Abstract: An image forming apparatus includes a controller that executes virus quarantine using a pattern file, and a storage that stores the pattern file. The controller, when being connected to a network, determines whether the pattern file stored in the storage is updatable, and when it determined that the pattern file is updatable, the controller updates the pattern file, and executes virus quarantine by using the updated pattern file.

Abstract: An eccentric butterfly valve that maintains high sealability when closed even when a high-pressure fluid is oriented in either direction of a forward flow or backflow. The valve includes a disk (23) axially supported at an eccentric position via a stem (22) inside a body (21). The disk is provided to a seat ring (24) fixed with a seat retainer (25) so as to be hermetically sealable. A flexible part is formed on an inner diameter side of the seat ring, and a spring member is mounted between the flexible part and the seat retainer. In the spring member, a load increases substantially in proportion to the magnitude of tilt of the flexible part when the disk is displaced to a seat retainer side. When the flexible part is elastically deformed, the spring member is elastically deformed in a state where contact with the seat retainer is avoided.

Abstract: A user authentication device includes a user authentication setter that enables or disables a predetermined plurality of authentication methods, and a user authenticator that accepts user authentication by the authentication method that the user authentication setter enables, and a controller that controls the user authentication setter and the user authenticator. When the user authentication setter accepts a setting that enables a single authentication method among the plurality of authentication methods, the controller controls the user authentication setter to disable all authentication methods other than the single authentication method, and the user authenticator accepts only user authentication by the single authentication method.

Abstract: A display processor of a controller extracts data such as images and characters from display data stored in a storage based on setting information stored in the storage, and displays a document orientation instructing pane and a 90-degree rotation operation icon in a document image operating pane on a display device. The display processor also displays a print preview image based on the document image data. When a rotation operation is performed through the 90-degree rotation operation icon, the document image data is also subjected to the same rotation process.

Abstract: An image forming apparatus includes: an image former; a display showing an image formation setting screen; an operator accepting a user command; a storage; and a controller. If the operator accepts a setting registration command when the display shows the setting screen, the controller stores setting contents of the setting screen along with an image of the setting screen in the storage. If the operator accepts a setting call command, the controller makes the display show a list of images of setting screens related to the setting contents stored in the storage. If the operator accepts a command to select an image from the list of images of setting screens, the controller makes the display show a setting screen, to which setting contents related to a selected image are reflected.

Abstract: When displaying a N-up image view in which a plurality of thumbnail images displayed in given windows are grouped and displayed in a single window by using a detecting section for detecting a contact position on a display screen of a display section, position specifications for the N-up image view of thumbnail images in the windows are received based on a contact position in the window in selecting thumbnail images to be displayed in the N-up image view by making contact with the thumbnail images, and the thumbnails images are displayed in the N-up image view based on the received position specifications.

Abstract: An image forming apparatus includes an operating section, a control section and an image display unit. The operating section accepts inputting operations for settings on information on an image forming size of an original image and a setting on a paper sheet size. The control section compares the image forming size with the paper sheet size, and outputs, if the image forming size exceeds the paper sheet size at least in either of a lengthwise direction and a lateral direction, a notice signal to cause a notice to that effect. The image display unit displays a preview image based on the notice signal.

Abstract: An image processing apparatus that is capable of determining a document size with high accuracy, even when a device for detecting the document size is not placed therein and an input operation of the document size by a user is eliminated is provided. A page background determining section extracts candidates for page backgrounds from input document image data and determines the number of page background types. A white pixel counting section counts the number of white pixels from input document image data. A document size determining section determines the document size of the input document image data, based on the number of page background types determined by the page background determining section, a page background density value which is the lowest density value in one or a plurality of page background areas determined to be page backgrounds, and the number of white pixels extracted by the white pixel counting section.

Abstract: Based on average values for respective color components calculated by an average value calculating section, a histogram generating section obtains, for respective pixels of interest, a maximum value of the average values among the color components and a maximum difference in the average values among the color components, and generates histograms respectively for the maximum value and the maximum difference in which histograms a number of pixels for a density bin is considered as a frequency-of-occurrence value. A determination section obtains a number of density bin having a predetermined frequency-of-occurrence value or more for each of the histograms for the maximum value and the maximum difference, and determines that the data of image is of a blank page image when both of the numbers of density bins are not greater than a bin threshold value which is set according to scanning modes or printing modes.

Abstract: An average value calculating section calculates, for respective color components, an average value of pixel values within a pixel block, to define the calculated average values as a pixel value of a pixel of interest. A histogram generating section obtains, for respective pixels of interest, a maximum value of the average values among the color components and a maximum difference in the average values among the color components, and generates histograms respectively for the maximum value and the maximum difference in which histograms a number of pixels for a density bin is considered as a frequency-of-occurrence value. A determination section obtains numbers of density bins that correspond to a frequency-of-occurrence value greater than or equal to a predetermined frequency-of-occurrence value in the histograms, and determines that data of image is of a blank page image when both of the numbers of density bins are a bin threshold or less.
