Japanese Patent No. 5650317 JP 2014-109797 A

  By the way, the inventor of the present application repeats storing and feeding out the banknotes in the storage unit in a state where the storage unit is almost full, regardless of whether the storage unit is a winding storage unit or a stack storage unit. And various problems occur.

  Here, repeated storage and feeding of the banknote in a state where the storage unit is almost full may occur for the following reason. In the banknote pay-in / pay-out device, when there are a plurality of storage units for storing the same type of banknotes, the priority use order is set for the plurality of storage units. In other words, when storing banknotes, the banknotes are stored in the storage unit with the highest priority order, and if the storage unit reaches the full amount, in other words, the banknotes are stored in the storage unit with the highest priority order. If not, the banknote is stored in the storage unit having the next highest priority order. With this configuration, the storage unit having the highest priority order of priority stores the banknotes preferentially, and thus tends to be full. Here, a case is considered in which the storage unit having the highest priority use order is in a full state, and the other storage units do not store any payable bills. If banknotes can be stored in the storage unit with the highest priority order by feeding out banknotes from the storage unit in the full state, the next banknote to be stored is stored in the storage unit with the highest priority order. Will do. The storage part becomes full again. In this state, the banknotes cannot be stored, but if the banknotes can be stored by paying out the banknotes, the banknotes to be stored next will be stored in the storage unit having the highest priority use order. When the priority use order is set in this way, the storage unit having the higher priority use order repeats storing and feeding out the banknotes in the storage unit in a state close to being full.

  The rewind-type storage unit wraps the banknotes around the drum together with the tape drawn from the tape reel.When the rewind-type storage unit is almost full, the outer diameter of the drum around which the tape and the banknotes are wound is large. Has become. Here, the “outer diameter of the drum” means an outer diameter including a portion constituted by a tape and a bill wound around the drum main body. In the following description, the “drum” may include a drum main body, a tape and a bill wound around the drum main body.

  When the drum is rotated in the winding direction in order to store bills in a state where the outer diameter of the drum is large, the tape close to the drum main body (that is, the inner side in the radial direction) is rotated by rotation of the drum main body. Followed and wound in the winding direction. On the other hand, the tape separated from the drum main body (that is, the tape outside in the radial direction) becomes difficult to follow the rotation of the drum main body due to the influence of inertia. This causes a slip between the inner tape and the outer tape.

  Further, when the drum is rotated in the winding direction, the tape is tensioned, so that the tape at the outermost portion of the drum is stably tightened with a certain force. As a result, when the drum having the larger outer diameter is rotated in the winding direction, the inner tape in the radial direction is strongly tightened, while the radial direction between the inner tape and the outermost tape is increased. The intermediate tape is weakened in tightening as the inner tape is wound in the winding direction.

  When the banknote is fed, the drum rotates in the feeding direction, which is opposite to the winding direction, but after the banknote is fed, the drum is rotated in the winding direction to adjust the position of the drum. I will let you. Even when the banknote is paid out, when the drum rotates in the winding direction, the tape on the inner side in the radial direction is strongly tightened.

  For this reason, when the storage and feeding of the banknotes are repeated in a state where the winding type storage unit is almost full, the tape on the inner side in the radial direction is gradually tightened, and accordingly, the tape on the intermediate portion in the radial direction is accordingly increased. , The tightening gradually weakens. As a result, there may be a case where a bill wound around the drum is shifted at a position where the tape is weakened.

  This problem becomes remarkable especially when storing bills having an irregular thickness. A banknote having an irregular thickness is, for example, a banknote (a so-called composite banknote) in which a paper material and a polymer material are combined. In a composite material banknote, there is also a banknote having a concave / convex shape in which a portion of the polymer material is convex on one side of the banknote and concave on the other side. A banknote having a non-uniform thickness becomes difficult to bend along the surface of the drum when wound around the drum, and a gap may be formed between the banknote and the tape. If there is a gap between the banknote wound around the drum and the tape in the radial direction, when the drum is rotated in the winding direction, the tape is removed so that there is no gap between the tape and the banknote inside the radial direction. Is wound up, and the tape is further tightened. In the tape in the radially intermediate portion, the tightening of the tape on the inner side in the radial direction is increased, and the tightening is further reduced. As a result, when storing a composite material banknote, a problem that the banknote wound around the drum is shifted easily occurs. It should be noted that not only composite material banknotes, but also banknotes provided with Braille on a part of the paper surface and banknotes provided with a thread or a hologram for preventing forgery are not uniform in thickness, and similarly to composite material banknotes, have a drum. The wound banknotes are easily shifted.

  On the other hand, in a stack type storage unit, when the storage amount is almost full, a large amount of banknotes are stacked on the stage, and thus the stacked banknotes are not stable. Therefore, when attempting to stack new bills, the quality of storage is reduced. When a bill is fed in the stack type storage unit, the highest bill is fed while compressing the stacked bills in the overlapping direction. If the stack type storage unit is almost full, when the stacked banknotes are compressed downward, the state of the topmost banknote is not stable, and as a result, the feeding quality of the banknotes is reduced (for example, the banknotes are skewed). ).

  In addition, the stack-type storage unit is not limited to the configuration in which the banknotes are stacked in the vertical direction and stored, and similarly in the configuration in which the banknotes are arranged and stored in the horizontal direction, the storage and feeding of the banknotes are repeated in a state close to the full amount. This causes a reduction in the storage quality and the feeding quality.

  Furthermore, when the banknotes having non-uniform thickness are stored in the stack-type storage unit, the stacked banknotes are inclined, so that the stacked banknotes are further unstable. Therefore, the storage quality and the feeding quality of the banknotes are further reduced.

  As described above, it is not limited to the winding type and the stacking type, and it is desired to avoid repeating the storing and feeding of the banknote in a state where the storage unit is almost full.

  In addition, the above-mentioned trouble is not limited to storage and feeding of bills. A similar problem may occur in all paper sheets including securities such as gift certificates and checks that are stored in the storage unit.

  The technology disclosed herein is made in view of such a point, and a purpose thereof is to repeatedly store and feed out sheets in a sheet processing apparatus in a state where the storage unit is almost full. It is to prevent that.

The technology disclosed herein relates to the sheet processing apparatus, the sheet processing apparatus, as well as accommodating the sheets, configured to feed the paper sheet which houses at least a first housing And a storage unit including a second storage unit, and a control unit configured to control storage and unwinding of the paper sheet in the storage unit.

The control unit stores the paper sheets in the storage unit and stores the paper sheets stored in the paper sheet processing apparatus at the time of processing for storing the paper sheets in the paper sheet processing apparatus. At the time of dispensing processing, the paper sheets are paid out from the storage unit,
When the storage amount of any one of the first storage unit and the second storage unit reaches a predetermined first storage amount, the control unit stores the storage amount of the storage unit. but the less than the first amount of storage, until it reaches the second storage amount set in advance, prohibits the retract and of the paper sheet to the storage portion when the processing for accommodating the paper sheet vital Storing the paper sheets in the other storage section during the processing of storing the paper sheets, and storing the paper sheets from the other storage section in the processing of dispensing the paper sheets. Allow any of the payouts .

  According to this configuration, when the storage amount of the storage unit reaches the first storage amount, storage of paper sheets in the storage unit is prohibited. The storage prohibition is continued until the storage amount of the storage unit reaches the second storage amount. That is, until the storage amount of the storage unit reaches the second storage amount, the storage unit only feeds out the paper sheets and does not store the paper sheets.

  Here, the first storage amount may be, for example, the maximum capacity of the storage section (a capacity set as a so-called full capacity) or a capacity near the maximum capacity (a capacity set as a so-called near full capacity). By setting the first storage amount large, the number of sheets that can be stored in the storage unit increases.

  The second storage amount can be appropriately set at a smaller amount than the first storage amount. The second storage amount is preferably set to a relatively small value in order to prevent repeated storage and feeding of paper sheets in a state where the storage unit is almost full. The second storage amount may be zero (so-called empty) or an amount near zero (a capacity set as a so-called near empty). If the second storage amount is set to zero or an amount near zero, the storage unit performs only the feeding until the stored paper sheets are exhausted or almost exhausted, and does not store bills. Therefore, it is possible to reliably prevent the paper sheet from being repeatedly stored and fed in a state where the storage unit is almost full.

  Thus, with the above-described configuration, it is possible to avoid a problem caused by repeatedly storing and feeding out the paper sheets in a state where the storage amount of the storage unit is almost full.

When the storage amount of the storage unit reaches the second storage amount by feeding out the paper sheets from the storage unit in which the storage is prohibited, the control unit permits the storage of the paper sheets in the storage unit. it may be.

The control unit may store the paper sheet in a storage unit having a small storage amount when storage of the paper sheet is permitted in any of the plurality of storage units .

By doing so, the sheets are stored in the plurality of storage units as evenly as possible, so that the storage units are prevented from being full or nearly full.

The control unit may be configured to, when the feeding of the paper sheet is permitted from any of the plurality of storage units, feed the paper sheet from the storage unit having a large storage amount.

Prior Symbol controller, said first housing portion, and, when the storage amount of the one of the storage portion of said second housing portion reaches the first amount of storage, the storage unit, the paper The storage unit may be set to a storage unit dedicated to feeding only the leaves, and the other storage unit may be set to a storage unit dedicated to storage only for storing the paper sheets.

  When the storage amount of any of the storage units reaches the first storage amount, the storage unit is made to be dedicated to feeding, so that the storage unit is close to the first storage amount (in other words, the storage unit is almost full. In this state), repetition of storing and feeding out the paper sheets is prevented. Even if the storage unit is set only for feeding, it is possible to store paper sheets by setting the other storage unit to a storage unit dedicated to storage. Therefore, the paper sheet processing apparatus having this configuration can always store and feed out the paper sheets by using the plurality of storage units. Further, in this configuration, unlike the conventional configuration in which the priority use order is set, a plurality of storage units can be used equally.

  The control unit sets the storage unit to a storage unit dedicated to storage when the storage unit dedicated to feeding reaches the second storage amount, and sets the other storage unit to a storage unit dedicated to feeding. Is also good.

  When the storage unit dedicated to feeding reaches the second storage amount, the storage amount of the storage unit is sufficiently reduced, so that paper sheets can be stored. Therefore, the storage section is switched from the storage section dedicated to feeding to the storage section dedicated to storage. On the other hand, by setting the other storage section as a storage section dedicated to feeding, paper sheets can be fed. The paper sheet processing apparatus having this configuration can always store and feed out the paper sheets.

  The storage unit may be configured as a take-up type in which the paper sheet is wound around a drum together with a tape.

  As described above, the rewind-type storage unit may cause the paper sheets wound around the drum to be displaced if the storage and feeding of the paper sheets are repeated in a state close to the full amount. As described above, it is possible to prevent the paper sheets from being displaced in the storage unit by avoiding repeating the storage and feeding of the paper sheets when the storage unit is almost full.

  The storage section may be configured in a stack type in which the paper sheets are arranged in contact with each other on a paper surface.

  As described above, the stacking type storage unit may reduce storage quality and / or feeding quality if storage and feeding of paper sheets are repeated in a state close to full capacity. By avoiding repeating the storing and feeding of the paper sheet in a state where the copy portion is almost full, the storage quality and / or the feeding quality are prevented from lowering.

The paper sheet processing method disclosed here,
Using at least a first storage unit and a second storage unit configured to store the paper sheets and to feed out the stored paper sheets,
At the time of processing for storing paper sheets in a paper sheet processing apparatus, the paper sheet processing apparatus stores the paper sheets in a storage unit,
At the time of processing to pay out the paper sheets stored in the paper sheet processing apparatus, the paper sheet processing apparatus feeds out the paper sheets from the storage unit,
When the storage amount of any one of the first storage unit and the second storage unit reaches the predetermined first storage amount , the control unit determines that the storage amount of the storage unit is the first storage amount. less than 1 storage amount until it reaches the second storage amount set in advance, the prohibiting vital to retract and of the paper sheet to the storage portion when the processing for accommodating the paper sheet, the paper sheet Both the storage of the paper sheets in the other storage unit at the time of the processing of storing papers and the feeding of the paper sheets from the other storage unit at the time of the processing of paying out the paper sheets. and a step to allow, the.

Retract and the paper sheet to the storage portion, since is prohibited, repeating the storage and feeding of the sheet can be prevented in a state close to the full amount storage unit.

The paper sheet processing method disclosed herein also includes at least a first storage section and a second storage section configured to store the paper sheets and to feed out the stored paper sheets, respectively. Use
When the storage amount of any one of the first storage unit and the second storage unit reaches a predetermined first storage amount, the control unit determines that the storage amount is greater than the first storage amount. Until a small, predetermined second storage amount is reached, the storage unit is set as a feeding-only storage unit that only feeds out the paper sheets, and the other storage unit is set as a storage unit for storing the paper sheets. A process of setting a storage unit dedicated to storage that only performs
When the storage amount of the storage unit reaches the second storage amount by feeding out the paper sheets from the storage unit dedicated to feeding , the control unit permits storage of the paper sheets in the storage unit. And a step.

  As a result, it is possible to prevent the paper sheet from being repeatedly stored and fed in a state where the storage section is almost full.

  In the paper sheet processing method, when the storage amount of the storage unit reaches a predetermined third storage amount, the storage unit may store the storage unit until the storage amount reaches a preset fourth storage amount that is larger than the third storage amount. Prohibiting feeding of the paper sheet from the storage section and permitting the storage of the paper sheet in the storage section, and storing the paper sheet in the storage section, thereby reducing the storage amount of the storage section. A step of allowing the paper sheet to be fed out from the storage section when the storage amount reaches the fourth storage amount.

  As a result, it is possible to prevent the paper sheet from being repeatedly stored and fed in a state where the storage section is almost full.

  The step of storing the paper sheets in the storage unit includes wrapping the paper sheets together with a tape around a drum, and the step of feeding out the paper sheets from the storage unit includes sending the paper sheets together with the tape from the drum. , May be. That is, the storage unit may be a winding storage unit.

  As described above, according to the paper sheet processing apparatus and the paper sheet processing method described above, it is possible to prevent the paper sheet from being repeatedly stored and fed in a state where the storage unit is almost full.

  Hereinafter, the sheet processing apparatus disclosed herein will be described in detail with reference to the drawings. The following description is an example. FIG. 1 shows the appearance of a banknote pay-in / pay-out device 1 as a paper sheet processing apparatus. The banknote pay-in / pay-out device 1 is installed, for example, at a teller counter of a bank.

  The banknote pay-in / pay-out device 1 executes at least a depositing process for storing the banknote inserted into the depositing port 211 in the storage unit 3 and a paying-out process for paying out the banknote stored in the storage unit 3 to the payment port 231. I do. As described later, the storage unit 3 is configured to be able to feed out stored banknotes. This bill receiving / dispensing machine 1 is a so-called circulation-type bill receiving / dispensing machine 1. That is, the banknotes to be paid out at the time of the payment processing include the banknotes stored in the storage unit 3 at the time of the payment processing.

  The banknote pay-in / pay-out device 1 is roughly divided into an upper processing section 11 and a lower safe section 13 as shown in FIGS. In the housing 111 that constitutes the processing unit 11, a deposit unit 21 having a deposit port 211, a dispensing unit 23 having a dispensing port 231, an identification unit 25 for identifying bills, a deposit unit 21, and a dispensing unit 21. A processing unit side transport unit 41 including a loop transport path 411 that interconnects the gold unit 23 and the identification unit 25 is provided. On the other hand, in the housing 131 constituting the safe section 13, the storage section 3 configured to include a plurality of (eight in the illustrated example) winding-type storage modules 31 and the processing section side transport section 41 are provided. A safe section side transport section 43 including a transport path 431 that connects the loop transport path 411 and each storage module 31 to each other is provided. Here, the housing 131 forming the safe unit 13 is different from the housing 111 forming the processing unit 11 so as to protect the storage unit 3 and the like stored therein with a security level higher than a predetermined level. It is a protective housing 131 configured.

  The deposit port 211 of the deposit section 21 is configured to accept a plurality of bills at a time. Although not shown in detail, the depositing unit 21 includes a pay-out mechanism that feeds a plurality of bills inserted into the deposit port 211 one by one to the loop transport path 411. The dispensing port 231 of the dispensing unit 23 is configured to be able to hold a plurality of bills at a time.

  The processing unit-side transport unit 41 transports the banknotes along the loop transport path 411 in the clockwise direction and the counterclockwise direction in FIG. Although not shown, the loop transport path 411 includes a combination of a number of rollers, a plurality of belts, and a plurality of guides. The banknotes are transported shortly along the loop transport path 411 at a predetermined interval.

  The identification unit 25 is provided on the loop transport path 411. The identification unit 25 is configured to identify at least one of the authenticity, the denomination, and the fitness of each banknote conveyed along the loop conveyance path 411.

  The transport path 431 of the safe section-side transport section 32 is connected to the loop transport path 411 via the branching mechanism 419. The branching mechanism 419 operates to selectively convey banknotes conveyed from a predetermined direction in two different directions, respectively, at a collection position of conveyance paths extending in three different directions. The branching mechanism 419 selectively sends the banknotes being conveyed clockwise or counterclockwise on the loop conveyance path 411 to the conveyance path 431 of the safe section side conveyance section 43 to be stored in the storage section 3. Alternatively, the banknotes fed out of the storage section 3 and conveyed along the conveyance path 431 of the safe section side conveyance section 43 are conveyed clockwise on the loop conveyance path 411, or counterclockwise. Switching of whether to convey in the circumferential direction is performed.

Housing portion 3, as described above, the first to take-up of the 8 (in other words, the tape-type) in the illustrated example is configured to include a receiving module 31 _-1 -31 _-8. In the following description, the reference numeral “31” is used to generically refer to each storage module, and the reference numeral “31 ₋ ” is used to distinguish the first, second, third,. ₁ , _31-2 , _31-3 ... ". The number of storage modules 31 is not particularly limited, and may be one or more and an appropriate number may be set. In this example, the eight storage modules 31 are arranged in a row in the depth direction of the apparatus (the left-right direction in FIG. 2) to form one row, and the two rows are stacked vertically. Have been.

  The winding type storage module 31 is not shown in detail because its basic configuration is well known, but in the example shown here, as shown in FIG. A tape reel 311 around which a tape 310 for guiding bills is wound, and a drum 312 for winding bills together with the tape 310 are provided.

  As shown in FIG. 6 and FIG. 11, two tapes are arranged in parallel at intervals in the longitudinal direction of the bill. The tape 310 pulled out from the tape reel 311 reaches the drum 312 after being guided by the tape regulating guide 313.

  The drum 312 is connected to a rotation drive source (not shown). When the rotation drive source is driven, the drum 312 rotates in the bill winding direction (that is, clockwise direction in FIG. 3) and the bill feeding direction (that is, counterclockwise direction in FIG. 3). A torque limiter 314 is attached to the tape reel 311. When the drum 312 rotates in the winding direction in order to wind up the banknote, the tape reel 311 is driven by the drum 312 while the predetermined tension F is applied to the tape 310 by the torque limiter 314 and the tape It rotates in the feeding direction of 310. On the other hand, when the drum 312 rotates in the bill sending direction, the driving force of the rotation drive source of the drum 312 is transmitted to the tape reel 311 by a power transmission mechanism (not shown), and the tape reel 311 takes up the tape 310. Drive rotation in the direction.

  The bill enters the storage module 31 through the entrance 315 connecting the inside and the outside of the storage module 31 and exits from the storage module 31. The take-up storage module 31 stores bills by winding two tapes 310 pulled out from the tape reel 311 around the drum 312 together with the bills that have entered the storage module 31. The banknote is wound around the drum 312 with a predetermined interval therebetween in such a direction that its longitudinal direction is along the rotation center axis of the drum 312 (see also FIG. 6).

  Note that the configuration of the take-up storage module is not limited to the above-described configuration. The number of tapes wound around the drum may be one, or two or more. Further, the tape may be wound around a drum in a state where a bill is sandwiched between two overlapping tapes.

  The transport path 431 of the safe section-side transport section 43 is configured by a combination of a roller, a belt, and a guide, like the loop transport path 411 of the processing section-side transport section 41. The transport path 431 also transports banknotes one sheet at a time. The transport path 431 extends vertically downward from the branching mechanism 419 on the loop transport path 411, and then bends toward the depth side (the left side in FIG. 2) to form two rows of vertically arranged storage paths. The space between the modules 31 extends toward the far side of the banknote pay-in / pay-out device 1. Each storage module 31 is connected to the transport path 431 via the distribution mechanism 432. Each of the sorting mechanisms 432 switches the transport direction of the bills transported along the transport path 431 between a direction along the transport path 431 and a direction toward the storage module 31. The drive of each distribution mechanism 432 is controlled by a control unit 513 described later. Thereby, the bills are sorted and stored in the plurality of storage modules 31 according to the denomination and / or the fitness identified by the identification unit 25.

  FIG. 4 shows a configuration related to operation control of the banknote pay-in / pay-out device 1. The banknote pay-in / pay-out device 1 includes, for example, a control unit 513 based on a known microcomputer. The control unit 513 includes the above-described depositing unit 21, dispensing unit 23, storage unit 3 including the first to eighth storage modules 31, the processing unit side transport unit 41, and the safe unit side transport unit 43. Connected so that transmission and reception are possible. Although not shown, these units 21, 23, 3, 41, and 43 include various sensors having a function of detecting, for example, bills being conveyed along the conveyance path. It is input to the control unit 513. The control unit 513 outputs a control signal based on the input detection signal and the like, and the units 21, 23, 3, 41, and 43 operate according to the control signal.

  The identification unit 25 is also connected to the control unit 513, and the identification unit 25 provides an identification result to the control unit 513. Although illustration is omitted in detail, the operation unit 55 as a human interface part for the operator who uses the banknote pay-in / pay-out device 1 and the banknote pay-in / pay-out device 1 are, for example, a LAN or a serial bus. A communication unit 57 for transmitting and receiving signals to and from a device, and a storage unit 59 for storing various information, such as a general-purpose storage device such as a hard disk drive or a flash memory, are each a bill. It is connected to the depositing / dispensing machine 1.

  The storage unit 59 stores at least the amount of money or the amount of money of the banknotes stored in the banknote pay-in / pay-out device 1. The storage unit 59 also stores the amount of money for each storage module 31.

  The control unit 513 responds to commands from the higher-level terminal received through the communication unit 57 and / or various commands received through the operation unit 55, and controls the units 21, 23, 25, 3, 41, 43, 55, and 57. , 59 are controlled. Accordingly, the banknote pay-in / pay-out device 1 performs various processes including a payment process and a payment process described below.

<Payment processing>
The depositing process is a process of depositing (storing) bills in the bill depositing / dispensing machine 1, and the bills inserted into the depositing port 211 are basically processed according to the identification result by the identifying unit 25 and a preset storage assignment. Is stored in one of the storage modules 31. More specifically, the banknote pay-in / pay-out device 1 operates as follows at the time of payment processing.

  That is, in a state where the bill to be deposited is inserted into the deposit port 211, a deposit processing start command is input to the bill depositing / dispensing machine 1 by operating the upper terminal and / or the operation unit 55, for example. The payout mechanism of the deposit unit 21 pays out the banknotes in the deposit port 211 one by one, and the processing unit side transport unit 41 transports each banknote to the identification unit 25. The identification unit 25 identifies the bill and performs counting. The processing unit side transport unit 41 also passes the banknote normally identified by the identification unit 25 (this banknote is referred to as a normal banknote as a name of a pair of reject banknotes) from the loop transport path 411 through the branching mechanism 419. The sheet is conveyed to the conveyance path 431 of the safe section side conveyance section 43. The safe section-side transport section 43 stores each normal banknote in the predetermined storage module 31 by controlling the sorting mechanism 432 in accordance with the result of identification by the identification section 25 and a preset storage allocation. Each normal banknote is stored in one of the storage modules 31 according to the denomination or the damage.

  On the other hand, the processing unit side transport unit 41 pays out a reject banknote that cannot be accepted by the banknote pay-in / pay-out device 1 as it is, such as a banknote that cannot be authenticated by the identification unit 25, to the cash outlet 231. In addition, at the time of the depositing process, the banknotes that cannot be stored due to the storage module 31 being full (that is, overflow banknotes) are also paid out to the outlet 231. After the payment processing is completed, the money stored in the storage unit 59 is updated.

<Withdrawal processing>
The dispensing process is a process of paying out bills stored in the bill receiving / dispensing machine 1. Specifically, the dispensing process is started by performing at least a predetermined dispensing operation for designating the denomination and the number of sheets at the upper terminal and / or the operation unit 55. The storage unit 3 feeds out a specified number of banknotes of the specified denomination from the storage module 31 by the specified number. The safe section-side transport section 43 transports the fed banknotes to the loop transport path 411 of the processing section-side transport section 41 via the transport path 431. The processing unit side transport unit 41 transports each bill to the identification unit 25, and after the identification unit 25 performs identification, each bill is paid out to the outlet 231. After the end of the withdrawal processing, the money stored in the storage unit 59 is updated.

(Explanation of bills to be handled by banknote pay-in / pay-out machine)
Next, a bill to be handled by the bill depositing / dispensing machine 1 will be described. In recent years, a so-called composite material banknote combining a paper material and a polymer material has been issued. The composite material banknote has a part of the banknote, for example, in the example of the 20 euro banknote shown in FIG. 5, has irregularities formed by a polymer material at a position on one side of the center in the longitudinal direction of the banknote. The irregularities are concave on one surface (the front surface in FIG. 5) of the bill and convex on the other surface (the back surface in FIG. 5). The composite material banknote has an asymmetric shape in the longitudinal direction due to the unevenness.

  The front and back and the direction of the bills inserted into the deposit port 211 are not uniform. Therefore, the directions of the bills transported along the loop transport path 411 and the transport path 431 are divided into four directions from the A direction to the D direction, as shown in FIG. That is, the A direction is a direction in which the bill is a front and the direction follows the transport direction (as indicated by the arrow in FIG. 5, the direction from the bottom to the top of the paper). The B direction is a direction in which the bill is front and the direction is opposite to the transport direction. The C direction is a direction in which the bill is on the back and the direction is opposite to the transport direction. The D direction is a direction in which the bill is on the back and the direction follows the transport direction.

  As described above, the banknote pay-in / pay-out device 1 is configured to convey banknotes in a short direction. As shown in FIG. 6, the storage module 31 winds the banknote BN around the drum 312 with the longitudinal direction of the banknote BN along the center axis of the drum 312. Therefore, when the banknote is in the A direction and the B direction among the four directions described above, the projections of the irregularities face inward in the radial direction of the drum 312 and are on the contraction side in the bending of the banknote. It is difficult to bend along the surface. In this case, a gap may be formed between the tape 310 and the banknote BN, particularly in the uneven portion, even when the banknote BN is tightened with the tape 310.

  On the other hand, when the banknotes are in the C direction and the D direction, the convexities of the concavities and convexities face outward in the radial direction of the drum 312 and are on the extension side in the bending of the banknotes. Therefore, the banknotes are relatively easily bent along the surface of the drum 312. .

  Further, the thickness of the banknote having irregularities is not constant. Therefore, when bills having irregularities overlap in the radial direction of the drum 312, the bill may be inclined.

  When the above-described difficulty in bending due to the direction of the bill and the unevenness of the thickness due to the unevenness are combined, for example, the tape 310 and the bill BN wound around the drum 312 become circular as illustrated in an exaggerated manner in FIG. Instead of a columnar shape, the drum 312 may have a truncated cone shape in which the diameter on one side in the central axis direction is large and the diameter on the other side is relatively small.

  The banknotes to be handled by the banknote pay-in / pay-out device 1 are not limited to composite material banknotes, but are banknotes of conventional paper materials, that is, the banknotes have a constant thickness and extend along the surface of the drum 312 regardless of the direction of the banknotes. It also includes banknotes that are easy to bend.

  In addition, for example, a banknote in which a braille portion is provided in a part of a banknote or a banknote in which a thread or a hologram for preventing forgery is provided in a part of the banknote is also a banknote to be handled by the banknote depositing / dispensing machine 1. It is possible. A bill provided with Braille, thread, or hologram is not necessarily constant in thickness, and the bendability along the surface of the drum 312 may vary depending on the direction of the bill. Therefore, as shown in FIG. 6, the tape 310 and the banknote BN wound around the drum 312 may be shaped like a truncated cone.

(Problem that can occur in the retractable storage unit)
As described above, in the retractable storage module 31, the bill is wound around the drum 312 together with the tape 310. When the storage amount of the banknotes in the storage module 31 increases, the outer diameter of the drum 312 increases due to the tape 310 and the banknotes wound around the drum 312. When the drum 312 is rotated in the winding direction in order to store bills in a state where the outer diameter of the drum 312 is large, as shown conceptually in FIG. It is wound in the winding direction following the rotation of the drum 312. Thus, the tape 310 at a position near the drum 312 is strongly tightened. On the other hand, the tape 310 at a position distant from the drum 312 does not easily follow the rotation of the drum 312 due to inertia. For this reason, slippage occurs between the inner tape 310 and the outer tape 310.

  When the drum 312 rotates in the winding direction, a predetermined tension F is applied to the tape 310 at the outermost diameter of the drum 312 by the torque limiter 314 of the tape reel 311 as described above. Therefore, the fastening state of the tape 310 at the outermost diameter portion of the drum 312 is stable.

  Therefore, when the drum 312 rotates in the winding direction in a state in which the storage module 31 has a large storage amount, a difference occurs in the tightening force of the tape 310 depending on the radial inner and outer positions of the drum 312. In particular, the tightening of the tape 310 at the radially intermediate portion between the inner tape 310 and the outermost tape 310 becomes weaker as the inner tape is wound in the winding direction. When the tightening of the tape 310 is weakened, a gap is formed between the tape 310 and the bill, and the bill wound around the drum 312 is easily shifted in the rotation axis direction of the drum 312.

  When the banknotes are fed from the winding type storage module 31, the drum 312 is rotated in the opposite direction to the winding direction. However, after the banknotes have been fed, the position of the drum 312 is adjusted. Is slightly rotated in the winding direction. For this reason, when the banknotes are fed, similarly to the case of storing the banknotes, the tightening of the tape 310 inside the drum 312 becomes strong, and the tightening of the tape 310 may become weak in the intermediate portion.

  Here, the banknote pay-in / pay-out device of the conventional configuration is used to store banknotes of the same type in a plurality of storage modules (for example, when a genuine note of the same denomination can be stored in any of the two storage modules). Set prioritized use order for a plurality of storage modules.

  This conventional configuration will be described in detail with reference to FIG. FIG. 8 shows two storage modules 31L and 31R on the right and left sides. The right and left storage modules 31L and 31R shown in FIG. 8 do not mean adjacent storage modules in the banknote pay-in / pay-out device, but mean two storage modules that store banknotes of the same type. It is assumed that the left storage module 31L has a relatively high priority use order, and the right storage module 31R has a relatively low priority use order.

  In the initial state P81 of the banknote pay-in / pay-out device, the two storage modules 31L and 31R are both empty. When the banknotes are stored in the initial state P81, the banknotes are stored in the left storage module 31L having a higher priority use order. In addition, the bill is paid out from the left storage module 31L that stores the bill (see the arrow in FIG. 8).

When the storage amount of the left storage module 31L increases and banknotes can no longer be stored in the left storage module 31L (exactly, the left storage module 31L has a preset full capacity, or When the near full capacity is reached near the full capacity), the banknotes are stored in the right storage module 31R having the lower priority use order, as shown at P82 in FIG. The preset full capacity is the maximum value of the storage amount stored in the storage module 31L, and may be defined by the number of bills, or may be defined by the maximum diameter of the drum on which the bill is wound. Yes, and may be defined by the weight of the stored bills. When the maximum value of the storage amount is set based on the number of banknotes, the maximum diameter of the drum changes due to the effect of the difference in thickness between the new and old bills of the stored banknotes. The full capacity may be hereinafter referred to as a full capacity.

  When dispensing bills, the bills are dispensed from the left storage module 31L having a higher priority use order. As a result of the bill being fed from the left storage module 31L, the left storage module 31L is again in a state capable of storing bills. When the left storage module 31L is in a state in which bills can be stored, bills are stored in the left storage module 31L having a higher priority use order, and bills are fed out from the left storage module 31L. (See page 83).

  FIG. 10 is a diagram illustrating a change in the storage amount of the storage module. In the conventional configuration in which the priority use order is set for a plurality of storage modules, as shown by the broken line in FIG. 10, the storage module having a higher priority use order repeats the storage and feeding out of the banknote in a state close to the full amount. Become.

  As described above, when the banknotes are stored or the banknotes are fed in a state where the storage module 31 has a large storage amount, the tightening of the tape 310 is weakened at the radially intermediate portion of the drum 312. Therefore, in the conventional configuration, the tightening of the tape 310 is further weakened at the radially intermediate portion of the drum 312.

  In particular, in the case where the banknotes stored in the storage module 31 include a composite material banknote, if there is a gap between the tape 310 and the banknote due to the difficulty in bending the composite material banknote, the On the inner side in the radial direction, this is equivalent to the remaining portion of the fastening of the tape 310 remaining. Therefore, when the drum 312 is rotated in the winding direction, the winding amount of the inner tape 310 is further increased, while the tape 310 is tightened more in the radially intermediate portion of the drum 312. It becomes weaker, the gap between the tape 310 and the bill becomes further larger, and the bill wound around the drum 312 is likely to shift.

  The banknote pay-in / pay-out device 1 is configured to solve this problem by adopting various configurations of Configuration 1 to Configuration 4 described below. Note that the banknote pay-in / pay-out device 1 may employ all of Configurations 1 to 4 described below, or one or more of them may be appropriately selected and employed.

(Configuration 1: A configuration for preventing the storage module from being repeatedly stored and fed out in a state where the storage module is almost full)
As described above, repeated storage and delivery of bills in a state in which the take-up type storage module 31 is almost full causes the bills to shift. Therefore, the banknote pay-in / pay-out device 1 is configured to prevent the storage module 31 from repeatedly storing and feeding out banknotes in a state where the storage module 31 is almost full.

  Specifically, in the banknote pay-in / pay-out device 1, the priority use order of the storage modules 31 is not set. When the storage amount of the storage module 31 is within a preset range, the control unit 513 of the banknote pay-in / pay-out device 1 selects one of storing the banknote in the storage module 31 and feeding out the banknote from the storage module 31. One is forbidden and the other is allowed. More specifically, when the control unit 513 reaches the preset first storage amount, the control unit 513 prohibits the storage of the bill in the storage module 31 until the preset second storage amount is reached, and dispenses the bill. Only allow.

  Here, the first storage amount is set based on the maximum capacity of the storage module 31 (that is, full capacity) or an amount near the maximum capacity (that is, near full capacity). The first storage amount may be a full capacity or a near full capacity.

  The second storage amount is smaller than the first storage amount and is appropriately set. In order to prevent the storage module 31 from repeatedly storing and feeding banknotes in a state where the storage module 31 is almost full, it is preferable that the second storage amount is largely apart from the first storage amount. The second storage amount may be zero (that is, empty) or an amount near zero (that is, near empty).

  Next, an example of a change in the storage amount of the plurality of storage modules 31L and 31R in this configuration will be described with reference to FIG.

  P91 in the initial state is the same as P81 in FIG. When storing banknotes in the initial state P91, the banknotes can be stored in both the left and right storage modules 31L and 31R. In the illustrated example, bills are stored in the left storage module 31L. When the bill is paid out, the bill is paid out from the left storage module 31L storing the bill (see the arrow in FIG. 9).

The storage amount of the left storage module 31L is increased, and the left storage module 31L is increased.
When reaches the first storage amount, the control unit 513 prohibits the storage of the bill in the left storage module 31L as described above. The control unit 513 permits the dispensing of bills from the left storage module 31L. At this time, the control unit 513 permits the banknote to be stored in the right storage module 31R (see P92 in FIG. 9).

  When the bill is fed from the left storage module 31L, even if the storage amount of the left storage module 31L is less than the first storage amount, the control unit 513 controls the bill until the storage amount reaches the second predetermined amount. Prohibition of storage. Therefore, the storage module 31L on the left becomes a storage module exclusively for feeding out until the storage amount reaches the second predetermined amount. During this time, the bill is stored in the right storage module 31R. The control unit 513 prohibits the bill from being fed from the right storage module 31R, and sets the right storage module 31R as a storage module dedicated to storage.

  When the storage amount of the left storage module 31L reaches the second storage amount by the bill being fed from the left storage module 31L, the control unit 513 sets the left storage module 31L to a storage module dedicated to storage, and It is allowed to store bills in the storage module 31L. On the other hand, the control unit 513 sets the right storage module 31R as a storage module dedicated to feeding, and prohibits storing bills in the right storage module 31R. That is, when the storage amount of the left storage module 31L reaches the second storage amount, the storage module dedicated to storage is replaced with the storage module dedicated to feeding (see P93 in FIG. 9).

  As illustrated by the solid line in FIG. 10, when the storage amount reaches the first storage amount, the left storage module 31L becomes a storage module dedicated to withdrawal, and stores banknotes until the storage amount reaches the second storage amount. It is forbidden. The storage module 31L on the left side is prevented from repeatedly storing and feeding banknotes in a state close to being full.

  Further, as illustrated by a dashed line in FIG. 10, the right storage module 31R becomes a storage module only for storage if the left storage module 31L is a storage module exclusively for feeding, and the left storage module 31L is a storage module for left storage. Is a storage module dedicated to feeding. Accordingly, the storage module 31R on the right side is also prevented from repeatedly storing and feeding out banknotes in a state close to being full.

  As a result, it is possible to prevent the bill wound around the drum 312 from being displaced in the storage module 31 due to weakening of the tape 310.

  Further, in this configuration, since one of the plurality of storage modules 31 is set to the storage module 31 dedicated to storage and the other is set to the storage module 31 dedicated to feeding, the storage and feeding of the banknotes can be always performed. . Further, unlike the conventional configuration in which the priority use order is set, the plurality of storage modules 31 can be used equally.

  In the above description, when the storage amount of the left storage module 31L set to be exclusively used for feeding reaches the second storage amount, the left storage module 31L is set to the storage module dedicated to storage, and the right storage module 31R is set to dedicated storage. Is set to the storage module. On the other hand, when the storage amount of the right storage module 31R set only for storage reaches the first storage amount before the storage amount of the left storage module 31L reaches the second storage amount, the timing is determined. Thus, the storage module 31R on the right side may be set as a storage module dedicated to feeding, and the storage module 31L on the left side may be set as a storage module dedicated to storage.

  Further, the left storage module 31L prohibits one of storage and feeding of the banknote between the first storage amount and the second storage amount, whereas the right storage module 31R performs the third storage amount and the fourth storage amount. Between the storage amounts, one of storing and feeding out the banknote may be prohibited.

  Further, in the above configuration, when the storage amount is between the first storage amount and the second storage amount, one storage module 31 is dedicated to storage and the other storage module 31 is dedicated to feeding. Differently from this, each of the plurality of storage modules 31 is configured to permit both storage and feeding of banknotes, and when the storage amount of any one of the storage modules 31 reaches the first storage amount, Regarding the storage module 31, while the storage of banknotes is prohibited up to the second storage amount and the dispensing of banknotes is permitted, the other storage module may permit both storing and dispensing of banknotes. Good.

  That is, as described above, the problem of the banknote misalignment occurs when the storage module 31 repeats storing and feeding out banknotes in a state where the storage module 31 is almost full. Even if the payout is repeated, the bill is unlikely to shift. Therefore, without setting one storage module 31 exclusively for storage and setting the other storage module 31 exclusively for feeding, and in a state where the storage amount of the storage module 31 is relatively small, the storage of the banknotes for the plurality of storage modules 31 is performed. Extension may be permitted.

  In this case, when storing the banknotes, the banknotes are stored in the storage module 31 having a small storage amount among the plurality of storage modules 31, and when the banknotes are to be paid out, the storage amount is large among the plurality of storage modules 31. Banknotes may be fed from the storage module 31. This makes it possible to store bills in the plurality of storage modules 31 as evenly as possible.

  Then, in the configuration in which the storing and feeding out of the banknotes are permitted for each of the plurality of storage modules 31, when the storage amount of any of the storage modules 31 reaches the first storage amount, the storage module 31 is switched to the second storage module. By prohibiting the storage of the banknotes and permitting the feeding of the banknotes up to the storage amount, it is possible to prevent the storage module 31 from repeatedly storing and feeding the banknotes in a state near the full amount.

(Configuration 2: A configuration for adjusting the starting current of the drum)
As described above, in the retractable storage module 31, the drum 312 is connected to the rotary drive source. When the drum 312 is rotated in the winding direction by the driving force of the rotary drive source, the bill is wound around the drum 312 together with the tape 310. In a state where the diameter of the drum 312 is large (that is, in a state where the storage module 31 has a large storage amount), when the drum 312 starts to rotate vigorously at the start of winding of the banknote and the tape 310, a diameter close to the drum 312 is obtained. The tightening of the tape 310 inside the direction becomes strong. On the other hand, if the rotation start of the drum 312 is moderated at the start of winding, it is possible to suppress the tightening of the tape 310 on the inner side in the radial direction. As a result, it is possible to prevent the tightening of the tape 310 at the radially intermediate portion of the drum 312 from being weakened, and to prevent the bill from shifting.

  Therefore, the control unit 513 changes the starting current at the start of the rotation of the drum 312 according to the storage amount of the storage module 31. Specifically, when the storage amount of the storage module 31 is smaller than a predetermined amount (that is, when the diameter of the drum 312 is relatively small), the starting current is set to the first current value. The first current value is a relatively high current value, and the drum 312 starts to rotate vigorously. However, the diameter of the drum 312 is small, and the tape 310 wound around the drum 312 follows the rotation of the drum 312. It is avoided that the tightening of the tape 310 inside is increased. Therefore, the tightening of the tape 310 is prevented from being weakened at the radially intermediate portion of the drum 312.

  When the storage amount of storage module 31 is equal to or larger than the predetermined amount (that is, when the diameter of drum 312 is relatively large), control unit 513 sets the starting current to the second current value. The second current value is a current value lower than the first current value. As a result, the drum 312 starts rotating slowly. As a result, even when the diameter of the drum 312 is relatively large, the tightening of the tape 310 on the radially inner side of the drum 312 is prevented from being increased, and the tightening of the tape 310 is weakened at the radially intermediate portion. Is prevented.

  Note that when the storage amount of the storage module 31 is equal to or more than the predetermined amount, the control unit 513 may decrease the starting current from the second current value as the storage amount increases. For example, the starting current may be reduced by 0.1 A each time the storage amount (storage number) increases by ten. This makes it possible to optimize the starting current according to the diameter of the drum 312, and to more reliably prevent the tightening of the tape 310 inside the drum 312 in the radial direction from increasing. It becomes possible.

(Configuration 3: Configuration for switching the operation mode of the storage module)
When the drum 312 is rotated in the winding direction, the tightening of the tape 310 inside the drum 312 in the radial direction becomes strong because the tightening of the tape 310 wound around the drum 312 is originally weak. One.

  As described above, even when a composite material banknote is difficult to bend along the surface of the drum 312, when the tape 310 is sufficiently wound and the tension of the tape 310 is sufficiently high, the composite material banknote is applied to the surface of the drum 312. It is possible to wind the bill around the drum 312 by bending it sufficiently along. As a result, there is no gap between the tape 310 and the bill, and the tightening of the tape 310 wound around the drum 312 is sufficiently high. This prevents the tightening of the tape 310 from becoming relatively strong.

  As described above, when the bill is wound around the drum 312, the tape reel 311 rotates following the rotation of the drum 312, so that the tension F of the tape 310 is attached to the tape reel 311 as shown in FIG. F = T / R from the limit torque T of the torque limiter 314 and the diameter R of the tape reel 311. When the diameter of the tape reel 311 is large (that is, when the tape 310 starts to be wound around the drum 312), the tension F of the tape 310 becomes relatively small. become weak.

  In order to increase the tension F of the tape 310, it is conceivable to increase the limit torque T of the torque limiter 314. However, the torque limiter 314 having a large limit torque T is generally expensive. In the banknote pay-in / pay-out device 1 provided with the plurality of storage modules 31, if the expensive torque limiters 314 are employed for all the storage modules 31, the cost is greatly increased.

  Since the shift of bills is particularly remarkable in the storage module 31 that stores composite material bills, it is conceivable to employ the expensive torque limiter 314 only for some of the storage modules 31 that store composite material bills. However, if such a countermeasure is adopted, one banknote pay-in / pay-out device 1 includes two types of storage modules 31. This is not preferable in terms of manufacturing management and maintenance management. Further, the storage module 31 capable of storing the composite material banknotes is limited to a specific storage module 31, which is not preferable in terms of the usability of the banknote pay-in / pay-out device 1.

  Even if the limit torque T of the torque limiter 314 is increased, when a new banknote having a structure that is more difficult to bend appears in the future, a higher limit torque T may be required.

  The configuration disclosed herein increases the tension of the tape 310 without increasing the limit torque T of the torque limiter 314. As described above, the tension F of the tape 310 is determined by F = T / R. As the diameter R of the tape reel 311 decreases, the tension F of the tape 310 increases. Therefore, if only the tape 310 is wound around the drum 312 in advance, and the diameter of the tape reel 311 is made smaller than the initial state indicated by the dashed line in FIG. 3, the tension F of the tape 310 is increased. It is possible to start winding the bill around the drum 312.

  On the other hand, if only the tape 310 is wound around the drum 312 in advance, the maximum capacity of the storage module 31 is reduced accordingly.

  Therefore, the banknote pay-in / pay-out device 1 sets two modes as operation modes of the storage module 31, and switches between the two operation modes for each storage module 31.

  One of the two operation modes is the first mode for increasing the tension of the tape 310 as described above. In the first mode, only the tape 310 is wound around the drum 312 in advance. In the first mode, the maximum capacity of the storage module 31 decreases.

  On the other hand, the second mode is a mode in which only the tape 310 is not wound around the drum 312. In the second mode, the maximum capacity is relatively large while the tension of the tape 310 does not increase.

  As shown in FIG. 11, light-shielding seals 3111 and 3112 for switching between a first mode and a second mode are attached to a tape 310 made of a light-transmitting material. The light-shielding stickers 3111 and 3112 attached to the tape 310 are for detecting the position of the tape 310 pulled out from the tape reel 311, and are disposed on the tape drawing-out path between the tape reel 311 and the drum 312. The light is detected by a light-transmitting tape detection sensor (not shown). The light shield includes a first light shield 3111 for detecting the tape position in the first mode, and a second light shield 3112 for detecting the tape position in the second mode. The first light-shielding seal 3111 is attached to a position closer to the tape reel 311 than the second light-shielding seal 3112.

  When operating the storage module 31 in the second mode, the control unit 513 pulls out the tape 310 until the two second light-shielding stickers 3112 arranged in the longitudinal direction of the tape are detected. Accordingly, the amount of the tape 310 pulled out from the tape reel 311 is relatively reduced, and the diameter R of the tape reel 311 is increased accordingly.

  On the other hand, when operating the storage module 31 in the first mode, the control unit 513 detects the second light-blocking seal 3112 and then pulls out the tape 310 until the first light-blocking seal 3111 is detected. Thereby, the amount of the tape 310 pulled out from the tape reel 311 is relatively increased, and the diameter R of the tape reel 311 is reduced accordingly.

  The banknote pay-in / pay-out device 1 sets whether each of the first to eighth storage modules 31 is operated in the first mode or the second mode by operating the operation unit 55 by the operator. Can be configured. For example, the storage module 31 that stores composite material banknotes may operate in the first mode, and the storage module 31 that does not store composite material banknotes may operate in the second mode. In this way, in the storage module 31 that stores composite material banknotes, in which banknotes are likely to be displaced, the tension F of the tape 310 when winding the banknotes around the drum 312 increases. It becomes possible to wind around. As a result, when the drum 312 is rotated in the winding direction, the tightening of the tape 310 on the inner side in the radial direction is strengthened, and the tightening of the tape 310 in the intermediate portion is relatively weakened, thereby causing a slip of the bill. Can be prevented. On the other hand, in the storage module 31 that does not store the composite material banknotes, since the banknotes are unlikely to shift from the beginning, it is not necessary to increase the tension of the tape 310. Therefore, by operating the storage module 31 in the second mode, it is possible to stably store banknotes and to prevent the maximum capacity of the storage module 31 from being reduced.

  As described above, the banknote pay-in / pay-out device 1 is configured so that the operator sets whether to operate the first to eighth storage modules 31 in the first mode or the second mode. Alternatively, if the banknotes to be stored in the first to eighth storage modules 31 are determined, the storage module 31 that stores the composite material banknotes is automatically operated in the first mode, and the storage that does not store the composite material banknotes is performed. The module 31 may be operated in the second mode.

  Increasing the tension of the tape 310 is also advantageous in preventing the tape 310 from breaking. In other words, the tape 310 pulled out from the tape reel 311 reaches the drum 312 through the tape regulating guide 313 as shown in FIG. 3, but if the tension of the tape 310 is high, flapping in the middle of the tape 310 is suppressed. You. When the tape 310 flaps, the tape 310 may interfere with the tape regulation guide 313 and break the tape 310. However, by increasing the tension of the tape 310 and suppressing the flapping of the tape 310, It is possible to prevent the tape 310 from being cut. Further, increasing the tension F of the tape 310 can prevent the tape 310 from being excessively tightened due to the rotation of the drum 312 in the winding direction, and is also effective in preventing the tape 310 from being damaged. .

(Configuration 4: Control configuration for restricting storage of composite material bills in storage module)
As described above, the displacement of the banknotes in the storage module 31 is caused by the rotation of the drum 312 in the winding direction in a state where the outer diameter of the drum 312 is large. Therefore, the tightening of the tape 310 may be weakened at the radially intermediate portion. Therefore, when the number of composite material banknotes stored in the storage module 31 increases, it is conceivable to prevent the outer diameter of the drum 312 from increasing by reducing the maximum capacity of the storage module 31.

  However, this configuration is not a preferable measure because the storage amount of the storage module 31 is reduced, and the performance (specifications) of the banknote pay-in / pay-out device 1 is reduced. Banknotes that cannot be stored in the storage module 31 are paid out to the outlet 231 as rejected banknotes. Therefore, when the maximum capacity of the storage module 31 decreases, rejected banknotes increase. This makes the banknote pay-in / pay-out device 1 inconvenient.

  Here, as shown in FIG. 5, the difficulty of bending the surface of the drum 312 changes depending on the front and back and the direction of the composite material banknote stored in the storage module 31. This is also a cause of the slippage of the banknotes due to the weakening of the tape 310, but the inventors of the present application have studied and found that the shift of the banknotes is simply the number of stored composite material banknotes, It has been found that not only the front and back and the orientation of the material bill, but also various other factors are combined.

  The configuration 4 disclosed herein does not store only a composite material banknote that is highly likely to cause a true banknote shift in the storage module 31 while considering a combination of various factors. The storage in the storage module 31 prevents the storage amount of the storage module 31 from being reduced. Hereinafter, various factors that cause the bill to be displaced will be described in order, and then the control performed by the bill depositing / dispensing machine 1 for restricting the storage of the composite material bill in the storage module 31 will be described.

<Radial position of composite bill on drum around which bill is wound>
As shown in FIG. 6, when the composite material banknote is wound around the drum 312, the tape 310 and the banknote wound around the drum 312 may have a truncated cone shape. Here, even if the number of composite material banknotes wound around the drum 312 is the same and the tape 310 and the banknotes wound around the drum 312 are also frustoconical, the banknotes are likely to be misaligned. The inventor of the present application has noticed that there are cases where this is difficult to occur.

  That is, the left diagram of FIG. 12 illustrates a case where the composite material banknote is wound around the drum 312 radially in a large amount, and the non-composite material banknote is wound around the radial direction outside. doing. In this state, the bill wound around the drum 312 is inclined as a whole, so that if the tape 310 is loosely tightened, the bill is likely to be displaced. On the other hand, in the right diagram of FIG. 12, a large number of normal bills that are not composite material bills are wound around the inside of the drum 312 in the radial direction, and many composite material bills are wound around the outside of the drum 312 in the radial direction. Is shown. In this state, although the outer peripheral surface of the drum 312 is inclined and the tape 310 and the bill wound around the drum 312 have a truncated cone shape, the bill is not inclined at the radially intermediate portion. Therefore, even if the tightening of the tape 310 is weakened in the middle part of the drum 312, the bill is not easily shifted. As described above, not only the number of composite material bills wound around the drum 312 but also the number thereof is small, and also the radial position of the composite material bill wound around the drum 312 affects the occurrence of the displacement of the bills.

  Therefore, rather than limiting the maximum capacity of the storage module 31 based on only the number of composite material banknotes stored in the storage module 31, when the composite material banknote is located inside in the radial direction, the composite material banknote Is not stored in the storage module 31, it is possible to increase the maximum capacity of the storage module 31 while suppressing the occurrence of a bill shift.

<Relative position between unevenness of composite material banknote and tape>
As shown in FIG. 5, the difficulty in bending the surface of the drum 312 changes depending on the front and back and the orientation of the composite material banknote. When the composite material banknote is in the A direction and the B direction, it is difficult to bend along the surface of the drum 312, so that a gap between the composite material banknote and the tape 310 is generally easily generated when the composite material banknote is wound around the drum 312. However, depending on the relative position between the unevenness of the composite material banknote and the tape 310, the composite material banknote can be sufficiently bent along the surface of the drum 312, and a gap is formed between the composite material banknote and the tape 310. The inventor of the present application has noticed that it is unlikely to occur. In other words, when the distance between the unevenness of the composite material banknote and the tape 310 is short, the unevenness is hard to bend, but the banknote can be pressed down by the tension of the tape 310, and the gap between the composite material banknote and the tape 310 can be reduced. Is less likely to occur.

  FIG. 13 illustrates the relative position between the unevenness of the composite material banknote and the tape 310. In the banknote pay-in / pay-out device 1, in order to allow a difference in size depending on a currency or a denomination, the position of the banknote is shifted (that is, centered, left-aligned, and right-aligned) in a direction orthogonal to the transport direction. It is configured as follows.

  Even if the composite material banknote is conveyed in the same direction A, if it is centered or left-justified, the distance between the unevenness of the composite material banknote and the tape 310 is short. The gap between the tape and the tape 310 is hardly generated. Therefore, even if the composite material banknote is stored in the storage module 31, the banknote is unlikely to be displaced. On the other hand, when the composite material banknote being transported in the A direction is right-aligned, the distance between the unevenness of the composite material banknote and the tape 310 is long, so that the composite material banknote is difficult to bend, and the composite material banknote and the tape 310 A gap is likely to occur between them. Therefore, when the composite material banknote is stored in the storage module 31, the banknote may be shifted. Similarly, even when the composite material banknotes conveyed in the B direction are left-aligned, the distance between the unevenness of the composite material banknote and the tape 310 is long, so that the composite material banknote is difficult to bend, and the composite material banknote is difficult to bend. A gap is easily generated between the tape 310 and the tape 310. Also in this case, if the bills are stored in the storage module 31, the bills may be shifted.

  Here, when the composite material banknote is simply in the A direction or in the B direction, if the banknote is prohibited from being stored in the storage module 31, many banknotes will not be stored in the storage module 31. . The number of rejected banknotes increases, and the usability of the banknote pay-in / pay-out device 1 deteriorates. As described above, the banknotes are prohibited from being stored in the storage module 31 only when the composite material banknote is in the direction A and rightward, and only when the composite material banknote is in the direction B and leftward. For example, it is possible to prevent the number of rejected banknotes from increasing and to prevent the tape 310 and the banknotes wound around the drum 312 from becoming truncated cones as shown in FIG. As a result, it is possible to effectively prevent the bills from shifting, and it is possible to avoid the usability of the bill depositing / dispensing machine 1 from being deteriorated.

<Storage control based on a combination of various factors>
The control unit 513 of the banknote pay-in / pay-out device 1 determines whether or not the composite material banknotes can be stored in the storage module 31 based on a combination of the various factors described above. By doing so, it is possible to store as many composite material banknotes as possible in the storage module 31 and prevent the banknotes wound around the drum 312 from shifting. Specifically, the control unit 513 determines whether or not the composite material banknote can be stored based on the combination shown in FIG. When the storage number of the storage module 31 is equal to or less than a predetermined number (for example, 100) and the composite material banknote in the A direction is right-aligned, and the storage number of the storage module 31 is equal to or less than the predetermined number, and When the composite material banknote is left-aligned, the composite material banknote is not stored in the storage module 31. The composite material bill is paid out to the dispensing port 213 as a reject bill.

  When the storage amount of the storage module 31 is small, when wound around the drum 312, the composite material banknote is positioned inside the drum 312 in the radial direction (see the left diagram in FIG. 12). Also, when the composite material banknote in the A direction is right-aligned or when the composite material banknote in the B direction is left-aligned, the unevenness of the composite material banknote is unlikely to bend, and a gap is easily generated between the tape 310 and the banknote ( See FIG. 13). Therefore, storage of the composite material banknote is prohibited only when these plural factors are combined.

  By doing so, the tape 310 and the bill wound around the drum 312 in the storage module 31 are prevented from forming a truncated cone shape while reducing the number of bills paid out to the outlet 213 as reject bills, and Can be prevented from occurring.

  Note that the composite material bills paid out as rejected bills due to the above-described factors may be stored in the storage module 31 by adjusting the direction, the direction, and the position when re-inserting them into the deposit port 211. Becomes possible.

(Bill receiving / dispensing machine with stack type storage unit)
The technology disclosed herein is not limited to being applied to the banknote pay-in / pay-out device 1 provided with a winding-type storage unit. The present invention is also applicable to a banknote pay-in / pay-out device having a stack type storage unit.

FIG. 15 illustrates the banknote pay-in / pay-out device 10 provided with a stack-type storage unit. The bill depositing and dispensing machine 10 (in the illustrated example the first to fourth) multiple has a storage cassette ₃₃ -1 _{to 33 -4-stack.} The stack type storage cassette 33 has a stage 331 that can move in the vertical direction inside. Bills are stacked on the stage 331 in the vertical direction. These stack type storage cassettes 33 are configured to be able to feed out stored banknotes. Since the configuration of the stack type storage cassette 33 is known, a detailed description of the configuration is omitted.

  Even in the stack type storage cassette 33, it is not preferable to repeatedly store and feed out the banknotes in a state close to the full amount. In other words, at the time of feeding, the stacked banknotes are pressed in the stacking direction and the top sheet is fed, but in a state close to full, the banknotes are stacked high and the pressing becomes unstable. That's why. Further, the bill cannot be paid out stably. In particular, when the composite material banknotes are stacked, the thickness of the banknotes is not constant, and thus the banknotes stacked on the stage 331 may be inclined, and the above-described instability increases. Further, when the stack type storage cassette 33 is almost full, storage of bills may be unstable.

Therefore, the above configuration 1 is also adopted in the banknote pay-in / pay-out device 10 including the stack type storage cassette 33. That is, the control unit 513 sets the storage amount of the storage cassette (for example, the first storage cassette 33 _-1 ) so that the storage and the feeding of the banknotes are not repeated in a state where the storage amount of the storage cassette 33 is close to the full amount. When the preset first storage amount is reached, storing of the banknotes in the first storage cassette _33-1 is prohibited until the preset second storage amount is reached. To feed the banknotes from the first storage module 33 _-1 permits. The first storage cassette 33 _-1 is set to pay-out dedicated storage cassette.

At this time, the control unit 513, the second storage cassette 33 _-2 accommodating the same bills in the first storage cassette 33 _-1 is set in the storage dedicated storage cassette. That is, the second storage cassette 33 _-2, while the banknote storage is permitted, feeding the paper money is prohibited.

By the bill is fed out from the first storage cassette 33 _-1, when the storage amount reaches the second amount of storage, the control unit 513, a first storage cassette 33 _-1, from the supply dedicated storage cassette, Switch to a storage cassette dedicated to storage. The control unit 513 also the second storage cassette 33 _-2 from the storage dedicated storage cassette, switches the feeding dedicated storage cassette. First storage cassette 33 _-1 is allowed banknotes accommodated, feeding the paper money is prohibited. Second storage cassette 33 _-2 allowed feeding banknotes, banknote storage is inhibited. In this way, even in the banknote pay-in / pay-out device 10 including the stack type storage cassette 33, it is possible to prevent the storage cassette 33 from repeatedly storing and feeding out banknotes when the storage cassette 33 is almost full.

As described above, before the first storage cassette 33 _-1 set in the exclusive feeding reaches the second amount of storage, the second storage cassette 33 set in the storage specific _-2, first storage amount to when it reaches, in its timing, to the first storage cassette 33 _-1 housing dedicated storage cassette may switch the second storage cassette 33 _-1 to feeding dedicated storage cassette.

  In addition, each of the plurality of storage cassettes 33 is configured to permit both storage and feeding of bills, and when one of the storage cassettes 33 reaches the first storage amount, the storage cassettes 33 are The storage of the banknotes may be prohibited and the feeding of the banknotes may be permitted until the second storage amount is reached, while the other storage cassette 33 may permit both the storage and feeding of the banknotes.

  The banknote pay-in / pay-out device 10 provided with the stack type storage cassette 33 may also adopt the above configuration 4. In the stack-type storage cassette 33, if the composite material banknotes are included in a large amount below the stacked banknotes, the stacked banknotes tend to have a large inclination and are likely to be unstable. Further, in the stacked banknotes, when the unevenness of the composite material is stacked at the same position, the inclination of the stacked banknotes is further increased. Therefore, also in the banknote pay-in / pay-out device 10 provided with the stack type storage cassette 33, the control unit 513 controls the composite material banknote according to the number of stored storage cassettes 33, the front and back and direction of the composite material banknote, and the position thereof. May not be stored in the storage cassette 33.

  In addition, although the storage cassette 33 which stores banknotes stacked vertically and stores them is shown here, a storage cassette which stores banknotes in a horizontal direction and stores them may be used.

  The technology disclosed herein is not limited to being applied to the above-described banknote pay-in / pay-out device. The present invention can be widely applied to a bill processing apparatus that includes a winding storage unit and / or a stack storage unit that stores bills and that stores and feeds bills.

  In addition, the object to be stored and fed in the storage unit is not limited to paper money, but includes all kinds of paper including gift certificates, securities such as checks and gift certificates, and the technology disclosed herein is a paper processing apparatus. Applicable to
