Description

  The present invention relates to a banknote processing apparatus and a banknote processing method for identifying a denomination of banknotes based on image data of banknotes.

  DESCRIPTION OF RELATED ART The banknote processing apparatus which can perform both deposit / withdrawal of the banknote of a rose and the deposit / withdrawal of the banknote bundle bundled by the binding band is known conventionally. For example, Patent Literature 1 includes a rose banknote processing unit that handles deposits and withdrawals of rose banknotes and a bundled banknote processing unit that handles withdrawals of banknote bundles, and the rose banknote processing unit includes rose banknotes that are inserted into a deposit port. The identification unit identifies the denomination and stores it in the denomination banknote storage unit according to the identified denomination, and the banknote stored in the banknote storage unit identifies the denomination in another identification unit. The banknote identified as a denomination corresponding to the denomination-type banknote storage part is dispensed as a withdrawal banknote to the withdrawal port, and the bundle banknote processing part receives another banknote bundle transported from the bundle storage part. Discloses a technique for identifying a denomination of a banknote bundle and paying out a banknote bundle identified as a denomination corresponding to the bundle storage unit as a withdrawal banknote bundle to a bundle outlet. Unlike a rose banknote, the banknote bundle is bound by a binding band, and the image of the banknote bundle acquired by the identification unit includes the binding band. Therefore, in order to ensure the accuracy of the identification process, the banknote bundle The distinction process of roses and the distinction process of rose banknotes are different processes depending on the presence or absence of a binding band.

  Moreover, in the banknote denomination and authenticity identification process, the technique which performs the banknote denomination and authenticity identification based on the image data of a part of banknote is known. For example, Patent Literature 2 specifies in advance a feature region that is a region in which a denomination and a feature of a bill that is a true / false identification target appear, and the standard pattern of the feature region and the bill of judgment target A technique for discriminating the denomination and authenticity of a bill by comparing it with image data of a characteristic region is disclosed.

  Thus, by applying the technique disclosed in Patent Document 1, it is possible to perform both processing of depositing / withdrawing and scrutinizing rose banknotes and withdrawal and scrutiny of banknote bundles bound in a binding band. An apparatus can be provided. Moreover, by applying the technique disclosed in Patent Document 2, the amount of information of the standard pattern for the genuine note held for each denomination, direction, and banknote classification (rose banknote or bundle banknote) is suppressed. Can do it.

  Below, with reference to an accompanying drawing, a suitable example of a bill processing device and bill processing method used for denomination identification of a rose bill and a bundle bill concerning the present invention is described in detail.

  First, the outline | summary of the identification process of the common money type in the rose banknote and banknote bundle which concerns on this invention is demonstrated using FIG.

  The outline | summary of the discrimination process of the money type of a rose banknote is demonstrated using the upper half of FIG. Acquired image data of rose banknotes for denomination identification, and the entire area of acquired image data and the entire area of reference image data generated by statistically processing image data of genuine banknotes prepared in advance The evaluation value for the entire area is calculated based on the threshold value data when evaluating the entire area prepared in advance for loose banknotes, and the degree of coincidence between the image data of the rose banknotes to be identified and the reference image data is high In this case, the denomination of the rose banknote to be identified is identified as the denomination of the reference image data.

  Next, the outline | summary of the identification processing of the money type of a banknote bundle is demonstrated using the lower half of FIG. The image data of the banknote bundle of the denomination identification target is acquired. In the case of banknote bundles, as shown in FIG. 1, since the image corresponding to the binding band is included in the acquired image data, the entire area of the acquired image is compared with the reference image data in the same manner as the loose banknotes. If the denomination of the denomination is performed, it is highly likely that the denomination of the denomination is not correctly performed due to the influence of the binding band included in the image data.

  Therefore, when identifying the denomination of the banknote bundle, the entire area of the image data acquired as shown in FIG. 1 is divided into the area 1 and the area 2, and the image data acquired for each area. And by calculating the evaluation value for each area based on the reference image data and comparing the threshold value data when evaluating the area 1 prepared in advance for the banknote bundle or the threshold data when evaluating the area 2 The denomination is identified for each area.

  In the example shown in FIG. 1, since the binding band is reflected in the area 1 of the banknote bundle image data, the identification of the denomination of the banknote bundle by the area 1 may be determined not to match the reference image data. However, since the binding band is not reflected in the area 2 of the banknote bundle image data, the binding band does not affect the denomination of the banknote bundle based on the area 2. The denomination of the banknote bundle is divided into areas 1 and 2, and the denomination is identified for each area. If the degree of coincidence with the reference image data is high in any area, the identification target is identified. The denomination of the rose bill is identified as the denomination of the reference image data.

  Further, as shown in FIG. 1, the same reference image data can be used for identifying the denomination of the rose banknote and identifying the denomination of the banknote bundle. The reference image data is generated by acquiring image data of a plurality of genuine banknotes and statistically processing the acquired plurality of image data. It is also possible to generate threshold data for the whole area for rose banknotes and threshold data for each area for banknote bundles by statistically processing the image data of a plurality of genuine banknotes acquired at the time of generating the reference image data. is there.

  Moreover, since the contents of the denomination identification process for each area are different only in the size of the area and the logical process contents are the same, the program corresponding to the denomination identification process for loose banknotes And a program corresponding to the denomination identification process of the banknote bundle can be made common.

  Thus, based on the image data of genuine banknotes, the common reference image data to be compared with the image data of rose banknotes or the image data of banknote bundles in the identification processing of denominations of rose banknotes and banknote bundles, Since the threshold value data related to the denomination identification and the threshold data related to the denomination identification of the banknote bundle are generated together, it is possible to share the contents of the identification processing of the rose banknote and the banknote bundle. It is possible to reduce time and effort required for development of processing related to identification of denominations of rose banknotes and identification of denominations of bundles of banknotes and preparation of information necessary for the processing.

Except for those sent to the withdrawal reject box 77, the loose banknotes S that have passed through the withdrawal identification unit 96 are accumulated in the stackers 76a and 76b. The bundles B ′ of loose banknotes accumulated in the stackers 76 a and 76 b are transported to the bundle banknote processing unit 101 by the bundle transport unit 6.

  Then, the bundle B ′ of loose banknotes conveyed to the bundled bill processing unit 101 shown in FIG. 3 is sent out to the bundle lifting / lowering passage 2 as the bundle of bills B in the same manner as in the case of the local binding process. After the elevating stage 20 is lowered to the lower position h3 and the shutter of the bundle discharge port 13 is opened, the inclined plate 22 on the elevating stage 20 is inclined forward and downward so that the banknote bundle B is discharged from the bundle discharge port 13. The

  Next, the rose banknotes S stored in the banknote storage unit 8 of the rose banknote processing unit 102 are bundled in the bundled banknote processing unit 101 and can be taken out from the bundle deposit / withdrawal port 10 as a banknote bundle B. The bundled withdrawal process will be described.

  First, in the loose banknote processing unit 102 shown in FIG. 4, the loose banknotes S stored in any of the banknote storages 8a to 8e are accumulated in the stackers 76a and 76b in the same manner as in the case of the bundle collecting process. , A bundle B ′ of rose bills is conveyed to the bundle bill processing unit 101 by the bundle conveyance unit 6.

  Then, the bundle B ′ of loose banknotes conveyed to the bundled banknote processing unit 101 shown in FIG. 3 is sent out to the bundle elevating passage 2 as the bundle of banknotes B in the same manner as in the case of the above-described local binding process, 10 is ready to be taken out.

  Next, the bundling and loading process in which the bulk banknotes S inserted into the deposit stacking unit 70 of the bulk banknote processing unit 102 are bundled in the bundled banknote processing unit 101 and stored as the banknote bundle B in the bundle storage unit 3 will be described.

  First, in the banknote processing unit 102 shown in FIG. 4, the banknotes S thrown into the deposit stacking unit 70 are stacked on the stackers 76a and 76b, and the banknote processing unit 101 uses the bundle transport unit 6 as a bundle B 'of rose banknotes. It is conveyed to. Then, the bundle B ′ of loose banknotes conveyed to the bundled banknote processing unit 101 shown in FIG. 3 is sent out to the bundle lifting / lowering passage 2 as the bundle of banknotes B through the binding printing unit 5.

  After the banknote bundle B sent out to the bundle elevating passage 2 is placed on the elevating stage 20 waiting at the receiving position h1, the elevating stage 20 is lowered to the height of the transport path. At this time, the opening / closing plate 34 of the bundle lifting / lowering passage 2 is opened. Further, the swing-retreat portion 4 a of the transport unit 4 that has been retracted in preparation for the passage of the lift stage 20 swings to the transport position and advances into the bundle lift passage 2. And the banknote bundle B is conveyed to the bundle storage part 3 side along a conveyance path by driving the conveyance belt 44 of the conveyance part 4. At this time, the identification unit 43 identifies the denomination and the like of the banknote bundle B.

  When the banknote bundle B reaches the opening / closing plate 34 corresponding to the bundle storages 3a-3e to be stored, the conveyor belt 44 is stopped and the opening / closing plate 34 is opened, and the banknote bundle B is placed in the bundle storages 3a-3e. Stored.

  Next, an explanation will be given of an automatic collection process in which, when the rose banknotes S in the banknote storage unit 8 of the rose banknote processing unit 102 are full, they are automatically bundled in the bundle banknote processing unit 101 and stored in the bundle storage unit 3 as a banknote bundle B. To do.

  First, in the loose banknote processing unit 102 shown in FIG. 4, the full banknotes S of the banknote storages 8a to 8e are accumulated in the stackers 76a and 76b in the same manner as in the case of the bundle collecting process. The bundle B ′ is conveyed to the bundle bill processing unit 101 by the bundle conveyance unit 6.

  Then, the bundle B ′ of the banknotes conveyed to the bundled bill processing unit 101 shown in FIG. 3 is sent to the bundle lifting / lowering passage 2 as the bundle of bills B in the same manner as in the case of the bundle loading process, and then corresponds. It is stored in the bundle storages 3a to 3e.

  Next, the internal configuration of the loose banknote processing unit 102 shown in FIG. 2 will be described. FIG. 5 is a block diagram showing an internal configuration of the loose banknote processing unit 102. As shown in FIG. 5, the loose banknote processing unit 102 includes a depositing port 16, a dispensing port 18, a depositing / dispensing unit 7, a bill storage unit 8, a transport unit 9, a storage unit 107, and a control unit 108.

  The storage unit 107 is a storage device including a hard disk device, a nonvolatile memory, and the like. The storage unit 107 includes identification reference data 107a, identification threshold data 107b, identification target banknote data 107c, and bundle identification threshold data 107d.

  The identification reference data 107a is data used when a denomination is identified, and is reference image data for each denomination and direction generated based on genuine ticket image data. The identification reference data 107a is information common to the bundled bill processing unit 101. The identification threshold value data 107b is data including a method for calculating an evaluation value calculated based on the image data of the rose banknote to be identified and the identification reference data 107a, a threshold value for identifying the denomination based on the evaluation value, and the like. is there. The identification target banknote data 107c is image data of an identification target loose banknote. The bundle identification threshold data 107d is data including a method for calculating an evaluation value for a banknote bundle used in the bundle banknote processing unit 101, a threshold for identifying a denomination based on the evaluation value, and the like. The bundle identification threshold data 107d is data that is generated in advance when the identification bill data processing unit 102 generates the identification reference data 107a and the identification threshold value data 107b and is distributed to the bundle bill processing unit 101. Detailed structures of the identification reference data 107a, the identification threshold data 107b, the identification target banknote data 107c, and the bundle identification threshold data 107d will be described later.

  The control unit 108 is a control unit that controls the entire loose banknote processing unit 102, and includes a deposit processing unit 108a, a withdrawal processing unit 108b, a collection processing unit 108c, a binding processing unit 108d, a withdrawal bill identifying unit 108e, and a learning process. Part 108f. Actually, a program corresponding to each functional unit is stored in a ROM or non-volatile memory (not shown), and this program is executed by a CPU (Central Processing Unit) to execute a process corresponding to each functional unit. I will let you.

  The deposit processing unit 108a identifies the denomination of the rose banknote inserted from the deposit port 16 by the deposit identifying unit 95, returns the banknote whose denomination could not be identified to the reject accumulating unit 71, The recognized banknotes are stored in the banknote storage unit 8 by denomination.

  If the withdrawal processing unit 108b receives an instruction to withdraw the loose banknote, the withdrawal processing unit 108b pays out the banknote for each denomination designated from the banknote storage unit 8 and pays out the loose banknote to the withdrawal port 18. Also, when the withdrawal processing unit 108b receives an instruction for bundle withdrawal, the withdrawal processing unit 108b feeds out the number of banknotes for each denomination specified from the banknote storage unit 8 and accumulates them in the stackers 76a and 76b. Unbundled banknote bundles accumulated in the stackers 76 a and 76 b are delivered to the bundled banknote processing unit 101 by the bundle transport unit 6. The bundled banknote processing unit 101 that has received the unbound banknote bundle and the bundle withdrawal instruction binds the accepted banknote bundle and pays out the bundled banknotes to the bundle deposit / withdrawal port 10.

  When the collection processing unit 108c receives an instruction for bundling collection, the collection processing unit 108c pays out banknotes for each denomination from the banknote storage unit 8 and accumulates them in the stackers 76a and 76b. Unbundled banknote bundles accumulated in the stackers 76 a and 76 b are delivered to the bundled banknote processing unit 101 by the bundle transport unit 6. The bundled banknote processing unit 101 that has received the unbound banknote bundle and the bundle collection instruction binds the accepted banknote bundle and collects the banknote bundle bound to the bundle discharge port 13. Further, when any of the banknote storages 8a to 8d detects full, the collection processing unit 108c feeds out the banknotes in the banknote storages 8a to 8d that are full and accumulates them in the stackers 76a and 76b. Unbundled banknote bundles accumulated in the stackers 76 a and 76 b are delivered to the bundled banknote processing unit 101 by the bundle transport unit 6. The bundled banknote processing unit 101 that has received an unbundled banknote bundle and an automatic collection instruction binds the received banknote bundle and stores it in the bundle storage unit 3.

  If the bundling processing unit 108d receives an instruction for local bundling and bundling loading, the denomination of the banknotes inserted from the deposit port 16 is identified by the deposit identifying unit 95, and the denomination cannot be specified. The banknotes are returned to the reject stacking unit 71, and banknotes whose denominations are specified are stacked on the stackers 76a and 76b. Unbundled banknote bundles accumulated in the stackers 76 a and 76 b are delivered to the bundled banknote processing unit 101 by the bundle transport unit 6. The bundled banknote processing unit 101 that has received an instruction for an unbound banknote bundle and a local bundle bundles the received banknote bundle and pays out the bundled banknote to the bundle deposit / withdrawal port 10. The bundled banknote processing unit 101 that has received an unbound banknote bundle and a bundle loading instruction binds the received banknote bundle and stores it in the bundle storage unit 3.

  The withdrawal bill identification unit 108e obtains image data of the bills fed out from the bill storage unit 8 shown in FIG. 4 and transported through the withdrawal transport path 92 by the withdrawal identification unit 96, and the identification target bill data 107c. To remember. Further, the denomination is identified based on the identification reference data 107a, the identification threshold data 107b, and the identification target banknote data 107c.

  The learning processing unit 108f acquires image data of a plurality of rose genuine bills for each denomination and direction in the rose banknote processing unit 102, and performs statistical processing based on the acquired plurality of denominations and image data for each direction. Then, identification reference data 107a, identification threshold data 107b, and bundle identification threshold data 107d are generated. The identification reference data 107 a is data that is commonly used by the loose banknote processing unit 102 and the bundled banknote processing unit 101, and the bundle identification threshold data 107 d is data that is used by the bundled banknote processing unit 101.

  Next, the configuration of the withdrawal identification unit 96 shown in FIG. 4 will be described with reference to FIG. As shown in FIG. 6, the withdrawal identification unit 96 includes a line sensor 96a, transport rollers 96b to 96j, and thickness detection rollers 96m and 96n.

  The line sensor 96a is a reflection type line sensor, and acquires image data of loose bills conveyed by the dispensing conveyance path 92. Further, the withdrawal identification unit 96 does not have a sensor for detecting the presence or absence of banknotes, and the line sensor 96a detects the presence or absence of banknotes. The line sensor 96a starts reading an image before the banknote reaches the line sensor 96a, and outputs image data that has already been read as image data of the banknote when the arrival of the banknote is detected. Further, the same line sensor 96 a used in the withdrawal identifying unit 96 is also used in the identifying unit 43 of the bundled bill processing unit 101.

  The transport rollers 96b to 96i transport bills at a predetermined speed. Moreover, the thickness detection rollers 96m and 96n detect the thickness of the banknote to be conveyed. The withdrawal identifying unit 96 adjusts the distance in the bill thickness direction between the transport rollers 96b to 96j facing the transport rollers 96b based on the detected thickness.

  Next, the concept of the identification reference data 107a, the identification threshold value data 107b, and the identification target banknote data 107c used in the denomination and direction identification process of the loose banknote processing unit 102 shown in FIG. 5 will be described with reference to FIG. .

  Fig.7 (a) is the figure which showed the example which divided | segmented the banknote surface in a present Example into several zones. In the present embodiment, the banknote surface is divided into 64 zones which can be divided into 16 in the x-axis direction and 4 in the y-axis direction. The mth zone (m = 0, 1, 2,..., f) in the x-axis direction and the nth zone (n = 0, 1, 2, 3) in the y-axis direction are represented as Zmn. The upper left zone of the banknote in the drawing is represented as Z00, and the lower right zone is represented as Z3f.

  FIG. 7B is a diagram showing an example of data for one direction of one denomination included in the identification reference data 107a for the zones divided in FIG. 7A. FIG. 7B shows data for one direction of one denomination included in the identification reference data 107a, which is data prepared in advance based on image data of rose genuine bills, This indicates that the reference value for the zone Zmn is bmn.

  FIG. 7C is a diagram illustrating an example of the identification target banknote data 107c for the zones divided in FIG. The identification target banknote data 107c is data obtained from the rose banknote to be identified by the withdrawal identification unit 96, and indicates that the value obtained for each zone Zmn is vmn.

  FIG. 7D is a diagram for explaining the concept of the identification threshold value data 107b. The identification threshold data 107b has an area and a determination threshold for each of the identification area 1 and the identification area 2. Each identification region is further divided into four sub-regions, and each sub-region has a sub-region start position, end position, and determination threshold value. In FIG. 7D, the determination threshold value of the sub-region where the start position of the identification area 1 is Z00 and the end position is Z07 is t01, the determination threshold value of the sub-area where the start position of the identification area 1 is Z10 and the end position is Z17. At t11, the determination threshold value of the sub-region where the start position of the identification region 1 is Z20 and the end position is Z27 is t21, the determination threshold value of the sub-region where the start position of the identification region 1 is Z30 and the end position is Z37 is t31 The determination threshold value of the sub-region where the start position of area 2 is Z08 and the end position is Z0f is t02, the determination threshold value of the sub-area where the start position of identification area 2 is Z18 and the end position is Z1f is t12, and the start of identification area 2 The determination threshold value of the sub-region having the position Z28 and the end position Z2f is t22, the determination threshold value of the identification region 2 is Z38, and the sub-region having the end position Z3f is t32.

  FIG. 7E shows a denomination identification method for a sub-region in which the start position of the identification area 1 is Z00 and the end position is Z07 for the rose banknote to be identified. When the evaluation value obtained by adding the absolute value of the difference between the value of the identification reference data 107a for each zone included in the sub area and the value of the recognition target banknote data 107c is equal to or less than the determination threshold t01 corresponding to the sub area For the sub-region, it is determined that the rose banknote to be identified is a rose banknote in the denomination / direction of the target identification reference data, and if the evaluation value exceeds the determination threshold t01, Regarding the area, it is determined that there is a possibility that the rose banknote to be identified is not the rose banknote in the denomination / direction of the target identification reference data.

  When it is determined that the determination results for each sub-region included in the identification area 1 are all the banknotes in the denomination / direction of the target identification reference data, the denomination of the denomination in the identification area 1 of the rose banknote to be identified The result is determined to be a loose banknote of the denomination / direction of the target identification reference data. If it is determined that there is a possibility that the determination result of any of the sub areas included in the identification area 1 is not a loose banknote of the denomination / direction of the target identification reference data, the denomination / direction of the identification area 1 It is determined that there is a possibility that the identification result is not a loose banknote of the denomination / direction of the target identification reference data.

  Similarly, for the identification area 2, the denomination / direction of the banknotes to be identified is identified, and the identification result for either the identification area 1 or the identification area 2 is a rose banknote of the same denomination / direction. If it is determined that there is, the result of the denomination identification of the rose banknote to be identified is determined to be the denomination of the denomination / direction of the object identification reference data. Further, when it is determined that any identification result for the identification area 1 and the identification area 2 is not a loose banknote of the denomination / direction of the target identification reference data, the denomination / direction of the rose banknote to be identified It is determined that there is a possibility that the identification result is not a loose banknote in the denomination / direction of the identification reference data. Thereby, even if the identification of the denomination of the banknote bundle is not correctly identified due to the influence of the bundling because the banding is included in one of the identification area 1 or the identification area 2, it is possible to correctly identify the denomination of the banknote bundle. It becomes possible.

  Next, the data configuration according to the present embodiment of the loose banknote processing unit 102 shown in FIG. 5 will be described with reference to FIG.

  The identification reference data 107a is data in which reference data associated with the denomination and direction is used as the possessed item of the record. In the example of the identification reference data 107a in FIG. 8, the reference data of the first denomination in the A direction is 1Ab00, 1Ab01, 1Ab02,..., 1Ab3f, and the denomination is the first denomination in the B direction. The data is 1Bb00, 1Bb01, 1Bb02, ..., 1Bb3f, the denomination is the first denomination, the reference data in the C direction is 1Cb00, 1Cb01, 1Cb02, ..., 1Cb3f, and the denomination is the first denomination It indicates that the reference data in the D direction is 1Db00, 1Db01, 1Db02,..., 1Db3f.

  The identification threshold data 107b includes a start position, an end position, and a determination threshold for each sub area of the identification area 1 associated with the denomination and direction, and a start position, an end position, and a determination threshold for each sub area of the identification area 2. This is the data that is held by the record.

  Since the rose banknote processing unit 102 is intended for rose banknotes that are not bound by a binding band, it is not necessary to divide the identification area into two, so only one of the identification areas is used and information on the entire area of the banknotes is used. Is set. In the example of the identification threshold data 107b in FIG. 8, the first sub-region of the identification region 1 in the A direction whose denomination is the first denomination is Z00, the end position is Z0f, the determination threshold is 1At0, 2 The start position of the third sub-region is Z10, the end position is Z1f, the determination threshold is 1 At1, the start position of the third sub-region is Z20, the end position is Z2f, the determination threshold is 1 At2, and the fourth sub-region This indicates that the start position of the region is Z30, the end position is Z3f, and the determination threshold is 1 At3. Moreover, the setting with respect to the identification area 2 in the A direction of the first denomination is not performed.

  Further, in the example of the identification threshold data 107b in FIG. 8, the start position of the first sub-region of the identification area 1 in the B direction whose denomination is the first denomination is Z00, the end position is Z0f, and the determination threshold is 1Bt0. The start position of the second sub-region is Z10, the end position is Z1f, the determination threshold is 1Bt1, the start position of the third sub-region is Z20, the end position is Z2f, the determination threshold is 1Bt2, and the fourth This indicates that the start position of the sub-region is Z30, the end position is Z3f, and the determination threshold is 1Bt3. Moreover, the setting with respect to the identification area | region 2 of the B direction of a 1st denomination is not performed.

  As described above, the bundle identification threshold data 107d has the same structure as the identification threshold data 107b.

  In the example of the bundle identification threshold value data 107d in FIG. 8, the start position of the first sub-region of the identification area 1 in the A direction whose denomination is the first denomination is Z00, the end position is Z07, and the determination threshold is 1At01. The start position of the second sub-region is Z10, the end position is Z17, the determination threshold is 1At11, the start position of the third sub-region is Z20, the end position is Z27, the determination threshold is 1At21, and the fourth The sub-region has a start position of Z30, an end position of Z37, and a determination threshold value of 1 At31. Further, the start position of the first sub-region of the identification area 2 in the A direction of the first denomination is Z08, the end position is Z0f, the determination threshold is 1At02, and the start position of the second sub-area is The end position is Z1f at Z18, the determination threshold is 1 At12, the start position of the third sub-region is Z28, the end position is Z2f, the determination threshold is 1 At22, the start position of the fourth sub-region is Z38 and the end position Indicates that Z3f and the determination threshold is 1 At32.

  Further, in the example of the bundle identification threshold value data 107d in FIG. 8, the start position of the first sub-region of the identification region 1 in the B direction whose denomination is the first denomination is Z00, the end position is Z07, and the determination threshold is With 1Bt01, the start position of the second sub-region is Z10, the end position is Z17, the determination threshold is 1Bt11, the start position of the third sub-region is Z20, the end position is Z27, the determination threshold is 1Bt21, 4 It shows that the start position of the third sub-region is Z30, the end position is Z37, and the determination threshold is 1Bt31. Further, the start position of the first sub-region of the identification area 2 in the B direction of the first denomination is Z08, the end position is Z0f, the determination threshold is 1Bt02, and the start position of the second sub-area is The end position is Z1f at Z18, the determination threshold is 1Bt12, the start position of the third sub-region is Z28, the end position is Z2f, the determination threshold is 1Bt22, the start position of the fourth sub-region is Z38 and the end position Is Z3f and the determination threshold is 1 Bt32.

  In the case of banknote bundles, since they are bundled with a binding band, the binding band is reflected in the image of the banknote bundle, and the denomination of the denomination may not be correctly performed due to the influence of the binding band. Therefore, the image data of the banknote bundle is divided into a left half identification area and a right half identification area, and the denomination is independently identified in the left half identification area and the right half identification area. By using the result identified in the region as the result of identifying the denomination of the banknote bundle, it is possible to identify the denomination while eliminating the influence of the binding band. Further, in dividing the area, it is possible to use more than half of the area without dividing the area even if the position of the binding band is determined. On the other hand, in the case of loose bills, there is no binding band in the first place, so there is no need to divide the identification area into two. Thereby, you may designate the whole area | region of a banknote in one identification area. Further, even when processing is divided into a left half identification area and a right half identification area, the determination threshold used for identifying the denomination of the banknotes is different from the determination threshold used for identifying the denomination of the banknote bundle. A threshold value may be set.

  Next, a processing procedure of data generation processing used in denomination identification processing by the learning processing unit 108f illustrated in FIG. 5 will be described. FIG. 9 is a flowchart showing a processing procedure of data generation processing used in denomination identification processing by the learning processing unit 108f.

  The learning processing unit 108f acquires image data of a predetermined number of banknotes for every banknote as a denomination identification target and for every placement direction with respect to the deposit stacking unit 70 of the rose banknote processing unit 102 ( Step S101).

  A learning processing unit for image data corresponding to any one direction of any one denomination of the banknote image data acquired in step S101 that has not yet been subjected to the processing in steps S102 to S105. 108f performs statistical processing (step S102). Specifically, the zone value for each zone shown in FIG. 7 is calculated from a plurality of image data corresponding to the denomination and direction to be processed, and the average and variance of the zone values are calculated.

  Based on the statistical processing performed in step S102, the learning processing unit 108f uses, as reference data corresponding to the denomination and direction to be processed in step S102, data having an average value for each zone as a zone value as identification reference data 107a. (Step S103). In the present embodiment, the zone value of the reference data is an average value, but an intermediate value for each zone may be obtained by statistical processing, and the obtained intermediate value may be used as the zone value of the reference data.

  Further, the learning processing unit 108f calculates a determination threshold value for each sub-region as a threshold value for loose banknotes corresponding to the denomination and direction to be processed in step S102 based on the statistical processing performed in step S102. It registers in the identification threshold value data 107b used in the banknote processing part 102 (step S104). Specifically, a threshold value for each sub-region is calculated according to a predetermined criterion based on the average and variance of the zone values of the zones included in the sub-region.

  Further, the learning processing unit 108f calculates a determination threshold for each sub-region as a threshold for the banknote bundle corresponding to the denomination and direction to be processed in step S102 based on the statistical processing performed in step S102 and bundles it. Registered in the bundle identification threshold data 107d used in the banknote processing unit 101 (step S105). Specifically, a threshold value for each sub-region is calculated according to a predetermined standard based on the average and variance of the zone values of the zones included in the sub-region. The reference for calculating the threshold value for loose banknotes and the reference for calculating the threshold value for banknote bundles are not necessarily the same.

  If all the image data acquired in step S101 has been processed in steps S102 to 105 (step S106; Yes), the process ends. If image data that has not been processed in steps S102 to 105 remains in the image data acquired in step S101 (step S106; No), the process proceeds to step S102.

  Next, the processing procedure of the discriminating process for denominations of loose bills in the loose bill processing unit 102 shown in FIG. 5 will be described. FIG. 10 is a flowchart showing the processing procedure of the denomination identification process for loose bills in the loose bill processing unit 102.

  The withdrawal bill identifying unit 108e acquires the image data of the rose bill that passes through the withdrawal identifying unit 96 that is transported in the withdrawal transport path 92, and stores it in the recognition target bill data 107c (step S201). The withdrawal banknote identification unit 108e is configured to select any one denomination and any one direction reference from a plurality of denominations registered in the identification reference data 107a and reference data for four directions for each denomination. Data is selected (step S202). Based on the reference data selected in step S202, the identification target banknote data 107c, and the setting of the sub area of the identification area 1 of the identification threshold data 107b corresponding to the reference data, the withdrawal banknote identification unit 108e An evaluation value is calculated for each sub-region of the identification region 1 for the image data of the rose banknote (step S203).

  When the evaluation value for each sub-region calculated in step S203 is not more than the determination threshold value for each sub-region defined in the identification threshold data 107b (step S204; Yes), the evaluation value calculated in step S203, gold The seed and direction are stored (step S205). If any of the evaluation values for each sub-region calculated in step S203 exceeds the determination threshold for each sub-region defined in the identification threshold data 107b (step S204; No), the process of step S205 is not performed. The process proceeds to step S206. If the processing from step S203 to step S205 has not been performed on the reference data for all denominations and directions registered in the identification reference data 107a (step S206; No), the process proceeds to step S202. .

  The processing from step S203 to step S205 has been performed on the reference data for all denominations and directions registered in the identification reference data 107a (step S206; Yes), and the evaluation value and gold stored in step S205 are stored. If there is a seed and a direction (step S207; Yes), the withdrawal banknote identification unit 108e, based on the evaluation value, the money type and the direction stored in step S205, the rose banknote obtained in step S201. The denomination and direction are specified (step S208), and the process ends. Specifically, when there is only one evaluation value, denomination and direction stored in step S205, the denomination and direction stored in step S205 is the money of the rose banknote from which image data was acquired in step S201. Determined to be species and direction. In addition, when there are a plurality of evaluation values, denominations and directions stored in step S205, the denomination and direction for the highest evaluation value among the plurality of existing evaluation values are the same as those obtained by acquiring the image data in step S201. It is determined that the banknote type and direction.

  In addition, when the evaluation value, denomination and direction stored in step S205 do not exist (step S207; No), the withdrawal banknote identification unit 108e denominations and directions of the rose banknotes whose image data has been acquired in step S201. Is determined to be impossible (step S209), and the process ends.

  Next, the internal configuration of the bundled bill processing unit 101 shown in FIG. 2 will be described. FIG. 11 is a block diagram showing an internal configuration of the bundled bill processing unit 101. As shown in FIG. 11, the bundled bill processing unit 101 includes a bundle deposit / withdrawal port 10, an opening / closing door 12, a bundle discharge port 13, a locking device 14, a bundle lifting / lowering passage 2, a bundle storage unit 3, a transport unit 4, and a binding printing unit 5. , A bundle transport unit 6, a storage unit 105, and a control unit 106.

  The storage unit 105 is a storage device including a hard disk device, a nonvolatile memory, and the like. The storage unit 105 includes identification reference data 105a, identification threshold data 105b, and identification target banknote data 105c.

  The identification reference data 105a, the identification threshold data 105b, and the identification target banknote data 105c have the same structure as the identification reference data 107a, the identification threshold data 107b, and the identification target banknote data 107c of the loose banknote processing unit 102. The identification reference data 105a has the same setting contents as the identification reference data 107a of the loose banknote processing unit 102. As the identification threshold value data 105b, bundle identification threshold value data 107d generated in advance by the loose banknote processing unit 102 is registered.

  The control unit 106 is a control unit that controls the entire bundled bill processing unit 101, and includes a deposit processing unit 106a, a withdrawal processing unit 106b, a collection processing unit 106c, a loading processing unit 106d, a scrutinization processing unit 106e, and an identification processing unit. 106f. Actually, a program corresponding to each functional unit is stored in a non-illustrated non-volatile memory such as a ROM, and this program is executed by a CPU (Central Processing Unit) so that a process corresponding to each functional unit is performed. Will be executed.

  When the deposit processing unit 106a receives an instruction for depositing a banknote bundle, the elevating stage 20 is set to the highest position (h1), the shutter of the bundle deposit / withdrawal port 10 is opened, and the insertion of the banknote bundle is awaited. Then, when a predetermined time passes or a deposit button (not shown) is pressed, the shutter is closed and the elevating stage 20 is lowered to the lowest position (h3), and the swing-back part 4a is returned from the retracted position to the horizontal transport position. Then, the elevating stage 20 is raised again, the transport belt 44 is driven, and one bundle of the banknote bundle B at the uppermost position is transported to the right in FIG. At this time, the banknote bundle B moves on the identification part 43, and the identification process part 106f reads the image of the lower surface of the banknote bundle B, and identifies a money type. After the denomination is identified, the opening / closing plate 34 of the bundle storage of the corresponding denomination is opened, and the elevating stage 30 of the bundle storage is moved to a position where the banknote bundle B to which the highest banknote bundle is added is accepted. When the banknote bundle B falls from the transport passage, the banknote bundle B is stored in the bundle storage. When there is a remaining banknote bundle B, the above-described operation is repeated.

  If the withdrawal processing unit 106b receives an instruction for banknote bundle withdrawal, the banknote bundle of the designated denomination is unloaded from the bundle storage unit 3 and the denomination of the banknote bundle unloaded by the identification unit 43 is confirmed. The payout to the bundle deposit / withdrawal port 10 is performed. Further, when the withdrawal processing unit 106b receives an instruction for the bundled withdrawal, the bundled printing unit 5 binds the unbound banknote bundle received from the loose banknote processing unit 102 with the binding band. Thus, the bundle of banknotes bound to the bundle deposit / withdrawal port 10 is paid out.

  When the collection processing unit 106c receives an instruction to collect the banknote bundle, the collection processing unit 106c collects the banknote bundle stored in the bundle storage unit 3 to the bundle discharge port 13. Further, when the collection processing unit 106c receives an instruction for bundling collection, the collection unit 106 binds the unbound banknote bundle received from the bulk banknote processing unit 102 by the bundle transport unit 6 with the binding band by the binding printing unit 5, The banknote bundle bound to the bundle discharge port 13 is collected.

  When the loading processing unit 106d receives an instruction to load the bundle outside the apparatus, the identifying unit 43 identifies the banknote bundle inserted into the bundle deposit / withdrawal port 10 or the bundle discharge port 13 and is identified. It loads in bundle storage 3a-3e according to a money type. Further, when the loading processing unit 106d receives an instruction for automatic sorting and loading, the banknote bundle unloaded from the bundle storage 3e in which the banknote bundle of the mixed denomination is stored, and the banknote unloaded by the identification unit 43. The bundle denomination is identified and loaded into the bundle storages 3a to 3d according to the identified denomination. Further, when the loading processing unit 106d receives an instruction for binding loading, the unloading banknote bundle received from the loose banknote processing unit 102 by the bundle transport unit 6 is bound by a binding band by the binding printing unit 5, The identification unit 43 identifies the denomination, and loads the bundle storages 3a to 3d according to the identified denomination.

  When the scrutinization processing unit 106e receives a scrutiny instruction, the scrutinization processing unit 106e once carries out the banknote bundle stored in the bundle storages 3a to 3e to the bundle lifting passage 2, and the identification unit 43 identifies the denomination. Re-store in bundle storage 3a-3d according to the identified denomination. However, when the denomination cannot be identified by the identification unit 43, the banknote bundle is not stored in the bundle storages 3a to 3d, and the banknote bundle is waiting to be taken out from the bundle deposit / withdrawal port 10 or the bundle discharge port 13. It becomes.

  The identification processing unit 106f acquires an image of the banknote bundle to be identified by the identifying unit 43 and stores it in the identification target banknote data 105c. Further, the denomination of the banknote bundle to be identified is identified based on the identification reference data 105a, the identification threshold data 105b, and the identification target banknote data 105c. The identification processing unit 106f is common to the processing contents of the withdrawal banknote identification unit 108e of the loose banknote processing unit 102 shown in FIG. 5, and the identification reference data 107a, the identification threshold value data 107b used in the bulk banknote processing unit 102, and Processing is performed using the identification reference data 105a, the identification threshold value data 105b, and the identification target banknote data 105c, respectively, instead of the identification target banknote data 107c.

  Since the withdrawal banknote identification unit 108e of the loose banknote processing unit 102 is common to the processing content of the identification processing unit 106f of the bundle banknote processing unit 101, the identification target banknote data 105c is also identified by the banknote processing unit 102. The resolution needs to be the same as 107c. However, the conveyance speed in the conveyance unit 4 of the bundled bill processing unit 101 and the conveyance rate of the loose banknotes in the withdrawal conveyance path 92 of the loose banknote processing unit 102 are not necessarily the same. The conveyance unit 4 of the bundle bill processing unit 101 and the withdrawal conveyance path 92 of the loose bill processing unit 102 are provided with a rotary encoder (not shown), and the identification unit 43 of the bundle bill processing unit 101 and the withdrawal of the loose bill processing unit 102 are provided. The gold identifying unit 96 can acquire data of the same resolution by acquiring data at predetermined intervals based on the output pulses of the respective rotary encoders.

  Next, the processing procedure of the banknote bundle denomination identifying process in the bundled banknote processing unit 101 shown in FIG. 2 will be described. FIG. 12 is a flowchart showing a processing procedure for denomination identification of banknote bundles in the bundle banknote processing unit 101.

  The identification processing unit 106f acquires the image data of the banknote bundle conveyed by the conveyance unit 4 and passes through the identification unit 43, and registers it in the identification target banknote data 105c (step S301). The identification processing unit 106f obtains reference data for any one denomination and any one direction from the plurality of denominations stored in the identification reference data 105a and the reference data for the four directions for each denomination. Select (step S302). In addition, the identification processing unit 106f selects, from the identification area 1 or the identification area 2, as an evaluation target, an unevaluated identification area with respect to the denomination and direction selected in step S302 (step S303). Based on the reference data selected in step S302, the identification target banknote data 105c, and the setting of the sub area of the identification area selected in step S303 of the identification threshold data 105b corresponding to the reference data, the identification processing unit 106f. An evaluation value is calculated for each sub-region of the identification area for the image data of the banknote bundle to be identified (step S304).

  When the evaluation value for each sub-region calculated in step S304 is not more than the determination threshold value for each sub-region defined in the identification threshold data 105b (step S305; Yes), the evaluation value calculated in step S304, gold The identification information of the identification region selected in step S303 is stored (step S306). If any of the evaluation values for each sub-region calculated in step S304 exceeds the determination threshold for each sub-region defined in the identification threshold data 105b (step S305; No), the process of step S306 is not performed. The process proceeds to step S307. If there is an identification area in which the processing from step S304 to step S306 is not evaluated with respect to the reference data selected in step S303 (step S307; Yes), the process proceeds to step S303. Further, the processing from step S304 to step S306 has been evaluated for all the identification areas with respect to the reference data selected in step S303 (step S307; No), and the processing from step S303 to step S307 is performed. When the reference data for all denominations and directions registered in the identification reference data 105a has not been executed (step S308; No), the process proceeds to step S302.

  The processing from step S303 to step S307 has been performed on the reference data for all denominations and directions registered in the identification reference data 105a (step S308; Yes), and the evaluation value and gold stored in step S306 are stored. If there is identification information of the seed, direction, and identification area (step S309; Yes), the identification processing unit 106f performs step based on the evaluation value, denomination, direction, and identification area identification information stored in step S306. The denomination and direction of the banknote bundle for which image data was acquired in S301 are specified (step S310), and the process is terminated. Specifically, when there is only one evaluation value, denomination, direction, and identification area identification information stored in step S306, the denomination and direction stored in step S306 are the image data in step S301. It determines with it being the money type and direction of the acquired banknote bundle. In addition, when there are a plurality of pieces of evaluation value, denomination, direction, and identification area identification information stored in step S306, the denomination and direction for the highest evaluation value among the plurality of existing evaluation values are determined in step S301. It determines with it being the money type and direction of the banknote bundle which acquired image data.

  In addition, when the evaluation value, denomination, direction, and identification area identification information stored in step S306 does not exist (step S309; No), the identification processing unit 106f acquires the banknote bundle whose image data has been acquired in step S301. It is determined that the denomination and direction cannot be specified (step S311), and the process ends.

  The flowchart which shows the processing procedure of the identification processing of the denomination of the rose banknote in the rose banknote processing part 102 shown in FIG. 10, and the processing procedure of the identification processing of the denomination of the banknote bundle in the bundle banknote processing part 101 shown in FIG. The flowchart shown in FIG. 12 differs from the flowchart shown in FIG. 12 in the part where the processing for two identification areas is repeated in steps S303 and S307, but the identification threshold value data 107b of the banknote processing unit 102 is different. 9, since only the identification area 1 is set to be valid as shown in FIG. 9, the denomination of the denomination of the banknote banknote in the banknote banknote processing unit 102 is performed by the money of the banknote bundle in the banknote banknote processing unit 101. It can be replaced by a seed identification process.

  As described above, common reference image data used for identifying denominations of rose banknotes and bundled banknotes is prepared based on image data acquired using genuine rose banknotes that are not bundled by a cable tie. It is possible to set determination position information and a determination threshold value that is a determination reference for an evaluation value corresponding to the determination position for each of two determination target positions as a determination reference used for identifying the denomination of the bill. Since the judgment standard used for identifying the banknote denomination and the judgment standard used for identifying the banknote denomination of the bundle can be set separately, the denomination of the rose banknote and the money of the banknote of the bundle It is possible to reduce time and effort required for development of processing related to species identification and preparation of information necessary for processing.

  In the above-described embodiment, the identification reference data 105a and 107a used for denomination identification have the same structure and set values in the denomination identification of the banknote bundle and the denomination identification of the loose banknote, and the identification threshold data 105b. 107b have a common structure and set values are set to different values for the denomination identification of the banknote bundle and the denomination identification of the loose banknote, but the present invention is not limited to this. For example, the identification threshold data 105b for banknote bundles may be used as the identification threshold data 107b for loose banknotes. In addition, in this embodiment, the zone is divided into 64 zones of 4 × 16. However, this is only an example, and even if the number of zones is smaller than 64, the number of zones is more than 64. It may be the number of zones.

  In the above-described embodiment, the evaluation value is calculated for each sub-region of the identification region based on the image data of the banknote to be identified and the reference data prepared in advance, and is compared with the threshold set for each sub-region. If the similarity for each sub-region is determined to be high, the denomination and direction for the identification region are determined to be the denomination and direction of the reference data used. However, the present invention is not limited to this content. For example, if the number of sub-areas determined to be high is equal to or greater than a predetermined number, the denomination and direction for the identification area may be determined to be the denomination and direction of the used reference data. Further, for example, the evaluation value of the entire identification region is calculated based on the importance set for each sub-region of the identification region and the similarity for each sub-region, and the denomination of the reference data and You may make it determine whether it is a direction.

  In addition, each configuration illustrated in the above-described embodiments is functionally schematic and does not necessarily need to be physically configured as illustrated. That is, the form of distribution / integration of each device is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed / integrated in an arbitrary unit according to various loads or usage conditions.
