  If the determination unit cannot recognize the serial number, for example, the operator inputs the serial number recognized by the operator while visually confirming the display screen of the serial number reading result. The banknote handling apparatus stores the serial number input by the operator as a recognition result.

  For example, the discriminator can output a recognition result without operator intervention as a successful recognition when all the multi-digit numbers constituting the serial number can be recognized. When even one number cannot be recognized, operator intervention is required. The operator must input a multi-digit number correctly, and the burden on the operator is heavy.

  An object of the present invention is to provide a recognition support apparatus and a recognition support method that can reduce the burden on an operator.

  The recognition support apparatus according to the embodiment includes a recognition unit, a display unit, an input unit, and a generation unit. The recognition means recognizes each of a plurality of characters constituting the identification information. The display means displays a first recognition result of the first character in a first display format based on successful recognition of the first character included in the plurality of characters, and is included in the plurality of characters. Based on the recognition failure of the second character, the second recognition result of the second character is displayed in the second display format. The input means receives an input of a first designated character code corresponding to the second character with respect to the second recognition result. The generating means generates recognition results for the plurality of characters based on the first recognition result and the first designated character code.

  Hereinafter, embodiments will be described with reference to the drawings.

Drawing 1 is a figure showing an example of a bill processing system (recognition support device) concerning an embodiment.

  The banknote processing system includes a banknote processing apparatus main body 1 and a control device 2 for operating the banknote processing apparatus main body 1. The banknote processing apparatus main body 1 controlled by the control device 2 may be one or plural.

  The banknote handling apparatus main body 1 sorts banknotes (tickets) according to type or state, and sorts and stacks 1A for stacking the sorted banknotes by type or state, and a sealing apparatus 1B for sealing banknotes every predetermined number. And have. The banknote processing apparatus main body 1 is configured such that an arbitrary number of sealing apparatuses 1B can be connected to one sorting and accumulating apparatus 1A.

  In the sorting and accumulating apparatus 1A, a plurality of banknotes of a plurality of types are input in a lump. The sorting and accumulating device 1A sorts according to the type and state of each bill inserted. The sorting and stacking device 1A transports the sorted banknotes to each stacker (cassette) or sealing device 1B. The sealing device 1B accumulates the banknotes supplied from the sorting and accumulating device 1A in a stacker (cassette), and seals it with a paper band every predetermined number.

  The control device 2 performs control of the banknote processing apparatus body 1, operation setting for the banknote processing apparatus body 1, management of processing data by the banknote processing apparatus body 1, and the like. The control device 2 is constituted by a personal computer, for example. The control device 2 includes a display unit, an operation unit, a storage unit, and the like which will be described later.

  Next, the internal structure of the banknote processing apparatus main body 1 will be described.

  As shown in FIG. 1, the banknote processing apparatus main body 1 includes a sorting and accumulating apparatus 1A and a sealing apparatus 1B.

  The sorting and stacking apparatus 1A is provided with a loading unit 4 (unprocessed ticket storage unit) for loading a plurality of banknotes P. A plurality of bills in which a plurality of types are mixed are loaded into the loading unit 4 at once. The bills P inserted into the insertion unit 4 each have a longitudinal direction and a short direction. The insertion unit 4 is inserted in such a posture that the upper end or lower end in the longitudinal direction of the banknote faces downward.

  In addition, the banknote processing apparatus main body 1 of the banknote processing system shown to FIG. 1B hold | maintains a banknote in the state inclined about 40 degree | times with respect to the orthogonal | vertical direction.

  The input unit 4 includes a stage 5, a backup plate 6, and a take-out roller 10. A plurality of banknotes P are put into the stage 5 in a state where they are aligned with the upper end or the lower end thereof. The backup plate 6 is erected in the vertical direction with respect to the stage 5. The backup plate 6 is moved by the spring 8 along the stage 5 to the take-out roller 10 side (left direction in the figure). The take-out roller 10 is constituted by a pair of rollers. The take-out roller 10 sequentially takes out the bills P at the left end in the figure on the stage 5 by rotating in a predetermined direction. Accordingly, the plurality of banknotes P inserted into the insertion unit 4 are moved to the left in the drawing along the stage 5 by the backup plate 6 and pressed against the extraction roller 10 (extraction unit).

  A conveyance path 12 is provided at the subsequent stage of the take-out roller. The conveyance path 12 includes a plurality of rollers 15 and conveyance belts 14 and 16. In the transport path 12, the bills P are transported by transport belts 14 and 16 driven by a plurality of rollers 15. The banknotes P taken out by the take-out roller 10 are sequentially supplied to the transport path 12. For example, the take-out roller 10 supplies the banknote P to the transport path 12 in the short direction with its upper end or lower end at the top. Moreover, the banknote P supplied on the conveyance path 12 by the take-out roller 10 is in a state where the front and back sides are separated. In the configuration example shown in FIG. 1A, the banknote P taken out from the insertion unit 4 is directed downward.

  A detection unit 30 is provided on the conveyance path 12 extending downstream from the take-out roller 10. The detection unit 30 detects (discriminates) the characteristics of the banknote P, such as the type of bill, front and back, top and bottom, and the presence or absence of dirt or damage. The detection unit 30 includes various sensors. Various sensors provided in the detection unit 30 read various information from the banknotes P transported through the transport path 12. The detection unit 30 includes, for example, an image sensor that reads an image on the surface of the banknote P, a sensor that detects the thickness of the banknote P, a sensor that detects a magnetic body included in the banknote P, and the like. Based on the information read by each sensor of the detection unit 30, the determination unit described later determines the characteristics of the banknote P as described above.

  In the sorting and accumulating apparatus 1A shown in FIG. For this reason, each banknote P which passes the said detection part 30 is also in the state where the front and back and the top and bottom are scattered. Here, there are four types of orientations related to the front and back of the bill P passing through the detection unit 30 and the top and bottom. In the following description, the banknote P taken out with the surface facing upward and facing the upper end with respect to the front in the transport direction is referred to as a front (FF) note, and the front surface faces upward and the lower end with respect to the front in the transport direction. The banknote P withdrawn toward the front is referred to as a front (FR) ticket, the banknote P with the back facing upward and the top with respect to the front in the transport direction is referred to as a backside (BF) ticket, A banknote P that is taken upward and is directed toward the lower end with respect to the front in the transport direction is referred to as a back bottom (BR) ticket. That is, the banknote P conveyed through the detection unit 30 is conveyed in any one of these four types of conveyance attitudes.

  A plurality of gates G <b> 1 to G <b> 9 for selectively switching the conveyance direction of the banknotes P based on the detection result in the detection unit 30 are provided on the conveyance path 12 extended to the subsequent stage of the detection unit 30. .

  First, the gate G1 sorts the banknotes P into those that can be processed later and those that are rejected. For example, the banknote determined by the detection unit 30 to be incapable of subsequent processing is conveyed to the reject box 32 (rightward in the figure) via the gate G1. As banknotes that cannot be processed in the subsequent stage, for example, banknotes that have been determined to be picked up, banknotes that have been determined to have greatly skewed beyond a predetermined level, or genuine paper that can be recirculated have not been determined. There are banknotes (not necessarily banknotes) such as non-conformity tickets and counterfeits. The reject box 32 can be accessed from outside the sheet processing apparatus 1. That is, the banknote P accumulated in the reject box 32 can be taken out by an attendant.

  On the other hand, the banknote P determined by the detection unit 30 to be capable of subsequent processing is conveyed to the gate G2 (left direction in the figure) via the gate G1. The gate G2 sorts the banknotes P according to the front and back sides. The conveyance path on the downstream side of the gate G2 is branched in two directions. That is, the gate G2 selectively switches the conveyance direction of the banknote P to two directions according to the front and back state.

  On one conveyance path branched on the downstream side of the gate G2, a front / back reversing mechanism 34 (front / back reversing part) for reversing the front and back of the banknote P is provided. Moreover, the other conveyance path 36 branched on the downstream side of the gate G2 is a conveyance path that simply allows the banknote P to pass through without changing the front and back of the banknote P. That is, the front and back of the banknotes P can be arranged at the subsequent stage of the gate G2.

  The front / back reversing mechanism 34 is composed of two sets of conveying belts 33 and 35. The conveying belts 33 and 35 form a torsion conveying path rotated by 180 ° around the central axis from the inlet to the outlet. Therefore, the banknotes P distributed to the front / back reversing mechanism 34 by the gate G2 are reversed. For example, the FF ticket is reversed by the front / back reversing mechanism 34 and reversed to a BF ticket with the back side up.

  The banknote P that has been turned upside down by passing through the front / back reversing mechanism 34 and the banknote P that has passed through the transport path (transport path) 36 without passing through the front / back reversing mechanism 34 are both connected via the junction 38. It is sent to the gate G3.

  The processing time (conveyance time) of the banknote P from the gate G2 via the front / back reversing mechanism 34 to the junction 38 is the same as the conveyance time of the banknote P from the gate G2 via the conveyance path 36 to the junction 38. Is set to Thereby, the banknote P conveyed via the front / back reversing mechanism 34 and the banknote P passed through the conveyance path 36 pass through the junction 38 at the same timing.

  The gate G3 sorts the banknotes P that have passed through the junction 38. The conveyance path on the downstream side of the gate G3 is branched in two directions. The gate G3 selectively switches the conveyance direction of the bills P in two directions according to the type (or state) of the bills P.

  One conveyance path branched on the downstream side of the gate G3 is a conveyance path for conveying the banknote P to the sealing device 1B. Moreover, the other conveyance path (horizontal conveyance path) 40 branched on the downstream side of the gate G3 is a conveyance path for collecting the banknotes P in the respective stackers 41 to 46 in the sorting and stacking apparatus 1A. In addition, each of the stackers 41 to 46 is provided with a sensor that detects the presence or absence of banknotes.

  That is, the horizontal conveyance path 40 branched in the right direction in the figure by the gate G3 forms a conveyance path extending substantially in the horizontal direction above the plurality of stackers 41 to 46. On the horizontal conveyance path 40, five gates G <b> 5 to G <b> 9 for sorting and stacking the banknotes P into any one of the six stackers 41 to 46 are provided.

  The banknotes P selectively distributed by the gate G5 located on the most upstream side of the horizontal conveyance path 40 are accumulated in the accumulation box 41. The banknotes P selectively distributed by the gate G6 are accumulated in the accumulation box 42. The banknotes P selectively distributed by the gate G7 are accumulated in the accumulation box 43. The banknotes P selectively distributed by the gate G8 are accumulated in the accumulation box 44. The banknotes P selectively distributed by the gate G9 are accumulated in the accumulation box 45 or the accumulation box 46.

  As shown in FIG. 1A, the sealing device 1B includes a stacker 51, a stacker 52, a supply unit 53, a sealing mechanism 54, a printing mechanism 55, and a belt supply unit 56. The accumulation boxes 51 and 52 accumulate the banknotes P sent through the gate G4. Each stacker 51, 52 is provided with a sensor for detecting the presence or absence of banknotes.

  The supply unit 53 supplies a predetermined number (for example, 100) of banknotes P stacked in the stacker 51 or 52 to the sealing mechanism 54. The sealing mechanism 54 is a sealing mechanism that seals a predetermined number (for example, 100) of banknotes P stacked in the stacker 51 or 52 supplied by the supply unit 53 with a paper band. The printing mechanism 55 prints desired print data on a paper band used by the sealing mechanism 54. The band supply unit 56 supplies a paper band used in the sealing mechanism 54.

  The banknotes P are supplied to the sealing device 1B through a conveyance path branched leftward in the drawing by the gate G3 of the sorting and stacking device 1A. The banknotes P supplied from the sorting and accumulating apparatus 1A are selectively switched between two conveying directions by the gate G4 in the sealing apparatus 1B. The banknotes P branched and conveyed by the gate G4 are selectively stacked in the stacker 51 or the stacker 52 in the sealing device 1B.

  The bills P accumulated in any of the stacks 51 or 52 through the gate G4 are sent to the sealing mechanism 54 by the supply unit 53. In the sealing mechanism 54, a predetermined number of banknotes P supplied by the supply unit 53 are sealed with a paper band supplied from the band supply unit 56. A bundle of banknotes P sealed every predetermined number is carried out of the apparatus via a conveyor (not shown).

  In the sorting and accumulating apparatus 1A, a specific ticket type is supplied to the sealing apparatus 1B based on settings described later. Therefore, in the sealing device 1B, a bill of a specific bill type supplied by the sorting and accumulating device 1A is sealed. Moreover, the banknotes P of ticket types other than the ticket types to be sealed by the sealing device 1B are stacked in any of the stackers 41 to 46 in the sorting and stacking device 1A.

  Next, the control system of the paper sheet processing system will be described.

  FIG. 2 is a block diagram of a control system of the banknote processing system.

  As shown in FIG. 2, the control system of the sorting and stacking apparatus 1A of the banknote processing apparatus body 1 includes a control unit 60, a storage unit 61, a take-out control unit 62, a transport control unit 63, a gate control unit 64, a determination unit 65, and the like. It is comprised by.

  The control unit 60 controls the overall operation of the sorting and accumulating apparatus 1A according to a preset operation program. The storage unit 61 stores an operation program executed by the control unit 60. The storage unit 61 is used for storing data. For example, the storage unit 61 is provided with a counting table that counts the number of stacks stacked in the stacks 41 to 46 and the stacks 51 and 52 of the sealing device 1B.

  The take-out control unit 62 drives the take-out roller 10 based on the control of the control unit 60. The conveyance control unit 63 drives the conveyance rollers 15 based on the control of the control unit 60. The gate control unit 64 drives the gates G1 to G3 and G5 to G9 based on the control of the control unit 60.

  The determination unit 65 determines the state of the banknote P based on the detection result of the detection unit 30. The determination unit 65 determines the feature of the banknote P by comparing information read by each sensor with reference information. The determination unit 65 outputs a determination result based on the detection result of the detection unit 30 to the control unit 60.

  For example, the determination unit 65 determines the bill type of the banknote P and determines the front and back and the top and bottom of the banknote P. Further, the determination unit 65 determines whether the banknote P is a genuine note or a damaged note. A regular ticket is a ticket that can be recirculated, and a non-performing ticket is a ticket that cannot be recirculated. That is, whether it is a genuine note or a damaged note is determined based on whether the state (quality) of the bill is good or bad. The determination unit 65 determines whether the bill is a correct note or a damaged note based on the degree of dirt, tearing, folding, paper quality, tape sticking, or the like.

  As shown in FIG. 2, the control system of the sealing device 1B of the banknote processing apparatus main body 1 includes a control unit 70, a storage unit 71, a transport control unit 72, a gate control unit 73, a moving mechanism 74, a sealing mechanism 54, The printing mechanism 55 is used.

  The control unit 70 controls the overall operation of the sealing device 1B according to a preset operation program. The storage unit 71 stores an operation program executed by the control unit 70. The conveyance control unit 72 drives the conveyance roller based on the control of the control unit 70. The gate control unit 73 drives the gate G4 based on the control of the control unit 60. The moving mechanism 74 moves (conveys) a predetermined number of sheets stacked in the stacker 51 or 52 based on the control of the control unit 70.

  As shown in FIG. 2, the control system of the control device 2 includes a control unit 80, a storage unit 81, a display unit 82, an operation unit 83, a communication unit 84, and the like.

  The control unit 80 controls the entire control device 2 according to a preset operation program. For example, the control unit 80 has a function of performing various operation settings for the sorting and accumulating apparatus 1A based on operation instructions from the staff. The storage unit 81 stores an operation program executed by the control unit 80. The storage unit 81 stores setting information for the stacks 41 to 46 of the sorting and stacking apparatus 1A and the stacks 51 and 52 of the sealing apparatus 1B in correspondence with presets (setting names) described later. Is done.

  The display unit 82 displays operation guidance for the staff based on the display control of the control unit 80. The operation unit 83 is for an attendant to input an operation instruction. The display unit 82 includes a display device or the like. The operation unit 83 includes an input device such as a keyboard or a mouse. The display unit 82 and the operation unit 83 may be configured by a display device with a built-in touch panel, for example. Furthermore, the display unit 82 and the operation unit 83 may be configured to include a display device with a built-in touch panel and an input device such as a keyboard.

  The communication unit 84 communicates with the outside (for example, another banknote processing system), and receives processing amount data of each bill type (by banknote type) or circulation amount data of each bill type (by banknote type), which will be described later. can do.

  Next, the setting of the stacks (cassettes) 41 to 46, 51, and 52 of the sheet processing apparatus main body 1 by the control device 2 will be described.

  Here, it is assumed that the display unit 82 and the operation unit 83 are configured by a display device with a built-in touch panel. In addition, the setting of each of the storage boxes 41 to 46, 51, and 52 is performed by an administrator (supervisor).

  FIG. 3 is a flowchart for explaining the operation of displaying the cassette setting screen in the control device 2. FIG. 4 is a diagram illustrating a display example of a login screen. FIG. 5 is a diagram showing a display example of an administrator authentication screen. FIG. 6 is a diagram illustrating a display example of a menu screen for an administrator.

  First, the control unit 80 displays a login screen on the display unit 82 (step S1). For example, on the login screen, as shown in FIG. 4, selection buttons for a supervisor (an administrator who has authority to change settings, etc.) and an operator (an employee who does not have management authority) are displayed. When a button for selecting an administrator is input on such a login screen (step S2, YES), the control unit 80 displays the authentication screen of the administrator on the display unit 82 (step S3). For example, as shown in FIG. 5, the administrator authentication screen displays an input screen for the ID information and password of the administrator.

  When authentication information (ID information and password) is input on such a screen, the control unit 80 determines whether or not the input authentication information is correct (step S4). When it is determined that the authentication information input by this determination is correct (step S4, YES), the control unit 80 displays an administrator menu screen on the display unit 82 (step S5).

  For example, as shown in FIG. 6, a button for selecting at least cassette setting (cassette assignment) is displayed on the menu screen for the administrator. When a button for selecting a cassette setting is input on the menu screen for the administrator (step S6, YES), the control unit 80 displays a cassette assignment screen as described later on the display unit 82. (Step S7). On this cassette assignment screen, the setting of each cassette in the banknote processing apparatus main body 1 (setting of the condition of banknotes assigned to each cassette) is performed.

  As described above, the setting of each cassette or the setting of the damage level for distinguishing between a correct ticket and a damaged ticket can be performed only by an administrator who is authenticated by authentication information such as a password. That is, in the banknote processing system, banknotes are classified based on the setting contents set by the administrator. As a result, it is possible to prevent a general operator (person who does not have management authority) from changing the setting of each cassette or the setting of the damage level.

  Next, the setting screen of each stack (cassette) 41 to 46, 51, 52 will be described.

  FIG. 7 is a display example of a setting screen (cassette assignment screen) for each stack.

  In the display example shown in FIG. 7, the cassette assignment screen includes a setting status display window 101, a setting name display window 102, a read button 103, a storage button 104, ticket type designation buttons 111 to 117, status display icons 121 to 127, It includes a status designation button 130 (131 to 134), an add button 141, a delete button 142, an impairment level setting button 151, an Apply button 152, a paper band print setting button 153, a preset button 154, a return button 155, and the like.

  The display window 101 is a display area for displaying setting information of each stack. The display window 101 displays a list of bill types and conditions assigned to the stacks 41 to 46, 51, and 52. In the display example shown in FIG. 7, the leftmost column of the display window 101 displays information indicating the stack. For example, “S1-1” indicates the stacking box 51 of the sealing device 1B, and “S1-2” indicates the stacking box 52 of the sealing device 1B. Furthermore, “S2-1” to “S4-2” indicate the respective stackers of the second and subsequent sealing devices.

  FIG. 1 shows a configuration in which one sealing device is connected to the sorting / stacking device 1A. However, in the paper sheet processing system, as described above, one sorting / stacking device 1A is connected. It is possible to connect a plurality of sealing devices. When a plurality of sealing devices are connected to one sorting and accumulating device 1A, “S2-1” to “S4-2” indicate each stacker of the second and subsequent sealing devices.

  In the example of the display window 101 shown in FIG. 7, “A” in the leftmost column indicates the stacker 41 in the sorting / stacking apparatus 1A, and “B” indicates the stacking box 42 in the sorting / stacking apparatus 1A. . Here, in the display example shown in FIG. 7, two “A” columns are provided. This indicates that “A”, that is, two types of banknotes can be assigned to the stacking box 41. Thus, it is also possible to assign a plurality of types of banknotes to one stacker.

  In the second column from the left in the display window 101 of FIG. 7, information indicating the bill type of the banknote assigned to the corresponding stack is displayed. For example, in the example of the display window 101 shown in FIG. 7, “500 euro”, “A” is added to the cassette “S1-1” (that is, the stack 51) and the cassette “S1-1” (that is, the stack 51). "20 euros" is assigned to the cassette (that is, the storage 41), and "10 euros" is assigned to the cassette "B" (that is, the storage 42).

  In the example of the display window 101 shown in FIG. 7, the third column from the left displays information indicating the state of the banknote as the first condition for the banknote. In this column, information indicating a correct bill (Fit), a damaged ticket (Unfit), or a mixture of a correct ticket and a damaged ticket (Mix) is displayed as the first condition for the banknote.

  For example, in the example of the display window 101 shown in FIG. 7, the first condition is applied to the “S1-1” cassette (that is, the stack 51) and the “S1-1” cassette (that is, the stack 51). It shows that “500 euros” of “Mix” is allocated. Further, it is shown that “20 euros” of “mix of correct and non-performing bills (Mix)” is assigned to the cassette of “A” (that is, the stacking box 41). The “B” cassette (that is, the stacking box 42) is assigned with “10 euro” as the first condition “mix of correct and non-performing bills (Mix)”.

  In the fourth column from the left in the display window 101 of FIG. 7, information indicating the state of the banknote is displayed as the second condition for the banknote. In this column, as a second condition for banknotes, the banknote direction (direction when stacked in the stack) is the forward direction (Forward), the reverse direction (Backward), or the mixing of the forward direction and the reverse direction (Mix ) Is displayed. When the sorting and stacking apparatus 1A is provided with a mechanism for aligning the orientation, the display column indicating the orientation of the bills (the orientation when the bills are stacked in the stacker) is omitted.

  For example, in the example of the display window 101 shown in FIG. 7, the first condition is applied to the “S1-1” cassette (that is, the stack 51) and the “S1-1” cassette (that is, the stack 51). It shows that “500 euros” of “mixing of correct and non-performing bills (Mix)” and the second condition “mixing of normal and reverse directions (Mix)” is assigned. Further, in the cassette “A” (that is, the stacking box 41), the first condition is “mixed bill and non-slip bill (Mix)” and the second condition is “in the opposite direction to the forward direction”. It shows that “20 Euro” of “Mix (Mix)” is allocated. In the cassette “B” (that is, the stacking box 42), the first condition is “mixing of correct and non-performing bills (Mix)”, and the second condition is “mixing in the forward and reverse directions ( "Mix)" "10 euros" is assigned.

  The fifth column from the left (right end) in the display window 101 of FIG. 7 displays information indicating the damage level of the bill type of the banknote assigned to the corresponding stack. For example, in the example of the display window 101 shown in FIG. 7, it is shown that the level “5” is set as the damage level for each ticket type assigned to each cassette.

  The display window 102 is a display area for displaying a setting name called “preset”. The “preset” is a setting name for the entire setting contents as shown in FIG. The “preset” can be changed, for example, by clicking the right end of the display window 102.

  Details of the recognition support process will be described below.

  FIG. 10 is a flowchart illustrating an example of the recognition support process.

  The determination unit 65 of the sorting and stacking apparatus 1A processes the banknotes (paper sheets) being conveyed (S21) and transmits the processing result (S22). That is, the determination unit 65 reads the image of the banknote being conveyed, acquires image data corresponding to the banknote, detects a serial number area (identification information area) (see FIG. 13) from the image data, and detects the detected serial number. A plurality of character regions (see FIG. 13) are detected from the number region, a character is recognized from each of the detected plurality of character regions, and the image data and the recognition result are transmitted as processing results.

  The determination unit 65 outputs a recognition success recognition result when all characters constituting the serial number are recognized, and outputs a recognition failure recognition result when some characters are not recognized. .

  For example, recognition of a serial number composed of an 8-digit number and an alphabet will be described. Note that what is to be recognized in the present embodiment is not limited to numbers and alphabets, but may be symbols, for example. In this embodiment, the numbers, alphabets, and symbols to be recognized are collectively referred to as characters.

  FIG. 11A is a diagram illustrating an example of a recognition result format. FIG. 11B is a diagram for explaining the definition of the recognition result format.

  As shown in FIGS. 11A and 11B, the recognition information of digit 1 includes information (8) indicating successful recognition, and an image corresponding to the character code recognized from the image (A) of digit 1 or the image of digit 1 ( A). The recognition information of digit 2 includes information (0) indicating a recognition failure (no recognition candidate). The recognition information of digit 3 includes information (8) indicating successful recognition, and an image (C) of digit 3 or an image (C) corresponding to a character code recognized from the image of digit 3. The recognition information of the digit 4 includes information (8) indicating the recognition success and an image (1) corresponding to the character code recognized from the image (1) of the digit 4 or the image of the digit 4. The recognition information of digit 5 includes information (1) indicating recognition failure (number of recognition candidates 1) and an image (2) corresponding to the character code extracted from the image of digit 5 as a recognition candidate.

  The display unit 82 also recognizes the digit 5 recognition information (information (1) indicating recognition failure (number of recognition candidates 1) and an image (2) corresponding to the character code extracted as a recognition candidate from the digit 5 image). The character 5 recognition result is displayed in the third display format. For example, the display unit 82 displays the image (2) corresponding to the character code extracted as the recognition candidate from the image of the digit 5 in the fifth column (highlighted display column) corresponding to the digit 5 (for example, the display unit 82). Displays the background in white, the character in red, or the character blinks in black). The touch panel receives a confirmation input or a change input for the image (2) displayed in the fifth column displayed in the third display format.

  Further, the display unit 82 displays the recognition information of the digit 6 (information (8) indicating successful recognition and the image (3) of the digit 6 or the image (3) corresponding to the character code recognized from the image of the digit 6). Based on this, the recognition result of the digit 6 character is displayed in the first display format. For example, the display unit 82 displays the image (3) of the digit 6 or the image (3) corresponding to the character code recognized from the image of the digit 6 in the sixth column (non-highlighted display column) corresponding to the digit 6.

  Here, the display process of the screen shown in FIG. 13 will be described with reference to the flowchart shown in FIG.

  After the initial setting (i = 0), the control unit 80 repeats the following processing (S43 to S50) until the check of all the digits is completed (S41) (S42).

  First, when the digit Pi is recognized successfully (S43, YES), the control unit 80 inputs an image corresponding to the digit Pi into the display column of the digit Pi (S44). In this case, it is assumed that the image input in the display field cannot be corrected. As described above, the image corresponding to the digit Pi is the image of the digit Pi (the character area image of the digit Pi) or the image corresponding to the character code recognized from the image of the digit Pi (the image of the dictionary). ).

  When the digit Pi is a recognition failure (S43, NO) and there is no recognition candidate for the digit Pi (S45, NO), the control unit 80 makes the display column of the digit Pi blank (blank) (S46).

  When the digit Pi is a recognition failure (S43, NO) and there is one recognition candidate for the digit Pi (S45, YES) (S47, YES), the control unit 80 converts the recognition candidate image corresponding to the digit Pi to the digit Pi. Input to the display field (S48).

  When the digit Pi is a recognition failure (S43, NO) and there are a plurality of recognition candidates for the digit Pi (S45, YES) (S47, NO), the control unit 80 selects the digit among the plurality of recognition candidates corresponding to the digit Pi. The image of the recognition candidate most likely as the character of Pi is input to the display column of the digit Pi, and the other recognition candidate images are input to the selection column provided corresponding to the display column of the digit Pi (S49).

  Through the above processing, the display unit 82 can display the screen shown in FIG.

Judgment can be made.

  The operator can easily input the character of the digit that failed to be recognized while looking at the screen shown in FIG. 13 (S28). For example, when the operator touches the second column of the display unit 82 (touch panel) and touches a predetermined key on the keyboard on the display unit 82 (touch panel of the operation unit 83), the operation unit 83 controls the second column. The character (for example, B) corresponding to the predetermined key is input.

  Further, when the operator touches the fifth column of the display unit 82, the operation unit 83 determines the recognition candidate (2) displayed in the fifth column. Alternatively, when the operator continues to touch the fifth column of the display unit 82 for a predetermined time, the recognition candidate in the fifth column can be corrected, and when the operator touches a predetermined key on the keyboard on the display unit 82, the operation unit In 83, the character corresponding to the predetermined key is input to the fifth column.

  When the operator touches the eighth column of the display unit 82, the operation unit 83 determines the recognition candidate (6) displayed in the eighth column. Alternatively, when the operator touches the first display area displayed corresponding to the eighth column of the display unit 82, the operation unit 83 sets the recognition candidate (0) displayed in the first display area to the eighth display area. Fill in the fields and confirm. Alternatively, when the operator touches the second display area displayed corresponding to the eighth column of the display unit 82, the operation unit 83 sets the recognition candidate (8) displayed in the second display area as the eighth display area. Fill in the fields and confirm. Alternatively, when the operator continues to touch the eighth column of the display unit 82 for a predetermined time, the recognition candidate in the eighth column can be corrected, and when the operator touches a predetermined key on the keyboard on the display unit 82, the operation unit In 83, the character corresponding to the predetermined key is input to the eighth column.

  When all the digits are confirmed, the control unit 80 stores the processing result including the confirmed serial number data in the storage unit 81 (S29). In other words, the control unit 80 generates a final recognition result based on the character (recognition result) recognized by the determination unit 65 and the character confirmed, selected, or input by the operator, and stores it in the storage unit 81.

  Further, based on the final recognition result, the control unit 80 displays final information indicating which serial number of banknotes is stacked in which stacker and which serial number of banknotes is sealed with which sealing number. Generated and stored in the storage unit 81 (S30). With the final information, the banknotes in the banknote handling system can be tracked.

  In addition, when the serial number recognition of a plurality of banknotes fails, a plurality of files corresponding to the recognition failure are displayed, and the operator can select one file at a time and generate a final recognition result of each banknote.

  According to the present embodiment, the following effects can be obtained.

  With the above configuration, the banknote handling system of the present embodiment can minimize the input effort by the operator, reduce the operator's workload, and improve the processing efficiency. That is, the operator only has to input only the digits of recognition failure or select a candidate.
