Patent number: 8332933Abstract: When a user operates a processing apparatus through a touch panel, a fingerprint processing unit reads fingerprint information of the user's finger. Each time when the fingerprint processing unit reads fingerprint information, a CPU judges whether the read fingerprint information is identical to a fingerprint information of authenticated user. If being identical, the processing apparatus executes a process in accordance with an operation accepted through the touch panel. These two fingerprint information are identical each other if the operating user through the operation accepting panel is the authenticated user. It means that the processing apparatus judges whether the operating user is the authenticated user, each time when the user operates. If the user is the authenticated user, the process in accordance with the operation by this user is then executed.Type: GrantFiled: October 31, 2008Date of Patent: December 11, 2012Assignee: Sharp Kabushiki KaishaInventors: Atsushi Ogo, Yuji Okamoto, Shuhji Fujii

Patent number: 8301073Abstract: In an image forming apparatus of the present invention, when performing one-side printing during a predetermined period after two-side printing, a change in a carrying velocity of a post-process apparatus is prevented and thus recording paper having passed through a fixing section is carried and output at a velocity that is lower than a velocity for normal one-side printing and that is identical with a velocity for two-side printing. Consequently, it is possible to prevent dropping of productivity of the image forming system due to a time necessary for changing the carrying velocity of the post-process apparatus and to increase an operating ratio of the image forming system, even if the post-process apparatus is designed to completely stop the carrying roller etc. when changing the carrying velocity.Type: GrantFiled: September 16, 2008Date of Patent: October 30, 2012Assignee: Sharp Kabushiki KaishaInventors: Nobuyuki Ueda, Shuhji Fujii, Yuji Okamoto, Kenji Takahashi, Kazuhiko Ido

Patent number: 8264719Abstract: The output history of image data is made traceable when image data is processed while it is transmitted between an image processing apparatus and an external apparatus. The image processing apparatus adds specific information including information concerning the own apparatus to image data from a document. When specific information is added, either the form of writing specific information in header information of image data or the form of combining with an original image a specific image corresponding to specific information is selected. The image processing apparatus sends image data having added specific information to a management server, and the management server stores inputted image data. The management server adds information concerning the own apparatus to image data as specific information, and sends the image data to the image processing apparatus. The image processing apparatus adds information concerning the own apparatus to image data as specific information, and prints the image data.Type: GrantFiled: June 1, 2007Date of Patent: September 11, 2012Assignee: Sharp Kabushiki KaishaInventors: Yuji Okamoto, Shuhji Fujii

Patent number: 7949956Abstract: Provided are a user interfacing display apparatus having improved operability without confusing the user as to setting displayed on a pop-up screen, and an image forming apparatus. When a copy ratio key as a detail setting key is selected on an LCD as a display section provided in the user interfacing display apparatus mounted on an image forming apparatus, the pop-up screen is displayed. At the same time, a display state of an interruption key is changed, so as to be displayed to inform that the interruption key is unavailable. While the pop-up screen is being displayed, a user is not allowed to select the interruption key. Thus, for example, on contrary to a case where process is switched to an interruption mode while the pop-up screen is being displayed, there will be no confusion as to the detail setting displayed on the pop-up screen before switching to the interruption mode.Type: GrantFiled: June 24, 2003Date of Patent: May 24, 2011Assignee: Sharp Kabushiki KaishaInventors: Takashi Imai, Yuji Okamoto, Kaoru Ishikura, Shuhji Fujii, Nobuyuki Ueda, Kenji Takahashi

Patent number: 7916320Abstract: An image processing apparatus for preventing unauthorized uses of image data by allowing the addition of a specific image in a black-and-white mode even when it is set that a specific image is added in a color mode. When a document is copied, a control section determines whether the apparatus is in a color mode or a black-and-white mode. When in a black-and-white mode, an adding condition determining section reads a set security level and a differential value and determines a security level lower than the one in a color mode. Based on the security level in a black-and-white mode, an adding condition of a specific image is determined. The specific image adding section adds a specific image different from the one in a color mode based on the adding condition. A black-and-white image added with the specific image is printed.Type: GrantFiled: December 6, 2007Date of Patent: March 29, 2011Assignee: Sharp Kabushiki KaishaInventors: Yuji Okamoto, Shuhji Fujii
