Patent number: 7715060Abstract: An image reading apparatus accurately determines the positions of image forming mirrors formed with an off-axis reflecting surface, while enabling any thermal expansion caused by a rise in temperature due to a rise in the surrounding temperature to be absorbed. Each image forming mirror formed with an off-axis reflecting surface comprises respective and independent units for determining the positions in the longitudinal direction, in the lateral position, and in the direction orthogonal to the reflecting surface. Holes with which the longitudinal position determining units and the lateral position determining units engage have gaps in the directions orthogonal to the position determining directions to absorb the thermal expansion caused by a rise in the temperature of the image forming mirror when the position determining units engage with the holes.Type: GrantFiled: October 1, 2003Date of Patent: May 11, 2010Assignee: Canon Kabushiki KaishaInventors: Takayuki Suga, Takeshi Aoyama, Hyoe Iwata, Yukihiro Miura, Takehiro Kishi

Patent number: 7588382Abstract: An object of this invention is to provide a sheet processing apparatus capable of cutting a sheet and recording information on the back surface of the sheet without enlarging the size of the apparatus and dropping productivity. The sheet processing apparatus which executes a predetermined processing on a sheet in which an image is recorded includes: a cutter for cutting a sheet; and a print unit for recording an information about recording to the front surface the sheet on the back surface of the sheet, wherein an action of cutting the sheet with the cutter and an action of recording on the back surface of the sheet with the print unit are executed in parallel.Type: GrantFiled: August 7, 2006Date of Patent: September 15, 2009Assignee: Canon Kabushiki KaishaInventors: Akihiro Sato, Hyoe Iwata

Patent number: 7379700Abstract: A document reading apparatus includes a feeding roller for feeding a document, a reading unit for reading images of the document fed by the feeding roller and a substantially U-shaped document transfer path for guiding the document fed the feeding roller. The substantially U-shaped document transfer path is constituted by an internal guide and an external guide. The external guide is separated from the internal guide by rotating the external guide. The internal guide is rotatably disposed and supports the reading means. A reading transfer path in which the reading unit is arranged is opened by rotating the internal guide.Type: GrantFiled: April 29, 2004Date of Patent: May 27, 2008Assignee: Canon Kabushiki KaishaInventor: Hyoe Iwata

Patent number: 7021543Abstract: An image reader adopting an off-axial optical system, an adjustable imaging mirror and a CCD fixed to a highly rigid structure. Since the relative position between reflecting and imaging mirrors can be set highly accurately, adjusting only the CCD-mounting position allows a required specification of the read image to be met. The imaging mirror can easily be adjusted without distorting the reflecting surface. The reflecting and imaging mirrors, and the CCD-mounting-position adjuster are positioned directly to reflecting-mirror supporting sections, imaging-mirror supporting sections, and CCD supporting sections, which are integrated with a carriage casing, and fixed to them. The CCD is fixed to the carriage casing with the CCD-mounting-position adjuster. An imaging mirror close to a diaphragm and adjacent to the image is supported by a mirror adjusting plate, which can be displaced to adjust the position of the imaging mirror.Type: GrantFiled: April 29, 2004Date of Patent: April 4, 2006Assignee: Canon Kabushiki KaishaInventors: Takeshi Aoyama, Hyoe Iwata, Yukihiro Miura, Takehiro Kishi, Takayuki Suga

Publication number: 20050232667Abstract: The image forming apparatus includes an image bearing member rotated in a predetermined direction and serving to bear an image; and toner removal means including a first touchable/detachable member touchable on or detachable from the image bearing member and detached from the image bearing member in an area there not bearing the toner image, and second touchable/detachable member touchable on or detachable from the image bearing member, and positioned in a downstream side of the first touchable/detachable member in the predetermined rotating direction of the image bearing member, thereby eliminating a toner on the image bearing member; wherein the first touchable/detachable member and the second touchable/detachable member are detached from the image bearing member at approximately same positions. Thus a distance of toner images formed on the image bearing member can be reduced, thereby reducing a time required for image formation.Type: ApplicationFiled: April 13, 2005Publication date: October 20, 2005Applicant: Canon Kabushiki KaishaInventor: Hyoe Iwata
