Description

  The present invention relates to an image forming apparatus that forms an image on an image forming medium such as paper.

  Some image forming apparatuses such as multifunction peripherals can perform private printing when printing highly confidential documents. Private printing is executed, for example, according to the following flow. First, a user creates a document using a personal computer or the like, and transmits information (image information) corresponding to the document (image) from the personal computer to the multifunction peripheral. Here, identification information used when an image is formed on a sheet is added to the image information transmitted to the multifunction peripheral. When the multifunction device receives image information from the personal computer, the multifunction device stores the image information in the storage unit. The user moves to the multifunction device and inputs identification information to the multifunction device in order to form an image based on the image information stored in the storage unit on the sheet. Then, the multifunction device compares the identification information input by the user with the identification information added to the image information stored in the storage unit. If the identification information matches, the multifunction device displays an image based on the image information. Form on paper.

  In a multifunction machine capable of performing such private printing, a period during which image information can be stored in the storage unit is set in order to secure a capacity of the storage unit for storing image information. In some cases, the image information is automatically deleted from the storage unit when the number is exceeded (see Patent Document 1).

In other words, the login / logout processing unit 91 logs into the multifunction device 1 when the identification information input to the multifunction device 1 based on the user's operation matches the identification information stored in advance in the storage unit 80. Process. The login / logout processing unit 91 executes logout processing from the multifunction device 1 based on user operations. The identification information input to the multifunction device 1 is input, for example, by reading the identification information stored in the IC card by an IC (Integrated Circuit) card reader.

  The determination unit 92 determines whether or not the identification information included in the image information stored in the storage unit 80 matches the identification information authenticated when the login / logout processing unit 91 performs the login process. To do. If the determination unit 92 determines that the identification information included in the image information matches the identification information authenticated by the login / logout processing unit 91, the engine unit 3 determines that they match. An image can be formed on the paper T based on image information including the same identification information as the identification information. That is, the engine unit 3 can perform private printing. On the other hand, when the determination unit 92 determines that the identification information included in the image information and the identification information authenticated by the login / logout processing unit 91 do not match, the engine unit 3 performs private printing. I can't.

  The warning control unit 93 causes the touch panel 71 to output a warning when the determination unit 92 determines that the pieces of identification information match and the time measured by the time measuring unit 110 reaches a predetermined time. Control. That is, the warning control unit 93 is in a state where private printing can be performed by the engine unit 3, and when the time counted by the timing unit 110 reaches a predetermined time, the private printing is not performed. The touch panel 71 is controlled to display a warning indicating the above. Here, the predetermined time is a time for deleting the image information stored in the storage unit 80 (image information retention time limit). The predetermined time is appropriately set by the user.

  When the determination unit 92 determines that the pieces of identification information match and the engine unit 3 forms an image based on the image information on the paper T, the storage unit control unit 94 stores the image information. Delete from 80. That is, the storage unit control unit 94 displays the warning on the touch panel 71 based on the control of the warning control unit 93, and then, when the private print is performed, the storage unit 80 stores the image information on which the private print has been performed. Delete from. Therefore, even when the time counted by the time measuring unit 110 reaches a predetermined time, the storage unit control unit 94 determines that the time counting by the time measuring unit 110 is predetermined if the login / logout processing unit 91 performs the login process. The image information that has reached the time is not deleted from the storage unit 80. In addition, when the private print is performed before the warning is displayed on the touch panel 71 based on the control of the warning control unit 93, the storage unit control unit 94 stores the image information on which the private print has been performed in the storage unit 80. Delete from.

  Further, the storage control unit 94 controls the touch panel 71 so that the warning control unit 93 outputs a warning, and the engine unit 3 does not form an image based on the image information on the paper T, and the login / logout processing unit. When the logout process is performed in accordance with 91, the image information is deleted from the storage unit 80. In other words, when the warning is displayed on the touch panel 71 and the logout process is performed without performing the private print, the storage unit control unit 94 stores the image information that is the target of the warning. Delete from 80.

  The storage unit control unit 94 also stores the image stored in the storage unit 80 when the login / logout processing unit 91 does not perform the login process and the time counted by the timing unit 110 reaches a predetermined time. Delete information. That is, the storage unit control unit 94 sets the time counted by the time measuring unit 110 to a predetermined time without performing the login process even though the storage unit 80 stores image information to be privately printed. If it has arrived, the image information that is to be timed by the time measuring unit 110 is deleted from the storage unit 80.
