BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of an image forming apparatus and a confidential document printing method of the present invention will be described in detail with reference to the accompanying drawings. 1 to 6 show an embodiment of an image forming apparatus and a confidential document printing method according to the present invention.
[0021]
FIG. 1 shows a schematic configuration of an image forming apparatus according to the present invention.
When the print key 34 on the operation unit 30 is pressed, the original bundle placed on the original table 2 in the automatic document feeder (hereinafter referred to as ADF) 1 is pressed to the lowermost position. The document is fed to a predetermined position on the contact glass 6 by the feed roller 3 and the feed belt 4.
[0022]
The fed document is read by the reading unit 50 to read the image data of the document on the contact glass 6, and the read document is discharged by the feed belt 4 and the discharge roller 5. Further, when the document set detection 7 detects that the next document is present on the document table 2, the document is fed onto the contact glass 6 in the same manner as the previous document.
[0023]
The feed roller 3, the feed belt 4, and the discharge roller 5 are driven by a transport motor 26. The transfer sheets stacked on the first tray 8, the second tray 9, and the third tray 10 are fed by the first sheet feeding device 11, the second sheet feeding device 12, and the third sheet feeding device 13, respectively, and are vertically conveyed. The sheet is transported by the unit 14 to a position where it contacts the photoconductor 15.
[0024]
The image data read by the reading unit 50 is written on the photoconductor 15 by the laser from the writing unit 57, and passes through the developing unit 27 to form a toner image. Then, the toner image on the photoconductor 15 is transferred while the transfer paper is conveyed by the conveyance belt 16 at the same speed as the rotation of the photoconductor 15. Thereafter, the image is fixed by the fixing unit 17, and the image is discharged to the finisher 100 of the post-processing device by the sheet discharging unit 18.
[0025]
The finisher 100 of the post-processing device can guide the transfer paper conveyed by the paper discharge unit 18 of the main body toward the normal discharge roller 102 and the staple processing unit. By switching the switching plate 101 upward, the sheet can be discharged to the normal sheet discharge tray 104 via the transport roller 103. Further, by switching the switching plate 101 downward, the sheet can be conveyed to the staple table 108 via the conveying rollers 105 and 107.
[0026]
The transfer paper stacked on the staple table 108 is aligned with the jogger 109 for paper alignment every time one sheet is discharged, and is stapled by the stapler 106 when a part of the copy is completed. The transfer paper group bound by the stapler 106 is stored in the stapling completion paper discharge tray 110 by its own weight.
[0027]
On the other hand, the normal paper discharge tray 104 is a paper discharge tray that can move back and forth. The paper discharge tray unit 104 that can be moved back and forth moves back and forth and sorts the discharged copy paper easily for each document or for each copy unit sorted by the image memory.
[0028]
When images are formed on both sides of the transfer sheet, the transfer sheet fed and imaged from each of the paper feed trays 8 to 10 is not guided to the discharge tray 104 side, and the branch claw 112 for path switching is set. By setting it on the upper side, it is once stocked in the duplex sheet feeding unit 111. Thereafter, the transfer paper stocked in the duplex paper supply unit 111 is re-fed from the duplex paper supply unit 111 in order to transfer the toner image formed on the photoconductor 15 again, and a branch claw 112 for switching the path. Is set on the lower side, and guided to the discharge tray 104. As described above, the double-sided paper feeding unit 111 is used when forming images on both sides of the transfer paper.
[0029]
The photoconductor 15, the transport belt 16, the fixing unit 17, the paper discharging unit 18, and the developing unit 27 are driven by a main motor 25, and the respective paper feeding devices 11 to 13 drive the main motor 25 by paper feeding clutches 22 to 24, respectively. Driven by transmission. The vertical transport unit 14 is driven to transmit the drive of the main motor 25 by the intermediate clutch 21.
[0030]

The operation unit 30 includes a liquid crystal touch panel 31, a numeric keypad 32, a clear / stop key 33, a print key 34, a list key 35, a reset key 36, an initial setting key 37, a detail confirmation key 38, and a content change key 39. The display unit 31 displays various function keys and messages indicating the status of the image forming apparatus.
[0031]
When the operator touches a key displayed on the liquid crystal touch panel 31, the key indicating the selected function is inverted to black. If the details of the function need to be specified (for example, the type of page printing), touching a key displays a setting screen for the detailed function. In the present invention, by touching the key for security management printing, user name management or number management can be selected. When the user name management is selected, a list of registered users is displayed. As described above, since the liquid crystal touch panel uses the dot display device, the optimal display at that time can be performed graphically.
[0032]
By pressing the initial setting key 37, the initial state of the machine can be arbitrarily customized. It is possible to arbitrarily set the size set when the paper size stored in the machine is set or when the reset key of the copy function is pressed. In addition, it is also possible to select an application that is preferentially selected when there is no operation for a certain period of time, to set a transition time to low power according to the ENERGY STAR plan, and to set a transition time to auto-off / sleep mode. It is possible to set.
[0033]
When the list key 35 is pressed, a list of jobs being processed by the machine is displayed on the panel. Basically, the list is arranged in the order of printing.
[0034]
When the detail confirmation key 38 is pressed, detailed information on the currently displayed job is displayed. The information is information of a single job such as “image size”, “setting mode”, “post-processing”, “density”, and “color setting”.
[0035]
When the content change key 39 is pressed, the setting content is determined once, and a screen for changing the setting content of the image print job in which the data is input is displayed. The content of the change changes depending on the setting content of the job, the configuration of the machine, the timing when the content change key is pressed, and the like.
[0036]
FIG. 3 illustrates a control device with a focus on the main controller. The main controller 20 controls the entire image forming apparatus. The main controller 20 includes an operation unit 30 for performing display to an operator, input of function setting from the operator, control of a scanner, control of writing a document image in an image memory, control of image formation from an image memory, and the like. A distributed control device such as a unit (IPU) 49 and an automatic document feeder (ADF) 1 is connected. Each decentralized control device and the main controller 20 exchange machine status and operation commands as needed. Further, a main motor 25 and various clutches 21 to 24 necessary for paper conveyance and the like are also connected.
[0037]
Returning to FIG. 1, a description will be given of a process from reading of a document by the image forming apparatus to writing of an image.
The reading unit 50 includes a contact glass 6 on which a document is placed and an optical scanning system. The optical scanning system includes an exposure lamp 51, a first mirror 52, a lens 53, a CCD image sensor 54, and the like. I have. The exposure lamp 51 and the first mirror 52 are fixed on a first carriage (not shown), and the second mirror 55 and the third mirror 56 are fixed on a second carriage (not shown). When reading a document image, the first carriage and the second carriage are mechanically operated at a relative speed of 2: 1 so that the optical path length does not change. This optical scanning system is driven by a scanner drive motor (not shown). The document image is read by the CCD image sensor 54, converted into an electric signal, and processed.
[0038]
The writing unit 57 includes a laser output unit 58, an imaging lens 59, and a mirror 60. Inside the laser output unit 58, a polygon mirror (polygon mirror) that rotates at a high speed at a constant speed by a laser diode as a laser light source and a motor. ) Is provided. The laser beam output from the writing unit 57 is applied to the photoconductor 15 of the image forming system. Although not shown, a beam sensor that generates a main scanning synchronization signal is disposed at a position near one end of the photoconductor 15 where the laser beam is irradiated.
[0039]
FIG. 4 is a block diagram of the internal configuration of the image processing unit (IPU) 49. The reflection of the light emitted from the exposure lamp 51 is photoelectrically converted by the CCD image sensor 54 and is converted into a digital signal by the A / D converter 61. The image signal converted into the digital signal is subjected to MTF correction, γ correction, and the like in the image processing unit 63 after being subjected to shading correction 62. Thereafter, the image data input via the print synthesizing unit 71 is supplied to the scaling circuit 76 or the image memory controller 65 by switching, and the image signal passed through the scaling circuit 77 is adjusted according to the scaling factor. It is scaled and sent to the writing unit 57.
[0040]
On the other hand, the image memory controller 65 and the selector 64 are configured to be able to input and output image signals in both directions. Although not specifically shown in FIG. 4, image data supplied from outside via the I / O port 67 and the telephone line communication control unit 68 in addition to the image data input from the reading unit 50 to the IPU 49, for example, It has a function of selecting input / output for a plurality of data so that data input from a data processing device such as a personal computer can be processed.
[0041]
The telephone line communication control unit 68 digitizes analog information obtained from a wireless communication network via an attached antenna (not shown), or converts data stored in an image memory 66, an HD 75, a ROM 69, a RAM 70, and an NV-RAM 74. It has the function of converting it to analog information and transmitting it to a predetermined mobile terminal via a wireless communication network. This enables data transmission and reception between a general telephone and the image forming apparatus.
[0042]
Further, a CPU 68 for setting the image memory controller 65 and the like and controlling the reading unit 50 and the writing unit 57, and a ROM 69, a RAM 70, and an NV-RAM 74 for storing programs and data thereof are provided. Further, the CPU 68 can write and read data in the image memory 66 via the memory controller 65. The original image sent to the image memory controller 65 is sent to the image memory 66 after the image data is compressed by an image compression device provided in the image memory controller. The reason for image compression here is that data of 256 gradations corresponding to the maximum image size can be written to the image memory 66 as it is, but the image memory is used very much for one document image. By performing image compression, a limited image memory can be used effectively. Also, since a large number of document image data can be stored at one time, the stored document image data can be output in page order as a sorting function.
[0043]
The image in the image memory 66 can be accessed from the CPU 68. For this reason, the contents of the image memory can be processed, and for example, image thinning processing, image clipping processing, and the like can be performed. For processing, image data processing can be performed by writing data to the register of the memory controller 65. The processed image is stored again in the image memory. The image memory 66 is configured to divide the image data into a plurality of areas according to the size of the image data to be processed and to simultaneously execute input and output of the image data. In order to enable the input and output of image data to be executed in parallel in each divided area, an interface with a memory controller is connected by two sets of address and data lines for reading and writing. As a result, an operation of outputting (reading) an image from the area 2 while inputting (writing) the image to the area 1 becomes possible. After reading all the originals (image input) of the bundle of originals, the image is being output. However, "reserved copy" for starting reading of the next original is possible.
[0044]
The image memory 66 may be provided with a separate hard disk to store a large amount of image data. By using a hard disk, there is also a feature that an external power supply is unnecessary and an image can be held permanently. In order to read and hold a plurality of fixed originals (format originals) with a scanner, the hard disk is generally used.
[0045]
The writing and reading are temporarily stored and processed in an image memory in order to absorb a difference in processing speed with respect to image formation of the main body and image writing from the scanner. When sending data from the image storage device to the writing unit 57, the data is temporarily stored in the image memory 66 and sent to the writing unit 57. The image controller 66 determines the image path of the image memory 66, the HD 75, the scanner image, and the input and output of the image to be sent to the writing unit.
[0046]
Next, a procedure for printing a confidential document in the image forming apparatus will be described by taking as an example a case where a document is copied for users A, B, C, and D participating in a conference.
FIG. 5 is a block diagram showing a simplified configuration of the image forming apparatus for simplicity of description, and FIG. 6 shows an example of a display displayed on the display unit 210. It is assumed that the confidential document to be copied has already been input to the image forming apparatus together with the administrator ID of the document. As a method for inputting the confidential document, there are various methods such as reading by a scanner, reading from a recording medium such as a floppy (R) disk, and inputting via a network.
[0047]
A confidential document administrator wants to print an important confidential document by the image forming apparatus of the present embodiment. In this case, the confidential document manager touches the confidential management print key 31 shown in FIG. 2 and inputs the manager ID and the document ID to be copied. Then, as shown in FIG. 6, a list of users registered in the image forming apparatus is displayed on the display unit 201. Since confidential documents are particularly important, users are managed by user names rather than numbers assigned to each user. Also, as shown in FIG. 6, the image forming apparatus prints a confidential document to the user, a column for identifying whether or not to print the confidential document to the user, together with the user name. And a printed confirmation column for identifying whether or not the printing has been completed.
[0048]
Since the confidential document manager has found the user A and the user B in the user name list, the confidential document administrator sets the print permission / non-permission column of the corresponding name to permission and starts printing. The names of the users A and B are printed on the entire surface of the printed confidential document. In order to change the print permission / non-permission column to printable, it is necessary to input the administrator ID of the confidential document manager and the document ID. Also, as shown in FIG. 6, the fact that the confidential document is printed for distribution to the user A and the user B is stored. In the future, when the confidential document is used for another conference in which the user A or the user B participates, if the user tries to print the confidential document for the user A or the user B, the user already has the confidential document. Printing is not accepted unless there is an appropriate permission (input of a predetermined number).
[0049]
Next, it is desired to perform printing for the users C and D, but the users C and D are not registered as users of the image forming apparatus. In this case, the confidential document manager inputs the names of the users C and D from the operation input unit 202 of the image forming apparatus. Further, when printing a confidential document, it is necessary to input a management ID and a document ID and permit printing with a corresponding name.
[0050]
Next, when a person other than the confidential document administrator attempts to print a confidential document with a user name other than the users A, B, C, and D permitted by the administrator, this person inputs the administrator ID. Therefore, printing cannot be performed with the names of users A, B, C, and D permitted by the confidential document manager. Further, since the printing has already been performed under the names of the users A, B, C, and D, the confidential document cannot be printed under the names of the users A, B, C, and D.
[0051]
If a user ID or the like is registered instead of a name when registering a user in the image forming apparatus, the same effect can be obtained by using this ID as security management print data.
[0052]
As described above, according to the present embodiment, the name of the user who distributes is printed instead of the management number in the security management printing. Therefore, it becomes clear which user the confidential document belongs to, and the responsibilities of the administrator of the document and the administrator who receives the document can be clarified, thereby preventing the leakage and duplication of the malicious confidential document.
[0053]
Further, by recording the distribution status of the confidential document, the administrator of the confidential document can be clarified, and the management of the confidential document becomes easy. Further, it is possible to reliably manage the document when collecting the printed document at a later date.
[0054]
Also, by preventing more than one copy of the same confidential document from being distributed to one user, management of the confidential document is facilitated, and leakage and duplication of the document can be prevented. As a result, flooding of confidential documents can be prevented.
[0055]
Also, by preventing printing for users who should not distribute the confidential document, leakage and duplication of the document can be prevented. As a result, flooding of confidential documents can be prevented.
[0056]
Also, by printing a character string or a number that can limit the users to which the information is distributed, the same effect as the name can be obtained. As a result, it is possible to cope with a case where it is clear to the person concerned with the confidential document to whom the confidential document has been distributed, and to want to hide the holder of the confidential document from persons having no external relations.
[0057]
In addition, it is possible to deal with a case where it becomes necessary to distribute a confidential document to a user who has not been registered.
[0058]
The above-described embodiment is a preferred embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention.
[0059]
【The invention's effect】
As is apparent from the above description, the present invention requests the input of the administrator ID and the confidential document ID of a confidential document when printing the confidential document. The name is displayed on the display means, and the confidential document is printed for the selected user. Further, the fact that printing of the confidential document has been performed with the user name is recorded, and thereafter printing of the confidential document with the same user name is not performed. Accordingly, the distribution status of the confidential document can be recorded, and more than one copy of the same confidential document can be prevented from being distributed to one user, and the administrator of the confidential document can be clearly identified. By clarifying the responsibilities of the document administrator and the administrator who receives the document, it is possible to prevent the leakage and duplication of malicious confidential documents.
[0060]
Further, the name of the user to be distributed is printed together with the confidential document data. Therefore, it becomes clear which user the confidential document belongs to, and the responsibilities of the administrator of the document and the administrator who receives the document can be clarified, thereby preventing the leakage and duplication of the malicious confidential document.
[0061]
Also, by preventing printing for users who should not distribute the confidential document, leakage and duplication of the document can be prevented. As a result, flooding of confidential documents can be prevented.
[0062]
Also, by printing a character string or a number that can limit the users to which the information is distributed, the same effect as the name can be obtained. As a result, it is possible to cope with a case where it is clear to the person concerned with the confidential document to whom the confidential document has been distributed, and to want to hide the holder of the confidential document from persons having no external relations.
[0063]
Further, when the administrator ID and the confidential document ID are input and a new user name is input, the confidential document is distributed to users who have not been registered by printing the confidential document with this user name. It is possible to deal with the case where the need arises.
