower rollers 71 and 72. At this time, the upper roller 71 is rotated in the feeding direction (clockwise direction) by the driving force from the motor, while the lower roller 72 is rotated in the return direction (clockwise direction). Even if it is sent out in a state, only the upper banknote can be paid out forward, and the lower banknote can be returned to the stacking member 51 side.

  Next, when the banknote transported from the transport path 5 is introduced into the banknote stacking mechanism 50, the pusher lifting mechanism (not shown) is operated to lower the pusher 55 as shown in FIG. The stacking member 51 is lowered to the receiving position against the elastic member, and the pusher 55 is lowered, whereby the regulating arm 80 swings clockwise around the shaft 82 by its own weight, and the front stopper 81 is raised. And a predetermined distance from a bearing 76a provided on the shaft 76 of the upper roller. For this reason, the range in which the upper roller 71 can be moved up and down is expanded to, for example, the thickness of 15 bills. In this state, when a single banknote or banknote bundle enters the nip portion of the upper and lower rollers 71 and 72 from the conveyance path 5 side, the upper roller 71 is moved in the introduction direction (counterclockwise by the driving force from the motor. The lower roller 72 rotates in the return direction (clockwise direction) while rotating in the vertical direction according to the banknote thickness. It can be introduced while being dropped onto the presser piece 56). The introduced banknote is correctly guided and seated on the banknote stacking member (holding piece 56) while being guided by the lower surface of the regulating arm 80 which also serves as a banknote guide.

  As described above, according to the present invention, in the banknote receiving mode, the interval between the rollers is narrowly regulated so that only one banknote can pass through, while in the mode in which the banknote bundle is also received, the upper roller is It is possible to cope with both modes by relaxing the regulation so that it can move up and down according to the bill thickness. Moreover, since the mode switching using the stopper is linked to the vertical movement of the pusher that holds the banknotes on the banknote stacking member, not only the deposit / withdrawal of a single banknote while achieving downsizing without complicating the configuration. A switchback reflux type banknote storage device capable of batch introduction of banknote bundles can be constructed.
