Can be.

The barcode reader 105 identifies the barcode region from the image information acquired through the image information acquirer 105 to obtain sender information and recipient information.

In general, when sending a mail, sender and recipient information is printed on the mail in the form of a barcode through a barcode printer, and then sent to each recipient. Accordingly, the bar code reading unit 105 reads the printed bar code at the time of returning the mail and acquires the sender information and the recipient information.

On the other hand, the sent mail may be returned due to the recipient's moving or unknown address.In the past, the courier in charge collects the returned mail after collecting the returned mail at the time of return. The reason for checking the reason was used.

However, since the method checks at the post office collectively, not only the accuracy of the reason for the return is lacking, but also there is a problem that it is impossible to automatically recognize the reason for the return by using a circular aliquot (see FIG. 4).

In order to solve such a problem, an embodiment according to the present invention prints a standardized return information column on the outside of the mail in advance to check the reason for return of the returned mail and the information about the delivery officer in charge, or the attendant in charge paints on the spot. After stamping the return information field by using, the deliveryman in charge of the mail delivery is not completed in the field will display the reason in the return information field, so the reason for the return can be secured accurately.

The area extracting unit 115 extracts a conveying information field from the image information acquired through the image information obtaining unit 105, and the conveying reason information obtaining unit 120 displays the conveying reason in which the conveying reason is displayed in the extracted conveying information field. Transfer reason information is acquired based on location information of the region. The process of obtaining the conveyance reason information by the conveyance reason information acquisition unit 120 will be described later with reference to FIGS. 5 and 6.

The courier information acquisition unit 125 may acquire contents of the courier including a return date, a courier name, and a contact information (for example, information consisting of a text file) by recognizing contents described in the courier information area illustrated in FIG. 5A. The information acquisition unit 125 may represent an OCR reader, but the present invention is not limited thereto.

Error information acquisition unit 130 is a bar code reader 110, area extraction unit 115, carrier reason information acquisition unit 120 and the delivery agent information acquisition unit 125, the sender information, recipient information or return of the mail Error information indicating whether an error has occurred in the process of obtaining the information (including the reason for return information or the deliveryman information) is obtained. That is, when the error information acquisition unit 130 fails to obtain the sender information and the recipient information of the mail because an error occurs when reading the barcode, the return information field according to the present invention may be In the case of failure to recognize the return information field due to the display of a conventional aliquot or the like, or when the return information is not correctly obtained, information that can be confirmed is obtained, and the output unit 135 and the data processing unit ( 140).

The output unit 135 includes an image information obtaining unit 105, a barcode reading unit 110, an area extracting unit 115, a transfer reason information obtaining unit 120, a delivery source information obtaining unit 125, and an error information obtaining unit ( Outputs the image information, the sender information, the recipient information, the return information, and the error information obtained through the operation 130, and the data processing unit 140 uses the input unit 145 when the error information indicates that an error has occurred. Based on the image information output through the output unit 135, the sender information, the recipient information, or the return information is reacquired and stored in the information storage unit 150. Specifically, when acquisition reason information or delivery service provider information fails, the transfer reason information or delivery service information is reacquired using the output image information.

That is, when an error occurs in the process of obtaining sender information, recipient information, or return information, the worker may manually input the corresponding information using the image information output through the output unit 135. Detailed description thereof will be described later with reference to FIG. 6.

The transmitter 155 transmits the payee information and the return information to the sender through an e-mail or a web hard drive based on the sender information.

The carrier reason information is acquired based on the positional information of the reason area, and the operator information acquisition unit 125 acquires the operator information by recognizing a character described in the operator information area of the carrier information column through OCR reading (S230).

When the mail is returned, the courier in charge may display the reason for return in the form of “O” or “√” in the return reason field of the return information field, and the return reason information acquisition unit 120 may use a pattern recognition technology. The carrier reason indication may be recognized, and the reason for the carrier may be confirmed based on the position information of the carrier reason area in which the carrier reason is displayed. That is, since the responsible person can display the reason for the conveyance in various forms, the conveyance reason information acquisition unit 120 uses the algorithm capable of recognizing the pattern of the reason for the conveyance reason so that the conveyance reason information acquisition unit 120 displays the positional information of the reason for the conveyance reason. You can check.

Subsequently, the obtained sender information, the recipient information, and the return information are stored together with the corresponding image information in the information storage unit (S240), and later, the image information is stored by giving an index number to confirm the fact that the mail is returned. do. The sender can reconfirm the fact of return of the mail by acquiring the return date and the conveying agent information through the image information.

If the acquisition of the information fails (S250), by using the image information, sender information, recipient information, return information and error information output through the output unit 130, sender information, recipient information, return information Reacquire (S260). That is, as shown in FIG. 8 to be described later, the user directly inputs information that fails to acquire while viewing the image of the returned mail output through the output unit 135 through the input unit 145.

The input unit 145 may be a keyboard, a mouse, or a microphone. In particular, when the input unit 145 is a microphone, the input unit 145 may further include a data converter (not shown) for recognizing and converting a voice signal into data. The reacquired sender information, recipient information, and return information are stored in the information storage unit 150 together with the corresponding image information (S270).

Meanwhile, in the returned mail processing system according to the present invention, the information storage unit 150 may be an external storage medium (eg, an external hard disk, USB). That is, if the image information of the returned mail, the sender information, the recipient information, and the return information are stored in an on-line server and the like is provided to the sender, the information may be leaked due to hacking. Therefore, in order to prevent this, the returned mail processing system according to the present invention may store the information in an external storage medium and then transmit the information to the sender via the Internet or directly transmit the external storage medium to the sender. Furthermore, the external storage medium may be set to update the stored information automatically at predetermined time intervals.

In addition, when the information is sent to the sender via the Internet, the sender accesses the website and transmits the information only when the personal ID and password entered match the pre-stored login information. Can be. In addition, the information may be automatically deleted after a certain period of time (eg, 15 days), thereby preventing information leakage.

Referring to FIG. 3, the sender information, the recipient information, and the return reason information obtained through the return reason information acquisition unit 120 and stored in the information storage unit 150 are sent to the sender in an encrypted form through the transmission unit 155. Since the information is transmitted to a third party other than the sender, the information cannot be interpreted, and as a result, an effect of preventing or blocking the leakage of the information can be obtained.

As shown in Fig. 3, the data file including the sender information and the like includes a system serial number including a work serial number, a work date, a system number, a mail type, an image file number, a delimiter, a payee management number, and a sender identification number. And a database read portion containing the reason for return.

In particular, the sender can check the image of the returned mail through the image file number, through which it is possible to reconfirm the fact that the mail was returned by acquiring the return date, the information of the responsible forwarding agent.

Fig. 4 shows a postal item in which a circular return information column used in a conventional return mail is indicated.

As shown in FIG. 4, when the return of the postal mail occurs in the related art, the courier in charge collects the returned postal mail in a batch and displays the reason in the return information column after the circular postmarker is sealed at the post office. However, this method not only lacks the accuracy of acquiring the return information because the post office displays the reason for return collectively, but also it is impossible to recognize the return information automatically. It took a lot of time and effort to process the mail.

FIG. 5 illustrates a mail item in which (a) return information column and (b) return information column are used in the return mail processing system according to an embodiment of the present invention.

Referring to FIG. 5A, the returned mail processing system according to the present invention extracts the returned information field from the image information and obtains the returned reason information based on the positional information of the returned reason area in which the returned reason is indicated.
