Patent Description:
In the related art, there is known a banknote processing apparatus that dispenses a banknote stored in a storage unit (see, for example, Patent Literature (hereinafter, referred to as "PTL") <NUM>). In the banknote processing apparatus PTL <NUM>, a recognition unit recognizes a banknote transported from a banknote cassette when a banknote is dispensed. In the banknote processing apparatus, a customer unit stacks banknotes whose recognition result is normal, and a temporary storage unit stacks banknotes whose recognition result is abnormal.

In the banknote processing apparatus, when banknotes in a dispensing amount are stacked in the customer unit, the recognition unit re-recognizes the banknotes stacked in the temporary storage unit. In the banknote processing apparatus, banknotes whose re-recognition result is normal are stacked in banknote cassettes in accordance with denominations of the banknotes, and banknotes whose re-recognition result is abnormal are stacked in a reject cassette.

<CIT> discloses a money handling apparatus including: a money storage unit configured to store money; a locking unit configured to limit access to the money storage unit; and a control unit configured to give unlock permission to unlock the locking unit to at least one of a plurality of qualified persons who are qualified to unlock the locking unit, and to perform a process involving change of the qualified person (cf.

<CIT> discloses a cash processing apparatus comprising: an outlet for discharging a bill; a recognition unit for recognizing a bill; a conveying unit for conveying a bill; a temporary holding unit for temporarily storing a bill; a bill cassette capable of storing bills; and a control unit for controlling the conveyance unit so that the separation of the bill from the temporary holding unit is stopped and the bill separated from the temporary holding unit is conveyed to the payout port by controlling the recognition unit so that the conveyance direction of the bill is opposite to that of the bill, in the case where the bill being conveyed is recognized as abnormal by the recognition unit during the storing operation of the bill separated from the temporary holding unit into the bill cassette (cf. Claim <NUM>).

However, recognition results may be unstable depending on the characteristics of banknotes. For example, a banknote recognized as normal at a time of re-recognition is recognized as a banknote as a dispensing object by a recognition unit at a time of the next or subsequent dispensing, but may be recognized as abnormal again by the recognition unit when the banknote is recognized at the time of the next or subsequent dispensing. In this case, the dispensing efficiency decreases.

An object of the present disclosure is to provide an sheet processing apparatus and a sheet processing method that are capable of suppressing a decrease in the discharging efficiency of a normal sheet.

Further embodiments of the present invention are described in the dependent claims.

According to the sheet processing apparatus and the sheet processing method of the present disclosure, it is possible to suppress a decrease in the discharging efficiency of a normal sheet.

The present disclosure is implemented in discharging processing of a sheet processing apparatus. The discharging processing is processing in which a sheet stored in a storage unit of the sheet processing apparatus is discharged from an outlet section. The outlet section is, for example, a dispensing unit. The storage unit is, for example, a recycling storage apparatus. In the discharging processing, a sheet fed out from the storage unit is transported to a recognition unit by a transport unit and is recognized by the recognition unit. A normal note is discharged from the outlet section. An abnormal note is stored in a temporary storage unit. The discharging processing is, for example, dispensing processing. Further, the discharging processing may be collection processing. The collection processing is processing which is performed by a manager who manages the sheet processing apparatus, and in which a sheet in the storage unit is discharged from the outlet section and is collected outside the sheet processing apparatus.

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

In the embodiments described below, a description will be given mainly of a case where the discharging processing is dispensing processing, but the dispensing processing can be replaced with collection processing.

First, a configuration of a banknote processing apparatus in Embodiment <NUM> of the present disclosure will be described. <FIG> is a block diagram illustrating an overview of an internal configuration of the banknote processing apparatus. <FIG> is a schematic diagram illustrating an overview of an internal configuration of a recycling storage apparatus. <FIG> is a schematic diagram illustrating an overview configuration of a sensor that forms the recycling storage apparatus. <FIG> is a schematic diagram illustrating a configuration of an abnormal note list. The arrangements of the respective configurations of the banknote processing apparatus or the like may be described with the direction indicated in <FIG>.

A banknote processing apparatus <NUM> indicated in <FIG> is an example of the sheet processing apparatus. The banknote processing apparatus <NUM> is installed, for example, in a lobby of a financial institution such as a bank or at a customer service counter thereof. Note that, the banknote processing apparatus <NUM> may be installed at a settlement counter of a store such as a retail store or in a back office thereof. The banknote processing apparatus <NUM> dispenses a banknote in accordance with its setting. The banknote is an example of the sheet. The banknote processing apparatus <NUM> comprises a housing <NUM>.

The banknote processing apparatus <NUM> further comprises: a dispensing unit <NUM>; a recognition unit <NUM>; a first storage unit <NUM>; a second storage unit <NUM>; a temporary storage unit <NUM>; a transport unit <NUM>; and a control unit <NUM>. The transport unit <NUM> connects the dispensing unit <NUM>, the recognition unit <NUM>, the first storage unit <NUM>, the second storage unit <NUM>, and the temporary storage unit <NUM>, and transports a banknote. The recognition unit <NUM> may be provided on the transport unit <NUM>. The control unit <NUM> may be provided outside the housing <NUM>. The banknote processing apparatus <NUM> may comprise an operation unit (not illustrated) and a memory unit <NUM> when needed. Further, the banknote processing apparatus <NUM> may comprise an interface for connecting an external operation unit and/or an external memory unit.

The dispensing unit <NUM> is an example of the outlet section. The dispensing unit <NUM> dispenses (discharges) a banknote recognized as normal in first recognition processing that is performed by the recognition unit <NUM> on a banknote stored in the first storage unit <NUM>. The dispensing unit <NUM> comprises an outlet <NUM>. The outlet <NUM> is provided so as to open upward in a front portion of the housing <NUM>. The dispensing unit <NUM> is configured so as to stack a plurality of banknotes in an overlapping state. Note that, a shutter that closes the outlet <NUM> may also be provided.

The recognition unit <NUM> generates signals indicating the denomination and authenticity of a banknote transported by the transport unit <NUM>. These signals are transmitted to the control unit <NUM>. The recognition unit <NUM> can also generate signals for detecting the fitness, attitude, and size of a banknote during transport and a space between banknotes during transport, and can transmit the signals to the control unit <NUM>.

The first storage unit <NUM> is configured so as to store a banknote as a dispensing object. The first storage unit <NUM> may be one recycling storage apparatus <NUM> as indicated by a solid line or may be a plurality of recycling storage apparatuses <NUM>. The recycling storage apparatus <NUM> is formed of a stack-type storing unit that stores banknotes in an overlapping manner. The recycling storage apparatus <NUM> takes in and stores banknotes one by one, and feeds out the stored banknotes one by one. The denominations of banknotes to be stored in the recycling storage apparatus <NUM> are set in advance. Note that, the recycling storage apparatus <NUM> may also be formed of a tape-type storing unit that uses a strip-shaped tape attached to the outer peripheral surface of a drum to wind a banknote on the drum together with the tape. Further, the first storage unit <NUM> (the recycling storage apparatus <NUM>) may also be configured such that the first storage unit <NUM> can be set in the housing <NUM> and can be taken out from the housing <NUM>, by opening a door provided in the housing <NUM>.

The banknote processing apparatus <NUM> may manage a number of banknotes stored in the first storage unit <NUM>. Further, the banknote processing apparatus <NUM> may manage a storage state of banknotes stored in the first storage unit <NUM>. For example, as the storage state, it is possible to exemplify an approximate number of stored banknotes (although not an exact number of banknotes), a storage ratio (a ratio of a number of stored banknotes to a number of banknotes that can be stored), or the like, but the storage state is not limited thereto. The first storage unit <NUM> may comprise an apparatus that determines a storage state of banknotes stored inside the first storage unit <NUM>. Here, an example of a specific configuration of the recycling storage apparatus <NUM> will be described. As illustrated in <FIG>, the recycling storage apparatus <NUM> comprises a storage housing <NUM>, a stage <NUM>, a storage-transport mechanism <NUM>, and a detection unit <NUM>.

The stage <NUM> is configured so as to be capable of storing banknotes in an overlapping state. The stage <NUM> is configured to be vertically movable inside the storage housing <NUM> in accordance with an amount of banknotes to be stored. The stage <NUM> is provided so as to be located downward as the amount of banknotes to be stored is larger and so as to be located upward as the amount of banknotes to be stored is fewer. With such a configuration, the position of the topmost banknote on the stage <NUM> is constant or almost constant regardless of the amount of stored banknotes.

The storage-transport mechanism <NUM> is provided, for example, on an upper portion of the storage housing <NUM>. The storage-transport mechanism <NUM> places a banknote transported by the transport unit <NUM> on the stage <NUM>. The storage-transport mechanism <NUM> sends out the topmost banknote on the stage <NUM> to the transport unit <NUM>.

The detection unit <NUM> detects that a banknote storage state in the recycling storage apparatus <NUM> has become "near empty" or "empty". The "near empty" refers to a state in which an amount of banknotes is reduced, and the "empty" refers to a state in which an amount of banknotes is extremely reduced or <NUM>. The detection unit <NUM> comprises a sensor <NUM> and a detection plate <NUM>.

The sensor <NUM> is formed of, for example, a transmission-type optical sensor. The sensor <NUM> is fixed above the center of the storage housing <NUM>, for example. The sensor <NUM> comprises a light emission unit (not illustrated) and a light reception unit (not illustrated). The sensor <NUM> emits a detection light from the light emission unit toward the light reception unit, and outputs a voltage signal in accordance with a light reception intensity at the light reception unit to the control unit <NUM>. The voltage signal becomes larger as the light reception intensity is higher.

The detection plate <NUM> is fixed to the stage <NUM>. The detection plate <NUM> is formed to have a vertically extending shape. As illustrated in <FIG>, the detection plate <NUM> comprises a light shielding unit <NUM> located at the lower end, and a semi-light shielding unit <NUM> formed of the part other than the light shielding unit <NUM>. The height of the light shielding unit <NUM> (the distance in the vertical direction) is lower than the height of the semi-light shielding unit <NUM>. The light shielding unit <NUM> is configured so as to have a light shielding ratio of the detection light of the sensor <NUM> of <NUM>% or almost <NUM>%. The semi-light shielding unit <NUM> is configured so as to have a light shielding ratio of the detection light lower than that of the light shielding unit <NUM> and exceeding <NUM>%.

In a case where the recycling storage apparatus <NUM> stores a certain amount of banknotes and, as indicated by a solid line in <FIG>, the stage <NUM> is located in a lower portion of the storage housing <NUM>, the detection plate <NUM> is not located on the light axis of the detection light of the sensor <NUM>. Accordingly, as illustrated in <FIG>, the magnitude of a voltage signal outputted from the sensor <NUM> becomes a maximum value Vm. While the voltage signal having a magnitude of Vm is being acquired, the control unit <NUM> determines that the banknote storage state in the recycling storage apparatus <NUM> is neither "near empty" nor "empty".

When the stage <NUM> is raised and the semi-light shielding unit <NUM> of the detection plate <NUM> is located on the light axis of the detection light of the sensor <NUM> as a number of banknotes stored in the recycling storage apparatus <NUM> decreases, the magnitude of a voltage signal outputted from the sensor <NUM> becomes V1 smaller than the maximum value Vm and larger than <NUM>. While the voltage signal having a magnitude of V1 is being acquired, the control unit <NUM> determines that the number of banknotes stored in the recycling storage apparatus <NUM> is "near empty".

When the stage <NUM> is further raised and the light shielding unit <NUM> of the detection plate <NUM> is located on the light axis of the detection light of the sensor <NUM> as the number of banknotes stored in the recycling storage apparatus <NUM> further decreases, the magnitude of a voltage signal outputted from the sensor <NUM> becomes <NUM> or almost <NUM>. While the voltage signal having a magnitude of <NUM> or almost <NUM> is being acquired, the control unit <NUM> determines that the number of banknotes stored in the recycling storage apparatus <NUM> is "empty". Even in a case where the recycling storage apparatus <NUM> is formed of a tape-type storage unit, the recycling storage apparatus <NUM> may comprise an apparatus that determines a storage state of banknotes stored inside the recycling storage apparatus <NUM>. For example, the storage state may be determined by detecting the states of banknotes wound on a drum and of a tape. Further, the storage state may also be determined based on the drum diameter, the rotation amount of the drum, the diameter of a reel, the rotation amount of the reel or the movement amount of the tape.

The second storage unit <NUM> is configured to store a banknote which the control unit <NUM> determines cannot be dispensed based on a signal from the recognition unit <NUM>. The second storage unit <NUM> is formed of a stack-type or tape-type storage unit. Further, the second storage unit <NUM> may also be configured such that the second storage unit <NUM> can be set in the housing <NUM> and can be taken out from the housing <NUM>, by opening a door provided in the housing <NUM>.

The temporary storage unit <NUM> temporarily stores a banknote when the discharging processing is performed. The temporary storage unit <NUM> is formed of a stack-type or tape-type storage unit.

The transport unit <NUM> comprises a first transport path <NUM>, a second transport path <NUM>, and a third transport path <NUM>.

The first transport path <NUM> connects the temporary storage unit <NUM> and the second storage unit <NUM>. The first transport path <NUM> comprises an upper-side path <NUM> extending longitudinally (a first direction), a lower-side path <NUM> extending longitudinally below the upper-side path <NUM>, and a rear reversing path <NUM> extending vertically (a second direction) on the rear side to connect the upper-side path <NUM> and the lower-side path <NUM>. Here, the front side is a side on which the dispensing unit <NUM> of the banknote processing apparatus <NUM> is provided (the left side in <FIG>).

The temporary storage unit <NUM> is connected to the front end of the upper-side path <NUM>. The upper-side path <NUM> is provided with the recognition unit <NUM>. The recognition unit <NUM> is provided at any position. However, the recognition unit <NUM> may be provided, as an example, at a position at which a distance L1 of a part (a straight part) of the upper-side path <NUM>, where the part extends in the horizontal direction from the front end of the recognition unit <NUM> to the temporary storage unit <NUM>, is longer than a distance L2 of a part (a straight part) of the upper-side path <NUM>, where the part extends in the horizontal direction from the rear end of the recognition unit <NUM> to the rear reversing path <NUM>. Thus, both the distance from the front end of the recognition unit <NUM> to the temporary storage unit <NUM> and the distance from the rear end of the recognition unit <NUM> to the first storage unit <NUM> can be sufficiently large. The second storage unit <NUM> is connected to the front end of the lower-side path <NUM>.

The second transport path <NUM> connects the dispensing unit <NUM> and a position of the upper-side path <NUM>, where the position is on the front side of the recognition unit <NUM>. A connection part between the second transport path <NUM> and the upper-side path <NUM> is provided with a first diverter mechanism.

The third transport path <NUM> connects the recycling storage apparatus <NUM> and a position of the lower-side path <NUM>, where the position is on the rear side of a connection part between the lower-side path <NUM> and the temporary storage unit <NUM>. A connection part between the third transport path <NUM> and the lower-side path <NUM> is provided with a second diverter mechanism.

The first transport path <NUM> to the third transport path <NUM> are each formed of a combination of a roller, a belt wound on the roller, a motor that drives the roller, a sidewall, and the like. Tracking sensors that detect the passage of a banknote are provided at predetermined positions of the first transport path <NUM> to the third transport path <NUM>. The control unit <NUM> detects the position of a banknote based on detection signals from the tracking sensors, and controls the first diverter mechanism and the second diverter mechanism, thereby transporting the banknote to a predetermined configuration.

When needed, an operation unit that outputs an operation signal based on a setting inputted by an operator to the control unit <NUM> may be provided. Note that, the operation unit may be provided, for example, in the front portion of the housing <NUM> or may be formed of an operation apparatus connected to the banknote processing apparatus <NUM> by a cable or wirelessly.

When needed, the memory unit <NUM> may be provided. The memory unit <NUM> stores various data to which the control unit <NUM> refers. For example, the memory unit <NUM> may store an abnormal note list <NUM> as illustrated in <FIG>. The abnormal note list <NUM> is a list related to banknotes which are recognized as abnormal by the recognition unit <NUM> when the discharging processing is performed and which are therefore stored in the temporary storage unit <NUM>. The abnormal note list <NUM> comprises abnormal note information <NUM> corresponding to each banknote. When one banknote is stored in the temporary storage unit <NUM>, the abnormal note information <NUM> corresponding to the banknote is added to the abnormal note list <NUM> by the control unit <NUM>. When one banknote is fed out from the temporary storage unit <NUM>, the abnormal note information <NUM> corresponding to the banknote is deleted from the abnormal note list <NUM> by the control unit <NUM>. The abnormal note information <NUM> comprises storage order information <NUM> and abnormality factor information <NUM>.

The storage order information <NUM> indicates the order of storage of banknotes in the temporary storage unit <NUM>. The abnormality factor information <NUM> indicates a factor in causing a banknote to be recognized as abnormal. As the abnormality factor information <NUM> of one banknote, a plurality of factors may be stored. In the example of <FIG>, however, one factor corresponds to one banknote.

For example, the factor indicated by the abnormality factor information <NUM> may be an abnormality of a serial number. In a case where a serial number of a banknote read by the recognition unit <NUM> when the discharging processing is performed satisfies a predetermined condition, the banknote is determined as abnormal. The factor in causing the banknote to be recognized as abnormal is an abnormality of the serial number. The abnormality of a serial number may comprise "serial number-unreadable" and "serial number-disagreement". The abnormality of "serial number-unreadable" is an abnormality in which a serial number of a banknote cannot be at least partially read by the recognition unit <NUM>. Note that, the factor indicated by the abnormality factor information <NUM> may be "serial number-unreadable" in a case where characters more than a number of digits set in advance cannot be read or in a case where, regardless of a number of digits that cannot be read, a character of a particular digit cannot be read. The abnormality of "serial number-disagreement" is an abnormality in which a serial number read by the recognition unit <NUM> when the discharging processing is performed disagrees with a predetermined serial number. The predetermined serial number is a serial number stored in advance as a serial number of a banknote to be dispensed. For example, the predetermined serial number may be a serial number stored as a serial number in a serial number list to be described later.

In a case where the recognition unit <NUM> recognizes the fitness of a banknote, the factor indicated by the abnormality factor information <NUM> may comprise "fitness abnormality". This case indicates that a banknote is recognized as an unfit note by the recognition unit <NUM>. As factors in causing a banknote to be determined as an unfit note, it is possible to exemplify soiling, tearing, corner-folding (a folded corner of a banknote), and perforation.

A case where the factor indicated by the abnormality factor information <NUM> is "denomination abnormality" indicates that the denomination of a banknote recognized by the recognition unit <NUM> disagrees with a denomination specified based on the recycling storage apparatus <NUM> in which the banknote has been stored.

A case where the factor indicated by the abnormality factor information <NUM> is "transport abnormality" indicates that the transport interval of banknotes transported from the recycling storage apparatus <NUM> is equal to or less than a predetermined distance, or that banknotes are overlapped. The "transport abnormality" is detected by the recognition unit <NUM> or the tracking sensors.

The control unit <NUM> controls the banknote processing apparatus <NUM> in its entirety. The control unit <NUM> may also be referred to as a processor or a computer. Details of the processing of the control unit <NUM> will be described later.

Next, operations of the banknote processing apparatus <NUM> will be described. Note that, hereinafter, the banknote recognized as normal by the recognition unit <NUM> means a banknote for which no abnormality to be recorded as the abnormality factor information <NUM> in the abnormal note list <NUM> is detected. The banknote recognized as abnormal by the recognition unit <NUM> means a banknote for which an abnormality to be recorded as the abnormality factor information <NUM> is detected.

First, as an operation of the banknote processing apparatus <NUM>, dispensing processing that is an example of the discharging processing will be described. <FIG> is a flowchart illustrating the dispensing processing. Note that, a number of banknotes to be dispensed in the dispensing processing may be set and inputted by an operator, or may be determined by the control unit <NUM> based on a dispensing amount set and inputted by an operator.

When the control unit <NUM> realizes, based on an operation signal from the operation unit, a dispensing instruction of a banknote in a predetermined amount by an operator (step S1), the control unit <NUM> controls the recycling storage apparatus <NUM> of the first storage unit <NUM> such that one banknote is fed out (step S2).

The control unit <NUM> controls the transport unit <NUM> such that the banknote is transported to the recognition unit <NUM> via the third transport path <NUM>, the lower-side path <NUM>, the rear reversing path <NUM>, and the upper-side path <NUM>, and the recognition unit <NUM> performs the first recognition processing (step S3). The control unit <NUM> determines whether the banknote recognized in the first recognition processing is normal (step S4).

In a case where it has been determined that the banknote is a normal note (step S4: YES), the control unit <NUM> controls the transport unit <NUM> and the dispensing unit <NUM> such that the banknote passes through the upper-side path <NUM> and the second transport path <NUM> and is dispensed from the dispensing unit <NUM> (step S5). The control unit <NUM> determines whether a total amount of banknotes transported to the dispensing unit <NUM> has reached the dispensing amount, that is, whether the dispensing is completed (step S6). In a case where it has been determined that the dispensing is completed (step S6: YES), the control unit <NUM> ends the dispensing processing. In a case where it has been determined that the dispensing processing is not completed (step S6: NO), the control unit <NUM> performs the processing in step S2. Note that, the control unit <NUM> may determine that the dispensing is completed when realizing that the banknotes have been taken out from the dispensing unit <NUM>.

In a case where it has been determined that the banknote subjected to the first recognition processing is an abnormal note (step S4: NO), the control unit <NUM> controls the transport unit <NUM> and the temporary storage unit <NUM> such that the banknote passes through the upper-side path <NUM> and is stored in the temporary storage unit <NUM> (step S7). The control unit <NUM> adds the abnormal note information <NUM> of the banknote recognized as abnormal based on a result of the first recognition processing to the abnormal note list <NUM> (step S8), and performs the processing in step S2. Although the dispensing processing has been described thus far as an example of the discharging processing, the banknote movement is also the same in the case of the collection processing. For example, operations of the collection processing can be understood by replacing the dispensing amount described above with a collection amount or a number of collected banknotes.

Next, storage processing of a banknote stored in the temporary storage unit <NUM> will be described. <FIG> is a flowchart illustrating first storage processing and second storage processing. The first storage processing and the second storage processing are examples of the storage control processing.

When the discharging processing is completed, the control unit <NUM> may perform the first storage processing or the second storage processing. Hereinafter, a description will be given assuming that the dispensing processing as the discharging processing is completed. First, a description will be given of the first storage processing.

As illustrated in <FIG>, the control unit <NUM> determines whether a banknote is stored in the temporary storage unit <NUM> (step S11). In a case where it has been determined that no banknote is stored in the temporary storage unit <NUM> (step S11: NO), the control unit <NUM> ends the storage processing. In a case where it has been determined that a banknote is stored in the temporary storage unit <NUM> (step S11: YES), the control unit <NUM> performs condition determination processing (step S12).

In the condition determination processing, the control unit <NUM> determines whether a predetermined condition is satisfied. As the predetermined condition, it is possible to exemplify a condition <NUM>-<NUM> and a condition <NUM>-<NUM> described below. In the condition determination processing, the control unit <NUM> may determine only condition <NUM>-<NUM> or both the conditions. In the condition determination processing, the control unit <NUM> may use both the conditions <NUM>-<NUM> and <NUM>-<NUM> as determination objects.

The condition <NUM>-<NUM> is a condition related to the number of banknotes stored in the first storage unit <NUM>. For example, the condition <NUM>-<NUM> is a condition that the number of banknotes stored in the recycling storage apparatus <NUM> at a time when the dispensing processing ends is equal to or less than a first threshold value. In a case where the number of banknotes stored in the recycling storage apparatus <NUM> is equal to or less than the first threshold value, the control unit <NUM> determines that the predetermined condition is satisfied. In a case where the number of banknotes stored in the recycling storage apparatus <NUM> exceeds the first threshold value, the control unit <NUM> determines that the predetermined condition is not satisfied. Note that, the condition <NUM>-<NUM> may also be a condition that the number of banknotes stored in the first storage unit <NUM> at a time when a predetermined banknote is ejected from the temporary storage unit <NUM> is equal to or less than the first threshold value. Note that, the control unit <NUM> may realize the number of banknotes stored in the recycling storage apparatus <NUM> based on a counting result of a number of banknotes put into and taken out from the recycling storage apparatus <NUM> and/or based on a detection result of the weight of banknotes. Further, the control unit <NUM> may determine whether not the number of banknotes stored in the recycling storage apparatus <NUM>, but the weight of banknotes is equal to or less than the first threshold value.

The control unit <NUM> may realize the banknote storage state in the recycling storage apparatus <NUM> based on a detection result of the sensor <NUM>. In this case, when the storage state detected by the sensor <NUM> is "empty" or "near empty", the control unit <NUM> determines that the condition related to the number of stored banknotes is satisfied, and when the storage state is neither "empty" nor "near empty", the control unit <NUM> may determine that the condition related to the number of stored banknotes is not satisfied.

The condition <NUM>-<NUM> is a condition related to a number of banknotes stored in the temporary storage unit <NUM>. For example, the condition <NUM>-<NUM> is a condition that the number of banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends is equal to or less than a second threshold value. In a case where the number of banknotes stored in the temporary storage unit <NUM> is equal to or less than the second threshold value, the control unit <NUM> determines that the predetermined condition is satisfied. In a case where the number of banknotes stored in the temporary storage unit <NUM> exceeds the second threshold value, the control unit <NUM> determines that the predetermined condition is not satisfied. Note that, the condition <NUM>-<NUM> may also be a condition that the number of banknotes stored in the temporary storage unit <NUM> at a time when a predetermined banknote is ejected from the temporary storage unit <NUM> is equal to or less than the second threshold value.

The control unit <NUM> may realize the number of banknotes stored in the temporary storage unit <NUM> based on a number of the abnormal note information <NUM> in the abnormal note list <NUM> at the time when the dispensing processing ends and/or based on a content of the storage order information <NUM>.

When the condition determination processing is performed, the control unit <NUM> controls the temporary storage unit <NUM> such that one banknote is fed out (step S13). The control unit <NUM> deletes the abnormal note information <NUM> corresponding to the banknote, which has been fed out, from the abnormal note list <NUM> (step S14). The control unit <NUM> controls the transport unit <NUM> such that the banknote is transported to the recognition unit <NUM> via the upper-side path <NUM>, and the recognition unit <NUM> performs second recognition processing (step S15). The content of the second recognition processing is the same as that of the first recognition processing. The control unit <NUM> determines whether it has been determined in the condition determination processing that the predetermined condition is satisfied (step S16).

In a case where it has been determined that the predetermined condition is satisfied (step S16: YES), the control unit <NUM> controls the transport unit <NUM> and the second storage unit <NUM> such that the banknote passes through the upper-side path <NUM>, the rear reversing path <NUM>, and the lower-side path <NUM> and is stored in the second storage unit <NUM> (step S17). That is, the control unit <NUM> causes the banknote to be stored in the second storage unit <NUM> regardless of a recognition result in the second recognition processing.

The control unit <NUM> determines whether a banknote remains in the temporary storage unit <NUM> (step S18). The control unit <NUM> may determine whether a banknote remains in the temporary storage unit <NUM>, for example, based on a counting result of a number of banknotes put into and taken out from the temporary storage unit <NUM> and/or based on a content of the abnormal note list <NUM>. In a case where it has determined that no banknote remains in the temporary storage unit <NUM> (step S18: NO), the control unit <NUM> ends the storage processing. In a case where it has been determined that a banknote remains in the temporary storage unit <NUM> (step S18: YES), the control unit <NUM> performs the processing in step S13 as indicated by a solid line.

In a case where it has been determined in the condition determination processing that the predetermined condition is not satisfied (step S16: NO), the control unit <NUM> determines whether a result of the second recognition processing of the banknote is normal (step S19). In a case where it has been determined that the result of the second recognition processing is normal (step S19: YES), the control unit <NUM> controls the transport unit <NUM> and the first storage unit <NUM> such that the banknote passes through the upper-side path <NUM>, the rear reversing path <NUM>, the lower-side path <NUM>, and the third transport path <NUM> and is stored in the first storage unit <NUM> (step S20). The control unit <NUM> performs the processing in step S18. In a case where it has been determined that the result of the second recognition processing is abnormal (step S19: NO), the control unit <NUM> performs the processing in step S17. That is, the control unit <NUM> causes the banknote to be stored in the second storage unit <NUM>.

Next, the second storage processing will be described. The first storage processing and the second storage processing are common except the following two points:.

The difference <NUM>-<NUM> will be described. In the condition determination processing in step S12, the control unit <NUM> determines whether a condition <NUM>-<NUM> described below is satisfied.

The condition <NUM>-<NUM> is a condition related to a factor in causing a banknote to be recognized as abnormal in the first recognition processing. For example, the condition <NUM>-<NUM> is a condition that the factor in causing a banknote to be recognized as abnormal is an abnormality of a serial number ("serial number-unreadable" or "serial number-disagreement"). In a case where an abnormality of a banknote is an abnormality of a serial number, the control unit <NUM> determines that only the banknote is a banknote for which the predetermined condition is satisfied. In a case where an abnormality of a banknote is an abnormality other than an abnormality of a serial number, the control unit <NUM> determines that only the banknote is a banknote for which the predetermined condition is not satisfied. The control unit <NUM> may also realize an abnormality factor of a banknote based on a content of the abnormality factor information <NUM> in the abnormal note list <NUM>.

The difference <NUM>-<NUM> will be described. In a case where it has been determined in step S18 that a banknote remains in the temporary storage unit <NUM>, the control unit <NUM> performs the processing in step S12 as indicated by a two-dot chain line in <FIG>. That is, in the first storage processing, a result of the condition determination processing in step S12 performed once is applied to all banknotes stored in the temporary storage unit <NUM>, whereas in the second storage processing, the condition determination processing in step S12 is performed on each banknote stored in the temporary storage unit <NUM> and it is determined whether the predetermined condition is satisfied.

In the first storage processing and the second storage processing, the processing in step S19 that is performed following step S16 is an example of the first processing. The processing in steps S19, S20, and S17 that are performed following step S16 are examples of the second processing.

Note that, in the first storage processing and the second storage processing, the condition determination processing may be performed after the second recognition processing is performed. In this case, the control unit <NUM> may perform the processing in steps S12 to S15 in the order of step S13, step S15, step S12, and step S14, or in the order of step S13, step S12, step S14, and step S15.

Embodiment <NUM> described above exhibits working effects as described below.

When a banknote stored in the temporary storage unit <NUM> in the dispensing processing, that is, a banknote recognized as abnormal in the first recognition processing is determined as normal in the second recognition processing, the banknote is stored in the first storage unit <NUM> and is subjected to the first recognition processing at a time of the next dispensing processing. A banknote that is stored in the temporary storage unit <NUM> and is then returned to the first storage unit <NUM> may be recognized as an abnormal note again in the first recognition processing and may be stored in the temporary storage unit <NUM>. When a banknote that is stored in the temporary storage unit <NUM> and is then returned to the first storage unit <NUM> is stored in the temporary storage unit <NUM> again as described above, the dispensing efficiency may decrease.

To suppress a decrease in the dispensing efficiency as described above, the control unit <NUM> causes a banknote stored in the temporary storage unit <NUM> to be stored in the second storage unit <NUM> in a case where the predetermined condition is satisfied in the first storage processing or the second storage processing. In a case where the predetermined condition is not satisfied, the control unit <NUM> causes, of banknotes stored in the temporary storage unit <NUM>, a banknote recognized as normal in the second recognition processing to be stored in the first storage unit <NUM>, and causes, of the banknotes stored in the temporary storage unit <NUM>, a banknote recognized as abnormal in the second recognition processing to be stored in the second storage unit <NUM>.

First, a description will be given of a reason why it is possible to suppress a decrease in the dispensing efficiency in a case where the predetermined condition in the first storage processing further includes the condition <NUM>-<NUM>.

It is considered that banknotes stored in the first storage unit <NUM> at the time when the dispensing processing ends comprise a predetermined proportion of banknotes that are recognized as normal in the first recognition processing. Accordingly, in a case where the number of banknotes stored in the first storage unit <NUM> exceeds the first threshold value, the first storage unit <NUM> highly likely comprises more banknotes that are recognized as normal in the first recognition processing, in comparison with a case where the number of banknotes stored in the first storage unit <NUM> is equal to or less than the first threshold value. Accordingly, in a case where the number of banknotes stored in the first storage unit <NUM> exceeds the first threshold value, it is possible to complete the dispensing by returning all banknotes stored in the temporary storage unit <NUM> to the first storage unit <NUM> and by dispensing, even when the returned banknotes are recognized as abnormal in the first recognition processing, other banknotes stored in the first storage unit <NUM>.

In a case where the number of banknotes stored in the first storage unit <NUM> at the time when the dispensing processing ends is equal to or less than the first threshold value, on the other hand, the dispensing may not be completed by returning all banknotes stored in the temporary storage unit <NUM> to the first storage unit <NUM> when the returned banknotes are recognized as abnormal in the first recognition processing. In this case, even when other banknotes stored in the first storage unit <NUM> are dispensed, a dispensing amount may not be reached.

Accordingly, in a case where the number of banknotes stored in the first storage unit <NUM> at the time when the dispensing processing ends is equal to or less than the first threshold value, the control unit <NUM> causes all banknotes stored in the temporary storage unit <NUM> to be stored in the second storage unit <NUM>, and excludes the banknotes from dispensing objects. After such processing, an operator is capable of replenishing the first storage unit <NUM> with banknotes based on the number of banknotes stored in the first storage unit <NUM> after the first storage processing. Accordingly, in the dispensing processing after the first storage processing, it is possible to suppress a situation in which the dispensing is not completed, and it is possible to suppress a decrease in the dispensing efficiency.

Next, a description will be given of a reason why it is possible to suppress a decrease in the dispensing efficiency in a case where the predetermined condition in the first storage processing is the condition <NUM>-<NUM>.

It is considered that banknotes stored in the temporary storage unit <NUM> comprise a predetermined proportion of banknotes that are recognized as normal in a case where the first recognition processing is performed again. Accordingly, in a case where the number of banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends exceeds the second threshold value, the temporary storage unit <NUM> highly likely comprises more banknotes that are recognized as normal in a case where the first recognition processing is performed again, in comparison with a case where the number of banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends is equal to or less than the second threshold value. Accordingly, a case where all banknotes stored in the temporary storage unit <NUM> are returned to the first storage unit <NUM> results in an increase in, of the returned banknotes, banknotes to be dispensed, and does not lead to a decrease in the dispensing efficiency.

In a case where the number of banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends is equal to or less than the second threshold value, on the other hand, the temporary storage unit <NUM> highly likely comprises fewer banknotes that are recognized as normal in a case where the first recognition processing is performed again, in comparison with a case where the number of banknotes stored in the temporary storage unit <NUM> exceeds the second threshold value. Accordingly, a case where all banknotes stored in the temporary storage unit <NUM> are returned to the first storage unit <NUM> may result in a decrease in, of the returned banknotes, banknotes to be dispensed, in comparison with a case where the number of banknotes stored in the temporary storage unit <NUM> exceeds the second threshold value. That is, banknotes recognized as abnormal in the first recognition processing may increase and the dispensing efficiency may decrease.

Accordingly, in a case where the number of banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends is equal to or less than the second threshold value, the control unit <NUM> causes all banknotes stored in the temporary storage unit <NUM> to be stored in the second storage unit <NUM>, and excludes the banknotes from dispensing objects. The control unit <NUM> performs such processing, and thus, it is possible to suppress a decrease in the dispensing efficiency.

Next, a description will be given of a reason why it is possible to suppress a decrease in the dispensing efficiency in a case where the condition in the second storage processing is the condition <NUM>-<NUM>.

The recognition unit <NUM> performs recognition processing of a banknote by using an image sensor or the like. However, even in a case where the same banknote is recognized, different recognition results may be obtained when a distance between the image sensor and a recognition part of the banknote varies. For example, a serial number, and tearing, soiling, perforation and the like of a banknote may be or may not be recognizable. Banknote warpage is considered to be a reason why the distance between the image sensor and the recognition part of a banknote varies.

For example, when a banknote passes through a bent part of a transport path, the banknote warps in accordance with the shape of the transport path. This banknote warpage gradually disappears as a transport distance on the transport path that is not bent increases.

When the first recognition processing is performed, a banknote is transported from the first storage unit <NUM> to the recognition unit <NUM> via the third transport path <NUM>, the rear reversing path <NUM>, and the upper-side path <NUM>. Since the direction in which the rear reversing path <NUM> extends differs from the direction in which the upper-side path <NUM> extends, the banknote warps when transported from the rear reversing path <NUM> to the upper-side path <NUM>. Thereafter, the banknote is transported on the upper-side path <NUM> that horizontally extends, but may be subjected to the recognition by the recognition unit <NUM> in a state in which the warpage does not disappear since the transport distance to the recognition unit <NUM> is short.

When the second recognition processing is performed, on the other hand, a banknote is transported from the temporary storage unit <NUM> to the recognition unit <NUM> via the upper-side path <NUM>. That is, the direction in which the banknote passes through the recognition unit <NUM> varies between the first recognition processing and the second recognition processing. Assuming that a banknote is bent when stored in the temporary storage unit <NUM>, the banknote is transported on the upper-side path <NUM> that horizontally extends, and the transport distance to the recognition unit <NUM> is longer than that at a time of the first recognition processing. Accordingly, the banknote is highly likely subjected to recognition by the recognition unit <NUM> in a state in which the warpage is smaller than that at the time of the first recognition processing.

A case where banknote warpage at a time of the second recognition processing is smaller than that at the time of the first recognition processing may cause a situation in which the serial number that is not recognized in the first recognition processing is recognized in the second recognition processing. When such a situation occurs, the banknote reciprocates between the first storage unit <NUM> and the temporary storage unit <NUM> when the dispensing processing and the storage processing are performed, and the dispensing efficiency may decrease.

Accordingly, in a case where a factor in causing a banknote to be recognized as abnormal is an abnormality of a serial number ("serial number-unreadable"), the control unit <NUM> causes the banknote to be stored in the second recognition <NUM>, and excludes the banknote from dispensing objects. The control unit <NUM> performs such processing, and thus, it is possible to suppress a decrease in the dispensing efficiency.

The control unit <NUM> causes the second recognition processing to be performed on all banknotes stored in the temporary storage unit <NUM> regardless of whether the banknotes are banknotes for which the conditions <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> are satisfied. Accordingly, there is no need to change the control of the recognition unit <NUM> depending on whether the banknotes are banknotes for which the conditions <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> are satisfied.

The control unit <NUM> causes a banknote to pass through the upper-side path <NUM>, the rear reversing path <NUM>, and the lower-side path <NUM> regardless of whether the banknote is a banknote for which the conditions <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> are satisfied. Accordingly, it is possible to suppress a decrease in the dispensing efficiency in a state in which a change in a banknote transport route is suppressed to the minimum.

Next, a configuration of a banknote processing apparatus in Embodiment <NUM> of the present disclosure will be described. <FIG> is a schematic diagram illustrating a configuration of an abnormal note list. Note that, a banknote processing apparatus 1A in Embodiment <NUM> is an example of the banknote processing apparatus <NUM> of Embodiment <NUM>. The same configurations as those of the banknote processing apparatus <NUM> of Embodiment <NUM> will be denoted by the same reference signs, and descriptions thereof will be simplified or omitted.

The banknote processing apparatus 1A of Embodiment <NUM> and the banknote processing apparatus <NUM> of Embodiment <NUM> that are illustrated in <FIG> differ in that the banknote processing apparatus 1A comprises a first storage unit 2A instead of the first storage unit <NUM>, in that the banknote processing apparatus 1A comprises a transport unit 4A instead of the transport unit <NUM>, in the content of the abnormal note list stored in the memory unit <NUM>, and in the processing content of the control unit <NUM>.

As indicated by a solid line and a two-dot chain line in <FIG>, the first storage unit 2A comprises a plurality of recycling storage apparatuses <NUM>. Note that, hereinafter, one of two recycling storage apparatuses <NUM> may be referred to as "first recycling storage apparatus 21A", and the other thereof may be referred to as "second recycling storage apparatus 21B". The denominations of banknotes that are stored in the first recycling storage apparatus 21A and the second recycling storage apparatus 21B are set differently in advance, respectively. Note that, at least one of the first recycling storage apparatus 21A and the second recycling storage apparatus 21B may be formed of a tape-type storing unit that uses a strip-shaped tape attached to the outer peripheral surface of a drum to wind a banknote on the drum together with the tape. Further, three or more recycling storage apparatuses <NUM> may form the first storage unit 2A. In this case, the denominations of banknotes that are stored in the respective recycling storage apparatuses <NUM> preferably differ from each other.

The transport unit 4A comprises the first transport path <NUM> to the third transport path <NUM> indicated by solid lines in <FIG>, and a fourth transport path <NUM> indicated by a two-dot chain line in <FIG>.

The third transport path <NUM> connects the lower-side path <NUM> and the first recycling storage apparatus 21A. The fourth transport path <NUM> connects the second recycling storage apparatus 21B and a position of the lower-side path <NUM>, where the position is on the rear side of a connection part between the lower-side path <NUM> and the third transport path <NUM>. A connection part between the fourth transport path <NUM> and the lower-side path <NUM> is provided with a third diverter mechanism. In the same manner as the first transport path <NUM> to the third transport path <NUM>, the fourth transport path <NUM> is formed of a combination of a roller, a belt, a motor, a sidewall, and the like. A tracking sensor(s) that detect(s) the passage of a banknote is/are provided at a predetermined position(s) of the fourth transport path <NUM>. The control unit <NUM> detects the position of a banknote based on detection signals from the tracking sensors, and controls the first diverter mechanism to the third diverter mechanism, thereby transporting the banknote to a predetermined configuration.

The memory unit <NUM> stores an abnormal note list 141A as illustrated in <FIG>. The abnormal note list 141A comprises abnormal note information 142A corresponding to each banknote. The abnormal note information 142A comprises the storage order information <NUM>, the abnormality factor information <NUM>, and feeding source information 145A. The feeding source information 145A indicates the recycling storage apparatus <NUM> (the first recycling storage apparatus 21A or the second recycling storage apparatus 21B) in which a banknote has been stored before the discharging processing starts.

Next, operations of the banknote processing apparatus 1A will be described. Note that, the dispensing processing as an example of the discharging processing and the second storage processing are the same as those in Embodiment <NUM>. Accordingly, descriptions thereof will be omitted, and the first storage processing will be described. Note that, descriptions of the same processing as the first storage processing of Embodiment <NUM> will be simplified or omitted.

The first storage processing of Embodiment <NUM> and the first storage processing of Embodiment <NUM> are common except the following three points:.

The difference <NUM>-<NUM> will be described. In the condition determination processing in step S12 illustrated in <FIG>, the control unit <NUM> determines whether conditions <NUM>-<NUM> and <NUM>-<NUM> described below are satisfied. In the condition determination processing, the control unit <NUM> may also determine only one of the conditions <NUM>-<NUM> and <NUM>-<NUM> or both the conditions. In the condition determination processing, the control unit <NUM> may use both the conditions <NUM>-<NUM> and <NUM>-<NUM> as determination objects, determine that the predetermined condition is satisfied in a case where one of the conditions of the determination objects is satisfied, and determine that the predetermined condition is not satisfied in a case where all the conditions of the determination objects are not satisfied.

The condition <NUM>-<NUM> is a condition related to a number of banknotes stored in the first storage unit 2A. For example, the condition <NUM>-<NUM> is a condition that the number of banknotes stored in the recycling storage apparatus <NUM>, in which a banknote (a storage object banknote) that is to be fed out from the temporary storage unit <NUM> and is to be stored in the first storage unit 2A or the second storage unit <NUM> has been originally (previously) stored, is equal to or less than a first threshold value at the time when the dispensing processing ends. Note that, the first threshold value in Embodiment <NUM> may be the same as or different from the first threshold value in Embodiment <NUM>. Further, the condition <NUM>-<NUM> may also be a condition that the number of banknotes stored in the recycling storage apparatus <NUM> in which a storage object banknote has been originally stored is equal to or less than the first threshold value at a time when the storage object banknote is fed out.

When the condition determination processing in step S12 is performed, the control unit <NUM> realizes, based on the abnormal note list 141A, the recycling storage apparatus <NUM> (the first recycling storage apparatus 21A or the second recycling storage apparatus 21B) in which a banknote (a storage object banknote) to be fed out from the temporary storage unit <NUM> has been originally stored. For example, in a case where the realized recycling storage apparatus <NUM> is the first recycling storage apparatus 21A, the control unit <NUM> determines that the predetermined condition is satisfied when a number of banknotes stored in the first recycling storage apparatus 21A at the time when the dispensing processing ends is equal to or less than the first threshold value, and the control unit <NUM> determines that the predetermined condition is not satisfied when the number of banknotes stored in the first recycling storage apparatus 21A at the time when the dispensing processing ends exceeds the first threshold value.

The condition <NUM>-<NUM> is a condition related to the number of banknotes stored in the temporary storage unit <NUM>. For example, the condition <NUM>-<NUM> is a condition that, of banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends, a total number of banknotes having been stored in the recycling storage apparatus <NUM> that is the same recycling storage apparatus <NUM> in which a storage object banknote has been originally stored is equal to or less than a second threshold value. Note that, the second threshold value in Embodiment <NUM> may be the same as or different from the second threshold value in Embodiment <NUM>. Further, the condition <NUM>-<NUM> may be a condition that the total number of banknotes having been stored in the recycling storage apparatus <NUM> that is the same recycling storage apparatus <NUM> in which a storage object banknote has been originally stored is equal to or less than the first threshold value at a time when the storage object banknote is fed out.

When the condition determination processing in step S12 is performed, the control unit <NUM> realizes, based on the abnormal note list 141A, the recycling storage apparatus <NUM> (the first recycling storage apparatus 21A or the second recycling storage apparatus 21B) in which a banknote that is to be fed out from the temporary storage unit <NUM> has been stored. For example, in a case where the realized recycling storage apparatus <NUM> is the first recycling storage apparatus 21A, the control unit <NUM> determines that the predetermined condition is satisfied when, of banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends, a total number of banknotes having been stored in the first recycling storage apparatus 21A is equal to or less than the second threshold value, and the control unit <NUM> determines that the predetermined condition is not satisfied when, of the banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends, the total number of banknotes having been stored in the first recycling storage apparatus 21A exceeds the second threshold value.

The difference <NUM>-<NUM> will be described. In step S20, the control unit <NUM> causes a banknote determined as normal in the processing in step S19 to be stored in the first recycling storage apparatus 21A or the second recycling storage apparatus 21B (the first storage unit 2A) corresponding to the banknote.

The difference <NUM>-<NUM> will be described. In a case where it has been determined in step S18 that a banknote remains in the temporary storage unit <NUM>, the control unit <NUM> performs the processing in step S12 as indicated by the two-dot chain line in <FIG>. That is, in the first storage processing of Embodiment <NUM>, it is determined by the condition determination processing of step S12 performed once whether all banknotes stored in the temporary storage unit <NUM> are subjected to the second recognition processing in step S19, whereas in the first storage processing of Embodiment <NUM>, the condition determination processing in step S12 is performed a plurality of times, and it is determined whether each banknote stored in the temporary storage unit <NUM> is subjected to the second recognition processing in step S19.

Embodiment <NUM> described above exhibits, in addition to the same working effects as those exhibited by Embodiment <NUM>, working effects as described below.

When the condition determination processing is performed, the control unit <NUM> realizes the recycling storage apparatus <NUM> in which a storage object banknote has been originally stored, the control unit <NUM> determines that the predetermined condition is satisfied when the number of banknotes stored in the realized recycling storage apparatus <NUM> at the time when the dispensing processing ends is equal to or less than the first threshold value, and the control unit <NUM> determines that the predetermined condition is not satisfied when the number of banknotes stored in the realized recycling storage apparatus <NUM> at the time when the dispensing processing ends exceeds the first threshold value. Further, when the condition determination processing is performed, the control unit <NUM> realizes the recycling storage apparatus <NUM> in which a storage object banknote has been stored, the control unit <NUM> determines that the predetermined condition is satisfied when, of banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends, the total number of banknotes having been stored in the realized recycling storage apparatus <NUM> is equal to or less than the second threshold value, and the control unit <NUM> determines that the predetermined condition is not satisfied when, of the banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends, the total number of banknotes having been stored in the realized recycling storage apparatus <NUM> exceeds the second threshold value. In these cases, it is possible to determine whether a banknote is excluded from dispensing objects for each denomination corresponding to each recycling storage apparatus <NUM>, and it is possible to suppress a decrease in the dispensing efficiency for each denomination.

Next, a configuration of a banknote processing apparatus in Embodiment <NUM> of the present disclosure will be described. <FIG> is a block diagram illustrating an overview of an internal configuration of the banknote processing apparatus. <FIG> is a schematic diagram illustrating a configuration of a serial number list. Note that, a banknote processing apparatus 1B in Embodiment <NUM> is an example of the banknote processing apparatus <NUM> of Embodiment <NUM>. The same configurations as those of the banknote processing apparatus <NUM> of Embodiment <NUM> or the banknote processing apparatus 1A of Embodiment <NUM> will be denoted by the same reference signs, and descriptions thereof will be simplified or omitted.

The banknote processing apparatus 1B of Embodiment <NUM> illustrated in <FIG> and the banknote processing apparatus 1A of Embodiment <NUM> differ in that the banknote processing apparatus 1B further comprises a depositing unit <NUM>, in that the banknote processing apparatus 1B comprises a transport unit 4B instead of the transport unit <NUM>, in the content of the list stored in the memory unit <NUM>, and in the processing content of the control unit <NUM>.

The depositing unit <NUM> is an example of an inlet section into which a banknote is inserted. The depositing unit <NUM> is a portion into which a banknote is inserted when depositing processing of a banknote is performed, for example. The depositing unit <NUM> is configured so as to be capable of stacking a plurality of banknotes in an overlapping state. The depositing unit <NUM> comprises an inlet <NUM>, and a feeding mechanism (not illustrated). In the front portion of the housing <NUM> and rearward from the outlet <NUM>, the inlet <NUM> is provided to open upward. The feeding mechanism takes in (receives) a plurality of banknotes stacked in the depositing unit <NUM> one by one into the housing <NUM>.

The transport unit 4B comprises the first transport path <NUM> to the fourth transport path <NUM> and a fifth transport path <NUM>.

The fifth transport path <NUM> connects the depositing unit <NUM> and a position of the upper-side path <NUM>, where the position is on the rear side of a connection part between the upper-side path <NUM> and the second transport path <NUM> and is on the front side of the recognition unit <NUM>. The fifth transport path <NUM> is provided so as to extend from the upper-side path <NUM> frontward and obliquely upward (in a third direction), that is, so as to extend in a direction different from the direction in which the rear reversing path <NUM> extends. A connection part between the fifth transport path <NUM> and the upper-side path <NUM> is provided with a fourth diverter mechanism. In the same manner as in the first transport path <NUM> to the fourth transport path <NUM>, the fifth transport path <NUM> is formed of a combination of a roller, a belt, a motor, a sidewall, and the like. A tracking sensor(s) that detect(s) the passage of a banknote is/are provided at a predetermined position(s) of the fifth transport path <NUM>. The control unit <NUM> detects the position of a banknote based on detection signals from the tracking sensors, and controls the first diverter mechanism to the fourth diverter mechanism, thereby transporting the banknote to a predetermined configuration.

The memory unit <NUM> stores a serial number list 241B as illustrated in <FIG> and the abnormal note list 141A illustrated in <FIG>.

The serial number list 241B is a list of banknotes recognized as normal by the recognition unit <NUM> when the depositing processing is performed. The memory unit <NUM> stores the serial number lists 241B of the respective recycling storage apparatuses <NUM> forming the first storage unit <NUM>. That is, in Embodiment <NUM>, the memory unit <NUM> stores the serial number list 241B of the first recycling storage apparatus 21A and the serial number list 241B of the second recycling storage apparatus 21B. The serial number list 241B comprises banknote information 242B corresponding to each banknote. For example, when one banknote is stored in the first recycling storage apparatus 21A, the control unit <NUM> adds the banknote information 242B corresponding to the banknote to the serial number list 241B of the first recycling storage apparatus 21A. For example, when one banknote is fed out from the first recycling storage apparatus 21A, the control unit <NUM> deletes the banknote information 242B corresponding to the banknote from the serial number list 241B of the first recycling storage apparatus 21A. The banknote information 242B comprises storage order information 243B and serial number information 244B.

The storage order information 243B indicates the order of storage of banknotes in the recycling storage apparatus <NUM>. The serial number information 244B indicates the serial numbers of banknotes.

Note that, one serial number list 241B may comprises the banknote information 242B of the respective recycling storage apparatuses <NUM> forming the first storage unit <NUM>. In this case, the banknote information 242B preferably comprises storage destination information indicating the recycling storage apparatus <NUM> (the first recycling storage apparatus 21A or the second recycling storage apparatus 21B) in which a banknote is stored.

Abnormality factors indicated by the abnormality factor information <NUM> of Embodiment <NUM> comprise "serial number-disagreement" that is one abnormality factor of a serial number. A case where an abnormality factor indicated by the abnormality factor information <NUM> is "serial number-disagreement" indicates that a serial number of a banknote recognized by the recognition unit <NUM> in the first recognition processing when the discharging processing is performed disagrees with a serial number of the serial number information 244B in the banknote information 242B corresponding to the banknote.

Next, operations of the banknote processing apparatus 1B will be described. In Embodiment <NUM>, depositing processing is performed in addition to the dispensing processing as an example of the discharging processing, the first storage processing, and the second storage processing that are performed in Embodiment <NUM>. Regarding the dispensing processing, the first storage processing, and the second storage processing, only differences thereof between Embodiment <NUM> and Embodiments <NUM> and <NUM> will be described.

First, the depositing processing will be described. When the control unit <NUM> realizes a banknote depositing instruction by an operator based on an operation signal from the operation unit, the control unit <NUM> controls the feeding mechanism of the depositing unit <NUM> such that one banknote is fed out from the depositing unit <NUM>.

The control unit <NUM> controls the transport unit 4B such that the banknote is transported to the recognition unit <NUM> via the fifth transport path <NUM> and the upper-side path <NUM>, and the recognition unit <NUM> performs third recognition processing. The content of the third recognition processing is the same as those of the first recognition processing and the second recognition processing. The direction in which the banknote passes through the recognition unit <NUM> varies between the first recognition processing and the third recognition processing. The control unit <NUM> determines whether the banknote recognized in the third recognition processing is normal.

In a case where it has been determined that the banknote is a normal note, the control unit <NUM> controls the transport unit 4B and the first storage unit 2A such that the banknote is stored in the first storage unit 2A (the first recycling storage apparatus 21A or the second recycling storage apparatus 21B) corresponding to the banknote. For example, the control unit <NUM> causes the banknote to pass through at least the upper-side path <NUM>, the rear reversing path <NUM> and the lower-side path <NUM> and to be stored in the first recycling storage apparatus 21A. The control unit <NUM> adds the banknote information 242B of the banknote recognized as normal based on a result of the third recognition processing to the serial number list 241B.

In a case where it has been determined in the third recognition processing that the banknote is an abnormal note, on the other hand, the control unit <NUM> controls the transport unit 4B such that the banknote is dispensed from the dispensing unit <NUM>.

The control unit <NUM> repeats the processing to cause a banknote to be stored in the first storage unit 2A or the second storage unit <NUM> based on a result of the third recognition processing until there is no banknote in the depositing unit <NUM>. Note that, the control unit <NUM> may cause a banknote determined as normal in the third recognition processing to be stored in the temporary storage unit <NUM>. After there is no banknote in the depositing unit <NUM> and a depositing amount is accepted, the control unit <NUM> causes a banknote stored in the temporary storage unit <NUM> to be stored in the first storage unit 2A (the first recycling storage apparatus 21A or the second recycling storage apparatus 21B) corresponding to the banknote.

Next, the dispensing processing will be described. The dispensing processing of Embodiment <NUM> and the dispensing processing of Embodiments <NUM> and <NUM> are common except the following three points:.

Here, a matter deemed to be a factor in causing an abnormality of "serial number-disagreement" will be described. When the third recognition processing is performed, a banknote is transported from the depositing unit <NUM> to the recognition unit <NUM> via the fifth transport path <NUM> and the upper-side path <NUM>. Since the direction in which the fifth transport path <NUM> extends differs from the direction in which the upper-side path <NUM> extends, the banknote warps when transported from the fifth transport path <NUM> to the upper-side path <NUM>. At this time, the banknote warps in the opposite direction to the direction when the first recognition processing is performed. That is, the direction in which the banknote warps when transported from the fifth transport path <NUM> extending in the third direction to the upper-side path <NUM> extending in the first direction differs from the direction in which the banknote warps when transported from the rear reversing path <NUM> extending in the second direction to the upper-side path <NUM> extending in the first direction. Thus, in a case where the warpage direction of a banknote varies between when the first recognition processing is performed and when the third recognition processing is performed, the distance from the position of the serial number to the recognition unit <NUM> also varies. Consequently, a recognition result of a serial number may vary between the first recognition processing and the third recognition processing.

Note that, the control unit <NUM> may also determine that an abnormality of "serial number-disagreement" does not occur in a case where a serial number of a banknote recognized in the first recognition processing disagrees with a serial number in the banknote information 242B corresponding to the banknote by a number of digits that is equal to or less than a number of digits set in advance. Even in a case where a serial number of a banknote recognized in the first recognition processing disagrees with a serial number in the banknote information 242B corresponding to the banknote, the control unit <NUM> may determine that an abnormality of "serial number-disagreement" does not occur when the serial number of the banknote recognized in the first recognition processing agrees with a serial number in the banknote information 242B corresponding to another banknote. Although the dispensing processing has been described thus far as an example of the discharging processing, the banknote movement is the same in the case of collection processing. For example, operations of the collection processing can be understood by replacing the dispensing amount described above with a collection amount or a number of collected banknotes.

Next, the first storage processing and the second storage processing will be described. The first storage processing of Embodiment <NUM> and the first storage processing of Embodiments <NUM> and <NUM> are common except a difference <NUM>-<NUM> described below. Further, the second storage processing of Embodiment <NUM> and the second storage processing of Embodiments <NUM> and <NUM> are common except differences <NUM>-<NUM> and <NUM>-<NUM> described below.

The difference <NUM>-<NUM> will be described. In the condition determination processing in step S12, the control unit <NUM> determines whether the condition <NUM>-<NUM> described above or a condition <NUM>-<NUM> described below is satisfied.

The condition <NUM>-<NUM> is a condition related to a factor in causing a banknote to be recognized as abnormal in the first recognition processing. The condition <NUM>-<NUM> is a condition that a factor in causing a banknote to be recognized as abnormal is an abnormality of a serial number ("serial number-unreadable" or "serial number-disagreement"). In a case where an abnormality of a banknote is "serial number-unreadable" or "serial number-disagreement", the control unit <NUM> determines that the storage object banknote is a banknote for which the predetermined condition is satisfied. In a case where an abnormality of a banknote is an abnormality other than "serial number-unreadable" and "serial number-disagreement", the control unit <NUM> determines that the storage object banknote is a banknote for which the predetermined condition is not satisfied.

Embodiment <NUM> described above exhibits the same working effects as those exhibited by Embodiments <NUM> and <NUM>.

Tracking sensors that detect the passage of a banknote are provided at predetermined positions of the first transport path <NUM> to the sixth transport path <NUM> and the seventh transport path <NUM> to the eleventh transport path <NUM>. The control unit <NUM> detects the position of a banknote based on detection signals from the tracking sensors, and controls the first diverter mechanism and the eighth diverter mechanisms, thereby transporting the banknote to a predetermined configuration.

The memory unit <NUM> stores the serial number list 241B as illustrated in <FIG> and the abnormal note list 141A illustrated in <FIG>.

Next, operations of the banknote processing apparatus 1C will be described. In Embodiment <NUM>, depositing processing, dispensing processing as an example of the discharging processing, first storage processing, and second storage processing that are the same as those in Embodiment <NUM> are performed. Here, descriptions will be given mainly of differences of each processing between Embodiments <NUM> and <NUM>.

First, the depositing processing will be described. When the control unit <NUM> realizes a banknote depositing instruction by an operator, the control unit <NUM> causes one banknote stacked in the depositing unit <NUM> to be transported to the recognition unit <NUM> via the third transport path <NUM> and the upper-side path <NUM>, and the recognition unit <NUM> performs the third recognition processing.

The control unit <NUM> causes the banknote determined as a normal note based on a result of the third recognition processing to pass through at least the upper-side path <NUM>, the rear reversing path <NUM>, the lower-side path <NUM>, the sixth transport path <NUM>, and the eighth transport path <NUM> and to be stored in the recycling storage apparatus <NUM> (one of the first recycling storage apparatus 21A to the fourth recycling storage apparatus 21D (the first storage unit 2C)) corresponding to the banknote. The control unit <NUM> adds the banknote information 242B of the banknote recognized as normal based on the result of the third recognition processing to the serial number list 241B.

The control unit <NUM>, on the other hand, causes the banknote determined as abnormal based on a result of the third recognition processing to pass through the upper-side path <NUM>, the rear reversing path <NUM>, the lower-side path <NUM>, the front reversing path <NUM>, and the second transport path <NUM>, and to be dispensed from the dispensing unit <NUM>. The control unit <NUM> repeats the processing to cause a banknote to be stored in the first storage unit 2C or the second storage unit <NUM> based on a result of the third recognition processing until there is no banknote in the depositing unit <NUM>. Note that, the control unit <NUM> may cause a banknote determined as normal in the third recognition processing to be stored in the temporary storage unit <NUM>. After there is no banknote in the depositing unit <NUM> and a depositing amount is accepted, the control unit <NUM> causes a banknote stored in the temporary storage unit <NUM> to be stored in the recycling storage apparatus <NUM> (one of the first recycling storage apparatus 21A to the fourth recycling storage apparatus 21D (the first storage unit 2C)) corresponding to the banknote.

Next, the dispensing processing will be described. The control unit <NUM> performs the processing in steps S1 to S8 illustrated in <FIG>. In step S2, the control unit <NUM> causes a banknote to be fed out from the recycling storage apparatus <NUM> (one of the first recycling storage apparatus 21A to the fourth recycling storage apparatus 21D (the first storage unit 2C)) corresponding to the banknote to be dispensed. In step S3, the control unit <NUM> causes the banknote to be transported to the recognition unit <NUM> via at least the eighth transport path <NUM>, the sixth transport path <NUM>, the lower-side path <NUM>, the rear reversing path <NUM>, and the upper-side path <NUM>, and causes the recognition unit <NUM> to perform the first recognition processing (step S3).

In step S5, the control unit <NUM> causes the banknote recognized as normal in the first recognition processing to pass through the upper-side path <NUM>, the front reversing path <NUM>, and the second transport path <NUM> and to be dispensed from the dispensing unit <NUM>. In step S7, the control unit <NUM> causes the banknote recognized as abnormal in the first recognition processing to pass through the upper-side path <NUM>, the front reversing path <NUM>, and the fourth transport path <NUM> and to be stored in the temporary storage unit <NUM>.

Next, the storage processing will be described. The control unit <NUM> performs the processing in steps S11 to S20 illustrated in <FIG> as the first storage processing or the second storage processing.

In the first storage processing, the control unit <NUM> determines in the condition determination processing in step S12 whether the conditions <NUM>-<NUM> and <NUM>-<NUM> are satisfied. The control unit <NUM> may determine only condition <NUM>-<NUM> or both the conditions.

The condition <NUM>-<NUM> is a condition related to a number of banknotes stored in the first storage unit 2C. For example, the condition <NUM>-<NUM> is a condition that the number of banknotes stored in the recycling storage apparatus <NUM> in which a storage object banknote has been stored is equal to or less than the first threshold value at the time when the dispensing processing ends.

The control unit <NUM> realizes the recycling storage apparatus <NUM> (one of the first recycling storage apparatus 21A to the fourth recycling storage apparatus 21D (the first storage unit 2C)) in which the storage object banknote has been stored, the control unit <NUM> determines that the predetermined condition is satisfied when the number of banknotes stored in the realized recycling storage apparatus <NUM> at the time when the dispensing processing ends is equal to or less than the first threshold value, and the control unit <NUM> determines that the predetermined condition is not satisfied when the number of banknotes stored in the realized recycling storage apparatus <NUM> at the time when the dispensing processing ends exceeds the first threshold value.

The condition <NUM>-<NUM> is a condition related to the number of banknotes stored in the temporary storage unit <NUM>. For example, the condition <NUM>-<NUM> is a condition that, of banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends, the total number of banknotes having been stored in the recycling storage apparatus <NUM> that is the same recycling storage apparatus <NUM> in which a storage object banknote has been stored is equal to or less than the second threshold value.

The control unit <NUM> realizes the recycling storage apparatus <NUM> (one of the first recycling storage apparatus 21A to the fourth recycling storage apparatus 21D (the first storage unit 2C)) in which the storage object banknote has been stored, the control unit <NUM> determines that the predetermined condition is satisfied when, of banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends, the total number of banknotes having been stored in the realized recycling storage apparatus <NUM> is equal to or less than the second threshold value, and the control unit <NUM> determines that the predetermined condition is not satisfied when, of the banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing ends, the total number of banknotes having been stored in the realized recycling storage apparatus <NUM> exceeds the second threshold value.

In the first storage processing, in a case where it has been determined in step S18 that a banknote remains in the temporary storage unit <NUM>, the control unit <NUM> performs the processing in step S12.

In the first storage processing and the second storage processing, in step S15, the control unit <NUM> causes the banknote to be transported to the recognition unit <NUM> via the fourth transport path <NUM>, the front reversing path <NUM>, and the upper-side path <NUM>, and causes the recognition unit <NUM> to perform the second recognition processing. In step S17, the control unit <NUM> causes a banknote in a case where it has been determined that the predetermined condition is satisfied or a banknote recognized as abnormal in the second recognition processing to pass through the upper-side path <NUM>, the rear reversing path <NUM>, the lower-side path <NUM>, the front reversing path <NUM>, and the fourth transport path <NUM> and to be stored in the temporary storage unit <NUM>. In step S20, the control unit <NUM> causes the banknote recognized as abnormal in the second recognition processing to pass through at least the upper-side path <NUM>, the rear reversing path <NUM>, the lower-side path <NUM>, the sixth transport path <NUM>, and the eighth transport path <NUM> and to be stored in the recycling storage apparatus <NUM> (one of the first recycling storage apparatus 21A to the fourth recycling storage apparatus 21D (the first storage unit 2C)) corresponding to banknote.

Embodiment <NUM> described above exhibits the same working effects as those exhibited by Embodiments <NUM> to <NUM>.

Variations not falling under the scope of the invention:.

The storage processing in Embodiments <NUM> to <NUM> may also be performed based on a flowchart illustrated in <FIG>. After the processing in steps S11 to S14, the control unit <NUM> determines whether it has been determined in the condition determination processing that the predetermined condition is satisfied (step S16). In a case where it has been determined that the predetermined condition is not satisfied (step S16: NO), the control unit <NUM> causes a banknote to be transported to the recognition unit <NUM> and causes the recognition unit <NUM> to perform the second recognition processing (step S15). In step S19 subsequent thereto, the control unit <NUM> causes a banknote, whose result of the second recognition processing has been determined as normal, to be stored in the first storage unit <NUM>, 2A or 2C (step S20). The control unit <NUM> causes a banknote, whose result of the second recognition processing has been determined as abnormal in step S19, to be stored in the second storage unit <NUM> (step S17), and performs the processing in step S18.

In a case where it has been determined that the predetermined condition is satisfied (step S16: YES), the control unit <NUM> does not perform the second recognition processing on the banknote, but causes the banknote to be stored in the second storage unit <NUM> (step S17). Here, since it has been determined that the predetermined condition is satisfied, the following two transport routes of the banknote are conceivable in a case where the second recognition processing is not performed but the banknote is stored in the second storage unit <NUM>.

A first transport route is a route that causes a banknote to pass through the recognition unit <NUM> in the same manner as in a case where it has been determined that the predetermined condition is not satisfied. In this case, when the banknote passes through the recognition unit <NUM> after it has been determined that the predetermined condition is not satisfied, the control unit <NUM> does not allow the recognition unit <NUM> to perform the second recognition processing.

A second transport route is a route that does not allow a banknote to pass through the recognition unit <NUM>. For example, in the banknote processing apparatus 1C of Embodiment <NUM>, the control unit <NUM> causes a banknote to pass through the second transport route formed of the fourth transport path <NUM>, the front reversing path <NUM>, the fifth transport path <NUM>, and the seventh transport path <NUM> and to be stored in the second storage unit <NUM> as indicated by an arrow R2. Further, in the banknote processing apparatuses <NUM>, 1A and 1B of Embodiments <NUM> to <NUM>, a front reversing path <NUM> as indicated by a two-dot chain line in <FIG> and <FIG> may be further provided, and the control unit <NUM> may cause a banknote to pass through the second transport route formed of the upper-side path <NUM>, the front reversing path <NUM>, and the lower-side path <NUM> and to be stored in the second storage unit <NUM> as indicated by the arrow R2.

In Embodiments <NUM> to <NUM>, dispensing processing illustrated in <FIG> and storage processing illustrated in <FIG> may also be performed.

First, the dispensing processing will be described. As illustrated in <FIG>, the control unit <NUM> performs the processing in steps S1 to S4. The control unit <NUM> causes a banknote determined as normal in step S4 to be dispensed from the dispensing unit <NUM> (step S5), and performs the processing in step S6. The processing up to this point is the same as the dispensing processing of Embodiments <NUM> to <NUM>.

The control unit <NUM> performs the condition determination processing on a banknote determined as abnormal in step S4 (step S31).

In the condition determination processing, the control unit <NUM> determines whether a predetermined condition is satisfied. As the predetermined condition, it is possible to exemplify a condition <NUM>-<NUM> and a condition <NUM>-<NUM> described below. In the condition determination processing, the control unit <NUM> may determine only one of the conditions <NUM>-<NUM> and <NUM>-<NUM> or both the conditions. In the condition determination processing, the control unit <NUM> may use both the conditions <NUM>-<NUM> and <NUM>-<NUM> as determination objects, determine that the predetermined condition is satisfied in a case where one of the conditions of the determination objects is satisfied, and determine that the predetermined condition is not satisfied in a case where all the conditions of the determination objects are not satisfied.

The condition <NUM>-<NUM> is a condition related to a number of banknotes stored in the first storage units <NUM>, 2A and 2C. For example, the condition <NUM>-<NUM> is a condition that the number of banknotes stored in the first storage units <NUM>, 2A and 2C at a time when the dispensing processing starts or immediately before a storage object banknote is fed out is equal to or less than the first threshold value. In a case where the number of banknotes stored in the first storage units <NUM>, 2A and 2C is equal to or less than the first threshold value, the control unit <NUM> determines that the predetermined condition is satisfied. In a case where the number of banknotes stored in the first storage units <NUM>, 2A and 2C exceeds the first threshold value, the control unit <NUM> determines that the predetermined condition is not satisfied.

Here, in a case where the banknote processing apparatus <NUM> of Embodiment <NUM> is used, the condition <NUM>-<NUM> is a condition that a number of banknotes stored in one recycling storage apparatus <NUM> is equal to or less than the first threshold value. When the banknote processing apparatuses 1A, 1B and 1C of Embodiments <NUM> to <NUM> are used, the condition <NUM>-<NUM> may be a condition that, of a plurality of recycling storage apparatuses <NUM>, a number of banknotes stored in the recycling storage apparatus <NUM> in which a storage object banknote has been stored is equal to or less than the first threshold value, or may be a condition that a total number of banknotes in the plurality of recycling storage apparatuses <NUM> is equal to or less than the first threshold value.

The condition <NUM>-<NUM> is a condition related to a factor in causing a banknote to be recognized as abnormal in the first recognition processing. For example, the condition <NUM>-<NUM> is a condition that the factor in causing a banknote to be recognized as abnormal is an abnormality of a serial number. In a case where an abnormality of a banknote is an abnormality of a serial number, the control unit <NUM> determines that the storage object banknote is a banknote for which the predetermined condition is satisfied. In a case where an abnormality of a banknote is an abnormality other than an abnormality of a serial number, the control unit <NUM> determines that the storage object banknote is a banknote for which the predetermined condition is not satisfied.

Here, in a case where the banknote processing apparatus <NUM> of Embodiment <NUM> is used, an abnormality of a serial number in the condition <NUM>-<NUM> is "serial number-unreadable". In a case where the banknote processing apparatuses 1A, 1B and 1C according to Embodiments <NUM> to <NUM> are used, an abnormality of a serial number in the condition <NUM>-<NUM> is "serial number-unreadable" or "serial number-disagreement".

After the processing in step S31, the control unit <NUM> determines whether it has been determined that the predetermined condition is satisfied for a banknote (step S32). In a case where it has been determined that the predetermined condition is satisfied for the banknote (step S32: YES), the control unit <NUM> causes the banknote to be stored in the second storage unit <NUM> (step S33), and performs the processing in step S2.

In a case where it has been determined that the predetermined condition is not satisfied for the banknote (step S32: NO), the control unit <NUM> causes the banknote to be stored in the temporary storage unit <NUM> (step S7). The control unit <NUM> adds the abnormal note information <NUM> of the banknote recognized as abnormal to the abnormal note list <NUM> (step S8), and performs the processing in step S2.

Next, the storage processing will be described. As illustrated in <FIG>, the control unit <NUM> performs the processing in step S11. In a case where it has been determined that no banknote is stored in the temporary storage unit <NUM> (step S <NUM>: NO), the control unit <NUM> ends the storage processing. In a case where it has been determined that a banknote is stored in the temporary storage unit <NUM> (step S11: YES), the control unit <NUM> performs the processing in steps S13 to S15 in the same manner as in the storage processing of Embodiments <NUM> to <NUM>.

After the processing in step S15 (the second recognition processing), the control unit <NUM> determines whether a result of the second recognition processing is normal (step S19). In a case where it has been determined that the result of the second recognition processing is normal (step S19: YES), the control unit <NUM> causes the banknote to be stored in the first storage unit <NUM>, 2A or 2C (the recycling storage apparatus <NUM> corresponding to the banknote) (step S20), and performs the processing in step S18. In a case where it has been determined that the result of the second recognition processing is abnormal (step S19: NO), the control unit <NUM> causes the banknote to be stored in the second storage unit <NUM> (step S17), and performs the processing in step S18.

Even in Variation <NUM> described above, it is possible to suppress a decrease in the dispensing efficiency in the same manner as in Embodiments <NUM> to <NUM>.

In Embodiments <NUM> to <NUM> and Variations <NUM> and <NUM>, the conditions <NUM>-<NUM> and <NUM>-<NUM> related to a factor in causing a banknote to be recognized as abnormal in the first recognition processing may be an abnormality other than an abnormality of a serial number, for example, tearing, soiling, and perforation of a banknote.

In Embodiments <NUM> to <NUM> and Variation <NUM>, a condition that a total number of banknotes stored in all recycling storage apparatuses <NUM> forming the first storage unit 2A or 2C at a time when the dispensing processing or the collection processing ends is equal to or less than the first threshold value may be applied as the condition <NUM>-<NUM>. Further, a condition that the number of banknotes stored in the temporary storage unit <NUM> at the time when the dispensing processing or the collection processing ends is equal to or less than the second threshold value may be applied as the condition <NUM>-<NUM>. In these cases, in a case where it has been determined in step S18 that a banknote remains in the temporary storage unit <NUM>, the processing in step S13 is preferably performed as indicated by a solid line in <FIG>.

As sheets to be processed with the sheet processing apparatus of the present disclosure, coupons and checks may also be applied.
