Description

  The present invention relates to a facsimile apparatus, and more particularly to a facsimile apparatus that converts text data representing text input from an operation unit into image data and transmits / receives the image data.

  As a conventional facsimile apparatus, there is an apparatus that converts text data representing a text (character string) input from an operation unit into image data, encodes it, and transmits it as a facsimile document. This apparatus has a feature that it can easily send a document including only figures (consisting only of character strings) to the counterpart facsimile apparatus without using paper.

  As a conventional facsimile apparatus, there is a color facsimile apparatus that can transmit a color image.

  Further, although not a facsimile machine, in the field of computers, a tag representing character modification information of a character string is inserted into text data representing a character string, and the text data into which the tag has been inserted is loaded with predetermined application software. There is a technique for displaying a character string that has been character-modified by using it and displaying it on a display unit. In this technology, text data with a tag inserted is transmitted to another computer through a network or the like, so that the other computer can use the same or the same type of application software to display the character-modified character string on the screen of the display unit. Can be displayed on top and printed.

  A conventional facsimile apparatus that converts text data input from the operation unit into image data, encodes it, and transmits it as a facsimile document can only transmit monochrome image data. There is a problem that character modification cannot be performed.

  The above problem can be solved by using the technology used in the color facsimile apparatus. In this case, however, data corresponding to the three primary colors is required, so that the amount of data to be transmitted is larger than that in the case of monochrome. Another problem arises in that simple calculation results in a triple, transmission efficiency and processing efficiency decrease, and convenience decreases.

  Further, the method of inserting a tag into text data used in the computer field has a problem that it cannot be applied as it is to a facsimile apparatus that converts text data into image data and performs transmission / reception.

  First, with reference to FIG. 1 and FIG. 2, text input / editing when the facsimile apparatus 10 is a transmission side will be described.

  When the operator operates the operation unit 12 to select a character input / edit mode, text can be input / edited from the operation unit 12. The main control unit 11 controls the display unit 13 in accordance with the input from the operation unit 12 to display the input text, and stores text data representing the text in the text data storage unit 192. When text is input from the operation unit 12 in this way, the input text is displayed on the screen of the display unit 13 as shown in FIG. The text data storage unit 192 stores text data representing the text displayed on the display unit 13. At this time, when the text data stored in the text data storage unit 192 is represented in a visible form, it is as shown in FIG. Note that the text display color is black in the default state. In FIG. 2B-1, the bent arrow represents “new line”.

  Next, when the operator operates the operation unit 12 and performs character modification (font change, style change, color change, indent, etc.) on the character to be input thereafter, the text data stored in the text data storage unit 192 is stored. Is added with a tag indicating that character modification is performed on the subsequent characters. FIG. 2B-2 shows a state where a tag “$ RED $” indicating that the character color has been changed to red (representing the starting point of the red character) is added. At this time, the display on the display unit 13 does not change as shown in FIG.

  Subsequently, when the operator inputs text from the operation unit 12, the display on the display unit 13 is as shown in FIG. 2A-3 (here, the white characters represent red characters). In addition, data corresponding to the input text is also added to the text data storage unit 192.

  Next, when the operator operates the operation unit 12 and sets the color of the character to be input thereafter to the default (black), the tag “indicating the end point of the red character is stored in the text data stored in the text data storage unit 192. “$ / RED $” is added. At this time, the display on the display unit 13 does not change as shown in FIG. Thereafter, when text is input from the operation unit 12, the input text is displayed in black on the display unit 13, and data corresponding to the input character is added to the text data stored in the text data storage unit 192. The

  As described above, when the operator inputs text from the operation unit 12, text data corresponding to the text data storage unit 192 is stored. When character modification such as designating the color of the character is performed during text input, a tag is inserted into the text data as the corresponding character modification information.

  In the above description, “$” is used as a symbol indicating a tag, but other symbols may be used as long as the symbol is not a symbol that can be input as text from the operation unit 12.

  Next, the transmission operation of the facsimile machine 10 will be described with reference to FIGS.

  After the input of the text data as described above is finished in step S301, when the transmission execution instruction is given from the operation unit 12 as well, the facsimile apparatus 10 starts the transmission operation (step S302).

  More specifically, the main control unit 11 receives a communication start instruction from the operation unit 12 and instructs the communication control unit 14 to start communication. Upon receiving an instruction from the main control unit 11, the communication control unit 14 calls the partner facsimile machine (sends a CNG signal periodically). After receiving the call (after transmitting the CED signal), the partner facsimile apparatus transmits predetermined information (NSF signal, CSI signal, DIS signal) in accordance with the normal facsimile communication procedure.

  Upon receiving predetermined information from the partner facsimile machine, the communication control unit 14 recognizes the attribute of the partner facsimile machine and determines whether or not the partner facsimile machine has a tag analysis capability, that is, has the same configuration as the own machine. It is determined whether or not (step S303). As a result, when it is determined that the partner facsimile apparatus has the tag analysis capability, the partner facsimile apparatus is notified that the tagged document is to be transmitted (in addition to the TSI signal, the NSS with the tagged document sending bit turned ON). A signal is transmitted) (step S304), and this is also notified to the main control unit 11. On the other hand, if it is determined that the partner facsimile machine does not have tag analysis capability, the communication control unit 14 notifies the partner facsimile machine that a normal document that does not include a tag is to be transmitted (tagged document). The NSS signal with the sending bit turned off is transmitted), and the main controller 11 is requested to delete the tag (step S305).

  When the main control unit 11 receives a notification from the communication control unit 14 that the counterpart facsimile has the tag analysis capability, the main control unit 11 reads the text data stored in the text data storage unit 192 and reads the image data generation unit. Send to 16. On the other hand, the main control unit 11 that has received a notification from the communication control unit 14 that the partner facsimile does not have tag analysis capability sends the text data read from the text data storage unit 192 to the tag analysis unit 15, Command to delete.

  Upon receiving the tag deletion command, the tag analysis unit 15 detects and deletes the portion corresponding to the tag from the input text data. Then, the tag analysis unit 15 outputs the text data from which the tag is deleted to the image data generation unit 16.

  The image data generation unit 16 generates image data from the input text data (converts the text data into image data), and outputs it to the main control unit 11. The main control unit 11 encodes the input image data with the CODEC 111 to form a facsimile document (encoded image data), and outputs the facsimile document to the communication control unit 14. The communication control unit 14 transmits the facsimile document to the partner facsimile machine via the modem 21 and the NCU 20 (step S306).

  As described above, when the partner facsimile machine has the tag analysis capability, the facsimile machine 10 converts the text data containing the tag into image data, encodes it, and sends it to the partner facsimile machine. If the tag analysis capability is not provided, the text data from which the tag is deleted is converted into image data, encoded and transmitted. As a result, transmission of a facsimile document (encoded image data) including a tag representing character modification information to a facsimile apparatus having no tag analysis capability is prevented.

  Next, the reception operation of the facsimile apparatus 10 will be described with reference to FIGS.

  When the communication control unit 14 receives a call from the outside via the NCU 20 and the modem 21, it automatically responds to it and starts communication (step S501). Then, the communication control unit 14 notifies the transmission side facsimile apparatus of the attributes of the own apparatus. At that time, the communication control unit 14 notifies the transmitting-side facsimile apparatus that it has tag analysis capability (transmits an NSF signal with the tag analysis capability bit turned on) (step S502).

  Next, the communication control unit 14 determines whether or not the document sent thereafter is a tagged document based on the information (NSS signal described above) transmitted from the transmitting facsimile machine (step S503). ). The result of the determination is transmitted to the main control unit 11.

  Thereafter, the communication control unit 14 sends the facsimile document received via the NCU 20 and the modem 21 to the main control unit 11. Based on the determination result previously notified from the communication control unit 14, the main control unit 11 distinguishes the received facsimile document into a tagged document and an untagged document and stores them in the encoded data storage unit 191 (step S504). , S505).

  After completing the reception of the facsimile document, the communication control unit 14 ends the communication (step S506).

  Next, the output operation of the received facsimile document will be described with reference to FIGS.

  When the operator operates the operation unit 12 to make an output request for the received facsimile document (step S601), the main control unit 11 determines whether or not the document requested for output is a tagged document (step S601). S602).

  When the output request target document is a tagged document, the main control unit 11 reads the document from the encoded data storage unit 191, decodes it with the CODEC 111, and converts the decoded image data into the image-text conversion unit 17. To supply. The image-text conversion unit 17 converts the supplied image data into text data using a character recognition description or the like (step S603). The obtained text data is temporarily stored in the text data storage unit 192.

  Next, the main control unit 11 determines an output destination. Here, a case will be described in which the display unit 13 has a color display function and the recording unit 18 has a monochrome output function. However, when the recording unit 18 has a color output function, output to the display unit 13 is performed. It becomes the same as the case of doing.

  When outputting the received document to the display unit 13 having the color output function, the main control unit 11 passes the text data stored in the text data storage unit 192 to the tag analysis unit 15 and instructs the analysis of the tag. The tag analysis unit 15 detects and analyzes the tag from the input text data, and generates screen display data that is displayed on the display unit 13 in a state where the character modification represented by the tag is applied to the text. And it outputs to the display part 13 (step S605). The display 13 displays the text including the character-modified character on the screen based on the screen display data from the tag analysis unit 15.

  On the other hand, when the received document is output to the recording unit 18 that does not have the color output function (only the monochrome output function), the main control unit 11 uses the text data stored in the text data storage unit 192 as the tag analysis unit 15. Pass and command tag analysis. Upon receiving the command, the tag analysis unit 15 detects and removes the tag from the input text data. Then, the tag analysis unit 15 outputs the text data from which the tag has been removed to the image generation unit 16. The image generation unit 16 generates image data based on the input text data (step S606). The main control unit 11 delivers the image data generated by the image generation unit 16 to the recording unit 18. The recording unit 18 performs printing based on the input image data.

  On the other hand, if it is determined in step S602 that the output request target document is an untagged document, the main control unit 11 reads the document from the encoded data storage unit 191, decodes it with the CODEC 111, and displays the display unit. 13 or the recording unit 18. The display unit 13 and the recording unit 18 perform screen display or printing based on the input decoded image data (step S607).

  While the present invention has been described with reference to one embodiment, the present invention is not limited to the above embodiment. For example, in the above embodiment, a case has been described in which tabs are inserted into text data input from the operation unit for transmission / reception, but image data read by a scanner or the like may be converted into text data.
