A transmission unit that transmits a text character string to the information processing apparatus, and the information processing apparatus includes the document identification information. A storage unit that stores format data of a document format corresponding to the format data reading unit that reads out the format data corresponding to the document identification information transmitted from the transmission unit, and the format data reading unit. A data writing unit for writing the text character string transmitted from the transmission unit in the read format data, and the format data in which the text character string is written by the data writing unit A code conversion unit for converting to a readable code, the format data in which the text character string is written by the data writing unit, and a composite image based on the second machine-readable code converted by the code conversion unit are generated And an image generator generated by the image generator. It is characterized in that it comprises a printing unit for printing an image.

  According to this configuration, the mobile terminal transmits the text character string and the document identification information rewritten by the text rewriting unit to the information processing apparatus. Then, the information processing apparatus generates format data based on the rewritten content based on the transmitted text character string and document identification information. In this way, in the information processing system, the data handled in the portable terminal can be only the text character string and the document identification information.

  As described above, according to the present invention, document data of various sizes can be handled using a portable terminal regardless of the data size of the format data.

  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

  As shown in FIG. 1, the information processing system according to the first embodiment is configured by connecting a mobile terminal 1, an information processing device 3, and a printer 5 via a network 7. The information processing system described in the first embodiment is a system for rewriting and printing a price tag table price used in a retail store or the like.

  The mobile terminal 1 is connected to the network 7 via a wireless LAN access point 9 connected to the network 7. The mobile terminal 1 is connected to the network 7 via the wireless LAN access point 9 and transmits / receives information to / from the information processing apparatus 3 via the network 7. Such a portable terminal 1 is used when the user tries to change the price described in the price tag table PT as shown in FIG. Specifically, the mobile terminal 1 includes a code reading unit 11 that reads a QR code printed on the price tag table PT, a code analysis unit 13 that analyzes a QR code read by the code reading unit 11, and a user performs various operations. An operation unit 15, a request creation unit 17 that creates request information to be transmitted to the information processing device 3 based on the rewrite information input to the operation unit 15, and a wireless communication unit 19 that performs wireless communication are provided.

  The code reading unit 11 reads the QR code printed on the price tag table PT based on a user instruction. The code analysis unit 13 analyzes the content of the QR code read by the code reading unit 11. Specifically, the QR code printed on the price tag table PT is assigned to the document ID as document identification information set for each predetermined document format and for each product displayed on the price tag table PT in advance. Product ID and in-form character string information indicating a character string arranged in each item in the document format. Then, the code analysis unit 13 analyzes the QR code, and extracts the document ID and the product ID included in the QR code, and the character string information in the form. Referring to the example shown in FIG. 2, the QR code printed on the price tag table PT includes a document ID corresponding to the document format of the price tag table PT, a product ID corresponding to “Chinese Banana”, and a form as a document ID. The internal character string information includes a text character string “15” indicating the quantity, a text character string “450” indicating the price, and a text character string “yen” indicating the currency unit. Then, the code analyzing unit 13 extracts the document ID, the product ID, and the character string information in the form from the QR code read result by the code reading unit 11. The code analysis unit 13 supplies the extracted in-form character string information to the operation unit 15 and supplies the extracted document ID and product ID to the request creation unit 17.

  The operation unit 15 includes an operation panel for the user to input various information to the mobile terminal, and a display panel for displaying various information to the user. And such an operation part 15 displays the text character string contained in the character string information in a form with respect to a user. Then, the user rewrites the text character string via the operation panel while referring to the displayed text character string. Specifically, as shown in FIG. 3, the display panel 21 includes a text display area 23 in which each text string is displayed, a text area 25 in which the value of the text string selected by the user is displayed, And a text area 27 for inputting a new value. Then, the operation unit 15 displays each text character string supplied from the code analysis unit 13 in the text display area 23. When the user selects a specific text string using the operation panel, the operation unit 15 displays the selected text string in the text area 25. Then, the user inputs the text desired to be changed into the text area 27 using the operation panel, and selects the OK button. For example, when the user desires to change the price of “Chinese banana”, the text character string “450” indicating the current price is selected. As a result, “450” is displayed in the text area 25. Then, the user inputs the changed price in the text area 27 and presses the OK button. As a result, change information for changing the text character string is input to the portable terminal 1. Then, the operation unit 15 supplies the changed text character string to the request creation unit 17.

  The request creation unit 17 creates request information to be transmitted to the information processing device 3 based on the text character string input to the operation unit 15 and the document ID and product ID supplied from the code analysis unit 13. The request information is information including the document ID, the product ID, and the changed text character string supplied from the operation unit 15. Further, when a text character string is not supplied from the operation unit 15, the request creation unit 17 does not include a text character string in the request information. The information processing apparatus 3 that has received such request information prints the price tag table PT that has not been converted from the text character string, assuming that the price tag table PT is reprinted. The request information created by such a request creation unit 17 is transmitted to the information processing device 3 by the wireless communication unit 19.

  The information processing apparatus 3 includes a format data storage unit 29 that stores the format data of the document format in association with the document ID, and a format that reads out the document format corresponding to the document ID transmitted from the mobile terminal 1 from the format data storage unit 29.

Then, after the declaration statement, specific data contents are described between the last stages. Between the information, information on the size of the paper, information on the orientation of the paper, and the like are described.

  In the block between and, parameters relating to the arrangement position, size, and color of the square object located in the background of the character string “Chinese banana” are described. Specifically, a parameter related to the arrangement position of the rectangular object is described in a block between and, a parameter related to the size is described in a block between and, and a parameter related to the color is a block between and It is described in. Further, the text string of the text object “Chinese banana” related to the product name, the arrangement position, and the parameters related to the color are described after the block relating to the rectangular object. And the block concerning quantity, price, and currency is described in the latter part of the product name.

  Then, the format data reading unit 31 reads the format data corresponding to the document ID designated by the user via the document selection unit 47 from the format data storage unit 29. Then, the format data reading unit 31 stores the read format data in the buffer 49.

  The product DB update unit 43 updates the product database stored in the product DB storage unit 51 based on the product ID and the text character string supplied from the request analysis unit 39. Specifically, as shown in FIG. 6, the product database is a database that stores product IDs, product names, quantities, and prices in association with each other. The information processing device 3 updates the product database each time request information is transmitted from the mobile terminal 1, and the updated product when the user tries to print the price list PT via the product selection unit 53. Reads the character string corresponding to the product name, quantity, and price from the database. Specifically, the product name, quantity, and price corresponding to the product ID selected by the user via the product selection unit 53 are read from the product database by the product data reading unit 45. The product name, quantity, and price read by the product data reading unit 45 are written in the format data stored in the buffer 49 by the form writing unit 55.

  Then, the code conversion unit 35 uses the format data stored in the buffer 49 based on the request information transmitted from the mobile terminal 1, or the document ID and the product specified by the user via the document selection unit 47 and the product selection unit 53. Based on the ID, the format data stored in the buffer 49 is converted into a QR code. The QR code generated by the code conversion unit 35 is supplied to the image generation unit 37.

  The image generation unit 37 generates a combined image of the format data stored in the buffer 49 and the QR code supplied from the code conversion unit 35. The generated composite image is transmitted as print data to the printer 5 via the form writing unit 55 and the network 7. The printer 5 prints an image based on the received print data.

  Hereinafter, the operation of the information processing system will be described in detail.

  First, the operation of the information processing system when reprinting the price tag table PT without rewriting the information on the price tag table PT will be described in detail with reference to FIG. There are two methods for reprinting the price tag table PT: a method that uses only the information processing device 3 and a method that uses the information processing device 3 and the portable terminal 1. However, both processes include the same processing. Detailed description will be given with reference to the same drawings. For example, when the price tag table PT having the QR code does not exist when the commodity is received, the user prints the price tag table PT using only the information processing device 3.

  First, when reprinting the price tag table PT using only the information processing device 3, the document ID and the product ID of the price tag table PT that the user desires to reprint using the input device 127 and the display device 129 are processed. A series of processing is started upon input to the apparatus 3. When a series of processing starts, the information processing apparatus 3 reads out format data corresponding to the input document ID in step S1. Thereafter, in step S2, the information processing device 3 reads the product name, quantity, and price corresponding to the input product ID from the product database. In step S3, the information processing apparatus 3 writes the read product name, quantity, and price in the read format data. Next, the information processing apparatus 3 generates a QR code of the format data in which each information is written in step S4, and generates print data in step S5. Thereafter, in step S6, the information processing apparatus 3 transmits the print data to the printer 5 and ends the series of processes.

  Next, when reprinting the price tag table PT using the mobile terminal 1 and the information processing device 3, the user scans the QR code of the price tag table PT to be reprinted using the barcode scanner 107 of the mobile terminal 1. A series of processing starts. When a series of processing starts, in step S7, the mobile terminal 1 analyzes the QR code and extracts the document ID and the product ID. Then, the portable terminal 1 creates request information in step S8, and transmits the request information to the information processing apparatus 3 in step S9. And the information processing apparatus 3 performs the process after step S3 based on the received request information.

  Next, a series of operations of the mobile terminal 1 when changing the price printed on the price tag table PT will be described in detail with reference to FIG.

When the user scans the QR code on the price tag table PT using the barcode scanner 107 and starts a series of operations, the mobile terminal 1 analyzes the QR code in step S11. Specifically, the character string data added to the QR code is reproduced by the mobile terminal 1 analyzing the QR code. Then, the code analysis unit 13 acquires the document ID, the product ID, and the in-form character string. Specifically, the code analyzing unit 13 is based on the QR code reading result.


Chinese banana

450
Get a circle. Then, the code analysis unit 13 uses the acquired information as the document ID “294785”, the product ID “49001”, and the character string in the form.
Chinese banana
15
450
Get a circle. These pieces of information are displayed on the operation unit 15 as text character strings.

Next, in step S <b> 12, the mobile terminal 1 determines whether change information has been input by the user. And the portable terminal 1 repeatedly performs this process until it judges that the change information was input by the user, or until a cancellation instruction | indication is input. And when the portable terminal 1 judges that the change information was input by the user, the process after step S13 is performed. For example, when the price of Chinese bananas is changed from 450 yen to 390 yen and change information indicating that the number is changed from 15 to 8 is input, the mobile terminal 1 is included in the second object. The value of “15” is rewritten to “8”, and the value of “450” included in the third object is rewritten to “390”. And as a new in-form string,
Chinese banana
8
390
A circle is generated.

  Next, in step S13, the mobile terminal 1 creates request information based on the input change information. In step S <b> 14, the mobile terminal 1 transmits the created request information to the information processing apparatus 3 and ends the series of processes. Accordingly, request information indicating that the price of the Chinese banana should be changed to 390 yen and the quantity should be changed from 15 to 8 is transmitted to the information processing apparatus 3.

  Next, the operation of the information processing apparatus 3 that has received the request information will be described in detail with reference to FIG.

  When the request information is received and a series of processing starts, the information processing apparatus 3 analyzes the request information in step S21. In step S22, the information processing apparatus 3 updates the product database based on the request information. This updates the price and quantity of Chinese bananas in the product database. In step S <b> 23, the information processing apparatus 3 reads the format data corresponding to the document ID included in the request information from the format data storage unit 29 and stores it in the buffer 49. Thereafter, in step S <b> 24, the information processing device 3 writes the contents of the text character string included in the request information in the format data stored in the buffer 49. Next, in step S <b> 25, the information processing apparatus 3 generates a QR code based on the format data stored in the buffer 49. Thereafter, the information processing apparatus 3 generates print data in step S26, transmits the print data to the printer 5 in step S27, and ends the series of processes.

  Next, the QR code generation process described above will be described in detail with reference to FIG.

  When a series of processes starts, in step S31, the code conversion unit 35 generates text character string information. Specifically, such processing is executed by the code converter 35 scanning the format data stored in the buffer 49. Next, in step S32, the code conversion unit 35 generates an additional information character string. Specifically, the processing is executed by the code conversion unit 35 combining the document ID and product ID included in the request information with the text character string information. In step S33, the code conversion unit 35 encodes the additional information character string into a QR code, and ends the series of processes.

  Next, the process in step S31 described above will be described in detail with reference to FIG.

  When a series of processing starts, in step S41, the code conversion unit 35 initializes a variable i for block search and a variable str for storing a string. Specifically, the code conversion unit 35 performs initialization by substituting the value 0 for the variable i and rewriting the variable str to an empty character string.

  Next, in step S42, the code conversion unit 35 proceeds to read to the next stage of the tag. Then, the code conversion unit 35 determines whether the next tag is a tag indicating the end of data. If the next stage tag is not present, the code conversion unit 35 executes the process of step S44.

  In step S44, the code conversion unit 35 determines whether or not the next tag is a tag indicating the start of the object. If it is determined that the subsequent stage is an object block, in step S45, the code conversion unit 35 determines whether the object is a text character string. Such processing is executed by the code conversion unit 35 determining whether or not the tag described after the tag is a tag indicating the type of object.

  If the object is a text string, the code conversion unit 35 increments the variable i in step S46. In step S47, the code conversion unit 35 reads the character string between the tags.

  In step S48, the code conversion unit 35 adds character string information to the variable str. At this time, for example, if the variable i is value 3 and the character string written between the tags is “big sale”, the code conversion unit 35 performs the following processing. First, when form = “XXXX” is specified in the tag, the code conversion unit 35 adds the character string “Great sale” to the variable str. On the other hand, when form = “XXXX” is not specified in the tag, the code conversion unit 35 adds the character string “Great sale” to the variable str. In step S49, the code conversion unit 35 reads the character string up to the end tag corresponding to the block, and executes the processing after step S43 again.

  If it is determined in step S44 that the next tag is not a tag indicating the start of the object, or if it is determined in step S45 that the object is not a text string, the code conversion unit 35 The processing after step S49 is executed without changing the variables i and str. When such processing is executed for all the blocks, the code conversion unit 35 reads up to the tag and ends the series of processing. The QR code generated in this way is printed on the price tag table PT by the printer 5.

  As described above, according to the information processing system according to the first embodiment, since it is not necessary to download the format data itself to the mobile terminal 1, large format data is used regardless of the capacity of the mobile terminal 1. can do.

  Next, a detailed description will be given of a second embodiment of the information processing system according to the present invention. In addition, since the information processing system according to the second embodiment has the same configuration as the information processing system according to the first embodiment described above, detailed description thereof is omitted. Detailed explanation will be given only for the differences.

  Specifically, the portable terminal 201 constituting the information processing system includes a request accumulation unit 203 that accumulates request information, and a transmission instruction unit 205 that receives an instruction to transmit the request information accumulated by the user. Prepare. Such a portable terminal 201 stores the created request information in the request storage unit 203. When the user inputs a transmission instruction to the transmission instruction unit 205, the wireless communication unit 207 transmits all the request information stored in the request storage unit 203 to the information processing apparatus 209.

  Further, the information processing apparatus 209 includes a request buffer 211 that accumulates request information received by the receiving unit 41. The request buffer 211 stores request information received by the receiving unit 41. The request information stored in the request buffer 211 is sequentially read and analyzed by the request analysis unit 39.

  Hereinafter, the operation of the mobile terminal 201 will be described in detail with reference to FIG.

  When a series of processing starts, the portable terminal 201 analyzes the QR code in step S51, determines whether or not change information is input in step S52, and creates request information in step S53. In step S <b> 54, the mobile terminal 201 stores request information in the request storage unit 203. Then, the portable terminal 201 stands by until a transmission instruction is input to the transmission instruction unit 205 in step S55, and after the transmission instruction is input, the request information is transmitted in step S56 and the series of processing ends.

  Next, the operation of the information processing apparatus 209 will be described in detail with reference to FIG.

  When a series of processes starts, the information processing apparatus 209 determines whether request information is accumulated in the request buffer 211 in step S61. The information processing apparatus 209 repeatedly executes the same process until it is determined that the request information is accumulated. If it is determined that the request information is accumulated, the information processing apparatus 209 reads the request information accumulated in the request buffer 211 in step S62. When a plurality of pieces of request information are accumulated in the request buffer 211, the request analysis unit 39 sequentially reads, for example, request information with the oldest created date and time. The information processing apparatus 209 executes processes such as QR code generation and print data transmission in steps S63 to S69, similarly to the processes in steps S21 to S27 described above. Thereafter, in step S <b> 70, the information processing apparatus 209 determines whether there is request information in the request buffer 211. If there is request information in the request buffer 211, the information processing apparatus 209 executes the processing from step S63 onward again. On the other hand, when there is no request information in the request buffer 211, the information processing apparatus 209 ends the series of processes.

  As described above, according to the information processing system according to the second embodiment, the request information can be transmitted to the information processing apparatus 209 in a lump, and therefore compared with the information processing system according to the first embodiment. Thus, a series of processing can be performed more efficiently.

  The present invention is not limited to the above-described embodiment, and each configuration can be changed as appropriate without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the request information includes information that has not been rewritten by the user. However, the request information may include only a text string corresponding to the rewrite information. It is.

  Further, for example, in the above-described embodiment, the format data is stored in the format data storage unit 29. However, the storage destination of the format data and the product database is a server device connected via the network 7. Is also possible. Thereby, the format data and the product database can be shared by a plurality of information processing apparatuses. In this case, the format data reading unit 31 and the product data reading unit 45 acquire the format data or the product database from the server device by transmitting the document ID or the product ID to the server device via the network 7. When updating the product database, the product DB update unit 43 transmits the product ID and the content to be updated to the server device.
