Description

  The present invention relates to an image forming system, a monitoring apparatus, an image forming apparatus, and an image forming method, and more particularly to an image forming system, a monitoring apparatus, an image forming apparatus, and an image forming method for preventing leakage of confidential information.

  There are cases where confidential information is leaked artificially and unconsciously. For example, although certain confidential information X is printed on the paper A, it may be printed again on a new paper B due to a wrong paper size. In this case, if the back side of the previously printed sheet A is a blank sheet, it can be used as a back sheet. Therefore, the document Y is printed on the blank side of the sheet A, and the sheet A on which the confidential information X is printed is distributed as the document Y. There is a fear.

As a method for preventing confidential information from being taken out of a predetermined area without permission, for example, a special tag equipped with a wireless tag such as RFID (Radio Frequency Identification) capable of writing and reading information and a magnetic wire can be used. There has also been proposed a method for restricting taking out confidential information by printing confidential information on a sheet and detecting the wireless tag or the like (see, for example, Patent Document 1).

If it is determined that they are not suitable, the print control means for controlling the print output is instructed to stop cleaning.

  In the present invention, since a predetermined sheet is used when printing or cleaning confidential information, leakage of confidential information can be prevented.

  FIG. 1 is a schematic diagram showing an example of the configuration of an image forming system according to the present invention.

  As shown in FIG. 1, the image forming system includes a print controller 10, an image forming apparatus 20, and a monitoring apparatus 30.

  The print controller 10 generates a video image of an image to be printed out by the image forming apparatus, transmits the video image to the image forming apparatus 20, and instructs printout. Further, when a jam occurs in the image forming apparatus 20 and the jammed paper is removed, a “empty” video image is transmitted to the image forming apparatus 20 to instruct cleaning.

  The image forming apparatus 20 includes a paper feed tray 21 that stores paper, an image forming unit 22 that prints an image, a transport path 23 that transports paper from the paper feed tray 21 to the image forming unit 22, and the image forming apparatus 20. And a print control unit 24 that performs processing for overall control.

  When a video image is received from the print controller 10, the print control unit 24 determines a paper feed tray to feed paper according to the video image, and the paper is conveyed to the image forming unit 22 via the conveyance path 23. Print out the image.

  Further, when a paper jam (jam) occurs, arbitrary information (jam information) related to the jam, such as a jam occurrence position and up to which video image the print output has been completed, is transmitted to the print controller 10.

  The monitoring device 30 includes an image attribute determination unit 31, a paper attribute determination unit 32, a jam information acquisition unit 33, and an attribute conformity determination unit 34.

  The image attribute determination unit 31 acquires an attribute of an image to be printed out by the image forming apparatus 20. Specifically, for example, a video image transmitted from the print controller 10 to the image forming apparatus 20 is monitored, and an identification number (see FIG. 2A) or a mark (see FIG. 2B) generated on the video image. See), and the attribute is determined and acquired based on the identification attribute such as code information such as a barcode or a two-dimensional code.

  As the attribute, for example, arbitrary information such as the type of image (information) (whether it is confidential information), the type of paper to be printed out, or the like can be used as the attribute of the image.

  The paper attribute determination unit 32 acquires the attribute of the paper on which an image is printed out. Specifically, for example, in the image forming apparatus 20, a sheet conveyed from the paper feed tray 21 to the image forming unit 22 is monitored on the conveyance path 23 and is provided on the sheet using a wireless tag reader (not shown). Information is acquired from the wireless tag, and the attribute of the paper is determined and acquired. The wireless tag reader detects whether or not the paper is equipped with a wireless tag. If the wireless tag is provided, the paper is determined to be confidential information paper. If the wireless tag is not provided, the paper is determined to be plain paper. For example, the attribute may be determined based on the presence or absence of a wireless tag. Furthermore, when an identification attribute such as an identification number, a mark, or code information is printed on the sheet, the identification attribute may be acquired by scanning the sheet, and the attribute of the sheet may be determined based on the identification attribute.

  As the attribute, for example, arbitrary information such as the type of paper (whether there is a wireless tag) and the type of printable image (attribute) can be used as the image attribute.

  The jam information acquisition unit 33 detects the occurrence of a jam in the image forming apparatus 20. Specifically, for example, a control signal transmitted from the image forming apparatus 20 to the print controller 10 is monitored, and jam information indicating a jam occurrence position or the like is acquired.

  The attribute conformity determination unit 34 determines whether or not the image attribute matches the paper attribute. If it is determined that the attribute does not match, the attribute conformity determination unit 34 instructs the print control unit 24 of the image forming apparatus 20 to stop printing. Specifically, for example, when the attribute of the image is confidential information and the attribute of the paper is a normal paper (paper without a wireless tag), it is determined that the attribute does not match. Note that the attribute conformity determination is not limited to such a condition, and can be arbitrarily set such that, for example, it is determined that the attributes do not match unless the paper is dedicated to the image attribute.

  In the image forming system according to the present invention using the above configuration, the monitoring device 30 is used to monitor the video image transmitted from the print controller 10 to the image forming device 20 and from the paper feed tray 21 in the image forming device 20. The paper conveyed to the image forming unit 22 is monitored on the conveyance path, and if the attributes of the image and the paper do not match, the monitoring apparatus 30 instructs the image forming apparatus to stop printing.

  Here, FIG. 3 is a diagram illustrating control timing in the image forming system. The timing at which the video image passes through the image attribute determination unit and the timing at which the paper passes through the paper attribute determination unit may differ depending on the position where each unit is installed. In this case, as shown in the figure, it is desirable to synchronize the corresponding video image and paper when printing out the image.

  Hereinafter, the flow of processing in the monitoring apparatus will be described in detail using an embodiment.

  In the present embodiment, an example of the flow of processing in the monitoring apparatus when an image is printed out based on a video image will be described in detail with reference to FIG.

  First, a video image transmitted from the print controller 10 to the image forming apparatus 20 is monitored by the image attribute determination unit 31 to acquire the attribute of the image (step 100), and the attribute matching determination unit 34 is notified of the image attribute. (Step 101).

  Next, when the attribute of the sheet transported through the transport path 23 is acquired by the sheet attribute determining unit 32 (step 102), the attribute of the sheet is notified to the attribute matching determining unit 34 (step 103).

  Then, the attribute match determination unit 34 determines whether the image attribute and the paper attribute match (step 104). If it is determined that the attribute matches (YES in step 104), the process ends, and the attribute match is determined. Is incompatible (NO in step 104), the print control unit 24 of the image forming apparatus 20 is instructed to stop printing (step 105).

  As described above, in this embodiment, when it is determined that the attribute of the image and the attribute of the paper do not match, the image forming apparatus is instructed to stop printing. For example, the confidential information is printed out on a normal paper having no wireless tag. For example, it is possible to prevent image formation on a sheet other than a desired sheet.

  In this embodiment, an example of the flow of processing in the monitoring device when performing cleaning will be described in detail with reference to FIG.

  First, the control information transmitted from the image forming apparatus 20 to the print controller 20 is monitored by the jam information acquisition unit 33, and when the jam information is acquired (step 200), the jam information is transmitted to the attribute matching determination unit 34 (step). 201).

  Next, a video image transmitted from the print controller 10 to the image forming apparatus 20 is monitored by the image attribute determination unit 31 to acquire the attribute of the image (step 202), and the attribute attribute determination unit 34 is notified of the image attribute. (Step 203).

  Then, when the attribute of the sheet transported through the transport path 23 is acquired by the sheet attribute determination unit 32 (step 204), the attribute of the sheet is notified to the attribute matching determination unit 34 (step 205).

  Here, the attribute match determination unit 34 determines whether the image attribute acquired by the image attribute determination unit 31 is an attribute of a cleaning image (step 206), and determines that the image is not a cleaning image. (NO in step 206), it is determined whether the attribute of the image and the attribute of the paper match (FIG. 4, step 104).

  If it is determined in step 206 that the image is a cleaning image (YES in step 206), the image forming unit of the image forming apparatus 20 is based on the history of image attributes processed by the image attribute determining unit 31 and jam information. The attribute matching determination unit 34 determines an attribute of an image (remaining image) in which toner (image) may remain in 22 (step 207).

  Then, the attribute match determination unit 34 determines whether or not the attribute of the remaining image matches the attribute of the paper (step 208). If it is determined that the attribute matches (YES in step 208), the process ends. If it is determined that the attributes do not match (NO in step 208), the print control unit 24 of the image forming apparatus 20 is instructed to stop printing (cleaning) (step 209).

The determination of whether or not the image is a cleaning image in step 206 is, for example,
It is possible to use any method such as determining whether or not the attribute of the image acquired from the “color (empty)” video image.

  As described above, in this embodiment, since cleaning can be performed using a sheet having an attribute that matches the attribute of the remaining image remaining in the image forming unit, for example, a normal sheet that does not include a wireless tag is used for cleaning. It is possible to prevent a residual image from being formed on a sheet other than a desired sheet, such as preventing the secret information from being printed out.

  By the way, in the processing at the time of cleaning described with reference to FIG. 5, it is determined whether or not the cleaning paper is suitable according to the attribute of the remaining image remaining in the image forming unit. Regardless, when cleaning is performed with a certain sheet regardless of the remaining image, such as when a sheet with a wireless tag (secret information sheet) is used as a cleaning sheet, jam information transmitted from the image forming apparatus 20 to the controller 10 It is also possible to perform processing without acquiring the above, and the flow of processing will be described in detail below with reference to FIG.

  FIG. 6 is a flowchart illustrating an example of a processing flow in the monitoring apparatus when cleaning is performed with a certain sheet (secret information sheet) regardless of the attribute of the remaining image.

  First, a video image transmitted from the print controller 10 to the image forming apparatus 20 is monitored by the image attribute determination unit 31 and the attribute of the image is acquired (step 300), and the attribute match determination unit 34 is notified of the image attribute. (Step 301).

  Next, when the attribute of the sheet conveyed through the conveyance path 23 is acquired by the sheet attribute determination unit 32 (step 302), the attribute of the sheet is notified to the attribute matching determination unit 34 (step 303).

  Here, the attribute match determination unit 34 determines whether the image attribute acquired by the image attribute determination unit 31 is the attribute of the cleaning image (step 304), and determines that the image is not a cleaning image. (NO in step 304), it is determined whether the attribute of the image and the attribute of the paper match (FIG. 4, step 104).

  On the other hand, if it is determined in step 304 that the image is for cleaning (YES in step 304), the sheet attribute acquired by the sheet attribute determination unit 32 matches the sheet attribute that is determined to be used for cleaning. If it is determined whether or not the attribute is appropriate (YES in step 305), the process is terminated, and if it is determined that the attribute is not compatible (NO in step 305), the image forming apparatus The print control unit 24 is instructed to stop printing (cleaning) (step 306).

Note that the determination of whether or not the image is a cleaning image in step 204 is, for example,
It is possible to use any method such as determining whether or not the attribute of the image acquired from the “color (empty)” video image.

  As described above, in this embodiment, since it is determined whether or not the cleaning is performed using a predetermined sheet, it is possible to select a sheet other than the desired sheet without monitoring the control information transmitted from the image forming apparatus to the print controller. It is possible to prevent a residual image from being formed.

  In each of the above embodiments, a monitoring device is provided between the image forming apparatus and the controller. However, each component forming the monitoring device may be provided in the image forming apparatus as a part of the image forming apparatus. Good.

  As described above, according to the present invention, since confidential information is not printed on paper other than designated paper (for example, paper provided with a wireless tag), confidential information leakage can be prevented.

  In addition, since the attribute of the image, which is confidential information, is generated on the video image, the system separation between the print controller and the monitoring device is improved, and the monitoring device can be attached without depending on the system composed of the print controller and the image forming device. it can.

  Furthermore, in order to determine the attribute of the paper on the transport path transported from the paper feed tray to the image forming unit, even if a paper different from a predetermined paper is mistakenly stored in the paper feed tray, It can be determined whether the paper is suitable.
