(C) of FIG. 7 is a defective banknote with a remaining rate of banknote S of 30%.

  S501: The control unit 20 displays a transaction selection screen as a customer operation display screen on the display unit 21. For example, the control unit 20 displays a transaction selection screen on the display unit 21 triggered by the fact that the person in charge of the counter can be correctly authenticated by the information output by the fingerprint sensor 7 and the information read by the card reading unit 6.

  FIG. 6A is a diagram illustrating an example of the transaction selection screen 60. As shown in FIG. 6 (a), on the transaction selection screen 60, various buttons for a transaction person to select a transaction, such as a deposit button 601, a withdrawal button 602, a bill exchange button 603, etc. are displayed for each operation mode. Is displayed.

  S502: When a customer wishes to exchange a bill into a genuine bill, and the bank representative presses the bill exchange button 603, the control unit 20 accepts the selection of the bill exchange button 63 displayed on the display unit 21. . At this time, the control unit 20 determines whether or not the accepted button is the banknote exchange button 63. When it is determined that the accepted button is not the banknote exchange button 63 (step S502; No), the control unit 20 determines that the deposit button 601 and the withdrawal button 602 are selected, and these other operation modes S504 (non-operational). Move to (shown). In the following, the case of the banknote exchange mode has been described, but the same applies to the case of the deposit mode and the withdrawal mode. That is, the present invention can be applied to various processes that pass through the identification unit 15 and identify bills. In the deposit mode and the withdrawal mode, the cash can be read as deposit or withdrawal by the following process.

  S503: When the control unit 20 determines that the accepted button is the bill exchange button 63 (step S502; Yes), the control unit 20 displays the exchange bill amount selection screen 61 on the display unit 21 as a customer operation display screen.

  FIG. 6B is a diagram illustrating an example of the money amount selection screen 61. As shown in FIG. 6B, a button for selecting the denomination of the exchange bill is displayed on the money amount selection screen 61. In FIG. 6B, a 1000 rupee button 611, a 500 rupee button 612, a 100 rupee button 613, a 50 rupee button 614, and a 20 rupee button 615 are displayed by taking banknotes distributed in India as an example. In FIG. 6B, a cancel button 616 for canceling the exchange transaction is displayed. When the contact person in charge depresses the button of the denomination that the customer wants to exchange, the control unit 20 accepts the selection of the bill exchange button pressed as the customer operation display screen on the display unit 21.

  In addition, when determining the denomination of paper sheets based on determination of S506 mentioned later, the structure which does not select the denomination of exchange banknote may be sufficient. Conversely, a configuration in which the denomination determination in S506 is not performed may be performed by performing S503. In addition, when one kind of denomination is handled by the paper sheet processing apparatus 3, it is not necessary to select or determine the denomination in S503 and S506.

  S505: The deposit port 11 accepts a bill inserted from the person in charge at the window. In addition, when the inserted banknote is a defective banknote having a low remaining rate as shown in FIGS. 7B and 7C, there is a high possibility that a conveyance failure such as a jam will occur during the conveyance. Therefore, in such a case, you may insert | insert between the transparent sheet | seat of the same size as the inserted | deleted banknote and the correct banknote of the money type of the defective banknote. In this case, the paper sheet handling apparatus 3 transports the transparent sheet sandwiching the missing banknotes to the identification unit 15, determines the denomination and authenticity by a method described later, and then sandwiches the missing banknotes to the temporary storage unit 14. The transparent sheet is conveyed and put on hold.

  The transparent sheet is a sheet-like transport medium in which, for example, two transparent sheets made of a material such as polypropylene are stacked and a bill is sandwiched therebetween, as in a general clear file. Of the four sides of the transparent sheet, two adjacent sides become binding sides, the other two adjacent sides open, a defective banknote can be inserted from this portion, and can be sandwiched between the sheets. When a transparent sheet sandwiching a defective banknote is inserted into the deposit port 11, it is set so that one side of the binding side that is the width direction of the bill is the front side of the deposit port 11 that is the upstream side in the transport direction. do it. By setting the transparent sheet by such a method, the defective banknotes sandwiched between the transparent sheets conveyed from the deposit port 11 are detached from the transparent sheet in the middle of the conveyance, and the defective banknotes cause a conveyance leakage (for example, jam) ) Will not occur. In this example, the transparent sheet as described above is used as a transport medium for transporting the defective banknote, but as described later, if the material can determine the denomination and authenticity of the defective banknote, It may not be particularly transparent. Further, three sides of the four sides of the transparent sheet may be bound sides, two opposite sides may be bound sides, or three sides may be bound sides.

  S506: The control unit 46 calculates the outer area of the banknote from the outer shape of the banknote detected by the optical line sensor 44 of the identification unit 15, and reads the optical pattern pattern of the banknote detected by the optical line sensor 44. To determine the denomination of the bill. For example, the control unit 46 defines an area in which the optical line sensor 44 detects the reflected light from the bill as an outer shape, and the area of the outer shape and the area of the correct bill stored in the storage unit 33 for each denomination in advance. Are compared to determine the degree of coincidence between the two. Moreover, the control part 46 compares the optical pattern pattern of the banknote with the registered optical pattern pattern previously memorize | stored in the memory | storage part 33 for every money type, and determines both coincidence. The control part 46 will determine with the conveyed banknote being a banknote of the money type, if the said external area or the coincidence degree of the said optical pattern pattern is more than the predetermined threshold value.

  S507: The control unit 46 calculates the area of the genuine note portion of the conveyed banknote in the authenticity line sensor 45 of the identification unit 15. For example, the control part 46 is a material component which shows the registration authenticity determination information by which the material component which is the authenticity determination information of the conveyed banknote is previously memorize | stored in the memory | storage part 33 for every money type for every block mentioned later. It is determined whether or not. When the material component of the conveyed banknote is a material component that matches the material component stored in the storage unit 33, the control unit 46 determines that the conveyed banknote is a denomination of the denomination, Calculate the area. A specific determination method and calculation method will be described later with reference to FIG.

  S508: The control unit 46 notifies the control unit 30 of the denomination, authenticity, and genuine note area of the conveyed banknote.

  S509: The control unit 30 refers to the area of the denomination, authenticity, and genuine note part of the banknote received from the identification unit 15 in S508 and the denomination selected in S503. A ratio of the area is obtained, a banknote value corresponding to the ratio is calculated, a banknote that can be exchanged is determined, and a cashing result screen 63 is displayed on the display unit 21. In this example, the control part 30 determines the banknote of exchangeable denomination by determining whether the ratio of the area of a genuine note part is larger than 65% which is a predetermined threshold value. Yes. For example, as shown in (a) of FIG. 7, when the ratio of the area of the genuine bill portion of the missing bill is larger than 65% with respect to the genuine bill (S509; Yes), the conveyed bill is the same bill bill. It is determined that the exchange is possible, and a cash result screen 63 is displayed on the display unit 21.

  FIG. 6C shows an example of the cash result screen 63. As shown in FIG. 6C, the cash result screen 63 can be exchanged with the bill 631 of the denomination selected in S503 and the genuine bill area 632 showing the ratio of the area of the genuine bill portion. The banknote 633 of a denomination with a certain value is displayed on the cash result screen 63. In (c) of FIG. 6, 1,000 rupees are selected as the banknote of exchange source, the ratio of the area of the genuine note portion is 80%, and this numerical value is larger than the predetermined threshold value of 65%. The exchangeable denomination banknote indicates that it is 1,000 rupees of the same denomination as the exchange denomination.

  S510: When the ratio of the area of the genuine note portion of the missing bill is larger than 65% with respect to the correct note (S509; Yes), the control unit 30 further withdraws the cash amount displayed on the cash result screen 63. It is determined whether or not. For example, when the confirmation button indicating the intention to exchange displayed on the cashing result screen 63 shown in FIG. 6C is pressed, the control unit 30 withdraws the cash amount displayed on the cashing result screen 63. Then, it determines (S510; Yes). By pressing the confirmation button, it is possible to confirm the intention of replacement, and it is possible to prevent customer operation mistakes.

  S511: The control unit 30 determines that the control unit 30 does not have a genuine bill portion area ratio of missing banknotes larger than 65% with respect to the correct banknote (S509; No), and further, the genuine banknotes of the missing banknote with respect to the main banknote. It is determined whether or not the ratio of the area of the part is larger than a predetermined threshold value of 40% (S511). For example, as shown in (b) of FIG. 7, when the ratio of the area of the genuine bill portion of the missing bill is larger than 40% with respect to the regular bill (S511; Yes), the conveyed bill is a half-price genuine bill. It is determined that the exchange is possible, and a cash result screen 64 is displayed on the display unit 21.

  FIG. 6D shows an example of the cash result screen 64. As shown in FIG. 6 (d), the cash result screen 64 can be exchanged with a bill 641 of the denomination selected in S503 and a genuine bill area 642 indicating the ratio of the area of the genuine bill portion. A denomination of denomination 643 is displayed on the cash result screen 64. In (d) of FIG. 6, 1,000 rupees are selected as the exchange source banknote, and the ratio of the area of the genuine note portion is 48%, which is larger than a predetermined threshold value of 40%. The exchangeable denomination banknote indicates that the denomination is 500 rupees, which is half the price of the denomination of the exchange source.

  S512: When the ratio of the area of the genuine note portion of the missing bill is larger than 40% with respect to the correct note (S511; Yes), the control unit 30 further withdraws the cash amount displayed on the cash result screen 64. It is determined whether or not. For example, when the confirmation button indicating the intention to exchange on the cashing result screen 64 shown in FIG. 6D is pressed, the control unit 30 determines to withdraw money with the cashing amount displayed on the cashing result screen 64. (S512; Yes).

  S513: When the confirmation button is pressed in S510 or S512, the control unit 30 collects the inserted banknotes, draws out the correct banknotes from the storage unit 17, conveys them to the withdrawal port 12, and dispenses them. For example, when it is confirmed that the control unit 30 is exchanged for a correct bill of the same denomination (S510; Yes), any of the storage units 17a to 17d in which the correct bill of the denomination is stored. The correct bills are fed out from the storage unit and conveyed to the withdrawal port 12 for withdrawal, and the defective banknotes of the exchange source stored in the temporary storage unit 14 are conveyed to the collection unit 18 and collected. Moreover, when it is confirmed that the control part 30 replace | exchanges for a genuine banknote of a denomination of half price (S512; Yes), the storage part 17a-d in which the half price of a genuine banknote of that denomination is stored. The correct banknotes are fed out from any of the storage units and transported to the withdrawal port 12 for withdrawal, and the exchange-deficient banknotes stored in the temporary storage unit 14 are transported to the recovery unit 18 and collected.

  S514: When it is determined that the control unit 30 does not pay out with the cash amount displayed on the cash result screen 63 (S510; No), or when it is determined that no cash is displayed with the cash amount displayed on the cash result screen 64 ( S512; No), it is judged that there is no intention to exchange the banknote, and the inserted banknote of the exchange source is conveyed to the withdrawal port 12 and returned. Moreover, the control part 30 does not have the value of a banknote, when the ratio of the area of the genuine note part of a defect | deletion banknote is not larger than 40% with respect to a regular bill (S511; No) like FIG.7 (c). For this reason, it is determined that the exchange is impossible, and a cash result screen 65 is displayed on the display unit 21.

  FIG. 6E shows an example of the cash result screen 65. As shown in FIG. 6 (e), the cash result screen 65 includes a bill 651 of the denomination selected in S503, a genuine bill area 652 indicating the ratio of the area of the genuine bill portion, and a non-exchangeable bill. A message 653 indicating that it is possible is displayed on the cash result screen 65. In FIG. 6 (e), 1,000 rupees are selected as the exchange source banknote, the ratio of the area of the genuine note portion is 30%, and this value is not larger than the predetermined threshold of 40%. , Indicating that there are no exchangeable denomination banknotes.

  In addition, the control part 30 is exchanged for the cash bill result screen 63 displayed when the conveyed banknote is exchangeable for the same amount of the correct bill (S509; Yes), or the conveyed bill is the half price of the correct bill. Instead of the cash result screen 64 displayed when it is determined that it is possible (S511; Yes), for example, a cash result screen 66 including the image data of the outer shape of the defective banknote calculated in S506 and the authenticity of the defective banknote is displayed. May be.

  FIG. 6F shows an example of the cash result screen 66. As shown in FIG. 6 (f), the cash result screen 66 can be exchanged with a bill 661 of the denomination selected in S 503 and a genuine note area 662 indicating the ratio of the area of the genuine note part. The banknote 663 of a valuable denomination and the image data 664 of the outline of the missing banknote are displayed on the cash result screen 66. In (f) of FIG. 6, as in FIG. 6 (c), the banknote of the exchange source, the ratio of the area of the genuine note part, the banknote of the exchangeable denomination is displayed, and the ratio of the area of the genuine note part is It shows that 80% of image data is displayed. Thus, by displaying the image of the lost banknote, the person in charge of the window and the customer can easily determine the exchange result.

  Moreover, in the above, the banknote of the exchangeable denomination was determined by determining whether the ratio of the genuine note part of a defect | deletion banknote is larger than the predetermined threshold value. However, since the degree of damage or disappearance of the inserted banknote varies depending on the country or region, it may be desirable to be able to change the threshold appropriately. Therefore, for example, the control unit 30 may display the banknote cashing condition setting screen 67 and accept a change in threshold value from the person in charge of the window.

  FIG. 7G is a diagram showing an example of the banknote exchange condition setting screen 67. As shown in FIG. 7 (g), the banknote exchange condition setting screen 67 is provided with an input field for accepting setting or changing of a threshold value indicating the ratio of the genuine note portion of the lost banknote. In FIG. 7 (g), as an example, it can be seen that an input field 671 for the condition for converting to 1,000 rupees and an input field 672 for the condition for converting to 500 rupees are displayed. As described above, by enabling the setting and changing of the threshold value, it is possible to determine the denomination of the correct banknote to be exchanged according to the degree of damage or disappearance of the missing banknote.

  Thus, in the said process, since the denomination of the banknote to replace | exchange is determined based on the conditions defined according to the value of the banknote to replace | exchange, and the area of a genuine note part, to the correct banknote suitable for a banknote value Can be exchanged.

  In addition, as a standard for the exchange, when the banknote to be exchanged is a high-value banknote of a certain value or more (for example, 1000 rupees), for example, when the ratio of the area of the genuine bill portion to the genuine bill is larger than 65% Withdraws the same amount of banknotes as the banknotes to be exchanged, and if the ratio of the area of the genuine bills to the genuine bills is greater than 40% and less than 65%, the bills to be exchanged and half the bills are withdrawn. When the ratio of the area of the genuine note portion to 40% is 40% or less, the bill is controlled so as not to be dispensed. In addition, when the bill to be exchanged is a low-value bill with a value less than a certain value (for example, 500 rupees), if the ratio of the area of the genuine bill portion to the genuine bill is 50% or more, a bill having the same amount as the bill to be exchanged Withdrawing money, control is performed so that banknotes are not withdrawn when the ratio of the area of the genuine bill to the genuine bill is less than 50%. Thus, the conditions to exchange according to the value of a bill can be defined.

  Moreover, as shown to (c)-(f) of FIG. 6, on the display part 21 of the window terminal device 2, the ratio of the area of the genuine note part with respect to a genuine note, and the banknote to be exchanged determined by the control part 46 Is displayed, and an operation indicating the intention to exchange with the banknote to be exchanged is accepted from the input unit 22 of the window terminal device 2, and the banknote is withdrawn, so that the banknote is exchanged after grasping the exchanged banknote. Can do.

  The outer shape line sensor 44 is composed of a line sensor that detects the amount of reflected light of the banknote, displays the reflection image detected by the outer shape line sensor 44 on the display unit 21 of the window terminal device 2, and A different color from the counterfeit or modified ticket portion other than the genuine note portion (for example, the region surrounded by the dotted line portion of the image data 664 shown in FIG. 6F is surrounded by red and the actual situation other than that) Alternatively, the display area 21 may be the green area). Moreover, the outline line sensor 44 is comprised from the line sensor which detects the transmitted light amount of a banknote, displays the transmitted image which the external shape line sensor 44 detected on the display part 21 of the window terminal device 2, and detects the reflected light quantity of a banknote. Similarly to the case, the display part 21 may be configured such that the genuine note part for the genuine note and the counterfeit or modified ticket part other than the true note part are different colors. By setting it as such a display method, the ratio of a genuine note part can be grasped at a glance.

  Next, a method for determining the area of the genuine note portion in S507 of FIG. First, the optical line sensor 44 and the true / false line sensor 45 provided in the identification unit 15 each time a cycle of a clock output from the encoder unit 12 (also referred to as a “carrying cycle”) every time a bill is conveyed a certain distance. Is controlled. Actually, the optical line sensor 44 is controlled by the clock cycle output from the encoder unit 12 and is read sequentially for each line-shaped image region (block) divided by a certain transport distance unit.

  (A) of FIG. 8 is a two-dimensional image in which the optical line sensor 44 detects a transparent sheet sandwiching the defective banknote conveyed to the identification unit 15. The region 81a shows, for example, a portion where the transparent sheet has passed through the optical line sensor 44 in FIG. In FIG. 8, the transparent sheet is conveyed from the upper side to the lower side (x direction).

  In addition, the resolution | decomposability of the vertical direction (x direction) of (a) of FIG. 8 becomes the conveyance distance of the banknote S in a conveyance period. Further, the resolution in the horizontal direction (y direction) in FIG. 8A corresponds to the number of arrays in the main scanning direction of the light receiving portions of the optical line sensor 44. As the number of light receiving units arranged in the main scanning direction is larger and the transport distance unit is shorter, the area of the detected banknote can be calculated in more detail.

  FIG. 8B is a two-dimensional image in which the true / false line sensor 45 detects the genuine note portion of the defective banknote conveyed to the identification unit 15. A region 81b indicates a portion of the region 81a in FIG. 8A where only a transparent sheet having no missing banknote passes through the true / false line sensor 45. A region 82 indicates a genuine note portion in which a defective banknote is actually detected by passing through the true / false line sensor 45. In FIG. 8A, the outer shape line sensor 44 detects the reflected light from the transparent sheet having the same size as the banknote, but the reflected light from the transparent sheet only part and the part sandwiching the defective banknote between the transparent sheets. The value is different from the reflected light. Therefore, if the outer shape line sensor 44 detects the reflected light at least in a region of a certain value or more, the region may be determined as the outer shape of the transparent sheet.

  Then, the control unit 46 determines the area of the material component that matches the material component stored in advance in the storage unit 33 and detected by the true / false line sensor 45 among the transparent sheets in the region detected by the optical line sensor 44. Calculate and set the area of the genuine note part. The control unit 46 can compare the area 82, which is the area of the genuine note portion, with the area of the region 81a, and calculate the area ratio of the genuine note portion.

  In FIG. 8, the defective banknotes are transported with the transparent sheet sandwiched between them, and the authenticity of the defective banknotes is determined during the transport. However, the control unit 46 is stored in advance in the storage unit 33 for each denomination. It is also possible to read the area of the genuine bill indicating the size of the genuine bill and compare the area of the genuine bill with the region 82 to calculate the area ratio of the genuine bill portion.

In FIG. 8, the outer shape line sensor 44 and the true / false line sensor 45 are composed of 18 elements in the main scanning direction (y direction), and one block 83 is associated with the elements. Therefore, the control unit 46 can determine the area of the entire genuine note portion by determining the number of blocks 83 and the ratio of the area 81 a occupied in one block 83.
In addition, the resolution | decomposability of the vertical direction (x direction) of (b) of FIG. 8 becomes the conveyance distance of the banknote S in a conveyance period. Further, the horizontal resolution in FIG. 8B corresponds to the number of arrays in the main scanning direction of the light receiving portions of the true / false line sensor 45. As the number of light receiving units arranged in the main scanning direction is larger and the transport distance unit is shorter, the true / false sensor determination of the detected banknote can be calculated with higher definition.

  Further, the area 81a shown in FIG. 8 (a) and the area 81b shown in FIG. 8 (b) are divided in units of transport distance by the encoder unit 12 in the vertical direction, and the known direction of each line sensor in the horizontal direction. Since it is divided by the number of arrangements and positions, it can correspond one-on-one.

  Although the present embodiment has been described by taking a defective banknote as an example, the present invention can also be applied to a case where the banknote is a fake bill. That is, when the bill is a fake ticket or a fake ticket, the true / false line sensor 45 uses the material constituting the correct bill even if the area detected by the outer shape line sensor 44 has the same outer area as the correct note. Since different materials are detected, it is determined that the bill is a fake note, and the ratio of the area of the genuine note portion is calculated as 0%. Furthermore, not only when all the banknotes are counterfeit tickets or counterfeit tickets, but also in the case of a partially counterfeit ticket partially counterfeited or a partially counterfeit ticket partially altered, the same as above. be able to.

  As described above, according to the first embodiment, it is possible to correctly determine and identify the denomination and authenticity not only for a defective banknote but also for a counterfeit or altered ticket.

(Second Embodiment)
In the first embodiment, a case has been described in which a denomination or authenticity is determined and identified for a counterfeit note or a counterfeit note by taking a missing note as an example. However, counterfeit and counterfeit tickets include counterfeit and counterfeit tickets that are a combination of genuine bills of different denominations. Therefore, in the following, a process for a counterfeit ticket or a modified ticket in which genuine bills of different denominations are bonded together will be described.

  FIG. 9 is a flowchart showing an operation related to the second embodiment. Since the difference from the first embodiment is steps S907 to S909 in the flowchart, the description of the same steps as those of the first embodiment is omitted. In S907 to S909, not only the genuine note determination by the genuine line sensor 45 but also the optical pattern detected by the optical line sensor 44 is used not only for the denomination determination but also for the authenticity determination. A specific determination method will be described later with reference to FIG.

  (A) of FIG. 10 is a two-dimensional image when the optical line sensor 44 conveys the banknote which the different denominations, for example, the 500 rupee genuine note and the 1000 rupee genuine note, were conveyed to the identification part 15. . A region 111 is a portion where the transparent sheet has passed through the optical line sensor 44 in FIG. In FIG. 10, the transparent sheet is conveyed from above to below (x direction). Although the case where a transparent sheet is used is described in this example, the case where a transparent sheet is not used can be considered in the same manner as in the first embodiment.

  FIG. 10B is a two-dimensional image in which the true / false line sensor 45 detects the genuine note portion of the banknote conveyed to the identification unit 15. The region 112a is a portion where a missing banknote corresponding to 1000 rupees of the banknote has passed through the true / false line sensor 45. The region 113a is a portion where a portion of the banknote corresponding to 500 rupees passes through the authenticity line sensor 45 in the banknote.

  FIG. 10C is an image obtained by normalizing the region 111 of FIG. 10A by rotating the region 111 in the reference direction by an angle θ. In the figure, the area 112b is a part corresponding to 1000 rupees, and in the figure, the area 113b is a part corresponding to 500 rupees. In this example, the angle θ is the angle when the bill is rotated counterclockwise to the axis in the main scanning direction (y direction).

  In S907 of FIG. 9, the control unit 46 calculates the area of the genuine note portion of the conveyed banknote by the authenticity line sensor 45 of the identification unit 15. For example, the control part 46 determines whether the material component of the conveyed banknote is a material component previously memorize | stored in the memory | storage part 33 for every money type. When the material component of the conveyed banknote is a material component that matches the material component stored in the storage unit 33, the control unit 46 determines that the conveyed banknote is a denomination of the denomination, Calculate the area. In this example, since the banknote is composed of genuine bills of two denominations, the area of the genuine note portion is calculated for each denomination. As a result, the area of the region 112a and the area of the region 113a shown in FIG. 10B can be calculated by a method similar to that in the first embodiment. At this stage, each portion of the region 112a and the region 113a becomes a genuine note portion.

  In S908 and S909 of FIG. 9, the control unit 46 further determines the authenticity of the four postures of the banknotes with respect to the denomination (eg, 1000 rupees) set in step S903 of FIG. Specifically, the control unit 46 (1) moves the banknote including the region 112b and the region 113b illustrated in (c) of FIG. 10 in the θ direction in addition to the posture illustrated in (c) of FIG. A posture rotated up and down by rotating 180 degrees, (3) a posture rotated upside down by rotating the banknote including the region 112b and the region 113b in a direction perpendicular to the θ direction (z direction), and (4) further reversed upside down. The authenticity of the area 112b and the area 113b is further determined with respect to the banknotes in the four postures, which are the postures in which the banknotes in the posture rotated 180 degrees in the θ direction and reversed upside down.

  For example, the denomination set in S903 is 1000 rupees, and the denomination determined by the optical line pattern detected by the outline line sensor 44 for the region 111 shown in FIG. 10A is 1000 rupees. The control unit 46 rotates and normalizes the region 111 in the same posture as the postures (1) to (4). And the control part 46 rotates the registration optical pattern pattern of 1000 rupees previously memorize | stored in the memory | storage part 33 to the attitude | position of said (1)-(4), and in each attitude | position of (1)-(4). The degree of coincidence of the optical pattern is determined. The degree of coincidence is determined, for example, for each block 114 similar to the block of FIG. 8 by determining whether or not the difference in pixel value level is within a certain range, and the difference in pixel value level is within a certain range. If it is determined that the pixel is within the range, the block is determined to be a pixel of 1000 rupees.

  The control unit 46 determines the degree of coincidence for all the blocks in the area 112b and the area 113b shown in FIG. As a result, even if the external shape is the same as 1000 rupees, the area where the optical pattern is not the same as 1000 rupees and the genuine notes of different denominations are embossed, and the area other than the bonded area ((c in FIG. 10) ), It can be determined that the area 112b) is a genuine note portion of 1000 rupees.

As described above, according to the second embodiment, it is possible to calculate the genuine note area for a counterfeit note or a counterfeit note obtained by bonding genuine note notes of different denominations. In the first and second embodiments, the true / false line sensor is shown as a magnetic line sensor. However, banknotes such as a fluorescent line sensor and a phosphorescent line sensor can be used. As long as it is a sensor that detects the security information, the authenticity may be determined using the optical pattern of the optical line sensor. A plurality of sensors may be combined and used as a true / false sensor.

  The outline line sensor calculates the outline area of the bill, such as a line sensor that detects the amount of light transmitted through the paper sheet, a sensor that detects the amount of reflected light from the paper sheet, and a sensor that detects the amount of displacement of the paper sheet. Various known sensors can be used if possible.

  In addition, the true / false line sensor can detect the authenticity of a bill, such as a sensor for detecting the fluorescent component of a bill, a sensor for detecting a phosphorescent component of a bill, and a sensor for detecting a magnetic component of a bill as described above. For example, various conventionally known sensors can be used. Further, the true / false sensor is not limited to a single sensor, and a plurality of sensors may be used in combination.

  Also, a paper sheet processing apparatus such as a paper sheet sorting apparatus has a plurality of collection units, and is different based on the value of the paper sheets calculated in the first embodiment and the second embodiment. The structure conveyed to a collection | recovery part may be sufficient. In this case, a value obtained by summing the values of the sheets conveyed to each collection unit or a plurality of collection units may be calculated and output to the outside by a method such as display. Thereby, an attendant or the like can recognize the value of the paper sheets stored in the collection unit.
