Description

  The present invention relates to a data generation apparatus for tax-exempt documents that can easily generate data for creating tax-exempt documents such as export duty-free article purchase record slips and purchase pledges using the information described in the passport, and The present invention relates to a tax exemption document creation system and a tax exemption document creation method.

  As a general rule, sales tax is levied when businesses sell products in Japan. However, the sales tax is exempted if the sale is an export transaction. For example, when non-residents such as foreign tourists who come to Japan from overseas purchase goods at an export goods store (so-called duty-free shop), no consumption tax is imposed under certain requirements. In other words, consumption tax is exempted for certain goods purchased at duty-free shops for the purpose of bringing foreign tourists, etc. out of the country as souvenirs. In addition to the above, goods carried by a resident (overseas traveler) who departs from Japan on an overseas trip or the like are also exempted (export tax exemption) if they meet certain requirements.

When a business operator in an export goods sales area sells tax-free goods to non-residents, a predetermined procedure is required. In other words, the business operator must provide information on the purchaser (landing date, passport type, passport number, nationality, purchase date, purchaser's name and year of birth) described in the passport presented by the purchaser (non-resident). Export duty-free goods that include information on the company itself (the jurisdiction tax office, tax payment area, sales location and name of the seller), and information on purchases (purchasing facts, product name, quantity, unit price, etc.) You must create a purchase record slip, paste it on your passport, etc. and press the tally.
In addition, the business operator receives the purchase pledge that the purchase pledged that the purchaser will take home abroad later, and receives the purchase pledge received from the date of sale. It must be stored for 7 years from the day after 2 months from the day after the last day.

By the way, since it takes time to manually create the above-described export duty-free article purchase record slip and purchase pledge, it has been conventionally proposed to create these mechanically. For example, Patent Document 1 describes a system that reads a two-dimensional code of a landing permit affixed to a passport and creates an export duty-free article purchase record slip and a purchase pledge. This system is equipped with a computer, a 2D code reader, and a printer. The 2D code reader reads the 2D code displayed on the passport to obtain personal data, and the local tax office, tax payment area, seller name and name are specified. Enter additional data including, and print export duty-free article purchase record and purchase pledge.
In Patent Document 2, as a means for mechanically reading passport information, passport information described in a passport machine-readable format is read by OCR (optical character recognition), and personal data is obtained from the read information. A handheld portable device is described.
Furthermore, Patent Document 3 is a technology that uses a license instead of a passport, but uses the information read by OCR for the license number and expiration date written on the license, and the license for the name and address Describes a system for creating a document using character images in the name area and address area.
Note that the export duty-free article purchase record slip and purchase pledge are described in Non-Patent Document 1, for example.

When re-reading is performed and it is determined that the country-specific reading record value is less than the reading reference value, the character image data is displayed by the display means. When character display of the character image data is available, using the processing image data to generate document data, character display character image data when it difficult to use generates document data for handwriting.

Therefore, when the text data is successfully generated from the character information described in the passport, the device of the present invention can generate the document data using the text data as in the conventional case.
If valid text data is not generated, the device of the present invention generates document data using the character image data. Prior to using the character image data, the display device displays the character image data. Check the character display status of the character image data. When it is determined that the character display can be used, the document data is generated using the processed image data that has been processed such as cutting out a required area from the character image data. When it is determined that the character display of the displayed character image data is difficult to use, the use of the character image data is stopped and handwritten document data is generated.

Therefore, according to the apparatus of the present invention, even when text data cannot be used, it is possible to easily create a tax-exempt document that accurately reflects the information of the passport. be able to.

In addition, when using the character image data, the device of the present invention uses the character image data only when the character display is usable, and uses the character image data when the character display of the character image data is not suitable for use. Since the data for handwritten documents is not created, it is possible to reliably generate proper data for tax-exempt documents, and to avoid accidentally creating tax-exempt documents that contain unclear or unreadable text display. it can.

  Furthermore, the country-specific reading result value assigned to the country information is compared with the reading reference value to determine the readability of the passport character information, and it is determined that the country has a high readability. Performs re-reading of character information to improve the availability of text data, and if it is determined that the country has low readability of character information, it will proceed with the process of using character image data, so tax-exempt documents The creation efficiency can be improved.

  That is, the present invention pays attention to the fact that there is a difference in the readability of passport information depending on the issuing country, and the use of the character image data of the passport information is used for a country that is evaluated as having a low possibility of successful text data generation. By giving priority, it is possible to improve the efficiency of document data generation.

In short, the device of the present invention relates to the display state of the passport in generating the tax exemption data.
1) When valid text data can be generated by reading character information,

3) If character image data is difficult to use,
And adopting an appropriate method according to each case, it is possible to efficiently generate data for tax-exempt documents.

  According to the second aspect of the present invention, the apparatus further comprises black background ratio measuring means for measuring the black background ratio in the character image data acquired by the reading means, and this black background ratio is compared with a predetermined reference ratio value, Determine the availability of text data. Therefore, since it is possible to avoid the use of text data having a high surplus ratio higher than the reference ratio value and a high probability of including erroneous conversion, it is possible to reduce the possibility of generating data for tax-exempt documents including erroneous entries.

  According to the third aspect of the present invention, the apparatus further comprises line width measuring means for measuring the line width of the character in the character image data acquired by the reading means, and compares the line width with a predetermined line width reference value. Then, the availability of the text data is determined. Therefore, it is possible to avoid the use of text data whose line width measurement value exceeds the allowable range of the line width reference value and is likely to contain many erroneous conversions. Can be lowered.

According to the tax exemption document creation system according to the present invention as set forth in claim 4 (hereinafter referred to as “the present invention system”), the tax exemption document is generated by the printer based on the document data generated by the above-described tax exemption document data generation device. Because it is printed, tax-exempt documents can be created easily.

  The tax exemption document creation method according to the present invention described in claim 5 (hereinafter referred to as “the present invention method”) is based on the character image data read by the reading means when preparing the tax exemption document using the character information of the passport. When valid text data can be generated, document data is generated using this text data. If valid text data is not generated, the country-specific reading actual value assigned to the country information is set. Compared with the reading reference value set based on the average reading success rate of text data, if the country reading actual value is greater than or equal to the reading reference value, the character information is read again, and the country reading actual value is the reading reference When the value is less than the value, the character image data is displayed by the display means, and when the character display of this character image data can be used, it is processed and added. It generates document data using an image data, when the character display of the character image data is difficult to use generates document data for handwriting, on the basis of these documents for data, to print the exemption documents in the printer.

Therefore, according to the method of the present invention, even when valid text data cannot be generated from the character information of the passport, it is possible to generate the data for the tax exemption document using the character image data. The ratio to be created can be reduced.

Further, the method of the present invention relates to the display state of the passport when generating the tax exemption document data. 1) When the text information can be read to generate valid text data,
2) When valid text data cannot be generated but character image data can be used,
3) Since it is classified into cases where it is difficult to use character image data, and an appropriate method is adopted according to each case, it is possible to efficiently generate data for tax-exempt documents.

Furthermore, since the method of the present invention uses the character image data only when the character display can be used when using the character image data, it is possible to reliably generate appropriate tax-exempt document data, It is possible to avoid the creation of tax-exempt documents that contain unreadable characters.

According to the method of the present invention according to claim 6, the availability of the text data is determined based on at least one of the black background ratio in the character image data or the line width constituting the character. Therefore, it is possible to avoid the use of text data that has a high probability of surplus or line width measurement and is likely to contain many erroneous conversions, thus reducing the possibility of generating data for tax-exempt documents that contain errors. be able to.

Passport information consisting of alphanumeric characters and symbols of 44 digits and two lines that are internationally standardized. The present invention device 2 reads the lower passport information description column Q by OCR, and generates text data. Regarding the description form of personal data information on the upper part of the page, the description items, layout, and characters used have some differences depending on the passport issuing country, whereas the passport information description column Q in the lower part is standardized. OCR characters (OCR-B) are used, and there are few differences in the description mode depending on the country of issue. Therefore, by making the lower passport information description column Q as a reading target, it becomes difficult for reading errors to occur, and it is possible to reliably generate document data in which the personal information described in the passport is accurately reflected.

As shown in FIG. 2B, in the passport information entry column Q of the passport P, the upper row shows the passport type / issue country code / last name / first name, and the lower row shows the passport number / nationality. / Birth date / expiration date is described in a predetermined format.

  In this example, the tax-exempt document 4 printed by the printer 3 based on the data for the tax-exempt document transmitted from the device 1 of the present invention is the export duty-free article purchase record slip 4A shown in FIG. This is the purchase pledge 4B shown in FIG. Of the items recorded on the export duty-free article purchase record slip 4A and purchase pledge 4B, passport P passport information is used for passport type, passport number, nationality, name, and date of birth. In addition, the export duty-free article purchase record sheet 4A records the jurisdiction tax office, tax payment area, merchant name, merchant location, resident status, and landing date. The merchant name, status of residence, and landing date are recorded. Items other than the date of landing are items that can be entered in advance. The landing date can be input separately when the document data is created, or can be configured to be automatically input.

  Next, the configuration of the inventive device 2 will be described in more detail with reference to FIG.

The processing of the character image data by the image data processing means 25 refers to a process for cutting out a necessary part of the character image data acquired by the reading means 21 or a process for changing the size of the cut out part to an appropriate size.
The generation of text data by the text data generation means 26 refers to a process of assigning a character code to each character included in the character image data using the OCR function, and the text data is generated by the assigned character code group. .

The document format data stored in the first storage means 30 is, for example, the document format data of the export duty-free article purchase record slip 4A and purchase pledge 4B illustrated in FIG. 3, and includes the jurisdiction tax office, tax payment place, seller Items that do not need to be changed, such as name, seller location, and resident status, can be recorded in advance.

The second storage means 31 stores information related to the text data generation process in association with the country information of the processed passport, and stores, for example, the total number of processes, the number of successful and unsuccessful text data generations, and Country information regarding the passport issuance country is stored for each processing step. These pieces of information may be made into a database. The second storage unit 31 further stores country-specific reading results, reading reference values, and processing determination reference values calculated or set based on these pieces of information.
The country-reading actual value is a numerical value obtained by compiling the success rate of the process of generating text data from character image data by passport issuing country, (country-reading actual value) = (number of successful cases in a specific country) ÷ (Total number of transactions in a specific country) x 100.
The reading reference value is a reference value set for the actual reading value by country to distinguish whether the scanned character image data is “text cannot be generated” or “text can be generated”. It is. This reference value is set based on an average reading success rate expressed as (average reading success rate) = (total number of successful cases) / (total number of processed cases) × 100, for example.
The process determination reference value is a reference value for determining whether to perform a re-reading process or to determine that text generation is not possible for those determined to be possible to generate text. It is set for the average reading unsuccessful rate expressed by: (unsuccessful reading rate) = (total number of unsuccessful cases) / (total number of processed cases) × 100

  In addition, although the 1st memory | storage means 30 and the 2nd memory | storage means 31 can be comprised so that the function of these two means may be provided in a single memory | storage device, you may comprise these with a respectively separate memory | storage device. .

It is also possible to configure such that the availability of the generated text data is determined based on the measurement value of the black background ratio or the line width. The black background ratio measuring means 28 and the line width measuring means 29 will be described later.

In general, the control means 24 is constituted by a CPU (Central Processing Unit). As shown in FIG. 4, the control unit 24 is configured to have the functions of an image data processing unit 25, a text data generation unit 26, a document data generation unit 27, a black background ratio measurement unit 28, and a line width measurement unit 29. It is also possible to do.

  The present invention device 2 configured as described above can be configured by using a portable scanner such as Handy Terminal BT-W85T manufactured by Keyence Corporation. This type of portable scanner preferably has a weight of 500 g or less. Moreover, although it does not specifically limit as the printer 3 with respect to the said product, For example, Toshiba Tec Corporation make and pocket printer B-EP2DL-GF30-R etc. can be used.

Next, the procedure for creating the tax exemption document 4 using the passport character information by the system 1 of the present invention will be described with reference to the flowchart shown in FIG. The tax exemption document creation method according to the present invention includes the following steps.

Using the reading means 21, the passport information entry column Q of the passport P is optically read to perform a scanning process for acquiring character image data (S1). The character image data is stored in the first storage unit 30. The scanning may be performed by reading two rows of passport information at the same time or one row at a time. Further, one line may be read by one scan or one line may be read by two or more scans. In the case of reading by a plurality of scans, it is desirable that the control unit 24 performs data processing so that the read data of the overlapping portion in each scan does not overlap.

The text data generation unit 26 determines whether the text data has been successfully generated from the character image data acquired by the reading unit 21 by the OCR function (S2). The text data includes personal data such as passport type, country of issue, surname, first name, passport number, nationality, date of birth, and expiration date recorded in the passport information.

When valid text data is generated by the text data generation means 26 (S3), the country information included in the text data is acquired, and the country information associated with the text data and the original character image data is updated ( At the same time, the generated text data is stored in the first storage means 30 (S5). Then, the possibility of using text data is determined (S6).

  In the process of determining the availability of text data, text image data is not used and text image data is preferentially used when it is predicted that the error conversion rate when generating text data from character image data is high. The selection is made. Methods for evaluating the possibility of erroneous conversion include a method based on the proportion of the black background in the passport passport information entry column Q, a method based on the thickness (line width) of the written character line, an evaluation based on country information, etc. Is mentioned.

<Judgment method based on the proportion of black background>
When the reading means 21 reads the passport information description column Q of the passport, the ratio of the black background portion in this description area is simultaneously measured. When the ratio of the black background portion is large, it is assumed that the description area is dirty or the printing is too thick, and it is predicted that the possibility of erroneous conversion is high. Therefore, a reference value for the ratio of the black background is determined in advance, and when the measured ratio of the black background is larger than the reference value, it is determined that the conversion error rate is high, the use of the text data is stopped, and the character image data is used. Proceed with document preparation. When the ratio of the black portion is below the reference value, the document creation using the text data is advanced. The determination based on the ratio of the black background portion may be automatically performed by the processing unit 2D.

  Alternatively, when the passport P information of the passport P is read by the reading means 21, the ratio of the black background portion in the reading area is calculated by the control means 24, and the calculation result 6a is displayed on the display means 23 as shown in FIG. It is also conceivable that the selection keys 6b and 6c for selecting whether to use text data or character image data are displayed and selected by the user. Here, when a “text” selection key 6b is selected as shown in FIG. 6B, a tax-exempt document is created using the text data. On the other hand, when the "character image" selection key 6c is selected, a tax exemption document using character image data is created.

  The selection key 6b. When displaying 6c, it may be recommended to display which of text data and character image data is suitable based on the numerical value of the ratio of the black character portion. In the example of FIG. 6B, the text data is more suitable, and “text” is surrounded and displayed by a rectangular frame. In the recommended display, for example, a reference value of the ratio of the black background portion is determined in advance, and the text data is recommended when the ratio of the black background portion of the read passport is equal to or less than the reference value. It is made to recommend data.

  In the above example, it is determined that the error conversion rate is high when the ratio of the black background portion is larger than the reference value, but it is assumed that the printing is thin even when the proportion of the black background portion is too small, Similarly, it is predicted that erroneous conversion is likely to occur. Therefore, a lower limit value of the ratio of the black background portion may be set, and even when the lower limit value is smaller than the lower limit value, the use of the text data may be stopped and the document creation using the character image data may be advanced.

<Judgment method by line width (line width)>
When reading the passport information of the passport P by the reading means 21, the thickness (width) of the lines constituting each character is measured, and the possibility of erroneous conversion is predicted based on the average value of the line widths. Is also possible. The measurement target of the line width may be all characters or arbitrarily selected characters. If the line width constituting each character is too thick, it is predicted that erroneous conversion is likely to occur. Therefore, a reference value for the line width is set, and if the average line width is less than the reference value, text data is used, and if it is thicker than the reference value, use of character image data is selected. What is necessary is just to comprise. Note that it may be determined based on the maximum value and the minimum value of the line width instead of the average value of the line width.

<Judgment method based on country information>
Depending on the error conversion rate linked to the country information, it may be configured to automatically select which character image data or text data is used. This is because even when text data is successfully generated by the text data generating means 26, it may be preferable to avoid using text data in a country where the erroneous conversion rate is very high.

  Based on the erroneous conversion rate data for each country (see FIG. 7), the user can determine whether to use the character image data acquired by the reading means 21 as it is or to use text data. You can also. For example, when the passport information of the passport P is read by the reading means 21, as shown in FIG. 8A, the error conversion rate data 8a linked to the country information of the issuing country read from the passport is displayed. And display the selection keys 8b and 8c for selecting whether to use character image data or text data. Here, when the "text" selection key 8b is selected, the passport information is saved as text data in the first storage means 30, and the tax exemption document is generated by the printer 3 using the document data generated using the passport information. Is printed. On the other hand, when the “character image” selection key 8 c is selected, document data is generated using the character image data, and a tax-exempt document is printed by the printer 3 using the document data.

When the selection keys 8b and 8c are displayed, it may be recommended to display which of text data and character image data is suitable. In FIG. 8B, “character image” is recommended and surrounded by a rectangular frame, with character image data being suitable.
In the recommended display, for example, a reference value for the erroneous conversion rate is determined in advance, and text data is recommended if the erroneous conversion rate in the country of the read passport is less than or equal to this reference value. It is possible to recommend image data.

  The valid text data determined to be usable as a result of the determination process described above is output to the document data generation means 27 (S7), and is converted into the text data in the document format data stored in the first storage means 30. Add passport type, first name, last name, passport number, nationality, date of birth personal data included. In the document form data, known items such as the tax office, tax payment area, seller name, seller location, resident status, etc. are recorded in advance. Further, necessary information such as the date of landing is additionally input from the input means 22 to complete the target tax exemption document data (S8).

The document data thus completed is transmitted to the printer by the communication means 32. The printer 3 performs a printing process based on the received document data, and creates the tax-exempt documents 4 such as the export duty-free article purchase record slip 4A and the purchase pledge 4B illustrated in FIGS. S9).

D) In step S2, if the text data generation unit 26 cannot generate valid text data from the character image data, the character image data acquired by the reading unit 21 is output for creating document data. (S10). At this time, it is determined whether or not the country information is read as text data from the character image data (S11). If the country information can be read as text data, the country information linked to the text data is updated based on this data (S12). If the country information cannot be read as text data, the country information is separately input through the input means 22 and the country information linked to the character image data is updated (S13).

  Next, the country-specific reading results and reading reference values stored in the second storage unit 31 are referred to (S14), and the country information linked to the character image data is determined based on the reading success rate of the text data. The allocated country-specific reading result value is compared with a reading reference value set based on the average reading success rate of the text data (S15). This comparison process is a process for confirming whether there is a possibility of generating text data for character image data. The country-specific reading performance value is a total of the text data generation success rates for each issuing country. Depending on the passport production situation of the issuing country, there are variations in print quality and paper quality, which will affect the success rate of text data generation, so there is a certain correlation between the issuing country and the success rate. It is done. Therefore, by comparing the reading reference value set based on the average reading success rate and the reading result value for each country, it is possible to evaluate the possibility of generating text data based on the issuing country.

When it is determined that the country-specific reading result value is less than the reading reference value, that is, when the text data is not available, the character image data is stored in the second storage means 31 (S16), and then the character image data is stored. The data is output to the display means 23 (S17) and displayed on the screen (S18).

Next, the character display of the character image data displayed on the screen is confirmed (S19). When the character display is usable, that is, when the contents of the description can be read clearly, the character image data is temporarily stored (S20). The image data processing means 25 performs a process of cutting out only a portion necessary for creating document data. That is, the portion corresponding to the passport type, surname, first name, passport number, nationality, date of birth in the passport information description column Q shown in FIG. Subsequently, the document data generation unit 27 pastes each part of the character image data to predetermined portions of the document format data stored in the first storage unit 30. Further, necessary information such as the date of landing can be additionally input through the input means 22 and the like, and the document data in which the required items are recorded can be generated (S22).

The generated document data is transmitted to the printer 3 by the communication means 32, and the printer 3 prints the tax exemption document 4 based on the received document data (S23).

When the character display of the character image data displayed on the display means 23 is difficult to use, that is, when the description of the characters is not clear, the character image data is temporarily stored (S24), and then the document data generating means 27 Using the document format data stored in the first storage means 30, the tax exemption documents for handwritten entry with the passport type, surname, first name, passport number, nationality, date of birth, etc. left blank Document data is generated (S25).

The generated document data is transmitted to the printer 3 by the communication means 32, and the printer 3 prints the tax exemption document 4 based on the received document data (S26).

If it is determined in the determination process in step S15 that the country-specific reading result value for the country information linked to the character image data is equal to or greater than the reading reference value, the character image data is temporarily saved (S30) and stored in the second memory. The processing judgment reference value stored in the means 31 is referred to (S31). The character image data for which the country-specific reading result value is determined to be greater than or equal to the reading reference value is determined to have the possibility of text generation, but the possibility of text generation is further confirmed based on the processing determination reference value. Specifically, the unsuccessful rate of text data generation compiled for each country is compared with the processing determination reference value. If the unsuccessful rate has not reached the processing determination reference value, the reading means 21 re-reads the character information of the passport P. Read. If the unsuccessful rate is equal to or greater than the process determination reference value, it is determined that the generation of text data is impossible, and the process proceeds to the character image data output step of S17 in order to proceed with the generation of document data based on the character image data.

(Other embodiments)
When the country name corresponding to the second storage unit 31 is not stored for the country information read from the passport, the display unit 23 displays that fact. The user who sees this display determines the country of issue from the description of the passport P and inputs it through the input means 22.

  For information required for creating tax-exempt documents other than personal data included in passport passport information, in addition to input from the input means 22, it is also possible to perform input operations from a device such as an external personal computer connected to the connection section .

  When the document data is generated using the text data, the text data to be printed may be displayed on the display unit 27 before printing to check whether there is any erroneous conversion. In this case, the characters that are likely to be erroneously converted may be alerted by displaying such characters as underlined.

  As described above, according to the system 1 of the present invention, when valid text data is generated from the character image data acquired by the reading unit 21, a tax exemption document is created using the text data, and the character image is generated. When valid text data cannot be generated from the data, if character display of the character image data is available, a tax exemption document is created using this, and if character display of the character image data is difficult to use, Create tax-exempt documents. Therefore, the system 1 of the present invention generates document data by an appropriate method according to the situation even when the text data cannot be generated as well as when the text data can be generated, so that the passport information is accurately reflected. It is possible to efficiently create tax-exempt documents that are correct in matters.

In addition, since the information that evaluates the success rate of text data generation by country is used, it is possible to efficiently select the most suitable method for creating tax-exempt documents based on the country information, and to improve the efficiency of creating tax-exempt documents. .

  If the device 2 of the present invention is composed of a portable scanner, only the printer 3 needs to be installed in a store that sells duty-free products, and the required occupation area is small. Therefore, since a personal computer or the like for creating tax-exempt documents can be dispensed with, there is an advantage that the atmosphere of the store interior is less likely to be impaired.

  The present invention is suitably used, for example, in a store that sells tax-exempt products. The present invention can also be applied to the creation of tax-exempt documents that use passport information other than export duty-free article purchase record slips and purchase pledges. Furthermore, it is possible to read and use not only the passport information at the bottom of the passport but also the personal data at the top.
