Description

  The present invention relates to an image forming apparatus.

  For image forming devices such as copiers and multifunction devices, when specific print data designated as confidential by a user is received from a personal computer, printing is not performed immediately, and if a password is not input by an operation unit such as a touch panel, printing is performed. Some of them are equipped with a function that does not. In addition, in such an image forming apparatus, when an error that interrupts image formation such as a paper jam or out of toner occurs during printing of a confidential document, the confidential document is kept confidential. In some cases, even if the error is canceled, image formation is not resumed until a password is input. As a result, even if the user leaves the image forming apparatus during confidential printing, the content of the confidential document is prevented from leaking to others. For example, Patent Document 1 below discloses a printing apparatus in which image formation is not resumed until an input of a password or the like is performed when such an error occurs.

Next, the operation of the multifunction peripheral A according to the present embodiment configured as described above will be described in detail with reference to FIG.
First, a user who wants to print with the multifunction device A operates the client computer C to transmit a print execution request including print image data from the client computer C to the multifunction device A.

 In the MFP A, when the communication unit 6 receives the print execution request (step S1), the main control unit 7 stores the print image data received together with the print execution request in the image data storage unit 3, and responds to the print execution request. It is determined whether or not printing satisfies the confidential printing switching condition (step S2). That is, the main control unit 7 executes whether or not another user other than the user of the client computer C (the transmission source of the print execution request) is operating the operation display unit 1 and a print job of another user. And whether or not another user is logged in. If any of these conditions is met, it is determined that the classified print switching condition is met, and if none of the conditions is met, the classified print switching condition is set. Judge that it does not apply. Whether or not another user is operating the operation display unit 1 is determined by the user of the client computer C operating when the user of the client computer C logs in and operating the operation display unit 1. It is determined that the other operation display unit 1 is operated, and it is determined that another user is operating the operation display unit 1.

Returning to FIG. 2, if the main control unit 7 determines “NO” in step S <b> 2, that is, if the confidential print switching condition is not satisfied, the print image data stored in the image data storage unit 3 is converted into an image. The processing unit 4 converts the image data into print image data in an image forming format, and causes the paper transport / image forming unit 5 to perform printing based on the print image data (step S3).
If the main control unit 7 determines “YES” in step S2, that is, if the confidential print switching condition is satisfied, the main control unit 7 switches the print in response to the print execution request received from the client computer C to the confidential print, and performs the print. The paper conveyance / image forming unit 5 is put on standby (step S4).

 After step S4, the main control unit 7 determines whether or not the confidential printing execution condition is satisfied (step S5). That is, the main control unit 7 determines whether or not a print job of another user other than the user of the client computer C has been completed, and whether or not a certain time has elapsed since the other user completed the operation of the operation display unit 1. It is determined whether or not a certain time has elapsed since the other user logged out, and whether or not the user of the client computer C is in a position near the multi-function peripheral A, and the case where all the conditions are satisfied is set as the confidential print execution condition. It is determined that this is the case, and if any of the conditions is not satisfied, it is determined that the confidential printing execution condition is not satisfied.

 Specifically, as a method for determining whether or not the user of the client computer C is near the multifunction device A, for example, when the client computer C transmits the print execution request with the location information of the client computer C added, There is a method in which the main control unit 7 determines whether or not the user of the client computer C is near the multi-function device A based on the position information. At this time, the main control unit 7 performs the determination on the assumption that the user is in the ridge of the client computer C.

 In addition, when entering / exiting a room is managed by a user-owned card (for example, a non-contact IC card or a magnetic card), the main control unit 7 is located near the multi-function peripheral A based on the room entering / exiting information. When the local area network B is wireless communication, the main control unit 7 specifies the position of the client computer C based on the communication state of the wireless communication, and based on the specified result, the multifunction device A There is also a method for determining whether or not the position is near. In this case as well, the main control unit 7 performs the determination on the assumption that the user is in the client computer C.

 If it is determined as “YES” in step S5, that is, if the confidential printing execution condition is satisfied, the main control unit 7 executes printing on the paper transport / image forming unit 5 based on the print image data in step S3. Let When the main control unit 7 determines “NO” in step S5, that is, when the confidential printing execution condition is not satisfied, the main control unit 7 displays a screen prompting the user to input the password by operating the operation display unit 1. It is determined whether or not a correct password has been input (step S6).

 If the main control unit 7 determines “NO” in step S6, that is, if the correct password is not input, the main control unit 7 waits for input of the correct password in step S6, and determines “YES” in step S6. In this case, that is, when a correct password is input, in step S3, the paper conveyance / image forming unit 5 is caused to execute printing based on the print image data.

  As described above, in the MFP A according to the present embodiment, when receiving the print execution request from the client computer C (external), the main control unit 7 prints the print execution request when the confidential print switching condition is met. Switch to confidential printing. As described above, when the confidential printing switching condition is satisfied, the security printing is automatically switched to the confidential printing. Therefore, the user can execute the confidential printing without performing an extra operation.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, For example, the following modifications can be considered.
(1) In the above embodiment, the main control unit 7 determines whether or not another user other than the user of the client computer C is operating the operation display unit 1 and whether or not a print job of another user is being executed. It is determined whether or not another user is logged in, and it is determined that any of the conditions is applicable to the confidential print switching condition, but the present invention is not limited to this. For example, when the main control unit 7 receives a switching condition change instruction from the operation display unit 1 by a user operation, the main control unit 7 may change the confidential printing switching condition based on the switching condition change instruction. As for the confidential print execution condition, when the main control unit 7 receives an execution condition change instruction from the operation display unit 1 by a user operation, the main control unit 7 changes the confidential print execution condition based on the execution condition change instruction.
