The specific design features of the present invention as disclosed herein, including, for example, specific dimensions, orientations, locations, and shapes will be determined in part by the particular intended application and use environment. 
         [0031]    In the figures, reference numbers refer to the same or equivalent parts of the present invention throughout the several figures of the drawing. 
       DETAILED DESCRIPTION 
       [0032]    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. 
         [0033]    In the following description and the accompanying drawings, like reference numerals designate substantially like elements, and the duplicated description will be omitted. In describing the present invention, well-known related functions or configurations will not be described in detail since the detailed description for the well-known related functions or configurations may unnecessarily obscure the understanding of the present invention. 
         [0034]    The present invention relates to a system and a method of automatically setting sorting boxes for automatic mail sorting and will be described below with reference to  FIGS. 1 to 5 . However, those skilled in the art will easily understand that the detailed description of this specification with reference to the drawings is just exemplified because the present invention is expanded beyond the limited exemplary embodiments. 
         [0035]      FIG. 1  is a block diagram of a system of automatically setting sorting boxes for automatic mail sorting according to an exemplary embodiment of the present invention. 
         [0036]    A system  1  of automatically setting sorting boxes of  FIG. 1  includes an information acquiring unit  10 , a sorting unit  20 , and a display unit  30 . 
         [0037]    The information acquiring unit  10  scans mail to acquire information of the mail. The information of the mail of the information acquiring unit  10  may be character recognition information of the mail or barcode information of registered mail. A scanning method of the information acquiring unit  10  may be character recognition through image photographing, information recognition using an RFID tag, barcode recognition through a barcode scanner, or the like, and is not limited to the listed methods. 
         [0038]    The information acquiring unit  10  finally acquires address information from the character recognition information of the mail or finally acquires address information from the barcode information based on a registered mail DB (not illustrated). 
         [0039]    Particularly, in the case of the character recognition, an apparatus capable of recognizing a character may include an optical character reader (OCR) capable of recognize both printed characters and handwritten characters, an optical mark reader (OMR) capable of recognize specific characters, and a magnetic ink character reader (MICR) and an image recognition apparatus as a next-generation recognition apparatus may become an exemplary embodiment of the present invention. 
         [0040]    Since reliability of a reading result is important in the recognition by the OCR, a predetermined degree of limit is set on an input character in order to secure recognition information. A standard character type of an OCR printed character includes OCR-A and OCR-B, and initially, the OCR-A type is used, but presently, the OCR-B type is used because it is not easy for a person to read the OCR-A type. Since it is difficult to strictly define the shape of a handwritten character by using a mechanical size unlike the printed character, there are several problems in recognizing the handwritten character. As a general index, whether to clearly distinguish a characteristic line configuring the character, easiness to write, whether to have a natural character shape, and the like are primarily examined. The size and the shape of a character writing column are simultaneously limited in order to stabilize the size and the shape of the handwritten character. A character recognition method in the related art may be generally classified into pattern matching and structure analysis. The former is primarily used to recognize the printed character and the latter is primarily used to recognize the handwritten character. An intermediate character recognition method of both methods includes feature matching and stroke analysis which are used dividually in accordance with respective uses or purposes. 
         [0041]    The sorting unit  20  determines information to be displayed in each sorting box into which the mail is input based on a predetermined stored mail information DB and transmits the information to be displayed in each sorting box to the display unit  30 . The information to be displayed in each sorting box includes address information of the sorting box and mail input display. 
         [0042]    The mail information DB as a DB storing information for processing the mail or verifying address information of the mail includes a registered mail statistics DB, a census statistics DB, a postal area DB, and a sorting box DB. The DB will be described below. 
         [0043]    The display unit  30  receives the information to be displayed in each sorting box from the sorting unit  20  and displays the received information in each sorting box. 
         [0044]    The display unit  30  allows the address information and the mail input display to be displayed in each sorting box. The mail input display means displaying the mail so as to be input into a corresponding sorting box. In a character display method of the display unit  30 , a character having a simple character shape such as English, numerals, or Korean is a little different from a character having a complicated character shape such as Chinese characters in terms of generation method, but the character display method is basically divided into a dot method, a stroke method, and a monoscope method. 
         [0045]    A device type of the display unit  30  may include one of a CRT display device, a storage type display device, electroluminescence (EL), a liquid crystal display (LCD), a light emitting diode (LED), an organic light emitting diode (OLED), and a plasma display panel (PDP). 
         [0046]      FIG. 2  is a structural diagram of the information acquiring unit  10  according to the exemplary embodiment of the present invention. 
         [0047]    The information acquiring unit  10  illustrated in  FIG. 2  includes a scanner  110 , a mail supplying device  100 , and a mail conveying device  120 . The mail supplying device  110  automatically supplies a large amount of mail to the scanner. The present invention is not limited to the mail supplying device and the mail may be allowed to individually pass through the scanner. The scanner  110  scans the mail supplied from the mail supplying device to acquire mail information. As described above, the mail information may be address information of the mail or barcode information of the registered mail. The mail that passes through the scanner  110  is conveyed to the sorting box through the mail conveying device  120 . 
         [0048]      FIG. 3  is a block diagram of the sorting unit  20  according to the exemplary embodiment of the present invention. 
         [0049]    The sorting unit  20  of  FIG. 3  includes a mail information DB and a processing server  220 . 
         [0050]    The mail information DB may include a census statistics DB  210 , a postal area DB  220 , a registered mail statistics DB  240 , and a sorting box DB  250 . 
         [0051]    Address information of a building, an administrative district, or a road in the postal area for each mailman is stored in the postal area DB  220  in advance and the processing server  220  of the sorting unit  20  determines information to be displayed in each sorting box in accordance with the postal area information. In the determination method, the information to be displayed in each sorting box may be determined by one sorting box per one town and the information to be displayed in each sorting box may be determined by one sorting box per two towns. Alternatively, the information to be displayed in each sorting box may be determined by one sorting box per one building. The present invention is not limited to the aforementioned determination method. When the postal area information is updated, the information to be displayed in each sorting box is also updated. 
         [0052]    The registered mail statistics DB  240  stores mail amount statistics of the registered mail in advance, and the processing server  220  of the sorting unit  20  determines the information to be displayed in each sorting box in accordance with the mail amount statistics. In this case, the processing server  220  may determine the information to be displayed in each sorting box so that a sorting box corresponding to an area having more mail amount is assigned to a position closer to a mail sorting operator. A method of determining the information to be displayed in each sorting box so as to evenly input the mail in each sorting box in accordance with the mail amount may be used. The present invention is not limited to the aforementioned methods. 
         [0053]    When the registered mail statistics DB is updated, the information to be displayed in each sorting box is determined based on the updated registered mail statistics DB. 
         [0054]    The census statistics DB  210  stores population density in advance, and the processing server  220  of the sorting unit  20  determines the information to be displayed in each sorting box in accordance with the population density. In this case, the processing server  220  may determine the information to be displayed in each sorting box so that a sorting box corresponding to an area having higher population density is assigned to a position closer to the mail sorting operator. A method of determining the information to be displayed in each sorting box so as to evenly distribute population density may be used. The present invention is not limited to the aforementioned methods. 
         [0055]    The information displayed in each sorting box based on the mail information DB is address information of each sorting box. The processing server  220  of the sorting unit  20  updates the sorting box DB  250  storing, in advance, address information the existing sorting box by using the address information of each sorting box. 
         [0056]    The processing server  220  of the sorting unit  20  determines the information to be displayed in each sorting box by matching the determined address information of each sorting box and the address information acquired by the information acquiring unit, and the information is an input display indicating a sorting box into which the mail is input. 
         [0057]      FIG. 4  is a schematic diagram of the display unit  30  according to the exemplary embodiment of the present invention. 
         [0058]    The display unit  30  of  FIG. 4  includes a mail input display  300  and a sorting box address display  310 . 
         [0059]    The display unit  30  receives the information to be displayed in each sorting box and displays the received information. The information to be displayed in each sorting box is address information of each sorting box and a mail input display. The address information of each sorting box is displayed in the sorting box address display  310  and the sorting box to be input with the corresponding mail is displayed or lighted in the mail input display  300 . 
         [0060]    The exemplary embodiment of the present invention is described below. If the sorting box address display  310  needs to be differentiated due to a change of the postal area of the mailman, an increase/decrease of the population density, changes of the building, the administrative district, the road, the address, or the like, in the existing case, inconvenience in which the mailman needs to manually display the changes may be caused and differentiating the sorting box address display  310  may be an additional business element. However, according to the exemplary embodiment of the present invention, the change of the postal area or the changes of the building, the administrative district, or the like is performed through updating the postal area DB, the change by the increase/decrease of the population density is performed through updating the census DB, and when updating the registered mail statistics DB, the information to be displayed in each sorting box in the processing server  200  is automatically updated, thereby attempting the efficiency of the business. 
         [0061]    Another exemplary embodiment of the present invention is described below. When the position and address information of the sorting box are changed due to the situation, the mailman needs to adapt to changed sorting box and sorting box information in the existing case. In the registered mail, the mailman has inconvenience to scan barcode information with a PDA one by one. According to the exemplary embodiment of the present invention, since information on the large amount of mail is scanned in the information acquiring unit  10 , the trouble may be saved and since the corresponding mail is input into the sorting box which is lighted depending on the lighting of the mail input display  300  of the sorting box, the problem may be solved. 
         [0062]      FIG. 5  is a flowchart of a method of automatically setting sorting boxes for automatic mail sorting according to an exemplary embodiment of the present invention. 
         [0063]    An information acquiring unit  30  of a system of automatically setting sorting boxes for automatic mail sorting acquires information of mail by scanning the mail (S 400 ). 
         [0064]    The information of the mail may be character recognition information of the mail or barcode information of registered mail. The character recognition information is finally acquired as address information, and the barcode information is finally acquired based on a registered mail DB as the barcode information. As a scanning method, barcode recognition using a barcode sensor, character recognition through image photographing and reading, or information recognition using an RFID tag may be used. However, the present invention is not limited to the aforementioned methods. The acquired mail information is transmitted to a sorting unit  20 . 
         [0065]    The information acquiring unit  10  may include a scanner acquiring information of the mail, a mail supplying device automatically supplying a large amount of mail to the scanner, and a mail conveying device automatically conveying the scanned mail.
