And an outline of process control executed by the CPU 301 correspondingly.

  Reference is first made to FIG. When an operating voltage is applied to each part of the copying machine MF1 by turning on the power, the CPU 402 executes its own initialization and waits for initialization of other parts (step 1). When each part becomes ready, “input reading” ( In step 2), a user input to the copying machine MF1 is awaited, and if there is, it is read. In the following, the word “step” is omitted from the parentheses, and step no. Write numbers only. The operation board 10 automatically displays the copy input screen shown in FIG. 3 on the liquid crystal touch panel 11 immediately after its initialization. Thereafter, when a “read” instruction, a “print” instruction, a “facsimile” instruction, or the like is instructed by a user operation (touch) of the function selection key 14, an input screen for executing the instructed function is displayed on the liquid crystal touch panel 11. (3,4 / 11, 12/22, 23/37, 38).

In “input reading” (5) with the copy input screen displayed, the CPU 402 causes the operation board 10 to display the fax number input screen when a copy start is given by printing a fax (facsimile) number (destination). . In addition to using the numeric keypad 15, the fax number can be input by operating a registration number calling key or a shortened number designation key of a facsimile input board (not shown) on the left side of the liquid crystal display 11 (FIG. 3). (7). When the CPU 402 receives a fax number input completion notification from the operation board 10, the CPU 402 sends a fax number (text code) two-dimensional code (image data representing a code bar image) to the operation board 10 and the document accumulation control 430 (converter 420). ) indicating the conversion and storage in the local memory 40 7 to (8). Then, the CPU 301 and the document accumulation control 403 are instructed to copy with a two-dimensional code (Fax number) added (9). The image data read by the document scanner 100 is stored in the local memory 40 7 via the image input and output processing 302 and document storage control 403, the (image data of the header portion of the distal end of the 1-page image) the image data, A two-dimensional code image having a fax number is added. In this synthesis, the original image data in the header portion is discarded and a two-dimensional code image having a fax number is arranged instead. Image data having been subjected to the addition of the Fax number, via the document storage control 403 and image image output processing 302 is output to the printer 200. When a copy start with no fax number printing designation is given, the CPU 402 instructs the CPU 301 and the document accumulation control 403 to perform normal copying without image addition (10).

  The document scanner 100 of the MF1 is used by the user to print a sheet on which the setting parameters of the other multifunction copying machine MF2 are listed, converted into a two-dimensional code, and printed by processing equivalent to steps 31 to 34 shown in FIG. Is set as a reading document, “Read” (FIG. 3) is designated, and “Reading input screen” is displayed on the liquid crystal panel 11, “Change setting parameter by code reading” on the screen is displayed. When the reading start is instructed, the CPU 402 instructs the CPU 301 to read the original image, and the document storage control 403 sends the read image data to the text code (setting parameter) of the two-dimensional code (code bar) image. Is converted and stored in the local memory 409 (11 to 15). When this accumulation is completed, the operation board 10 displays an inquiry on whether to update the setting parameter on the panel 11, and when the user inputs OK to the screen, the settings stored in the local memory 409 by the CPU 402 and the operation board 10 respectively. The setting data of the HDD 401 and the nonvolatile memory in the board 10 is updated to the parameters (16, 17).

  Using this setting parameter update function, the user can port the setting parameters of another copier MF2 to MF1. Further, the setting parameters of the copying machine MF1 can be ported to another copying machine MF2.

  When the user instructs reading start by specifying “output of setting parameter list by code reading” instead of “changing setting parameters by code reading”, the CPU 402 instructs the CPU 301 to read a document image, and prints a document. The storage control 403 is instructed to convert the read image data into a text code (setting parameter) of a two-dimensional code (code bar) image and store it in the local memory 409 (11 to 15). When this accumulation is completed, the operation board 10 displays an inquiry as to whether or not to output the setting parameter difference list on the panel 11 and when the user inputs OK to the screen, the CPU 402 and the operation board 10 respectively enter the local memory 409. The difference between the accumulated setting parameters and the setting parameters of the HDD 401 and the nonvolatile memory in the board 10 is calculated and printed out as a list (readable character printing; 18 to 21).

Please refer to FIG. In “input reading” (24) in a state where the print input screen is displayed, the CPU 402 causes the operation board 10 to display the fax number input screen when the printing start is given by the fax (facsimile) number (transmission destination) printing designation. (26, 27). In addition to using the numeric keypad 15, the fax number can be input by operating the registration number calling key or the abbreviated number designation key of the facsimile input board (not shown) on the left side of the liquid crystal display 11 (FIG. 3). (27). When the CPU 402 receives a fax number input completion notification from the operation board 10, the CPU 402 sends a fax number (text code) two-dimensional code (image data representing a code bar image) to the operation board 10 and the document accumulation control 430 (converter 420). ) indicating the conversion and storage in the local memory 40 7 to (28). Then, the CPU 301 and the document accumulation control 403 are instructed to print with a two-dimensional code (Fax number) added (29). The image data to be printed that is stored in the local memory 40 7 or HDD 401 (image data of the header portion of the distal end of the 1-page image), is added a two-dimensional code image Fax number. In this synthesis, the original image data in the header portion is discarded and a two-dimensional code image having a fax number is arranged instead. The image data for which the Fax number has been added is output from the document storage control 403 and the image input / output process 302 to the printer 200. When a print start without a fax number printing designation is given, the CPU 402 instructs the CPU 301 and the document accumulation control 403 to perform normal printing without adding an image (30).

In “input reading” (24) with the print input screen displayed, when “parameter list output” is designated and print start is given, the CPU 402 lists the setting parameters registered in the HDD 401 and the operation board 10. storing in the local memory 40 7 and (31). When this is finished, the completion of list generation is notified to the panel 11 of the operation board 10, and a button for selecting one of “two-dimensional code printing” and normal “character printing” is displayed. When the user designates printing of a two-dimensional code and inputs execution, the CPU 402 instructs the CPU 301 and the document accumulation control 403 to convert and print the setting parameter list into a two-dimensional code (33). The two-dimensional code of the setting parameter list is output to the printer 200 via the document storage control 403 and the image input / output processing 302 (34).

When the user selects “character printing” instead of printing a two-dimensional code and inputs execution, the CPU 402 instructs the CPU 301 and the document accumulation control 403 to print the setting parameter list. Local memory 40 7 configuration parameter list, via the document storage control 403 and image output processing 302 is output to the printer 200 (35).

  As described above, the multi-function copying machine MF1 can select whether to print the contents of the list as characters or as a two-dimensional code image when outputting the list of setting parameters, and the user can select according to the purpose of use. , You can choose either one. When it is desired to visually check the setting contents, the character printing of the list is selected. When the setting contents are transferred to another apparatus, the two-dimensional code image printing is selected.

Please refer to FIG. When “facsimile” (FIG. 3) is designated and the facsimile input screen is displayed on the panel 11 and a start instruction is given, the CPU 402 sends a document to the ADF 120 on the contact glass of the document scanner 110 or the ADF 120 via the CPU 301. Is checked (37 to 41). Then, determination is made by referring to the setting information of the FCU 417 whether or not the fax number has been entered (designated). If the fax number has been entered, the CPU 301 and the document accumulation control 403 are instructed to read the document. The read image data accumulated in the local memory 40 7 (43), FCU417 transmits (44).

If the fax number has not been entered (designated), the CPU 402 instructs the CPU 301 and the document accumulation control 403 to read the document and recognize the fax number (45). The read image data is accumulated in the local memory 40 7, or image data of the page head of the header part is a two-dimensional code, determines the converter 420, the text encoding it to be of the two-dimensional code To the FCU 417 as a destination number (46, 47). FCU417 within facsimile earlier numbers Te該宛transmits the original read image data of the local memory 40 7 (48). When the converter 420 fails to detect the destination number, in response to this, the CPU 402 displays a destination number input guide on the operation board 10 (49). Sends a facsimile (48).

  When print information is received from outside (for example, a PC) and the print instruction is received, the CPU 402 converts the print information into bit image data for printing in the controller board 400 and outputs the bit image data to the printer 200 (50-26˜). 29). At this time, when the PC designates the fax destination number and instructs printing to add the fax number, the CPU 402 executes steps 26 to 29 in FIG. 5 to display the document information to which the two-dimensional code of the destination number is added. Print out.

  If the user installs a dedicated printer driver that can specify the fucksimile number on the PC, the user can specify the fucksimile number when printing the transmission document created with the word processor software of the PC with the copier MF1. The copying machine MF1 converts the facsimile number received from the PC into a two-dimensional code and adds it to the header area of the document information received together. In addition, you may make it add to a footer area | region.
