[0006]

Generally, a high-speed digital PPC having a copying ability of several tens or more sheets per minute is often installed in a common space such as a copying room or a corridor. When copying multiple copies of a document created on a personal computer, etc., the user outputs the original on a nearby printer,
This manuscript is brought to the place where the digital copying machine is installed, and a plurality of copies are copied using a sorter or the like in the digital copying machine. In particular, if the personal computer used by the user is a notebook type computer,
When not connected to the AN, the remote printing function of the digital copying machine cannot be used. In these cases, since the original image is output once on paper and then copied, there is a problem that image deterioration occurs.

On the other hand, when the user's personal computer is connected to the digital copying machine by LAN,
The user can use the remote print function provided in the digital copying machine. Therefore, the user can directly use the sorter function of the digital copying machine from his / her personal computer. However, even if the remote print function of the digital copying machine is used, in the end,
The user must go to a remote place where the digital copying machine is installed in order to take out the output printer. Furthermore, when a large number of copies are made using the remote print function, there is a high possibility that a paper jam or a recording paper break will occur in the digital copying machine. Therefore, even though the user uses the remote print function, the user needs to go to a remote place where the digital copying machine is installed. That is, the remote (online) printing function in a high-speed digital copying machine is
It can be said that this is a meaningless function.

Similarly, online from a user's personal computer using a parallel I / F or LAN,
When using the image scanner function of the digital copying machine, the user needs to set the document to be read on the image scanner section of the digital copying machine, so the user needs to go to a remote place of the digital copying machine. . That is, if the digital copier and the computer that is going to use its image scanner function are located far away from each other, connecting online is meaningless.

(Communication control unit) 82, compression / expansion circuit 86, PC card controller 88, etc.

The light emitted from the semiconductor laser 79 serves as a basis for forming an image on the recording paper by the method of a known laser printer. The CPU 85 has a RAM and a ROM (not shown) and controls the entire digital copying machine. The page memory 84 has a capacity capable of storing at least one page of image data and is connected to the buffer memory 74. The image data stored in the page memory 84 is output to the laser driver 78 via the buffer memory 74 and recorded on recording paper.

The LAN controller 80 is for communicating with an external device via a local area network (LAN). When the digital copying machine is used as a facsimile transmission server, an external device such as a computer transmits a destination telephone number and image data to the digital copying machine via LAN. The CPU 85 compresses the image data received from the external device via the LAN by the compression / expansion circuit 86 as necessary. A CCU (communication control unit) 82 uses a modem 87 to transmit the image data compressed by the compression / expansion circuit 86 to an external facsimile apparatus via a public line.

It is also possible to connect the digital copying machine and the external device in a one-to-one relationship by using the parallel I / F 81. In this case, it is possible to control the digital copying machine from a nearby computer. By executing the dedicated digital copying machine control software on the computer connected to the digital copying machine, for example, the number of copies / copies, recording paper size, copy density, enlargement ratio,
In addition to setting the copy mode such as the need for double-sided copying and the setting of the sorting method for the output recording paper, the presence or absence of frame erasing, the setting of the trimming area, the area setting of the editing processing such as negative / positive inversion, and the complicated image editing processing Settings can also be made using a computer display or mouse.

The image data received by facsimile is expanded by the compression / expansion circuit 86, transferred to the page memory 84, and printed out. Further, the original image data read for facsimile transmission is stored in the page memory 84.
After being stored in the
82 and the modem 87 to the external facsimile machine.

The PC card controller 87 is a CPU 85 of the memory card mounted in the PC card slot 89.
Access from. If a memory card mounted in the PC card slot 89 has a print job command file storing print output control information and an image data file to be printed, the digital copying machine of the present invention will operate based on the print output control information. ,
Print the image data. For digital copiers,
In many cases, the mounting status of optional equipment such as sorters and finishers and the edit functions that can be set differ depending on the option configuration. Therefore, it is preferable to store the function information included in the printer as a print function information file in the memory card. Details of this offline print function will be described later.

If a scan job command file in which read control information is stored is present in the memory card mounted in the PC card slot 89, the copying machine of the present invention is set based on the read control information. The read original image is read and stored in the memory card as an image data file. After the user sets the original, the user presses a start button (not shown) of the operation unit 300 to start reading the original. In the case of a digital copying machine, the mounting state of optional equipment such as an ADF and the image reading function often differ depending on the optional configuration. Therefore, the digital copying machine of the present invention stores the image reading function information provided as the image scanner in the memory card as the image reading function information file. Details of this offline image input function will be described later.

(Offline Print Function) Next, the offline print function in the digital copying machine of the present invention will be described. The user previously mounts his / her memory card on the digital copying machine of the present invention and downloads the print function information file to the memory card. The contents of the print function information file are shown in FIG. The contents of the print function information file shown in FIG. 3 will be described below.

The format of the print function information file is described for each line as follows. [Function item] [List of selectable functions] or [Function item] [Capability of function] The setting value written first in the list of selectable functions is the default value.

The meaning of each line of the print function information file shown in FIG. 3 is shown below. First line: The recording paper sizes are A4, A4R, B4, A3,
B5 and B5R can be set, and the default is A4. Second line: 400 DPI and 600 DPI can be selected as the recording resolution, and the default is 400 DPI. 3rd line: Gray level (number of data bits per pixel)

By default, single-sided printing is set. 7th line: There is a saddle-stitch printing function. When the saddle-stitch printing function is used, the order of pages to be printed can be rearranged, and two pages can be printed on one side of a recording paper having an area size twice as large as the image data, and saddle-stitching can be performed. By default, the saddle stitch function is not used. Line 8: By setting the operation of the sorter, it is possible to specify either not using the sorter, stacking for each page, or collating by copy. The default setting is sorter not used. 9th line: Indicates that the number of paper discharge trays (bins) of the sorter is 20. You cannot collate more than 20 copies on the sorter. 10th line: indicates the maximum number of recording sheets that can be stacked in each bin when the sorter function is used. 11th line: The presence or absence of staple (stapling) can be designated. 12th line: It is possible to specify a stopping position when stapling, and one of four types 1 to 4 can be selected.
The default is one. FIG. 4 shows the relationship between the stapling position and the designated number. 13th line: indicates the maximum number of recording sheets that can be stapled when the staple function is used. Line 14: The presence or absence of punching can be specified. The default is no punch. Fifteenth line: indicates the maximum number of recording sheets that can be punched when the punching function is used.

A user creates a document / image using a document / image creating application software such as a word processor or DTP (Desktop Publishing) software executed on a personal computer.
The printer driver software for the digital copying machine of the present invention is installed in advance in the personal computer used by the user. When offline printing of a user-created document or image using the digital copying machine of the present invention, a memory card having the print function information file downloaded is mounted on the user's personal computer. The user activates the printer driver from the document / image creation application software. The printer driver refers to the print function information file stored in the memory card and displays a dialog box for allowing the user to set the print function of the digital copying machine on the display of the personal computer.

Next, FIG. 5 shows a schematic display of the dialog box corresponding to the print function information file shown in FIG. In FIG. 5, START Page-E
NDPage, Copies and Data File
The rectangular area on the right side of the word Name is an edit box, and the print start page, end page, the number of copies, and the image data file name are input. The circles in the other lines are radio buttons that are selected by alternative. ●
The mark indicates the selected item. Only when TIFF is selected as the image data file format,
The selection item of TIFF Compression is valid. When it is set to use the sorter in the dialog box, the printer driver checks the values of Max Sort and Max Stack in the print function information file, and warns the user if they conflict with the settings of the number of print copies and the number of pages. Similarly, when the staple function or the punch function is used, Max Style Sheets or Max Pun of the print function information file is used.
The value of ch is checked, and if it conflicts with the setting of the number of print copies or the number of pages, the user is warned.

After setting each item in the dialog box, the user clicks the OK button in FIG. 5 with the mouse. The printer driver creates a print job command file and an image data file based on the settings in the dialog box and stores them in the memory card.
FIG. 6 shows the contents of the print job command file corresponding to the settings in the dialog box of FIG. First line (Reset) of the print job command file in FIG.
Indicates that the print function setting value is reset to the default value. The item of Data File describes the image file name to be printed. In the case of FIG. 5, the image file name is sample. tif. In the image file, multi-page (plural pages) images are stored in one file. The print job command file can combine a plurality of jobs into one file. That is, a plurality of image files can be output with different print function settings.

FIG. 7 shows a flowchart of the process of the printer driver. The printer driver reads the print function information file from the memory card and displays a dialog box for print function setting based on the read file.
The user clicks the OK button after setting each setting item in the dialog box. The printer driver checks the settings in the dialog box for inconsistencies, displays a warning if there is an inconsistency, and prompts the user to reset the dialog box. If there is no contradiction, a print job command file and an image data file are created and stored in the memory card.

The user pulls out the memory card storing the print job command file and the image data file from the user's personal computer and inserts it in the PC card slot 89. The CPU 85 detects that a memory card has been inserted via the PC card controller 87, and searches for a print job command file in the memory card. When the print job command file exists, the CPU 85 analyzes the print job command file and makes necessary settings for the control circuit (not shown) of the laser printer unit and the sorter unit. C
The PU 85 refers to the image data file name in the print job command file, reads the image data file from the memory card, and prints it. When the image data is compressed, the CPU 85 uses the compression / expansion circuit 86 to expand the image data in the page memory 84. When saddle stitching or the like is performed, the page order of the image data file and the printing order are not the same, so the CPU 85 controls to print each page in the image data file in an appropriate order. When all the print outputs specified in the print job command file are completed, the CPU 8
Reference numeral 5 erases the print job command file and the image data file stored in the memory card.

Image data such as a document created by a personal computer or the like and output control data (print job command file) of the image data are generated and stored by a user's personal computer in a removable recording medium, and this storage medium is stored in a PC. By mounting in the card slot 89, the image data stored in the storage medium can be output offline in a desired output form. Therefore, the user can specify the number of copies and the sorting or stapling method at the time of creating a document or the like on a personal computer. Therefore, it is no longer necessary to print with a printer near by and copy the printed document as in the conventional case, and the image quality of the copy is not deteriorated. Particularly, in the case of a notebook type computer, it is often not connected to an external device via a LAN or the like in order to make it portable. Even in such a case, according to the digital copying machine of the present invention, it is possible to easily perform offline printing using a memory card or the like.

Furthermore, in the case of a high speed copying machine, the configuration of optional equipment such as a sorter and finisher varies,
It is difficult to specify the print function of the copying machine. FIG. 8 shows the configuration of a digital copying machine in which a finisher 222 is mounted instead of the sorter 221 in the schematic configuration diagram of FIG. The finisher is a device that staples the sheets after stacking them in units, and in particular, in a digital copying machine, an electronic finisher is used to perform collation in units of units instead of a sorter. The electronic finisher is provided with a large-capacity storage means such as a hard disk device in a digital copying machine, temporarily stores image data of read originals of a plurality of pages, prints in sets, and collates in sets. Therefore, a mechanical sorter becomes unnecessary.

Instead of the sorter 221, the finisher 222
When the is installed in a digital copying machine, a hard disk device is also added to the digital copying machine. Some finishers have a function of folding the printed recording paper. Further, double-sided printing may not be possible unless an optional device called an automatic double-sided unit is attached to the digital copying machine. As described above, depending on the mounting state of the optional equipment of the copying machine, the printing output function of the copying machine may differ even if the main body is the same model. Since the digital copying machine of the present invention can download the print function information of the copying machine to the storage medium, the user can use all the printing functions of the digital copying machine.

(Offline Image Input Function) Next, the offline image input function in the digital copying machine of the present invention will be described. The user previously mounts his / her memory card on the digital copying machine of the present invention and downloads the reading function information file to the memory card. The contents of the reading function information file are shown in FIG. The contents of the reading function information file shown in FIG. 9 will be described below.

The format of the reading function information file is described as follows for each line. [Function item] [List of selectable functions] or [Function item] [Capability of function] The setting value written first in the list of selectable functions is the default value.
