Description

  The present invention relates to a digital copying machine, and more particularly to a digital copying machine and an image reading apparatus that can use an image input / output function offline using a removable storage medium.

  In recent years, digital copiers are required to have high speed and multiple functions, and so-called digital multi-function machines in which a facsimile function and a printer function are added in addition to a copying function have appeared. A conventional digital copying machine will be described below with reference to the drawings.

  FIG. 13 is a block diagram showing the flow of image signals in a conventional digital copying machine. The conventional digital copying machine shown in FIG. 13 scans a document and converts reflected light from the document into an electrical signal, and an A / D that converts an analog image signal from the image sensor 71 into a digital image signal. A converter 72; an image processing circuit 73 for performing image processing such as edge enhancement, trimming, halftone processing and editing processing on the digital image signal; and an image signal from the image processing circuit 73 is buffered, and a laser driver 78, a buffer memory 74 for adjusting the speed for output to 78, a laser driver 78 for driving the semiconductor laser 79, a CPU 85, a LAN controller 80, a page memory 84, a parallel I / F 81, connected by a CPU bus 83, Consists of CCU (communication control unit) 82 and compression / decompression circuit 86 It has been.

  The light emitted from the semiconductor laser 79 becomes a basis for forming an image on a recording sheet by a known laser printer method. The CPU 85 includes 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 the 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 remote printer, an external device such as a computer transmits a print control command and image data to the digital copying machine via a LAN. The CPU 85 expands the image data received via the LAN in the page memory based on the received print control command. It is also possible to connect a digital copying machine and an external device on a one-to-one basis using a parallel I / F 81. In this case, when the digital copying machine is used as a printer of an external device, the external device transmits a print control command and image data to the digital copying machine via the parallel I / F of the digital copying machine.

  The CCU 82 uses the modem 87 to communicate with an external facsimile apparatus via a public line. The image data received by facsimile is decompressed by the compression / decompression circuit 86, transferred to the page memory 84, and printed out. The original image data read for facsimile transmission is stored in the page memory 84, compressed by the compression / decompression circuit 86, and transmitted to the external facsimile apparatus via the CCU 82 and the modem 87. When the image scanner function of the digital copying machine is used from an external device, the external device transmits a document reading control command to the digital copying machine via the parallel I / F 81, and the read document image data is externally transmitted from the digital copying machine. Send to device.

  In general, a high-speed digital PPC having a copying capacity of several tens or more 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 with a personal computer, the user outputs a manuscript with a nearby printer, takes the manuscript to the place where the digital copier is installed, and places a sorter with the digital copier. A plurality of copies will be made using it. In particular, when the personal computer used by the user is a notebook type or the like and is not connected to the LAN, the remote print function provided in the digital copying machine cannot be used. In these cases, since the original image is once printed on paper and then copied, there is a problem that the image is deteriorated.

  On the other hand, when the user's personal computer is connected to the digital copying machine via a LAN, the user can use the remote printing function of the digital copying machine. Accordingly, the user can directly use functions such as a sorter of the digital copying machine directly from his / her personal computer. However, even if the remote printing function of the digital copying machine is used, the user eventually has to go to the installation site of the digital copying machine at a remote location in order to take out the output of the printer. Further, when a large amount of copying is performed using the remote print function, there is a high possibility that a paper jam or a recording paper break will occur in a digital copying machine. Therefore, it is necessary for the user to go to a place where the digital copying machine is located at a remote location, even though the user uses the remote print function. That is, it can be said that the remote (online) printing function in a high-speed digital copier is a function that does not make much sense.

  Similarly, when using the image scanner function of the digital copying machine online from the user's personal computer using a parallel I / F or LAN, the user needs to set the read document in the image scanner section of the digital copying machine. For this reason, the user needs to go to a place where the digital copier is located at a distance. In other words, when the digital copying machine and the computer where the image scanner function is to be used are separated, online connection is not very meaningful.

The laser printer unit 200 includes a laser scanner unit 201 including a semiconductor laser, a polygon motor, a polygon mirror, and a laser optical system (not shown), a mirror 202, a photosensitive drum 203, a main charger 204, and a development unit. 205, transfer charger 206, cleaner 207, static elimination lamp 208, conveying belt 209, fixing device 210, guide 211, paper discharge roller 212, paper feed rollers 213, 214 and 215, guide 216, a timing roller 217, recording paper cassettes 218, 219, and 220, a sorter 221 and the like.

  The basic operation as a copying machine in the digital copying machine configured as described above will be described. A plurality of documents placed on the ADF 50 are placed downward on the document table 1 made of a transparent glass plate one by one by the ADF. The exposure lamp 101 exposes the document. The first mirror 102 reflects the reflected light from the document in the direction of the second mirror 104. A constant velocity unit 103 comprising an exposure lamp 101 and a first mirror 102 moves at a constant speed in the direction of arrow P, and scans a document. The second mirror 104 and the third mirror 105 further reflect the reflected light from the first mirror 102. The half speed unit 106 composed of the second mirror 104 and the third mirror 105 moves in the same direction as the constant speed unit 103 at half the speed of the constant speed unit 103. The reflected light from the document is focused by the lens 107 and focused on the image sensor 108. The photosensitive drum 203 rotates in the direction of arrow R at a constant speed. The main charger 204 uniformly charges the photosensitive drum 203. The laser light emitted from the laser scanner unit 201 is reflected by the mirror 202, and the photosensitive drum 203 is exposed and scanned to form an electrostatic latent image on the photosensitive drum 203. The developing unit 205 develops the electrostatic latent image with toner and forms a toner image on the photosensitive drum 203.

  Each of the recording paper cassettes 218, 219, and 220 is detachable, and holds recording papers of different sizes within a predetermined number according to the required size and direction. The paper feed rollers 213, 214, and 215 feed the recording paper in the recording paper cassette one by one. The guide 216 guides the fed recording paper and guides it to the timing roller 217. The timing roller 217 performs registration for aligning the fed recording sheet with the toner image on the photosensitive drum 203 and adjusts the feeding timing. The toner image on the photosensitive drum 203 is transferred to the recording paper by the electric field generated by the transfer charger 206. The conveyance belt 209 moves in the direction of arrow Q and conveys the recording paper to the fixing device 210. The fixing device 210 fixes the toner on the recording paper to the recording paper by heat. The guide 211 guides the recording paper from the fixing device 210 to the paper discharge roller 212. The paper discharge roller 212 guides the recording paper from the fixing device 210 to the sorter 221. The sorter 221 includes a plurality of paper discharge trays (bins), and performs collation at the time of copying in units of copies. The sorter 221 has a staple (stapling) function and a punch function. The cleaner 207 removes the toner remaining on the photosensitive drum 203 from the photosensitive drum 203. The static elimination lamp 208 erases the charge on the photosensitive member by exposing the photosensitive drum 203.

  Next, a configuration based on the image signal flow of the digital copying machine of FIG. 1 will be described with reference to FIG. As shown in FIG. 2, the digital copying machine has an image sensor 71 that scans a document and converts reflected light from the document into an electrical signal, and an A / A that converts an analog image signal from the image sensor 71 into a digital image signal. A D converter 72, an image processing circuit 73 for performing image processing such as edge enhancement, trimming, halftone processing, and editing processing on the digital image signal; and an image signal from the image processing circuit 73 is buffered, and laser Buffer memory 74 for speed adjustment for output to driver 78, laser driver 78 for driving semiconductor laser 79, CPU 85, LAN controller 80, page memory 84, parallel I / F 81 connected by CPU bus 83 , CCU (communication control unit) 82, compression / decompression circuit 86, PC car It is composed of the controller 88 or the like.

  The light emitted from the semiconductor laser 79 becomes a basis for forming an image on a recording sheet by a known laser printer method. The CPU 85 includes 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 the 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 a LAN. The CPU 85 compresses the image data received from the external device via the LAN by the compression / decompression circuit 86 as necessary. A CCU (communication control unit) 82 uses the modem 87 to transmit the image data compressed by the compression / decompression circuit 86 to the external facsimile apparatus via the public line.

  Note that it is also possible to connect the digital copying machine and the external device on a one-to-one basis using the parallel I / F 81. In this case, the digital copying machine can be controlled from a nearby computer. By executing dedicated digital copier control software on a computer connected to the digital copier, for example, the number of copies / number of copies, recording paper size, copy density, enlargement ratio, and the need for double-sided copying are not necessary and output. In addition to copying mode settings such as the sorting method for recording paper to be printed, complex image editing processing settings such as the presence / absence of frame erasing, trimming area setting, area setting for editing processing such as negative / positive reversal, etc. It becomes possible using.

  The image data received by facsimile is decompressed by the compression / decompression circuit 86, transferred to the page memory 84, and printed out. The original image data read for facsimile transmission is stored in the page memory 84, compressed by the compression / decompression circuit 86, and transmitted to the external facsimile apparatus via the CCU 82 and the modem 87.

  The PC card controller 87 controls access from the CPU 85 of the memory card installed in the PC card slot 89. When a print job command file in which print output control information is stored and an image data file to be printed exist in a memory card mounted in the PC card slot 89, the digital copying machine of the present invention is based on the print output control information. Print image data. In the case of a digital copying machine, the mounting state of optional equipment such as a sorter and finisher and editable functions that can be set often vary depending on the option configuration. For this reason, it is preferable to store function information provided as a printer in a memory card as a print function information file. Details of the offline print function will be described later.

  If a scan job command file in which read control information is stored is present in a memory card mounted in the PC card slot 89, the copying machine of the present invention can set a document image set on the basis of the read control information. Is 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 an optional device such as an ADF and the image reading function often vary depending on the option configuration. For this reason, the digital copying machine of the present invention stores image reading function information provided as an image scanner in the memory card as an image reading function information file. Details of the offline image input function will be described later.

(Offline print function)
Next, the off-line print function in the digital copying machine will be described. The user inserts his / her memory card in the digital copying machine in advance 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 as follows for each line.
[Function items] [List of selectable functions]
Or
[Function items] [Function capabilities]
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: A4, A4R, B4, A3, B5, and B5R can be set as the recording paper size, 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 row: Gray level (number of data bits per pixel) can be selected from 1, 2, 4, 8 bits, and the default value is 1 bit.

  Fourth line: TIFF, JPRG, and PCL5 can be selected as the image data file format, and the default is TIFF.

  5th line: When TIFF is selected as the image data file format, G3 (MH), G4 (MMR), RLE (run length), and LZW can be selected as the data compression method, and the default is G3.

  6th line: There is a double-sided printing function, and the necessity of double-sided printing can be set. By default, single-sided printing is set.

  Line 7: A saddle stitch printing function is provided, and when the saddle stitch printing function is used, the pages can be rearranged and printed on a recording sheet having an area size twice as large as the image data, so that two pages can be printed on each side. By default, the saddle stitch function is not used.

  8th line: In the sorter operation setting, it is possible to designate either sorter non-use, stack for each page, or collation for each unit. The default setting is no sorter.

  Ninth line: indicates that the number of the discharge trays (bins) of the sorter is 20. You cannot collate more than 20 parts on a sorter.

  10th line: When the sorter function is used, the maximum number of recording sheets that can be stacked in each bin is shown.

  11th line: The presence or absence of stapling (stapling) can be specified.

  12th line: The stop position for stapling can be specified, and one of four types 1 to 4 can be selected. The default is 1. FIG. 4 shows the relationship between the stapling position and the designated number.

  13th line: When the stapling function is used, the maximum number of recording sheets that can be stapled is shown.

  14th line: The presence or absence of punching (drilling) can be specified. The default is no punch.

  15th line: Indicates the maximum number of recording sheets that can be punched when the punch function is used.

  The user creates a document / image using document / image creation 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 a personal computer used by the user in advance. When a user-created document or image is printed off-line using the digital copying machine of the present invention, a memory card having a print function information file downloaded is loaded into 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, a rectangular area on the right side of the characters “START Page-END Page”, “Copies”, and “Data File Name” is an edit box for inputting a print start page, an end page, the number of copies, and an image data file name. The circles in the other rows are radio buttons that can be selected by alternative. ● indicates items that have been selected. Only when TIFF is selected as the image data file format, the selection item of TIFF Compression is effective. If the sorter is set to be used in the dialog box, the printer driver checks the value of Max Sort or Max Stack in the print function information file, and warns the user if it is inconsistent with the setting of the number of copies or pages. Similarly, when using the staple function or the punch function, the value of Max Staple Sheets or Max Punch in the print function information file is checked, and the user is warned if there is a contradiction with the setting of the number of copies or the number of pages.

  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. The first line (Reset) of the print job command file in FIG. 6 indicates that the print function setting value is reset to the default value. In the “Data File” section, the name of an image file to be printed is described. In the case of FIG. 5, the image file name is sample. tif. In the image file, a multi-page (multiple page) image is 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.

  A flowchart of the process of the printer driver is shown in FIG. The printer driver reads the print function information file from the memory card, and displays a print function setting dialog box based on the read file. The user clicks an OK button after setting each setting item in the dialog box. The printer driver checks whether there is a contradiction in the dialog box settings, displays a warning if there is a contradiction, 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 extracts the memory card storing the print job command file and the image data file from the user's personal computer and inserts it into 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 on 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. The CPU 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 expands the image data in the page memory 84 using the compression / decompression circuit 86. When performing saddle stitch printing or the like, 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 85 deletes 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 in a removable recording medium from the user's personal computer, and this storage medium is stored in the PC card slot 89. It is possible to output the image data stored in the storage medium offline in a desired output form. Therefore, the user can specify the number of copies and the sorting or stapling method at the time when the document is created by the personal computer. For this reason, it is not necessary to print with a nearby printer once as in the prior art, and it is not necessary to copy the printed document, and there is no deterioration in the image quality of the copy. In particular, notebook type computers are often not connected to external devices via a LAN or the like in order to be portable. Even in such a case, according to the digital copying machine of the present invention, offline printing can be easily performed using a memory card or the like.

  Furthermore, in the case of a high-speed copying machine, the configuration of optional devices such as a sorter and a finisher is various, so it is difficult to specify the printing function of the copying machine. In the schematic configuration diagram of FIG. 1, FIG. 8 shows the configuration of a digital copier equipped with a finisher 222 instead of the sorter 221. As shown in FIG. A finisher is a device that stacks and then staples in units of copies. In particular, in a digital copying machine, an electronic finisher is used to collate in units of units instead of a sorter. The electronic finisher has a large-capacity storage means such as a hard disk device in the digital copying machine, temporarily stores the read image data of a plurality of pages of the document, performs printing in units of copies, and performs collation in units of copies. This eliminates the need for a mechanical sorter.

  When the finisher 222 is attached to the digital copying machine instead of the sorter 221, a hard disk device is also added to the digital copying machine. Some finisher functions have a function of folding printed recording paper. In some cases, duplex printing cannot be performed unless an optional device called an automatic duplex unit is installed in the digital copying machine. As described above, depending on the mounting state of the optional device of the copying machine, the print output function of the copying machine may be different even if the main body is the same model. Since the digital copying machine of the present invention can download the printing function information possessed by the copying machine to a storage medium, the user can use all the printing functions possessed by the digital copying machine.

(Offline image input function)
Next, the offline image input function in the digital copying machine will be described. The user inserts his memory card in the digital copying machine in advance, 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.

  13th line: A reading area can be specified. The default is a setting that does not specify a reading area (reads the entire document size).

  14th line: The designated unit of the reading area is millimeter (mm).

  In the case of off-line printing using a digital copying machine, the user attaches the memory card having the reading function information file downloaded to his / her personal computer. The user executes scan job command file creation software for a digital copying machine that is installed in advance in a personal computer used by the user. This software refers to the reading function information file stored in the memory card, and displays a dialog box for allowing the user to set the reading function of the digital copying machine on the display of the personal computer.

  FIG. 10 shows a schematic display of a dialog box corresponding to the reading function information file shown in FIG.

The user extracts the memory card storing the scan job command file from the user's personal computer and inserts it into the PC card slot 89 of the digital copying machine of the present invention. The CPU 85 detects that a memory card has been inserted via the PC card controller 87, and searches for a scan job command file on the memory card. When the scan job command file exists, the CPU 85 analyzes the scan job command file and makes necessary settings for the control circuit (not shown) and the image processing circuit 73 of the image scanner unit and the ADF 50 unit. The read document image data is stored in the page memory 84. The CPU 85 uses the compression / decompression circuit 86 to compress the image data stored in the page memory, and stores the compressed image data in the memory card with the image data file name specified in the scan job command file.

  The user removes the memory card storing the image data file from the digital copying machine and attaches it to the user's personal computer. The user accesses the image data stored in the memory card using document creation / image editing software executed on a personal computer.

  As described above, when the image input function of a digital copying machine is used, document reading control data (scan job command file) is stored in a removable recording medium, and this storage medium is stored in the PC card slot of the digital copying machine. Attach to. Accordingly, the digital copying machine can output the read image data in the desired reading form to the storage medium offline, and the user can easily create the read control data using the user interface of the personal computer. In particular, notebook computers are often not directly connected to external devices in order to be portable. Even in such a case, according to the digital copying machine of the present invention, it is possible to easily read an original image offline using a memory card or the like.

  Furthermore, in the case of a copying machine, the configuration of optional devices such as the presence or absence of ADF, the function of ADF (whether double-sided scanning is possible, whether or not there is an automatic document size detection function, etc.), and the presence or absence of a slide reader are various. It is difficult to specify the image reading function of the copying machine. Even if the main body is the same model, the image reading function of the copying machine varies depending on the mounting state of optional devices of the copying machine. However, the user can use all of the image reading functions of the digital copying machine by downloading the image reading function information of the copying machine to the storage medium.

  In the above embodiment, a memory card is used as a removable storage medium, but the same effect can be obtained by using a floppy (registered trademark) disk, an optical disk, a removable hard disk, or the like. In the above embodiment, the case of a monochrome digital copying machine has been described. However, the same applies to a color copying machine. Furthermore, in the above embodiment, the function information file and job command file are character data files, but may be files encoded into binary data.

  The digital copying machine and the image reading apparatus according to the present invention personalize reading control information (number of reading gradations, reading size, image compression method, edge enhancement amount, contrast, reading density, image data file name, etc.) in the image scanner. It is stored in a removable storage medium using software that can be executed by a computer, etc., and this storage medium is attached to the digital copying machine, and a reading document is set in the digital copying machine, and the reading stored in the storage medium is performed. The original image is read in accordance with the control information, and the image data is output to a storage medium offline. The user can reattach the storage medium to the user's personal computer, etc., and read the stored image data to perform desired processing. Has an off-line image input function And copy machine, can be applied to applications where such the location of the computer to be used an image scanner function are separated.
