An image forming apparatus has an optical device for image magnification change. The apparatus is provided with a fixed platen on which a document is placed, four reflecting mirrors and an exposure lamp by which the document is exposed and scanned, and a lens unit including a fixed-focus lens by which an image of the document is formed on an image carrier. An imagewise light emitted from a document is reflected by the first, second and third reflecting mirrors and is transmitted through the fixed-focus lens. The reflected light is projected into the image carrier by way of the fourth reflecting mirror at which the light transmitted by the fixed-focus lens is reflected. The lens unit accommodates the fixed-focus lens and is movable in the same moving direction as the first, second and third reflecting mirrors at the time of an image magnification change operation. A lens cam member is mounted on the lens unit. The lens cam member has a first cam surface for enlargement and a second cam surface for reduction on at least one side thereof. An operation member has a first operation member which carries the cam surface for enlargement operations, and a second operation member which carries the cam surface for reduction operations. An interlock member interlocks with the fourth reflecting mirror so that a moving amount of the first operation member when engaged with the first and second cam surfaces, causes a movement of the fourth reflecting mirror based on the movement amount of said operation member.

An inkjet recording apparatus, including: a conveyance device including an endless belt which conveys a recording medium placed on an exterior surface of the endless belt; a recording device which jets ink onto the recording medium conveyed by the conveyance device; and a cleaning device to clean the surface, including, a flexible sheet member mounted more downstream in a conveyance direction of the belt than a position where the recording device is mounted, and a top of the flexible sheet member comes into slidably contact with the surface, and an elastic supporting member mounted at a side of the flexible sheet member; wherein when the flexible sheet member bends due to running of the belt, the elastic supporting member comes into contact with the flexible sheet member, and the elastic supporting member pushes the flexible sheet member so that the flexible sheet member presses against the surface of the belt.
摘要:
A contents transfer system which includes a transmitter for transmitting a compressed contents via a network, and a terminal for inputting the contents transmitted from the transmitter via the network and outputting the input contents to a recording/reproducing media according to user's specification. A user can acquire the contents within the recording/reproducing media.
摘要:
A position adjusting structure for adjusting a position of a recording head with respect to a recording head mounting portion of a printer main body, the position adjusting structure including: a head mounting plane arranged on the recording head mounting portion; an adjusting member, which is transferable along a direction substantially perpendicular to the head mounting plane; and an inclined flat plane, which is arranged on either one of the recording head mounting portion or the adjusting member and is inclined against the head mounting plane; wherein, the adjusting member transfers the position of the recording head with respect to the recording head mounting portion according with transfer of the adjusting member.
摘要:
An image forming apparatus, having a sheet ejection section, provided in an upper portion of the image forming apparatus, for ejecting a recording sheet onto an upper surface portion of the image forming apparatus; a sheet post-processing apparatus for receiving the recording sheet, ejected from the sheet ejection section, so as to perform a post-processing operation upon the recording sheet; and a coupler for coupling the sheet post-processing apparatus with the image forming apparatus so that at least a part of the post-processing apparatus is located on the upper surface portion of the image forming apparatus.
摘要:
A fixing apparatus for use in an electrophotographic copying machine for fixing a toner image on the surface of a recording paper. The fixing apparatus is provided with a fixing means to fix the toner image on a recording paper, ejecting means to eject the recording paper after the fixation of the toner image and a correcting roller located along the ejecting path of the recording paper to correct a curl of the recording paper induced during the fixing process by bending the recording paper in an opposite curvature of the curl.
摘要:
A belt conveying device includes: at least three rollers, about which an endless belt to convey an object, is entrained, including an oscillation roller having a rotation shaft, whose one end is fixed and another end is oscillatably supported; a belt detection sensor provided adjacent to a side edge of the belt, which detects presence of the belt; and a belt skew controller which controls the oscillator to oscillate the oscillation roller according to a preset control value in a predetermined range to correct skew. The oscillator moves a rotation center of a movable edge of the oscillation roller along a tangential line of an ellipse having elliptical focuses corresponding to rotation centers of rotation shafts of the two rollers, other than the oscillation roller, positioned respectively in upstream and downstream of and adjacent to the oscillation roller in a belt conveyance direction.
