Patent number: 8077361Abstract: An optical scanning apparatus is detachably mountable in an image forming apparatus. The optical scanning apparatus includes a light source unit to simultaneously emit a plurality of light beams; an optical element unit including an optical element to focus light beams deflected by the optical element onto a surface to be scanned, and hold the light source unit in a rotatively adjustable manner; and a rotation adjustment unit to adjust a position of the light source unit relative to the optical element unit in a rotation direction when an external force acts on the rotation adjustment unit. The rotation adjustment unit is disposed at a rear end of the optical scanning apparatus in an inserting direction to the image forming apparatus or at an adjustable position when the optical scanning apparatus is installed in the image forming apparatus.Type: GrantFiled: March 7, 2008Date of Patent: December 13, 2011Assignee: Ricoh Company, Ltd.Inventor: Kazunori Watanabe

Patent number: 8027068Abstract: For an image-capturing unit having a light source and mirrors directing light reflected from a scanned document into a lens condensing the light onto a photoelectrically converting image sensor, a synthetic resin housing. The housing is composed of an open-ended upper frame having a top plate from which sidewalls extend, encompassing an internal space. A mounting surface for anchoring the light-source is formed on the upper side of the upper-frame top plate, and formed on the lower side of the upper-frame top plate is a pedestal on which the lens is supported. Mirror-support projections are formed on the lower side of the upper-frame top plate, or on the upper-frame sidewalls, to support the mirrors from below the lens. With this housing, the influence of heat from the light source on the optics is minimized, improving the mirrors' positional accuracy.Type: GrantFiled: December 21, 2007Date of Patent: September 27, 2011Assignee: Nisca CorporationInventors: Masao Shimizu, Mamoru Noda

Patent number: 7978380Abstract: An image reader has an image sensor; a carriage; a positioning portion formed at a predetermined position in a longitudinal direction of the image sensor with respect to a reference position of the image sensor; a connector portion to which an electric cable is connected and which is provided between an end of the carriage and one end in the longitudinal direction of a case of the image sensor; and an engaging portion formed in the carriage. In the image recording apparatus, since the positioning portion is engaged with the engaging portion, it is possible to use a common carriage for a plurality of types of image sensors, and an operation of connecting the electric cable becomes simple.Type: GrantFiled: June 29, 2006Date of Patent: July 12, 2011Assignee: Brother Kogyo Kabushiki KaishaInventors: Takashi Ohama, Yoshinori Osakabe, Takahiro Ikeno, Akihiro Sakakibara

Patent number: RE43087Abstract: An image scanner performing multiple scanning operations for a single scan line is disclosed. The additional scanning operations are performed between two adjacent pixels. For a double scanning mode, the CCD performs one scanning operation for a scan line at a first position. Then, the CCD is moved from the first position to a second position along the X-direction to perform the other scanning operation at the second position. The distance between the first and the second positions is a half of the distance between two adjacent pixels. The scanning data of the two scanning operations are alternatively arranged and converted into final image data. By this way, a low-pixel-density CCD can be used to obtain a high-pixel-density scanning quality.Type: GrantFiled: March 16, 2006Date of Patent: January 10, 2012Assignee: Transpacific Optics LLCInventors: Jenn-Tsair Tsai, Jone-Nun Chen, I-Chang Lu
