Description

  The present invention relates to a paper sheet processing apparatus and a paper sheet processing method for sorting and processing paper sheets such as postal items in which addressee information such as name and the like is described together with address information.

  Conventionally, a sorting apparatus sorts a paper sheet by recognizing address information written on the paper sheet. For postal items with address information that has moved, such as moving, the clerk determines whether the person is moving out or moving in based on the name information of the addressee. In addition, a staff member who judges that the mail is addressed to the transferee writes the address of the new address by handwriting or affixes a label on which the address of the new address is printed. In order to automate such work, in recent years, a classification system has been proposed in which information related to the transferee (transferee) is registered in the destination information database in advance and the addressee is identified as a transferee or transferee by character recognition processing. Has been.

  However, in the character recognition process that simply calculates the similarity with the characters in the dictionary, there is a possibility that the character string of the transferred person and the character string of the transferred person are erroneously recognized. That is, it is not easy to reliably determine whether the addressee is a transferee or a transferee only by a general character recognition process based on only the similarity of each character. For this reason, in the sorting process for paper sheets including paper sheets addressed to the relocation person, there are problems such as support for reliable confirmation of the destination information by the human system or improvement in identification accuracy of the relocation person and the relocation person. .

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram schematically showing a configuration example of a sorting apparatus (sorting system) 1 as a paper sheet processing apparatus according to an embodiment of the present invention.
The sorting apparatus 1 sorts a delivery item such as a paper sheet or an article based on sorting information such as destination information including address information. That is, the sorting device 1 functions as a paper sheet processing device. In the present embodiment, the sorting device 1 as a paper sheet processing device sorts paper sheets by district or sorts in order of delivery based on destination information including address information and addressee information. An explanation will be given assuming this.

  The address information includes information indicating the area (for example, prefectures and municipalities), information indicating the area within the area (for example, a block), and information indicating the location (location) within the area (for example, The addressee information is assumed to be information (for example, a person name, a company name, or a company name) indicating the addressee person.

Next, the configuration of the sorting apparatus 1 will be described.
As shown in FIG. 1, the sorting apparatus 1 includes a sorting apparatus body 4, a video coding system (VCS) unit 5, and a destination information database (destination DB) 6.
As shown in FIG. 1, the sorting apparatus body 4 includes a control unit 11, a supply unit 12, a transport unit 13, a scanner 14, a barcode reader (BCR) 15, a label pasting unit 16, an ID code printing unit 17, and a destination code. A printing unit 18, a sorting unit 19, a stacking unit 20, and the like are included.

  The control unit 11 controls the entire sorting apparatus body 4. The control unit 11 includes a CPU, various memories, various interfaces, and the like. For example, the control unit 11 realizes control of each unit by the CPU executing a program stored in the memory. In addition, the control unit 11 is provided with a determination unit 21 for determining the address information of the paper sheet. Further, the determination unit 21 includes a character recognition unit (online OCR) 22 that recognizes destination information as character information from an image.

The supply unit 12 takes out paper sheets (for example, postal items) to be classified set by an operator one by one and supplies them to the transport unit 13. The said conveyance part 13 conveys the paper sheet taken out by the said supply part 12 by the said conveyance path 13a to each part of a back | latter stage.
The scanner 14 is installed downstream of the supply unit 12 with respect to the conveyance direction of the paper sheets by the conveyance unit 13. The scanner 14 reads an image of a surface on which address information is recorded as sorting information on a paper sheet taken out by the supply unit 12 and conveyed on the conveyance path 13a by the conveyance unit 13. is there. The bar code reader 15 reads bar code information such as an address code and an ID code printed on a paper sheet.

  The label sticking unit 16 is a module for sticking a label on a paper sheet. The label affixing unit 16 affixes a label on which correct destination information is printed on paper sheets with incorrect destination information. For example, the label affixing unit 16 affixes a label on which address information including address information of a new address (relocation destination) is printed to a paper sheet addressed to a person whose address has been changed due to a new address.

  The ID code printing unit 17 serves as an identification code for identifying the paper sheet (or the image of the paper sheet read by the scanner 14) with respect to the paper sheet to which no barcode is assigned. An ID code is printed. The destination code printing unit 18 prints barcode information (destination code) indicating the destination information described on the paper sheet. In the destination code printing unit 18, for example, based on the destination information determined by the determination unit 21 or the destination information input by the information input device 32, the destination code indicating the destination (classification destination) To print.

  The sorting unit 19 sorts each paper sheet based on the destination information. The stacking unit 20 stacks the paper sheets sorted by the sorting unit 19. The stacking unit 20 has a stacker for stacking paper sheets and a plurality of sorting pockets (not shown). Each sorting pocket is associated with a sorting destination as destination information. In other words, the paper sheets for which the destination information is determined are accumulated in the sorting pockets associated with the sorting destination indicated by the destination information.

  The stacking unit 20 includes a VCS stacker (hereinafter referred to as a VCS stacker) for stacking paper sheets for which destination information could not be determined as paper sheets to be processed by the VCS unit 5. . Among the paper sheets whose destination information could not be determined, the paper sheets to be processed by the VCS unit 5 are accumulated in the VCS stacker in the stacking unit 20.

  Further, the stacking unit 20 serves as a stacker for destinationless paper sheets (hereinafter referred to as a destinationless stacker) for stacking paper sheets for which there is no sorting pocket associated with the confirmed destination information. Have. Here, it is assumed that any sort pocket is associated with the address information registered in the destination information database 6. In addition, paper sheets to be transferred to the relocation destination (paper sheets addressed to the transferee) may be accumulated in the classification pocket corresponding to the address information of the relocation destination, or a dedicated classification pocket (addressed to the transferee). A sorting pocket for paper sheets) may be set.

  The discriminating unit 21 discriminates the sorting destination based on the destination information of each paper sheet. For example, the determination unit 21 recognizes the address information from the image of the paper sheet read by the scanner 14 by the character recognition unit 22, and determines the sorting destination of each paper sheet based on the recognized address information. For the paper sheet on which the ID code is printed, the address information corresponding to the ID code is read, and the sorting destination of the paper sheet is determined based on the address information. The discriminating unit 21 discriminates a classification destination from address information recognized by character recognition from an image of a paper sheet according to an operation mode set in advance by an operator or the like, or address information corresponding to an ID code. The sorting destination may be determined based on the above.

  The determination unit 21 recognizes destination information using a character recognition unit (online OCR) 22. The character recognition unit 22 recognizes character information as destination information from an image of a paper sheet read by the scanner 14. The character recognition unit 22 has a function of detecting a description area of the destination information and recognizing address information and addressee information included in the destination information. The determination unit 21 determines the destination information given to the paper based on the recognition result by the character recognition unit 22 and the information stored in the destination DB 6. For example, the determination unit 21 determines whether or not the recognition result is likely as address information based on whether or not the address information as the recognition result by the character recognition unit 22 matches the address information stored in the destination DB 6. Or whether the address information of the recognition result matches the address information of the transfer information (address information with a transferee).

  Further, since the character recognition unit 22 of the determination unit 21 functions as an online OCR, the processing time (recognition processing for performing character recognition (address information recognition processing) according to the transport time of the paper sheets in the sorting apparatus body 4). Processing time) is set. That is, the character recognition unit 22 can obtain the recognition result of the character information as address information within the recognition processing time (for example, the time from passing through the scanner 14 to the destination code printing unit 18). It consists of an algorithm. Further, the control unit 11 is configured to transfer an image of a paper sheet whose address information could not be recognized by the character recognition unit 22 to the information storage / distribution unit 31.

  The destination information database (destination DB) 6 stores destination information that exists as a destination (partition destination). That is, the determination unit 21 determines whether the result of the character recognition process by the character recognition unit 22 is correct based on the destination information stored in the destination information database 6. The destination information database 6 is appropriately updated when the destination person is changed or when a new destination is set.

  Further, when a person of certain address information moves, that is, when the addressee corresponding to the address information is changed, the address information database 6 includes transfer information including address information of the transferee's transfer destination. It is stored in the destination information database 6. The transfer information is associated with the address information. When the address information as the recognition result matches the address information of the transfer information, it is determined whether the addressee has moved out (transferred person) or a newly transferred addressee (transferred person). When the addressee of the address information is an addressee who has moved, it is determined that the address information of the paper sheet should be changed to the address information of the address based on the transfer information.

Next, the configuration of the VCS (video coding system) unit 5 will be described.
As shown in FIG. 1, the VCS unit 5 includes an information storage / distribution unit 31 and a plurality of information input devices (video coding disc: VCD) 32 (32a, 32b,...). Further, the VCS unit 5 may be provided with an offline OCR that performs character recognition as destination information using an algorithm different from that of the character recognition unit (online OCR) 22 in parallel with the information input device 32.
The information storage / distribution unit 31 functions as an interface between the sorting device body 4 and each information input device 32. Note that the information storage / distribution unit 31 may perform data communication with another sorting apparatus or access the destination information database 6 via a server apparatus (not shown).

  The information accumulation / distribution unit 31 accumulates information (video coding information) such as an image of a paper sheet that is determined by the determination unit 21 that address information could not be recognized. For example, the information storage / distribution unit 31 associates the ID information (ID code) assigned to the paper sheet with the image of the paper sheet and the character recognition result as address information by the character recognition unit 22. Is accumulated. Also, the information storage / distribution unit 31 stores information for video coding (hereinafter referred to as coding data) composed of paper sheet images and character recognition results associated with the ID information for each copy. The information is distributed to the information input device 32.

  The information input device 32 (32a, 32b,...) Functions as a teaching device that teaches destination information. The information input devices 32 (32a, 32b,...) Are devices in which an operator inputs destination information based on coding data including images of paper sheets distributed from the information storage / distribution unit 31, respectively. In one sorting system, a plurality of information input devices 32 are connected to the information storage / distribution unit 31. Each information input device 32 notifies the information storage / distribution unit 31 of the processing status and the like, and the address information input operation is performed based on the coding data distributed from the information storage / distribution unit 31 according to the notified processing status. Do. Further, information input by the operator using each information input device 32 is stored in the information storage / distribution unit 31.

  Moreover, each information input device 32 is comprised by the computer which has a control part, a memory | storage part, a display part, an operation part etc., for example. In each information input device 32, an image of the paper sheet in the coding data received from the information storage / distribution unit 31 is displayed on the display unit, and the address information by the operator or the like is displayed on the display unit. Accept input. Further, each information input device 32 transfers the input information input as address information by the operator to the information storage / distribution unit 31 as processed data (coded information) associated with the ID code of the paper sheet. It is like that.

  The information storage / distribution unit 31 also has a function of storing the information input by the information input device 32. The data input by the information input device 32 stored in the information storage / distribution unit 31 is appropriately supplied to the sorting device body 4. As a result, the sorting apparatus body 4 sorts the sheets based on the data processed by the VCS unit 5 (address information corresponding to the ID code) stored in the information storage / distribution unit 31. ing. That is, for a paper sheet whose address information has been input by the information input device 32, the sorting apparatus body 4 reads the ID code assigned to the paper sheet, and the paper sheet corresponding to the ID code. Address information (input information) is acquired from the information storage / distribution unit 31 and classified based on the acquired address information.

  In the following embodiments, description will be given of a processing example for efficiently performing a sorting process for a destination whose destination information has been changed by moving or the like in the sorting apparatus configured as described above. Here, it is assumed that the information regarding the destination whose address information has been changed due to moving or the like is managed as transfer information. In the form described below, transfer information is stored in the destination information database 6.

First, a first processing example will be described.
The first processing example is a process of attaching a label describing the new address information of the addressee based on the transfer information to the paper sheet addressed to the addressee to whom the sorting apparatus 1 has moved. Here, in addition to the corresponding address information, the transfer information includes addressee information such as the name of the transferee and address information of the transferee as information about the transferee, and the transferee to the address as information about the transferee If there is, the addressee information such as the name of the transferee is included. The addressee information is information other than address information such as the name of the addressee included in the address information.

  The paper sheets on which the address information registered as the transfer information is described can be processed manually by the operator or based on the addressee information obtained as a result of character recognition. Whether it is addressed to a transferee (currently not the address) or a transferee (current resident of the address) is determined by addressee information included in the address information written on the paper sheet. That is, when processing the paper sheet of the transfer information based on the character recognition result, the character recognition unit 22 needs to determine whether the destination person information included in the destination information is a transferee or a transferee. When determining whether the addressee information is a transferee or a transferee by character recognition, the character recognition unit 22 matches the addressee information such as the name included in the character recognition result of the destination information with the transferee or the transferee. Judge whether to do. When it is determined that the person is a transferee, the sorting device 1 attaches a label that describes the address of the transferee to the paper sheet.

  However, erroneous recognition may occur in the character recognition processing by the character recognition unit (OCR) 22 mounted on the sorting apparatus 1. For example, even for a paper sheet in which the name of the transferee is described as the addressee information, the character recognition unit 22 may determine that the addressee information is the name of the transferee. In addition, if a label describing the transferee's destination information is attached to an area on the paper sheet where the destination information is described, a person can visually recognize the destination information originally written on the paper sheet. Cannot be done (a human being cannot confirm that it was a misrecognition).

  That is, if a label is randomly attached or a label is always attached at a predetermined position, the destination information described on the paper sheet may not be visible. For this reason, in the present sorting apparatus 1, when a label for the transferee is pasted, the label is stuck so as not to hide the destination information described in the paper. Thereby, a person such as a deliveryman can surely confirm the destination information described on the paper sheet.

Next, the flow of the first processing example as described above will be described.
FIG. 2 is a flowchart for schematically explaining the flow of the first processing example.
First, in the sorting apparatus 1, paper sheets set in the supply unit 12 are taken out one by one and conveyed by the conveyance unit 13. The scanner 14 reads an image on the paper sheet transported by the transport unit 13 (step S11). The image read by the scanner 14 is supplied to the character recognition unit 22 in the control unit 11. The character recognition unit 22 performs character recognition processing for recognizing character information as destination information from the image read by the scanner 14 (step S12). However, for paper sheets on which a barcode is printed, the barcode reader 15 recognizes destination information indicated by the barcode.

  In the character recognition process, the character recognition unit 22 detects an area that is likely to be a destination information description area from the image read by the scanner 14 (area detection). In this area detection process, the character recognition unit 22 also detects whether or not a label is attached to the paper sheet. When the label is affixed, the character recognition unit 22 detects the character area in the area on the label as a description area of the destination information.

  When the address information description area is detected, the character recognition unit 22 detects a character string from the detected area (character string detection). When the character string is detected, the character recognition unit 22 detects each character from the detected character string (character detection). When each character is detected, the character recognizing unit 22 calculates a similarity between each detected character and each character registered in a character dictionary (not shown), whereby each character is similar (character candidate). To extract. As the character candidates, for example, a predetermined number of character candidates are selected in the order of similarity. When such a character candidate is selected, the character recognition unit 22 selects a word candidate that includes a combination of character candidates for each character and destination information (address information, addressee information) stored in the destination information database. The address information (address information and addressee information) is determined as a character recognition result.

  Note that when the paper sheets other than the transferee are classified according to the address information, in the character recognition process by the character recognition unit 22, only the address information included in the destination information may be recognized first. . In this case, if the address information as the recognition result matches the address information of the transfer information, the character recognition unit 22 may further perform a process of recognizing the addressee information included in the address information.

  When the recognition result of the destination information by the character recognition unit 22 is obtained, the determination unit 21 determines whether or not the obtained destination information is destination information addressed to the transferee (step S13). The determination unit 21 determines whether or not the paper sheet is addressed to the transferee by comparing the destination information of the recognition result and the transfer information registered in the destination DB 6. For example, the determination unit 21 determines whether the address information included in the destination information as the recognition result matches the address information of the transfer information registered in the destination DB 6. When the address information of the recognition result matches the address information of the transfer information, the determination unit 21 registers the destination person information (for example, the name of the destination person) included in the destination information as the recognition result in the destination DB 6. It is determined whether or not it matches the transferee information (for example, the name of the transferee) of the transfer information. When the addressee information of the recognition result matches the transferred person information, the determination unit 21 determines that the paper sheet is addressed to the transferred person.

  When it is determined that the paper sheet is not addressed to the transferee (step S13, NO), the determination unit 21 uses the destination information as the character recognition result obtained by the character recognition unit 22 as the destination information of the paper sheet. Determine as. When the destination information of the paper sheet is determined, the control unit 11 sorts the paper sheet based on the determined destination information. In this case, the control unit 11 prints the destination code indicating the destination information on the paper sheet by the destination code printing unit 18, and the sorting unit 19 puts the destination code in the sorting pocket in the stacking unit 20 corresponding to the destination information of the destination information. Accumulate. If the destination information cannot be recognized, the control unit 11 prints the ID code on the paper sheet by the ID code printing unit 17 and classifies the paper as a VCS paper sheet.

  When it is determined that the paper sheet is addressed to the transfer person (step S13, YES), the control unit 11 attaches a label printed with the transfer person information including the address information of the transfer destination to the paper sheet. I do. First, the control unit 11 determines whether or not the area described in the destination information in the paper sheet overlaps with a predetermined label application position (standard application position) on the paper sheet (step S15). In this case, the control unit 11 acquires, from the character recognition unit 22, the processing result obtained by the character detection processing region detection as information indicating the destination information description region in the paper sheet. Moreover, you may make it the label sticking part 16 perform the process of said step S15. In this case, the label sticking unit 16 may acquire information indicating the destination information description area obtained by the character recognition process via the control unit 11.

  If it is determined by the above determination that the address information description area and the standard pasting position do not overlap (NO in step S15), the control unit 11 prints the label on which the transfer person information is printed by the label pasting unit 16 on the paper. It pastes on the standard sticking position in the leaves (step S16). That is, the control unit 11 supplies information indicating the standard pasting position as information indicating the label pasting position to the label pasting unit 16 together with the transferee information as the classification information of the paper sheet. The label sticking unit 16 prints out transferee information on a label in an initial state stored in a storage unit (not shown), and sticks the label on which the transferer information is printed at a standard sticking position on the paper sheet.

  When the label printed with the transferred person information is attached to the paper sheet, the control unit 11 selects the paper sheet based on the transferred person information (address of the transferred address) printed on the label attached to the paper sheet. Partition (step S17). For example, the paper sheets to which the labels are attached may be classified based on the address information of the transfer destination, or may be accumulated in a predetermined classification pocket for the paper sheets to which the labels are attached. . As a result of such sorting processing, the paper sheet on which the label printed with the transferred person information is pasted so as not to overlap the destination information described in the paper sheet is classified into the sorting pocket corresponding to the moving-out destination or a predetermined number. It is divided into division pockets.

  If it is determined that the destination information description area and the standard pasting position overlap (step S15, YES), the control unit 11 selects another label pasting position different from the standard pasting position (step S18). Here, a label affixing position that does not overlap with the destination information description area is selected. Various methods can be applied to the method for selecting the label attaching position. For example, it may be possible to select a plurality of preset label pasting position candidates that do not overlap with the destination information description area, and whether or not the label pasting position can be secured based on the end of the destination information. May be determined.

  When the label pasting position that does not overlap with the address information description area on the paper sheet is selected (step S19, YES), the control unit 11 moves the label pasting position on the paper sheet to the selected label pasting position. A label on which the transferred person information is printed is pasted (step S20). For example, the control unit 11 supplies the label pasting unit 16 with information indicating the pasting position of the selected label together with the transferee information as the classification information of the paper sheet. The label sticking unit 16 prints out transferee information on a label in an initial state stored in a storage unit (not shown), and sticks a label on which the transferer information is printed to a selected label sticking position on the paper sheet. .

  When the label printed with the transferred person information is pasted on the paper sheet, the control unit 11 sorts based on the transferred person information (the address of the destination) printed on the label pasted on the paper sheet. Is performed (step S17). As a result of this sorting process, the paper sheets pasted so that the label on which the transferee information is printed do not overlap the destination information described in the paper sheets, It is divided into division pockets.

  Further, when it is determined that there is no label attaching position that does not overlap with the destination information description area on the paper sheet (step S19, NO), the control unit 11 cannot attach a label to the paper sheet. Judge that there is. When it is determined that the label cannot be attached to the paper sheet, the control unit 11 accumulates the paper sheets addressed to the transferee without attaching the label without attaching the label to the paper sheet. The paper sheet is sorted into the sorting pockets (step S21).

  As described above, in the first processing example, it is possible to reliably confirm the destination information described on the paper sheet by disabling the labeling that overlaps the destination information description area. In other words, in the first processing example, label sticking is prohibited unless a state where the originally described destination information is visible can be secured. For this reason, according to the first processing example, humans can surely confirm the paper sheets addressed to the transferee.

  Next, the example of the label sticking position selected by the said 1st process example is demonstrated.

  For example, FIG.3 and FIG.4 is a figure which shows the example of the sticking position of a label. FIG. 3A shows a state in which the destination information is described in the right area of the horizontally long paper sheet. Moreover, FIG.3 (b) has shown the state which affixed the label on the area | region on the left side in the paper sheets shown to Fig.3 (a). If the label affixing position shown in FIG. 3B is the standard affixing position, the paper sheets as shown in FIG. 3A do not overlap the destination information description area and the standard affixing position. A label is pasted at the standard pasting position.

  On the other hand, FIG. 4A shows a state in which the destination information is described in the left area of the horizontally long paper sheet. Moreover, FIG.4 (b) has shown the state which affixed the label on the area | region on the right side in the paper sheets shown to Fig.4 (a). If the label attachment position shown in FIG. 3 (b) is the standard attachment position, in the paper sheet shown in FIG. 4 (a), as shown by the dotted line in FIG. The description area and the standard pasting position overlap. For this reason, for paper sheets as shown in FIG. 4 (a), as shown in FIG. 4 (b), the label is attached to the right region of the paper sheet as a label application position other than the standard application position. A position is selected.

  In the first processing example as described above, the sorting apparatus determines whether or not the destination information described in the paper sheet is addressed to the transfer person based on the information of the transfer person registered in the database, and the paper sheet When it is determined that the destination information is addressed to the new addressee, a label printed with the information of the destination is pasted on the paper sheet so as not to overlap the address information description area. Further, the sorting device sorts a paper sheet into a predetermined sorting pocket without attaching a label if there is no area to which a label is attached without overlapping with a description area of destination information in the paper sheet. According to the first processing example as described above, it is possible to ensure that a person can visually recognize the destination information originally written on the paper sheet addressed to the transferee.

Next, a second processing example will be described.
The second process example is a process for improving the identification accuracy between the transferred person and the transferred person by the character recognition process as described above. As in the first processing example, when the address information included in the destination information obtained by OCR matches the address information of the transferee information, it is determined whether the sheet is addressed to the transferee or the transferee. Therefore, it is necessary to determine whether the destination information included in the destination information is a transferee or a transferee.

  For example, the addressee information included in the addressee information is determined by selecting one by comparing the similarity to the transferee information and the similarity to the transferee information. However, with simple character recognition, there is a possibility of misrecognizing the addressee information. The addressee information recognition process is a process for identifying whether the addressee is a transferee or a transferee. Therefore, it is considered that the recognition accuracy of the addressee information is improved in consideration of the tendency that the addressee becomes a transferee and the tendency to become a transferee.

FIG. 5 is a diagram illustrating an example of a change in time of a ratio of mails addressed to a transferee and mailings addressed to a transferee in a certain address information.
As shown in FIG. 5, the mail items addressed to the transferee generally decrease as time passes, and the mail items addressed to the transferee increase as time passes. Also, after a certain period of time, most of the mail is addressed to the transferee, and the mail addressed to the transferee is extremely small. It is considered that the recognition accuracy of the addressee information is improved by performing the addressee information identification process in consideration of such a tendency. That is, in the second processing example, in the addressee information recognition process, the time lapse information after the transferee's address information is registered as transfer information registered in the address information database is reflected in the recognition result. Thereby, in the 2nd processing example, misreading between a transferee and a transferee can be reduced.

Next, the flow of the second processing example will be described.
FIG. 6 is a flowchart showing a flow of destination information recognition processing according to the second processing example.
First, the image on the paper sheet read by the scanner 14 is input to the determination unit 21 in the control unit 11 (step S31). When a paper sheet image is input, the determination unit 21 first performs destination information recognition processing by the character recognition unit 22 (steps S32 to S36). The character recognition unit 22 first extracts a character area candidate that seems to be a destination information description area (step S32). The character recognition unit 22 extracts character line candidates from the extracted character region candidates (step S33). When the character region candidates are extracted, the character recognition unit 22 extracts character candidates for each character from the extracted character line candidates (step S34).

  When the character candidates are extracted, the character recognition unit 22 performs recognition processing on the extracted character candidates for each character (step S35). In the character candidate recognition process, a similarity is obtained for each character candidate. By combining the recognition results of these character candidates for each character, a destination information candidate is obtained. Here, first, it is assumed that the address information included in the destination information is to be recognized. When a destination information candidate (address information candidate) is obtained, the character recognition unit 22 collates the obtained address information candidate with each address information registered in the destination DB 6 (step S36). Thereby, the character recognition unit 22 specifies address information as the most likely destination information.

  When the most probable address information is specified, the determination unit 21 confirms whether the address information recognized by the character recognition unit 22 matches the address information included in the transfer information (step S37). When the address information recognized by the character recognition unit 22 does not match the address information of the transfer information (NO in step S37), the determination unit 21 uses the address information obtained in step S36 as the recognition result of the destination information of the paper sheet. To the control unit 11 (step S38).

  When it is confirmed that the address information recognized by the character recognition unit 22 matches the address information of the transfer information (step S37, YES), the determination unit 21 is detected from the image of the paper sheet by the character recognition unit 22. The recipient information included in the destination information is recognized (step S39). The addressee information is written on the paper as text information following the address information obtained in step S36. For this reason, the character recognition part 22 recognizes addressee information by recognizing the character information following address information. In the addressee information recognition process for the transfer information, it is determined whether the addressee is a transferee or a transferee. At this time, in the second processing example, the addressee information is recognized based on the recognition result weighted according to the elapsed time from the registration date and time of the transfer information. Such addressee recognition processing will be described in detail later.

  When it is recognized that the addressee is not a transferee by the addressee recognition process (step S40, NO), the determination unit 21 outputs the address information obtained in step S36 to the control unit 11 as the address information recognition result. (Step S38). Further, when the addressee recognizes that the addressee is a transferee by the addressee recognition process (step S40, YES), the determination unit 21 uses the current address information of the transferee included in the transfer information as the destination information. It outputs to the control part 11 as a recognition result (step S41).

  According to the processing as described above, with regard to paper sheets addressed to the transferee in which the address information before the transfer is described, the current address information (address information of the transfer destination) of the transferee read from the destination information database is Can be output as destination information for paper sheets.

Next, addressee recognition processing as a second processing example will be described.
FIG. 7 is a diagram illustrating an example of a recognition result for the addressee information. FIGS. 8A and 8B are diagrams showing examples of transfer information registered in the destination information database 6.
In the example shown in FIG. 7, it is assumed that the first character is an illegitimate character, the transferred person registered in the transfer information is “× Hontaro”, and the transferred person is “× Kitaro”. In the example shown in FIG. 7, for the second character, the first candidate is “tree” and the second candidate is “book”. As for the third character, the first candidate is “thick” and the second candidate is “dog”. In the fourth character, the first candidate is “Buro” and the second candidate is “Buro”.

  Here, the first candidate for each character is 10 points, and the second candidate is 5 points. However, as for the third character, neither the transferee nor the transferee includes the character “dog”. Therefore, the third character is the first candidate “thick”. Note that the first letter is also a first candidate of 10 points. Then, the total score for each character of the transferred person “× Hontaro” is 10 + 10 + 10 + 5 = 35 points, and the total score for each character of the transferred person “× Kitaro” is also 10 + 5 + 10 + 10 = 35 points.

  Further, in addition to the score for each character, a score is also set for each of the transferred person “× Taro” or the transferred person “× Kitaro”. For example, as shown in FIG. 8 (a), when the score for the transferred person “× Taro” is 10 points, the total score for the transferred person “× Taro” is 35 + 10 = 45 points. When the added points for the transferred person “× Kitaro” are 10 points, the total score for the transferred person “× Kitaro” is also 35 + 10 = 45 points.

  As in the above example, if the score for the transferee “× Taro” and the score for the transferee “× Kitaro” are the same, if the total score obtained from the recognition result for each character is the same, the transfer The total evaluation value (total score) for the person “× Taro” is the same as the total evaluation value (total score) for the person “× Kitaro”. In other words, even if the total score obtained from the recognition result for each character is the same, if the score for the transferred person “× Taro” differs from the transferred person ’s score for “× Kitaro”, “× Since there is a difference between the total evaluation value for “Taro” and the total evaluation value for “× Taro”, it is possible to determine whether the addressee information is a transferee or a transferee by comparing the total evaluation values of both.

  In the second processing example, the score for the transferred character string (for example, “× Hontaro”) and the score for the transferred character string (for example, “× Kitaro”) are always fixed points. Rather, it is changed according to the ratio of the paper sheets addressed to the transferee and the paper sheets addressed to the transferee. For example, if it is assumed that the paper sheet is a postal matter, the ratio of the paper sheet addressed to the transferee and the paper sheet addressed to the transferee changes with time as shown in FIG. In the example shown in FIG. 5, with the passage of time, the number of paper sheets addressed to the transferee decreases and the number of paper sheets addressed to the transferee increases. In such a case, according to the elapsed time from the time of registration of transfer information, it changes so that the score for a transferee's character string may be lowered and the score for a transferee's character string may be increased.

  For example, when 3 months have passed since the registration of the transfer information, as shown in FIG. 8 (b), 2 points are deducted from 10 points as a reference point for the transferee, and the score for the transferee is It is assumed that 2 points are added from 10 points as reference points. In this case, the score for the transferred person “× Taro” is 8 points, and the score for the transferred person “× Taro” is 12. In this case, the overall evaluation value for the transferee is 35 + 8 = 43 points, and the overall evaluation value for the transferee is 35 + 12 = 48 points.

  That is, if the total score obtained from the recognition result for each character of the addressee information is the same score for both the transferee and the transferee, the transferee will receive a score if the transfer information has passed 3 months from the time of registration. Therefore, it is determined that the addressee information is a transferee. Such discrimination results are not based solely on simple character recognition results, but are determined according to statistically assumed ratios of papers destined for the transferee and papers destined for the transferee. It is. That is, according to the second processing example, it can be expected that a highly accurate recognition result corresponding to not only the similarity of each character but also the tendency in the operation mode is obtained.

Next, the flow of addressee recognition processing will be described in detail as a second processing example.
FIG. 9 is a flowchart for explaining the flow of addressee recognition processing.
As described above, in the second processing example, for the character string of the transferred person and the character string of the transferred person included in the transfer information, a score corresponding to the elapsed time since the registration of the transfer information is obtained. Is set. In the second processing example described below, the score is determined according to a model (here, a graph as shown in FIG. 5 is assumed) that indicates the ratio of the paper sheets addressed to the transferee and the paper sheets addressed to the transferee. Shall be.

  First, in the process as shown in FIG. 6, it is assumed that the address information recognition result matches the address information of the transfer information. In this case, the discriminating unit 21 uses the character recognition unit 22 to calculate a score indicating the similarity between each character of the addressee information and each character of the transferred person and the transferred person included in the transfer information (step S50). Further, the determination unit 21 obtains the current date and time using a clock (not shown), and calculates an elapsed time from the registration date and time of the transfer information (step S51).

  When the elapsed time from the registration date and time is calculated, the determination unit 21 determines whether or not the elapsed time exceeds the valid period of the information regarding the transferee (step S52). For example, it is assumed that a certain period is set as the valid period of the information regarding the transferee. Such an effective period is a period for providing a service for sorting out by the original address to the transferee, and is set according to the operation mode. However, as in a fourth processing example to be described later, the validity of the information regarding the transferred person may be set according to the processing result without setting the predetermined effective period. In this case, the process of step S52 is omitted.

  When it is determined by the above determination that the elapsed time from the registration date and time has exceeded the valid period (step S52, YES), the determination unit 21 determines that the paper sheet is addressed to the transferee, and the transferee's Address information (address information obtained as a recognition result) is output to the control unit 11 (step S59). However, when the similarity between each character of the recipient information and each character of the transferee is low (that is, when the similarity between the entire addressee information and the transferee is low), the destination information of the paper is recognized. In order to process it as impossible, the determination unit 21 may output to the control unit 11 that the destination information cannot be recognized.

  Further, when it is determined by the above determination that the elapsed time from the registration date / time is within the valid period (step S <b> 52, NO), the determination unit 21 calculates the added points for the transferee and the transferee based on the calculated elapsed time. Calculate (step S53). The points added to the transferred person and the transferred person with respect to the elapsed time are calculated by a preset calculation model. As the predetermined calculation model, for example, a table indicating the score added to the transferee and the transferee corresponding to the elapsed time, or a calculation formula for calculating the score added to the transferee and the transferee by substituting the elapsed time, etc. Can be considered.

  When the score for the transferred person and the transferred person is calculated, the determination unit 21 adds the calculated score to the total score as a recognition result for each character (step S54). That is, the determination unit 21 adds the score for the transferee to the sum of the scores of each character of the transferee for each character in the addressee information (corresponding to the similarity for each character). This added score is used as a comprehensive evaluation value for the transferee. Further, the determination unit 21 adds the score of the transferred person to the value obtained by adding up the score of each character of the transferred person (corresponding to the similarity for each character) for each character in the addressee information. This added score is used as a comprehensive evaluation value for the transferee.

  When the comprehensive evaluation value for the transferred person and the transferred person is calculated, the determination unit 21 determines whether or not at least one of the comprehensive evaluation values for the transferred person and the transferred person is equal to or greater than a predetermined recognition threshold (step S55). If the overall evaluation value for the transferee and the overall evaluation value for the transferee are both less than the predetermined recognition threshold (NO in step S55), the determination unit 21 determines that the addressee information is neither a transferee nor a transferee. Determine. In this case, the determination unit 21 outputs to the control unit 11 that the addressee information cannot be recognized (step S56). Upon receiving this result, the control unit 11 performs processing for accumulating the paper sheets in the reject pocket.

  Moreover, when at least one of the comprehensive evaluation value for the transferee and the comprehensive evaluation value for the transferee is equal to or greater than a predetermined recognition threshold value (step S55, YES), the determination unit 21 determines the comprehensive evaluation value for the transferee. It is determined whether or not is higher than the comprehensive evaluation value for the transferred person (step S57). When it is determined by this determination that the overall evaluation value for the transferred person is higher than the overall evaluation value for the transferred person (step S57, YES), the determination unit 21 determines that the addressee information is the transferred person. In this case, the determination unit 21 outputs the current address information of the transferee (address information of the transfer destination) to the control unit 11 together with information indicating that the addressee is the transferee (step S58). In this case, the control unit 11 sorts the paper sheet based on the address information of the transfer destination.

  In addition, when it is determined by the above judgment that the overall evaluation value for the transferee is not higher than the overall evaluation value for the transferee (that is, the overall evaluation value for the transferee is higher than the overall evaluation value for the transferee, or When the comprehensive evaluation value for the same and the comprehensive evaluation value for the transferee are the same) (step S57, NO), the determination unit 21 determines that the addressee information is the transferee. In this case, the determination unit 21 outputs the address information of the transferee (address information obtained as a recognition result) to the control unit 11 (step S59). In this case, the control unit 11 sorts the paper sheet based on the address information obtained as a recognition result. Note that the determination unit 21 may notify the control unit 11 of information indicating that the destination person has been determined to be a transferee, as necessary.

Next, a third processing example will be described.
As described above, the sorting apparatus body 4 transmits the scanned image of the paper sheet whose address information could not be determined to the VCS unit 5. Further, the sorting apparatus main body 4 assigns an ID code to the paper sheets and accumulates them in the reject sorting pocket. The VCS unit 5 temporarily stores the image of the paper sheet supplied from the sorting apparatus body 4 in the information storage / distribution unit 31. The information storage / distribution unit 31 sequentially distributes the stored sheet images to the information input devices 32.

  Each information input device 32 looks at the image of the paper sheet displayed on the display unit, and a person (operator) inputs the destination information by keystroke. In general, the information input device 32 inputs address information included in the destination information from an image of a paper sheet as information necessary for the sorting process. For example, in the mail sorting process, the information input device 32 often has a keystroke input for only the postal code and block number assigned to the mail.

  As described above, the operator inputs address information based on the paper sheet image displayed on the display unit in the information input device 32. For this reason, in the information input device 32, even if the destination information described on the paper sheet is addressed to the transferee, the address information (address of the transferee) described on the paper sheet is key-input. . If the coding process (keystroke input) is completed in this state, the paper sheet addressed to the transferee is processed based on the address information of the transfer source (address information of the transferee).

  Therefore, as a third processing example, the information input device 32 checks whether the address information input by the operator by keystroke matches the address information of the transfer information registered in the destination DB 6. When the address input by key entry matches the address of the transfer information, the information input device 32 displays a warning message and prompts the user to select whether the person is a transferee or a transferee. As a result, the operator recognizes that the address information input by keystroke is transfer information, and further, it is necessary to select whether the addressee is a transferee or a transferee. When recognizing that the addressee needs to be selected, the operator selects either the transferee or the transferee as the addressee of the sheet based on the image of the sheet displayed on the display unit in the information input device 32. Select.

  The warning message may be anything that alerts the operator that the address information input by keystroke is transfer information. For example, the warning message may be blinking the display screen or generating a beep sound.

  In order to prompt the selection of the transferee and the transferee, the information input device 32 displays the name of the transferee and the name of the transferee registered as transfer information on the display unit in a selectable state. On the other hand, the operator selects either the transferred person or the transferred person displayed on the display unit. However, when it is determined that the addressee is neither a transferee nor a transferee, the information input device 32 may be configured to input a key indicating that the addressee is unknown or the address information is invalid.

  When the operator selects a transferee, the information input device 32 sends the address information (address information of the transfer destination) included in the transfer information and the paper sheet to the transferee instead of the address information input by the operator. Is output as a result of the coding process. When the operator selects a transferee, the information input device 32 outputs the address information input by the operator as a result of the coding process.

FIG. 10 is a diagram illustrating a display example when the address information of the transfer information is input by the information input device 32.
First, it is assumed that the operator has input the address information of the transfer information with the keyboard of the information input device 32. The information input device 32 accesses the destination DB 6 at the time when a key is input up to a block of address information, and checks whether there is address information of transfer information that matches the address information input by key input. When the address information input by key entry matches the address information of the transfer information, the information input device 32 displays a screen for prompting the selection of the addressee as shown in FIG. 10 on the display unit.

  In the example shown in FIG. 10, an image display column for paper sheets, a display column for input results, a warning message display column, and a selection column for addressees (transferrs and transferees) are displayed on the display unit. . In the image display field for paper sheets, images of paper sheets read by the scanner 14 are displayed. In the input result display field, address information input by the operator using the keyboard is displayed. In the warning message display field, guidance that the input address information matches the relocation information (that is, an address with a moving person) is displayed.

  That is, when the address information displayed in the display column of the input result matches the address information of the transfer information registered in the destination DB 6, a warning message display field indicating that the address is a moving person as described above Is displayed. In the addressee selection field, a selection field for selecting whether the addressee described on the paper sheet is a transferee or a transferee is displayed. In the display example shown in FIG. 10, “× Ki * ro” as a transferee and “○ Shiba × K” as a transferee are displayed in the display column of the addressee. The transferees and transferees displayed in the display column of the addressee can select with the mouse or the keyboard.

  In the display as shown in FIG. 10, the operator confirms the name of the addressee on the image of the paper sheet, and selects and designates a corresponding person from the persons displayed in the selection column with the mouse or the keyboard. Thereby, when the address information input by the operator is key-matched with the transfer information, the operator can confirm whether the addressee is a transferor or a transferee. Further, when the operator selects a transferee, the address information (address information of the transfer destination) included in the transfer information is output as a result of the coding process. As a result, the current address information can be obtained even when the addressee is a transferee.

Next, a fourth processing example will be described.
As described above, in postal items, the number of paper sheets addressed to the transferee decreases with the passage of time. In a general operation mode, mails are processed to transfer paper sheets addressed to the transferee to the address of the transferee during a predetermined transfer period. In this case, when the transfer period expires, the process for transferring the paper sheet addressed to the transferee is terminated. However, the method of reducing the number of paper sheets addressed to the transferee varies depending on the addressee. In other words, if the method of reducing the number of paper sheets addressed to the transferee differs for each addressee, it is efficient to set an appropriate period for each addressee as the transfer period for executing the transfer process based on the transfer information. it is conceivable that.

  Therefore, in the fourth processing example, the transfer information registered in the destination information database (destination DB) 6 is appropriately (periodically) adjusted. For example, in the fourth processing example, the determination result of the transferred person and the transferred person for each transfer information is accumulated, and each transfer information is adjusted according to the ratio of the transferred person and the transferred person in the actual determination result. To do. Here, for each address information of each transfer information, the number of paper sheets determined to be a transferee and the number of paper sheets determined to be a transferee are counted. In this case, when the number of paper sheets addressed to the transferee for a certain period falls below a predetermined threshold, the operator or administrator is prompted to delete the transfer information, or is automatically deleted from the destination DB 6 To do. Thereby, efficient management of the destination DB (transfer information) according to the actual processing status can be realized.

FIG. 11 is a diagram illustrating an example of transfer information in the destination information database 6.
In the example shown in FIG. 11, as each transfer information, the address information, the name of the resident (transferee), the name of the transferee (previous resident), the transfer date, the counter for the transferee (the number of mail items addressed to the transferee) ), Counters for transferees (number of mails addressed to transferees), etc. are registered. However, in the example illustrated in FIG. 11, not only destination information as transfer information in which information about a transferee is registered, but also destination information in which information about a transferee is not registered is shown.

  The name of the resident is information indicating the person who currently resides in the address information. When the destination information is transfer information, the name of the resident is the name of the transferee (current resident). The name of the transferee is information indicating a person who has previously lived in the address information. If the destination information is transfer information, the name of the transferee is not registered, and therefore it can be determined whether the destination information is transfer information based on whether the name of the transferee is registered. The transfer date is information indicating the date when the transferee moved out.

  The transferee counter indicates a value obtained by counting the number of paper sheets addressed to the transferee. When it is determined that the sheet of the address information is addressed to the transferee, the transferee counter is incremented (added by 1). The transferer counter indicates a value obtained by counting the number of paper sheets addressed to the transferee. When it is determined that the sheet of the address information is addressed to the transferee, the transferer counter is incremented (added by 1). The transferred-in counter and the transferred-out counter count the number of paper sheets addressed to the transferred person or the number of paper sheets addressed to the transferred person in a certain period. For this reason, the transferee counter and the transferee counter may be initialized every certain period, or may hold values counted every predetermined period (for example, one month). .

  In the fourth processing example, in transfer processing as shown in FIG. 11, in the sorting process for normal paper sheets, the numbers for the transferees and the numbers for the transferees are set as the transferee counter and the transferee counter. Count by. Thus, information indicating the number of persons transferred to and the number of persons transferred out in a predetermined period is registered in each transfer information.

  Further, in the fourth processing example, the transfer information is periodically adjusted in accordance with the ratio between the number of persons transferred to and the number of persons transferred. For example, if the ratio of the number of persons transferred to and the number of persons transferred is less than or equal to the reference value (threshold) for deleting the information of the transferred person, the information regarding the transferred person in the transfer information is deleted. Or a notification to delete the information on the transferee. In the configuration example shown in FIG. 11, deleting the information regarding the transferee also means changing the transfer information to normal destination information.

Next, the flow of the fourth processing example will be described.
FIG. 12 is a flowchart for explaining the flow of the paper sheet sorting process including the paper sheet counting process according to the fourth processing example.
First, in the sorting apparatus main body 4, the image of the paper sheet taken out from the supply unit 12 is read by the scanner 14 (step S61). The image read by the scanner 14 is supplied to the character recognition unit 22 in the control unit 11. The character recognition unit 22 performs a character recognition process for recognizing the address information included in the destination information from the image read by the scanner 14 (step S62). However, for paper sheets on which a barcode is printed, the barcode reader 15 recognizes destination information indicated by the barcode. The address information recognition process can be realized by the same process as the process described as the first or second process example.

  When the recognition result of the address information by the character recognition unit 22 is obtained, the determination unit 21 determines whether the address information as the recognition result matches the address information of the destination information (transfer information) where the transferee is registered. Is determined (step S63). When the address information of the recognition result matches the address information of the transfer information (step S63, YES), the determination unit 21 receives the addressee information included in the destination information described on the paper by the character recognition unit 22. A process of recognizing (for example, the name of the addressee) is performed (step S64). In this addressee recognition process, it is determined whether the addressee described on the paper sheet is a transferee or a transferee. The addressee recognition process can be realized by a process similar to the process described in the second process example.

  When it is recognized that the addressee described in the paper sheet is a transferee (step S65, YES), the determination unit 21 counts up a transferer counter in the transfer information (step S66). In this case, the determination unit 21 outputs the address information of the move-out destination of the transferee to the control unit 11 as a recognition result. Upon receiving such address information recognition result, the control unit 11 sorts the paper sheet based on the address information of the transfer destination (step S67).

  When the addressee described on the paper sheet is recognized as a transferee (step S65, NO), the determination unit 21 counts up a transferee counter in the transfer information (step S68). In this case, the determination unit 21 outputs the address information obtained by character recognition (the address of the transferee) to the control unit 11 as a recognition result. Upon receiving such address information recognition result, the control unit 11 sorts the paper sheet based on the address information of the transferee (step S69).

  According to the classification process of the fourth process example as described above, the number of persons destined for the transferee and the number of persons destined for the transferee are accumulated in each transfer information in the destination information database 6. Here, it is assumed that the number of transferees and the number of transferees within a predetermined period in each transfer information are counted up by the transferer counter and the transferer counter. The transfer information registered in the destination information database 6 is adjusted based on the value of the transferer counter and the value of the transferer counter as described above.

FIG. 13 is a flowchart for explaining the flow of destination information database adjustment processing according to the fourth processing example.
The control unit 11 of the sorting apparatus body 4 periodically adjusts the transfer information registered in the destination information database 6. When adjusting the transfer information, the control unit 11 searches the destination DB 6 for transfer information to be adjusted (step S71). When the transfer information to be adjusted is detected from the destination DB 6 (step S72, YES), the control unit 11 determines the number of paper sheets addressed to the transferee and the number of paper sheets addressed to the transferee in the transfer information. (Hereinafter referred to as the “addressee ratio”) is calculated (step S73). The ratio is calculated from the value of the transferee counter and the value of the transferee counter during a predetermined period.

  After calculating the addressee ratio, the control unit 11 determines whether the calculated addressee ratio is less than a predetermined deletion reference value for determining that the transfer information should be deleted (step S74). The deletion reference value is set according to the operation mode. For example, it is conceivable to set a value at which the number of transferees is about 1/5 of the number of transferees. Further, instead of the deletion reference value for the addressee ratio, a threshold value for the number addressed to the transferee may be set. In this case, it is possible to realize a mode in which the transfer information is determined as a deletion candidate if the number of transferees is less than a threshold value in a predetermined period.

  When it is determined by the above determination that the ratio is less than the deletion reference value (YES in step S74), the control unit 11 records the transfer information or information indicating the transferee as a deletion candidate in a memory (not shown) (step S75). ). When the transfer information is recorded as a deletion candidate in the memory, the control unit 11 returns to step S71 and performs a process of searching for the next transfer information from the destination DB 6. Further, when it is determined by the above determination that the ratio is equal to or greater than the deletion reference value (step S74, YES), the control unit 11 returns to the above step S71 without making the transfer information to be deleted, and moves to the next transfer information. Is searched from the destination DB 6.

  Further, when it is determined that there is no transfer information whose ratio is not confirmed in the destination DB 6, that is, when the destination person ratio in all transfer information registered in the destination DB is confirmed (step S72, NO), the control unit 11 Notifies the administrator or the operator of guidance to delete the transfer information recorded as the deletion candidate (step S76). The guidance for deleting the transfer information is notified to the manager or the operator by, for example, displaying it on a display unit in an operation panel (not shown). When such guidance is notified, the manager or the operator confirms the transfer information to be deleted and gives an instruction to delete the transfer information. In response to the delete instruction from the administrator or operator, the control unit 11 deletes the transfer information from the destination DB 6.

  Further, as the process of step S76, the control unit 11 may delete the transfer information recorded as the deletion candidate from the destination DB 6. In this case, the control unit 11 may further notify the administrator or the operator of the information indicating that the deletion has been performed. If the transfer information determined to be a deletion candidate is automatically deleted from the destination DB 6, the control unit 11 deletes the transfer information when it is determined that the transfer information is a deletion candidate in step S74. Anyway.

Since each of the first, second, third, and fourth processing examples as described above relates to processing for paper sheets addressed to a transferee, they can be implemented in combination.
For example, the first processing example is processing for attaching a label to a paper sheet addressed to a transferee. That is, the first processing example is related to the processing for the paper sheet addressed to the transferee, similarly to the second, third, and fourth processing examples. Therefore, the second, third, or fourth processing example. It is easy to carry out in combination, and it is considered that the effect of reliably processing the paper sheets addressed to the transferee is obtained by combining them.
