  • Publication number: 20130021424
    Abstract: An optical writing apparatus includes a light source device that includes a VCSEL having an alignment of at least two channels in a sub scanning direction configured to emit plural light beams in a block. A deflector deflects the plural light beams toward an image bearer that forms an image by changing a line speed of image formation. A control device decreases a number of light beams by turning off a prescribed same number of the channels symmetrically from the both ends of the alignment in accordance with the line speed.

  • Publication number: 20120182579
    Abstract: According to this invention, the date range can be intuitively designated by designating up, down, left, and right directions, and images stored in a storage medium can be easily restricted to images which may be subjected to printing. In order to restrict images stored in a memory card on the basis of the date, a region for inputting the start date of the date range is displayed at the upper portion of a display window on a display device, and a region for inputting the end date is displayed at the lower portion. One of the regions is designated and selected with up and down direction keys. A date in the selected region is changed with left and right direction keys. Images having storage dates between the start date and the end date are decided as printing target candidates.

  • Publication number: 20120133674
    Abstract: A preferred embodiment of the present invention provides an electronic device in which a status, in which an image in a boundary region between image displaying parts is not or hardly seen, is solved in an electronic device in which a large screen is constructed by a plurality of image displaying parts. The electronic device has a display function that displays image data of a region whose width is defined by the predetermined number of pixels in one of displaying parts with respect to the image data on a boundary region where the image cannot be displayed when first and second displaying parts are used as one displaying part.

  • Patent number: 8022347
    Abstract: A surface-emitting laser array includes a plurality of surface-emitting laser devices arranged in an array. An optical system includes a plurality of optical devices to guide a light beam composed of lights emitted from the surface-emitting laser array to a target surface to be scanned. A light-intensity-control-device switching unit places one of light-intensity control devices having different light transmittances at a predetermined position in an optical path of the light beam.

  • Publication number: 20090265626
    Abstract: A print preview image of structured document data including link information is generated and displayed in a display unit, and location information indicating a position of a linked area in the print preview image is generated. The linked area corresponds to the link information included in the structured document data. If it is determined that a user specifies a linked area in the print preview image, linked data indicated by the link information corresponding to the linked area is acquired and the acquired linked data is displayed. This allows the user to refer to information about the linked data without clearing a print preview mode to switch the display mode to a browsing mode.

  • Publication number: 20090161134
    Abstract: In an apparatus connected to a plurality of input devices, in the case of a browsing mode of images stored in a device from which images are input, a user is allowed to select, in parallel, from the images stored in the input device and images showing interfaces capable of connecting to the other devices. Further, if an image indicating an interface is selected, the interface changes to an input mode of image data. Thus, the user is allowed to input image data from the other input devices without returning to the setting screen of an input device in such a mode.

  • Patent number: 7515322
    Abstract: A beam scanning device includes a light source to emit a light beam, an optical deflector to deflect the light beam, and an optical system including a f? lens to guide the defected light beam to a scan surface to form an image thereon. The beam scanning device also includes a synchronization detecting sensor to detect the deflected light beam outside an area of the image, a light blocking member configured to block the deflected light beam on an exit side of the f? lens outside an effective scan area that includes the area of the image and also includes an optical path extending to the synchronization detecting sensor. The beam scanning device further includes a metal housing accommodating the light source, the optical deflector, the optical system, the light blocking member, and the synchronization detecting sensor.

  • Patent number: 7400842
    Abstract: Heat exhaust holes are provided in a unit frame at positions just above respective imaging units. An exhaust fan causes air heated at developing elements to be exhausted outside an apparatus via heat exhaust ducts and a common duct. The heat exhaust holes are formed in different sizes depending on a position of the imaging unit. The closer the position of the imaging unit is, the larger the heat exhaust hole provided above the imaging unit is.
