Abstract

PROBLEM TO BE SOLVED: To enable mechanical sorting of a delivery goods by a sorter even to addresses which cannot be represented using a destination code having an upper limit to the code length. SOLUTION: An address code representing address information is assigned to a destination code which defines a different coding scheme from a routine one, using an escape code and the destination code to which the address code is assigned is defined as an alias code. In addition, an alias code table 305 is provided which stores a corresponding list between the alias code and the address code. For the address code 203 exceeding the upper limit of the code length, the destination code information generation 301 replaces a part or the entirety of an entered address code with its corresponding alias code, referring to the alias code table 305 and then outputs a destination code limited within the upper limit value of the code length. The destination bar code conversion 303 converts the entered destination code to bar code information. Consequently, even for the destination code having the upper limit to the code length, it is possible to represent the address code exceeding its upper limit of the code length and even for an address which cannot be represented by a conventional destination code, a delivery goods can be mechanically sorted out by the sorter.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an address recognition device for reading and interpreting address information written on paper, a barcode recognition device for reading and interpreting barcode information, and a delivery using the recognition device. The present invention relates to a sorting machine and a related delivery sorting system.

2. Description of the Related Art In a delivery sorting system, character information necessary for specifying an address, such as a street address, a building number, and a room number, is read by a sorting machine in addition to a street name of an address.
Classification is performed for each destination of the delivery. For delivery items that could not be read by the sorting machine, display the address image on the terminal,
By manually inputting the address information, the delivery is read using the sorting machine together with the delivery read by the sorting machine. A system for manually inputting address information while viewing an address image is a video coding system (hereinafter referred to as VCS).
). The address information on the delivery obtained through the sorting machine or manually is finally converted into a barcode representing the destination information, that is, a destination barcode, and printed on the delivery via the sorting machine. All subsequent processing is performed by reading the destination barcode. FIG. 1 shows an example of a delivery on which a destination barcode is printed. Ten
Reference numeral 2 denotes character information indicating an address, reference numeral 103 denotes a barcode indicating an ID for specifying a delivery, and reference numeral 104 denotes a destination barcode representing address information of the delivery.

The reason why the read address information is converted into a bar code and printed on a delivery is that the bar code reading stability is generally higher than the character information reading stability. On the other hand, the area where a barcode can be printed on a delivery on which character information such as an address is already written is limited. Therefore, it is necessary to represent address information using a barcode having a limited code length. As a result, the address information written on the delivery may not be within the upper limit of the bar code length in some areas. In this case, after the code in the portion exceeding the upper limit is deleted, it is converted into a barcode as a destination barcode and printed.
Then, the sorting machine performs sorting using information up to the upper limit code length. FIG. 2 shows a process of reading the address information on the delivery and converting it into barcode information.
In the address recognition and VCS input 202, the address information is extracted from the delivery by the address recognition by the sorting machine or the VCS input and output as the address code 203. In the destination code information generation 204, a portion of the address code exceeding the upper limit code length Lmax is deleted, and a destination code for printing a barcode is generated. In the destination barcode conversion 206, the destination code stored within the upper limit code length is converted into the destination barcode 207. When it is attempted to classify a delivery in detail using a sorting machine, in a region where address information cannot be expressed within the upper limit code length, the delivery cannot be correctly sorted, and the deliverer needs to re-sort the delivery. When there are few deliveries to be re-sorted, no great burden is imposed even if the delivery person manually sorts. However, in the case of a large apartment house such as a large-scale apartment complex, if it becomes impossible to classify using the building number, for example, a large number of deliveries destined for the complex will need to be re-sorted by the deliverer, and the burden on the deliverer will increase growing. In the case of FIG. 2, if the address code is deleted with Lmax, the destination code becomes "100000611".
-222-333-11 ". Here, if an address that is the same as" 100000611-222-333-11 "actually exists, it is misclassified to another destination. As a result, the manual re-sorting after the machine sorting may be more complicated, while there are methods for avoiding such a problem.First, an ID code for identifying a delivery is expressed. The ID bar code is printed on the delivery, and the data of the ID code and the address information are electronically sent to the delivery station of the destination, and the ID bar code of the delivery information is sent to the delivery station of the destination. With this method, it is possible to classify the destination bar code without being restricted by the code length of the destination bar code. Requires significant additional investment in equipment In addition, if the sender who sends out the delivery item converts the destination information into a sender barcode that also has an upper limit on the code length and prints it on the delivery item in advance, Since all the address information is not reflected in the code, it is necessary to perform the address recognition again in the sorting machine, and as a result, the merit of reading the pre-printed sender barcode to improve the sorting efficiency is reduced. An object of the present invention is to make it possible to correctly perform detailed sorting using a sorting machine even when address information on a delivery cannot be represented by a barcode having a limited code length, thereby saving labor in detailed sorting work.

DESCRIPTION OF THE PREFERRED EMBODIMENTS This embodiment will be described below. FIG. 3 shows a flow of processing for reading address information on a delivery and converting the read address information into destination barcode information. In the address recognition / VCS input 202, after inputting the address image 201, the address recognition device or the VCS
To obtain the address information on the delivery, and output the result as an address code 203. In the destination code information generation 301, as in FIG. 2, an address code 203 expressing a result of extracting address information on a delivery using a destination recognition device or a VCS is input. After that, if the input address code exceeds the maximum code length, replace part or all of the address code with the alias code,
Outputs the destination code expressed within the upper limit code length.
The upper limit code length of the destination code is, for example, 19 digits. 30
The process 1 will be described in detail with reference to FIGS. FIG. 4 is an example of an alias code table which is a correspondence table between an alias code and an address code. FIG. 5 is an example of a destination code expressed using an alias code. In FIG. 4, for example, the format of the address code 402 is defined such that a code indicating a street / address is written without a delimiter after a place name code specifying a place name. And the alias code 401 is
It is defined such that an escape code "-" for indicating an alias code follows the place name code, followed by a two-digit identification number of the alias code. Since "-" is not inserted between the place name code and the street / address in the ordinary address code, it is possible to easily determine that the code is an alias code. FIG. 5 shows an example of an address code expressed using the alias code of FIG.
The 23-digit address code of 502 can be expressed by a 16-digit code of 501, and can be contained within 19 digits of the upper limit code length. In the destination barcode conversion 303, the destination barcode information 3
Convert to 04. As described above, according to the processing described with reference to FIGS. 3, 4, and 5, it is possible to obtain the destination barcode information within the upper limit code long digit by using the alias code from the destination image. Although the final output in FIG. 3 is the destination barcode information, the destination code obtained as the preceding destination code can be stored in a file or the like. Next, a process of restoring the alias code included therein from the destination barcode printed on the delivery and acquiring the address code information as the sorting information will be described with reference to FIG. In the destination barcode recognition 602, the destination barcode image 601 on the delivery is recognized, and the destination code 6
Outputs 03. In the address code information acquisition 604, the recognized destination code 603 is input, and the alias code table 3
Restore the original address code with reference to 05. In this process,
After extracting the alias code included in the destination code, a search for an alias code that matches the alias code stored in the alias code table 305 is performed. After that, replace the address code corresponding to the searched code with the alias code included in the destination code, and replace the original address code
605 is restored and output. In the present embodiment, in order to determine whether the address code is an alias code or a conventional address code, "-" existing immediately after the place name code of the address code is used as an escape code. However, any method other than the present embodiment may be used as long as there is no inconvenience for distinguishing a normal address code from an alias code. For example, if it is known in advance that there is no alphabet at the beginning of the code representing the street or address, the alphabet character next to the place name code may be defined as an escape code. Furthermore, if the code representing the place name does not include an alphabet, any alphabet included in the place name code can be defined as an escape code. In this embodiment, an alias code is defined for a destination barcode printed by a sorting machine. However, it is possible to define an alias code for a sender barcode that the sender pre-prints on the delivery. The sender barcode is a barcode that represents address information of the recipient and has an upper limit in the code length similarly to the destination barcode. Conventionally, an address code exceeding the upper limit code length has been converted to a sender bar code by deleting an excess portion in the same manner as a destination bar code.
However, by making the alias code table shown in FIG. 4 publicly available, the sender can use the alias code. The sender registers these alias code tables in a word processor capable of printing a sender barcode via an electronic medium such as a floppy (registered trademark). Thereby, even when the address code exceeds the upper limit code length, the sender barcode can be printed without losing the address information.
On the other hand, in the sorting machine, after recognizing the sender's barcode including the alias code, the address code information restoration processing similar to that in FIG. 6 is performed. This makes it possible to sort the delivery on which the sender barcode is printed without losing the address information for sorting. FIG. 7 shows a schematic configuration of an apparatus equipped with an alias code table and for printing address information including a sender barcode on a delivery by referring to a database in which destination information is stored. A printing mechanism 700 includes a supply mechanism 702 for sequentially supplying a large number of deliverables 701 to the printing mechanism, and a printing mechanism 703. The printing mechanism 703 receives printing information from the database management computer 707,
Based on this, the address information is printed on the delivery. The print control computer 707 includes a destination information DB 711 in which destination information of a delivery is stored, an alias code table 705 in which an alias code and an address code are paired, and an electronic medium 706 in which information of the alias code table is stored.
Is connected. In the computer, an alias code registration / update unit 708 for registering / updating the alias code table 705 using the alias code table information stored in the electronic medium, a destination information DB 7
A destination code generation unit that generates a destination code using the alias code table from the destination information stored in 11
709, a barcode conversion unit 710 for converting a destination code into sender barcode information. With reference to the destination information in the destination information DB 711, an overall flow of printing destination information including a sender barcode on a delivery will be described. First, the information of the alias code table stored in the electronic medium 706 is registered in the alias code table 705 via the alias code registration / update unit 708. The destination code information generation unit 709 converts the address code information stored in the destination information DB 711 into a destination code with reference to the alias code table 705. Here, for an address code exceeding the upper limit value of the destination code length, the code conversion is performed using an alias code so that the code is within the upper limit value. The barcode information conversion unit 710 converts the generated destination code into barcode information. The print control computer 707 controls the print mechanism 703 using the generated barcode information and other address information. In this embodiment, the alias code table information for registering / updating the alias code table 705 is stored in an electronic medium, but information obtained through a network may be used. FIG. 8 shows a schematic configuration of a delivery sorting machine on which an address recognition device and a VCS are mounted and which performs conversion and restoration processing to an alias code. Reference numeral 800 denotes a main body (mechanical unit) of a delivery sorting machine, and a large number of delivery products 80
Supply mechanism 802 for sequentially supplying 1 to the scanner, and scanner 80
3, a transport mechanism 804 for transporting the scanned delivery to the sorting mechanism, and a printing mechanism 805 for printing an ID code for identifying the delivery and a destination code for specifying the sorting destination as a barcode. And a sorting mechanism 806 for receiving sorting information for determining a delivery destination of the delivery from the central control computer 816 and sorting the delivery. Further, the sorting mechanism 806 is provided with a plurality of control computers, and these computers control the entire mechanism 806 under instructions from a central control computer 816. The control computer 816 is connected with a sorting information management DB 815 for storing sorting information of the delivery and an alias code table 305, and reads and controls these pieces of information. This computer consists of three modules. Respectively,
A code conversion unit 819 that performs conversion from an address code to a destination code with reference to the alias code table 305,
A section information generation unit 817 that generates section information from the destination code with reference to the section information management DB 815, and a control information generation unit 818 that generates a control signal for controlling the generated section information by the section mechanism. Reference numeral 808 denotes a delivery recognition apparatus that inputs image data obtained by reading address information written on the delivery from the scanner 803 and executes various recognition processes. The present apparatus has a destination barcode reader 809 that reads an ID code and a destination code printed on a delivery to distinguish each delivery, and represents address information, and is printed on the delivery in advance by a sender. The sender bar code reader 810 reads a bar code, and an address recognition device 811 reads character information of an address image. 812 is a VCS,
When the address recognition device fails to recognize the address, the address information is input by the operator while looking at the address image, and the result is sent to the control computer. The system is an image handler (IH) 814 that manages the destination image, a destination image display terminal (VCD)
Consists of 813. The entire flow including the conversion / restoration processing to the alias code will be described with reference to FIG. When the delivery 801 is input to the sorting machine, the address image on the delivery is taken in via the scanner 803 and sent to the delivery recognition device 808. In the device, the image is first sent to the destination barcode reader 809. When the destination barcode reader 809 has already printed the destination barcode indicating the classification information, the destination barcode reader 809 reads the destination barcode and sends the recognition result to the control computer 813. If the destination barcode is not printed, the image is sent to the sender barcode reader 810 or the address recognition device 811. The sender bar code reader 810 reads the bar code printed by the sender, and sends the destination code, which is the recognition result, to the control computer 816. If the reading has failed, the recognition reject information is output to the VCS 812. After recognizing the input address image, the address recognition device 811 outputs the recognition result to the control computer 816 in the form of an address code. If the address recognition device fails in the recognition, it outputs the recognition reject information and the partially recognized result, if any, to the VCS 812. VCS8
At 12, the address image and the output of the address recognition device are received, and the address information is manually input while viewing the image. The entered address information is stored in the form of an address code in the control computer 816.
Is output to The control computer 816 converts the address code generated by the address recognition device 811 or the VCS 812 into destination barcode information stored within the upper limit of the code length by the processing procedure shown in FIG. The generated barcode information is printed on the delivery via the printing mechanism 805 in the form of a barcode. The address code is used as control information for controlling the sorting mechanism 806. On the other hand, the destination code output by the destination barcode reader 809 or the sender barcode reader is restored to the original address code according to the processing procedure of FIG. The control computer 813 controls the printing mechanism 805 based on the destination barcode information. On the other hand, the sorting mechanism 806 is controlled based on the original address code, not the destination barcode converted by the alias code table 305. Therefore, the sorting information management DB 814 stores the alias code table 8
It can be managed independently without depending on 15. As a result, even when the alias code is updated, only the alias code table 305 needs to be changed, and there is no need to change the sorting information management DB 815, so that system management does not become complicated. FIG. 9 shows an input screen for inputting a destination code represented by an alias code using the address database and the provided alias code table. In the configuration of FIG. 7, an address code is stored in an address database, and a destination code represented by an alias code is generated immediately before printing an address and a destination barcode on a delivery. On the other hand, it is also possible to store a destination code represented by an alias code in an address database in advance, and print a destination barcode on a delivery using the destination code. FIG. 9 shows an example of an input screen for inputting a destination code using an alias code for that purpose. 901 and 902 are a postal code and an address character string registered in the address database, respectively. An address / alias code table 904 stores the alias code searched using the postal code 901 and the corresponding address. Reference numeral 903 denotes an input field for inputting a destination code. 9
The flow of processing for inputting a destination code will be described with reference to 01, 902, and 904. First, search the address database to find the registered postal code and address string, respectively.
Display on 901 and 902. Next, the alias code table is searched using the zip code of 901. As a result, the alias code belonging to the postal code and the corresponding address are displayed in 904. The operator compares the address character strings of 904 and 902, and when determining that the address corresponding to the alias code is included in 902, selects the corresponding alias code using input means such as a mouse. 904
, The thick line indicates the selected state. The selected alias code is copied to 903. Then, the operator additionally inputs the destination code following the alias code, in the example of the figure, the room number “1102”. With the above processing, it is possible to input the destination code using the alias code.

As described above, according to the present invention, even when the address code exceeds the upper limit of the code length, the destination barcode can be expressed within the upper limit using the alias code, and the address information can be displayed. Can be sorted without impairing the delivery. In addition, the alias code may be defined only for the area where the address code exceeds the upper limit value or for the address, and the number is considered to be very small in view of the total number of addresses in the delivery target area. Since it is sufficient to share this small number of alias codes with other delivery stations, it is considered that there is almost no operational load due to the use of this method. Therefore, if the present invention is applied to a delivery classification system, it is possible to perform a classification without damaging the address information without significantly changing the current system. In particular, when the portion exceeding the upper limit corresponds to the ridge room number of the large-scale housing complex, the effect is enhanced. For example, if the address information of the ridge room number is missing, it is almost impossible to sort the deliveries in the order of delivery in the large-scale housing complex using the sorting machine. for that reason,
You need to manually sort large quantities of deliveries in order of delivery,
The advantage of the sorting machine cannot be used. By using the present invention, it is possible to sort the delivery order by machine even in such an area, so that efficient delivery can be performed.

An alias code search means for searching whether or not an address code corresponding to part or all of the code exists in the table; based on an output of the alias code search means, a part of the input address code, or All of the aliases corresponding to the address codes in the matched table Alias code replacement means for replacing with an ascode and outputting; destination barcode printing means for converting the destination code into destination barcode information based on the output of the alias code replacement means and printing it on a delivery; and the document A delivery processing apparatus, comprising: a sorting unit that sorts a delivery based on an output of one of a recognition unit and an address information input unit. 4. A destination code system having an upper limit of a code length is defined for an address code representing coded address information, and the destination code is converted into barcode information and printed on a delivery. The destination barcode or the destination code is converted into barcode information by the sender, and the sender's barcode printed on the delivery in advance is converted into digital image data for recognition, and the delivery is performed based on the recognized barcode information. A delivery processing apparatus for classifying articles, a bar code recognizing means for recognizing the destination bar code or sender bar code printed on the delivery, and outputting the recognized result as a destination code, In the code system, a destination code of a code system different from a normally used system is defined using an escape code, and a destination code of the different code system is defined. Alias code that assigns the address code to the address, defines the assigned destination code as an alias code having a meaning equivalent to the assigned address code, and holds a list in which the defined alias code and the assigned address code are associated with each other. Table and the destination code output from the destination barcode recognition means, and refer to the alias code table to determine whether an alias code matching part or all of the input destination code exists in the table. Alias code search means for searching whether or not, based on the output of the alias code search means, an alias code obtained by replacing part or all of the input destination code with an address code corresponding to the alias code in the matched table Restoration means and alias code restoration means A delivery processing apparatus, comprising: sorting means for sorting deliveries based on output. 5. A destination code system in which an upper limit of a code length is provided for an address code representing coded address information is defined, and a destination code is stored in a destination information database storing destination information of a delivery. A bar code printing device that converts code information into a bar code and prints the same on a delivery, and defines, in the destination code system, a destination code having a code system different from a normally used system using an escape code. Assigning the address code to the destination code of the different code system, defining the assigned destination code as an alias code having a meaning equivalent to the assigned address code, and associating the defined alias code with the assigned address code. An alias code table holding a list of addresses, and destination information including an address code from the destination information database. And destination information retrieval means for, enter an address code output from the destination information retrieval means,
An alias code search unit that refers to the alias code table and searches whether or not an address code that matches part or all of the input code exists in the table; based on an output of the alias code search unit An alias code replacing means for replacing a part or all of the input address code with an alias code corresponding to the address code in the matched table and outputting the same, and the destination code based on an output of the alias code replacing means. And a destination barcode printing unit that converts the destination barcode information into destination barcode information and prints the destination barcode information on a delivery. 6. An electronic medium in which a destination code system having an upper limit of a code length is defined for an address code representing coded address information, and wherein the destination code and the address code are stored. In the destination code system, a destination code of a code system different from a system normally used is defined using an escape code, the address code is assigned to the destination code of the different code system, and the assigned destination code is assigned. An electronic medium, comprising: an alias code table that defines an alias code having a meaning equivalent to an address code, and stores a list in which the defined alias code and the assigned address code are associated with each other.
